For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and attached drawing further
Explanation, the content that embodiment refers to not is restriction to the utility model.
Just as described in the background art, at the low rotational speed, the centrifugal force of rotor blade is inadequate, thus vane tip cannot be very
Good and stator（Or pump case）Between keep good contact so that vane pump shape between its blade and stator under relatively low rotating speed
Into accommodating chamber sealing effect it is bad, cause its volumetric efficiency low, and then reduce the pumping efficiency of vane pump, to solve
This problem, the utility model on the blade of stator and rotor by using magnetic material so that between blade and stator all the time
Since magnetic effect keeps close and good contact, the sealing performance under its slow-speed of revolution is greatly promoted.
A kind of vane pump for improving pumping efficiency under the slow-speed of revolution as shown in figures 1 to 6, including pump case 1, pump cover 2, shaft
3rd, the stator 4 being fixedly mounted on 1 bottom-working surface of pump case and the rotor 5 being fixedly mounted in shaft 3,1 bottom of pump case
For working face, sealing is kept between the working face and stator 4, the working face is equipped with inlet port 6, and the pump cover is equipped with row
Hydraulic fluid port 7, the rotor 5 are equipped with some slots 8 for being used to insert blade, are equipped with and can be radially slided along rotor 5 in the slot 8
Blade 9, it is characterised in that：The blade 9 and stator are formed by ferrimagnet.
In general, there is certain travelling gap between the blade 9 and slot 8 of vane pump, which enables blade
Flexibly moved along the radial direction of rotor 5 in slot 8, connect so as to fulfill inner peripheral surface when rotating all the time with 4 inner cavity of stator
Tactile effect, analysis understand that on the one hand the movement of radial direction occurs when being rotated with rotor 5 with the slot 8 on rotor 5 for blade 9, separately
On the one hand can also impact be produced to the side of slot 8（Particularly when the rotating speed of rotor 5 changes）, this impact makees for a long time
Become larger with the opened gap for be easy to causeing slot 8, reduce the sealing effect between blade 9 and slot 8.
Therefore, further, as shown in figure 3,8 opening of slot of the utility model people on the rotor outer periphery face is equipped with
Strengthening portion 10.The as needed by strengthening portion 10 of obstacle can be had no based on foregoing analysis as those skilled in the art
According to needing to set, for example, it is as shown in Figure 3, the section of strengthening portion 10 is arranged to triangle.
Vane pump work when often with a degree of vibrations, main reasons is that mistake of the vane pump in pump oil
The volume of accommodating chamber in journey between its blade 9 and stator 4 is undergone mutation（When mainly blade 9 runs to oil discharge outlet 7）,
Moment draining effect causes to shake, and to mitigate this vibrations, utility model people has found by multiple CFD analog studies, mitigates
The frequency of mutation of volume and the process of discharge is tended towards stability, the shock-effect of vane pump can be significantly reduced.
Therefore, further, as described in Figure 2, on the basis of aforementioned base technical solution, the pump case 1 of the utility model
7 side of oil discharge outlet of bottom can also open up pre- drain pan 11, and the pre- drain pan 11 is triangle.It should be noted that

Closely contacted in addition, the shape for opening up position and oil discharge outlet 7 of the pre- drain pan 11 and the steering of rotor 5 exist, such as such as
Fruit rotor 5 is to rotate counterclockwise, then pre- drain pan 11 should just be opened in the right side of oil discharge outlet 7, if rotor 5 is to revolve clockwise
Turn, then pre- drain pan 11 just needs to be opened in the left side of oil discharge outlet 7, if especially it is also to be noted that the shape of oil discharge outlet
Irregularly, then pre- drain pan 11 should not only meet foregoing requirement, it is also necessary to be opened in rotor rotate when any blade all
At the contour line first touched（Because oil extraction can be started at this profile at first）.
In general, the flow of vane pump linearly changes with rotating speed, but in actual application, the utility model people
It was found that when rotating speed improve to a certain extent after, the increase trend comparison of flow is gentle, at the same the pump housing of vane pump start occur compared with
For serious vibrations, analyzed by CFD, the improvement of various structures of utility model human simulation, finally draws the side wall in stator 4
On open up increase inlet port 6 oil absorption oil-sucking hole 12, to a certain extent（Under specified flow）It can add
The pump-conveying property of pump（Mainly improve the pump discharge pumped under high rotating speed）.

Some oil-sucking holes 12 are opened up on son）Although pump oil flow under the high rotating speed of vane pump is with larger lifting, still not
Preferable requirement can be reached（I.e. flow still cannot be uniformly linearly increasing with rotating speed）, one skilled in the art will appreciate that to the greatest extent may be used
Vane pump can be increased often rotate the oil suction efficiency of one week and be beneficial to improve the pumping efficiency of vane pump, and influence the pump of vane pump
Send the factor of efficiency many, and the influence proportion with each factor under high rotating speed is also not quite similar at the low rotational speed, therefore
How vane pump at high speed pumping efficiency is effectively further improved, while again without damaging the pumping efficiency under the slow-speed of revolution
Seem particularly difficult, if utility model people is had found in vane pump at high speed by test of many times and combination CFD simulation tests
The receiving efficiency of the accommodating chamber formed between its blade 9 and stator 4 decreases, under extreme rotating speed, in the accommodating chamber very
To there is cavitation phenomena, one skilled in the art that the suction of vane pump is originally the principle that make use of vacuum self-priming, because
This accommodating chamber, which accommodates efficiency and reduces apparently due to rotating speed is too fast, causes accommodating chamber to fail to be filled enough oil, so it is practical
New people sets oil-feed tank 13 on 6 side of inlet port, 1 working face of pump case close to rotor outer periphery face, and the oil-feed tank 13 is main
