The premature wear of the fixed rotor is mainly caused by the small 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, avoid a day the diameter of rotary cylinder in the stator can be larger than.
211G型单螺杆泵可无脉动地工作 G型单螺杆泵工作时,莫诺定子,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。
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 cavity drain, the structure is very simple, a steel shell and a plastic / rubber bushing cavity 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.
