Diesel generator set is one of the indispensable and important equipment in modern life. However, due to the long-term operation and the influence of various external factors, diesel generators may encounter various failures. This article will analyze the common faults of diesel generator set in detail, and provide solutions and countermeasures to help users better maintain and manage the generator set.
First, fuel supply problem
1. Fuel pump failure: The fuel pump is a key component that transfers fuel from the fuel tank to the engine combustion chamber. Common faults include fuel pump seal failure, fuel pump internal parts wear and so on. The solution is to check and maintain the fuel pump regularly and replace the worn parts in time.
2. Fuel filter blockage: The main function of the fuel filter is to filter impurities and pollutants in the fuel. If the filter is blocked, it will lead to insufficient fuel supply and affect the normal operation of the generator set. The solution is to replace the fuel filter regularly to ensure the cleanliness of the fuel.
3. Fuel quality problems: The use of inferior fuel will lead to incomplete engine combustion, carbon accumulation and other problems. The solution is to choose high-quality fuel and clean the fuel system regularly.
Two, ignition system problems
1. Spark plug failure: Spark plug is an important part of the ignition system, used to generate sparks to ignite fuel. Common faults include spark plug wear and excessive electrode gap. The solution is to check and replace the spark plug regularly.
2. Ignition coil failure: The ignition coil is a key component in the ignition system, responsible for generating high voltage current to supply the spark plug. Common faults include coil insulation damage and coil internal faults. The solution is to check and replace the ignition coil regularly.
3. Ignition control module failure: The ignition control module is the electronic equipment that controls the ignition system. Common faults include circuit short circuit, circuit break, etc. The solution is to check and maintain the ignition control module regularly.
Three, cooling system problems
1. Coolant leakage: Coolant leakage will cause the engine to overheat, affecting the normal operation of the generator set. The solution is to check the cooling system regularly, repair leaks, and replenish the coolant.
2. Water pump failure: water pump is a key component in the cooling system, responsible for circulating coolant. Common faults include pump bearing wear, impeller damage and so on. The solution is to check and maintain the pump regularly and replace the worn parts in time.
3. Radiator blockage: The radiator is a cooling device in the cooling system, which is used to dissipate the heat generated by the engine. Common faults include heat sink blockage and heat sink corrosion. The solution is to clean the radiator regularly to ensure good heat dissipation.
Four, lubrication system problems
1. Oil leakage: Oil leakage will lead to increased wear of engine parts and affect the life of the generator set. The solution is to check and repair oil leaks regularly and replenish oil.
2. Oil filter blockage: The main function of oil filter is to filter impurities and pollutants in oil. If the filter is blocked, it will affect the flow of the oil and the filtration effect. The solution is to change the oil filter regularly.
3. Lubricating oil pump failure: Lubricating oil pump is a key part of the lubrication system, responsible for supplying oil to each lubrication point of the engine. Common faults include pump body wear, pump shaft fracture and so on. The solution is to check and maintain the lubricating oil pump regularly.
Fifth, Electrical system problems
1. Battery failure: The battery is an important device for starting and powering the generator set. Common faults include low battery power and battery corrosion. The solution is to check the battery status regularly and replace the aging battery in time.
2. Generator winding failure: generator winding is the core component of the generator, responsible for generating electrical energy. Common faults include winding short circuit, insulation aging and so on. The solution is to check and maintain the generator windings regularly.
3. Control panel failure: The control panel is the operation and monitoring center of the generator set, responsible for controlling the start and stop of the generator set and parameter adjustment. Common faults include circuit failure, display damage and so on. The solution is to check and maintain the control panel regularly.
Six, exhaust system problems
1. Exhaust pipe blockage: exhaust pipe blockage will lead to poor engine exhaust, affecting the performance of the generator set. The solution is to clean the exhaust pipe regularly to ensure that the exhaust is smooth.
2. Turbocharger failure: Turbocharger is an important part of diesel engine, responsible for increasing air intake and improving combustion efficiency. Common failures include turbine blade damage and turbine bearing wear. The solution is to check and maintain the turbocharger regularly.
3. Exhaust gas pipeline leakage: exhaust gas pipeline leakage will cause the pressure of the exhaust system to drop, affecting the performance of the generator set. The solution is to check the exhaust pipe regularly and repair the leak point.
Vibration and noise problems
1. Engine imbalance: Engine imbalance will lead to increased vibration of the generator set, affecting the stability and life of the equipment. The solution is to check and balance the engine regularly.
2. Fan fault: The fan is a key component in the cooling system and is responsible for heat dissipation. Common faults include fan blade damage and fan bearing wear. The solution is to check and maintain the fans regularly.
3. Loose base: Loose base will cause vibration and noise of the generator set, affecting the stability of the device. The solution is to check and tighten the base regularly.
Solutions and strategies:
1. Regular maintenance and maintenance of the generator set, including replacing the fuel filter, oil filter, etc.
2. Pay attention to the quality of fuel and avoid using inferior fuel.
3. Regularly check and replace the key components of the ignition system, such as spark plugs, ignition coils, etc.
4. Check the cooling system regularly to ensure the normal circulation of the coolant and the normal operation of the pump.
5. Regularly check and replace the key components of the lubrication system, such as oil filters, lubricating oil pumps, etc.
6. Check the electrical system regularly, including the battery level and the state of the generator windings.
7. Regularly check the exhaust system, clean the exhaust pipe and check the working status of the turbocharger.
8. Regularly check the vibration and noise of the generator set, adjust and repair in time.
Common failures of diesel generator sets involve many aspects, including fuel supply, ignition system, cooling system, lubrication system, electrical system, exhaust system, vibration and noise. Through regular maintenance and maintenance, as well as timely troubleshooting, the normal operation and long life of the diesel generator set can be ensured. Users should take appropriate solutions and coping strategies according to the actual situation to ensure the reliability and stability of the generator set.
