Greetings

Anyone here that has any "exploded view" or cutaway drawings of this compressor?

I have the installation & operation manual, but I don't have any drawings.

Been 25 years since I last saw a Hall mono screw and that was a small HS2020 or something.


Better yet if anyone has operated one, I'm having some issues with a brand new plant.

RSW system with on demand oil pump.

OP sensor is mounted on the side of the compressor and whenever the oil pump starts, the pressure on this sensor starts oscillating between 7-15 bar, however the sensor on the pump outlet (OPF, between oil pump and oil filter) is dead stable.

The pump is on demand, because it's OP minus LP, so once it gets load the differential pressure is enough.

I'm left with the suspicion that there may be either an internal non return valve on the oil port, or the compressor is somehow flooded with oil and gulping it out, kinda like an Howden XRV at 2000rpm where it's basically an oil pump

Amps and KW readings are dead stable too.

any and all input would be greatly appreciated
