水环真空泵轴磨损原因,可以总结为以下几点:

1.金属正常疲劳磨损,这是金属本身固有的特性

2.是配合关系问题,零件在加工过程中无论加工的精度有多么高,永远无法达到部件配合面100%的配合,配合部位受力面小也是导致金属疲劳磨损的根本原因之一

3.安装问题,安装过程中不能很好的控制轴承的安装位置或者无法有效控制轴承的游隙,导致轴承运行过程中无法处于一个最佳状态,进而运行阻力增大,温度升高,将扭矩更多的作用于配合面处,导致轴承内圈和轴表面发生相对运动,造成轴的磨损

4.运行保养,包括轴承的润滑不佳,冷却系统堵塞造成运行温度过高,紧固装置的松动等

水环真空泵轴磨损修复案例:某企业配备两台水环式真空泵传动侧轴承位多次出现磨损,设备数据如下:轴承型号:352956X2/P5,轴直径:280m, 轴承内径:280mm,轴修复宽度:130mm,转速:400r/min,轴承厚度:134mm,工装定位面尺寸: 315.00mm,工装修复面尺寸:280. 14mm。水环真空泵轴磨损修复可以选择索雷碳纳米聚合物材料修复,该材料综合力学性能优于金属,其具备优异的“退让性”,不具备金属疲劳磨损特性和塑性变形性,因此长期使用过程中不会产生疲劳磨损、断裂的情况,所以保证设备长期运行过程中,静配合面之间不会因为疲劳磨损而产生间隙
