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.
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.
现将在现场采用同规格的g型单螺杆泵及齿轮泵在完全相同工况条件下并在输送出口压力为1 mpa时进行了简单的对比，测量了这样两组数据:当输送重油粘度约为75×102-6m2/ s时，齿轮泵出口压力表的指针跳动幅度为±0.16，三螺杆泵出口压力表的指针跳动幅度为±0.05，双螺杆泵出口压力表的指针跳动的幅度为±0.04 ;而当输送重油粘度约为150×102-6m2/ s时，齿轮泵出口压力表的指针跳动幅度为±0.22，三螺杆泵出口压力表的指针跳动的幅度为±0.06，莫诺，双g型单螺杆泵出口压力表的指针跳动的幅度为±0.04。这说明，g型单螺杆泵在重油的输送和喷燃过程中，介质的输送压力很稳定。并且随着介质粘度的加大，g型单螺杆泵(尤其是双螺杆泵)的无脉动特点相比之下更为明显。
