 由于吸液管道或者轴封的地方有泄漏会导致空气被吸入到单螺杆泵里面，这样单螺杆泵就会处于吸空气的状态，进口管道不能形成负压所以螺杆泵吸不上液体。处理方法是检查、修理管道，排除杂物，调整更换轴封。    单螺杆泵电机反转也会导致螺杆泵吸不上液体的现象出现，调整电机的极性接头就可以了。    抽吸的矿浆太干，莫诺，或在半干状态下运转也是螺杆泵吸不上液体的原因，这种情况只能稀释或向进料口加入充足的矿浆。    输送的液体粘度太高也会导致螺杆泵吸不上液体，如果是液体粘度太高的问题只能降低螺杆泵的转速然后提高液体的温度后使其粘度降低或者改用立式螺杆泵。

管柱脱落的故障现象是：运行电流很低，基本上是电机的空载电流，除了有一股一股的气外，井口基本上无产液，正发循环时油套连通。The failure phenomenon of the string is: the running current is very low， basically the motor's no load current. Besides the gas with a single strand of gas， the wellhead basically has no liquid production， and the oil sleeve is connected when circulating.减少管柱脱落的措施有：将油管上扣扭矩由原来的值提高到值；采用油管螺纹垫片；定子上的装卸短节采用防松螺纹连接；采用油管锚或张力封隔器固定螺杆泵。The measures to reduce the falling off of the pipe string are as follows: increase the torque from the original value to the maximum value; use the oil pipe screw gasket; the loading and unloading joint on the stator is connected by loosening screw thread; and use the oil pipe anchor or tension packer to fix the screw pump.

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.
