Problems solved by technology
[0003] In the existing vane pump, the vane is ejected by spring force during operation. In actual use, we found that this mode of operation brings limitations to the high-speed operation of the vane pump. Affected by the response speed of the spring, it will If the blades are not ejected in time, the blades will be separated from the inner wall of the pump oil chamber, which will seriously affect the balance in the pump body and affect the oil delivery efficiency

Embodiment Construction
[0023] see Figure 1-6 , the present invention provides a technical solution: a vane pump with concave vanes, including a stator 1, a rotor 2 and a cover 3, the rotor 2 is located in the pump oil chamber 4 opened on the stator 1, and the edge of the stator 1 is opened There are positioning holes 5, a shaft hole 6 is opened in the middle of the rotor 2, the axis of the shaft hole 6 coincides with the axis of the stator 1, and the outer wall of the rotor 2 is provided with four blade mechanisms 7 arranged in a circle with the axis of the rotor 2 as a reference. The cover 3 is attached to the back of the stator 1 , and a pressurizing mechanism 8 is also arranged in the stator 1 .
[0024] The vane mechanism 7 includes a vane slot 71, a vane 72, and a spring 73. The four vane slots 71 are arranged in a ring on the outer side wall of the rotor 2. The vane 72 is inserted into the vane slot 71, and the vane 72 is close to the bottom wall of the vane slot 71. One side of the spring 7...

The invention belongs to the technical field of vane pumps and discloses a vane pump with concave vanes. The vane pump with inner concave vanes includes a stator, a rotor and a cover. The rotor is located in the pump oil chamber opened on the stator. A positioning hole is opened on the edge of the stator. A shaft hole is opened in the middle of the rotor. The shaft of the shaft hole is The center coincides with the axis of the stator, and the outer wall of the rotor is provided with four blade mechanisms arranged in a ring with the rotor axis as a reference. The vane pump with inner concave vanes converts the pressure in the pump oil chamber into thrust through the pressurizing mechanism. With the movement of the oil in the pump oil chamber, on the one hand, it exerts a rotational impact on the rotor, and on the other hand, the oil is pressed into the The oil supply gap accelerates the ejection of the vane, which greatly improves the oil delivery efficiency of the vane pump.
Description
technical field [0001] The invention relates to the technical field of vane pumps, in particular to a vane pump with concave vanes. Background technique [0002] The vane pump is a pump in which the vanes in the rotor groove are in contact with the pump casing, and the sucked liquid is pressed from the oil inlet side to the oil discharge side. [0003] In the existing vane pump, the vane is ejected by spring force during operation. In actual use, we found that this mode of operation brings limitations to the high-speed operation of the vane pump. Affected by the response speed of the spring, it will If the blades are not ejected in time, the blades will be detached from the inner wall of the pump oil chamber, which will seriously affect the balance in the pump body and affect the oil delivery efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a vane pump with recessed vanes. The vane pump with recessed vanes converts the pres...
