Core Viewpoint - The domestically developed VM160 pumped storage power station air compressor has achieved international leading technology standards, marking a significant advancement in China's energy technology sector and breaking foreign monopolies in this equipment field [1][2]. Group 1: Technological Advancements - The VM160 air compressor is the first domestically produced unit for pumped storage power stations, successfully implemented in the second phase of the Meizhou pumped storage power station in Guangdong [1]. - The development process included selecting a technical route, structural performance design, equipment manufacturing, and product engineering applications, focusing on optimizing the equipment's overall performance [2]. - The chosen "medium pressure oil-free" technology eliminates the need for lubricating oil in the air compression process, simplifying operations and reducing environmental pollution [2]. Group 2: Performance and Efficiency - The VM160 air compressor achieves a gas pressure of 8.5 MPa and a compression speed of 11.5 cubic meters per minute, with a strength equivalent to supporting the weight of 425 cars on a one-square-meter area [3]. - The innovative coaxial direct drive architecture enhances transmission efficiency to 100% and significantly lowers maintenance costs compared to traditional belt-driven systems [2]. - Key performance indicators of the domestically produced air compressor show improvements over imported models, with noise levels, cylinder body vibration, and motor vibration reduced by approximately 14%, 32%, and 72% respectively [3]. Group 3: Economic Impact and Market Potential - The implementation of the VM160 air compressor in pumped storage stations is projected to generate economic benefits of up to 81 million yuan over a 30-year usage period [3]. - By 2030, China's pumped storage capacity is expected to exceed 120 million kilowatts, nearly doubling the current scale, indicating a robust growth trajectory for the industry [3]. - The full domestic production process of the air compressor is anticipated to yield significant economic and environmental benefits, with promising market application prospects [3].
