Hi,

Just come across this site and wondered if anyone could help. I have a Mycom 2520 two stage screw compressor core packaged by other company operating on natural gas.
The problem is on a start up it keeps losing the oil differential pressure, but this only seems to happen when the discharge pressure reaches 14bar (normal output 23 bar). The compressor has recently had a rebuild with new bearings and operated ok up until now.

Any ideas what could be causing the oil differential pressure to drop? (new filters installed)

Thanks in advance for any suggestions
