Some time ago, the compressor stopped operating; let’s analyze what could be the reason. At 11 o’clock, pump A in the ammonia tank area (with variable frequency control) suddenly stopped working. Another pump, B (without variable frequency control), was started at that time. An electrical inspection showed that there was no problem with pump A in the afternoon. At 3 p.m., pump A was tried out again, and when load was applied, both pumps A and B stopped operating simultaneously； At the same time, the lubricating oil pump shared by the syngas compressor and the chiller stopped operating, and the backup pump did not start automatically, which caused the syngas compressor and the chiller to shut down. Upon checking the power distribution room, it was found that no power was being supplied; after resetting the system, the lubricating oil pump could be started again. The electricity supply for the ammonia pump and the lubricating oil pump is not from the same circuit, and none of the other pumps have stopped working
There must be a problem with the control loop for this phenomenon! Please check the processing!
The electricity supply for the ammonia pump and the lubricating oil pump is not part of the same control circuit; how can that cause a problem?
What do you mean by no power being supplied?
If power is not supplied, the OFF light on the electrical distribution cabinet will light up, indicating that the circuit for the lubricating oil pump has lost power; as a result, the lubricating oil pump stops working
