The reason for the increase in fuel consumption of Diesel Generator Set In the statistics of the cost of diesel generator set use, when there is a large amount of fuel consumption at a certain stage, it is necessary to consider whether the fuel supply of the injection pump is too high. The common reasons for the fuel supply of the diesel generator set are the following three reasons: 1.The fuel supply of the fuel injection pump is too large 2. The adjustment screw that restricts a large number of racks in the speed adjuster has been adjusted too large, or the throttle handle restriction screw has been adjusted 3. Excessive oil in the governor will increase the supply of oil and cause "tag cars". When the fuel supply is too large, the fuel consumption increases and the fuel is not completely burned. The diesel generator exhaust is black smoke, which accelerates the serious carbon deposits in the combustion chamber, accelerates the wear of the cylinders, pistons and piston rings, and even the diesel generator set Overheating and bumping.

Noise reduction tips for Diesel Generators How to reduce the noise of diesel generators as much as possible during the use of generators? Reducing noise from diesel generators is a trick. First, the production of fireproof and soundproof doors The thickness of the metal frame made of steel plate is about 100mm. The size is determined by the size of the engine room and the size of the diesel generator. The interior is equipped with sound insulation materials, and the outside is a metal iron plate. Second, the design of the machine room air intake silencer It is made of steel plate with built-in sound-absorbing material, which has the characteristics of light structure and elegant appearance. The air enters the machine room through the air-supply silencing air groove. Third, the design of the machine room exhaust air silencer The diesel generator set fan forcibly cools the water tank, the hot air is discharged from the engine room through the exhaust air silencing tank, and the noise is also emitted from the silencing air duct. The silencing air duct can effectively reduce the intensity of the noise. Silence groove is made of steel plate and sound-absorbing material. Fourth, the sound insulation of the diesel generator room According to the specific conditions of the computer room, there are two structures for the muffler system. One is the design of the muffler wall in the machine room, and the other is a perforated plate on the surface of the inner wall of the machine room as the mute wall. Fifth, silencer production of the unit exhaust system In order to prevent the exhaust pipe and the indoor muffler from releasing heat in the machine room, the smoke exhaust pipe and the indoor muffler are wrapped with fireproof materials to reduce the unit's heat emission to the machine room. In order to improve the noise reduction effect of the exhaust gas, secondary mute must be adopted. In general, the first-stage silent diesel generator set has been installed, and the second-stage silent device adopts anti-silence device, which makes the sound insulation effect more obvious.

Preparation before starting the Diesel Generator Set 1. Check the oil level of the lubricating oil, the liquid level of the coolant, and the amount of fuel; 2. Check the oil supply, lubrication, cooling and other systems of the diesel engine for leaks and leaks in the pipelines and joints; 3. Check the electrical circuit for potential leakage of electricity such as broken skin, whether the grounding line electrical circuit is loose, and whether the connection between the unit and the foundation is firm; 4. If the ambient temperature is below zero, a certain proportion of antifreeze must be added to the radiator; 5. The diesel generator set starts up again after the first start or stop. It should first press the pump to drain the air in the fuel system. Start Up: 1. After closing the insurance in the control box, press the start button and press the button for 3~5s. If the startup is unsuccessful, wait for about 20s to start again. If the startup is unsuccessful, the startup operation should be stopped, and the fault factor such as the battery voltage or the oil circuit should be eliminated, and then restarted; 2. Several oil pressures should be observed during start-up. If the oil pressure is not displayed or is low, stop it immediately. Run: 1. After the unit is started, check the parameters of the control box module; oil pressure, water temperature, voltage, frequency, etc.; 2. Under normal circumstances, the speed of the unit directly reaches the rated speed after starting the unit; for units with idle speed requirements, the idle time is generally 3~5min, and the idle time is not too long, otherwise the generator related components may be burnt out; 3. Check the leakage of the oil circuit, waterway and electrical appliances of the unit; 4. Check the fastening of each joint of the unit to see if there is looseness or severe vibration; 5. Observe whether the various protection and monitoring devices of the unit are normal; 6. When the speed reaches the rated speed, after the parameters of the no-load operation are stabilized, the power is turned on; 7. Check whether the parameters of the control panel are within the allowable range, check the vibration of the unit again, and whether there are three leaks and other faults; 8. It is strictly forbidden to overload when the unit is running. Normal shutdown: It must be opened before stopping, and it should be stopped after 3~5min after general unloading. Emergency stop: 1. When an abnormal situation occurs in the operation of the generator set, it must be stopped immediately; 2. During an emergency stop, press the emergency stop button or quickly push the fuel pump stop control handle to the parking position. Maintenance matters: 1. Diesel filter replacement time is 300H; air filter replacement time is every 400H; oil filter first replacement time is 50H, and later is 250H. 2. The first replacement time of the oil is 50H, and the normal replacement time of the oil is 250H every time. Operating procedure 1. Before starting, check whether the fuel tank is full or not, and there is no oil leakage at each oil pipe and joint; whether the cooling system water is sufficient, clean, no leakage, and whether the fan belt is tight. Check that the internal combustion engine and the generator transmission part should be connected reliably, the wire of the output line is well insulated, and the instruments are complete and effective. 2. After starting, run at low speed for 3 to 5 minutes, and wait until the temperature and oil pressure roller are normal before starting work. The generator should have no abnormal sound during the speed increase, and the brush on the slip ring and the commutator should have good contact, no jumping and sparking. After the operation is stable, the frequency and voltage reach the rated value before the power can be supplied. 3. When abnormal noise, odor, sharp rise in water temperature, and sharp drop in oil pressure occur during operation, stop the machine immediately and check for trouble. 4. The generator power factor must not exceed the late phase (hysteresis) of 0.95. The frequency value must not vary by more than 0.5HZ. 5. Before stopping, first cut off the main switch of each power supply branch, gradually reduce the load, then cut off the generator main switch, return the field varistor to the maximum value of the resistor, reduce the voltage to the lowest value, and then cut off the excitation switch and The grounding switch is used to stop the internal combustion engine.

