[0049] The high-pressure diaphragm compressor oil pressure accompanying control system includes a diaphragm compressor 15 , a pressure transmitter 19 , a proportional overflow valve 18 , and a diaphragm compressor oil pressure accompanying control device 16 . The pressure transmitter 19 measures the discharge pressure value of the diaphragm compressor 15 and converts it into an electrical signal and transmits it to the control terminal of the proportional relief valve 18. The proportional relief valve 18 controls the displacement of its own proportional electromagnet according to the signal of the discharge pressure. Adjust its own overflow pressure to control the outlet pressure of the gear pump 17, so that the oil pressure at the outlet of the gear pump 17 and the exhaust pressure can follow up. The oil pressure at the outlet of the gear pump 17 is generally low, and it is used as low-pressure oil to supply the diaphragm compressor The oil pressure follows the low pressure ch...
