Some precautions for the maintenance of mine winch,Underground Mining Winch
1. When the service life of the bearing of the Underground Mining Winch ends, the vibration and noise of the motor operation will be significantly expanded. When the axial backlash of the bearing of the Underground Mining Winch reaches the following value, the bearing of the mine winch should be replaced.
2. When disassembling the motor of the mine winch, the motor rotor can be removed from the shaft extension end or the non-extension end. If there is no need to remove the fan of the Underground Mining Winch, or from the non-axial end to remove the motor rotor is more convenient, from the motor stator out of the motor rotor, should avoid destroying the motor stator of the Underground Mining Winch winding resistance or insulation layer.
3 Mine winch dismantling winding resistance must be recorded the way of the original coil, specifications and coil turns, line rail, etc., should be asked to the production plant, casually change the original design of the mine winch winding resistance, often make the Underground Mining Winch motor some or several characteristics of evil change, even can not be applied.
The above is the maintenance of Underground Mining Winch some matters needing attention.
