Belt sway switch is used to check the belt running deviation of the belt conveyor, it is a safe protection device of automatic alarm and stop when the belt running deviation appears.Belt sway switch is fixed on the conveyor belt bracket, action bar is at the side of the belt, when the belt running deviation appears, force the action bar deviation, and touch the alarm micro switch. If the belt running deviation continues,will touch another group of contact, and the conveyor will be protective to stop.
In the installation and adjustment of belt sway switch, what matters should we pay attention to? PK Machinery will answer for you!
1. Belt sway switch should be located on both sides of the conveyor belt, the vertical roll should be vertical with conveyor belt edge flat, and both sides of the conveyor belt are located at 1/3 height of vertical roll.
2.The distance between the vertical roll of belt sway switch and the normal position of conveyor belt should be 50 ~ 100 mm.
3.The quantity of belt sway switch ought to be determined according to the length of the conveyor, types and arrangement. Commonly it is located on the conveyor head, tail, convex segment, concave segment and the middle position.(Note: when the conveyor is longer, a pair of belt sway switch can be located every 30 ~ 35 m.)
4.Belt sway switch connects the conveyor middle frame through the mounting bracket, switch bracket will be welded with conveyor frame after the installing completion of the conveyor, and belt sway switch shall be bolted in the bracket.
