explosion-proof motor and electrical appliances of explosion-proof electric hoist
Explosion-proof electric hoist is a lifting product suitable for flammable and explosive hazardous occasions, with the characteristics of high safety factor and safe lifting. Many parts of the explosion-proof electric hoist are explosion-proof, among which the motor and electrical appliances are designed for explosion-proof.
The explosion-proof motor of the explosion-proof electric hoist: the hoist uses an explosion-proof cone-rotor motor, which has the characteristics of generating axial magnetic pulling force. The motor uses the axial magnetic pulling force and the action of the spring and brake wheel to make it hoist and brake. Its working principle is: when starting, the magnetic pulling force overcomes the pressure of the brake spring, so that the rotor and the rotor are integrated into the fan brake wheel to produce an axial displacement of about 1-1.5mm. Disengage the brake ring on the brake wheel from the rear end cover, and the rotor runs to reach the working state. When the power is cut off, the magnetic pulling force disappears. Under the action of the pressure spring, the brake wheel and the rear end cover are pressed tightly. The friction torque generated by the moving ring realizes braking in an instant.
Explosion-proof electrical control box, control buttons and electrical principles: The explosion-proof electrical control box is installed on the left side of the reducer or on the opposite side of the operating device and the motor. The power supply enters the box through the soft cable power inlet, and the control box is connected to the Control button, limiter and motor are connected.
