Ａ、定子A, stator定子是螺桿泵的一個關鍵部件，并直接影響到井下機組的壽命。定子制造質量越高，井下機組的壽命就越長。定子的作用就是提供轉子工作和液體抽汲的螺旋腔，其結構非常簡單，由鋼制外殼和塑料／橡膠襯套內(nèi)腔有雙螺旋、三螺旋、四螺旋甚至五螺旋、六螺旋，在相同尺寸下，螺旋數(shù)越多，泵的排量越高。The stator is a key component of the screw pump, which directly affects the life of the downhole unit. The higher the quality of the stator, the longer the life of the downhole unit. The role is to provide a rotor stator and liquid pumping spiral cavity drain, the structure is very simple, a steel shell and a plastic / rubber bushing cavity with double helix, three helix, four or even five, six spiral helical spiral, in the same size, the number of spiral, the displacement of the pump is high.



Ｅ、抽油桿扶正器E, sucker rod centralizer抽油桿扶正器由心軸和扶正筒組成，它接在兩根抽油桿之間，被卡在兩個抽油桿接箍之間。心軸也就是一要極短的抽油桿短節(jié)。扶正筒是一個內(nèi)孔比心軸大１ＭＭ左右的空心塑料筒，外部有四個略比油管內(nèi)徑小的扶正翼，采取澆注成型。扶正筒可以圍繞心軸轉動，防止抽油桿旋轉時與內(nèi)壁接觸而磨蝕油管，又可以讓流體通過。The sucker rod centralizer is composed of the heart shaft and the upright cylinder, which is connected between the two sucker rods and is stuck between the two sucker rod hoops. The axis of the heart is also an extremely short rod short section. The centering cylinder is a hollow plastic tube inner hole Bixin shaft around 1MM, external four slightly smaller than the diameter of the tubing centralizer wing, adopt casting. The centralizer can revolve around the axis to prevent the sucker rod from touching the inner wall when it rotates, and it can also let the fluid pass through.

污泥輸送泵多用于排放粘度較高的輸送機械。利用葉輪的水利設計減少堵塞現(xiàn)象;軸和油室的密封緊密;安裝方便減少了操作的繁瑣，并且使用方便;易于維護。

　　污泥輸送泵不僅在生活中使用方便，使用壽命也長。在規(guī)定條件下，故障運行時間不小于10000h，整機使用壽命不小于20年。

　　污泥輸送泵的發(fā)展是因為其自身的技術特點及結構的合理，給我們帶來很大程度的方便。
