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 cealizer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 cealizer 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、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.



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，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，莫诺， pumping rod cealizer make the rod center to reduce or eliminate， another reason is caused by the ecceic motion of the rotor and the rotor are not conceic， oid a day the diameter of rotary cylinder in the stator can be larger than.

单螺杆泵工作时，两端分别作用着液体的吸排压力，因此对螺杆要产生轴向推力。螺杆泵厂家建议对于压差小于10千克力/cm2的小型泵，可以采用止推轴承。此外，还通过主动螺杆的中央油孔将高压油引入各螺杆轴套的底部，从而在螺杆下端产生一个与轴向推力方向相反的平衡推力。

　　单螺杆泵和其它容积泵一样，当泵的排出口完全封闭时，泵内的压力就会上升到使泵损坏或使电动机过载的危险程度。所以，螺杆泵厂家建议使用时在泵的吸排口处，就必须设置安全阀。
