What is a diaphragm compressor?

Diaphragm compressor is a specially designed positive displacement compressor, which uses the reciprocating deformation of flexible diaphragm (diaphragm) to compress gas, and realizes the complete isolation of compressed gas from lubricating oil and driving parts (such as piston). This unique structure makes it an ideal choice for treating high-purity, high-value, toxic and harmful or highly flammable gases.

Compared with ordinary compressor, diaphragm compressor has the characteristics of high sealing and purity, high safety, stable operation and long life.

Core special requirements include:

1. Extremely high sealability and purity: relatively no leakage, no pollution, and the original purity of gas can be maintained. It is especially suitable for semiconductor industry (such as krypton and xenon), food industry (such as carbon dioxide), pharmaceutical manufacturing and scientific research.

2. High safety: suitable for compressing toxic (such as hydrogen chloride), flammable (such as hydrogen and acetylene), highly corrosive or radioactive gases.

3. High compression efficiency: Because the gap between the diaphragm and the gas head is very small (the clearance volume is almost zero), the volumetric efficiency is very high, especially suitable for the working conditions of high pressure ratio and small flow rate.

4. Extremely high pressure can be reached: through multistage compression, the outlet pressure can reach 300mpa or even higher, which is often used for filling high-pressure gas cylinders (such as breathing air and cng for natural gas vehicles), laboratory and industrial production.

Diaphragm compressor is a precise, safe and efficient solution for high-pressure gas compression. Its tightness and gas purity. It is an irreplaceable key equipment in high-end manufacturing, new energy, cutting-edge technology and other fields that have extreme requirements for gas quality and safety. With the development of emerging industries such as hydrogen energy, the technical importance of diaphragm compressors has become increasingly prominent.