As an indispensable part of the data center computer room, the generator set is particularly important for its normal operation. In order to ensure the normal operation of the generator and play its due role, the following aspects should be paid attention to when installing the generator: 1. The installation location of the diesel generator set should be well ventilated, the generator end should have sufficient air inlet, and the diesel end should have a good air outlet. The area of the air outlet should be more than 1.5 times the area of the water tank. 2. The surrounding area of the diesel generator installation should be kept clean to avoid placing nearby items that can produce corrosive gases and vapors such as acid and alkali. Conditional fire extinguishing devices should be provided. 3. For indoor use, the exhaust pipe must be led outside, the diameter of the pipe must be ≥ the diameter of the pipe of the muffler, and the elbow of the pipe to be connected should not exceed 3 to ensure the smooth discharge of smoke, and the pipe should be Tilt down 5-10 degrees to avoid rainwater injection; if the exhaust pipe is installed vertically upwards, a rain cover must be installed. 4. When the foundation is made of concrete, the level should be measured with a level gauge during installation to fix the unit on a level basis. There should be a special shock pad or foot bolt between the unit and the foundation. 5. The unit casing must have reliable protection grounding. For generators that need to be grounded directly at the neutral point, neutral grounding must be carried out by professional personnel, and lightning protection devices should be equipped. It is strictly forbidden to use the grounding device of the mains to carry out the neutral point. Directly grounded. 6. The bidirectional switch between the generator and the mains must be very reliable to prevent reverse power transmission. The wiring reliability of the bidirectional switch must be verified by the local power supply department.

