Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of automobile engine water pump, especially a kind of automobile water pump assembly of water vapor easy to discharge. BACKGROUND

[0002] The water discharge cavity of automobile water pump refers to the storage of mechanical seal leakage cooling liquid designed to ensure the normal service life of other components of water pump assembly, which has two functions: one is to store the cooling liquid normally leaked by mechanical seal (lubricating cooling required for sealing), and evaporate in time, which will not cause excessive accumulation of cooling liquid to damage bearing seal and customer misjudgment of water pump leakage;Second, when the mechanical seal of water pump fails, a large amount of cooling liquid can be found in time to avoid greater loss.

[0003] The design of the volume of the water discharge cavity is based on the volatilization amount of the cooling liquid required for the operation of the selected mechanical seal, but most of the leakage of the mechanical seal of the water pump is water vapor, so the water vapor cannot condense or volatilize in the water discharge cavity, and will overflow the water discharge cavity, forming some stains (formed by condensation of cooling liquid) at the outlet of the water discharge cavity, causing customer misjudgment of water pump leakage and unnecessary loss;At the same time, more water vapor aggregation will have a certain impact on the sealing of the bearing, causing the bearing to be loose. CONTENT OF THE UTILITY MODEL

[0004] The utility model provides a kind of automobile water pump assembly of water vapor easy to discharge, to solve the problem that water vapor in water discharge cavity is not easy to discharge.

[0005] To solve the above technical problems, the technical scheme of the utility model is: a kind of automobile water pump assembly of water vapor easy to discharge, including water pump body, water pump body is equipped with water discharge hole;Characterized in that: it further includes drainage pipe, drainage pipe is composed of a transverse pipe and cooling pipe, transverse pipe is fixed by fastener on water pump body, cooling pipe is fixed on water pump body by support, and cooling pipe is communicated with water discharge hole on water pump body by transverse pipe.

[0006] The above technical scheme is further limited, and the cooling pipe is a spiral pipe body.

[0007] The above technical scheme is further limited, and the structure of the fastener includes bolt and gasket, the gasket is pressed on the water pump body after the bolt is fastened, and the gasket extends outward on one side to pipe clamp, and the pipe clamp is used for clamping the transverse pipe.

[0008] The above technical scheme is further limited, and the water pump body is provided with pipe joint at water discharge hole, and the pipe joint is used for connecting transverse pipe.

[0009] The above technical scheme is further limited, and the transverse pipe and the cooling pipe are metal pipes.

[0010] Beneficial effects: the utility model discloses a drainage tube of intercommunication drain cavity can discharge the water vapor in drain cavity in time, is favorable to reduce the steam in drain cavity to the bearing seal of the damage, reduces the quality problem and compensation of after-sales service after the sale;Drainage tube can avoid the dirt of water vapor in drain cavity mouth because of condensation to form, thereby reduce the customer misjudgment.

[0015] As Figure 1 , Figure 2 and Figure 3 indicated, a kind of water vapor easy to discharge automobile water pump assembly, including water pump body 1 and drainage tube, wherein drainage tube is made of a cross pipe 2 and cooling pipe 3;The water pump body is equipped with drain hole, and pipe joint 4 is arranged at drain hole, and pipe joint is used to connect the import end of cross pipe, and it is beneficial to later maintenance to adopt pipe joint connection;The outlet end of the cross pipe is fixedly connected with fastener 5 on the water pump body, and the cooling pipe is fixed on the water pump body by support 6, and the import end of cooling pipe is communicated with the outlet end of cross pipe;

[0016] As Figure 1 , Figure 2 and Figure 3 indicated, further, the cooling pipe is spiral pipe body;Adopt spiral pipe body, both can increase the path of water vapor, and do not occupy larger space;

[0017] As Figure 3 and Figure 4 indicated, further, the structure of fastener 5: including bolt 51 and gasket 52, bolt and water pump body 1 fastening connection will gasket be pressed tightly on water pump body, and gasket one side extends outward after pipe clamp 53, and pipe clamp is used for clamping cross pipe;Advantages: 1) this structure is simple, and production cost is low, and universality is strong, is favorable to the reform of existing water pump body;2) adopt clamping mode, and it is convenient to dismount, and it is beneficial to later maintenance;

[0018] Further, the cross pipe and the cooling pipe are metal pipes; 1) the metal pipes can avoid the problem of shaking due to vibration, thereby avoiding interference with other parts and also being conducive to prolonging the service life; 2) the metal pipes have good heat conduction and are easy to absorb heat, and the pipe body can promote effective discharge of water vapor after being heated.

[0019] The water discharge cavity in the water pump body can increase the discharge pressure through the drainage pipe, thereby accelerating the water vapor discharge speed; in order to avoid corrosion of the surrounding parts by a large amount of discharged water vapor, the cooling pipe in a spiral shape is used to cool the discharged water vapor, condensed water is attached to the pipe wall of the cooling pipe, full volatilization is facilitated, and the discharge speed of the water discharge cavity is not affected.
