Ｅ、抽油杆扶正器E，莫诺， 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 comed 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 smaller 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.

管柱脱落是自由式管柱结构经常发生的一种现象，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。Column shedding is a common phenomenon of free tube structure， which is due to the direction of rotation of the friction torque generated by the stator rotor during normal operation is actually a stator and tubing connection1 screw shackle direction， if the friction torque is greater than the pipe le on torque， oil pipe tripping. When the tail pipe is very heavy， there will also be a thread caption. When the pipe column falls off， the production can be restored by reconnecting the work. If the le is not threaded， it can be salvaged by the way of the le. If the le occurs， the fishing tool must be salvaged.

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 small 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， avoid a day the diameter of rotary cylinder in the stator can be larger than.
