Problems solved by technology

[0003] When the rotor in the vane pump is moving, the vane is ejected by the spring. In the working environment where the rotor is running at high speed, it is often difficult to make the vane spring in time by relying on the elastic force of the spring alone. The high-pressure environment is unstable, which seriously affects the oil delivery efficiency of the vane pump, and urgently needs to be solved

Embodiment Construction

[0028] see Figure 1-9 , the present invention provides a technical solution: a high-speed common rail vane pump, including a stator 1, a rotor 2, an end cover 3 and a bottom plate 4, the rotor 2 is located in the eccentric hole 5 opened on the stator 1, and the outer wall of the rotor 2 There are four vane mechanisms 6 arranged circularly with the center of the rotor 2 as a reference, and the bottom plate 4 and the end cover 3 are symmetrically attached to the upper and lower surfaces of the stator 1 respectively.

[0029] The vane mechanism 6 includes a vane groove 61, a vane 62, a spring 63 and an arc bearing groove 64. The four vane grooves 61 are arranged in an annular arrangement on the outer side wall of the rotor 2. The vane 62 is inserted into the vane groove 61, and the arc The shape bearing groove 64 is offered at the side of the blade 62 near the bottom wall of the blade groove 61, and the bottom wall of the spring groove 65 provided in the middle of the arc bearin...

Abstract

The invention belongs to the technical field of vane pumps and discloses a high-speed common rail vane pump. The high-speed common rail vane pump includes a stator, a rotor, an end cover and a bottom plate. The rotor is located in an eccentric hole opened on the stator. The outer wall of the rotor is provided with four vane mechanisms arranged in a ring with the center of the rotor as a reference. , the bottom plate and the end cover are symmetrically attached to the upper and lower surfaces of the stator respectively. The high-speed common rail vane pump improves the vane. By opening an arc-shaped load-bearing groove on the vane and cooperating with the oil supply of the first and second ring grooves when the vane pump is running, the high-pressure oil can be used to push the vane, so that When the rotor rotates at high speed, the vane can pop out quickly, which improves the high-speed performance of the vane pump, keeps the contact between the vane and the wall of the eccentric hole, and 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 high-speed common rail vane pump. 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] When the rotor in the vane pump moves, the vane is ejected by the spring, but in the working environment where the rotor is running at high speed, it is often difficult to make the vane spring in time by relying on the elastic force of the spring alone. The high-pressure environment is unstable, which seriously affects the oil delivery efficiency of the vane pump, and urgently needs to be solved. Contents of the invention [0004] The object of the present invention is to provide a high-speed common rail vane pump, which has both high and low speed operation performance and greatly improves the oil delivery efficiency. ...
