Assessing the Quality of Lubricating Oil for Centrifugal Fire and Smoke Exhaust Fans

Prolonged use of centrifugal fire and smoke exhaust fans can cause parts within the unit to wear out and become clogged, making operation difficult. While lubricating oil is essential, not all types of lubricating oil perform effectively, and improper use can be harmful. 1. Ensure proper lubrication of the centrifugal fire and smoke exhaust fan. ① Insufficient lubrication can lead to inadequate lubrication. ② Excessive grease, excessive agitation, or high temperatures can cause oil separation, decomposition, and leakage. 2. Check for excessive hard impurities in the grease. To check, take a small amount of grease with your finger and squeeze it. Judge the condition based on the texture. 3. Check whether the grease in the centrifugal fire smoke exhaust fan has deteriorated due to oxidation. ① In this case, the grease will turn black or become thick, and a hard film will form on the surface. ② If the grease has deteriorated due to oxidation, it can be distinguished by its appearance. Careful attention must be paid to the use of lubricants in centrifugal fire smoke exhaust fans. Lubricants deteriorate when they react with impurities in the air; if there are changes in color or odor, they must be replaced with new products in a timely manner.
