Abstract
The utility model discloses a kind of blade pump piston, it mainly include ontology, horn mouth, macropore and aperture, ontology is cylindrical, the whole body of ontology offers several annular recess, horn mouth, macropore and aperture are provided with body central position, and horn mouth, macropore and aperture three are coaxial, the utility model designs a kind of piston for vane pump, horn mouth on the piston, the size of macropore and aperture can be adjusted, for controlling the oil mass of vane pump disengaging, vane pump adverse effect as caused by oil suction can effectively be improved, and the dirt in oil can be discharged in the annular recess opened up on the whole body of piston, improve the reliability of work.
Description
Technical field
The utility model relates to vane pump field more particularly to a kind of blade pump pistons.
Background technique
Vane pump is widely used in many fields, and wherein vane pump is as one kind more conventional in vane pump,
The stator inner surface of vane pump is a circle, there is eccentricity between rotor and stator, and an oil suction window is only provided on oil distribution casing
Mouth and a pressure oil window.When rotor rotates under motor drive, when vanes stator lower half, in the effect of centrifugal force
Under, it is stretched out from blade groove, two interlobate sealed volumes increase, and realize oil suction；When the vanes stator upper half, by stator
Surface is gradually pressed into blade groove, and sealed volume is reduced, and realizes pressure oil.The rotor every revolution of pump, each sealed volume are inhaled, are pressed
Oil is each primary.Change the eccentricity between stator and rotor, the discharge capacity of pump can be changed, in order to make vane pump reliably oil suction,
Revolving speed must be in the range of 500~1500r/min, when revolving speed is too low, and blade cannot press inner surface and the oil suction of stator；Revolving speed
It is too high, " being emptied " phenomenon of pump is caused, the work of pump is abnormal.The viscosity of oil will be selected suitably, and viscosity is too big, oil suction resistance
Increase；Oil liquid is excessively dilute, and gap influences, and vacuum degree is inadequate, adverse effect can be caused to oil suction, therefore how to require according to specific
Become particularly important to change the discharge of vane pump, and vane pump is very sensitive to the dirt in oil, functional reliability is poor, oil liquid
It is unclear that blade can be made stuck.
Utility model content
Based on the above, the utility model provides a kind of blade pump piston, non-adjustable to solve existing vane pump oil mass
And the intractable problem of dirt in oil.
For this purpose, the utility model uses following technical scheme:
A kind of blade pump piston, including ontology, horn mouth, macropore and aperture, the ontology is cylindrical, the whole body of ontology
Several annular recess are offered, the horn mouth, macropore and aperture are provided with body central position, and horn mouth, macropore
Three is coaxial with aperture.
As a kind of preferred embodiment of the utility model, the bell-mouthed outside is provided with scarf.
As a kind of preferred embodiment of the utility model, the side of vane pump is arranged in the ontology, described bell-mouthed
The central axis of central axis and vane pump is mutually perpendicular to and horn mouth protrudes into vane pump.
The utility model has the following beneficial effects:
The utility model designs a kind of piston for vane pump, the size of horn mouth, macropore and aperture on the piston
It can be adjusted, for controlling the oil mass of vane pump disengaging, it is bad as caused by oil suction can effectively to improve vane pump
It influences, and the dirt in oil can be discharged in the annular recess opened up on the whole body of piston, improve the reliability of work.
Detailed description of the invention
It, below will be to the utility model embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing needed in description is briefly described.
Fig. 1 is the blade pump piston schematic diagram that the utility model embodiment provides；
Fig. 2 be the blade pump piston that provides of the utility model embodiment along A-A to diagrammatic cross-section；
Fig. 3 is the connection schematic diagram of the vane pump that the utility model embodiment provides and piston.
Specific embodiment
The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer,
It is described in further detail below in conjunction with technical solution of the attached drawing to the utility model embodiment.
As shown in Figure 1-Figure 3, present embodiment provides a kind of blade pump piston, including ontology 1, horn mouth 2,3 and of macropore
Aperture 4, institute's ontology 1 is cylindrical, and the whole body of ontology 1 offers several annular recess 5, and horn mouth 2, macropore 3 and aperture 4 are equal
It is provided with 1 centre of ontology, and horn mouth 2, macropore 3 and 4 three of aperture are coaxial, it is preferred that present embodiment is in horn mouth 2
Front position at be provided with scarf 6, the angle of scarf 6 is adjustable, pass through adjust scarf 6 angle and horn mouth
2 diameter controls the input of oil mass.The side of vane pump 7, the center of horn mouth 2 is arranged in ontology 1 in present embodiment
The central axis of axis and vane pump 7 is mutually perpendicular to, and horn mouth 2 protrudes into the inside of vane pump 7 for controlling oil mass.
Note that above are only the preferred embodiment and institute's application technology principle of the utility model.Those skilled in the art's meeting
Understand, the utility model is not limited to specific embodiment described here, is able to carry out for a person skilled in the art various bright
Aobvious variation, readjustment and substitution is without departing from the protection scope of the utility model.Therefore, although passing through above embodiments
The utility model is described in further detail, but the utility model is not limited only to above embodiments, is not departing from
It can also include more other equivalent embodiments in the case that the utility model is conceived, and the scope of the utility model is by appended
Scope of the claims determine.