Start operation instructions of Diesel Generator Set 1. Add antifreeze to the good diesel generator set. The proportion of antifreeze is detailed in the engine manual. 2. Add oil to the unit. The engine type is generally APICF-4, W15/40CF grade oil. The oil should be added to the engine's oil level gauge and the scale is full. The oil is too much and too little for the engine. unfavorable. 3. Turn on the fuel line and drain the air in the oil pipe to easily start the diesel generator set. The fuel is made of domestic No. 0 or No.-10 light diesel oil. 4. According to the power of the generator set, select the wire suitable for the current carrying capacity, and connect it to the output end of the main circuit output circuit breaker. Pay attention to the phase line and the neutral line when wiring. Do not connect the wrong one. According to the circuit diagram, check whether the wiring of the controller and the peripheral are correct, and avoid the wrong line; mainly check the communication line between the controller to the speed control board, the AVR board and the unit (using the shielded wire), and ensure that the shielded wire is completely grounded. 5. Connect the battery cable. Do not connect the positive and negative poles when wiring. Connect the positive battery cable first and then the negative battery cable. Also check if the battery is fully charged to ensure that the "starter motor" is started and start the engine. 6. Check the bolts of the main connecting part of the unit, check the fixing bolts of the instrument and components in the control panel, and the bolts of the wire terminal should be tightened. 7. The main circuit breaker should be in the off position before starting the machine. Check the wiring of the electric switch and observe if the electric switch is working properly. 8. Check if the grounding of the controller is good (connected to the engine casing), and the unit and the ground, the cabinet (low noise), and the control cabinet should be grounded reliably with the earth. 9. Start the engine manually, adjust the speed and voltage after the engine is running normally. 10. Confirm that the controller can normally adjust the speed and voltage by adjusting the software. 11. Confirm that the controller can normally control the opening and closing by manual closing or opening. 12. Before paralleling, ensure that the single machine is running normally and adjust the gain and stability of the engine. 13. After manual loading, check if the engine is running normally. 14. After the manual parallel debugging is normal, you can consider automatic paralleling. 15. The above checks are correct, and the test run is started. Before the load is put into operation, check the phase sequence, whether it is in phase with the mains, confirm the correctness, and then put it into the load.

Influence of climatic environment on power of Diesel Generator Set Generator power and operating conditions are affected by the environment, especially the ambient temperature, as well as the altitude at which the generator set is located. In general, the following common conditions can adversely affect diesel generator sets: 1. Rainwater; 2, dust or sand; 3. If the diesel generator set is operated by the sea, the environment such as salt water or fog can easily oxidize the surface layer of the diesel generator set; 4, the air contains other gases as chemical corrosion gases, such as sulfur dioxide, carbon dioxide, etc.; Therefore, in order to ensure the normal operation of the generator, we must fully consider the impact of various complex climates on the operation of diesel generator sets. For general diesel generator sets, different measures should be taken in different environments to adapt to different climates. Environmental factors such as humidity, altitude and temperature will have an impact on the operation of diesel generator sets. Other factors will also affect the normal operation of diesel generator sets, which will be more complicated in practical applications. First, the power calibrated by the diesel engine is for a specific environmental condition. Environmental conditions refer to the ambient atmospheric pressure, temperature and relative humidity of the diesel engine operating location, which have a great impact on the performance and efficiency of the diesel engine. When the ambient atmospheric pressure decreases, the temperature rises and the relative humidity increases, the dry air drawn into the cylinder of the diesel engine will decrease, and the power of the diesel engine will decrease. On the contrary, the power of the diesel engine will increase.

Five Ways to Diagnose The Problem of Diesel Generator Sets 1. Listening method: Listen to the sound of each cylinder explosion with a stethoscope or a metal stick near the injector body. The normal sound is similar to the sound of a metal tapping "Dangdang". If there is only a "squeaky" sound that is not crisp, the tank will supply too little oil or will not catch fire in time. If the tap is large, the cylinder is too large or the injection time is too early. 2. Color observation method: The diesel engine works normally, and the color of the discharged exhaust gas is slightly lighter and lighter. If black gas is discharged, it means that the combustible gas is not completely burned. Blue smoke indicates that the lubricating oil is burning into the cylinder. When the white smoke is discharged, it means that there is water in the diesel fuel and the white smoke is not burned. The exhaust pipe continuously discharges the abnormal smoke color, indicating that the respective cylinders are not working properly. 3, temperature sensing method: the most out of the diesel engine after the start of the stage (after a period of work, the temperature of the tube is very high, the hand will be burned) by hand to touch the temperature of each cylinder exhaust pipe manifold, can identify the work of each cylinder Happening. If the temperature of a cylinder exhaust manifold is higher than other cylinders, it indicates that the cylinder oil supply is high; if the temperature is low, the cylinder oil supply is small, or it does not burn completely after fuel injection or fuel injection, or does not burn. 4. Pulsation method: The pinching of the high-pressure fuel pipe by hand feels the pulsation of the fuel injection pump. Small pulsation: the oil supply with weak sound and low temperature is less; the abnormal sound of the explosion and the high temperature are the fuel injection pressure drop of the injector, the injection atomization is bad, or it can not be fired and completely burned in time. Large pulsation: the cylinder with strong sound and high temperature is too large for oil supply; the sound is weak and the temperature is low and the injector is stuck or the needle is stuck. 5. Oil cut method: In order to accurately determine which cylinder is faulty, the high pressure manifold can be cut off from the cylinder to the injector oil line to stop working to observe the change of diesel engine working condition. When the cylinder oil circuit is cut off, if the diesel engine speed and sound do not change or change little, the cylinder is working normally. Such as intermittent knocking, black smoke. When the oil circuit of a certain cylinder is cut off, the fault phenomenon disappears, indicating that the fault is in the cylinder.

