Core Viewpoint - The successful completion of the spring irrigation task for the Xi'an water supply project in the arid central region marks a significant advancement in the domestic production of large-capacity water pumps, achieving core equipment localization and meeting international performance standards [1][2]. Group 1: Project Overview - The Xi'an water supply project has supplied a total of 1.192 million cubic meters of water, utilizing domestically produced dual-import multistage water pumps [1]. - The project involved collaboration among various entities, including the Ningxia government, Chongqing pump manufacturers, and Tsinghua University, focusing on key technologies such as efficient hydraulic modeling and wear resistance [1]. Group 2: Technological Achievements - The newly developed water pumps have an efficiency of 85%, comparable to leading global products, and outperform in vibration, noise control, and bearing temperature rise [2]. - The optimized flow path and wear-resistant technology have increased the lifespan of the pumps by over 30% [2]. Group 3: Economic Impact - The project has demonstrated that domestic water pumps can match the performance of joint venture products while reducing procurement and maintenance costs by 30% [2]. - The core sealing components of the pumps can save approximately 40,000 yuan per set, contributing to overall cost efficiency [2]. Group 4: Broader Implications - The localization of key water pump equipment reduces reliance on imports, enhancing supply chain security and ensuring the self-sufficiency of essential civil engineering projects [2]. - The project also achieved domestic production of core chips and algorithms for millimeter-wave radar water level and flow meters, strengthening safety measures for water monitoring and disaster prevention [2].
