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.
Ｂ、转子B, rotors转子的结构也非常简单，主体是钢制杆件，一般外涂耐磨耐蚀的铬合金材料。其作用是传递动力和写定子形成密封腔。The structure of the rotor is also very simple, the main body is steel rod, generally coated with abrasion resistant and corrosion resistant chromium alloy material. Its function is to transfer power and write the stator to form a seal cavity.Ｃ、回转筒C, rotary barrel回转筒也就是一根内径较大的油管或空心定子筒，接在定子的上部以给转子和抽油杆杆柱以较大的回旋空间，防止转子和抽油杆因偏心运动磨擦磨损油管。A rotary cylinder is also an oil tube or hollow stator barrel with larger inner diameter. It is connected to the upper part of the stator to provide larger swirl space for the rotor and sucker rod string, so as to prevent the rotor and sucker rod from attrition wear due to eccentric wear.
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 sucker rod used is commonly used as a common 1sucker rod, hollow sucker rod and continuous sucker rod, which can be determined according to the oil well.Ｇ、定子扶正器G, stator centralizer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。The stator centralizer is a cage shaped cover with a certain elasticity. Each pair is made up of two halves, large in the middle and small at both ends. The function is to make the stator middle and reduce the stator wobble.Ｈ、锚定装置H, anchoring device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 wells without packers and shallow wells with deep pumps, it is used to fix the stator, eliminate the swinging and prevent the tripping of the stator. A common anchoring device can be used.
单螺杆泵类别： 泵从大类分为两种：容积泵和流量泵。 容积泵：通过泵的传动部件形成的空腔转运流体，传动部件的转动移出流体分为往复式和旋转式两大类 流量泵：带给流体动能，流体转运和循环；不允许干运行，液面以下运转单螺杆泵特点： 1、在低转速工况下压力稳定 2、低必须气蚀余量 3、可输送含大颗粒的介质 4、可输送含磨蚀性的介质 5、压力可至48B 6、流量稳定、可用于计量加药 7、流量对介质的粘度高低影响不大 8、只有一处轴封、便于检修
