The Belt Sway Switch functions in detecting any deviation or sway in the conveyor belt and providing an auto-alarm and sending out signal to stop the conveyor to avoid the damage to the conveyor belt and prevent scatter of conveyed materials because of the belt distortion. The Belt Sway Switch is necessary in the safe conveying system, widely used in the belt deviation detection of the belt conveyor for coal, cement and building materials, mining, electricity, port, metallurgy and chemical industries ●The Belt Sway Switch functions in two levels: One for auto-alarm, and the other for auto-stop.
●During the operation of the belt conveyor, when the belt sways and touches the vertical roll, the roll turns on its axis; When the belt sways abnormally, it will squeeze the vertical roll and make it offset. When the vertical roll is at 20slant, the first level switch function may send the alarm signal. When it continues to be at 35 slants, the second level switches function works to send the stop signal.
●After the fault clearing, the belt departs from the vertical roll and operate normally, the roll may reset automatically.
●The Belt Sway Switch of Fischer is constructed with high reliability microswitches, lubricateless ball bearings, a touch roller which is titled to 75 , and other parts; its functions are designed with a large margin for sure action and long life
Prevention with slant on both sides of the switch should be installed on the conveyor maintenance channel, installation position should ensure that maintenance personnel in the event of an emergency operation is convenient
●Belt sway switch is located in the conveyor belt on both sides, vertical roll with conveyor belt edge perpendicular to the plane, and on both sides of the conveyor belt is located at 1/3 height of vertical roll.
●Belt sway switch and vertical roll conveyor belt normal position of the appropriate spacing is 50 ~ 100 mm.
●belt sway switch quantity should be according to the length of the conveyor, types and arrangement for sure. Should be in commonly conveyor head, tail, convex segmental arc, concave segment and location in the middle of the conveyor is set. (Note: when the conveyor is longer, the position in the middle of the conveyor can every 30~35 m set to 1)
●The partial belt sway switch should through the mounting bracket and conveyor frame connection; switch bracket shall be installed on the conveyor and conveyor frame welding, after the completion of switch and switch bracket bolted
