Advantages of Helium Diaphragm Compressor
01
100% Oil-Free and Ultimate Purity Retention
The diaphragm compressor uses a metal diaphragm to completely physically isolate the hydraulic oil from the compressed gas, achieving absolutely no lubrication in the cylinder. This characteristic ensures that the helium is not contaminated by any oil during compression, maintaining an ultra-high purity of over 99.999%, fully meeting the stringent cleanliness requirements of the semiconductor, scientific research, and medical fields.
02
Static Seal Zero Leakage and High-Pressure Capability
The gas is sealed within the chamber formed by the diaphragm and cylinder head, which is a static sealing structure that fundamentally prevents gas leakage. This is crucial for preventing the loss of expensive helium. Simultaneously, this compressor type offers a high single-stage compression ratio, enabling it to achieve discharge pressures up to 50 MPa or even higher with fewer stages, making it highly suitable for high-pressure helium filling and transportation.
Key Design Points for Helium Diaphragm Compressor
01
Strictly Control the Single-Stage Compression Ratio and Enhance Cooling
Given helium's high adiabatic index and significant temperature rise during compression, the design must strictly control the single-stage compression ratio to prevent excessively high discharge temperatures that could affect equipment stability and diaphragm life. An efficient inter-stage cooling and final cooling system (water-cooled or forced air-cooled) must be provided to make the compression process as close to isothermal as possible, effectively controlling the temperature rise.
02
Use Compatible Materials and High-Cleanliness Treatment
All flow-wetted components in contact with helium should be made of compatible materials such as high-quality stainless steel (e.g., 304, 316L). During manufacturing and assembly, these components must undergo strict degreasing, cleaning, and drying processes to eliminate any potential sources of contamination and ensure the initial purity of the gas.
03
Configure Multiple Safety and Purity Monitoring Systems
A diaphragm rupture monitoring and alarm device must be installed to immediately alarm upon diaphragm failure, preventing oil-gas mixing. The system should be equipped with safety valves at each stage for overpressure protection.

Frequently Asked Questions
Why is a diaphragm compressor ideal for handling helium gas?
Helium is a highly valuable and small-molecule gas. Diaphragm compressors feature a static sealing structure that completely prevents gas leakage. They also utilize a metal diaphragm to isolate process gas from the hydraulic oil, ensuring 100% oil-free compression and maintaining helium purity above 99.999%.
How does the compressor manage helium's high temperature rise during compression?
Helium has a high adiabatic index, causing significant heat generation during compression. To counter this, the design strictly limits the single-stage compression ratio and integrates highly efficient inter-stage and final cooling systems (either water-cooled or forced air-cooled) to maintain safe operating temperatures.
What materials are used for components in contact with helium?
All flow-wetted components are manufactured using high-quality, helium-compatible materials such as 304 or 316L stainless steel. These components undergo strict degreasing, cleaning, and drying processes to eliminate any contaminants before assembly.
What safety features protect against diaphragm failure?
The compressor is equipped with a diaphragm rupture monitoring and alarm device. If a diaphragm fails, the sensor immediately triggers an alarm and shuts down the system to prevent any mixing of hydraulic oil and helium gas. Overpressure protection is also provided via stage-by-stage safety valves.
What maximum discharge pressures can these helium compressors achieve?
Depending on the selected model (such as the GL or GD series), these compressors can achieve discharge pressures of 50 MPa, 100 MPa, or even higher, making them highly suitable for high-pressure storage, cylinder filling, and pipeline transportation.
