Cooling water circulating pump for storage battery of new energy automobile

Abstract

The invention relates to the field of circulating pumps, in particular to a cooling water circulating pump for a storage battery of a new energy automobile. The cooling water circulating pump comprises: a pump body, wherein a rotating shaft is rotationally connected to the position deviating from the axis, and one end of the rotating shaft extends out of the pump body and is sleeved with a fixedly-connected belt wheel flange; a pump cover covering the pump body, wherein a water inlet pipe and a water outlet pipe are mounted on the pump cover; and an assembly part which is located on the rotating shaft in the pump body, wherein impeller blades are installed through the assembly part, the assembly part comprises a shaft barrel, the shaft barrel is fixedly installed on the rotating shaft through a coupling, and a sleeve is installed in the shaft barrel. Compared with a traditional integral impeller structure, the cooling water circulating pump for the storage battery of the new energy automobile has the advantages that the difficulty of a preparation process is reduced, the single impeller blade can be independently replaced after being damaged, the whole impeller structure does not need to be abandoned, and the cooling water circulating pump is more economical and practical.

Description

technical field [0001] The invention relates to the field of circulation pumps, in particular to a new energy vehicle battery cooling water circulation pump. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources or the use of conventional vehicle fuels, the use of new vehicle power devices, and the comprehensive vehicle power control and advanced technology in driving, forming advanced technical principles and new technologies. , new structure of the car, new energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles and so on. [0003] Since the main job of the cooling system of new energy vehicles is to dissipate heat into the air to prevent the engine from overheating, the cooling system also has other important functions. Engines in cars run best when they are moderately hot. Another important role of the cooling system is to warm up the eng...

Another important role of the cooling system is to warm up the engine as quickly as possible and keep it at a constant temperature

[0004] As the "heart" of the cooling system, the circulation pump is very important. The impellers of the current mechanical water pumps are all integral structures. When the impeller is impacted by the coolant or the pump body vibrates greatly due to external reasons, the blades on the impeller It is easy to be damaged, which leads to poor effect of the circulating pump. It needs to be discarded as a whole when it is replaced later, and the economic benefit is poor. At the same time, when the shaft on which the impeller is installed is subjected to a large torque, the stability of the impeller is also easily affected.
