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，莫诺， 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。

Ｄ、限位器D， limiting device限位器为一个底部带限位板和流通通道的短节，接在定子的尾部，其作用是施工作业时给转子限位以防止下入过头而失去作用和杆柱脱落时防止杆柱掉入井底。The limiting device is a short section with bottom limit plate and distribution channel， which is connected to the tail of the stator. Its function is to limit the rotor to the rotor during ctruction1， so as to prevent it from falling into the overhead and lose its function and prevent the rod from falling into the bottom when the rod string falls off.
