Vibration cause analysis
Thread Content
I once heard an experienced master say that high vertical vibration levels are usually caused by rotor imbalance, while high horizontal vibration levels are due to poor alignment. Is there any basis for this statement?
It seems like there’s no basis for it. I’m learning this too, hehe
Practical experience is also a valuable asset! I think there’s some truth to it.
It’s not only unfounded but also wrong, haha. I wonder if you have it mixed up.
I remember that: a high first harmonic frequency is caused by rotor imbalance, while a high second harmonic frequency is caused by poor alignment
\"Upstairs\" generally refers to the online vibration monitoring of large-scale units; it is the S8000 system used by Sinopec
Huh? Reversed? How did that come about?
I remember there were posts on the forum about status monitoring, with detailed explanations; the original poster can give it a search
The issue of vibration is quite complex; I’m just trying to provide a starting point for further discussion. There are also types of misalignment such as angular misalignment and parallel misalignment. The characteristic of angular misalignment is large axial vibration, while the characteristic of parallel misalignment is large radial vibration. The characteristic of dynamic imbalance should be large radial vibration.
There’s no basis to formulate a law
