柴油机发电机组发生故障是因为什么?

故障一、油路不供油
Fault 1, no oil supply.
多为燃油箱无燃油、油面过低、油管裂损进气、连接件松脱、燃油中进水、燃油滤清器及溢流阀堵塞、滤网堵塞等。
Most of them are non-fuel tank, low fuel level, cracked intake of tubing, loose connector, water intake in fuel, fuel filter and relief valve plugging, filter screen plugging, etc.
油路:柴油机燃料供给系从柴油的供给线路上看可分为:低压油路、高压油路和回油油路。
Oil circuit: Diesel fuel supply system from the diesel fuel supply line can be divided into: low-pressure oil circuit, high-pressure oil circuit and return oil circuit.
低压油路:从柴油箱到喷油泵这段油路,油压是由输油泵建立的。高压油路:从喷油泵到喷油器这段油路,油压是由喷油泵建立的。回油油路:输油泵的供油量比喷油泵的出油量多,一般大3~4倍,多余的燃油经滤清器或喷油泵上的限压阀和回油管流回输油泵的进油口或直接流回柴油箱。喷油器工作间隙泄漏的极少数柴油也经回油管流回柴油箱。

Low pressure oil circuit: from the diesel tank to the fuel injection pump section, the oil pressure is built by the oil pump. High pressure oil circuit: from the fuel injection pump to the fuel injector, the oil pressure is built by the fuel injection pump. Fuel return circuit: The fuel supply of the fuel pump is 3-4 times larger than that of the fuel injection pump. The excess fuel flows back to the inlet of the fuel pump or directly back to the diesel tank through the pressure limiting valve on the filter or the fuel injection pump and the return pipe. A very small number of diesel oil leakage from the fuel injector also flows back to the diesel oil tank through the return pipe.
故障二、喷油泵不能产生高压油雾
Fault two, fuel injection pump can not generate high-pressure oil mist.
喷油嘴阀卡或堵塞、喷油泵柱卡滞、出油阀密封不严、供油调节杠杆功能不良、输油泵工作失效、有关部件损坏等,均会导致喷油泵不能产生高压油雾。
Blockage of nozzle valve, stuck of injection pump string, improper sealing of oil delivery valve, poor function of oil supply regulating lever, failure of oil delivery pump and damage of related parts all lead to high pressure oil mist.
故障三、喷油定时不准
Fault three, fuel injection timing is not allowed.
柴油机有推杆滚轮及凸轮磨损、喷油泵驱动连部件损坏及调校不当等原因。
The diesel engine has the reasons of putter roller and cam wear, fuel injection pump drive parts failure and improper adjustment.
