Diaphragm Gas Compressor
Diaphragm compressors serve a wide range of industries, including hydrogen energy and nuclear power, providing efficient high-pressure gas compression solutions.
As a high-performance positive displacement compressor with a unique design, the diaphragm compressor has become the industry-standard equipment for handling special gases, thanks to its core advantages of zero lubrication, complete sealing, and high purity.
Throughout the compression process, the working medium is completely physically isolated from the lubricant, ensuring gas purity levels of up to 99.999% (or even exceeding 99.9999%). Whether handling high-value rare gases or hazardous media, it offers unparalleled safety and reliability.
Product Features
Key Advantages
Superior Sealing and Contamination-Free Operation: The gas never comes into contact with lubricating oil, eliminating the risk of oil contamination or leakage; purity levels of 99.9999% or higher can be achieved, meeting stringent high-purity gas requirements.
Excellent Heat Dissipation: Effective cooling of the working cylinder facilitates a near-isothermal compression process, allowing for higher compression ratios and stable high-pressure gas output.
Long Service Life and High Reliability: Low operating speeds significantly extend the lifespan of wear parts; diaphragms undergo special heat treatment for greatly enhanced durability; a high-efficiency cooler ensures low-temperature, efficient operation, thereby extending the service life of lubricating oil, O-rings, and valve springs.
Advanced, Energy-Efficient Design: The overall structure is optimized for energy efficiency while meeting process parameters; the diaphragm head utilizes an embedded dual O-ring sealing system, offering far superior sealing performance compared to open-style designs.
Intelligent Safety Features: Equipped with an advanced, reliable diaphragm rupture alarm system; diaphragm installation is non-directional, making replacement quick and easy.
Technical Features
The diaphragm compressor features a newly designed diaphragm cavity profile that effectively enhances volumetric efficiency and optimizes gas valve performance. Low-speed operation minimizes mechanical wear, while a high-efficiency cooling system ensures the unit maintains low operating temperatures and high efficiency during prolonged, high-load operation. The diaphragm head utilizes an embedded dual O-ring sealing structure, significantly improving sealing reliability. A responsive and logically sound diaphragm rupture alarm system further ensures the safety of both the equipment and operating personnel. The overall design meets process requirements while delivering superior energy efficiency and extended maintenance intervals.
