Abstract
The utility model discloses an integrated water seal automobile water pump which comprises a pump body, an impeller shaft and a water seal. The water seal comprises a sealing seat, a bellow, a spring, a fixed ring and a movable ring, wherein the sealing seat is pressed and fixed in an inner hole of the pump body, the bellow is arranged in the sealing seat, the spring is positioned in a bellow groove of the bellow to elastically support the bellow, the fixed ring is attached to an outer end face of the bellow, and the fixed ring and the movable ring are oppositely arranged. The integrated water seal automobile water pump is characterized in that the movable ring is connected with a sleeve, and the sleeve is pressed and fixed on the impeller shaft. The integrated water seal automobile water pump is of an integrated water seal structure, the working height of the integrated water seal is directly guaranteed by a pressing clamp in pressing installation, and the integrated water seal automobile water pump is stable, reliable, good in sealing performance and free of maintenance in a using process.
Description
Technical field
The utility model relates to a kind of auto parts and components, is specifically related to a kind of improvement invention of automobile engine cooling water pump.
Background technique
At present; The sealing means that automobile engine cooling water pump generally adopts is mechanical seal; Mechanical seal is meant by at least one pair of end face perpendicular to spin axis; Under the effect of hydrodynamic pressure and compensation mechanism elastic force, and the cooperation of auxiliary seal keeps down fitting and slide relative and the device that prevents escape of liquid that constitutes.And split type water seal is modal a kind of mechanical sealing element.Its principle is to press-fit cooperation, make mating face seal by elastic force.A split type water seal part is a stationary ring; Another part is a rotating ring, because rotating ring is to be fixed on the impeller, so split type water seal its working depth when assembling need rely on press-fiting highly indirectly of impeller to guarantee; The poor dimensional stability of working depth; Because dynamic and static ring separates before the impeller assembling, and its matching trim has impurity or other granule to get into easily, produce dynamic and static ring sealing surface and scratch and cause the water seal leakage again.
Summary of the invention
To the deficiency of existing technology, the utility model provides a kind of employing integrated type sealing structure for water, and working depth is reliable and stable, good seal performance, non-maintaining auto pump in the using process.
The utility model takes following technological scheme to accomplish:
Integrated type water seal auto pump comprises the pump housing, impeller shaft and water seal, and water seal comprises sealing seat, bellows, spring, stationary ring and rotating ring; Sealing seat press-fits fixing at pump housing endoporus, bellows is provided with in sealing seat, and the interior elasticity of wave groove that spring is located at bellows struts bellows; Stationary ring abuts in the exterior edge face of bellows; Stationary ring and rotating ring are oppositely arranged, and it is characterized in that: rotating ring is connected with sleeve, and sleeve press-fits fixing on impeller shaft.
Above-mentioned auto pump has adopted the integrated type sealing structure for water, as its name suggests; The integrated type water seal water seal that promptly integral installation is accomplished before the assembling impeller; Because it is fixing that the sealing seat of water seal press-fits at pump housing endoporus, sleeve press-fits fixing on impeller shaft, so the working depth of integrated type water seal can directly be guaranteed by pressing clamp when press-fiting; Working depth is reliable and stable, non-maintaining in the using process (split type water seal adds matter lubricant oil clearly at dynamic and static ring sealing surface); Also have, dynamic and static ring owing to the fit-state that act as of spring force, has been avoided foreign matter or other impurity to get into sealed working face and has been produced the phenomenon that scratches, good seal performance under free state.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the partial structurtes view of integrated type water seal auto pump;
Fig. 2 is the structure enlarged view of water seal parts among Fig. 1.
Embodiment
Describe the embodiment of the utility model in detail below in conjunction with accompanying drawing.
As shown in the figure, the integrated type water seal auto pump of the utility model comprises the pump housing 1, impeller 4, impeller shaft 3 and integrated type water seal 2; Integrated type water seal 2 is made up of sealing seat 5, bellows 7, spring 8, spring seat 6, stationary ring 9, rotating ring 10, rotating ring pad 11 and sleeve 12, and sealing seat 5 press-fits fixing at the pump housing 1 endoporus, and bellows 7 is provided with in sealing seat 5; The interior elasticity of wave groove that spring 8 is located at bellows 7 struts bellows 7, and the two ends of spring 8 are provided with said spring seat 6, and stationary ring 9 abuts in the exterior edge face of bellows 7; Stationary ring 9 is oppositely arranged with rotating ring 10; Rotating ring 10 is located in the sleeve 12, and its bottom is lined with said rotating ring pad 11, and sleeve 12 press-fits fixing on impeller shaft 3.
The integrated type water seal auto pump of the utility model; Because the sealing seat 5 of water seal press-fits fixing at the pump housing 1 endoporus; Sleeve 12 press-fits fixing on impeller shaft 3; So the working depth H of integrated type water seal can directly be guaranteed that when press-fiting working depth H is reliable and stable by pressing clamp, non-maintaining in the using process (split type water seal adds matter lubricant oil clearly at dynamic and static ring sealing surface); Also have, dynamic and static ring owing to the fit-state that act as of spring force, has been avoided foreign matter or other impurity to get into sealed working face and has been produced the phenomenon that scratches, good seal performance under free state.
