The reciprocating compressor does not have sufficient discharge volume
Thread Content
After inspection, it was found that one intake valve spring had lost its tension; after replacing the spring and reinstalling everything, the distance between the unloader rod and the intake valve lift limiter was 60–80 units. The question is: could insufficient air flow be related to the issue with the distance between the unloader rod and the valve lift limiter? Also, what should be the distance between the ejector rod and the valve lift limiter?
First, measure the temperature of each gas valve; if the temperatures are normal, then it’s necessary to check the piston rings. For the clearance of the unloader rod, we have reserved 1–2 mm based on the stroke of the rod
Is there a problem with the compression ratio? What is the flow rate? By how much has the displacement decreased – by more than half or not much? How many stages of compression are there? Is it not sufficient even with the reflux valve closed? What is the exhaust temperature? What is the temperature of the valves and the cylinders? Is there any noise? What is the load level? It would be best to describe the current problems in detail so that I can help you. Is your unloader capable of variable adjustment, or does it only have settings at 0%/50%/100%? Under what condition of the unloader does the air volume become insufficient, and by how much?
Thanks. I checked each one one by one; it’s a single-cylinder compressor
Check the piston rings, valves, and unloader
