Abstract

The invention discloses an energy-saving vane pump which comprises a main pump and an oil circuit block, wherein the main pump is composed of a cam stator, a rotor, a rotor core shaft, vanes, vane root oil cavities, a back cover and a front shell; a first vane pressure oil mouth is formed in the front shell; the oil circuit block is composed of a second vane pressure oil mouth; and the first vane pressure oil mouth is connected with the second vane pressure oil mouth and communicates with the vane root oil cavities. In the working process, the energy-saving vane pump can continuously convey oil liquid to the vane root oil cavities through the oil circuit block to push out the vanes, so that the problems of the vane pump of poor self-sucking capacity and limitation of lowest rotational speed requirement are effectively solved. Meanwhile, according to the energy-saving vane pump, as the rotational speed of a motor is lowered, the electricity can be directly saved, the oil suction quantity of the vane pump is also reduced, overflow loss of the vane pump and the temperature of the oil liquid are both lowered, and the energy can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of vane pumps, in particular to an energy-saving vane pump. Background technique [0002] Vane pumps are widely used in machine tools, automobile steering systems and construction machinery due to their advantages of uniform flow, stable operation, small size and light weight. A big defect of the vane pump is the poor self-priming ability, and the throwing of the vane depends on the centrifugal force at high speed, which makes the vane pump have a minimum speed requirement for application. Generally, the minimum speed of the vane pump should not be lower than 500rpm. In the case of low motor speed, people have to use other types of hydraulic pumps. At the same time, in some hydraulic systems that can use high and low speed conversion, due to the minimum speed limit of the vane pump, people have to use high speed all the time, thus wasting energy.
