阅读说明：本技术 回转型叶片泵 (Rotary vane pump ) 是由 张龙兆 于 2018-07-04 设计创作，主要内容包括：本发明涉及一种叶片式转子泵及马达的技术领域。该回转型叶片泵,其特征包括内转子(2)、外转子(3)、叶片(4)、叶片内转子轴(5)、叶片外转子轴(6)、月牙形空腔(11)。叶片(4)径向两端各有一个叶片内转子轴(5)和叶片外转子轴(6),叶片内转子轴(5)嵌入在内转子轴孔内,叶片外转子轴(6)嵌入在外转子轴孔内。内转子(2)和外转子(3)、叶片(4)相互牵着转动,叶片(4)的打开是靠内、外转子轴孔牵动叶片内转子轴(5)、叶片外转子轴(6)实现。内转子(2)与外转子(3)形成平行轴,并形成月牙形空腔(11)。该发明具有叶片双端轴铰链、高转速、高密封、高效率、功率体积比大等优点。(The invention relates to the technical field of a vane type rotor pump and a motor. The rotary vane pump is characterized by comprising an inner rotor (2), an outer rotor (3), vanes (4), a vane inner rotor shaft (5), a vane outer rotor shaft (6) and a crescent cavity (11). The radial two ends of each blade (4) are respectively provided with a blade inner rotor shaft (5) and a blade outer rotor shaft (6), the blade inner rotor shaft (5) is embedded in the inner rotor shaft hole, and the blade outer rotor shaft (6) is embedded in the outer rotor shaft hole. The inner rotor (2), the outer rotor (3) and the blades (4) are mutually dragged to rotate, and the blades (4) are opened by dragging the inner rotor shaft (5) and the outer rotor shaft (6) of the blades through shaft holes of the inner rotor and the outer rotor. The inner rotor (2) and the outer rotor (3) form parallel shafts and form a crescent cavity (11). The invention has the advantages of blade double-end-shaft hinge, high rotating speed, high sealing, high efficiency, large power-volume ratio and the like.)
