杆柱脱落rod shedding杆柱脱落也是螺杆泵常发生的一种故障现象,表现为运行电流很低,井口也无产液,正反循环油套不连通,通过对扣或下入抽油杆打捞工具就可以进行处理来恢复生产。抽油杆脱落也有两种情况,莫诺定子,一是脱扣,一是掳扣。造成脱扣的原因是停机后抽油杆柱扭转变形余能释放引起杆柱反转,可以采取在地面和抽油杆柱上安装防倒装置进行防止。造成杆柱掳扣的原因有三个:一个是稠油井在长时间关井后再启泵时,启动扭矩---大,把螺纹损坏了;一个是油---稠,螺杆泵长期在高扭矩下工作而把螺纹损坏;再有一个原因是定子部分脱胶,转子转不动造成的。

b、转子b, rotors转子的结构也非常简单,主体是钢制杆件,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 ---, the main body is steel rod, generally coated with abrasion resistant&corrosion resistant chromium alloy material. its function is to transfer power&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/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&---er rod string, so as to prevent the rotor&---er rod from attrition wear due to eccentric wear.

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 ws= 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.
