农村小水电站厂房集水井的排水设备,大都采用电动离心式水泵抽水。由于离心式水泵有需用动力电源、机械故障较多和维修困难等缺点,因此,采用一套新型的排水设备,也是一个值得研究的问题。嵩县铺沟水电站集水井的排水设备,采用了抽水射流泵装置。该泵以压力前池的压力水为动力,利用射流抽气原理抽水的。铺沟水电站为渠道引水式水电站,引水流量为12米~3/秒,发电水头为16米,装机容量为两台806千瓦水轮发电机组。水电站自1983年5月建成发电以来,抽水射流泵发挥 Small hydropower plant in rural drainage wells set water wells, mostly by electric centrifugal pump pumping. Due to the disadvantages of centrifugal pumps, such as the need of power supply, mechanical breakdown and maintenance difficulties, adopting a new type of drainage equipment is also worth studying. Song County ditch ditch water collection wells drainage equipment, using a pumping jet pump device. The pressure of the pump before the pressure water pool as the driving force, the use of jet pumping principle pumping. The Shuigou Hydropower Station is a water diversion type hydropower station with a water diversion flow of 12m ~ 3 / s and a generating head of 16m. The installed capacity is two 806kw hydro-generating units. Since the hydropower station was built in May 1983, the pumping jet pump has been used
