Fault handling of electric gourd
The gap between the rotor or stator of the motor is too small. Factory products are not allowed to the chamber "sweep", "chamber" of the main reason is that: the motor shaft bearing ring wear and axial displacement of rotor iron core, or a custom core displacement. Remove and replace the supporting ring, make the rotor cone of the stator rotor have even clearance, each side is 0.35 ~ 0.55 mm (small motor space small) or send back to the manufacturing factory for repair.
After start-up, the motor does not turn and cannot lift heavy objects Overloading is not allowed The voltage is over 10% below the rated voltage and the voltage is back to normal There is a malfunction of the electrical equipment, the wire is disconnected or the contact is bad, and the electrical equipment and the circuit are repaired The brake wheel and the rear end are corroded, the brake wheel is not open, the brake wheel is removed, and the surface is cleaned and corroded The machine was cleaned and cleaned, and handled by the order no. 9 The conductor is too thin to replace the conductor
Speed reducer leakage Between the case and the box cover, the sealing ring is defective or damaged, and the sealing ring is removed or replaced The connection screw is not tightened and the screw is tightened You can go on and on and on
The brake is unreliable, the drop distance exceeds the requirement Because of the large or other causes of the brake ring, the spring pressure is reduced and the spring pressure is adjusted The design of the brake ring and the back end of the cover is bad, and the grinding is removed The brake surface is oily and removed and cleaned The brake ring is loose and the brake ring is changed Pressure spring fatigue, replace spring The shaft coupling is run by an inspirit or card and checks the join section The conical rotor is outsized by the regulation
The motor is heating up The use of overloading is used The assignments are too frequent and the number of assignments is reduced The gap is too small and the brake ring is not completely removed when it is running, which is equivalent to the additional load. To readjust
