　1、单螺杆泵严禁在泵腔无液体的情况下空运转，必须在启动前由泵进口把液体注入泵体后再启动螺杆泵，以免空转磨损螺杆泵定子。

　　2、启动单螺杆泵前还得必须先确定螺杆泵的运转方向，螺杆泵不能反转。

　　3、新安装或长时间停泵数天后的单螺杆泵，不能立即起动，也应该向泵体注入适量润滑剂或螺杆泵输送的液体，再用管子钳扳动螺杆泵几转后才可以起动。

　　4、不锈钢螺杆泵输送高粘度的液体或含有腐蚀性的介质后，应该用清水或者溶剂进行冲洗螺杆泵泵腔，防止堵塞以免造成下次起动螺杆泵时困难而损坏定子。

　　5、冬天使用单螺杆泵温度偏低不使用时应该排除泵体积液，防止泵体冻裂或者泵内结冰下次起动时拉坏定子。

　　6、使用过程中轴承箱内应定期加润滑油，发现轴端有渗流时，要及时处理或调换油封。

　　7、在运行中如发生异常情况，应立即停泵检查原因，排除故障。

B、转子B， rotors转子的结构也非常简单，主体是钢制杆件，莫诺定子，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.



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.
