汽蚀是影响水泵使用寿命,普遍存在而突出的问题。为了减轻其危害,在设计时应考虑到海拨造成的影响,尽可能使泵站具有良好水流流态的水工建筑物及管路,但因汽蚀形成原因复杂,破坏情况仍普遍发生.水泵过流部件因汽蚀往往产生凹坑麻点,严重时呈现海绵状和蜂窝状。当汽蚀出现后,水泵水量减少,效率逐步降低。据有关资料介绍,一般下降幅度在
Cavitation is the impact of pump life, widespread and prominent problems. In order to reduce the damage, the design of hydropower station should take into account the impacts caused by the hydropower station. Hydraulic structures and pipelines with good water flow patterns should be taken into account as far as possible. However, the damage is still common due to the complicated cavitation formation. Pump overcurrent components due to cavitation often pits pitting, severe sponge-like and honeycomb. When the cavitation appears, the pump water volume decreases, the efficiency is gradually reduced. According to the information, the general decline in the
