立式渣漿泵與臥式渣漿泵的結(jié)構(gòu)
如其結(jié)構(gòu)較簡(jiǎn)單，進(jìn)、出口同在一水平線(xiàn)上，可直接安裝在管道中，電機(jī)在上面，占地面積很小。壓水室一般為螺旋形蝸殼，泵本身可以沒(méi)有軸承，直接用電機(jī)軸承，對(duì)功率大的，泵本身要有自己的軸承，軸封般為機(jī)械密封，也可以用填料。
六、立式浸沒(méi)式泵
如圖2-17所示。其泵將葉輪浸沒(méi)于液體之中，啟動(dòng)時(shí)無(wú)需灌水或抽真空，使用非常方便，占地面積小， 泵的基礎(chǔ)也很小。圖2-17 為單管式的浸沒(méi)泵，即泵軸和揚(yáng)水同在一管中。在作為污水泵時(shí)，揚(yáng)水管可做成雙管式的，即泵軸在一管中，被輸送的波體在另一管中流動(dòng)，其葉輪可設(shè)計(jì)為無(wú)堵塞式的葉輪，更不易堵塞。
七、深井泵
如圖2-18所示，主要用于深井中把水提到地面上來(lái)。這種泵由于要下到深井中去，受到井徑的限制，所以是細(xì)長(zhǎng)的。深井泵一般用立式電機(jī)，裝在地面的泵座上，經(jīng)很長(zhǎng)的傳動(dòng)軸帶動(dòng)井下的葉輪轉(zhuǎn)動(dòng)，通過(guò)很長(zhǎng)的揚(yáng)水管將井水提上來(lái)。它實(shí)際也是立式浸沒(méi)式的一種，不過(guò)它的外徑要求更小，泵更長(zhǎng)。渣漿泵廠(chǎng)家
Structure of vertical slurry pump and horizontal slurry pump
Its structure is simple, the inlet and outlet are on the same horizontal line, and it can be directly installed in the pipeline, the motor is on it, and the floor area is very small. The water pressure chamber is generally a spiral volute, and the pump itself can have no bearing, and the motor bearing is directly used. For the high-power pump, the pump itself should have its own bearing, and the shaft seal is generally a mechanical seal or a packing.
Vi. vertical immersion pump
As shown in Figure 2-17. The pump submerges the impeller in the liquid, no need to fill water or vacuumize when starting, so it is very convenient to use, with small floor area and small foundation. Figure 2-17 shows a single tube submerged pump, i.e. the pump shaft and water lift are in the same tube. As a sewage pump, the water lift pipe can be made into a double pipe type, that is, the pump shaft is in one pipe, and the transported wave body flows in another pipe. The impeller can be designed as a non blocking impeller, which is more difficult to block.
VII. Deep well pump
As shown in Figure 2-18, it is mainly used to lift water to the surface in deep wells. This kind of pump is long and thin because it is going to go down to deep well and limited by well diameter. The deep well pump generally uses the vertical motor, which is installed on the pump base on the ground, drives the downhole impeller to rotate through a long drive shaft, and lifts the well water through a long lifting pipe. It is actually a vertical immersion type, but its outer diameter is smaller and the pump is longer. Slurry pump manufacturer
