浙江省平原水网地带使用抽水机较多,由于河流密布,田块较小,实际扬程一般只在3米左右,抽水机动力大部分是8马力和12马力的。1954年以前一直沿用过去的旧水泵,扬程高、流量小、效率低。1955年为了提高效率,根据各地的实际扬程,改用由杭州铁工厂和台州水泵厂制造了扬程4.5米和5米的水泵,出水量大大增加,每马力的受益田亩逐年扩大,1958年浙江水泵厂又制成混流泵,同时各地又制成各种口径的木管轴流泵,不但流量增加很多,而且节约了大量钢材。由于水泵与动力机配套比较合理,加以改进了用水管理,节约用水。现在全省平均每马力灌田提
Zhejiang Province, the plain water network using more water pumps, due to the river is covered, the plots smaller, the actual lift is generally only about 3 meters, most of the pump power is 8 horsepower and 12 horsepower. Before 1954, it used the old pumps of the past and had high lift, low flow rate and low efficiency. In 1955 in order to improve efficiency, according to the actual lift around, switch to the iron factory in Hangzhou and Taizhou Pump Factory 4.5 meters and 5 meters of the pump, a substantial increase in water output per horsepower to benefit Tian acres have expanded each year in 1958, Zhejiang Pump The factory is made of mixed-flow pump, at the same time around the tube made of various caliber axial flow pump, not only increase the flow of a lot, but also save a lot of steel. As the pump and power plant more reasonable package, to improve the water management, water conservation. Now the province’s average horsepower Tian Tian filed
