渣浆泵的几种常用结构单级双吸离心泵

如图2-14所示，这种结构泵使用也很广泛，它实际相当于将两个相同的叶轮背靠背地装在一根轴上并联工作，所以这种泵不但流量大，而且可以自动平衡轴向力。单级双吸泵一般采用半螺旋形吸入室，泵体为蜗壳式压水空并水平中开式。轴承装在泵轴的两端，小型泵采用滚动轴承，大型泵采用滑动轴承。这种泵工作平稳可靠，维修方便，只要打开泵盖即可将整个转子取出，可不动进出管路及电机。渣浆泵厂家

Two, several commonly used structure of centrifugal pump single-stage double suction centrifugal pump

As shown in Figure 2-14, this kind of structural pump is also widely used. It is actually equivalent to installing two identical impellers back-to-back on a shaft to work in parallel, so this kind of pump not only has large flow, but also can automatically balance the axial force. The single-stage double suction pump generally adopts a half spiral suction chamber, and the pump body is a volute type pressurized water air and horizontally split type. The bearing is installed at both ends of the pump shaft, the small pump adopts rolling bearing, and the large pump adopts sliding bearing. The pump works stably and reliably, and is easy to maintain. As long as the pump cover is opened, the whole rotor can be taken out without moving the inlet and outlet pipelines and motors.
