The inner surface of the stator is composed of two large arcs R2, small arcs R1 and four transition curves (1,2, 3, 4). The stator and rotor are concentric. The four oil distribution windows on the oil distribution pan communicate with the suction and pressure ports, respectively. When the rotor rotates clockwise, the blade embedded in the rotor slot (which can be flexibly slid) is under the action of centrifugal force and pressure oil, and the top is tightly attached to the inner surface of the stator. In this way, the stator, the rotor, the slidable blades, and the oil distribution plate constitute a plurality of closed working chambers with variable volumes. In the upper right corner and the lower left corner, the volume of the sealed working chamber gradually increases, which is an oil suction area; in the lower right corner and the upper left corner, the volume of the sealed working chamber gradually decreases, which is an oil pressure region. An oil seal area between the oil suction area and the oil pressure area separates them. Each time the rotor rotates once, each blade slides back and forth twice, and the volume of each closed working volume is circulated twice, and the size is increased and decreased twice. , To complete the role of the pump, called a double-acting vane pump. In addition, the pump's inlet oil chamber and outlet pressure oil chamber are radially opposite, so the rotor is hydraulically balanced, and the bearing is not subject to hydraulic load. Long life can be guaranteed. The rotor rotates once, and the oil is sucked twice between the two blades, and the oil is drained twice, each time the volume is M; when the number of blades is z, the displacement of all the blades of all the leaves in a week is 2Z M volumes, if the blade geometric dimensions are not taken into account, This value is exactly twice the ring volume. The average flow is: Where: R —— long radius of stator r—— short stator radius B ——Rotor thickness h Zhejiang Yongling Hydraulic Machine Co , Ltd . specializes in the production and supply of Fixed Vane Pumps in China.
