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，莫诺，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.
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&liquid pumping spiral cavity drain， the structure is very ---， a steel shell&a plastic / rubber bushing cavity with double helix， three helix， four/even five， six spiral helical spiral， in the same size， the number of spiral， the displacement of the pump is high.
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.
