[Haichuan Hydrogen Energy] The group standard for \"Technical Specifications for Diaphragm Hydrogen Compressors\" has completed the approval process at the China Compressed Gas Association
Thread Content
The group standard for \"Technical Specifications for Diaphragm Hydrogen Compressors\" has completed the approval process by the Standardization Management Committee of the China General Machinery Industry Association. The secretariat of the Compressor Branch of the China General Machinery Industry Association plans to hold a meeting on the development of this group standard on June 19, 2023, at Fengdian Jinkaiwei. Fengdian Jinkaiwei will serve as the lead author and work together with major domestic and international diaphragm compressor manufacturers to develop this group standard. Diaphragm hydrogen compressors are one of the key devices in the current hydrogen energy industry chain, and the quality of these devices is directly related to the safe and stable operation of hydrogen refueling stations and hydrogen filling stations. A diaphragm hydrogen compressor is a complex system that includes the compressor unit itself, lubrication oil circuits and refilling systems, cooling systems, drive systems, instrumentation and control systems, as well as piping systems. The safety and stability of these systems are the foundation of the overall quality of diaphragm hydrogen compressors, and they also serve as an important guarantee for the long-term, safe, and stable operation of hydrogen refueling stations. Currently, the manufacturing quality of diaphragm hydrogen compressors used in hydrogen refueling stations and hydrogen filling stations varies across the market. The standards for such compressors focus on different aspects, and they do not fully and accurately cover the technical requirements for diaphragm hydrogen compressors used in these applications; as a result, there are no clear and unified technical specifications or criteria for acceptance. There is an urgent need to develop a technical specification outlining the technical requirements and acceptance criteria for diaphragm hydrogen compressors used in hydrogen refueling stations.
Scope of application and technical content of the group standard: This standard applies to diaphragm hydrogen compressors used in hydrogen refueling stations and hydrogen filling stations, with a rated exhaust pressure not exceeding 100 MPa; other diaphragm hydrogen compressors may refer to this standard for implementation. This standard shall specify the terms, requirements, inspection and testing, inspection rules, marking, packaging, storage, transportation, after-sales service, quality assurance, etc., for diaphragm hydrogen compressors. The group standard \"Technical Specifications for Diaphragm Hydrogen Compressors\" will establish clear requirements, testing methods, and inspection rules for diaphragm hydrogen compressors used in hydrogen refueling stations and hydrogen filling stations. It will serve as a basis for the design, manufacturing, factory inspection, acceptance of such compressors, as well as for compressor users in making their selections.

It seems that there aren’t many compressor models available for low flow rates and multiple pressure ranges. For those of us who work with pilot-scale catalyst testing equipment, this is a real problem – it’s not feasible to have to replace the compressor for each product we use
