Ｂ、转子B, rotors转子的结构也非常简单，主体是钢制杆件，一般外涂耐磨耐蚀的铬合金材料。其作用是传递动力和写定子形成密封腔。The structure of the rotor is also very simple, the main body is steel rod, generally coated with abrasion resistant and corrosion resistant chromium alloy material. Its function is to transfer power and write the stator to form a seal c***ity.Ｃ、回转筒C, rotary barrel回转筒也就是一根内径较大的油管或空心定子筒，接在定子的上部以给转子和抽油杆杆柱以较大的回旋空间，防止转子和抽油杆因偏心运动磨擦磨损油管。A rotary cylinder is also an oil tube or hollow stator barrel with larger inner diameter. It is connected to the upper part of the stator to provide larger swirl space for the rotor and sucker rod string, so as to prevent the rotor and sucker rod from attrition wear due to eccentric wear.



Ｅ、抽油杆扶正器E, sucker rod centralizer抽油杆扶正器由心轴和扶正筒组成，它接在两根抽油杆之间，被卡在两个抽油杆接箍之间。心轴也就是一要极短的抽油杆短节。扶正筒是一个内孔比心轴大１ＭＭ左右的空心塑料筒，外部有四个略比油管内径小的扶正翼，采取浇注成型。扶正筒可以围绕心轴转动，防止抽油杆旋转时与内壁接触而磨蚀油管，又可以让流体通过。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 ***aller 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.

污泥输送泵多用于排放粘度较高的输送机械。利用叶轮的水利设计减少堵塞现象;轴和油室的密封紧密;安装方便减少了操作的繁琐，并且使用方便;易于维护。

　　污泥输送泵不仅在生活中使用方便，使用寿命也长。在规定条件下，故障运行时间不小于10000h，整机使用寿命不小于20年。

　　污泥输送泵的发展是因为其自身的技术特点及结构的合理，给我们带来很大程度的方便。
