Description

[0002] In the field of water pump motors, as flow demand continues to increase, high-flow water pump motors are increasingly used. However, traditional water pump motors often have some problems during operation, especially the loosening of fixing bolts due to working vibration, which seriously affects the stability of water pump motors.

[0003] Traditional water pump motors usually use a simple bolt fixing method to fix the motor body to the mounting base or bracket. However, under long-term, high-load working conditions, the vibration of the motor body can easily cause the fixing bolts to loosen, which in turn causes the motor body to shift, tilt or even fall off, causing damage to the equipment and safety hazards. Therefore, in order to solve the problem of loose fixing bolts mentioned above, the utility model proposes a large-flow water pump motor. Utility Model Content
