浙江省农村普遍用作灌溉排涝的水泵,是一种单级端吸封闭叶轮的离心式水泵。进出口径为300公厘,用12匹柴油机(或煤气机)间接带动,转速每分钟500转,抽水量为126公升/秒,扬程为4.57公尺,最高效率可达85～88％。转动马力用20匹、600转/分钟时,抽水量为167公升/秒,扬程为5.7公尺。江南的河道纵横,水位又高,这种水泵很适用。几年来各地大量生产,一而又不断的改进设计。在保证质量和强度不降低的原则下,节省原材料,缩短工时,降低成本。设计人员解放思想,破除迷信,结合工人
Zhejiang Province, generally used as irrigation and drainage pumps in rural areas, is a single-stage closed suction impeller centrifugal pump. Import and export diameter of 300 mm, with 12 diesel engine (or gas) indirectly driven speed of 500 revolutions per minute, pumping capacity of 126 liters / second, lift of 4.57 meters, the maximum efficiency of 85 to 88%. Turn the horsepower with 20, 600 rev / min, the pumping capacity of 167 liters / second, head of 5.7 meters. Vertical and horizontal rivers in the South, the water level is high, this pump is suitable. Over the past few years mass production around, one continuous improvement of design. Under the principle of ensuring quality and strength are not reduced, raw materials are saved, working hours are shortened and costs are reduced. Designers emancipate their minds, get rid of superstition, with workers
