Abstract
The present invention discloses a kind of novel damping 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, shock relieve vent（6）It is arranged in shell.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.The design of snubber block is added, the vibrations sent in blade pump work can be reduced, the probability of damage is reduced, guarantee safe production.
Description
Technical field
The present invention relates to mechanical field, more particularly, to a kind of novel damping 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 novel damping vane pump for this, it is characterised in that including leaf to solve present problems
Piece, vane tip are 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
Center, shock relieve vent are arranged in shell.
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 design of snubber block is added, can reduce what is sent in blade pump work
Vibrations, reduce the probability of damage, guarantee safe production.
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 kind of a novel damping vane pump, its feature for this to solve present problems
It is, including blade, vane tip are adjacent on stator inner surface, inlet port is located at vane pump both ends respectively with press oil port, fixed
Son is arranged in shell in vane pump center, shock relieve vent.
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 design of snubber block is added, can reduce what is sent in blade pump work
Vibrations, reduce the probability of damage, guarantee safe production.
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.
