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 generally where there is a generator repair, after the diesel generators fail, if there is suspicion of a component or system which, a good quality replacement parts, or one normal system, to observe whether the fault is eliminated, if fault disappears, prove fault occurred in this part or the system. 3. Verification method. Validation is the reason for the failure is known, through exploratory adjustments or disassembly generator maintenance, to check the correctness of the analysis in the past, 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 generator maintenance, for different symptoms, Jiang Su Haixing Power remind To utilize different methods of troubleshooting generator maintenance company, the principle of the diesel generator set from the structure to start finding 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. Towel over the winter and start diesel generator when the main operator in the winter diesel starting to do the following: - is to ensure that the oil is good; the second is to ensure that the battery capacity and power f, such as 135 series diesel generator sets generally make Chuan 6Q-195 batteries in the winter can be replaced with 6Q-210 or larger capacity most 12V battery, because the diesel engine starting torque capacity and by the quality of the body of the starter battery Xiang Ren dagger of the decision; the second is to sweep the diesel injectors Pedestrian footwall car; four is the intake valve, vacuum valve start playing BU; five is the cooling water is heated to ensure that the diesel engine is in state Lin bundle wrapped in cloth. 5. After the diesel generator set powered diesel power fast start is not allowed to sweep group after starting, warm-up and have a diesel engine lubrication process, or after the end of the process to be used before the normal power supply. Preheat and lubrication process is generally divided into three kinds of time required for each different, which generally require low-speed warm-up and lubricating 5min, speed needs 5-8min, speed needed to be water temperature, oil pan after about JU50 ℃ before normal power supply. After sweeping diesel power generation group just starting, power and lubrication during the warm-up, easily lead cylinder diesel engine, the cylinder head and the body to produce cracks cracks.
