It's the 1st stage cylinder we have trouble with. We have tried switching the valves and the problem continued. I'm pretty sure we can only really unload the head end on that machine. No we do not have HE clearance pockets, sorry forgot to answer that question. We have pressure transmitters...

We remachined the valves yesterday
However the compressor is still running a bit hotter than the other one. We ran it this morning at full load for a few minutes and we had to cut it to half-load because of...
We have a program that calculates the compression ratios. It reads 3.34 for the CE and 3.30 for the HE for the machine that's running hot. On the other machine its 3.42 for both HE and CE. It's an older style Cooper Jm-6 compressor. Do the ratios correlate with the machine running hot?
On our first stage of our hydrogen compressor..the head end discharge valves stay much hotter than the crank end discharge valves. We have 2 similar compressors that have this problem. There is no difference in the suction valves. the head end discharge valves run about 305 degrees on the...
