【Q&A Question 221】August 9, 2017: What is the function of the turbine oil seal ring? The reference answer can be seen after responding; points will be awarded for identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) The function of the oil seal ring is to prevent or reduce the leakage of lubricating oil along the shaft from within the bearing housing toward the cylinder side. The turbine oil seal ring is generally horizontal in shape; its upper and lower halves are installed in the grooves located at the upper and lower parts of the bearing housing, where they are also axially positioned. Oil seal teeth are embedded at the part on its inner ring that matches the shaft; together with the oil baffle on the shaft, they prevent lubricant from leaking out. Several oil drainage holes are provided between the oil seal teeth of the lower oil seal ring, to direct the trapped oil into the bearing housing. After 7 days of daily activities, it shuts down and shows the answers automatically. (2017-8-14) Scoring criteria: Errors result in 2 Wealth points as a participation reward; *incomplete* answers earn 3–8 points. Correct answers with detailed explanations grant 10 Wealth points, while answers that are correct but lack sufficient details yield 15–20 Wealth points. Please score according to these criteria. Note: If there are editing records after answering, only points will be awarded to those who participated. For continuous malicious spamming, 2 points will be deducted each time, with no upper limit. Pure numbers, pure emojis, or random letters that have nothing to do with the answer are all considered malicious spamming; points will start to be deducted after three warnings. 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 Petrochemical Zone – “Creative Ideas for Energy Savings” campaign (the second phase is in full swing) http://bbs.hcbbs.com/thread-1666758-1-1.html (Source: Haichuan Chemical Industry Forum)
Oil seals are primarily used to prevent the lubricating oil inside the bearing housing from leaking outside through the shaft.

The function of the oil seal ring is to prevent or reduce the leakage of lubricating oil along the shaft from within the bearing housing toward the cylinder side. Turbine oil seal rings are generally horizontally split, with the upper and lower halves being installed in the grooves at the upper and lower parts of the bearing housing respectively and axially positioned. Oil seal teeth are embedded at the part on its inner ring that matches the shaft; together with the oil baffle on the shaft, they prevent lubricant from leaking out. Several oil drain holes are provided between the oil seal teeth of the lower oil seal ring to guide the trapped oil into the bearing housing.
