diaphragm compressor for process pilot gas compression

Diaphragm compressors are specially designed volumetric compressors, where the movement of the diaphragm isolates the compressed gas from the outside environment and ensures that the gas does not come into contact with any contaminants during the compression process.

Description

Diaphragm compressors deliver exceptional sealing performance and maintain the highest purity of compressed gas by ensuring zero contact with lubricants. They are widely used for compressing hydrogen, helium, nitrogen, and other critical gases—including flammable, explosive, corrosive, and radioactive types—across diverse industrial applications demanding gas purity and safety.

Features of Diaphragm Compressor

  1. Pollution-free compression: Gas never contacts oil or lubricant, achieving up to 99.999% purity—ideal for high-purity gas processing.
  2. High sealing performance: Precision diaphragm design ensures complete sealing and prevents leakage, boosting both efficiency and safety.
  3. Large compression ratio and multi-stage capability: Supports large compression ratios and up to three-stage configurations (H, D, L, V, Z types) for a variety of pressure requirements.
  4. Wide applicability: Suitable for compressing hydrogen, nitrogen, oxygen, helium, xenon, hydrogen chloride, hydrogen fluoride, and more; model selection can be tailored to specific gases.
  5. High safety: Excellent for toxic, corrosive, flammable, or explosive gases—sealing and non-leakage design minimizes operational hazards.

Working Principle of Diaphragm Compressor

Utilizing volumetric compression, a flexible diaphragm is driven mechanically to compress gas without lubricant contact:

  1. Gas intake: Diaphragm moves downward, increasing chamber volume and drawing in external gas.
  2. Compression: Diaphragm moves upward, reducing chamber volume and compressing gas, which is then discharged through the outlet.
  3. Sealing guarantee: The diaphragm alone seals the chamber, preventing both contamination and leakage for guaranteed purity.

Applicable Working Conditions

  • Rare gas filling: Efficient, high-purity compression and filling of expensive and irreplaceable gases like helium and neon.
  • Hydrogen refueling stations: Key role in hydrogen compression and storage, ensuring purity and stability for the hydrogen industry.
  • Polysilicon manufacturing: Delivers high purity gas compression for semiconductor and solar industry processes.
  • Fluorine chemical industry: Safe, high-purity compression of corrosive gases such as hydrogen fluoride and nitrogen trifluoride.

Application Areas

  1. Hydrogen energy industry: Essential for clean, high-purity hydrogen compression and storage for energy and mobility applications.
  2. Semiconductor manufacturing: Supplies non-polluting, ultra-pure gases like nitrogen and argon, vital for chip fabrication.
  3. Pharmaceutical industry: Compresses and transports medical gases (oxygen, nitrous oxide), supporting hospital and medical safety standards.
  4. Petrochemical & metallurgical industries: Handles hydrogen chloride, hydrogen sulfide, and more for process gas transport and storage.
  5. Aerospace & nuclear energy: Compresses special gases (helium, xenon) for critical aerospace and nuclear processes.
  6. Scientific research: Provides high-purity gases for analytical tests (mass spectrometry, chromatography) and research experiments.
