During the use of existing centrifugal pumps, the drive motor will heat up after long-term use. Failure to dissipate heat in time will cause damage to the motor. At the same time, most existing centrifugal pumps use a single fan to assist in heat dissipation, but the fan blades are not easy to clean and disassemble, resulting in a slow heat dissipation rate, which affects the heat dissipation effect. Summary of the invention

[0003] The purpose of the utility model is to provide a high-strength heat dissipation centrifugal pump to solve the above problems in the prior art.

The connecting frame, the protective net and the heat dissipation fan are installed on the mounting platform by fastening screws.

[0007] A plurality of heat dissipation ribs are provided on the outside of the drive motor and extend radially outward to improve the heat dissipation effect. Ventilation holes are provided on the corresponding outside of the drive motor to quickly volatilize heat.

[0008] The high-strength heat-dissipating centrifugal pump also includes a base for mounting a driving motor and a pump body, and the base is provided with a plurality of shock-absorbing feet for supporting the driving motor and having a shock-absorbing effect.

[0009] In the above-mentioned high-strength heat-dissipating centrifugal pump, a rubber pad for reducing the working vibration noise of the driving motor is also arranged at the bottom of the shock-absorbing foot, and the rubber pad is sleeved on the shock-absorbing foot.

[0010] In the above-mentioned high-strength heat dissipation centrifugal pump, a plurality of heat dissipation ribs are arranged and distributed along the outer wall of the driving motor in a circumferential direction at intervals and are divided into two groups. The heat dissipation ribs and the outer wall of the driving motor are arranged as an integrally formed structure.

[0011] In the above-mentioned high-intensity heat dissipation centrifugal pump, the heat dissipation device and the exterior of the driving motor are arranged as a split-type detachable structure, and are fixed and disassembled by fastening screws, which is convenient for later maintenance, cleaning and replacement.

[0012] In the above-mentioned high-intensity heat dissipation centrifugal pump, the number of the heat dissipation fans is 2, and the heat dissipation fans, heat dissipation holes, ventilation holes and heat dissipation rib structures cooperate to achieve rapid volatilization and heat dissipation inside the drive motor.

[0013] Compared with the existing technology, the high-strength heat-dissipating centrifugal pump has a simple structural design. The base, shock-absorbing feet and rubber pads are used to effectively strengthen the support for the drive motor, ensure the stable installation between the drive motor and the base, and avoid the instability between the connection with the pump body caused by the vibration of the drive motor.
