针对郭滩水源工程清水厂清水泵输入量偏大，缺乏在低水量工况经济、合理、安全的调节供水方式，造成在单供联合站时，供水不经济、生产不安全的问题，结合生产实际，提出应用叶轮切削技术改造清水泵技术方案。实施后，解决了单供联合站时的弊压问题，实现了安全生产，取得了明显的经济效益。 In view of the water input of Qingshui plant of Guotan water source project is too large, lack of economical, reasonable and safe water supply regulation in low-water conditions, resulting in the problem of uneconomical water supply and unsafe production when combined with single-supply station, In fact, the application of impeller cutting technology to improve water pump technology program. After the implementation, the problems of the disadvantages of single-supply combined station were solved, safety production was realized and obvious economic benefits were obtained.
