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.



定转子过早磨损Premature wear of fixed rotor定转子过早磨损主要是由于定转子的间隙过小引起的。The premature wear of the fixed rotor is mainly caused by the ***all gap between the fixed rotor and the rotor.油管与抽油杆柱磨损Oil pipe and rod string wear油管与抽油杆柱磨损的原因一是因为井斜抽油杆贴在油管壁上引起的，可以通过加抽油杆扶正器使抽油杆柱居中来减轻或消除，另一个原因是定转子不同心及转子的偏心运动造成的，在定子以上加一节内径较大的回转筒即可避免。Tubing and sucker rod wear reason is because the deviation of sucker rod attached to the tubing wall caused by heating, pumping rod centralizer make the rod center to reduce or eliminate, another reason is caused by the eccentric motion of the rotor and the rotor are not concentric, ***oid a day the diameter of rotary cylinder in the stator can be larger than.



 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，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。
