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，莫诺，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.
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，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。
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 stic 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.
