Magnetic separator is one of the important mineral processing equipment, mainly used for ferrous metal ore dressing - magnetic separation of iron ore; colored and rare metal ore selection - tungsten and tin separation, copper and molybdenum separation, copper and lead separation; heavy medium beneficiation Medium magnetic re-election of magnetic media recovery; non-metallic mineral raw materials beneficiation to remove iron impurities - kaolin iron removal; wastewater treatment. Whether it is dry magnetic separator or wet magnetic separator basically all-weather operation. This gives a great load on the magnetic separator machine motor, how to ensure that the motor does not appear in the operation of burning, power failure and other failures? Here are six types of magnetic separator motor maintenance measures. one. Always keep the motor clean Motor in operation, at least 3 meters around the air inlet Do not allow dust, water stains and other debris to prevent inhalation of the internal motor, the formation of short circuit medium, or damage the wire insulation, resulting in short circuit between the box, Current increases, the temperature increases and burned the motor. two. Maintain the motor is often under rated current overload motor operation, mainly due to drag the load is too large, the voltage is too low, or caused by the mechanical jamming caused. If the overload time is too long, the motor will absorb a large amount of active power from the power grid, the current will increase sharply, the temperature will also rise, the motor insulation at high temperatures will aging failure and burned. Therefore, the motor is running, we should pay attention to constantly check the transmission operation is flexible and reliable; the concentricity of the coupling is standard; gear transmission flexibility, if there is a phenomenon of stuck, stop immediately find out the cause of the problem After running. three. Check the motor three-phase current is balanced three-phase asynchronous motor, the phase current of any phase current and the other two-phase current difference does not allow more than 10%, so as to ensure the safe operation of the motor. If more than that indicates that the motor is faulty, you must find out the reasons for the timely exclusion. four. Check the motor temperature To always check the motor bearing, stator, shell and other parts of the temperature without exception, especially for voltage, current and frequency monitoring and no overload protection of the motor, the temperature rise is more important to monitor. If found near the motor bearing temperature is too high, it should immediately stop checking. Bearing rolling body, raceway surface cracks, scratches or loss, bearing clearance is too large shaking, the inner ring on the shaft whether rotation. Any of these phenomena, you must update the rear bearing can be re-operated. Fives. Check whether the motor vibration, noise and abnormal odor If the motor vibration occurs, it will cause the load part of the connection is not concentricity increase, the formation of the motor load increases, the overload operation, it will burn the motor. Therefore, the motor in operation, especially high-power motor should always check the anchor bolts, motor cover, bearing gland and other loose, grounding device is reliable and found to solve the problem in time.
