我国机电排灌动力保有量已达7000万kW,固定泵站达到50多万座,水泵达600万台以上。但是在泵站建没和管理中,由于泵站本身及泵站工作条件的原因,造成水泵普遍汽蚀、磨蚀严重,使水泵,特别是叶片和叶轮室使用寿命大大缩短,造成了严重的浪费,有时甚至影响泵站的正常运行。
China’s electromechanical irrigation and drainage power holdings have reached 70 million kW, fixed pumping station to reach more than 50 million, water pump up to 6 million units. However, in the construction and management of pump stations, pump cavities are generally cavitated and seriously eroded due to the pump station itself and the working conditions of pump stations, which shortens the service life of pumps, especially the blades and impeller rooms, resulting in serious waste , And sometimes even affect the normal operation of pumping stations.
