A new energy vehicle battery cooling water circulation pump

Abstract

The invention relates to the field of circulation pumps, in particular to a new energy vehicle battery cooling water circulation pump. The new energy vehicle battery cooling water circulating pump includes a pump body, and a rotating shaft is installed away from the axis, and one end of the rotating shaft extends out of the pump body and is provided with a fixedly connected pulley flange; the pump cover is closed On the pump body, the water inlet pipe and the water outlet pipe are installed on the pump cover; the assembly part is located on the rotating shaft in the pump body, and the impeller blade is installed through the assembly part, the assembly part includes a shaft cylinder, and the shaft The cylinder is fixedly installed on the rotating shaft through a coupling, and a sleeve is installed in the shaft cylinder. The new energy vehicle battery cooling water circulation pump provided by the present invention has impeller blades compared with the traditional integral impeller structure, which reduces the difficulty of the preparation process, and can be replaced independently after a single impeller blade is damaged, without abandoning the entire impeller structure , more economical and practical advantages.

Description

technical field [0001] The invention relates to the field of circulating pumps, in particular to a new energy vehicle battery cooling water circulating 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 units, and the integration of advanced technologies in vehicle power control and drive, resulting in advanced technical principles and new technologies. , New structure vehicles, new energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, etc. [0003] Since the main job of the new energy vehicle cooling system is to dissipate heat into the air to prevent the engine from overheating, the cooling system also has other important roles. Engines in cars run best at moderately high temperatures. If the engine gets cold, the components wear out faster, which ma...

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.
