Predictive Maintenance & Fault Diagnosis

 ABOUTUS


Bearings, gears and rotating shafts announce their failure in vibration long before they announce it in downtime. A handheld vibration meter, read on a schedule, is the cheapest early-warning system a maintenance team can own.

Machines Vibrate Differently Before They Break​

An imbalanced fan, a misaligned coupling and a worn bearing each leave a distinct signature in a vibration reading — and each signature typically shows up weeks or months before the fault becomes audible, visible, or catastrophic. Predictive maintenance is simply the discipline of taking that reading regularly enough to see the trend before it becomes a breakdown.
Aihua's vibration meters cover this full picture — from routine rounds on plant equipment to precision fault-finding, and the occupational and environmental vibration checks that go alongside them.

Bearing and gear-mesh defects generate energy well above running speed — acceleration and spectrum analysis catch them first

                                       Setting Up a Vibration Monitoring Route

  • true
       Step 1 Define the Route


    List every critical asset, and a consistent measurement point on each — the same location and orientation every time.

  • true
        Step 2 Baseline


    Take a first reading while the machine is known to be healthy; this is what every later reading gets compared against.
  • truetrue
                Step 3 Re-Measure & Trend

    Repeat on a fixed interval, switching parameter as needed, and watch for a rising trend rather than reacting to one reading.
  • truetrue
        Step 4 Diagnose & Schedule

    Once a trend is confirmed, use spectrum analysis to identify the likely fault and schedule the repair before it becomes a failure.

Four Vibration Checks Around Every Piece of Rotating Equipment

Condition monitoring on the machine itself is only part of the picture — the people and environment around it need checking too.

                                                    Common Questions About Vibration-Based Predictive Maintenance

  • 1. What's the difference between YT3001A and YT3001B?

  • 2. Which parameter should I trust — acceleration, velocity or displacement?

  • 3. Do I need a hand-arm vibration meter if I'm only monitoring machinery condition?
