通过对SGW620/40T、SGD420/22、SGB620/55三种型号的刮板输送机因机械故障造成电机烧毁事故的实例分析,说明了润滑系统、液力耦合系统、电机振动、过负荷、减速器系统、输送机电动机安装与机械维护等机械故障对刮板输送机电动机运行的影响。指出了预防这些因素引起刮板输送机电动机烧毁事故发生的相关技术措施,提供了一些机械技术角度的现场维护、保养刮板输送机电动机的经验。
Through the example analysis of the motor burned accident caused by the mechanical failure of SGW620 / 40T, SGD420 / 22 and SGB620 / 55 scraper conveyors, the lubrication system, hydraulic coupling system, motor vibration, overload, Impact of System, Conveyor Motor Installation and Mechanical Maintenance on Motor Scraper Conveyor Operation. It points out some technical measures to prevent these factors from causing the burnt-down accident of the scraper conveyor motor, and provides some experience of on-site maintenance and maintenance of the scraper conveyor motor from a mechanical and technical point of view.
