厂家浅谈离心风机的故障维修技巧

2018-12-24 14:55:17 常州市星火铝艺制品有限公司 阅读

离心风机传动部位磨损是常出现的设备问题,其中包括抽风机轴承位、轴承室磨损、鼓风机轴,轴承位磨损等。针对离心风机上述故障,传统维修方法有堆焊、热喷涂、电刷渡等,补焊高温产生的热应力无法完全消除,易造成材质损伤,导致部件出现弯曲或断裂;而电刷镀受涂层厚度限制,容易剥落,且以上两种方法都是用金属修复金属,无法改变硬对硬的配合关系,在各力综合作用下,仍会造成包胶滚筒的再次磨损。采用高分子复合材料的修复方法,具有粘着力,优异的抗压强度等综合性能,可免拆卸免机加工。既无补焊热应力影响,修复厚度也不受限制,同时产品所具有的金属材料不具备的退让性,可吸收设备的冲击震动,避免再次磨损的可能。

The wear of transmission parts of centrifugal fans is a common equipment problem, which includes the wear of bearing position, bearing chamber, blower shaft, bearing position and so on. In view of the above faults of centrifugal fan, traditional maintenance methods include surfacing, thermal spraying and brush ferry, etc. The thermal stress caused by high temperature repair welding can not be completely eliminated, which can easily cause material damage and lead to bending or fracture of components; while brush plating is limited by coating thickness and easy to peel off, and the above two methods are metal repair, which can not change the hard-to-hard matching relationship. Under the combined action of force, the rubber-coated drum will still be worn again. The repairing method of polymer composites has comprehensive properties such as adhesion, excellent compressive strength and so on. It can be disassembled and machined free. There is no effect of thermal stress in repairing welding, and the thickness of repairing is not limited. At the same time, the metal material of the product does not have the retreat ability, which can absorb the shock and vibration of the equipment and avoid the possibility of wear again.
