孟加拉国农业大学研制了五种不同规格的低扬程灌溉手动转轮泵,其规格分别为8.9、9.3、10.8、12.0、13.0cm,这些泵在5.48m 以内的不同吸程下进行了试验,当吸程在1.29～5.48m 范围时,最小和最大规格泵的流量范围分别为21.1～7.47和44～137.4L/min。该类泵所需功率在一个正常人所能发出的功率范围内。泵的结构简单,价格便宜,而且可就近制造。适合小地块和零散地块使用。 Bangladesh Agricultural University has developed five different specifications of low-lift irrigation hand wheel pump, the specifications were 8.9,9.3,10.8,12.0,13.0 cm, these pumps within 5.48m different suction under the test, when The suction flow range of 1.29 ~ 5.48m, the minimum and maximum size of the pump flow range were 21.1 ~ 7.47 and 44 ~ 137.4L / min. The power required for this type of pump is within the power range of a normal person. Pump structure is simple, cheap, and can be manufactured nearby. Suitable for small plots and scattered plots.
