渣浆泵的几种常用结构蜗壳式多级泵

采用螺旋形压水室的泵俗称蜗壳泵。泵体由几个蜗壳组成，串联工作，叫蜗壳式多级

泵。每个叶轮均有相应的螺旋形压水室，泵体采用水平中开式。 叶轮一般采用对称布置，自动平衡轴向力，进、出口都铸在泵体上。所以检修非常方便，可以不拆御进、出口管路，只要把上泵体(泵盖)打开即可取出整个转子。其缺点泵体体积大，且结构复杂，对铸造加工增加了难度。所以价格也较高，一般用于流量较大，扬程较高，运行可靠性要求较高的地方。渣浆泵厂家

Several commonly used structure of slurry pump volute type multistage pump

The pump with spiral water chamber is commonly known as volute pump. The pump body is composed of several volutes, which work in series, called volute type multistage

Pump. Each impeller has a corresponding spiral water pressure chamber, and the pump body adopts horizontal split type The impeller is generally arranged symmetrically, and the axial force is automatically balanced. The inlet and outlet are cast on the pump body. Therefore, the maintenance is very convenient. The inlet and outlet pipelines can be removed without dismantling. The whole rotor can be taken out as long as the upper pump body (pump cover) is opened. Its disadvantages are large volume and complex structure, which increase the difficulty of casting. Therefore, the price is also high, which is generally used in places with large flow, high lift and high requirements for operation reliability. Slurry pump manufacturer
