Problems solved by technology

But the disadvantage is that the top of the blade and the stator are sliding friction, the force performance of the contact surface is poor, and the friction force is relatively large when the blade is running, which is likely to cause severe wear and system noise between the blade and the stator.

Abstract

The invention discloses a high-efficiency energy-saving vane pump leaf structure, which comprises a pump vane body, and is characterized in that: the pump vane body top is provided with a rolling groove, the left side of the rolling groove is provided with a supporting hole, the right side of the rolling groove is provided with a thread hole, the rolling groove is internally provided with a rolling body, successively passes through the threaded hole and the rolling body via pins to be connected with the supporting hole, and is connected with the thread hole through a screw, the rolling body is fixed in the rolling groove and at the both ends of thee supporting hole and the threaded hole; the pump vane body is internally provided with a square groove cavity; the groove cavity is internally provided with a spring; the groove cavity area accounts for 3 / 4 of the pump vane body area; and the supporting hole and the thread hole are in a same axis. The high-efficiency energy-saving vane pump leaf structure can effectively improve the efficiency, reduce noise, reduce energy consumption, increase the vane pump rotor rotation speed, improve the flow rate, improve the spring pressure of the vane bottom, increase normal pressure of a vane and a stator hook face, and improve the sealing ability of a hydraulic seal cavity and the volumetric efficiency of a vane pump.

Description

technical field [0001] The invention relates to a pump component, in particular to a pump vane structure of a high-efficiency and energy-saving vane pump. Background technique [0002] In the field of hydraulic transmission technology, the vane pump is the most widely used hydraulic pump in the industry. The important indicators to measure the performance of the vane pump are mainly the vibration and noise of the pump. In recent years, domestic and foreign universities and research institutes have carried out a lot of research on the noise reduction of vane pumps, and achieved certain results. With the development of vane pumps in the direction of high pressure and high speed, the noise and vibration problems of domestic vane pumps after running for a long time are still prominent and have not been well solved. The vibration and noise lead to a large amount of energy loss and reduce the efficiency of the hydraulic system . [0003] The noise of the vane pump is composed o...
