In what applications are diaphragm compressors and piston compressors used respectively?

Diaphragm compressors are used in applications with a gas discharge volume of several cubic meters per hour and a discharge pressure of around 1.2 MPa; they are often used for handling toxic and harmful gases, and are typically designed as single-stage or two-stage units. I’m not sure about piston compressors; I’d like some advice.

Pistons are generally used in high-pressure and ultra-high-pressure applications. Diaphragms are typically used in applications where leaks are not allowed.

A diaphragm compressor is a reciprocating compressor that compresses and transports gases by means of the reciprocating motion of a diaphragm within a cylinder. The diaphragm is clamped along its perimeter by two retaining plates to form a cylinder; it is driven hydraulically to move back and forth within this cylinder, thereby enabling the compression and delivery of gas. It features a high compression ratio, a wide pressure range, and good sealing performance. Since its air chambers require no lubrication, this ensures the purity of the compressed gas; it is particularly suitable for the compression, transportation, and bottling of flammable, explosive, toxic, harmful, and high-purity gases. Such as oxygen, argon, nitrogen, acetylene, sulfur hexafluoride, carbon dioxide, etc. Depending on the exhaust pressure, it is generally designed as single-stage or two-stage. Pressure range: 0.5–40 Mpa; Flow rate: 5–1000 Nm3/h. Jiangsu China Railway diaphragm compressors, a military-grade brand. 13151236781 QQ 1042911086

There are existing performance records for carbon monoxide use, mostly in the non-ferrous metals industry, such as Gen Nickel and Jinchuan Group; you might want to ask Beijing Huayinglian Compressors
