Our diaphragm type compressors are engineered to deliver exceptional performance, efficiency, and durability across a wide range of industrial applications. These compressors use a flexible diaphragm to compress air or gases, offering a unique solution for applications that require precise control, high purity, and safe operation.

Working principle

A reciprocating compressor that compresses and delivers gas by reciprocating the diaphragm in a cylinder. The diaphragm is clamped by two restriction plates along the periphery and forms a cylinder. The diaphragm is driven by mechanical or hydraulic means to reciprocate inside the cylinder, thereby achieving compression and transportation of gas. Compressors that use metal diaphragms and are driven by hydraulic forces are quite common, with a displacement of thousands of standard cubic meters per hour. The size of the displacement is generally determined by the compression ratio between the inlet and outlet pressures. Currently, our company sells compressors with a displacement pressure exceeding 87 megapascals, which are suitable for transporting and pressurizing various gases, and can also be used as booster compressors after oil-free lubrication compressors. The thickness of the metal diaphragm is generally around 0.5 millimeters. The lifespan of the diaphragm depends on the selected material and its surface roughness. Due to the large motion mass of hydraulic drive, the average speed of the piston in the hydraulic part can only be taken as 2 meters per second, so the speed of the machine is usually in the range of 300-500 revolutions per minute. The ratio of the cylinder working volume surface area to the cylinder volume of a diaphragm compressor is much larger than that of a 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. Diaphragm compressors are suitable for various applications with small displacement due to their good cylinder sealing and non polluting compressed gas. Used as a small gas supply device, pneumatic regulator, ventilation device for aquarium feeding pools, as well as for the transportation and pressurization of oil-free, toxic, corrosive, valuable, or radioactive gases in the chemical industry.
