- product introduction:DPC series differential pressure controllers also called oil pressure controller(hereinafter referred to as controller). It is used in protecting the refrigeration compressor and other mechanical engineering means protection for pressure lubrication.In refrigeration system,In order to make all moving friction parts of compressor can get good lubrication,lubrication system must be kept in a certain 0il pressure.If oil pressure too low, compressors will happen“Cylinder sticking" for losing oil in normal running or starting; even burn up bearing bush of the compressor. In order to prevent this phenomenon,must install the safety device of control oil pressure. The controller has this function. It receives two signals of discharge pressure from lubricating oil pump and suction pressure from compressor. And also maintains a certain differential range between the two pressure,when the differential value is less than the set value,make the compressor turn off,play the role of safety protection function. DPC series differential pressure controllers’ micro switch structure ensure reliable quick conversion function. DPC series differential pressure controllers have earned CE, GIC.
