Abstract
The present invention discloses a kind of vane pump, it is characterised in that including blade（1）, blade（1）Top is adjacent in stator（2）On inner surface, inlet port（3）With press oil port（4）It is located at vane pump both ends, stator respectively（5）In vane pump center.The beneficial effects of the invention are as follows：Indivedual blade activities are dumb, as oil viscosity is excessive, may result in blade slided in rotor slot it is dumb.Blade is changed to graphite material, the wear-resisting greasy property of graphite is fine, causes neck without worrying that blade is stained with fluid.The generation of problem failure is reduced using graphite vanes, increases production efficiency.
Description
Technical field
The present invention relates to mechanical field, more particularly, to a kind of vane pump.
Background technology
Vane pump, be that the blade in rotor slot is in contact with pump case (track ring), by the liquid of suction from oil-feed side pressure to
The pump of oil extraction side.When blade pump rotor rotates, for blade in the presence of centrifugal force and pressure oil, tip is close to stator inner surface
On.The swept volume that two such blade is formed with rotor and stator inner surface, it is first descending again after ascending oil suction
Oil extraction, when blade rotates a circle, complete an oil suction and oil extraction.
The content of the invention
The present invention provides a kind of vane pump for this to solve present problems, it is characterised in that including blade,
Vane tip is adjacent on stator inner surface, and inlet port is located at vane pump both ends respectively with press oil port, and stator is in vane pump
Centre.
Preferably, the blade is graphite material.
The beneficial effects of the invention are as follows：
Indivedual blade activities are dumb, as oil viscosity is excessive, may result in blade slided in rotor slot it is dumb.By blade
Graphite material is changed to, the wear-resisting greasy property of graphite is fine, causes neck without worrying that blade is stained with fluid.Use graphite vanes
The generation of reduction problem failure, increase production efficiency.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the front view of the present invention.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
Any feature disclosed in this specification, unless specifically stated otherwise, can be equivalent by other or with similar purpose
Alternative features are replaced.I.e., unless specifically stated otherwise, each feature is an example in a series of equivalent or similar characteristics
.
As shown in Fig. 1 the present invention provides a kind of vane pump for this, its feature exists to solve present problems
In, including blade, vane tip be adjacent on stator inner surface, inlet port is located at vane pump both ends, stator respectively with press oil port
In vane pump center.
Preferably, the blade is graphite material
The beneficial effects of the invention are as follows：
Indivedual blade activities are dumb, as oil viscosity is excessive, may result in blade slided in rotor slot it is dumb.By blade
Graphite material is changed to, the wear-resisting greasy property of graphite is fine, causes neck without worrying that blade is stained with fluid.Use graphite vanes
The generation of reduction problem failure, increase production efficiency.
The invention is not limited in foregoing embodiment.The present invention, which expands to, any in this manual to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
