The reference answers will be visible after responding; points are awarded by identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) It can destroy the oil film, increase wear, clog the oil passages and filters; generally, the oil turns black ； After filtration, if there is no significant improvement in color, the oil should be changed. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html Third Phase of HaiChuan’s Outstanding Management Members Selection Contest http://bbs.hcbbs.com/thread-1655902-1-1.html (Source: HaiChuan Chemical Forum)
It not only affects the performance of the oil, such as causing blockages in oil pipelines, nozzles, filters, etc., but it also increases equipment corrosion, damages the oil film, and leads to increased wear and carbon buildup.
It causes wear on the contact surfaces, leading to the deterioration of the lubricant
Babbitt metal that can damage bearings, leading to high bearing temperatures and excessive vibration
Mechanical impurities are substances that exist in lubricating oil in a suspended or precipitated state, are insoluble in gasoline or benzene, and can be filtered out. Mechanical impurities in lubricating oil are substances such as dust, sediment, and iron shavings that remain unremoved during oil processing, or that enter the oil from the outside environment during storage, transportation, and use. These substances not only affect the performance of oils, such as causing blockages in oil pipelines, nozzles, filters, etc., but they also increase equipment corrosion, damage the oil film, and lead to increased wear and carbon deposition. Therefore, mechanical impurities are absolutely not allowed in light oils, while the requirement for heavy oils is less strict, generally limited to between 0.005% and 0.1%.
Impurities not only affect the performance of oils, such as causing blockages in oil pipelines, nozzles, filters, etc., but they also increase equipment corrosion, damage the oil film, and lead to increased wear and carbon buildup.
Mechanical impurities in lubricating oil increase mechanical friction and wear, and can easily clog the oil passages in filters, leading to abnormal oil supply, unstable oil pressure, and even forced shutdown
Damage to the equipment, reducing cooling and lubrication effects
Mechanical impurities in the unit’s oil system will destroy the oil film, wear out equipment components, and may cause the parts of the governor to stick or fail. In electrical equipment, the presence of water allows mechanical impurities to significantly degrade the performance of the oil and of the equipment itself, posing a threat to the safe operation of the equipment.
