Abstract
The utility model relates to a vehicular water pump with flanges. The vehicular water pump comprises a pump casing in which an inner cavity is formed. A rotating shaft is arranged in the inner cavity. An impeller is arranged at one end of the rotating shaft, and a hub is arranged at the other end of the rotating shaft. The rotating shaft is arranged in the inner cavity through bearings. A water seal is arranged between the rotating shaft and the inner wall of the inner cavity, and is positioned between the impeller and the bearings. The vehicular water pump also comprises the flanges each of which is made of aluminum alloy. The flanges are fixedly connected with the pump casing. An oil seal is arranged between each flange and the hub. By adopting the technical scheme, the vehicular water pump with the flanges is low in cost and energy consumption, and high in accuracy.
Description
Technical field
The utility model relates to the pump class, particularly a kind of vehicle water pump that has flange plate.
Background technique
At present, existing a kind of vehicle water pump includes pump case; Be provided with inner chamber in the pump case, be provided with running shaft in the inner chamber, rotating shaft terminal is respectively equipped with impeller, wheel hub; Running shaft is provided with water seal between running shaft and the interior cavity wall in bearing is arranged on inner chamber, water seal is between impeller and bearing.
But there is big gap in the vehicle water pump of this structure between wheel hub and the interior cavity wall, and some impurity can get into inner chamber by the gap, influence bearing, thereby make that the precision of water pump is low.
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 that has flange plate, and cost is low, energy consumption is little and precision is high.
The technological scheme of the utility model: a kind of vehicle water pump that has flange plate, include pump case, be provided with inner chamber in the pump case; Be provided with running shaft in the inner chamber, rotating shaft terminal is respectively equipped with impeller, wheel hub, and running shaft is in bearing is arranged on inner chamber; Be provided with water seal between running shaft and the interior cavity wall, water seal also includes the flange plate that aluminum alloy is processed between impeller and bearing; Described flange plate is fixedly connected with pump case, is provided with oil sealing A between described flange plate and the wheel hub.
Adopt technique scheme, through flange plate is set, and between flange plate and wheel hub, oil sealing A is set, can prevent that medium from getting into inner chamber between wheel hub and inner chamber, and then can make that the precision of water pump is high; Described flange plate is that aluminum alloy is processed, and can reduce cost, and reduces energy consumption.
The further setting of the utility model: described pump case includes the pump housing, cover plate, and the described pump housing, cover plate connect through screw.
Adopt above-mentioned further setting, through described pump case split is provided with, can be so that the installation of impeller, running shaft, bearing, water seal in the pump case, dismounting be convenient, thus reduced cost of production.
Further being provided with again of the utility model: be provided with oil sealing B between described bearing and the water seal.
Adopt above-mentioned further setting again, oil sealing B is set between bearing and water seal, can prevent that medium from getting in the inner chamber, influences bearing, and then influence the service behaviour of water pump.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
