输送带.滚筒摩擦试验

[中文适用范围]： 本文件规定了一种测试方法，以确定传送带在给定张力下保持静止时，与旋转的从动钢滚筒表面接触时产生热火焰或辉光的倾向。 它描述了改变传送带张力的方法。 注：对于含有钢筋的输送带，由于输送带不能满足 7.2 的要求，因此可能无法完全进行该试验。 在这种情况下，可能需要根据 7.3 提前终止。 [外文原描述]： ISO 20238:2018 specifies a method of testing to determine the propensity of a conveyor belt to generate heat flame or glow when held stationary, under a given tension, in surface contact around a rotating driven steel drum. ISO 20238:2018 describes means of varying the conveyor belt tension. NOTE For conveyor belts containing steel reinforcement, it may not be possible to conduct this test in full due to the inability of the conveyor belt to comply with the requirements of 7.2. In this case, premature termination according to 7.3 can be necessary.
