What are the hazards of a disruption in the cooling water for hot oil pumps? 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.) ) Once the hot oil cooling water is interrupted, it becomes impossible to control the temperature rise of the pump; this can lead to a rapid increase in the temperature of the bearing housing in a short period of time. The seals heat up, causing the pump to leak oil. Over time, the bearings can overheat and get damaged, the lubricating oil can oxidize and deteriorate, the oil tank can become too hot to touch, and it may even lead to damage to the shafts and other components of the pump. Scoring criteria: 2 Wealth points for incorrect attempts; 3–8 points for *incomplete* answers. 10 Wealth points for correct answers, provided with detailed explanations; 15–20 Wealth points for correct answers with additional *insufficient* details. Please score according to these criteria. Note: If there are editing records after answering, only those who participated will be credited points. For continuous malicious spamming, 2 points will be deducted each time, with no upper limit. Pure numbers, pure emojis, or random letters unrelated to 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)
Once the cooling water supply is interrupted, it becomes impossible to control the temperature rise of the pump. In a short period of time, this can lead to a rapid increase in the temperature of the bearing oil tank; the seals may overheat, causing the pump to leak oil. Over time, the bearings can overheat and get damaged, the lubricating oil can oxidize and deteriorate, the oil tanks can become extremely hot, and this may even result in the shaft seizing or the pump tripping, thereby causing severe damage to the internal components of the pump.

Seal failure, shaft seizure; high temperature caused damage to the O-ring

The temperature of the bearing oil tank rises rapidly; the seals heat up, causing the pump to leak oil. Over time, this can lead to overheating of the bearings and their damage, as well as oxidation and deterioration of the lubricating oil. The oil tank becomes extremely hot, and in severe cases, it can even cause the shafts to stick together
It can cause a rapid rise in temperature within a very short period of time; the enclosed space generates heat, which in turn affects the pump
Reduce the temperature of the bearings； Carries away the small amount of liquid that leaks from the shaft seal, and dissipates the friction heat ； Reduce the temperature of the stuffing box, improve the operating conditions of the mechanical seal, and extend its service life ； Cooling pump support, to prevent misalignment of the pump and motor due to thermal expansion ；
