scoll compressor pumping

[sunilgavraskar]

anybody tell me how to check scroll compressors pumping?and how it is lossed?

[Grizzly]

Is this a new or existing installation?
Is It running? what amperage is it pulling.
What are the gauge pressures.
Is it 3 phase, because it is common.
To carry out a phase rotation check upon commissioning.
If it is running back-wards you can hear the difference.
etc etc.

Sunil,
The safest way to check scroll pumping is to check the suction/ discharge pressures of the system while runnning. Never test scroll in open Air as it would damage the bearigs and scroll sets.
