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.



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.



211G型单螺杆泵可无脉动地工作 　　G型单螺杆泵工作时，通过螺杆转子与泵套的孔壁间形成的一个个密封腔，平稳地从低压区运送到高压区，在整个运送过程中，介质作纯轴向运动，可完全做到无脉动地运送介质。这一点与齿轮泵不同。齿轮泵工作时，莫诺转子，在齿轮的转动下，介质作轴向与径向及其复合方向的运动，产生明显的搅拌现象。其输出压力的表现形式:G型单螺杆泵的输出压力比较稳定，齿轮泵则出口压力会有波动。这一点在输送高粘度的介质(如重油等)时比较突出。
