1.概述 我厂LN2000烧结风机及配套电机是从英国引进的,预测它的劣化趋势对组织烧结生产至关重要。几年来的经验告诉我们,风机的主要故障可通过它的振动信息进行检测,造成风机振动的原因主要有:①风机由于叶片磨损不均匀而失衡;②轴瓦由于冲击或磨损而与轴的配合间隙增大或损伤;电机在运行中产生位移而与风轮的同轴度偏差增大。风机振动如果发展严重,轻者将轴瓦损坏使振动进一步加剧,重者造成机毁人亡。 1. Overview Our LN2000 sintering fan and its associated motors are imported from the UK. It is predicted that the deterioration trend of LN2000 will be crucial to the organization of sintering production. Years of experience tells us that the main fan failure can be detected by its vibration information, resulting in fan vibration are mainly due to: ① fan imbalance due to blade wear imbalance; ② Bush due to impact or wear with the shaft with the gap Increase or damage; motor displacement in the operation of the coaxial with the wind turbine deviation increases. If the development of fan vibration serious, the light of the bearing bush damage to further aggravate the vibration, resulting in heavy machine crash.
