Analysis of common faults of diesel generators
At this stage, the continuous improvement of my country’s scientific and technological development level has givenDiesel generatorsManufacturing and performance optimization provide important technical support. In practice, in order to achieve safe use of diesel generators and maintain their good functional characteristics, it is necessary to analyze common faults related to them and find practical and effective countermeasures to solve them. .
1. Unable to start normally
When a diesel generator fails to start normally during application, it will reduce the application level of this type of equipment and increase the incidence of diesel generator failures. In practice, the reasons that make it difficult to start normally include: 1. Due to the mixing of the fuel system There is air leakage, there are blockage problems in the fuel pipeline, abnormal operation of the fuel pump, etc., which will cause the diesel generator fuel system to malfunction and affect the operation quality of the equipment; 2. When the battery power is insufficient, the fuel injection pump rod, etc. cannot work normally. Under the influence of other factors, electric starting system failure may occur, thereby increasing the operating risk of the diesel generator; 3. Under the influence of various influencing factors such as operating when the ambient temperature is too low, insufficient lubrication between bearings, valve leakage, etc. It will pose a potential threat to the operating quality of the diesel generator, restrict the improvement of its safe operation level, and affect the working performance of this type of equipment.
2. The exhaust smoke color is abnormal.
When the exhaust color of a diesel generator is abnormal during operation, it will face certain operational risks and indirectly increase the probability of failure. The specific manifestations are: 1. Suffering from overload and atomization conditions Poor fuel injection and lack of uniformity of oil volume cause black smoke to appear in the exhaust of the diesel generator, posing a potential threat to its safety performance; 2. Poor fuel atomization in the injector and insufficient diesel combustion. Under the influence of abnormal operation of individual cylinders and the reduction of the application quality of the cylinder gasket, the diesel generator exhaust will emit white smoke, posing certain hidden dangers to its application; 3. When the oil surface temperature is different from the actual requirements If the oil ring is not consistent and the oil ring is stuck, blue smoke will emit from the exhaust of the diesel generator during operation, thereby reducing its safe operation level.
3. Other common faults
Based on the application research of diesel generators, it is also necessary to understand its common faults in these aspects: 1. Under the influence of abnormal oil pressure or no pressure, the diesel generator will not work properly, affecting its functional characteristics and utilization value, etc. It causes safety issues in the application of this type of equipment, making it difficult to meet the high-efficiency operation requirements of diesel generators, and the related power generation effect will also be affected to varying degrees; 2. When the valve chamber and transmission gear make abnormal noises, the valve clearance and decompression When the structural condition is not good, the diesel generator will make abnormal noises, which will affect its operation quality and performance to varying degrees; 3. When air enters the water pipe, the water temperature in the diesel generator will be too high. High phenomenon, coupled with the reduced working performance of the radiator, the delay in adding cooling water and other factors, will cause the diesel generator to run into trouble. Targeted solutions need to be found to deal with it, so as to provide this type of equipment with It lays the foundation for improving the safe operation level, meeting the usage requirements of diesel generators, and extending the life cycle of equipment.
