f、抽油杆f, ---er rod所使用的抽油杆是常用的普通抽油杆、空心抽油杆和连续抽油杆,可根据油井确定。the ---er rod used is commonly used as a common 1---er rod, hollow ---er rod&continuous ---er rod, which can be determined according to the oil well.g、定子扶正器g,mono, stator centralizer定子扶正器为有一定弹性的笼形装罩,每一对由两半构成,中间大、两端小。作用是使定子居中和减小定子的摆动。the stator centralizer is a cage shaped cover with a certain elasticity. each pair is made up of two halves, large in the middle&small at both ends. the function is to make the stator middle&reduce the stator wobble.h、锚定装置h, anchoring device对于没有封隔器的井和泵挂---浅的井,用于固定定子、消除摆动和防止定子脱扣。采用普通的锚定装置即可。for wells without packers&shallow wells with deep pumps, it is used to fix the stator, eliminate the swinging&prevent the tripping of the stator. a common anchoring device can be used.
单螺杆泵有以下优点:
1)因为泵内的回转部件惯性力较低,故可使用---的转速;
2)结构坚实,安装保养容易;
3)单螺杆泵的压力和流量范围宽阔。压力约在3.4-340千克力/cm2,流量可达18600cm3/分;
4)单螺杆泵的吸入性能好,具有自吸能力;
5)与其它回转泵相比,对进入的气体和污物不太敏感;
6)流量均匀连续,振动小,噪音低;
7)单螺杆泵的运送液体的种类和粘度范围宽广。
单螺杆泵的缺点是,螺杆的加工和装配要求较高;泵的性能对液体的粘度变化比较敏感。
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.
