Abstract
The invention relates to a cooling water pump for the automobile motor. The cooling water pump comprises a water pump casing body combined with an engine cylinder body, a sealing cavity is formed by the water pump casing body and the cylinder body combined, a water pump impeller driven by a water pump wheel shaft and a water inlet opening is arranged at the position of the sealing cavity, the water inlet opening is arranged on the engine cylinder body, and two water outlet openings are respectively arranged at the two sides of the water pump casing body. A pressure relief hole is added in the blade inlet opening of the water pump impeller. The water pump drive adopts double-row sprocket drive. The water pump is provided with two water outlet openings, thus the flow quantity of the water pump is increased; the water pump impeller adopts a plastic structure, thus, on one hand, the whole mass of the water pump is lightened, and the rotational inertia is reduced; on the other hand, the water pump efficiency is enhanced; and the pressure relief hole is added in the blade inlet opening of the water pump impeller, thus the front and rear water pressure of the impeller is balanced, the cavitation erosion surplus is reduced, and the pressure relief hole can also play a cooling and water sealing role. The water pump drive adopts the double-row sprocket drive, thus, on one hand, the work efficiency of the water pump is enhanced, and on the other hand, the work stability of the water pump is strengthened.
Description
Technical field
The present invention relates to a kind of water pump, particularly relate to a kind of automobile engine cooling water pump.
Background technique
At present, the water intake of motor car engine water pump mostly on water pump cover, single formula water outlet; Water pump vane adopts metallic impeller more, and the cavitation erosion problem is more; Water pump drives the belt drives that adopt more, and driving force is single, and causes the belt slippage phenomenon easily; Water pump abnormal sound problem is also more.Chinese patent application numbers 200410059751.7 discloses a kind of water pump that is used for internal-combustion engine, and it comprises: a pump case, and it is suitable for being fixed on the motor; One pump housing, it is engaged on the pump case, thereby forms the fluid chamber of water pump between the pump housing and pump case; And a rotary pump shaft component, it extends through the pump housing and extend in the fluid chamber.One is used for the fastening kit that pump case is fastened to the pump housing is comprised fastening piece or the bolt that is positioned at pump case one side, and its direction along the rotation pump shaft is extended to the pump housing one side from pump case one side.There is above-mentioned deficiency equally in it.
Summary of the invention
The objective of the invention is to the deficiency that exists in the existing automobile engine cooling water pump, a kind of automobile engine cooling water pump is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automobile engine cooling water pump, comprise the water pump cover that combines with engine cylinder-body, water pump cover combines with cylinder body and forms sealing an actor's rendering of an operatic tune, there is water pump to take turns shaft-driven water pump vane and water intake at sealing an actor's rendering of an operatic tune position, water intake is arranged on the engine cylinder-body, it is characterized in that, arrange two water outlets in the water pump cover both sides respectively.
In order further to improve the efficient of water pump, the hydraulic pressure before and after the balanced impeller has reduced net positive suction head, plays the effect of cooling water seal; Inlet is provided with relief hole at the water pump vane blade.
In order further to have alleviated the water pump total quality, reduced rotary inertia, water pump vane adopts plastic material structure.
In order further to have improved the working efficiency of water pump, the working stability of water pump is strengthened, water pump drives and adopts the duplex chain wheel transmission.Be that the water pump wheel shaft the other end connects duplex chain wheel.
Good effect of the present invention is:
1, pump intake is arranged on the engine cylinder-body body, makes little, the compact structure of water pump arrangement space, and has two water outlets, the flow of the water pump of increase.
2, water pump vane adopts plastic construction, has alleviated the water pump total quality on the one hand, has reduced rotary inertia; Improved the efficient of water pump on the other hand; And increased pressure relief vent on the water pump vane, balanced hydraulic pressure before and after the impeller has reduced net positive suction head, but also can play the effect of cooling water seal.
3, water pump drives and adopts the duplex chain wheel transmission, has improved the working efficiency of water pump on the one hand, and the working stability of water pump is strengthened.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
