Material And Function Of Guide Ring

Guide ring, also known as the support ring, is a hydraulic cylinder or cylinder piston or piston rod on the support piston or piston rod movement parts, it can prevent the piston or piston rod in the process of movement and direct contact with the cylinder and friction, play a role in protecting the cylinder and piston or piston rod from being damaged.
Polyformaldehyde (POM) is commonly used as a guide ring. Phenolic plastic is a kind of hard and brittle thermosetting plastic, commonly known as bakelite powder. High mechanical strength, tough wear, stable size, corrosion resistance, excellent electrical insulation performance. Suitable for the production of electrical appliances, instruments insulation mechanism parts, can be used in hot and humid conditions formability 1. The formability is good, but the shrinkage and directivity are generally larger than ordinary plastics, and contain moisture volatiles. Should be preheated before forming, forming process should exhaust, not preheated should increase the mold temperature molding pressure.2. Mold temperature has a great impact on liquidity, generally more than 160 degrees, liquidity will rapidly decline.3. The hardening speed is generally slower than that of ordinary plastics, and the heat released during hardening is large. The internal temperature of large thick wall plastic parts is easy to be too high, and it is easy to have uneven hardening and overheating. Bakelite guide ring: mainly guiding function.

Guide sleeve FAI: Application condition: professional piston, supporting and guiding the piston, and dustproof. Use temperature: -60℃~+220℃ Material: PTFE, POM, PA.
How to install the guide ring on the piston:
How is the guide ring on the piston put on? Is it hot? How to install the inner diameter of the measuring guide ring less than the outer diameter of the piston groove?
What is the inside diameter of your guide ring? How many piston grooves? And what is the guide ring made of? And do your piston rings have openings? If the material of your guide ring is PTFE, and the difference is slightly larger, it is generally the use of hot loading, if the difference is particularly large, not only hot loading, but also with the fetal, otherwise it can not be installed
There are generally two types of compressor, one compressor support ring does not need to be heated. The other kind requires heating.
