In rotating machinery, comparing with baseline data becomes important. If the operation is under the same conditions as the baseline data, only changes in environmental temperature should be considered, and by comparing values after subtracting the environmental temperature, the temperature changes of the equipment can be confirmed. In cases where there are temperature changes, such as an increase in temperature at the motor CP side bearing, it can be inferred that some change has occurred in the equipment, indicating a possibility of malfunction. 【Relative Judgment Criteria】 * It is recommended to manage according to the following criteria based on empirical rules. ■ Temperature Change Values / Corresponding Actions ・Less than 10℃ / Judged as normal ・10℃ or more but less than 40℃ / Strengthened monitoring, actions such as repairs ・40℃ or more / Actions for repairs The temperature change value is calculated using the following formula: (Baseline temperature - Baseline environmental temperature) - (Measured temperature - Measured environmental temperature) * For more details, please feel free to download the PDF or contact us.

In the diagnosis of rotating machinery, measurements are conducted on the "entire motor," "bearing section," and "pump bearing section." The measurement methods include "vibration diagnosis" and "thermography diagnosis," each of which has its strengths and weaknesses depending on the diagnostic area. "Vibration diagnosis" excels in diagnosing issues such as bearing problems, misalignment, and imbalance, while "thermography diagnosis" detects faults from a temperature perspective, particularly in the stator winding section and terminal section, and is proficient in diagnosing lubrication conditions. By leveraging and complementing the strengths of each technique, we contribute to improving the accuracy of equipment diagnosis. 【Checkpoints】 ■ Entire motor - Frame temperature - Heat generation in the terminal box - Overall temperature distribution ■ Bearing section - Temperature of the bearing section - Temperature distribution of the bearing section ■ Pump bearing section - Temperature of the bearing section of the coupled rotating machinery - Temperature distribution of the bearing section *For more details, please feel free to download the PDF or contact us.

The traditional inspection method (sounding method) takes time and costs money, and also involves the hassle of setting up scaffolding. The diagnostic reports, which mainly consist of text and numbers, were difficult for people without specialized knowledge to understand. The structural diagnosis using thermography (infrared method), which has been gaining attention in recent years, offers a cost-effective and hassle-free solution, providing visually understandable diagnostic results. There is no need to set up scaffolding, ensuring the safety of the workers. Since it does not involve applying impact or chemicals, it is also beneficial for the preservation of the inspected properties. In Japan, non-destructive testing using infrared camera imaging is still not widely recognized. In contrast, overseas, qualification systems have already been established, and the training of technicians is progressing. Such technology is particularly needed in Japan, which is prone to disasters like earthquakes and typhoons. Dainichiseika is committed to the long-term promotion of this groundbreaking inspection method. *For more information, please download the catalog.*