How to improve the starting performance of Diesel Generator Set When the diesel generator set is cold-started, the failure to reach the compression-ignition temperature of the diesel fuel is an important reason that affects the starting performance. In this regard, hot water can be added to the engine cooling system for preheating, which is an effective way to improve startup performance. The specific approach as below: Continuously heat the water (let the water flow out of the cylinder) and gradually increase the water temperature into the small diesel generator set for preheating. When the temperature of the flowing water is high, the water discharge switch is closed. In addition, the oil pan can be heated by an open flame such as a blowtorch to improve the flow performance of the oil to reduce the movement resistance of the machine, and also to ensure sufficient capacity and good battery. The performance, which also helps improve the starting performance of the diesel engine. Improve the sealing performance of the cylinder: One of the differences between a diesel engine and a gasoline engine is the compression ignition type, so the cylinder is required to have a high sealing performance. When the engine is cold-started in winter, there is little oil on the piston ring and the cylinder wall, and the sealing effect is not good, and there is a phenomenon that it is repeatedly started and cannot be ignited. Sometimes due to the heavy cylinder wear, the sealing performance of the cylinder is seriously affected, making starting more difficult. In this regard, the injector can be removed, and 30-40 ml of oil is added to each cylinder to enhance the sealing performance of the cylinder and increase the pressure during compression. Eliminate air in the oil circuit: Loosen the bleed screw on the high pressure oil pump and pump the oil by hand to drain the air in the low pressure oil circuit; then, drain the air in the high pressure oil circuit. The specific method is: loosen the oil pipe joints on the fuel injectors, so that the throttle valve is at the maximum oil supply position, and rotate the crankshaft until the oil injectors of the fuel injectors of each cylinder are in a short supply.

How to extend the using time of Diesel Generator Set First of all, it is clear that the consumable parts of the generator set include three filters, an air filter, an oil filter and a diesel filter, to extend the service life of the diesel generator set. It is necessary to strengthen the maintenance of the three filters of the air filter, the oil filter and the diesel filter to fully exert their functions. 1. The air filter should not be installed, reverse-mounted or misplaced with each sealing gasket and rubber connecting pipe during installation, and ensure the tightness of each pressing. Use the paper dust cup air filter. For every 50-100 hours of work, remove the dust once. Use a soft brush to brush off the surface dust. If the working time exceeds 500 hours or it is damaged, it should be replaced in time. Use oil bath air filter, clean the filter element and replace the oil in every 100-200 hours of operation. If the filter element is broken, it needs to be replaced immediately, and pay attention to the addition of oil according to the regulations. 2. If the oil filter is not in time for maintenance in the diesel generator set, the filter element is clogged, the oil pressure is increased, the safety valve is opened, and the lubricating oil directly flows into the main oil passage, which will aggravate the wear of the lubricating surface and affect the service life of the diesel generator set. Therefore, the oil filter should be cleaned once every 180-200 hours of operation and found to be damaged. It should be replaced immediately to prevent impurities from entering the lubrication surface. When the generator set is used in season, the crankcase and each lubricating surface should be cleaned by mixing the oil, kerosene and diesel oil as washing oil. After the oil is released, the washing oil can be added for cleaning. Then, the diesel generator set runs at low speed for 3-5 minutes. , then drain the washing oil and add new oil. 3. For each fuel filter in the fuel supply system, every 100-200 hours of operation, the debris should be removed once, and the fuel tank and each oil pipeline should be thoroughly cleaned. When cleaning the filter element and seal, it should be especially careful to find damage and need to be replaced in time. During the seasonal transition, the parts of the entire fuel supply system should be cleaned. The diesel used should meet the seasonal requirements and require 48 hours of precipitation purification. Note: The three filters of air cleaner, oil filter and fuel filter are consumables. When used for more than 500 hours, they must be replaced with new ones. In this way, the service life of the diesel generator set can be better extended.

