轴流泵是我国目前使用最为广泛的泵型,一般以60～90度弯管出水,虹吸式拍门断流,中小型立式轴流泵机组装机效率仅为30%～50%。该泵弥补了上述缺陷,其技术特点如下:采取开敞式布置,提高了水泵的装置效率,为安装和检修提供了方便;采用先进的泵轮和导叶,提高了水泵的运行性能;采用帘门断流,减少出口损失,减轻断流时的振动;采用 Axial flow pump is currently the most widely used pump in our country, generally 60 ~ 90 degrees elbow pipe, siphon flap door cut off, small and medium-sized vertical axial flow pump assembly efficiency of only 30% to 50%. The pump to make up for these shortcomings, and its technical features are as follows: take an open layout to improve the efficiency of the pump device for installation and maintenance provides a convenient; the use of advanced pump wheel and guide vane, to improve the pump performance; the use of Shut off the curtain to reduce the export loss, reduce the vibration when the flow; adopted
