Liquid entrapment issue in reciprocating compressors
Thread Content
Everyone is aware of the danger posed by liquid in reciprocating compressors, but one thing that has never been clear to me is why the liquid in the cylinder does not exit the cylinder along with the exhaust gas
A small amount can be discharged; the liquid is incompressible within the cylinder, which can cause liquid slugging.
Liquid in the cylinder generally refers to pure liquid water that comes from the previous separator or leaks from the cylinder jacket; it will only be discharged through the outlet valve after being compressed, and the compression process is essentially the process of collision with the cylinder walls. Only a small portion of the liquid deposited at the bottom of the cylinder is carried away with the gas.
I’ve learned it. Then could you explain how to handle it through various process measures during operation?
The gas inside the compressor cylinder is first compressed, and then discharged through the exhaust valve. During this process, the gas does not flow as it would in a pipe; therefore, when the exhaust valve opens, not all of the liquid is carried out.
