输送机托辊的质量辨别
发布者:lizhongssd 发布时间:2019/1/9

托辊是带式输送机的重要组成部分,其品种多、数量大。它占带式输送机总成本的35%,接受70%以上的阻力,因而托辊的质量尤为重要。

The idler is an important part of belt conveyor, which has many varieties and large quantities。 It accounts for 35% of the total cost of belt conveyor and receives more than 70% resistance, so the quality of idler is particularly important。

托辊的作用是支撑输送带和物料的分量。托辊的操作有必要灵敏牢靠。下降输送带与托辊之间的冲突对输送带的使用寿命起着关键作用,其占输送带总成本的25%以上。

The role of supporting rollers is to support the weight of conveyor belts and materials. It is necessary to operate the idler sensitively and reliably. Decreasing the conflict between conveyor belt and idler plays a key role in the service life of conveyor belt, which accounts for more than 25% of the total cost of conveyor belt.

托辊是带式输送机的一个小部件,其结构不杂乱,但出产高质量托辊并不简单。判别托辊质量的规范有:托辊径向跳动;托辊柔性;轴向跳动。托辊径向跳动对带式输送机的影响:在国家规定的跳动范围内,能确保带式输送机平稳运转。不然,会使带式输送机的皮带发作共振跳脱,形成物料喷溅,污染环境,且带速越高,径向跳脱效益越小。托辊柔性对带式输送机的影响:在带式输送机运转过程中,托辊柔性是非常重要的。假如托辊的柔性欠好,滚动阻力系数高,整个带式输送机体系将不得不支付更多的动力,耗费更多的电力,有时会形成皮带撕裂,电机焚毁,乃至更严峻。引起火灾。

The idler is a small part of belt conveyor. Its structure is not disorderly, but it is not easy to produce high quality idlers. The criteria for judging the quality of idlers are: radial runout of idlers; flexibility of idlers; and axial runout. The influence of radial runout of idler on belt conveyor: within the runout range prescribed by the state, the belt conveyor can run smoothly. Otherwise, it will make the belt of belt conveyor resonance jump, forming material splash, polluting the environment, and the higher the belt speed, the smaller the benefit of radial jump. The influence of idler flexibility on belt conveyor: In the process of belt conveyor operation, idler flexibility is very important. If the rollers are not flexible enough and the rolling resistance coefficient is high, the whole belt conveyor system will have to pay more power and consume more power. Sometimes belt tearing, motor burning, and even more severe. Cause fire.
