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.

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 plastic 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.

单螺杆泵的使用方法:

单螺杆泵在发达国家已广泛使用，德国称“偏心转子泵”。由于其单螺杆泵在发达国家已广泛使用，德国称“偏心转子泵”。由于其优良的性能，在国内的应用范围也在迅速扩大。它的特点是对介质的适应性强、流量平稳、压力脉动小、自吸能力高，这是其它任何泵种所不能替代的。

单螺杆泵使用方法,螺杆泵使用注意事项：

1、启动螺杆泵前还得必须先确定螺杆泵的运转方向，单螺杆泵不能反转。

2、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。

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。
