制动片磨损率的变化影响到整个带式输送机鼓式制动器制动的安全,采用试验的方法开展研究。通过CFT-Ⅰ材料表面综合测试仪分析了制动压力和制动速度对磨损率的影响,并用扫描电镜对摩擦试样的表面情况进行观察分析。结果表明:该制动片适宜用于制动压力大的工况;相比较制动压力,制动速度的影响较大;磨损率受到时间和温度的影响都较大。 The change of the wear rate of the brake pads affects the braking of the entire belt conveyor drum brake. The test method is used to carry out the research. The influence of braking pressure and braking speed on the wear rate was analyzed by CFT-Ⅰ material surface tester, and the surface of the friction specimen was observed and analyzed by scanning electron microscope. The results show that the brake lining is suitable for the conditions of high braking pressure, the braking speed is more affected by the braking pressure, and the wear rate is greatly affected by the time and temperature.
