Compressor cylinder cooling water temperature
Thread Content
Gentlemen, I noticed during the operation that the compressor is designed to keep the temperature of the cooling water in the cylinder 5-6°C higher than the suction temperature. I would like to ask what the reason for controlling this temperature is – why must it be 5-6°C higher than the suction temperature? Thank you
Prevent gas from condensing and forming liquid.
Is there a standard for this as well? I really hadn’t paid attention to it before. Now that you mention it, and after reading the replies on floor 2, it seems quite reasonable. I’ll wait for the replies from below, hehe
It mainly depends on the composition of the medium; natural gas and media containing hydrocarbons all have such requirements
The sofa is the right choice; if there’s liquid involved, it can damage the air valve
This is determined based on the operating conditions of your compressor; not all compressors are the same in this regard. For easily liquefiable gas media, the temperature is kept higher to prevent liquid accumulation in the suction state.
This is probably not universal; the compressors in our factory don’t have such a restriction. Logically, it’s better to keep the water temperature as low as possible, as this can increase the compressor’s air delivery capacity and improve efficiency. Moreover, the temperature of the circulating water in a given area varies significantly between summer and winter
I’ve never seen this in the standard specifications. Moreover, the compression process itself is also a process of temperature increase; temperature is proportional to the power of pressure. Hehe, so the explanation that there is water in the gas valve isn’t quite correct either
