Core Viewpoint - The successful development and deployment of China's first fully domestically produced 40 MPa high-pressure large-capacity centrifugal gas injection compressor marks a significant achievement in the gas storage industry, breaking foreign technology monopolies and reducing costs by over 50% compared to imported equipment [1][2]. Group 1: Technological Advancements - The compressor features a compact drive scheme using "variable frequency motor + gearbox + coaxial high and low pressure cylinders," which significantly reduces footprint and investment costs [2]. - Innovations include the use of narrow three-dimensional spark erosion processing technology for the impeller, suitable for high pressure, high efficiency, and low flow conditions [2]. - The development of rotor structure optimization and dynamic analysis methods allows for precise calculations of rotor thrust under high-pressure conditions, addressing sealing deformation and gas excitation issues through a "honeycomb structure + counter-rotating flow seal" combination [2]. Group 2: Performance and Capacity - The newly developed high-pressure centrifugal compressor has a daily processing capacity of 5.5 million cubic meters, with an injection pressure of 40 MPa and a motor power of 23 MW, significantly enhancing the gas storage efficiency [1]. - The compressor is currently in the installation and debugging phase, with plans for official operation in October [2].
