Abstract

The invention discloses a water pump. The water pump comprises a shell, a rotor assembly (14), a water guide pipe (10) and a power device, wherein the rotor assembly (14) is rotationally arranged in the shell and provided with a water cooling channel penetrating through the two ends of the rotor assembly (14); the water guide pipe (10) is arranged outside the shell, one end of the water guide pipe (10) is communicated with one end of the water cooling channel, and the other end of the water guide pipe (10) is communicated with the other end of the water cooling channel; the power device is used for driving cooling water to flow in a channel formed by the water guide pipe (10) and the water cooling channel. According to the water pump, as the water cooling channel is formed in the rotor assembly, under the action of the water guide pipe and the power device, the cooling water passes through the rotor assembly to take heat generated by rotation of a motor of the water pump away, the heat dissipation efficiency of the motor is improved, the temperature of the motor is reduced, the efficiency of the motor is effectively improved, and the working efficiency of the water pump is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, more specifically, to a water pump. Background technique [0002] The water pump includes a turbine and a motor. Under the action of the motor, the turbine is driven to rotate so as to form a negative pressure in the volute of the water pump and achieve the function of transferring water to the outside. [0003] However, under the continuous operation of the water pump, the temperature of the motor increases accordingly, especially the rotor assembly located at the center of the motor has a high temperature and poor heat dissipation performance, so that the temperature of the motor is relatively high. The temperature of the motor affects the efficiency of the motor, which in turn affects the working efficiency of the water pump. [0004] To sum up, how to improve the heat dissipation efficiency of the motor and the working efficiency of the water pump is an urgent problem to be solve...
