Problems solved by technology

[0002] In the related technologies of cooling water pumps, most of them are fixed mechanical structures, and their impellers and covers are fixed, so the flow rate of the water pump is also fixed and cannot be adjusted according to the actual situation.
Usually, in order to adjust the flow of the water pump, the speed of the impeller of the water pump is controlled by the controller, but the reliability of the control equipment using the controller is low

Abstract

The invention provides a cooling water pump and an engine, wherein the cooling water pump comprises an output shaft; an impeller fixedly arranged on the output shaft, wherein the impeller comprises abase and blades arranged on the base, wherein the base is provided with at least one containing cavity, and a temperature-sensing expansion piece is arranged in the containing cavity; an impeller cover arranged on the output shaft, wherein the impeller cover can move relative to the output shaft, the impeller cover is arranged on the impeller, a part of the blades extend out of the impeller cover,and the impeller cover is provided with a limit lug which is matched and connected with the containing cavity; and the limit lug is inserted into the containing cavity, so that the temperature-sensing expansion piece is hermetically arranged in the containing cavity. According to the embodiment of the invention, the flow of the water pump is adjusted according to the water temperature through theimprovement of the structure, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of auto parts design, in particular to a cooling water pump and an engine. Background technique [0002] In the relevant technologies of cooling water pumps, most of them are fixed mechanical structures, and their impellers and covers are fixed, so the flow rate of the water pump is also fixed and cannot be adjusted according to actual conditions. Usually, in order to adjust the flow rate of the water pump, the speed of the impeller of the water pump is controlled by the controller, but the reliability of the control equipment using the controller is low. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a cooling water pump and an engine for adjusting the flow of the water pump according to the water temperature through a mechanical structure. [0004] In order to solve the above technical problems, an embodiment of the present...
