Cooling tower fan blades with strain-based transducers.
Strain Gauges Improve Cooling Tower Fan Performance
Cooling towers are an integral part of geothermal power plants, as they help to cool the water used in the power generation process by circulating air using large fan blades.
However, the fan blades of cooling towers are subjected to high levels of stress and vibration, which can result in damage and failure over time. Hence, regular inspection and testing of these fan blades are crucial to avoid potential issues that could lead to costly downtime.
Test Case: Philippines Cooling Tower
In a recent case, Integrated Test & Measurement (ITM), a leading engineering solutions provider, was called upon to perform strain gauge testing on a composite cooling tower fan blade at a geothermal power plant located in Mount Apo, Philippines.
The goal of the testing was to measure the stresses on the fan blade and identify any potential issues before they resulted in costly downtime. Our team took a detailed approach to the task, and our methodology can serve as a blueprint for inspecting and testing fan blades in power plants.
The first step of the process was a thorough inspection of the fan blade and its surrounding structure. We identified key locations on the fan blade where stresses were likely to be highest and installed strain gauges at these points. The team also installed accelerometers to measure the vibration of the fan blade during operation.
Strain gauges are sensors that measure the strain or deformation of an object, while accelerometers measure the acceleration or vibration of an object. By installing these sensors, the ITM team was able to gather data on the performance of the fan blade during normal operation and during extreme wind conditions.

After collecting the necessary data, we analyzed it to identify any issues with the fan blade’s performance, such as excessive stress or vibration. The team discovered that the fan blade was experiencing high levels of stress at the root of the blade, likely caused by an imbalance in the blade. They also found that the fan blade’s vibration was higher than expected, indicating a problem with the bearings or the blade’s balance.
Based on this analysis, we recommended that the fan blade be balanced and that the bearings be inspected and replaced if necessary. Additionally, the team suggested reinforcing the fan blade’s root to distribute the stresses throughout the blade more evenly. Our team worked closely with the power plant’s maintenance team to implement these changes and perform follow-up testing to ensure that the fan blade was operating within the desired specifications.
Our attention to detail and comprehensive testing procedures allowed us to identify potential issues with the fan blade before they led to costly downtime. By utilizing strain gauges and accelerometers to measure the performance of the fan blade, the team was able to pinpoint specific areas of concern and make targeted recommendations to improve the blade’s performance. The collaboration with the power plant’s maintenance team ensured that the necessary changes were made promptly, and the follow-up testing confirmed that the fan blade was operating optimally.
Overall, this is a prime example of how ITM can assist in improving the performance and reliability of equipment in power plants. By leveraging our expertise and advanced testing methods, we can help power plants to identify potential issues and make informed decisions to prevent costly downtime.
Additionally, ITM’s involvement in this project highlights the importance of regular inspection and testing of equipment in power plants, as these proactive measures can help to avoid costly repairs and downtime in the long run.
To review, cooling tower fan blades are essential components in geothermal power plants, and their performance must be regularly monitored to ensure the optimal operation of the plant.
ITM’s use of strain gauges and accelerometers to measure the performance of the fan blade allowed us to identify potential issues and make targeted recommendations to improve its performance. By working closely with the power plant’s maintenance team, we were able to implement the necessary changes promptly, which helped to avoid costly downtime.
Why turn to ITM for Strain Gauge expertise?
