Method for judging diesel generator set failure

Diesel generator sets sometimes have various faults during their use. There are various kinds of phenomena, and the causes of faults are also various. A fault may cause various abnormal phenomena. No matter where the generator set fails, the diesel generator set will not work properly. Therefore, the judgment of the fault is to judge from the intricate and varied phenomena, according to the process of occurrence, which system or component is caused by the fault. For different fault phenomena, different methods must be used flexibly. The working principle and structure of the diesel generator set start with the careful observation and correct analysis to find the correct treatment of the problem and eliminate the fault.

There are many ways to judge the failure of diesel generator sets. At present, the partitioning method, comparison method, verification method and instrumentation inspection method are mostly used.

1, partition method

The partition method is to stop the single cylinder operation of the diesel engine or stop the injection of several or even all cylinders one by one, and observe the change of the working state of the diesel engine before and after stopping the injection. Use this method to check the operation of each cylinder, especially to check the exhaust color of each cylinder is most effective.

2, comparison method

The comparative method is more common. After a diesel generator set fails, if there is any doubt about a component or system, you can change a good quality component or a normal system to see if the fault is eliminated. If the fault disappears, it is proven that the fault occurred in this component or system.

3. Verification method

Verification is the exploratory adjustment or disassembly based on known causes of failure to check the correctness of past analyses to identify the fault.

4, instrumentation inspection method

Instrumentation inspection refers to the use of instruments or meters to test diesel generator sets, identify hidden troubles, and understand the performance and condition of the unit.

By mastering the above methods, it is possible to judge the failure of the diesel generator set during use.
