摘　　要：摆动转子气液混输泵工作时 ,偏心曲轴旋转使转子沿缸体外定子与内定子之间的环形空间做摆转运动 ,转子外壁与缸体外定子、转子内孔与内定子外径分别同隔板一起形成两个吸入腔和两个排出腔 ,吸入腔与排出腔的容积随转子摆动不断发生周期性变化 ,完成介质的吸入和排出。内、外定子与转子在工作时互不接触 ,保持一定的间隙 ,泵采用专门的润滑系统 ,润滑轴承及机械密封。这种泵用于油田的油、气、水多相混输 ,可有效降低井口压力 ,提高油井产量。The design feature of the gas-liquid delivery pump with swing rotor is described. Inner and outside stators are fixed respectively in the left and right cylinder of the pump, and they form two suction chambers and two discharge chamber along with the rotor and the division plate. The rotor linked with the eccentric craftshaft through bearing. When in operation, the inner and outside stators and the rotor are kept away from each other with a certain gap. Special lubrication system is adopted for lubricating the bearing and mechanical seal. The working principle of the pump is expounded and the application of the pump are introduced.
