I have an engine
driven frig compressor
, SANDEN 501.
Recently the system had a leak and emptyed all the gas ...found it, now fixed. System was regassed by a local frig mechanic
and now after about an hours running, there's a terrible graunching noise
coming from the compressor
The belts are OK, the mounts are good..I know its the compressor, 'cos if I relase the clutch
It just occurred to me that maybe the system has too much gas in it (overcharged) and after an hour liquid refrigerant is getting into the compressor - it can't compress a liquid - and therefore the noise.
Any frig experts out there with some ideas ?
If this is the problem, can I just release some gas out of the Shraeder valves to cure it ??
