Galvanized roller conveyors are specialized for transporting various types of boxes, pallets, and other packaged items. Loose materials, small objects, or irregular items need to be placed on pallets or transport containers in order to be conveyed. It is capable of transporting materials with large individual weights, or handling high impact loads. Galvanized roller conveyors may develop problems if proper care and maintenance are not carried out over time due to their prolonged use. Abnormal noises: During operation, belt conveyors emit abnormal noises when their drive equipment, drive rollers and idler rollers, as well as the roller sets, are not functioning properly. By analyzing these abnormal noises, it is possible to identify faults in the equipment. Noise when the idlers of zinc-plated roller conveyor accessories are severely damaged: Abnormal noise often occurs in the idlers of zinc-plated roller conveyors during operation, accompanied by periodic vibrations. Especially the return idler rollers, due to their large length, have significant self-weight and generate considerable noise as well. There are mainly two factors that cause noise during an attack. First, the wall thickness of the seamless steel tubes used to manufacture galvanized drums is uneven, resulting in a relatively large centrifugal force. Secondly, during processing, the error between the bases of the bearing holes at both ends of the galvanized drum and the center of its outer circle is relatively large, resulting in excessive centrifugal force. It can continue to be used as long as the galvanized roller bearings are not damaged and noise is present. The noise that occurs when the two shafts of a galvanized drum coupling are not aligned is an abnormal sound heard at the coupling between the motor on the high-speed side of the drive equipment and the reducer, or at a coupling equipped with brake wheels; this noise is also accompanied by oscillations at the same frequency as the motor’s rotation frequency. When such noise occurs, the position of the motor reducer should be adjusted promptly to prevent cracking of the reducer’s input shaft. Abnormal noises from the redirecting galvanizing drum and the driving galvanizing drum; these drums produce very little noise when operating normally. Abnormal noises usually indicate damaged bearings, with a grinding sound coming from the bearing housings, and in such cases the bearings need to be replaced.
