Ｄ、限位器D， limiting device限位器为一个底部带限位板和流通通道的短节，接在定子的尾部，其作用是施工作业时给转子限位以防止下入过头而失去作用和杆柱脱落时防止杆柱掉入井底。The limiting device is a short section with bottom limit plate and distribution channel， which is connected to the tail of the stator. Its function is to limit the rotor to the rotor during ctruction1，莫诺， so as to prevent it from falling into the overhead and lose its function and prevent the rod from falling into the bottom when the rod string falls off.

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。

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 cavity.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.
