(1) The bucket elevator uses the friction torque between the hopper belt and the head wheel drive shaft to lift the material. The tension of the hopper belt is insufficient, which will cause the hopper belt to slip. At this time, stop immediately and adjust the tensioning device to tighten the hopper belt. If the tensioning device does not fully tension the hopper belt, the stroke of the tensioning device is too short and should be readjusted.
The correct solution is to untie the hopper with the joint, adjust the tensioning device on the bottom wheel to the highest position, put the hopper belt into the hoist head, pass the head wheel and the bottom wheel, and connect the head and tail to make the hopper The belt is in a state where it will be tensioned and not tensioned. The tensioning device is then fully tensioned. At this time, the tensioning stroke of the adjusting screw of the tensioning device that has not been utilized should not be less than 50% of the full stroke.
(2) When the hoist overload hoist is overloaded, the resistance torque increases, causing the hopper belt to slip. At this point, the amount of material to be fed should be reduced and the feeding should be uniform. If the amount of feed is reduced, the slippage cannot be improved. It may be that the material in the machine is too much or the hopper is stuck by the instructor. The machine should be stopped for inspection and the fault should be eliminated.
(3) The inner surface of the head wheel drive shaft and the hopper belt is too smooth. The inner surface of the head wheel drive shaft and the hopper belt is too smooth, so that the friction between the two is reduced, resulting in the hopper belt slipping. At this time, a layer of glue can be applied to the inner surface of the drive shaft and the hopper belt to increase the friction.
(4) The rotation of the head and bottom wheel bearings is not working. The rotation of the head and bottom wheel bearings is not working, and the resistance torque is increased, causing the hopper belt to slip. At this time, it is possible to remove and wash the oil or replace the bearing.
Metal Wire
The metal wire including : galvanized wire, stainless steel wire, cutting metal wire, black annealed metal wire, U-type metal wire, PVC metal wire, thin low carbon steel wire, brass wire, nickel wire, etc.
The material of metal wire is metal wire rod & coiled bar and metal bar, the matel wire to be made by wire drawing equipment, annealing equipment and other specialized equipment. Through multi-pass drawing process and annealing, will be processed into different specifications of metal wire .
The metal wire be widely used in industry, agriculture, aquaculture, construction, transportation, mining and other fields .
