通过对煤矿生产实践中YBSS低压系列输送机用隔爆型三相异步电动机异常振动的8个实例的分析,说明了该系列电动机安装不规范、转子故障、轴承磨损、电动机机壳刚度不够等4种因素引起的电动机运转中出现了异常振动和噪声故障。指出了预防这4种因素引起电动机故障发生的相关技术措施,提供了一些现场维护、保养YBSS隔爆型电动机的经验。
Through the analysis of 8 examples of abnormal vibration of flameproof three-phase induction motor used in YBSS low pressure series conveyor in coal mine production practice, it shows that this series of motors have irregular installation, rotor failure, bearing wear, insufficient rigidity of the motor casing 4 Abnormal vibrations and noises appear in motor operation caused by various factors. It points out the related technical measures to prevent the motor failure caused by these 4 factors and provides some experience in field maintenance and maintenance of YBSS flameproof motor.
