Design and manufacture of 22MPa H₂ filling diaphragm compressor

The rapid development of the hydrogen energy industry has made the transportation of hydrogen by 22MPa tube-bundle vehicles an important scenario in "hydrogen production, storage, transportation, and refueling". The GD5 type H₂ filling diaphragm compressor that our company has developed and maturely applied is the mainstream in this market. Due to its efficient compression efficiency, good operational stability, low failure frequency, and reasonable layout structure, it occupies 70% of the H₂ filling market share. Our company entered and actively laid out the H₂ filling market very early. Benefiting from the company's mature design experience in G4/G5 large compressors, for the GD5 type H₂ filling diaphragm compressor, through in-depth research on the characteristics of the H₂ medium and in-depth theoretical research and experimental data feedback on the compressor's operation when compressing this medium, including noise, vibration, cylinder head membrane cavity curve and diaphragm life, gas valve characteristics, oil circuit system characteristics, servo valve characteristics, etc., a reasonable design, production and operation plan for the H₂ filling diaphragm compressor is obtained. And continuously obtain a large amount of operation conditions and after-sales problem feedback from the actual application of customers, and summarize experience to guide design and production, thereby further improving the rationality of the H₂ filling diaphragm compressor product and becoming one of our company's core products in the hydrogen energy industry.
