电力排灌泵站和水电站在常德市的总装机有近40万千瓦,对于其进水侧的污物清除方法,一般都采用人工打捞,这不仅耗用的劳力多,需要的劳动强度大,且难以彻底清除,阻水现象十分严重,使拦污栅前后出现较大的水位差,造成进水池水流流态紊乱,使水泵受到汽蚀破坏,长期影响机组正常运行和效益的发挥,同时,因污物堵塞,使拦
The total installed capacity of electric drainage irrigation pumping station and hydropower station in Changde City is nearly 400,000 kilowatts. For the method of removing pollutants on the influent side, artificial salvage is generally adopted, which not only consumes more labor but also requires more labor intensity, and It is difficult to completely remove the water blocking phenomenon is very serious, so that before and after the trash rack a larger water level difference, resulting in inflow pool water flow disorders, the pump cavitation damage, long-term impact on the normal operation of the unit and the effectiveness of play, at the same time, due to Dirt blockage, so block