Advantages of Silent Type Diesel Generator Set 1. Beautiful appearance and reasonable structure; 2. Good sealing: rainproof, snowproof, dustproof, can work in harsh environments; 3. Good safety: fully enclosed box, made of 2mm steel plate; 4. The air in the box is smooth, the temperature is not too high, and the power of the unit is guaranteed; 5. Soundproof performance is good: the protective unit also has noise reduction performance, and the box is effectively noise-isolated, so that the unit can effectively reduce some noise during operation; 6. The high-frequency, medium-frequency and low-frequency PUR-type flame-retardant sound-absorbing cotton is used in the box to effectively reduce the different noises transmitted from the whole unit. 7. The EPDM type keel seal is used to seal the door joint. 8. The muffler adopts high-efficiency resistive muffler to effectively reduce the noise of the unit exhaust. 9. Good operability: The designer takes the people-oriented guiding ideology and fully considers the convenience and safety of the operator on the operation of the oil machine. 10. Lifting: If necessary, the unit is equipped with 4 lifting devices in order to facilitate the transportation in the field.

Basic operating procedures for Diesel Generator Sets 1. Preparation before starting. It is necessary to check whether the cooling water or antifreeze in the diesel water tank is satisfied before starting the machine. If it is missing, it should be filled up. Pull out the oil oil gauge to check whether the lubricant is missing. If it is missing, add it to the specified [quiet" scale line, and then carefully check the relevant parts for potential troubles. If the fault is found, it must be eliminated in time to start. 2. It is strictly forbidden to start the diesel engine with load. Before starting the diesel engine, be aware that the output air switch of the generator must be in the off state. After the diesel engine of the ordinary generator set starts, it will take 3-5 minutes of idle operation (about 700 rev / min). The winter temperature is low, and the idle running time should be extended for a few minutes. After starting the diesel engine, first observe whether the oil pressure is normal and whether there is any abnormality such as oil leakage or water leakage. (Under normal conditions, the oil pressure must be above 0.2 MPa.) If abnormalities are found, stop the maintenance immediately. If there is no abnormality, the diesel engine speed will be increased to the rated speed of 1500 rev / min. At this time, the generator display frequency is 50HZ and the voltage is 400V, then the output air switch can be put into use. The generator set does not allow long-term no-load operation. (Because the long-term no-load operation will cause the diesel fuel injected from the diesel injector to not completely burn, resulting in carbon deposits, resulting in air leakage in the valve and piston ring.) If it is an automatic generator set, there is no need to idle because the automatic unit is generally Equipped with a water heater, the diesel engine block is always maintained at 45C & ordm; the diesel engine can be powered normally within 8-15 seconds after starting. 3. Pay attention to observe the working state in operation. In the work of the generator set, there must be a special person on duty, and often pay attention to observe a series of faults that may occur, especially pay attention to changes in important factors such as oil pressure, water temperature, oil temperature, voltage and frequency. In addition, it should be noted that there is enough diesel fuel, such as fuel interruption during operation, and objectively causing the load to stop, which may cause damage to the generator excitation control system and related components. 4. It is strictly prohibited to stop with load. Before each stop, the load must be gradually cut off, then the genset output air switch is turned off, and finally the diesel engine is decelerated to idle speed for 3-5 minutes and then stopped.

Diesel generators have 5 major fuel-saving technical notes: 1. Install the inertia supercharger: Install the inertia supercharger on the diesel generator set, which can generally increase the power by 15% and the fuel consumption by 3% to 5%. 2. The returning oil pipe is diverted: the diesel oil return pipe is connected to the high pressure oil pipe, so that the oil returning to the low pressure oil circuit can ensure normal combustion, and the fuel saving effect is very remarkable. 3. Wrap the toilet paper on the filter element: Wrap 2 to 3 layers of absorbent paper on the diesel oil filter to improve the cleanliness of the oil and reduce fuel consumption. 4. Add foam plastic air filter: In the air filter two-layer filter, add a layer of 8~20mm thick foam with good air permeability to improve the filtration effect, keep the fuel burning normally and reduce fuel consumption. 5. Use the fuel-saving and smoke-reducing device: fix the fuel-saving and smoke-reducing device vertically in the front end oil passage of the fuel injection pump, and connect the DC power supply. Used on diesel generator sets, smoke reduction is significant. It not only reduces environmental pollution, but also saves about 5% of fuel.

