Description

Technical Field

[0001] This utility model relates to the field of oil seal technology, specifically to an oil seal with lip temperature monitoring function. Background Technology

[0002] Oil seals play a crucial sealing role in high-speed rotating machinery, and their lip temperature directly affects sealing performance and service life. Therefore, lip temperature monitoring is necessary. Traditional methods include infrared thermometry, temperature tagging, and inference. Infrared thermometry uses an infrared thermal imager or infrared thermometer to capture the infrared energy radiated from the oil seal lip surface and converts it into a temperature value. Its drawbacks include: it cannot directly measure the lip temperature, only the highest temperature on the outer surface of the oil seal; and it is easily affected by surface reflectivity, oil contamination, or lubricant. Temperature tagging involves coating the oil seal surface with a heat-sensitive coating or attaching temperature tags, and judging the temperature range by color changes. Its drawbacks include: it cannot monitor in real time, has low accuracy, and is only suitable for inspection after shutdown. Indirect inference involves measuring the inlet and outlet temperatures of the lubricating oil to estimate the lip temperature. Its drawbacks include: it cannot monitor online in real time, affecting the continuity of equipment operation; and it may interfere with the sealing performance of the oil seal. In summary, current methods cannot monitor oil seal lip temperature changes in real time under dynamic operating conditions, and improvements are urgently needed. Utility Model Content
