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，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。



Ｅ、抽油杆扶正器E， sucker rod centralizer抽油杆扶正器由心轴和扶正筒组成，它接在两根抽油杆之间，被卡在两个抽油杆接箍之间。心轴也就是一要极短的抽油杆短节。扶正筒是一个内孔比心轴大１ＭＭ左右的空心塑料筒，外部有四个略比油管内径小的扶正翼，采取浇注成型。扶正筒可以围绕心轴转动，防止抽油杆旋转时与内壁接触而磨蚀油管，又可以让流体通过。The sucker rod centralizer is comed of the heart shaft and the upright cylinder， which is connected between the two sucker rods and is stuck between the two sucker rod hoops. The axis of the heart is also an extremely short rod short section. The centering cylinder is a hollow plastic tube inner hole Bixin shaft around 1MM， external four slightly smaller than the diameter of the tubing centralizer wing， adopt casting. The centralizer can revolve around the axis to prevent the sucker rod from touching the inner wall when it rotates， and it can also let the fluid pass through.



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，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 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.
