Brief description of the drawings
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:
Fig. 1 is the structural representation of the utility model low noise pin-type load high pressure vane pump embodiment;
Fig. 2 is the structural representation of blade.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, be the structural representation of the utility model low noise pin-type load high pressure vane pump embodiment. The low noise pin-type load high pressure vane pump of the present embodiment, comprise pump case 1, in pump case 1, be provided with and be fixed with stator 2 and be arranged on the rotor 3 in stator 2, rotor 3 suits are arranged on pump case 1 and rotate in the rotating shaft 4 coordinating, the two ends of stator 2 are respectively equipped with the oil suction oil distribution casing 5 and the oil extraction oil distribution casing 6 that are fixedly connected with it, be provided with oil-sucking hole 7 and outage 8 corresponding to oil suction oil distribution casing 5 and oil extraction oil distribution casing 6 respectively on pump case 1. On the periphery wall of rotor 3, annular is laid with radial slot 9, the bottom surface of radial slot 9 is provided with radial hole, and the bottom of radial hole is provided with annular grease chamber 10, is provided with pin 11 in radial hole, in radial slot 9, be provided with blade 12, the blade 12 of the present embodiment adopts low noise pin-type load high pressure vane pump blade.
Concrete, the low noise pin-type load high pressure vane pump blade of the present embodiment comprises blade body 13, the end face that blade body 13 coordinates with stator 2 inner surfaces is provided with logical oily groove 14, the two side of logical oily groove 14 forms two and alternately contacts the contact lip 15 coordinating with stator 2 inner surfaces, and is provided with the oil through 16 that leads to blade body 13 bottom surfaces in logical oily groove 14. The end face of the contact lip 15 of the present embodiment is arc surface.
The low noise pin-type load high pressure vane pump of the present embodiment, by logical oily groove being set on the end face of its blade and in the bottom surface of logical oily groove, oil through being set, the oil pressure of blade end face and bottom surface is in high pressure transient equilibrium, the region that no matter blade contacts with stator inner surface is oil suction region or oil extraction region or transitional region, can ensure that blade presses close to all the time stator inner surface and not interfered by external force; Meanwhile, can reduce the pressure reduction between root of blade and top, and then reduce the contact gear ratio pressure of blade to stator inner surface, can reduce the wearing and tearing between blade and stator inner surface, improve service life. The blade of the present embodiment has also adopted two alternately to contact the contact lip coordinating with stator inner surface, and two contact lips alternately contact cooperation respectively with stator inner surface, can further reduce the wearing and tearing of blade end face, improve service life.
