What is the function of the hydraulic differential controller in the compressor?
When the oil pressure drops to insufficient to make the compressor work safely, it has not been restored to the set oil pressure value during the delay setting
When the compressor works, an oil pump forces the oil circulation lubrication and cooling, and the oil pressure difference controller is a safety switch for the screw compressor
The main circuit is cut off and the compressor stops working so as to protect the compressor from damage.
