Failure phenomenon: The temperature of the pump body of the generator seal oil vacuum pump reaches 85 ℃ during operation.
1), the filter screen of the generator seal oil vacuum pump is blocked
2) The outlet pipe of the generator seal oil vacuum pump is blocked
1), replace the filter screen of the generator sealing oil vacuum pump
2) Check the outlet pipe of the generator seal oil vacuum pump. It was found that the pipe exhaust port was not insulated on the roof of the plant, and the pipe was frozen at the outlet, resulting in poor exhaust. Afterwards, saw the pipe with a bow at a slope above the 13.7-meter platform for temporary exhaust. In minor repairs, connect the pipeline to the inlet pipeline of the seal oil discharge fan.
Results after treatment: The pump body is operating normally.
1) In winter, the inspection work should be strengthened, and if there is ice at the exhaust port, it should be dealt with in time.
2). The oil level of the sealing oil vacuum pump should be checked in time. If the oil level is low, refill the oil immediately.
