泵站扬程的确定,特别是设计扬程的确定,是泵站规划设计中的重要问题,它直接关系到水泵造型的合理性,装机容量的大小,从而影响到工程投资,运行管理费用,以及是否满足抗旱排涝的要求等等。如泵站扬程设计不当,将导致水泵造型不合理,增加工程投资。而且使水泵长期在低效率、高能耗的工况下运行,造成能源的浪费。同时,还容易产生汽蚀和震动,缩短机组使用寿
The determination of pumping station lift, especially the design lift, is an important issue in the planning and design of pump station. It is directly related to the rationality of pump modeling and the size of installed capacity, which affects the project investment, operation and management costs, and whether Meet the requirements of drought and drainage and so on. If the pumping station head design is improper, will lead to irrational pump shape, increase project investment. But also make the pump long-term operation in low efficiency, high energy consumption conditions, resulting in energy waste. At the same time, but also easy to produce cavitation and vibration, shorten the unit life
