Description

Novel diaphragm compressor

Technical Field

Background

Diaphragm compressors are reciprocating compressors that compress and deliver gas by reciprocating a diaphragm in a cylinder. The diaphragm is clamped by two limiting plates along the periphery and forms a cylinder, and the diaphragm is driven by mechanical or hydraulic pressure to reciprocate in the cylinder, so that the compression and the conveying of gas are realized. A mechanically driven compressor using a diaphragm made of rubber or plastic is only suitable for applications where the displacement is several cubic meters per hour and the discharge pressure is about 1.2 MPa, and is generally made in a single stage or two stages. The diaphragm compressor is a positive displacement compressor with special structure, and has the features of great compression ratio, high sealing performance and no pollution of compressed gas caused by lubricating oil and other solid impurity. Therefore, the compressor is suitable for compressing gases with high purity, rare, precious, flammable, explosive, toxic, harmful, corrosive, high pressure and the like. The metal diaphragm is adopted and is driven by hydraulic power, the exhaust gas volume can reach 100Nm3/h, the exhaust gas pressure of multi-stage compression can exceed 100 MPa, and the compressor is suitable for conveying and pressurizing various gases and can also be used as a booster compressor behind an oil-free lubrication compressor. The ratio of the cylinder working volume surface area to the cylinder volume of the diaphragm compressor is much larger than that of the reciprocating piston compressor, and the compression of gas is close to an isothermal process, so the pressure ratio of each stage can be as high as 25. Is suitable for various purposes under the condition of small exhaust volume. Such as for small air supplies, pneumatic regulators, aeration in aquarium tanks, and the transportation and pressurization of oil-free, toxic, corrosive, valuable, or radioactive gases in the chemical industry.
