PRODUCT FUNCTION
Application case series
Case study on abnormal wear detection of bearings in finned air coolers
Due to the abnormal increase in vibration of the entire frame of the finned air cooler, it was diagnosed through iron powder concentration measurement that the A-side bearing had worn out. Fin type air coolers generally rotate at low speeds and experience significant pressure fluctuations on one side of the blades, making it difficult to detect anomalies using vibration methods in many situations. However, when combined with an iron powder concentration meter, it can effectively detect anomalies.
Criteria for determining the concentration of iron powder in lubricating grease
Based on the trend management of iron powder concentration and the accumulation of data, benchmark values that are relatively applicable to various equipment can be summarized
| SDM-72 Judgment Criteria | |
| Normal value | Below 0.05% |
| Attention value | 0.05~0.1% |
| outlier | More than 0.1% |
