The silicone seal - The performance of the sealing ring - Seals use dictionaries

the performance of the sealing ring and the use of the


sealing ring is silicone seal as used in the mechanical equipment is very much, but his specifications and function is very much also, today we go and see all kinds of silicone seal performance and USES what in the hell.


the silicone seal performance





the silicone seal have numerous advantages, the first is the heat performance is able to work under low temperature environment, the minimum can reach 100 degrees below zero, has the very good resistance to oxidation and ozone in the air performance, due to the molecular structure of the silica gel silica gel seal ring has good air permeability and the gas has good selectivity, and because of its non-toxic tasteless take in many more food and medical industries are used to silicone seal. Excellent insulating performance is its another advantage, but in increasing carbon black material, nickel powder, aluminum powder, etc can increase the conductivity. Silicone seal and hygroscopicity of the moisture absorption can work environment and have the effect of isolation, but water vapor resistance is poor. Say so many advantages of silicon rubber sealing ring.


the shortcoming of silicone seal is also obvious, its shortcomings in what environment determines its not very suitable for making first under the pressure of work more than 50 pounds working environment wasn't silica gel seal, silicone rubber although compatible with most of the oil, compounds and solvent, can have very good acid and alkali, but for hydrogen alkanes and aromatic species of oil, there is no resistance. And is not recommended in most concentrated solvent, oil, concentrated acid and diluted caustic soda solution used in the silicone seal. Special silicone seal also has some special ingredients of radiation resistant, fire resistant, oil resistant performance, but the downside is that mechanical properties of silicon, silicon rubber has been poor, stretch in the work environment, tearing, strong wear environment does not recommend the use of silica gel seal, usually under paragraph only used as a static seal, please.

the role of various silicone seal ring





a v-shaped sealing ring, is a kind of elastic rubber sealing ring of the role of axial, used as a shaft without pressure seal. Sealing lip has good mobility and adaptability, can compensate the larger tolerance and angular deviation, can prevent the internal leakage of grease or oil to the outside, also can prevent splashing water or dust intrusion from the outside.





type O sealing ring:


it is mainly used for static seal and reciprocation seal. When used for rotating seal, only in low speed rotary sealing device.


torque type sealing ring:





general installation on the outer circle or within the circle cross section inside the rectangular groove for sealing role.


torque type sealing ring:


general installation on the outer circle or within the circle cross section inside the rectangular groove for sealing role.


Y type sealing ring:


are widely used in reciprocating dynamic sealing device. In addition, there is spring tension ( Spring energy storage) In PTFE sealing materials and sealing ring,


into a spring, have the O type spring, V type spring, u-shaped spring.


hole with YX type sealing ring:


the purpose: used in hydraulic cylinder reciprocating motion of piston seal.


scope of application: TPU: general, general equipment hydraulic cylinder hydraulic cylinder.


hole with YX type sealing ring:


the purpose: used in hydraulic cylinder reciprocating motion of piston seal.


scope of application: TPU: general, general equipment hydraulic cylinder hydraulic cylinder.


YX type hole with ring:


product use: this standard is suitable for the cylinder pressure is greater than 16 mpa when used with YX type sealing ring, or eccentric cylinder force, protecting secret


the role of sealing ring.


shaft with YX type sealing ring:


the purpose: used in reciprocating motion in the hydraulic oil cylinder piston rod sealing applicable scope: TPU: general, general equipment hydraulic cylinder hydraulic cylinder.


CPU: engineering machinery with hydraulic cylinder and the high temperature and high pressure oil cylinder.


shaft with YX type baffle ring:


product use: this standard is suitable for the cylinder pressure is greater than 16 mpa when used with YX type sealing ring, or eccentric cylinder force, protecting secret


the role of sealing ring. Working temperature: - 40 ~ + 100 ℃


O rubber seal:


the purpose: the standard of the O rubber sealing ring used in various mechanical equipment and hydraulic pneumatic system and components, the pressure, temperature


and the different liquid and gas medium, plays a role of sealing under static or motion.


O ring with ring:


product use: this standard is suitable for the cylinder pressure is greater than 10 mpa when used with o-rings.


J type frameless shield:


the purpose: used in reciprocating motion cylinder, cylinder piston rod or stem the leakage place dustproof effect.


does seal sealing performance is good, service life, high dynamic pressure seal working life is higher than conventional rubber seal products 5 - 10 times, the highest


this is some of the function and purpose of all kinds of silicone seal, need friends welcome to customize.
