Hello.
I’d like to get a piece of advice about my situation. I have at the plant the refrigeration compressor Mycom FM 160. Thing is that the compressor works constantly with load 100% even if it gets signal to unload. The slide valve stays without moving towards unloaded side. All oil channels were inspected during overhaul of the compressor; oil was changed. The unload/ load valves and solenoid coils were replaced. I checked tension on the coils during work- it’s okay. The compressor worked quite well during two days after overhaul but now… by the way, it had started to work without unloading before its repairing.
Moreover, I can see increasing of discharge temperature.
I would appreciate any help and advices about it.
Thanks.
