Abstract

The invention relates to the technical field of engine cooling, and discloses an engine water pump which comprises a pump body, a motor, an impeller, a controller and a temperature collecting pipe, the pump body is provided with a pump cavity, a water inlet and a water outlet, the water inlet and the water outlet are communicated with the pump cavity, and the impeller is installed in the pump cavity and connected with a rotor of the motor through a transmission shaft. The temperature collecting pipe is used for collecting the water temperature in the pump cavity, the controller is fixed to the pump body, the temperature collecting pipe is fixed to the controller, and the controller is electrically connected with the temperature collecting pipe and the motor and controls the rotating speed of a rotor of the motor according to water temperature data collected by the temperature collecting pipe. The invention further discloses an engine water pump control method. The temperature collection and control functions are integrated on the water pump body, the overall integration degree of the water pump is improved, a transmission line of water temperature data and control signals is shorter, feedback is more timely, the function of adjusting the water temperature of an engine in real time is achieved, and it is guaranteed that the engine cannot be overheated under all operation working conditions.

Description

technical field [0001] The invention relates to the technical field of engine cooling, in particular to an engine water pump and a control method thereof. Background technique [0002] At present, the cooling system is an important part of the engine, and the water pump as the cooling power of the engine is the mainstream development direction. Usually, the electronic control unit of the engine collects the water temperature through the water temperature sensor for integrated judgment, and then transmits the command to the water pump to control the speed of the motor and the flow of coolant, thereby adjusting the water temperature of the engine. The arrangement may cause technical problems such as water temperature data and control signal transmission failure, response delay and other technical problems due to the long transmission route. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an engine water pump and a control method thereof,...
