Water pump assembly device

Abstract

The invention discloses a water pump assembly device. The water pump assembly device comprises a pump shell body, an impeller cavity is formed in the middle of the pump shell body, and the pump shellbody further comprises a water inlet part, a water outlet and a pump body mounting pipe. The water inlet part, the water outlet and the pump body mounting pipe communicate with the impeller cavity, the lower end of the impeller cavity is open, a sealing cover is fixed to the lower end of the impeller cavity through bolts to seal the lower end of the impeller cavity, and one end of the water inletpart communicates with the middle of the upper end of the impeller cavity. The lower end of the pump body mounting pipe is open in the middle of the upper end of the impeller cavity, and the water outlet is open in one side surface of the impeller cavity. A driving shaft, an inner integral ball bearing and a water sealing structure are mounted in the pump body mounting pipe, a cooling water pump impeller is arranged in the impeller cavity, and the driving shaft penetrates through the shaft connecting bearing and the water sealing structure and is connected with the cooling water pump impeller.The water pump assembly device has the advantages of anti-vibration, long service life and simple structure.

Description

technical field [0001] The invention belongs to the technical field of auto parts equipment, and in particular relates to a water pump assembly device. Background technique [0002] Automobile water pump is an important part of automobile, it is based on traditional vane pump technology. The water exchange pump for vehicles is mainly composed of shaft-connected bearings, housings, water seals and impellers. [0003] The water seal seals the pump shaft. The automobile water seals currently on the market mainly have the following deficiencies: 1. When used for a long time, the contact between the rotating ring and the stationary ring gradually wears out until automatic compensation cannot be realized, resulting in 2. As the pump shaft continues to stir the water, it will generate periodic vibrations, causing the contact surfaces of the rotating ring and the stationary ring to rub back and forth horizontally, which accelerates the wear of the rotating ring and the stationary r...

Problems solved by technology

[0003] The water seal seals the pump shaft. The automobile water seals currently on the market mainly have the following deficiencies: 1. When used for a long time, the contact between the rotating ring and the stationary ring gradually wears out until automatic compensation cannot be realized, resulting in 2. Due to the continuous stirring of the pump shaft, periodic vibrations will be generated, causing the contact surface of the rotating ring and the stationary ring to rub back and forth horizontally, which accelerates the wear of the rotating ring and the stationary ring

When foreign objects fall into the impeller cavity and need to be cleaned due to cooling water sundries, rust in the circulating water system, etc., the general water pump impeller is very difficult to disassemble, resulting in high maintenance costs
