Description

Technical Field

[0002] A water pump motor is a common industrial device. It drives a water pump through electricity to convey and circulate water. When the water pump motor is in use, since the bearings of the water pump motor are used for a long time, and the temperature of the rear bearing of the water pump motor continues to be on the high side. Refer to Figure 7 , its highest temperature reaches 83.1 °C, and most of the heat is dissipated through the rear end cover. Refer to Figures 5 - 6 , since the rear end cover has no fins and there is no forced ventilation by an axial flow fan, it is found that after the bearing end cover is disassembled, the grease inside the bearing is basically overheated and hardened, and the heat dissipation and lubrication effects are very poor, which will affect the working efficiency of the water pump motor and to a certain extent affect the service life of the water pump motor, which is rather inconvenient.

By welding a number of heat dissipation fins near the bearings on the heat dissipation end cover, the contact area between the heat dissipation end cover and the surrounding air is increased, thereby increasing its heat dissipation area, enhancing the heat dissipation capacity of the heat dissipation end cover, and adding an axial flow fan. The axial flow fan is used to cool the rear bearing of the motor, increase air circulation, play a role in forced heat dissipation, and can also reduce the grease filling of the bearing, further improving the bearing heat dissipation effect.

[0019] See Figures 1 - 4 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a water pump motor 4, a motor rear cover 3 is installed on the rear end of the water pump motor 4, and a heat dissipation end cover 2 is provided on the end surface of the motor rear cover 3. An axial flow fan 1 is in clearance fit with the outside of the heat dissipation end cover 2. Its characteristics are that the heat dissipation end cover 2 includes an end cover body 21, one end of the end cover body 21 is fixedly connected with an end cover flange 22, heat dissipation fins 23 are fixedly connected to the end cover flange 22, and the heat dissipation fins 23 are fixedly connected to the outside of the end cover body 21. A grease filling port 25 is provided on one side of the end cover body 21, and a grease discharge port 26 is also provided on the end cover body 21.

[0020] More specifically, bolt holes 24 are provided on the end cover flange 22, and the heat dissipation end cover 2 is bolted to the motor rear cover 3. When fixing the heat dissipation end cover 2 on the motor rear cover 3, the staff can fix it through bolts in cooperation with its bolt holes 24.

[0021] More specifically, a number of heat dissipation fins 23 are provided and are evenly distributed on the end cover body 21 and the end cover flange 22. The multiple heat dissipation fins 23 can increase the contact area between the heat dissipation end cover 2 and the surrounding air, thereby increasing its heat dissipation area and enhancing the heat dissipation capacity of the heat dissipation end cover 2.

[0022] More specifically, the axis of the axial flow fan 1 corresponds to the axis of the heat dissipation end cover 2. The axial flow fan 1 is used to increase the air circulation effect, thereby increasing the heat dissipation capacity of the heat dissipation end cover 2.

[0023] More specifically, a temperature detection probe is installed at the heat dissipation end cover 2, and the temperature detection probe is electrically connected to the central control system.

[0024] The working principle of the present utility model: When in use, the heat generated by the water pump motor 4 will be conducted to the heat dissipation end cover 2. At this time, the heat dissipation end cover 2 can conduct the heat to the end cover body 21 and the end cover flange 22, and increase the contact area between the heat dissipation end cover 2 and the surrounding air through the heat dissipation fins 23, thereby increasing its heat dissipation area and enhancing the heat dissipation capacity of the heat dissipation end cover 2. And by adding an axial flow fan 1 in front of the heat dissipation end cover 2, the axial flow fan 1 is used to increase the air circulation effect, thereby increasing the heat dissipation capacity of the heat dissipation end cover 2. Among them, the staff should reduce the grease filling of the bearing, which can also further improve the bearing heat dissipation effect, and can reduce the temperature of the rear bearing of the water pump motor 4 to less than 60°C during normal operation, so as to extend the bearing service life and ensure the stable operation of the water pump and ensure the safe operation of continuously supplying water to the power generation boiler.
