Firstly, open the end cap of the sand machine, and screw the screw of the removed end cap into two holes specially arranged on the motor end cap of the sand machine equipment to make the cap heavier, and apply the end cap of the lifting equipment and gradually remove it.
Next, first remove the external wiring of the sand machine motor and mark it. For example, for asynchronous motors, markers corresponding to three-phase power lines should be made, and parallel windings and armature windings should correspond to external wiring respectively. Marking. Then loosen the foot screw and separate the motor from the driving mechanism. Then use the pulley or coupling on the motor shaft of the machine equipment. Sometimes kerosene is added to the clearance between the motor axles of the pulley to make kerosene permeate and lubricate, so that it is closely connected with the wheel, and the wheel needs to be quickly heated (while winding the axle) with wet cloth to remove the wheel.
