【摘要】 旋转机械转轴径向碰摩是机组启动和正常运行中振动突然增大的主要故障之—,碰摩是一复杂的过程,大部分情况下,它为不对中、不平衡等故障的并发故障,从时域波形、一维频谱、轴心进动等多方面对其识别与诊断,并结合实例阐述其判断方法和诊断处理。更多还原

【Abstract】 The axial radial friction of rotating mechanism is one of the main fault when the vibration increases suddenly of the unit starting up or running normally. The fault is a complicated process, in most part of condition, it is the combining fault of misalignment and imbalance. We can identify and diagnose it from the wave of time, the spectrum, the axes eddy, and gave some examples to elaborate the distinguishable method and the diagnostic treatment.更多还原
