As we know, the condition of the belt conveyor is essential to the whole equipment and workers’ safety. Therefore, It is significant to make clear that how to make the belt conveyor protection device run stably and reliably in producing process, so that the belt sway switch make sense and protect workers’ safety. It’s a normal problem that conveyor belt slipping during the working process, which is extremely to cause failure such as conveyor belt breakage, even evolved person’s safety. So to install belt sway switch on belt conveyor is necessary. There are 2 common devices to prevent conveyor deviation and skidding: Belt Sway Switch and Slip switch. Here follows the explanation of belt sway switch, and to made users clear about belt sway switch, and sum up some precautions. Belt sway switch is a protection device which is used for detecting the degree of running deviation and alarm during the operation of belt conveyor, and also used to automatically emergency stop when the belt is run wrong seriously. Belt sway switch is installed on the two sides of belt conveyor according to a certain gap (about 20m), and its roller being squeezed by the edge of the conveyor belt that runs away from the center, when the roller is defected to a certain angle, it is turned on. The second belt sway switch has the complete function, it’s the international standard. Secondary belt sway switch should be installed on both sides of the conveyor with access to the place. To make sure that the installation place is convenient for maintenance staff to reach. The switch should be installed on the two sides of the belt conveyor, Vertical rollers should be perpendicular to the conveyor belt edge plane, and make the conveyor belt on both sides of the vertical roller height 1/3. The normal distance between the bet sway switch and the belt conveyor is better to be 50-100mm. The quantity of belt sway switch is according to conveyor’s length and model. Generally, they are installed in belt conveyor’s front back and the middle place. (plus: to set one belt sway switch in the middle every 30-35m.) The belt away switch should be connected with the conveyor intermediate frame through the mounting bracket, and the switching bracket shall be welded with the conveyor rack after the conveyor is installed, and the belt sway switch and it’s bracket are bolted with bolts. The belt sway switch is equipped with the most suitable for position control in all models to achieve a small pre-stroke (about 5 °) and the repetition accuracy of twice times the standard type, so that it is easy to do daily inspection of the action display, and can confirm the action status according to neon or led, when starting up, it can be easily checked and maintained.
The belt sway switch is a product which the function is to check belt conveyor’s abnormal state, and it is a safety protection device that it will alarm or emergency pause when belt conveyor is in abnormal state.
