【Q&A Question 207】August 1, 2018: Briefly explain why lubricant needs to be replaced regularly After being used for a certain period of time, the quality of the lubricating oil is affected by various factors, which requires its regular replacement: 1. Metal shavings worn off from the friction surfaces due to wear and tear ； 2. Dust and other hard particles brought in by air ； 3. Molding sand that was not carefully removed from the casting ； 4. The paint layer on the components has peeled off ； 5. Moisture is generated in the lubricant during the cooling process, causing the oil to deteriorate ； 6. The temperature of the lubricating oil and other factors in circulating lubrication cause its lubricating performance to gradually decline. The aforementioned debris easily forms an abrasive paste-like substance in the lubricant, contaminating it and significantly accelerating the wear of the machine’s friction surfaces. Therefore, if the lubricating oil in the machine deteriorates to the levels specified below over time, it should be replaced with fresh oil. If no testing equipment is available to conduct such checks, the oil should be changed every 2,000 to 3,000 hours, and the oil supply equipment as well as all lubrication points should be thoroughly cleaned. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

1) The friction surface becomes contaminated with impurities due to wear. 2) Dust and other hard particles brought in by air can form sludge. 3) The temperature and other factors associated with the cyclic lubrication process cause the lubricating properties of the oil to gradually decline

Answer: After being used for a certain period of time, the quality of the lubricating oil is affected by various factors, which requires it to be replaced regularly: 1. Metal shavings resulting from wear on the friction surfaces； 2. Dust and other hard particles brought in by air ； 3. Molding sand that was not carefully removed from the casting ； 4. The paint layer on the components has peeled off ； 5. Moisture is generated in the lubricant during the cooling process, causing the oil to deteriorate ； 6. The temperature of the lubricating oil and other factors in circulating lubrication cause its lubricating performance to gradually decline. The aforementioned debris easily forms an abrasive paste-like substance in the lubricant, contaminating it and significantly accelerating the wear of the machine’s friction surfaces. Therefore, if the lubricating oil in the machine deteriorates to the levels specified below over time, it should be replaced with fresh oil.
