Thermography

Many motor problems can be predicted. An infra-red Thermography spectral display is a snap shot in time, showing the disparity of temperatures exhibited throughout a motor. When seen in comparison with baseline displays the effect is even more dramatic.

Elevated temperatures can be the result of bearing faults, shaft misalignment, belt misalignment, loose or tight bearing fits, mechanical binding or overloaded motors. Even winding faults can sometimes be caught in the early stages of failure. Knowing the condition of a critical piece of equipment allows for scheduling of required maintenance, in many cases avoiding catastrophic failure at the most inopportune times.

Bradleys’ thermal imagers deliver high-resolution images so temperature differences can be seen, even very fine differences. This technology uses the previous image and captures a visible light image to provide enough detail for the results, helping to identify all components for repair. Our onsite thermography service and documentation ensures a complete quality system; while minimizing unscheduled down time.

Benefits:

  • Predictive Maintenance - Identify electrical and mechanical problems before they cause failure.
  • Industrial Maintenance - Determine if repairs have been performed successfully.
  • Quality Control - Examine prototypes and refine thermal management designs.
  • Process Monitoring - Real-time observation to ensure efficient and safe operation.

Vibration Analysis:

At some time during a motor's life, it is likely to experience high vibration levels. What's behind this maintenance phenomenon? The cause may be an electromagnetic or mechanical imbalance, loose components, rubbing parts, bearing failure, or resonance.

When a problem occurs, it is critical to quickly identify the source and take corrective action. Using Bradleys’ latest vibration analysis diagnostic techniques can save you money and downtime. Bradleys’ CSI-2130 device is a portable, route-based instrument used for collecting vibration data on rotating machinery. It reduces collection time by more than 50 percent, compared with similar devices. This allows Bradleys to determine the severity of the stress level of bearing or gear wear on your motor. The data is recorded from each machine and uploaded on the software, providing quick recognition of change in the vibration pattern, as an indicator of deterioration. Corrective actions are then taken.

Benefits:

  • Detect Early Signs of Gear and Bearing Wear - By detecting imbalance or misalignment, further wear and tear can be prevented.
  • Frequency Range - A full spectrum of signal measurement.
  • Increase in Motor Health & Operation - Diagnostic tools adapt to varying turning speeds; offering information on developing field problems.