Reasons for High Temperature in Diesel Generator Sets After systematic analysis, the main reasons for the excessive temperature of the diesel engine of the generator set are: 1. Diesel generator sets use hard water for a long time, and a large amount of scale is formed in the water tank and the waterway, resulting in poor heat dissipation. 2. the impurities in the water channel of the body and the cylinder head are deposited too much, so that the water circulation is not smooth, causing poor heat dissipation. 3. severely burned the engine oil, resulting in excessive carbon deposition and poor heat dissipation. 4. improper use of the operation. Start the diesel engine should first use the small and medium throttle to warm up for a period of time, can not suddenly increase the throttle, and increase the load, otherwise the diesel engine will work rough and the temperature will increase sharply. Or if the diesel engine is overloaded for a long time, it will also cause the diesel engine temperature to be too high. 5. The diesel engine is overheated due to the late supply of oil. 6. Immediately after the repair, the whole load should be put into operation, causing the moving parts to overheat or jamming due to the small gap. 7. The cooling water is insufficient, causing the diesel engine to overheat.

Maintenance method of Diesel Generator Sets 1. Change oil, diesel, bypass, water filter, oil and engine circulating water. 2. Clean or replace the air filter. 3. Disassemble the rocker cover and check the valve guide and T-plate. 4. Check and adjust the valve clearance. 5. Replace the upper and lower pads of the rocker arm room. 6. Check the fan and bracket and adjust the belt. 7. Check the supercharger. 8. Check the electrical circuit of the diesel generator set. 9. Check the circuit of the excitation part of the motor. 10. Check the connection line inside the instrument box. 11. Check the water tank and external cleaning. 12. Repair or replace the pump. 13. Dismantle the wear of the main shaft and connecting rod of the cylinder. 14. Check or adjust the electronic speed regulation working condition. 15. Inject the grease into the lubrication point of the diesel generator set. 16. Align the excitation part of the diesel generator set for dust removal. 17. Check the axial and radial clearance of the supercharger. If the deviation is excessive, it should be repaired in time. 18. Clean and calibrate the injector and fuel pump

The reasons for the power drop in the generator as follows: 1. The air filter is too dirty and the intake air is not enough; 2. The fuel filter unit is too dirty and the fuel injection amount is insufficient; 3. The ignition time is not correct; 4. The degree of insulation of the generator is also deteriorating. Due to the above factors, the output power of the generator set will become smaller, and the power requirements of the generator will not be achieved. At this time, the generator manufacturer experts proposed the following solutions: First, the new air filter must be cleaned or replaced. Replace or clean the diesel oil and water separator. Then adjust the ignition time. In this way, the power of the generator set may resume again, perhaps returning to the customer's calibration power requirements. In fact, diesel generator sets are like cars. Because they work by inhaling air, there are more dirt in the air. Therefore, after a long time, the air filter must be cleaned or replaced. In short, each generator set should be regularly maintained during use, so as to ensure that the power consumption of the generator set does not decrease, ensure the service life of the generator set, and regularly maintain the generator set, which not only can extend the life of the generator but also improve the life of the generator. The working efficiency of the unit.

After several years of using, the diesel generator set will have some minor problems, such as failure to start normally. The prerequisite for the normal operation of the diesel generator set is that the atomized diesel can be accurately and timely in the combustion chamber, and the compressed air in the combustion chamber should be reached. Sufficient temperature to catch fire and break out. Today, we analyze why there are no reasons why diesel generator sets cannot be started. 1. There is no oil in the fuel tank or the fuel valve is not open. 2. The oil system blockage of the fuel system causes the unit to not come to the oil. 3. There is moisture in the fuel and it is not easy to catch fire. 4. Air is introduced into the fuel supply system of the generator set to reduce or not supply oil. 5. The temperature in the combustion chamber and the cylinder is too low or the injection quality of the injector is not good, so that the fuel atomization is not good, and it is difficult to form a combustible mixture, so it is difficult to start. 6. The high pressure oil pump has insufficient oil supply and the oil supply pressure is too high or too low. 7. The unit injection time is too early or too late. 8. The generator set starts to run out of battery power, the controller is not energized, and the start relay is faulty. 9. The preheating is insufficient before starting, and the unit is in a low temperature state. 10. Diesel generators use fuel of the wrong type or grade. 11. The oil pump is faulty. 12. The unit starts to have insufficient battery capacity.

