1548型泵以新型的水力设计,突破了单级双吸泵水力流道的设计陈规,导致新颖的双吸泵结构型式,具有体积小、重量轻、结构简单、效率高、使用方便等优点(见图1),设计点效率η达83.7％,吸程Hs_允许6.8米(见1548型泵全性能试验曲线(图2)及表1。重量为72.5公斤。占地面积小,泵的出水口可以上下左右转变方向,如果装在一个立式电机上,亦可变为单级双吸立式离心 1548 pump with a new type of hydraulic design, breaking the design of single-stage double suction pump hydraulic runner, resulting in a new double-suction pump structure, with small size, light weight, simple structure, high efficiency, easy to use, etc. See Figure 1), design point efficiency η up to 83.7%, suction Hs_ allows 6.8 meters (see 1548 pump full performance test curve (Figure 2) and Table 1. The weight of 72.5 kg. Small footprint, the pump out The outlet can be up, down, left and right to change direction, if installed in a vertical motor, can also be changed to single-stage double-suction vertical centrifuge
