多沙水流上建抽水站,在国内始于五十年代后期,六十、七十年代增多,到目前为止,据不完全统计,已建成中、大型的抽水站约200余座。运行时间,一般为十余年,最长达二十余年,从一些站的运行实践来看,由于泥沙问题,造成水泵磨损、效率降低、出水量减小,改变了水泵工况。本文根据一些站的运行经验教训,就多沙水流水泵的装置工况的几个问题进行分析探讨。
Dusha Water Station built on pumping stations in the country began in the late fifties, sixties and seventies increased, so far, according to incomplete statistics, has completed the construction of large pumping stations about 200 seats. The running time is generally more than ten years and the longest is more than 20 years. According to the operation practice of some stations, due to sediment problem, the pump is worn, the efficiency is reduced, the amount of water discharged is reduced, and the condition of the pump is changed. Based on the operation experience of some stations, this article analyzes and discusses some problems of the operating conditions of the device of multi-stream water pump.
