I would like to ask for advice: In my factory’s hydrogen compressor model 4LW-18/0.5~6, after replacing the first and second stage valves as well as the piston guide valve, the exhaust pressure on the first stage remains high. It worked fine when nitrogen was used, but as soon as hydrogen was used, the exhaust pressure on the first stage became high; after 2 or 3 hours, the compressor stopped operating. What could be the reason? Are there any good solutions? How to perform maintenance? Looking forward to your reply very much! Thank you so much! ! ! ， ， -
A high first-stage exhaust pressure indicates that the first stage is strong; could there be a problem with the subsequent stages?
Make sure the valve disc of the primary exhaust valve isn’t installed incorrectly! Also, there’s what was mentioned upstairs!
Check whether the secondary air valve is leaking and whether there is a return line; if so, inspect the valve
First, the compression ratio is different when testing with nitrogen compared to hydrogen; it is best not to use nitrogen for testing. The pressure at the second stage is high; just because a new second-stage gas valve has been installed doesn’t mean it’s of good quality. Check the second-stage intake gas valve.
