矿山的开采过程离不开机电设备的使用,倘若矿山机电设备在工作过程中出现故障,不仅会导致人员伤亡,还会对矿山企业的经济带来不可估计的损失。由于矿山机械设备往往是在非常恶劣的环境中工作,故障发生率很高,因此,为保证矿山企业的持续健康发展,做好机电设备的维修工作非常关键。本文对矿山机电设备产生故障的原因进行了总结,并分析了具体的诊断维修技术。 Mining process can not be separated from the use of mechanical and electrical equipment, if the mine mechanical and electrical equipment in the process of failure, not only will result in casualties, but also on the economic losses of mining enterprises with incalculable losses. As mining machinery and equipment are often working in very harsh environments, the incidence of failure is very high. Therefore, in order to ensure the sustained and healthy development of mining enterprises, it is crucial to do a good job in the maintenance of mechanical and electrical equipment. This paper summarizes the causes of the failure of mine mechanical and electrical equipment, and analyzes the specific diagnosis and maintenance techniques.
