Abstract
The utility model discloses an automobile water pump with separation protective devices. The automobile water pump comprises a pump body with an impeller cavity, wherein an impeller is arranged in the impeller cavity, and a linked impeller shaft is fixedly arranged on the impeller. A liquid inlet and a liquid outlet are arranged on the impeller cavity, and the separation protective devices are arranged at the positions of the liquid inlet and the liquid outlet and are used for separating the interior space and the exterior space of the impeller cavity. The automobile water pump has the advantages that the liquid inlet and the liquid outlet are separated in a sealing mode through the separation protective devices so that separation of the interior space and the exterior space of the impeller cavity is ensured and the interior of the automobile water pump is prevented from being invaded by impurities in the transportation process. The separation protective devices are simple in structure, convenient to use and good in sealing effect.
Description
Technical field
The utility model relates to a kind of auto pump, especially a kind of auto pump with isolating and protecting device.
Background technique
At present, auto pump is indispensable important component part on the automobile, and existing auto pump generally is made up of water pump body, axle, belt pulley and impeller etc.Auto pump is a kind of product that Environmental Conditions is had relatively high expectations; therefore; if in the way that auto pump dispatches from the factory, transports and installs; impurity such as external dust enter in the cavity of the interior impeller place of auto pump; these impurity particles can make at auto pump; wearing and tearing are caused in auto pump water pump inside, thereby influence its working life, cause the leakage of internal coolant.For fear of the generation of this situation, before then installing, need once clear up auto pump inside, still, so not only increase working strength of workers, and differ and guarantee that surely the cleaning to inside reaches very.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple and reasonable that the utility model provides, and can prevent the auto pump of the band isolating and protecting device that impurity such as dust is invaded.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of auto pump with isolating and protecting device; comprise the pump housing that has impeller cavity; in this impeller cavity impeller is installed; be installed with the impeller shaft of interlock on the impeller; this impeller cavity is provided with liquid entering hole and liquid outlet; described isolating and protecting device is seal-installed on liquid entering hole and liquid outlet place, and is used for isolating the interior or exterior space of impeller cavity.
In the utility model, isolating and protecting device is seal-installed on liquid entering hole and liquid outlet place, thereby liquid entering hole and the liquid outlet of inside and outside conducting on the impeller cavity is closed, and prevents that thus impurity such as external dust from entering in the impeller cavity.
Further arrange: the liquid inlet pipe with the impeller cavity conducting is extended at described liquid entering hole place, and the drain pipe with the impeller cavity conducting is extended at the liquid outlet place, and described isolating and protecting device is protecting cover, and this protecting cover is sheathed on the opening of liquid inlet pipe and drain pipe respectively.
Adopt technique scheme, this isolating and protecting device is protecting cover, also namely adopts the cover substructure, seals from the outside of liquid inlet pipe and drain pipe opening, thereby realizes the isolation of impeller cavity inside and outside, and cover is simple in structure, and is easy for installation.
Further arrange: described isolating and protecting device is protective plug, and this protective plug is inserted in the opening of liquid inlet pipe and drain pipe respectively.
Adopt technique scheme, this isolating and protecting device is protective plug, also namely adopts the structure of stopper, seals from the inside of liquid inlet pipe and drain pipe, thereby realizes the isolation of impeller cavity inside and outside, and plug structure is simple, and is easy for installation.
Further arrange: have main liquid entering hole and time liquid entering hole on the described liquid inlet pipe, the diameter of inferior liquid entering hole is less than the diameter of main liquid entering hole.
Further arrange: described liquid entering hole diameter is 0.2 ~ 0.5 times of main liquid entering hole diameter again.
Adopt technique scheme, as required, liquid inlet pipe is provided with two liquid entering holes, is respectively main liquid entering hole and time liquid entering hole, and this time liquid entering hole diameter is 0.2 ~ 0.5 times of main liquid entering hole diameter, is preferably 0.4 times.
Further arrange: described impeller shaft partly extends to the outer and formation driving section of the pump housing, is arranged with belt wheel on this driving section.
Adopt technique scheme, because the belt wheel transmission stability is good, the transmission efficiency height is so the driving section on impeller shaft is provided with the belt wheel for the belt wheel transmission.
The beneficial effects of the utility model are: by isolating and protecting device, thereby liquid entering hole and liquid outlet are carried out seal isolation, guarantee the isolation in space, impeller cavity inside and outside thus, thereby avoid auto pump inside to be subjected to the intrusion of impurity in transportation process.This isolating and protecting device is simple in structure, and is easy to use, and has good sealing effect.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, 2, present embodiment comprises the pump housing 1 that has impeller cavity 11, in this impeller cavity 11 impeller 2 is installed, and is equipped with the impeller shaft of fixing with impeller 23 on the impeller 2, and the joint of impeller shaft 3 and impeller cavity 11 is provided with water seal part 4.Impeller shaft 3 parts extend to the pump housing 1 outer and formation driving section, are arranged with belt wheel 5 on this driving section, cooperate with belt when belt wheel 5 is used for being with transmission.Be provided with liquid entering hole and liquid outlet at this impeller cavity 11, on liquid entering hole and liquid outlet, extend the liquid inlet pipe 12 and the drain pipe 13 that are conducted with impeller cavity 11 respectively, and the opening away from impeller cavity 11 on liquid inlet pipe 12 and drain pipe 13 is sealed and installed with protecting cover 6 respectively, and this protecting cover 6 is used for isolating the interior or exterior space of impeller cavity 11.
As required, liquid inlet pipe 12 is provided with main liquid entering hole 121 and time liquid entering hole 122, and this time liquid entering hole 122 diameters are 0.4 times of main liquid entering hole 121 diameters.Wherein, main liquid entering hole 121 and time liquid entering hole 122 places all use protecting cover 6, namely adopt the cover substructure to protect.
The beneficial effects of the utility model are: protecting cover 6 is seal-installed on liquid inlet pipe 12 and the drain pipe 13 opening away from impeller cavity 11, thereby liquid entering hole and the liquid outlet of inside and outside conducting on the impeller cavity 11 are closed, prevent that thus impurity such as external dust from entering in the impeller cavity 11, thereby avoid auto pump inside in transportation process, to be subjected to the intrusion of impurity.This protecting cover 6 is simple in structure, easy to use, and has good sealing effect.
