1.As a high-end model of positive displacement compressors, GD diaphragm compressors, with their unique diaphragm sealing structure and precise engineering design, achieve clean compression and safe transportation of high-purity and high-pressure gases. They are the core equipment for meeting the requirements of difficult gas treatment.
The GD diaphragm compressor completely isolates the gas chamber from the hydraulic chamber through a metal diaphragm, fundamentally eliminating the contact between lubricating oil and compression medium. It is perfectly suitable for processing high-purity, rare and valuable, flammable and explosive, toxic and harmful, and corrosive gases, and widely serves key industries such as new energy, chemical, nuclear power, medical, and electronics, providing reliable power support for industrial upgrading and green development.
Core advantage: Precise adaptation to harsh working conditions
1. Ultimate cleanliness: ensuring gas purity and zero pollution
The GD diaphragm compressor adopts fully sealed diaphragm isolation technology, and the compressed medium does not come into contact with any lubricants throughout the process, avoiding secondary
pollution from the source and achieving a stable gas purity output of over 99.9999%. Whether it is high-purity gases such as hydrogen and helium, or corrosive gases such as chlorine and hydrogen sulfide, they can maintain their original medium characteristics and fully meet the strict requirements for gas cleanliness in industries such as electronic semiconductors, high-end medical care, and specialty chemicals.
2. High voltage and high efficiency: Wide range parameters cover diverse needs
The GD diaphragm compressor relies on optimized membrane chamber curve design and imported high-precision gas valve components to significantly improve volumetric efficiency and compression stability. The product displacement covers 30-2000 Nm ³/h, with a maximum exhaust pressure of up to 100MPa. It can achieve single-stage or multi-stage compression and accurately match different working conditions from low-pressure gas pressurization to high-pressure gas cylinder filling, pipeline transportation, etc. Taking the typical model GD5-750/9.5-220 as an example, the GD diaphragm compressor can stably compress hydrogen gas to 22MPa at an intake pressure of 0.95MPa, with a single displacement of 750Nm ³/h, efficiently meeting the upstream filling requirements of hydrogen refueling stations.
3. Safe and reliable: ensuring stable operation throughout the entire chain
The cylinder body of the GD diaphragm compressor adopts a non oil distribution plate structure design, reducing the number of sealing surfaces and minimizing the risk of leakage; Equipped with comprehensive safety monitoring devices such as medium leakage alarm and low oil pressure alarm, it can capture operational abnormalities in real time and trigger warnings. The whole machine adopts a D-type structural layout, which runs smoothly with low vibration and noise levels better than industry standards; Core vulnerable parts such as membranes are treated with special heat treatment processes and designed for low-speed operation, significantly extending their service life. The overall service life of the equipment can reach more than 20 years, greatly reducing operation and maintenance costs.
4. Convenient operation and maintenance: integrated design enhances adaptability
The GD diaphragm compressor is integrated into the pry mounted chassis, with a compact and reasonable structure that is easy to transport, lift, and install on site; The humanized instrument interface, simple layout of oil, water, and gas pipelines, and the design of the middle body window make the operation status visualized and the operation and maintenance more convenient. The lubrication system adopts a built-in oil supply and pressure regulation design, providing stable and clean lubricating oil, and the oil system has no leakage, further improving the convenience of equipment operation and maintenance and environmental adaptability.
