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.) ) Note: For questions of the type \"one question per day,\" if a person replies continuously for a month, that is, posts more than 30 times, their score will be assigned as 2 points, which is the lowest possible score. Click once to reply; if multiple replies are made, points will be awarded as appropriate, as deleting posts is also a waste of time. The guide ring, also known as the support ring, is generally required on the pistons of oil-free lubrication compressors. Its function is to bear the weight of the piston components as well as lateral forces arising from other reasons, ensuring the linear movement of the piston, improving the sealing performance, and also preventing direct contact between the piston and the cylinder barrel, thereby avoiding damage to the cylinder walls. Scoring criteria: 2 Wealth points for incorrect attempts; 3–8 points for *incomplete* answers. 10 Wealth points for correct answers, provided along with a detailed explanation; 15–20 Wealth points if the answer is correct but lacks sufficient details. Please score according to these criteria. Note: If there are editing records after answering, only 1 Wealth point will be given to the participant. For continuous malicious spamming, 2 Wealth 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 started) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have started) 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
Prevents direct contact between the piston and the cylinder wall, thereby avoiding wear, and also serves as a guide
A guide ring, also known as a support ring, is a component used on the piston or piston rod of hydraulic cylinders or pneumatic cylinders to support the movement of the piston or piston rod. It prevents the piston or piston rod from making direct contact and experiencing friction with the cylinder body during movement, thereby protecting both the cylinder body and the piston or piston rod from damage. The commonly used material for guide rings is polyoxymethylene (POM).
The guide ring serves to guide and position, as well as to provide support
The function of the guide ring is to bear the weight of the piston components, improve the coaxiality of the piston’s linear motion, prevent direct contact between the piston and the cylinder barrel, and reduce wear on the cylinder and piston rings.
Bear the weight of the piston components. Improve the coaxiality of the piston’s linear motion. Prevent direct contact between the piston and the cylinder. Reduce wear between the piston rings and the cylinder.

It serves to guide, support, and protect the piston, while also regulating the gas flow rate and pressure experienced by the piston rings
