Diaphragm compressor is a high purity gas compression deviceDiaphragm compressor is a high purity gas compression device that achieves gas compression through a flexible diaphragm reciprocating motion within the cylinder. Diaphragm compressor is mainly composed of motor, base, crankcase, crankshaft connecting rod movement mechanism, cylinder block components, oil and gas pipelines, electric control system and some accessories. The principle of gas-assisted oil-free high-pressure nitrogen compressor is that nitrogen and hydraulic oil are completely isolated, and the compression process does not produce any pollution, completely avoiding the defects of high nitrogen oil content of the finished product of oil-lubricated piston high-pressure compressor, regularly sliding the filter element and adding special compressor oil. Simple structure, easy maintenance, high reliability, stable pressure output, minimal running sound.
