Diaphragm Compressor

Diaphragm compressors are used to compress gases for industrial applications and fuel cells. They have a compact design and require minimal maintenance. They are also energy-efficient and have a long service life. However, they are susceptible to leaks and can be difficult to operate if the seal is damaged or worn out.

In order to solve the problems, a 90 MPa diaphragm compressor performance test rig was designed to evaluate the beneficial effect of managing oil temperature on enhancing its performance. The structural parameters of the diaphragm compressor were determined, and a simulation model was built to study its thermodynamic processes. The results indicate that limiting the gas discharge temperature and improving its volumetric efficiency can be achieved by enhancing the heat exchange between the hydraulic oil and compressed gas.

Diaphragm Compressor: A Comprehensive Guide

During the compression process, the piston in the hydraulic cylinder moves back and forth, pushing the diaphragms to deform them. As a result, the gas in the gas cavity is compressed and pushed out of the cylinder through the vent. This process is repeated over and over, resulting in the production of compressed gas that can be used for various processes.

A diaphragm compressor has good cylinder heat dissipation and is close to isothermal compression, which makes it the ideal choice for compressing toxic and rare gases. It is used in the food and pharmaceutical industry, petrochemical industry, nuclear power generation, aerospace industry, military equipment and scientific research experiments.
