The water pump has motor components to drive the water pump to work. If it is not started for a long time, the equipment is prone to corrosion, which makes the initial starting torque of the motor rotor shaft large, so the motor current when starting will also be large, which may easily cause the motor to start overload And damaged. Next, follow the editor of УРАП Water pump to learn about the production method of water pump motor parts.
1. Through the design of the dial groove at the end of the rotor shaft and the through hole design in the middle of the wind hood, it is possible to use a tool to move the dial groove through the through hole before starting the water pump, and then start the motor after the rotor shaft can be rotated. As a result, the initial starting torque of the motor rotor shaft will not be very large, so the motor current when the water pump is started will also be controlled within a reasonable range, so as to prevent the motor from starting overload and damage.

2. When the water pump is working, even if the water in the pump leaks out through the mechanical seal, it will reach the water retaining ring first. The water retaining ring will throw the water out under the high-speed circular motion of the rotor shaft and pass through the water retaining ring. The opening at the bottom of the space flows out, so it will not reach the bearing position, so the waterproof reliability of the motor is good.
Because the bearings of the water pump are compressed by bolts with pads to achieve axial positioning, the rotor shaft of the motor can also get good axial positioning. The axial series momentum of the rotor shaft is small when it is working, so the motor has good working stability. .
The above is the introduction of the editor of УРАП Water pump: the knowledge about the production method of water pump motor parts.
