文化大革命以采,我县广大山区建起了大量小水电站,白天推磨、碾米、打糠,晚上发电照明。群众反映这种小电站自己建得起,管得了。这些小电站大都是用水泵装起来的。因为山区水源小,一般在0.1秒立米以下,而0.05秒立米以下的占大多数;落差比较容易取得,修几十米到几百米长的引水渠,就能取得15～40米左右的水头。适合这样条件的小型水轮机无货供应,使用地方自产的小水轮机(如双击式小水轮机),从易损程度、效率和价格等方面比较,都不如使用水泵。第二个原因是:部分抽水站在雨季及以后几个月内(一般在七月至下一年一月),没有提灌任务,可用来发电或带动其他加工机具,作到一机多用。用水泵(离心泵、混流泵、轴流泵)代替水轮机,
The Cultural Revolution to mining, the vast mountainous areas in our county built a large number of small hydropower stations, grinding during the day, rice, chaff, power generation lighting at night. The masses reflect that this small power station can be built up and managed well. Most of these small power plants are fitted with water pumps. Because of mountain water, generally less than 0.1 seconds cubic meters, while less than 0.05 seconds cubic meters accounted for most of the gap is relatively easy to obtain, repair a few tens of meters to hundreds of meters long diversion canal, you can get about 15 to 40 meters head . Small turbines suitable for such conditions are not available from stock, and the use of local self-produced small turbines, such as double-shot turbines, is not as good as using pumps in terms of vulnerability, efficiency and price. The second reason is that some pumping stations have no lifting tasks during the rainy season and in the months to come (generally from July to January of the next year) and can be used to generate electricity or drive other processing machines for use in a single machine. Water pump (centrifugal pump, mixed flow pump, axial flow pump) instead of turbine,
