Bring in the Pros When You Want Reliable Laser Vibration Analysis
What exactly is laser vibration analysis? Properly speaking, vibration exist to varying degrees in all rotating or reciprocating (up and down movement) equipment. It is undesirable on account of related noise, discomfort, wastage of energy and quicker wear and tear in moving parts, leading to shortened life of components and parts. There will always be a degree of vibration when moving parts are involved. Perhaps you may have often felt some juddering in your office elevator or escalator inside the mall as well as the cause is vibration. Since it will be present in practically each item with moving parts, it will be interesting to know why it takes place and what to do about it.
Vibration or the oscillatory movement of parts in a miniscule scale, in any rotating or oscillating or reciprocating machinery due to inherent ‘imbalances’ existing at one or more points. By imbalance what exactly is meant is that the mass is not distributed equally in all directions. Rotating shafts may have eccentricity, which means the axis of rotation is not perfectly along the axis of weight distribution. There is no reason to get perplexed with all this, because technology is there to help you in detecting the causes, at what exact points these aberrations lie, what exactly is their extent and how much mass needs to be added or taken out to correct the problem. Thus, vibration analysis.
Vibration analysis can be done by several types of equipment, but one of the most modern and simplest to handle is the laser vibration analyzer. This directs a highly focused and low energy laser beam at the potential trouble spot inside the rotating motor or other machinery and depending on the shift in frequency of the reflections received, the frequency and mode of vibration as well as the mass imbalance is indicated. But all of this is actually much easier than it may sound at first. In fact many of you have actually seen such equipment in operation without realizing. Do you recall the mechanic telling you that your car need wheel balancing and you insisted on watching it? Don’t forget that additional weight was added at carefully calculated positions, okay? Now, you that’s it in a nutshell. Whatever there is to know about laser vibration analysis along with the hardware hinges on the specific task at hand. And just who’s to say one way or the other, whatever it’s all about in the final analysis, anyway?
