An electronic water pump for an engine

Abstract

The invention discloses an engine electronic water pump, which comprises a water pump shaft. One end of the water pump shaft is connected to a water pump motor, and the other end is fixed with a water pump wheel through a key. The water pump blade shaft is independently controlled by the water pump blade motor. The water pump blade shaft transmission gear installed on the water pump shaft near the end of the water pump housing drives the water pump blade shaft to rotate, the water pump blade is fixedly installed on the water pump blade shaft, and the water pump blade power gear is installed on the water pump shaft near the end of the water pump housing. The water pump motor transmits power to the water pump blade power gear through the motor output gear, and the water pump blade shaft gear is fixedly installed on the outer circumference of the water pump blade shaft transmission gear, and the water pump blade shaft gear and the water pump blade are an integral structure. The engine electronic water pump with the above-mentioned special structure continuously adjusts the accuracy of the water pump blades through the motor, thereby controlling the temperature and flow of the engine cooling water, so that the engine can obtain the best cooling effect.

Description

technical field [0001] The invention relates to an electronic water pump for an engine, in particular to an electronic water pump structure with electronically controlled variable blades. Background technique [0002] With the advancement of electronic technology, the current vehicle control technology has been largely electronicized to achieve the best control function of the system and the energy-saving benefits of the engine. But so far, most of the car engine cooling systems have been using mechanically controlled thermostats and cooling water pumps. Except for cooling fans, other parts have not used electronic control. [0003] The traditional mechanical cooling system mainly includes mechanical water pumps, hot wax thermostats, radiators, and cooling fans. At the same speed, only one set amount of cooling water can be provided, and it is impossible to provide the optimal cooling water control according to different engine loads. Therefore, it is necessary to design an...

Problems solved by technology

[0003] The traditional mechanical cooling system mainly includes mechanical water pumps, hot wax thermostats, radiators, and cooling fans. At the same speed, only one set cooling water volume can be provided, and the optimal cooling water volume control can not be provided according to different engine loads. Therefore, the cooling water volume should be designed according to the maximum load heat dissipation of the engine.

In this way, under partial load, the following problems are often caused by excessive cooling water: 1. The mechanical cooling water pump cannot optimally control the heat dissipation demand of the engine; 2. The temperature of the engine oil decreases, the viscosity increases, and the engine power loss increases
