1、单螺杆泵严禁在泵腔无液体的情况下空运转,必须在启动前由泵进口把液体注入泵体后再启动螺杆泵,以免空转磨损螺杆泵定子。
2、启动单螺杆泵前还得必须先确定螺杆泵的运转方向,螺杆泵不能反转。
3、新安装或长时间停泵数天后的单螺杆泵,不能立即起动,也应该向泵体注入适量润滑剂或螺杆泵输送的液体,再用管子钳扳动螺杆泵几转后才可以起动。
4、不锈钢螺杆泵输送高粘度的液体或含有腐蚀性的介质后,应该用清水或者溶剂进行冲洗螺杆泵泵腔,防止堵塞以免造成下次起动螺杆泵时困难而损坏定子。
5、冬天使用单螺杆泵温度偏低不使用时应该排除泵体积液,防止泵体冻裂或者泵内结冰下次起动时拉坏定子。
6、使用过程中轴承箱内应定期加润滑油,发现轴端有渗流时,要及时处理或调换油封。
7、在运行中如发生异常情况,应立即停泵检查原因,排除故障。

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,莫诺转子,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.

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, 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.
