Diesel generator set in the use of the process sometimes there will be a variety of failures, a variety of phenomena, the causes of failure are also diverse, a fault may occur a variety of abnormal phenomena. No matter where the generator set failure will cause the diesel generator set can not work normally. Therefore, the judgment of the fault is to judge which system or component is caused by what reason according to the process of occurrence in the complex and varied phenomena. For different fault phenomena, different methods should be flexibly used, starting from the working principle and structure of the diesel generator set. Through careful observation and correct analysis to find the right way to deal with the problem, eliminate the fault.
There are many ways to judge the fault of diesel generator set. At present, the most used are partition method, comparison method, verification method and instrument inspection method.
1. Partition method
The partition method is to stop the work of a single cylinder of the diesel engine or stop the injection of several or even all cylinders one by one, and observe the changes in the working state of the diesel engine before and after stopping the injection. Using this method to check the working condition of each cylinder, especially to check the exhaust color of each cylinder is the most effective.
2. Comparative method
Comparative method is widely used. After the failure of the diesel generator set, if there is doubt about a part or system, it can be replaced with a good quality part or a normal system, and observe whether the fault phenomenon is eliminated. If the fault disappears, it proves that the fault occurred in the component or system.
3. Verification method
The verification method refers to the tentative adjustment or disassembly based on the known cause of the fault to check the correctness of the past analysis, so as to find the fault.
4, instrument inspection method
Instrument inspection method refers to the use of instruments or instruments to test the diesel generator set, find out the hidden trouble, and understand the performance and condition of the unit.
Master the above methods, you can be a good judge of the diesel generator set in the use of the process of failure.
