With the screw rotation and meshing, the sealed space in the pump suction side evolving to inhalation chamber inclose one of the liquid, and from inhalation of room along the screw axis moved continuously push from client, will be closed in the space continuous discharge of liquid, like a nut in the thread when he was constantly turning the situation to move forward, this is the basic working principle of the screw pump.

随着螺杆的转动和啮合，这些密封空间在泵的吸入端不断形成，将吸入室中的液体封入其中，并自吸入室沿螺杆轴向连续地推移至排出端，将封闭在各空间中的液体不断排出，犹如一螺母在螺纹回转时被不断向前推进的情形那样，这就是螺杆泵的基本工作原理。

Studied pumping well system in this article, the intermediate power transmission parts uesed flexible rod, the downhole assembled rod pump, the ground driving device would transform up and down reciprocating motion into rotating motion. With own mechanism rounded trip for the downhole flexible rod and pump. Wellhead polished rod changed common stell for flexible polished rod. It was a innovation in theory study and craftwork method. It was a remarkable feature in this article, because these innovations were not studied and attempted for prehuman.

本文所研究的抽油系统，中间动力传动部件采用柔性抽油杆，井下配套杆式抽油泵，其地面驱动装置将传统抽油机驴头的上下往复运动变为旋转运动，并且能够利用自身结构对井下柔性抽油杆及泵体实现起下作业，井口光杆也由普通钢质光杆变为柔性光杆，这是理论研究和工艺方法的创新，这些创新都是前人所没有研究和尝试的，是本文的一大显著特点。

In order to do research on pipe flow and pump characteristics of polymer flooding and water flooding rod-pumped well in especially high water-cut stage, rheometric test aimed at production stream from polymer flooding and water flooding rod-pumped well in especially high water-cut stage has been made, and the characteristic of production stream in especially high water-cut stage is confirmed as Newtonian fluid. Experiments using different mediums about pipe flow and pump characteristics is made. Frictional resistance and coefficient of friction resistance of annulus fluid between sucker rod and the pipe flow is calculated under different working conditions. Frictional resistance between plunger and pump barrel under different parameters is calculated based on related theory of pump characteristic and the strained analytical model of oil-well pump. Besides, using the theory of slit flow and hydraulic -clamping pressure, the frictional resistance is calculated, and the error between the result and measured value is no more than 13%.

为研究特高含水期水驱及聚驱抽油机井管流特性与泵特性，本文针对特高含水期水驱及聚驱井采出液进行了流变性试验，确定了特高含水期油井采出液的性质属牛顿流体；利用不同介质，进行管流特性与泵特性试验，得到了不同工况下杆、管环空流的摩擦阻力和摩阻系数；根据泵特性相关理论和抽油泵受力分析模型，计算了不同参数下柱塞与泵筒间的摩擦阻力，并利用缝隙流与液压卡紧力理论对柱塞与泵筒间的摩擦阻力进行了计算，计算结果与实测值误差在13%以内。

The major products include: KCB, 2CY, YCB gear pump, 3 G, 2WW, G-type screw pump, LB freezer for pumps, CYZ centrifugal pumps, NYP high viscosity pump, RY conducting oil pump, F stainless steel pumps, LQCB asphalt pump, AY centrifugal pumps, and so on.

The conveyed medium can't be leaked outside. Thus it will not cause the environmental pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium. 5、No electricity. It's safe and reliable while using in the flammable and explore places. 6、It can be soaked in medium. 7、It's convenient to use and reliable to work. Only open or close the gas valve body while starting or stopping. Even if no medium operation or pausing suddenly for long time because of accident matters, the pump will not be damaged caused by this. Once over-loading, the pump will automatically stop and possesses the self-protection function. When the load recovers normally, it also can start automation. 8、Simple structure and less wearing parts. This pump is simple in structure, installation and maintenance. The medium conveyed by the pump will not touch the matched pneumatic valve and coupling lever etc. not like other kinds pumps, the performance will drop down gradually because of the damages of rotor, gear and vane etc. 9、It can transmit the adhesive liquid (the viscosity is below 10000centipoise) 10、 This pump needn't the oil lubricant. Even if idling, it has any influence to the pump. This is a characteristic of this pump.

所以抽送有毒、易挥发或腐蚀性介质时，不会造成环境污染和危害人身安全； 5、不必用电，在易燃、易爆场所使用安全可靠 6、可以浸没在介质中工作 7、使用方便、工作可靠、开停只需简单地打开和关闭气体阀门，即使由于意外情况而长时间无介质运行或突然停机，泵也不会因此而损坏，一旦超负荷，泵会自动地停机，具有自我保护性能，当负荷恢复正常后，又能自动启动运行； 8、结构简单、易损件少，该泵结构简单，安装、维修方便，泵输送的介质不会接触到配气阀，联杆等运动部件，不像其他类型的泵因转子、活塞、齿轮、叶片等部件的磨损而使性能逐步下降； 9、可输送较粘的液体（粘度在1万博以下）； 10、本泵无须用油润滑，即使空转，对泵也无任何影响，这是该泵一大特点
