The electric hoist of the climbing frame has abnormal noise or sensation, which is usually two parts of abnormal noise and abnormal noise of mechanical conflict. This is the main reason for the abnormal occurrence of the electric hoist of the climbing frame. 1. The abnormal sound of the electric hoist motor of the climbing frame: (1) The sound of the electric hoist of the climbing frame is abnormal during the operation. At this time, you should check whether the single-phase operation of the electric hoist motor of the climbing frame: first, the one-phase power supply is disconnected, and then the motor is broken. In one phase, it is necessary to stop using this condition, otherwise the motor will be easily burned out. (2) The unbalanced three-phase current of the electric hoist motor of the climbing frame will also have abnormal electromagnetic sound. The three-phase current should be monitored carefully, and it should not exceed 10% conventionally. Three-phase current imbalance: one is due to the imbalance of the grid voltage; the second is due to the instantaneous short circuit phenomenon of the customized winding of the motor; the third is the fixed and the rotor air gap is uneven; the fourth is the climbing bar electric hoist rotor has broken bars and thin bars. It is necessary to analyze the motor faults through abnormal sounds, and find a way to deal with them as soon as possible.
Second, the abnormal sound of mechanical conflict: (1) The fixed and rotor friction of the electric hoist of the climbing frame: because the gap between the fixed and the rotor is small, there are often uneven air gaps, iron filings in the motor, burrs, paint film, etc. If the noise is not completely removed, not only the noise is added, but the oscillation will also increase significantly. In severe cases, the core part will overheat and the winding insulation will be damaged. (2) The oil leakage of the bearing of the electric hoist of the climbing frame and the overheating of the bearing: mainly because the bearing grease is too much or too little, the grease is not cleaned in time, the bearing quality is not safe, and many other reasons are formed. -"Sound, the bearing of the electric hoist climbing frame should be disassembled and washed in time, and the appearance of the raceway should be investigated, and then the relevant standards should be checked. In addition to the mechanical failure of the motor of the climbing frame electric hoist, you should also check whether the coupling connected to the reducer of the climbing frame electric hoist is rolling, whether the concentricity meets the requirements, the device is not flat, the shaft is stretched, the transmission unit is unbalanced and other factors Abnormal noise will occur, and the corresponding oscillation will also increase. The user must identify the problem of the motor by hearing the sound and deal with it in a timely manner.
