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 ***all gap between the fixed rotor and the rotor.油管与抽油杆柱磨损Oil pipe and 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 and sucker rod wear reason is because the deviation of sucker rod attached to the tubing wall caused by heating, pumping rod centralizer make the rod center to reduce or eliminate, another reason is caused by the eccentric motion of the rotor and the rotor are not concentric, ***oid a day the diameter of rotary cylinder in the stator can be larger than.



Ａ、定子A, stator定子是螺杆泵的一个关键部件，并直接影响到井下机组的寿命。定子制造质量越高，井下机组的寿命就越长。定子的作用就是提供转子工作和液体抽汲的螺旋腔，其结构非常简单，由钢制外壳和塑料／橡胶衬套内腔有双螺旋、三螺旋、四螺旋甚至五螺旋、六螺旋，在相同尺寸下，螺旋数越多，泵的排量越高。The stator is a key component of the screw pump, which directly affects the life of the downhole unit. The higher the quality of the stator, the longer the life of the downhole unit. The role is to provide a rotor stator and liquid pumping spiral c***ity drain, the structure is very simple, a steel shell and a plastic / rubber bushing c***ity with double helix, three helix, four or even five, six spiral helical spiral, in the same size, the number of spiral, the displacement of the pump is high.



 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。
