The blade pump has the advantages of simple structure, convenience in manufacturing, small energy consumption, steady performance and long service life, more important, the blade pump can be applied to the transportation of gas, liquid such as water, and the like.
Description
Technical field
The present invention relates to a kind of vane pump.
Background technique
Vane pump mainly is made up of rotor, stator (being the pump housing), blade and end cap, stator has the internal surface of cylindrical hole, and rotor is the cylindrical body with radial groove, lays blade in the groove, blade can be free to slide in groove, and rotor eccentricity is installed in the cylindrical hole of stator.The vane pump of prior art, general special finger sliding vane pump, its blade all is a sliding vane, and when rotor during by prime mover driven rotary, blade relies on centrifugal force or spring force or root of blade to feed pressure oil and is pressed on the stator inner surface, preceding half way around at rotor, the space that adjacent two blades surrounded increases gradually and forms parital vacuum and suck liquid, half way around then, and this space reduces gradually, the extruding liquid, with feeding liquid under pressure in discharge tube.
In the prior art, the blade of vane pump all is a sliding vane, complex structure, the accuracy of manufacturing height, because the blade of sliding vane will rely on centrifugal force or spring force to be pressed on the stator inner surface, not only there is the possibility of blocking during blade working, and vane top is also easy to wear, so the power consumption of the vane pump of prior art is bigger, performance is unstable, working life is shorter, what is more important in addition, owing to there is bigger friction when vane top and stator inner surface press during work, so vane pump generally can only use at lubricated good oily medium system, as lathe, oil hydraulic press, handling machinery, the hydraulic system of engineering machinery and plastics machinery etc. and lubrication system, and can not be at gas, liquid medium occasions such as water are applied.
Summary of the invention
In view of the problem that present known technology exists, the technical problem to be solved in the present invention be to provide a kind of simple in structure, easily manufactured, power consumption is little, stable performance, long service life, can suitable gas and the vane pump carried of liquid such as water.
For solving the problems of the technologies described above, the present invention takes following technological scheme to finish:
A kind of vane pump, comprise stator, rotor and blade, stator has the internal surface of cylindrical hole, rotor is the cylindrical body with radial groove, rotor eccentricity is installed in the cylindrical hole of stator, blade is free to slide in the radial groove of rotor, it is characterized in that: described vane pump has sharf, sharf and the coaxial installation of the cylindrical hole of stator, described blade is connected on the sharf, each blade forms the impeller with fixed outer diameter, is rotatably assorted between the cylindrical hole internal surface of impeller and described stator.
The invention has the beneficial effects as follows: all blades are connected on the sharf, each blade forms the impeller with fixed outer diameter, be rotatably assorted between the cylindrical hole internal surface of impeller and described stator, so, blade does not need to be pressed on inner surface of stator by the effect of centrifugal force or spring force during vane pump work, there is not friction (leaving the gap that is rotatably assorted between the two) between vane top and the stator inner surface, so just solved the various deficiencies that existing vane pump exists in the background technique, vane pump of the present invention is simple in structure, easily manufactured, it is little to consume energy, stable performance, long service life, can not only be suitable for oily media fluid occasion, can also suitable gas and liquid occasion such as aqueous medium.Thus, the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement.
As preferably, every blade is independently, every blade pivot bush unit on described sharf.
As preferably, all blades are disjunctors, and the blade of disjunctor is pivot bush unit on described sharf, and blade can freely swing.Blade adopts plastic materials, and the root of blade is provided with the collar, and the root of blade narrows and is connected on the collar.The compact structure of above-mentioned blade is skillfully constructed, and it is suitable especially to use in the vane pump of ting model.
As preferably, described rotor one end opening also has hollow structure.

Embodiment
Accompanying drawing has been represented technological scheme of the present invention and embodiment, further describes each relevant details and working principle thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1,2,3,4, this kind vane pump, comprise stator 1, rotor 2, blade 3(blade is five), sharf 5 and end cap 7, stator 1 has the internal surface of cylindrical hole 4, end cap 7 is fixedlyed connected with stator 1 by screw, rotor 2 is the cylindrical bodys with radial groove 9, rotor 2 one end openings also have hollow structure, spindle nose 8 pivoting supports that rotor 2 the other ends are connected with prime mover are on end cap 7, rotor 2 off-centre are installed in the cylindrical hole 4 of stator, blade 3 is free to slide in the radial groove 9 of rotor, the cylindrical hole 4 coaxial installations of described sharf 5 and stator, sharf 5 is fixed on the side cover of stator 1, described blade 3 is connected on the sharf 5, and each blade 3 forms the impeller with fixed outer diameter, is rotatably assorted between cylindrical hole 4 internal surfaces of impeller and described stator, every blade 3 is independently, and every blade 3 is provided with the collar 6 by its root and is actively socketed on the described sharf 5.
With reference to accompanying drawing 5, all blade 3(blades are three) be disjunctor, blade 3 adopts plastic materials, the collar 11 that the blade 3 of disjunctor is provided with jointly by its root is actively socketed on the described sharf 5, the root 10 of blade 3 narrows and is connected on the collar 11, because the rigidity at root of blade 10 positions is little, pliability is good, so blade can freely swing.
Vane pump of the present invention, all blades are connected on the sharf, each blade forms the impeller with fixed outer diameter, be rotatably assorted between the cylindrical hole internal surface of impeller and described stator, so blade can not be pressed on inner surface of stator during vane pump work, leaves the gap that is rotatably assorted between the two, does not have friction between vane top and the stator inner surface, the present invention not only is suitable for oily media fluid occasion, can also suitable gas and liquid occasion such as aqueous medium.
When the present invention works, rotor is by prime mover driven rotary, rotor drives the blade rotation simultaneously, because rotor and impeller shaft exist eccentric, so blade is when rotating, blade can slide in the radial groove of rotor, but the impeller outer diameter that blade forms is constant all the time, all the time be in the state of being rotatably assorted between the cylindrical hole internal surface of impeller and stator, at the preceding half way around of rotor, the space that adjacent two blades surrounded increases the formation parital vacuum gradually and sucks liquid, half way around then, this space reduces gradually, the extruding liquid, with feeding liquid under pressure in discharge tube.
