Abstract
The invention relates to a spray pump device of an automobile. The spray pump device comprises a driving device and a spray pump connected with the driving device, wherein the spray pump comprises a pump body, a pump shaft arranged in the pump body, and an impeller arranged at the front end of the pump shaft; the inner wall of the pump body is provided with a sealing element at a position corresponding to the hub of the impeller; a bearing sleeve is arranged between the pump shaft and the open end of the pump body. A sealing ring arranged between the pump body and the impeller of the spray pump device is convenient to disassemble and assemble after being damaged and is convenient to maintain, and the pump body does not need to be replaced; the bearing sleeve is arranged between the pump shaft and the open end of the pump body, thereby reducing the friction resistance between the rotating pump shaft and the open end of the pump body and increasing the working efficiency of the spray pump.
Description
Technical field
The present invention relates to a kind of drive unit of automobile, especially a kind of in water the spray pump-unit of running automobile.
Background technique
In known technology, the electric jet pump of motor car engine is the pump core of being made by powder metallurgical body and the pump housing matching with this pump core, pump core is under the drive of motor, by the driving mechanism High Rotation Speed in the eccentric circumference of pump housing outer ring of self, by the pump housing, spray water backward, thereby promoting vehicle capable of travelling on water moves forward, on market, the pump core of existing spray pump is made by pump shaft and the impeller that is arranged on pump shaft front end, be provided with seal ring with the inwall of the corresponding pump housing of impeller hub, seal ring and pump housing integrally casting, during work, impurity in liquid and impeller and the mutual friction of seal ring phase, wearing and tearing seal ring, the gap of seal ring and impeller is increasing, the efficiency of pump declines gradually, use after a period of time, need to change seal ring, because seal ring and the pump housing are integrated casting, can only change the whole pump housing, the working life of the pump housing is short, maintenance cost is high, and the pump shaft of existing spray pump when rotated, linkage between pump shaft and the opening end of the pump housing is bad, cause pump shaft when rotated, resistance is larger, efficiency is lower.
Summary of the invention
To the object of the invention is to spray the existing defect of pump in order solving in prior art, a kind of long service life to be provided, simple in structure, be convenient to the spray pump-unit of automobile of maintenance.
To achieve these goals, the technical solution used in the present invention is:
A kind of spray pump-unit of automobile, comprise drive unit and the spray pump being connected with this drive unit, described spray pump comprises the impeller that the pump housing is arranged on the pump shaft in the pump housing and is arranged on pump shaft front end, on the inwall of the described pump housing, be provided with Sealing with the wheel hub corresponding section of described impeller, between described pump shaft and the opening end of the pump housing, be provided with bearing housing.
The spray pump-unit of above-mentioned a kind of automobile, described Sealing is seal ring, sealing ring is arranged on the described pump housing by the mode of interference fit.
The spray pump-unit of above-mentioned a kind of automobile, described drive unit is motor.
The spray pump-unit of above-mentioned a kind of automobile, described pump shaft is connected by line belt with the output shaft of drive unit.
The spray pump-unit of above-mentioned a kind of automobile, described seal ring and the described pump housing are split part.
Beneficial effect of the present invention is: the seal ring being provided with between the pump housing of this spray pump-unit and impeller is convenient to dismounting after impaired, easy to maintenance, do not need to change the pump housing, the bearing housing being provided with between pump shaft and the opening end of the pump housing, reduce the surface friction drag of pump shaft when rotated and between pump housing opening end, strengthened the working efficiency of spray pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Fig. 2 is the side view that pump-unit spray pump is sprayed in the present invention
Fig. 3 is the sectional view that pump-unit spray pump is sprayed in the present invention
Fig. 4 is the structural representation that pump-unit impeller is sprayed in the present invention
Embodiment
For making that structure characteristic of the present invention and the effect reached are had and further understand and be familiar with, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figures 1 to 4, a kind of spray pump-unit of automobile, comprise drive unit 1 and the spray pump 2 being connected with this drive unit 1, spray pump 2 comprises the impeller 5 that the pump housing 3 is arranged on the pump shaft 4 in the pump housing 3 and is arranged on pump shaft 4 front ends, on the inwall of the pump housing 3, be provided with Sealing 6 with the wheel hub corresponding section of impeller 5, between pump shaft 4 and the opening end of the pump housing 3, be provided with bearing housing 7.
In the present invention, Sealing 6 is preferably seal ring, and drive unit 1 is preferably motor, and sealing ring is arranged on the pump housing 3 by the mode of interference fit.
After drive unit 1 starts, the output shaft of drive unit drives pump shaft 4 rotations by line belt 8, pump shaft 4 impeller 5 High Rotation Speeds, blade in impeller 5 forces liquid in rotation, liquid is done work, its momentum is increased, liquid is under the effect of centrifugal force, to impeller surrounding, throw away, by the whirlpool type pump housing 3, convert kinetic energy to pressure energy, after the liquid in impeller 5 is discharged, the pressure in impeller 5 is lower than the pressure in the pump housing 3 opening ends, new liquid is inhaled into impeller 5 under the effect of pressure difference, and liquid just continuously discharges from the pump housing 3.
Particularly for amphibious vehicle, can pass through engine operation under water time, available spray pump-unit promotes water body, reach the effect that car body is advanced, in water, speed per hour can reach tens kilometers/hour, mainly while working under water, can work together with motor simultaneously, also can the work of drive car body.
During underwater operation, play the effect of auxiliary drive, meanwhile, can be in the situation that motor cannot be worked, continue to make car body work to advance, become the second power that car body advances, the seal ring being provided with between the pump housing 3 of this spray pump-unit and impeller 5 is convenient to dismounting after impaired, easy to maintenance, do not need to change the pump housing, the bearing housing 7 being provided with between the opening end of pump shaft 4 and the pump housing 3, has reduced the surface friction drag of pump shaft 4 when rotated and between the pump housing 3 opening ends, has strengthened the working efficiency of spray pump.
More than show and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain that the present invention requires is defined by appending claims and equivalent thereof.
