Overhung Cooler Fan by Phase Analysis

Phase analysis is a key tool in checking the health of machines by looking at their vibrations. It measures how the timing of vibration signals line up with each other, usually from different parts of a machine. This helps find problems like parts not lining up right, balance issues, parts being loose, or gear problems.

Report of Smoke Exhaust Fans’ Vibration Measurement

Vibration measurement is a technique employed to identify and assess the magnitude of vibration in machinery or mechanical systems. It is an important technique in predictive maintenance and can help diagnose faults, especially in the early stages.

Structural Looseness in the System

Structural rigidity in the system plays a pivotal role in controlling vibrations. Once you have structural looseness, it starts dodging you with an unbalanced case and you start wasting your time in checking other things...

Sensor Reliability Impact on Predictive Maintenance Program Costs

Accelerometers with lower mean time between failures (MTBF) values result in higher costs for permanently installed vibration sensor applications - as much as $60 per vibration sensor. By taking the MTBF and manufacturing quality into account when making an accelerometer purchase, you can achieve lower overall program costs.

Data Quality Over Quantity

Seemingly, one advantage is gathering data at a vastly improved rate. Rather than a single reading every quarter, data can now be captured multiple times every hour. The advantages are obvious: much greater visibility on developing faults and a trail to follow to track existing known issues.
