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.
Ｆ、抽油杆F, sucker 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 sucker rod used is commonly used as a common 1sucker rod, hollow sucker rod and continuous sucker 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 and small at both ends. The function is to make the stator middle and reduce the stator wobble.Ｈ、锚定装置H, anchoring device对于没有封隔器的井和泵挂深度浅的井，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 and shallow wells with deep pumps, it is used to fix the stator, eliminate the swinging and prevent the tripping of the stator. A common anchoring device can be used.
单螺杆泵类别： 泵从大类分为两种：容积泵和流量泵。 容积泵：通过泵的传动部件形成的空腔转运流体，传动部件的转动移出流体分为往复式和旋转式两大类 流量泵：带给流体动能，流体转运和循环；不允许干运行，液面以下运转单螺杆泵特点： 1、在低转速工况下压力稳定 2、低必须气蚀余量 3、可输送含大颗粒的介质 4、可输送含磨蚀性的介质 5、压力可至48B 6、流量稳定、可用于计量加药 7、流量对介质的粘度高低影响不大 8、只有一处轴封、便于检修