Diesel generator sets can be used in a wide range of industries, as a main power supply, backup power supply, emergency power supply! Here's a look at the specific application: 1. the main power supply These types of generator sets operate year-round, usually located in areas close to the power grid (or city power) or industrial and mining enterprises to meet the construction, production and domestic electricity consumption of these places. Because it invests in provinces and builds fast, it can supply power from its own network. In recent years, many countries have developed diesel generator sets in remote areas. At present, in areas where emergency development is relatively fast, it is necessary to meet the demand for diesel generator sets that are often used for short construction periods. Such generator sets generally have a large capacity. 2. backup power In the normal case, the power required by the user is supplied by the mains, and when the mains limit electric pull or other reasons interrupt the power supply, the generator set is set up to ensure basic production and life. Such generator farms are located in important power-using units such as industrial and mining enterprises, hospitals, hotels, banks, airports and radio stations with tight supply of electricity. In addition, in order to promote the construction of tourism development zones. Nowadays, many tourist areas in China have introduced diesel generator sets as backup power sources, ensuring the development of tourist attractions and the safe operation of facilities. 3. emergency power supply For the use of electrical equipment that will cause major losses or personal accidents when the mains supply is suddenly interrupted, emergency generator sets are often provided to provide emergency power to these equipment, such as fire protection systems for high-rise buildings, evacuation lighting, elevators, control systems for automated production lines, and important communication systems. . This type of generator set requires the installation of a self-starting diesel generator set with a high degree of automation.

The diesel generator set is the main backup power source produced by the manufacturing enterprise. The price of the diesel generator set is the diesel fuel. At present, with the continuous increase of the oil price, the oil is also rising. In order to reduce the cost of use, the most important thing is When using the generator set, the oil consumption of the engine oil should be reduced as much as possible to save oil. What are the fuel-saving methods for diesel generators? 1. Maintain the temperature of the cooling water of the diesel generator set at 45-65 °C. Increasing the temperature of the cooling water can increase the temperature of the generator body, which not only promotes more complete combustion of the diesel oil, but also reduces the viscosity of the oil, thereby reducing the resistance during exercise and achieving a fuel-saving effect. In addition, the selection of cooling water requires certain conditions. It is not advisable to use "soft water" of minerals, such as distilled water or rain water, and it is not suitable to use sewage or drowning. 2. Purify the area before using the oil. About 60% of the faults in the diesel generator set come from the fuel supply system, so it must be processed before adding fuel to the generator set. The method of starlight treatment is as follows: the purchased diesel oil is left to settle for about 2-4 days and can be used to precipitate about 98% of impurities. If it is used now, two layers of silk cloth or toilet paper can be placed at the fuel tank filter screen. . The purpose of processing the oil is to make the diesel generator set more fuel efficient. 3. Within the rated power, do not overload. When using the generator set, it is best to use it within the rated power. Do not overload it, otherwise it will not achieve the purpose of fuel saving. Overload operation not only affects the life of the generator set, but also greatly increases the fuel consumption. The general load rate is controlled at a reasonable level, and the load rate is between 50% and 80%. 4. Remove carbon deposits in time. During the combustion operation of the diesel generator set, the relevant components generate high temperature, so that the ash polymer adheres to the valve, the valve seat, the injector, the top of the piston, etc. If not removed in time, the fuel consumption will increase, which will affect the normal engine. Work, the general cleaning time is 4-6 months. 5. Increase the diesel pulley: Appropriately increase the diesel pulley, the pump speed can be increased under the condition of the diesel generator set running at a reduced speed, so that the flow and the lift are increased, thereby achieving energy saving. 6. Regular maintenance of the diesel generator set. When the engine is used for a long time, the generator will be worn normally. If the maintenance is improper, it will cause abnormal wear, which will cause the cylinder liner of the diesel generator to form a longitudinal line. The bore and piston side clearance will exceed the specified value, and the piston ring will support the corresponding force. Reduced, the phenomenon of scraping oil is not clean. Therefore, Starlight reminds everyone that it is necessary to carry out regular maintenance on the diesel generator set. 7, to ensure that the machine does not leak oil. Diesel generator oil pipelines often have loopholes due to uneven joint surfaces and gasket deformation or damage. 8. Maintain the best oil supply angle. If the oil supply angle is offset, the oil supply time will be too late and the fuel consumption will increase greatly.
