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.



Ｅ、抽油杆扶正器E， 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.



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，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。
