Conveyor belt tensioning force shortage will be easy to slip, but the canvas creep elongation caused by the tension force is reduced, turtles characteristic skeleton material, and the type skeleton material. Here, we want to discuss The estimation of material in in the working section modulus, elongation at specified load on the conveyor belt or influence. We tend to like the constant load elongation test EP canvas and NN canvas, here also have a misunderstanding, cotton fiber is assumed constant load elongation is small, the conveyor belt during no-load start-up stress conditions, cotton Lun than polyester deformation is small, but the conveyor belt loaded, in full load, a graph characteristics between cotton fibers and polyester fibers, cotton fiber elongation than polyester, apparently the elongation of the material, means Tension, improve speed, also means easy to slip. Therefore, the conveying belt at startup, especially after slipping full parking start again, start the load is too large, the NN conveyor belt slippage can To be much larger than the EP canvas. Therefore only the assessment materials initial deformation is not enough, more important is the material under deformation before and after the size, which is called the dimension stability. Fiber materials include another performance, we called the relaxation, if we give fibers applied a predictable tension, keeping constant length, this and V with stress is similar, but after a certain time, the material should be Power is gradually reduced, in essence, and the material creep elongation is similar. Therefore the NN conveyor belt more prone to predict the tension, caused by skidding. To solve the conveying belt, but must have a good mechanical condition, timely repair tensioning, select the skeleton material suitable is the only viable method. Once the conveyor belt running long, inevitably The conveying belt. Slip is the curve extension and skeleton materials in work zones in strong gentle Chengdu related. Cotton fiber canvas in the working section, curve is too flat, the increase of load, resulting in elongation increase, and Zhang Liti High Co., eventually lead to slip. The performance of EP canvas is far better than the cotton fiber canvas. | |||
