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&the rotor.油管与抽油杆柱磨损oil pipe&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消除，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&-er rod wear reason is because the deviation of -er rod attached to the tubing wall caused by heating, pumping rod centralizer make the rod cct to reduce/eliminate, another reason is caused by the eccentric motion of the rotor&the rotor are not concentric, avoid a day the diameter of rotary cylinder in the stator can be larger than.
ｄ、限位器d, limiting device限位器为一个底部带限位板和流-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&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&lose its function&prevent the rod from falling into the bottom when the rod string falls off.
ｅ、抽油杆扶正器e, -er 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 -er rod centralizer is co-ed of the heart shaft&the upright cylinder, which is connected between the two -er rods&is stuck between the two -er rod hoops. the axis of the heart is also an extremely short rod short section. the ccting 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 -er rod from touching the inner wall when it rotates,&it can also let the fluid pass through.
由于吸液管道或者轴封的地方有泄漏会导致空气被吸入到单螺杆泵里面，这样单螺杆泵就会处于吸空气的状态，进口管道不能形成负压所以螺杆泵吸不上液体。处理方法是检查、修理管道，排除杂物，调整更换轴封。 单螺杆泵电机反转也会导致螺杆泵吸不上液体的现象出现，调整电机的极性接头就可以了。 抽吸的矿浆太干，或在半干状态下运转也是螺杆泵吸不上液体的原因，这种情况只能稀释或向进料口加入充足的矿浆。 输送的液体粘度太高也会导致螺杆泵吸不上液体，如果是液体粘度太高的问题只能降低螺杆泵的转速然后提高液体的温度后使其粘度降低或者改用立式螺杆泵。
