水泵的性能参数,是水泵运行管理的重要依据,它越全面就越有利于各项性能的发挥和利用,其使用效率就越高,也就越经济越安全。然而目前水泵厂家一般只向用户提供泵段在正常运行情况下,接近设计扬程的性能参数,因而给用户在水泵的运行管理当中、泵站的规划设计当中带来了很多局限 Pump performance parameters, is an important basis for the operation and management of the pump, the more it is more conducive to the performance and utilization of various properties, the higher the efficiency of its use, the more economical the more secure. However, at present, the pump manufacturers generally only provide users with performance parameters that are close to the design lift in normal operation of the pump section. Therefore, to the user in the operation and management of the pump, the planning and design of the pumping station bring a lot of limitations
