Description
Type DPSM-690 is used as a safety device on pressure
lubricated refrigeration compressors, where under any
operating conditions the lubricating oil pressure has to be kept higher than the suction pressure or crankcase pressure.
The bellows marked OIL is connected to outlet side of
compressor or at discharge from crankshaft lubrication
system, and measures the lubricating oil pressure P1.
Bellows marked LP is connected to the compressor
crankcase and measures the crankcase pressure P2.
Differential Pressure (P1–P2) is the pressure available for
the lubrication system. If during start up, differential pressure
fails to reach the set value, or if during operation differential
pressure falls below the set value, the control device breaks
the circuit to compressor motor after an allowable time delay.
Once the circuit is broken, it has to be reset manually by
pressing the reset knob.
