Abstract
The utility model relates to a vehicular water pump with high sealing performance. The vehicular water pump comprises a shell with an inner cavity. A water pump shaft and bearings are arranged in the inner cavity. An impeller is arranged at one end of the water pump shaft, and the other end of the water pump shaft extends out of the inner cavity. The impeller is linked and matched with the water pump shaft. The water pump shaft is arranged in the inner cavity through the bearings. A water seal is arranged between the water pump shaft on one side of the impeller and the inner cavity, and comprises corrugated pipe seats, elastic corrugated pipes, stationary rings and swiveling rings, wherein the elastic corrugated pipes are arranged on the corrugated pipe seats. The water seal also comprises a shaft sleeve, wherein the shaft sleeve is linked with the water pump shaft and the swiveling rings. A sealing gasket is arranged between each swiveling ring and the shaft sleeve. The stationary rings are pressed against the swiveling rings and the elastic corrugated pipes respectively. By adopting the technical scheme, the vehicular water pump with high sealing performance has a long service life, and a medium leakage phenomenon can be well prevented.
Description
Technical field
The utility model relates to the pump class, particularly a kind of high leak tightness vehicle water pump.
Background technique
At present, existing a kind of vehicle water pump includes the housing that is provided with inner chamber; In inner chamber, be provided with water pump spindle, bearing, water pump spindle one end is provided with impeller, and the other end extends to outside the inner chamber and is connected with control gear; Impeller and water pump spindle are linked, and this control gear is used for driving the water pump spindle rotation, thus the impeller rotation; Water pump spindle is provided with water seal between the water pump spindle of impeller one side and inner chamber in bearing is arranged on inner chamber, water seal is used for anti-sealing and gets into the proper functioning that influences water pump spindle in the inner chamber.Wherein, water seal includes corrugated header, elastic bellows, stationary ring and rotating ring, and elastic bellows is arranged on the corrugated header, rotating ring and water pump spindle interlock, and after impeller assembles, the inconsistent realization sealing function of rotating ring and stationary ring.
But the vehicle water pump of this structure is when water pump assembles; Because stationary ring, rotating ring branch are arranged, and usually have fine particle and are bonded at the surface, during assembling; Be difficult to clean out, and water seal do not use under the regulation working depth, be easy to generate the medium leakage phenomenon after the assembling; Life of product reduces, and causes unnecessary trouble.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of vehicle water pump, can prevent the generation of medium leakage phenomenon well, long service life.
The technological scheme of the utility model: a kind of high leak tightness vehicle water pump, include the housing that is provided with inner chamber, in inner chamber, be provided with water pump spindle, bearing; Water pump spindle one end is provided with impeller, and the other end extends to outside the inner chamber, and impeller and water pump spindle are linked; Water pump spindle is in bearing is arranged on inner chamber; Between the water pump spindle of impeller one side and inner chamber, be provided with water seal, described water seal includes corrugated header, elastic bellows, stationary ring, rotating ring, and described elastic bellows is arranged on the corrugated header; Water seal also includes the axle sleeve with the water pump spindle interlock; Described rotating ring and axle sleeve interlock are provided with seal ring between described rotating ring and the axle sleeve, and described stationary ring is conflicted with rotating ring, elastic bellows respectively.
Adopt technique scheme, the water seal setting of this structure, owing to be provided with seal ring between rotating ring and the axle sleeve, stationary ring is conflicted with rotating ring, elastic bellows respectively, can prevent the generation of medium leakage phenomenon well.
The further setting of the utility model: described elastic bellows sidewall is provided with annular groove, is axially arranged with pressure spring along axle sleeve in the described annular groove, conflicts with the two side of annular groove respectively in described pressure spring two ends.
Adopt above-mentioned further setting, can further improve the sealability of water seal, thereby prevent the generation of medium leakage phenomenon better so that stationary ring and rotating ring conflict are tightr through the pressure spring that is provided with, and long service life.
