Operating Principle:
The Gland Ring is composed of a rubber O-ring and a Teflon ring. The O-ring applies force, and the Gland Ring serves as a double-acting piston seal. It generates a high initial contact stress on the sealing surface due to its own deformation, preventing the leakage of pressureless fluids. During the operation of the hydraulic cylinder, the pressure fluid passes through the elastic deformation of the O-shaped seal, greatly squeezing the square seal ring, causing it to tightly adhere to the sealing surface. This results in an additional contact stress that increases with the pressure of the pressure fluid, working in conjunction with the initial contact stress to prevent the leakage of pressure fluids.
Application Range:
Hydraulic reciprocating motion environment. Properly used, it excels in piston rod sealing applications under high, medium, low pressure, heavy loads, and high-frequency conditions. The PSI type is particularly suitable for long stroke applications and can accommodate larger piston rod clearances in a wide range of fluids and high-temperature environments. For example, it is used in bulldozers, excavators, forging presses, ceramic brick presses, rolling mills, servo valves, and other machine tools.
Features:
1. A dynamic seal with superior low friction and high-speed performance, boasting chemical resistance superior to all other thermoplastic and elastomeric materials. It is nearly compatible with all liquid materials, and the side groove ensures reinforced pressure load on the O-ring under any working condition.
2. The interior static O-ring components feature low deformation characteristics.
3. No slippery motion tendency.
4. Space-saving construction with simple grooved design.
5. High compatibility, nearly compatible with all fluids (when the correct O-ring material is selected)
6. High anti-extrusion capability.
7. Excellent high-temperature resistance performance.
