Abstract
The present invention relates to an improvement of oil transfer pump structures, which comprises a pump body and an eccentric rotor. The present invention has the structure key point that a blade in a sealing pad of a guide groove of the eccentric rotor is fixed to a bearing outer sleeve; a bearing is fixed to the pump body with the same circle center with the inner wall of the pump body; a gap exists between the extreme end of the blade and the inner wall of the pump body. The present invention has the characteristics of long service life, simple structure, etc.
Description
Technical field:
The present invention relates to the improvement of oil transfer pump structure.
Background technique:
Oil transfer pump normally is made up of the pump housing and eccentric rotor, has radial blade on the eccentric rotor.When eccentric rotor rotated, blade rotated simultaneously thereupon, and blade is done radial motion, with interlobate folded liquid, constantly liquid is exported.But its shortcoming is because centrifugal action slides the blade pump housing inwall that reclines, and therefore easily inwall is scratched, blade is impaired, and then produces vicious circle, cause the pump housing to produce high vibration, so that oil transfer pump can not re-use very soon.
Summary of the invention:
Purpose of the present invention just provides a kind of can the raising working life greatly, oil transfer pump simple in structure.
The object of the present invention is achieved like this: the present invention includes the pump housing, eccentric rotor, its structure outline is that the interior vanes fixed of sealing gasket of the guide groove of eccentric rotor puts at the outer of bearing, bearing fixing with the pump housing of the inwall concentric of the pump housing on, have the gap between the inwall of blade outermost end with the pump housing.
Major advantage of the present invention:
1. long service life:
Because epitrochanterian vanes fixed of the present invention puts at the outer of bearing, and bearing is on the pump housing that is fixed on the inwall concentric of the pump housing, therefore, rotates simultaneously at eccentric rotor, and the blade on it is still done to rotate with the circumference of the inwall concentric of the pump housing; In addition, the outermost end of blade has the gap with the inwall of the pump housing, and does not touch pump housing inwall, does not just scratch inwall, therefore the working life that can improve pump greatly;
2. simple in structure:
The present invention is exactly on the architecture basics of existing oil transfer pump, has only increased bearing structure and blade and has done some transformation, just can reach purpose of the present invention, so its structure is extremely simple, is easy to popularize.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment:
The present invention includes the pump housing 8, eccentric rotor 6, blade 3 in the sealing gasket 13 of the guide groove 4 of eccentric rotor 6 is fixed on the overcoat 9 of bearing 10, bearing 10 is fixed on the pump housing 8 with inwall 5 concentrics of the pump housing 8, has the gap between the inwall 5 of blade 3 outermost end with the pump housing 8.
Narrate course of action of the present invention below:
Axle 1 rotation in the sealing gasket 2 on the eccentric pump cover 11, the blade 3 on the eccentric rotor 6 on the axle 1 is when entry end 12, and entrained liquid rotates to outlet 14 places thereupon between the blade 3, and this pump comes to this and carries liquid again and again.
Claims (3)
1. oil transfer pump, comprise the pump housing (8), eccentric rotor (6), the interior blade (3) of sealing gasket (13) that it is characterized in that the guide groove (4) of eccentric rotor (6) is fixed on the overcoat (9) of bearing (10) with groove (7) form, bearing (10) is fixed on the pump housing (8) with inwall (5) concentric of the pump housing (8), has the gap between the inwall (5) of the same pump housing of blade (3) outermost end (8).
2. a kind of oil transfer pump according to claim 1 is characterized in that blade (3) is that to be symmetrical arranged be six.
3. a kind of oil transfer pump according to claim 1 is characterized in that having 0.05～0.15 mm clearance between the inwall (5) of the same pump housing of blade (3) outermost end (8).
