【Q&A Question 215】August 03, 2017: What impact does a high exhaust temperature of the compressor have on it? 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.) ) A high exhaust temperature of the compressor has the following adverse effects on it: (1) It deteriorates the operating conditions of the cylinders, valves, and packing. ⑵The load on the cooling system increases, leading to higher water consumption. ⑶It deteriorates the lubrication conditions in the cylinders, causes the lubricating oil to degrade, and accelerates the wear of piston rings and gaskets. If the temperature exceeds the flash point of the lubricating oil, it can also lead to explosions in the compressor. ⑷Reduce the compressor’s exhaust volume to increase its power consumption. Scoring criteria: 2 wealth points for incorrect answers; 3–8 points for *incomplete* answers; 10 wealth points for correct answers accompanied by a detailed explanation; 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 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 no relation 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 Website)
1. It reduces the volumetric efficiency of the compressor and increases power consumption. 2. Overheating reduces the viscosity of the lubricating oil, causing unnecessary wear on bearings, cylinders, and piston rings; it can even lead to serious problems such as damaged bearing shells, shaft journals, and cracked cylinder walls. 3. It causes the refrigerant and lubricating oil to decompose upon contact with metals and other substances, resulting in the formation of carbon deposits and acids. 4. Excessive exhaust overheating can cause the piston to expand excessively and get stuck inside the cylinder, as well as leading to the destruction of the built-in motor in hermetic compressors. 5. Excessively high exhaust temperature can also affect the compressor’s lifespan, as the rate of chemical reactions increases with rising temperatures.

A high exhaust temperature in the press has the following adverse effects on it: (1) It deteriorates the operating conditions of the cylinders, valves, and packing. ⑵The load on the cooling system increases, leading to higher water consumption. ⑶It deteriorates the lubrication conditions in the cylinders, causes the lubricating oil to degrade, and accelerates the wear of piston rings and gaskets. If the temperature exceeds the flash point of the lubricating oil, it can also lead to explosions in the compressor. ⑷Reducing the compressor’s exhaust volume increases its power consumption.
Operating the equipment at high exhaust temperatures for an extended period will reduce its service life. High temperatures directly affect the lifespan of air compressor components and can even damage the compressor. When the system shuts down due to excessive temperature, it causes production interruptions and results in huge losses.
High exhaust temperature can cause carbon buildup in the valves. And it affects the lifespan of the valve. In severe cases, it can damage the valve
1. If the exhaust temperature is too high, the viscosity of the lubricating oil decreases, resulting in poor lubrication. 2. If the exhaust temperature is too high, it can also cause the lubricating oil to carbonize and clog; this ultimately affects the compressor, leading to its jamming and subsequent burnout of the motor.

1. High exhaust temperature: For compressors with oil lubrication, high exhaust temperatures can affect the viscosity of the lubricating oil in the cylinders, causing changes in its properties. This leads to poor lubrication effects and even a loss of the lubrication function. Moreover, the carbon deposits that accumulate over time due to high temperatures can pose a risk of combustion and explosion； 2. High exhaust temperature also affects the service life of the compressor’s vulnerable components, such as valves, packing, piston rings, and support rings ； 3. The exhaust temperature is high, and the materials in contact with the exhaust also need to be heat-resistant.
