Abstract
The utility model discloses a sealing mechanism of a vane pump. Key points of the technical scheme are that: the sealing mechanism of the vane pump comprises a pump body, a vane, a rotor, a stepped rotor shaft and a sealing component, wherein the rotor shaft is provided with a front bearing and a back bearing; the other faces of the sealing component and the front bearing opposite to the back bearing are jointed with each other; and the sealing component comprises a movable ring, a static ring, a gasket and a retainer ring which are connected in sequence. The utility model aims to provide a vane pump sealing mechanism with higher sealing performance.
Description
Technical field
The utility model relates to a kind of sealing mechanism, and more particularly, it relates to a kind of sealing mechanism of vane pump.
Background technique
At present, the sealing mechanism of vane pump comprises the pump housing, blade, rotor and is step-like rotor shaft, and rotor shaft is provided with fore bearing and consequence bearing, and Sealing is located at the step place of rotor shaft.Though this sealing mechanism has played the effect of sealing, DeGrain, impurity will influence the work of machine if drop on the gap between bearing and the Sealing.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of vane pump sealing mechanism of better tightness.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of sealing mechanism of vane pump; Comprise the pump housing, blade, rotor and be step-like rotor shaft and black box; Rotor shaft is provided with fore bearing and consequence bearing, it is characterized in that: said black box is close to setting mutually with the another side of the relative rear bearing of fore bearing.
The utility model further is set to: described black box comprises rotating ring, stationary ring, pad and back-up ring, connects successively between rotating ring, stationary ring, pad and the back-up ring.Through adopting technique scheme, further enhanced leaktightness property.
