我厂为了贯彻“压力容器安全监察规则”,对碱性焊条进行400℃以上烘干,购进了8810型电热鼓风干燥箱。但在使用半年左右,风扇轴和电动机轴的联轴器就损坏了,按原样修复不久就又坏了。经分析其原因认为:主要是因烘箱是用薄钢板制成,刚度较差,在经400℃以上温度烘烤一段时间后,内部有所变形,这样就加大了轴与轴之间的不同心度,造成风叶 I plant in order to implement the “pressure vessel safety supervision rules”, alkaline electrode above 400 ℃ drying, purchased the 8810 electric blast oven. However, after about six months of use, the coupling of the fan shaft and the motor shaft was damaged, and the original repair was broken shortly afterwards. The analysis of the reasons that: mainly because the oven is made of thin steel plate, the stiffness is poor, after baking at a temperature above 400 ℃ for some time, the internal deformation, thus increasing the difference between the shaft and the shaft Heart, resulting in leaves
