High-pressure diaphragm compressor

A high-pressure diaphragm compressor, wherein the high-pressure diaphragm compressor comprises a gas-side diaphragm head and an oil-side diaphragm head which are sequentially disposed in an axial direction;

• a diaphragm and an oil distribution disc are disposed between the gas-side diaphragm head and the oil-side diaphragm head, the diaphragm and the oil distribution disc are clamped between the gas-side diaphragm head and the oil-side diaphragm head, and a gas-side diaphragm cavity and an oil-side diaphragm cavity are respectively formed between the diaphragm and the gas-side diaphragm head as well as between the diaphragm and the oil distribution disc;
• an oil cylinder hole is provided in the oil-side diaphragm head, a piston is disposed in the oil cylinder hole, and a piston rod is disposed below the piston;
• and an upper end of the piston rod abuts onto a lower end of the piston, the piston may be separated from the piston rod, and a lower end of the piston rod is connected with a compressor crank-connecting rod mechanism.
