管柱脱落是自由式管柱结构经常发生的一种现象，莫诺，这是由于正常运转时转子旋转对定子产生的摩擦扭矩方向实际上是定子及油管的连接螺纹的卸扣方向，如果摩擦力矩大于油管扣的上扣扭矩，油管就脱扣。当尾管很重时，还会出现螺纹掳扣。当管柱脱落时，通过作业重新连接好就能恢复生产。如果未发生螺纹掳扣，可以采取对扣方式打捞，如果发生掳扣，必须下打捞工具进行打捞。Columnshedding is a common phenomenon of free tube structure， which isdue to the direction of rotation of the friction torque generatedby the stator rotor during normal operation is actually a statorand tubing connection1 screw shackle direction， if the frictiontorque is greater than the pipe le on torque， oil pipe tripping.When the tail pipe is very heavy， there will also be a threadcaption. When the pipe column falls off， the production can berestored by reconnecting the work. If the le is not threaded， itcan be salvaged by the way of the le. If the le occurs， the fishingtool must be salvaged.
F、抽油杆F， sucker rod所使用的抽油杆是常用的普通抽油杆、空心抽油杆和连续抽油杆，可根据油井确定。The suckerrod used is commonly used as a common 1sucker rod， hollow suckerrod and continuous sucker rod， which can be determined according tothe oil well.G、定子扶正器G， statorcentralizer定子扶正器为有一定弹性的笼形装罩，每一对由两半构成，中间大、两端小。作用是使定子居中和减小定子的摆动。Thestator centralizer is a cage shaped cover with a certainelasticity. Each pair is made up of two halves， large in the middleand small at both ends. The function is to make the stator middleand reduce the stator wobble.H、锚定装置H， anchoringdevice对于没有封隔器的井和泵挂深度浅的井，用于固定定子、消除摆动和防止定子脱扣。采用普通的锚定装置即可。For wellswithout packers and shallow wells with deep pumps， it is used tofix the stator， eliminate the swinging and prevent the tripping ofthe stator. A common anchoring device can be used.
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，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提高液体的温度后使其粘度降低或者改用立式螺杆泵。
