渣漿泵的幾種常用結(jié)構(gòu)蝸殼式多級泵
采用螺旋形壓水室的泵俗稱蝸殼泵。泵體由幾個蝸殼組成，串聯(lián)工作，叫蝸殼式多級
泵。每個葉輪均有相應的螺旋形壓水室，泵體采用水平中開式。 葉輪一般采用對稱布置，自動平衡軸向力，進、出口都鑄在泵體上。所以檢修非常方便，可以不拆御進、出口管路，只要把上泵體(泵蓋)打開即可取出整個轉(zhuǎn)子。其缺點泵體體積大，且結(jié)構(gòu)復雜，對鑄造加工增加了難度。所以價格也較高，一般用于流量較大，揚程較高，運行可靠性要求較高的地方。渣漿泵廠家
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
