Description

Automobile water pump with water drainage cavity

Technical Field

The utility model belongs to the field of engine cooling water pumps, and particularly relates to an automobile water pump with a water drainage cavity.

Background

The drainage cavity of the automobile water pump refers to a cooling liquid which is designed for ensuring the normal service life of other parts of the water pump assembly and used for storing leakage of a mechanical seal, and has two functions: one is that the cooling liquid which can be normally leaked by the mechanical seal (for lubrication and cooling which meets the sealing requirement) can be stored, so that the misjudgment of the leakage of the water pump by a customer can be avoided; secondly, can in time discover when a large amount of coolant liquid leaked when water pump mechanical seal became invalid, avoid bigger loss.

The design of the volume of the water drainage cavity is designed according to the volatilization amount of the cooling liquid required by the operation of the selected mechanical seal, but most of the leakage of the mechanical seal of the water pump is water vapor, so that the water vapor can not be condensed or volatilized in the water drainage cavity and can overflow the water drainage cavity, some stains (formed by condensation of the cooling liquid) are formed at the opening of the water drainage cavity, and the water pump leakage is misjudged by customers, thereby causing unnecessary loss.

Disclosure of Invention

The utility model provides an automobile water pump with a water drainage cavity, and aims to solve the problem of overflow of condensed water in the water drainage cavity.

In order to solve the technical problems, the technical scheme of the utility model is as follows: an automobile water pump with a water drainage cavity mainly comprises a pump shell, an impeller shaft and a belt pulley, wherein one end of the impeller shaft is rotatably connected with the pump shell through a bearing, the other end of the impeller shaft is fixedly connected with the belt pulley, the belt pulley is used for driving the impeller shaft, and the impeller shaft drives an impeller of the pump shell to rotate; the method is characterized in that: the water drainage cavity on the pump shell consists of an inner cavity and an outer cavity which are communicated, and a drying part is arranged in the inner cavity and used for absorbing liquid in the water drainage cavity.

The technical scheme is further limited, and the drying component is a water-absorbing sponge.

The technical scheme is further limited, and the drying component is blocky activated carbon.

The technical scheme is further limited, and the activated carbon is packaged in the water absorption bag.

The technical scheme is further limited, the drying component is granular silica gel, and the silica gel is packaged in the water absorption bag.

The technical scheme is further limited, a plug is arranged in the outer chamber and used for limiting the drying part.

The technical proposal is further improved, and the plug is distributed with air holes.

Has the advantages that: the drying component in the water discharge cavity of the water pump can ensure that the normally leaked cooling liquid can be absorbed in the water discharge cavity, so that the cooling liquid is prevented from overflowing the water discharge opening to cause the misjudgment of a client; the drying component can also reduce dust in the environment from entering the interior of the water pump, thereby prolonging the service life.

Detailed Description

As shown in fig. 1, an automobile water pump with a water discharge cavity mainly comprises a pump shell 1, an impeller shaft 2 and a belt pulley 3, wherein one end of the impeller shaft is rotatably connected with the pump shell through a bearing 4 and a water seal 5, the other end of the impeller shaft is fixedly connected with the belt pulley, the belt pulley is used for driving the impeller shaft, and the impeller shaft drives an impeller 6 in the pump shell to rotate; the water drainage cavity on the pump shell consists of an inner cavity 7 and an outer cavity 8 which are communicated, and a drying part 9 is arranged in the inner cavity and is used for absorbing liquid in the water drainage cavity; the water drainage cavity can also be understood as a water leakage observation hole;

as shown in fig. 2, the drying component 9 is a water-absorbing sponge, which has the advantages of strong water absorption and low production cost;

as shown in fig. 3, the drying component 9 is a block-shaped activated carbon, which has the advantages of strong water absorption, low production cost and longer service life than sponge;

as shown in fig. 3, the activated carbon is packaged in a water absorption bag 11, which is made of water absorption non-woven fabric; after the activated carbon is used for a long time, carbon residue is easy to generate, and the water-absorbing non-woven fabric is used for preventing the carbon residue from entering the water pump and has good water absorption and air permeability;

as shown in fig. 4, the drying component is granular silica gel, and the silica gel is packaged in the water absorption bag 10; the silica gel has strong water absorption, low production cost and long service life;

as shown in fig. 1 and 5, a plug 11 is arranged in the outer chamber and used for limiting the drying part; the drying part is fixed in a detachable mode, so that the assembly and later maintenance are convenient, and the modification of the existing product is facilitated;

as shown in fig. 5, the air holes 12 are distributed on the plug to facilitate the air flow, thereby accelerating the drying speed of the drying part.

The engine cooling water pump comprises a pump shell, an impeller shaft, a belt pulley, an impeller, a water seal, a pump shell cover and other parts; since the structure and operation principle of the engine cooling water pump are well known in the art, and the technical problem to be solved by the present invention is only related to the pump casing, the structure of the engine cooling water pump is not described in detail.
