Do you know the installation method of the Glea ring?

The Glaus ring is PTFE in English. It is a combination of PTFE NBR material rubber O ring and PTFE ring. The shaped rubber sealing ring provides sufficient closing force to compensate for the wear of the rectangular ring. The Glaus ring is suitable for two-way closure between the hydraulic cylinder hole and the piston.

　　The Glaus CircleEnglish is PTFE, is made of PTFE NBR material rubber O-ring and PTFE ring combination, shaped rubber sealing ring to provide enough tight closing force, compensation for the wear of rectangular ring, Glea ring is suitable for hydraulic cylinder between the hole and the piston is two-way closed.

Under special circumstances, the rubber elastomer nitrile rubber NBR uses fluorine adhesive FKM, which can be divided into hole Gram ring and shaft grid, but the effect is the same. According to its own deformation, high initial contact stress is generated on the sealing surface to prevent No pressure liquid leaks. When the hydraulic cylinder is working, the pressure liquid squeezes the square seal to a large extent through the elastic deformation of the O-ring and clings to the sealing surface, an additional contact stress, which increases as the pressure of the pressure liquid increases, is generated to prevent leakage of the pressure liquid together with the initial contact stress. The Gloire ring can be used for the design that both sides of the piston are under pressure. There are pressure guide grooves on both sides of the sliding ring, which can adapt to rapid pressure changes. So, how much do you know about the Gloire ring installation method?

Because GLEY is composed of a combination of hard PTFE and soft O-type, you will also be prompted to use the correct GLEY ring placement method during the process. Then, what is the correct GLEY ring installation method?

Xiao Bian recommends that you use special assembly tools. If PTFE needs to be twisted during assembly, it is recommended that you place it according to the following steps: However, twisting will affect the sealing performance. Please be careful at this time and do not act too violently.

Step 1: Apply system pressure oil before assembly and insert the back ring into the groove.

Step 2: Use your fingers or sealing ring installation tools to make the sliding ring heart-shaped. At this time, you must be careful not to move too hard.

Step 3: After assembling the slip ring into the groove, push it in the direction of its inner and outer surroundings and restore it to its original state.

Step 4: Insert the driven wheel several times to modify the deformation of the slip ring next week.

Reminder: It is recommended to use two piston guide rings for long forming cylinders, and one guide ring for short strokes under low radius loads. For special applications that require high temperature or chemical substances that require impedance, the piston seal is made of PTFE additives and Fluororubber materials, if the outer diameter is less than 40mm, it is recommended to use an open groove, the assembly tool must be a soft material, no sharp angles, and it is very important not to damage the Glees.
