The valve seat of the second-stage inlet valve in reciprocating compressors is prone to cracking
Thread Content
Hello, dear sea friends: Our reciprocating compressor has been in operation for nearly three years, but recently the valve seats of the inlet valves on the second stage start to crack after just a few days of use. I’m not sure what’s causing this I would appreciate everyone’s advice.
Check the material to see if there are any casting defects
Broken valve seat? What tremendous force must that have been – it must have caused the valve disc to break, right?
A broken valve seat usually means that the valve is moving inside, creating a gap; it’s definitely because the valve cover wasn’t installed properly or the set screws weren’t tightened enough, :)
Is it the valve seat? It’s more likely that the valve disc is broken; if it’s the valve seat, it should be made of cast iron, right?
It is the inlet valve seat, made of 3Cr13 material
