柴油发电机组发生散热器溢流原因 Generator Radiator Overflow

柴油发电机组发生散热器溢流原因可能是喷油器水封套密闭不严或开裂。喷油器与气缸盖中间有隔水套。防水套管与水道联接，并用橡胶密封圈密闭。长期操作后，气缸盖水套与气缸盖连接处会因为老旧化而产生细小裂痕，或因橡胶老旧化而密闭不好。燃烧后的混合物通过微小的缝隙渗入水道，使散热器中的水外溢。

The reason of radiator overflow in generator may be that the water jacket of the injector is not tightly sealed or cracked. There is a water barrier. The waterproof casing is connected to the waterway and sealed with a rubber sealing ring. After long-term operation, the connection between the cylinder head water jacket and the cylinder head will have small cracks due to aging, or the sealing will not be good due to the aging of the rubber. The burned mixture seeps into the water through tiny gaps, causing the water in the radiator to overflow.

冷油器问题可能有2种状况：

The oil cooler may have 2 problems :

1.散热器芯有裂痕或砂眼；

The radiator core has cracks or blisters;

2.散热器芯与缸体油道接口处密封胶圈不严实。这样子，油便会进到水内，过多的油进到水之后从散热器中外溢（这种易于分辨，由于有机油会随水从散热器中外溢，油只能越来越少而并不会质变）。散热器的下水管道室由多个管道联接。假如由于操作不当，散热器积垢较多,管道易于堵住；柴油发动机高速旋转时，部分水经过水泵进到小循环，另部分进到散热器给水室。可是，由于配管道堵住，水从给水室外溢。在此，分别触摸散热器的上方和下方时，会看到有显著的温度差异。拆装时，只需拆装散热器并疏通下方配管道即可；或在散热器里加醋，让柴油发动机运行5分钟，随后换水。经过几次循环，散热器基本可以清洗干净。

The sealing rubber ring at the interface between the radiator core and the oil passage of the cylinder is not tight. In this way, the oil will enter the water, and if too much oil enters the water, it will spill out of the radiator (this is easy to distinguish, because organic oil will spill out of the radiator with the water, and the oil can only become less and less. It will not change in quality). The sewer chamber of the radiator is connected by a plurality of pipes. If due to improper operation, the radiator is more fouled and the pipeline is easily blocked.When the engine runs at high speed, part of the water enters the small circulation through the water pump, and the other part enters the radiator water supply chamber. However, due to blockage of the distribution pipes, water overflowed from the water supply room.At this time, when you touch the top and bottom of the radiator,you will feel a significant temperature difference. When disassembling, just disassemble and assemble the radiator and unblock the pipes below; or add vinegar to the radiator, let the engine run for 5 minutes, and then change the water. After several cycles, the radiator can basically be cleaned.
