In refrigeration system，lubrication system must be kept in a certain oil pressure in order to get well lubrication for every part.If the oil pressure is too low，compressors will happen“Cylinder sticking”for losing oil in normal running or starting，even destroy bearing pad of the compressor.
The differential pressure control receives the signal of discharge pressure from lubricating oil pump and suction pressure from compressor.And it maintains the two pressure in a certain differential range.When the difference is lower than the setting one，the switch automatically cuts the compressor circuit off to stop running.
