diaphragm compressor for hydrogenation station gases

Diaphragm compressors are renowned for their ability to compress gases without direct contact between the compressed medium and any lubricant or mechanical parts. This ensures both exceptional gas purity and reliable sealing performance, making diaphragm compressors ideal for applications demanding high-purity gases—such as hydrogen, helium, nitrogen, and more. They are also suitable for handling hazardous gases, including corrosive, flammable, toxic, and radioactive types.

Diaphragm Compressor Features

1. High gas purity: The isolation between gas and compression components ensures gas purity up to 99.999%, perfect for applications requiring ultra-high purity.
2. Lubrication-free operation: No lubricating oil is needed for compression, so sensitive gases are never contaminated—maintaining gas quality across all applications.
3. Strong sealing: Special diaphragm and sealing design prevents gas leakage, ensuring safety and stability during compression.
4. Large compression ratio: Supports multi-stage compression from low to high pressure, meeting diverse pressure requirements.
5. Wide gas applicability: Suitable for compressing hydrogen, helium, nitrogen, oxygen, hydrogen sulfide, nitrogen trifluoride, and many more gases.
6. Safe and reliable: Handles toxic, corrosive, or explosive gases with high safety, ideal for chemical, petroleum, and nuclear power industries.

The Working Principle of Diaphragm Compressor

1. Diaphragm drive: Hydraulic or mechanical systems move the diaphragm back and forth; cyclic expansion and contraction compresses the gas in the chamber.
2. Gas intake and compression: Outward diaphragm movement draws gas through the suction valve; inward movement compresses and discharges gas via the exhaust valve.
3. Multi-stage compression: Multi-stage technology increases gas pressure efficiently and stably, ensuring optimal performance for high-pressure applications.
4. Non-polluting design: The diaphragm isolates gas from mechanical parts, eliminating risk of lubricant or cylinder wall contamination.
5. Cooling system: Integrated cooling dissipates heat generated during compression, maintaining stable operation and extending equipment life.

Diaphragm Compressor Applicable Working Conditions

• Rare gas filling: Reliable, high-purity compression and filling of rare gases (helium, neon, xenon) for scientific, medical, and industrial uses.
• Scientific research installations: Supplies stable, ultra-pure gases for analytical equipment (mass spectrometers, gas chromatographs, etc.).
• Process small pilot plant: Accurate, stable gas supply for new materials and process development, supporting small-scale, high-purity experiments.
• Small flow rate gas compression: Maintains high purity and pressure for low-flow specialty gases, ideal for precision manufacturing or specialty filling.
