Abstract
The utility model discloses an automotive water pump with a mute device, which comprises a bearing with a shaft and a frame. A water pump is fixedly connected with the frame, a water seal and an impeller are arranged in the water pump, and the mute device is disposed outside the frame. As cap-shaped foam rubber is used for wrapping the frame, sound absorption through holes in the foam rubber can effectively absorb noise produced by the pump, and comfort of an automobile user is greatly improved.
Description
Technical field
The utility model relates to a kind of pumping plant, or rather, is a kind of auto pump with silencing apparatus.
Background technique
Motor car engine extensively adopts Centrifugal water pump.Its basic structure is made up of parts such as water pump cover, land or belt pulley, water pump spindle and bearing or shaft connecting bearing, water pump vane and water seal arrangements.Motor drives water pump bearing and wheel rotation through belt pulley, and the cooling liquid in the water pump is driven rotation together by impeller, under action of centrifugal force, is thrown toward the edge of water pump cover, produces certain pressure simultaneously, flows out from water outlet or water pipe then.Pressure reduces because cooling liquid is thrown out of in the center of impeller, and the cooling liquid in the water tank is inhaled in the impeller through water pipe under the differential pressure action at water pump import and impeller center, realizes the reciprocation cycle of cooling liquid.
The pump housing of existing auto pump is exposed, can send very big noise at running, has a strong impact on user's comfort level.
The model utility content
The utility model mainly is to solve the existing in prior technology technical problem, thereby a kind of auto pump with silencing apparatus is provided.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of auto pump with silencing apparatus comprises shaft connecting bearing and profile, and a water pump body is fixedly connected with described profile, is provided with a water seal and an impeller in the described water pump body, and the outside of described profile is provided with a silencing apparatus.
As the preferred embodiment of the utility model, described silencing apparatus is the spongy rubber of a cap shape, described spongy rubber wrap up described profile outer surface and with described profile adhering junction.
As the preferred embodiment of the utility model, the center of described silencing apparatus is provided with a sound-absorbing through hole, and described shaft connecting bearing is arranged in the described sound-absorbing through hole.
Because the auto pump of the band silencing apparatus of the utility model utilizes the spongy rubber parcel profile of cap shape, utilizes the sound-absorbing through hole in the spongy rubber simultaneously, can effectively absorb the noise that the pump housing sends, and has improved the comfort level of autoist greatly.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of auto pump of the band silencing apparatus of the utility model.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
The utility model provides a kind of auto pump with silencing apparatus.
As shown in Figure 1, a kind of auto pump with silencing apparatus comprises shaft connecting bearing 1 and is fixedly connected with this profile 2 with profile 2, one water pump bodys 3, is provided with a water seal 4 and an impeller 5 in this water pump body 3, and the outside of this profile 2 is provided with a silencing apparatus 6.
This silencing apparatus 6 is the spongy rubber of a cap shape, the outer surface of this profile 2 of this spongy rubber parcel and with these profile 2 adhering junctions.
The center of this silencing apparatus 6 is provided with a sound-absorbing through hole 61, and this shaft connecting bearing 1 is arranged in this sound-absorbing through hole 61.
The auto pump of the band silencing apparatus of this model utility utilizes the spongy rubber parcel profile of cap shape, utilizes the sound-absorbing through hole in the spongy rubber simultaneously, can effectively absorb the noise that the pump housing sends, and has improved the comfort level of autoist greatly.
The mentality of designing of the utility model below only is described with a mode of execution, and under the situation that system allows, the utility model can expand to external more function module simultaneously, thereby expands its function to greatest extent.
The above is merely the embodiment of the utility model, but the protection domain of the utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
