Vibration Analysis for beginners 1 (Predictive Maintenance and vibration explanation. How it works?)
https://adash.com/
In this video we simply explain what Vibration Diagnostics or Vibration Analysis is, how it works and what is good for.
You've probably heard these terms before: Predictive Maintenance, Machine Condition Monitoring and also Vibration Analysis - What are these terms?
Vibration analysis is a major part of condition monitoring programs. Vibration Analysis tools are here to help us to predict machine failures. When condition monitoring is applied and the machines are chacked regularly, machine faults can be discovered at en early stage and appropriate action can be taken. By doing so you can avoid replacing parts which are still in good condition.
Running machines generate vibrations, which contain a lot of information about their condition. A vibration meter or analyzer is used to measure this vibration. The sensor needs to be mounted on an appropriate point on the machine (e.g. bearing housing). The instrument measures the vibration signal, tells you the severity of the vibrations and also possible machine faults. The most frequent faults are bearings faults, unbalance, misalignment and looseness.
Predictive maintenance -the machine should be repaired when it is really needed. The right moment is when failure is near – or in other words when the fault starts affecting the machine, but it is still safe to keep the machine running until the time for repair suits the company best (for example during a planned downtime). And predictive maintenance can recognize this moment.
To 'see' a motor’s vibrations we’ve got some excellent helpers today: an acceleration sensor and vibration meter or analyzer.
While performing Vibration Diagnostics we want to distinguish two important things which we get from the signal: overall machine condition and bearing condition, (as each of them is diagnosed from different parts of the vibration signal.)
Vibration Diagnostics is more sophisticated of course and later on you will find out that you need to separate more vibration sources which are generated by a running machine (for example loose foundation bolts, unbalance, misalignment, fan blade faults, gear mesh faults and many more.) But for now, let's just talk about those two basic things for an easier explanation.
Machine Condition Monitoring - there are more methods for evaluating a machine's condition and its faults. Besides Vibration Diagnostics you may have heard about Ultrasonic detection, Thermography, or others Non-destructive Testing. All these methods are part of Machine Condition Monitoring. Each method has its pros and cons; it is up to your maintenance program which methods you select (or combine them) and which methods are the best for your particular machines. However, during the last few decades it has been found and proven that Vibration Diagnostics is the most efficient and reliable method for most rotating machinery.
