ZMJ(SH:601717) Zhong Guo Chan Ye Jing Ji Xin Xi Wang·2025-07-17 22:02Core Viewpoint - The successful deployment of China's first fully domestically produced 40 MPa high-pressure large-capacity centrifugal gas injection compressor at the Yaha gas storage facility in the Tarim Oilfield marks a significant milestone in achieving complete equipment localization in the gas storage sector, breaking foreign technology monopolies and enhancing national energy security [1][2]. Group 1: Technological Advancements - The research team developed several key innovative technologies for the domestication of high-pressure centrifugal compressors, including a compact drive scheme using "variable frequency motor + gearbox + coaxial high and low pressure cylinders," which significantly reduces footprint and investment costs [2]. - The innovative impeller manufacturing utilized narrow three-dimensional spark erosion processing technology, successfully creating impellers suitable for high pressure, high efficiency, and low flow conditions [2]. - The team optimized the high-pressure cylinder rotor structure, accurately calculating rotor thrust under high-pressure conditions and addressing sealing challenges with a "honeycomb structure + counter-rotating flow seal" combination technology [2]. Group 2: Economic Impact - The 40 MPa high-pressure centrifugal compressor has entered the installation and debugging phase, resolving key supporting issues for the Yaha gas storage facility, and reducing costs by over 50% compared to imported equipment [2]. - The technology developed has broad application potential in industries such as petroleum, petrochemicals, and metallurgy, indicating significant promotional value [2].
