The existence of a quality generator maintenance problems. "Small pieces of" good and bad do not pay attention, because of the "small" lost "big" lead to failure increases. When imported diesel generator generator maintenance repair work, some maintenance personnel are often only concerned about maintaining pumps, fuel pumps and other components, but they ignore all kinds of instruments, such as "a small piece" of maintenance. They believe that these "little pieces" do not affect the mechanical work, even if damage does not matter, as long as you make do with mechanical active. I do not know exactly what these "small pieces" lack of maintenance, resulting in the occurrence of early mechanical wear and shorten life. Equipment such as oil filters, and air filters, hydraulic oil filters, water temperature, oil temperature, oil pressure gauge, sensors, alarms, filters, grease fittings, oil return fitting, cotter pins, fans wind shield, drive shaft bolt locking plate, etc., which this "small pieces" is the device is working properly and maintenance essential, vital to extend the life of machinery, such as pay attention to maintenance, often "because of a small loss big ", leading to equipment failure. The main way to determine the fault current diesel generator set is used more cut off, comparison, verification methods and instrumentation check method. 1. Partition method. Off method is to stop a single cylinder diesel engine work or stop by one of several or even all cylinder fuel injection, diesel and stopped to observe the change before and after the injection. Check each cylinder work with this method, in particular to check the color of each cylinder exhaust most effective. 2. Comparative Law. Comparison method used more commonly, after diesel generators fail, or if there is a part of a system which suspected generator repair, replacement or a part of a good quality of a normal system, to observe whether the fault is eliminated, if Symptom disappeared, prove fault occurred in this part or the system. 3. Verification method. Verification method is a known cause of the failure, by a tentative adjustment or removal, to check the correctness of the analysis in the past Cummins generator maintenance, and to find fault lies. 4. Instrument Inspection Act. Instrument inspection method is the use of the instrument or instruments for diesel generator sets for testing, to find hidden faults, understand the performance and condition of the unit. In short, for different symptoms, Jiang Su Haixing Power reminded to make flexible use of different methods of troubleshooting maintenance of diesel generators, diesel generator sets from the principle, structure start to find solutions to problems. The following different types of diesel generator sets for analysis Symptom aim is to make diesel generator set operator in the event of the same type symptoms, shorten the time to find fault, timely troubleshooting.
