Seeking help: The temperature of one of the primary air valves in a three-stage reciprocating compressor has suddenly increased
Thread Content
One of the tubes saw its temperature rise suddenly from 110 degrees to over 120 degrees; after that, the temperatures of the other three tubes also increased. After two days, everything returned to normal. During this period, neither the volume of gas nor its composition changed, and the intermediate heat exchanger was found to be functioning properly. What caused things to return to normal after two days?
First, you need to clarify what you mean by \"one temperature\" – is it a mercury thermometer? A metal thermometer? If it is a digital display for the temperature sensor, this phenomenon requires shutting down the equipment for inspection and maintenance. This kind of phenomenon can occur in both piston rings and valve plates. The most likely explanation is that some foreign object was pressing against the valve disc, and once it fell off, things returned to normal. So it should be disassembled for inspection and maintenance. For reference.
Thank you for your reply. By \"temperature,\" I mean the temperature of a exhaust valve
The temperature of one exhaust valve rises, and the temperatures of the other three also increase one after another. It’s unlikely that there’s a problem with the temperature detection unit; since it has returned to normal, it can be monitored. If the same phenomenon occurs, check the cooling water pressure of the heat exchanger as well as the pressures at the inlet and outlet of the compressor. The gas volume has not changed; it’s possible that it has already reached the device’s design value: lol
If the exhaust temperature is high, it might be because the valve plates are dirty or there are foreign objects stuck in them; the problem goes away after some time, probably as the foreign objects get removed from the valve plates. Your question isn’t clear enough – what are the other temperatures? Generally, a high exhaust temperature can also lead to a high intake temperature; a high temperature at the first stage of exhaust processing can cause a higher temperature at the second stage of intake, which in turn leads to a higher exhaust temperature at that second stage. . . If there is no cooling or the cooling effect is poor (changes in the inlet temperature of the cooler prevent achieving the desired cooling effect in the process)
It seems that the extremely high temperatures of the four exhaust valves are caused by foreign objects getting stuck in the exhaust valve plates, thereby affecting the return air flow
