Huizhou Used Generator Recycling: Some Maintenance Methods

发表时间:2018-06-20 17:31:53 【 Popularity: 623Published time: 2018-06-20 17:31:53 [Large Middle Small]
The recycling of second-hand generators is currently limited to the following maintenance methods:
Inspection of the four leakage phenomena, surface, starting battery, oil and fuel of the unit;
Clean and improve the environment of the equipment room, and regularly replace the three filters;
Carry out no-load every month, and perform maintenance such as loading test machine every six months;
Use power monitoring to observe power quality parameters in real time.
Limitations of existing maintenance methods for recycling used generators :
The loading test in the existing maintenance is only the on-load test of the existing electrical equipment at the back end, which has certain risks and low power;
There is no scientific basis for replacing the three filters or after overhaul;
After replacing the three filters or after overhaul, there is no special load for loading the test machine, it is not clear whether it can achieve the intended purpose;
A large amount of carbon deposits from no-load test machines and low-power loading.

Second-hand generator recovery and repair case:
I. The load capacity of a central office in a postal district is reduced by 360KW. The power of the unit is 8 years. Due to the attention of the responsible person to the backup power supply, in order to ensure that the service system of the entire postal office is not interrupted when the mains power fails suddenly The system has a UPS backup power supply), the unit must be able to start normally, and the output must exceed the existing load of the post office. After loading the test machine, the unit's load capacity is only 210KW.
Failure analysis: After inspection, it is caused by excessive carbon deposits caused by long-term no-load test of the unit, which reduces the output power of the unit.
2. The load-carrying capacity of a mobile company is reduced. Due to the attention of the responsible person to the backup power source, the load of a mobile company has exceeded 300KW, and the power of the unit is 460KW. After 7 years of use, the unit can work normally after the power outage. After starting up, after loading the test machine, it was found that the load capacity of both units was reduced to 270KW and 300KW, respectively, and the control parts of the two units were widened, exceeding the standard.
Failure analysis: After inspection, it is caused by excessive carbon deposits caused by long-term no-load test of the unit, which reduces the output power of the unit.
Note: The diesel generator set will have different degrees of power reduction according to the environment of the machine room, the service life, inadequate daily maintenance, and replacement of equipment and components. This has important safety risks, and the diesel generator set has no load for a long time or Idle operation will cause carbon deposits, which will cause the engine output power to decrease, affect the output of the entire unit, and even cause the illusion of normal operation. Once the load is actually loaded, a major failure of the diesel generator set cannot operate normally. Formation of carbon deposits: Because the temperature of the combustion chamber is too low, it is impossible to completely burn the fuel, which will cause carbon deposits, which will block the nozzle holes and piston rings of the fuel injectors, and there will be "black oil" overflow from the exhaust pipe. The valve may get stuck. Some unburned diesel will wash the lubricating oil on the cylinder wall and dilute the oil in the crankcase, causing all the running parts in the engine to suffer from poor lubrication. http://hzbxx.cn/
