Introduction to the functions of various sealing rings

v-shaped sealing ring

is an elastic rubber sealing ring with axial effect, which is used as the non pressure seal of the rotating shaft. The sealing lip has good mobility and adaptability, can compensate for large tolerances and angular deviations, can prevent internal grease or oil from leaking outward, and can also prevent the invasion of external splash or dust

o-ring

is mainly used for static seal and reciprocating seal. When used for rotary motion sealing, it is limited to low-speed rotary sealing device

v-shaped seal ring

is generally installed in the groove with rectangular section on the outer circle or inner circle to play a sealing role

y-shaped sealing ring

a wide range of machines for you to choose from! It is widely used in reciprocating sealing devices. In addition, there is a spring tension (spring energy storage) seal ring, which adds a spring into the PTFE sealing material. There is an O-shaped spring, and the V-shaped spring is not suitable for the stress analysis spring and U-shaped spring of glass fiber reinforced plastic pipe according to the stress classification method of steel pipe

YX type sealing ring for hole

briefly describe the use of the product: it is used to seal the piston in the reciprocating hydraulic cylinder. Scope of application: TPU: general hydraulic cylinder, general equipment hydraulic cylinder. CPU: hydraulic cylinder for construction machinery and oil cylinder for high temperature and high pressure. Material: Polyurethane TPU, CPU, rubber product hardness: HS85 ± 2 ° a working temperature: tpu:- 40 ~ +80 ℃ cpu:-40 ~ +120 ℃ working pressure: ≤ 32Mpa working medium: hydraulic oil, emulsion

YX type hole retaining ring

simple description of product use: this standard is applicable to the use of YX type sealing ring when the working pressure of the oil cylinder is greater than 16MPa, or when the oil cylinder is eccentrically stressed, it plays the role of protecting the sealing ring Working temperature: -40 ~ +100 ℃ working medium: hydraulic oil, emulsion, aquatic products hardness: HS 92 ± 5A material: polytetrafluoroethylene

YX type sealing ring for shaft

simple description product purpose: used for sealing the piston rod in reciprocating hydraulic cylinder. Scope of application: TPU: general hydraulic cylinder, general equipment hydraulic cylinder. CPU: hydraulic cylinder for construction machinery and oil cylinder for high temperature and high pressure. Material: Polyurethane TPU, CPU, rubber product hardness: HS85 ± 2 ° a working temperature: tpu:- 40 ~ +80 ℃ cpu:-40 ~ +120 ℃ working pressure: ≤ 32Mpa working medium: hydraulic oil, emulsion

YX type retaining ring for shaft

simple description of product use: this standard is applicable to the use of YX type sealing ring when the working pressure of the oil cylinder is greater than 16MPa, or the role of protecting the sealing ring when the oil cylinder is eccentrically stressed Working temperature: -40 ~ +100 ℃ working medium: hydraulic oil, emulsion, aquatic products hardness: HS 92 ± 5A material: polytetrafluoroethylene according to: enterprise standard

o-type rubber seal ring

(GB) briefly describe the use of the product: the O-type rubber seal ring in this standard is applicable to hydraulic and pneumatic systems and various mechanical equipment and components. Under the specified pressure, temperature and different liquid and gas media, It plays a sealing role in static or moving state. Working temperature: -40 ~ +230 ℃ working pressure: <10 ~ 220kg, f/cm working medium: air, water, oil product hardness: 40 ~ 85 ± 2A material: nitrile rubber, silica gel, fluororubber, ethylene propylene rubber

retaining ring for O-ring

Simple description of product use: this standard is applicable to use with O-ring when the oil cylinder pressure is greater than 10MPa. Working temperature: -100 ~ 200 ℃ working medium: hydraulic oil, emulsion, water material: polytetrafluoroethylene according to: jb/zq is suitable for being the top event in the Western plastic industry GB

J-type frameless dust ring

simple description product usage: used for reciprocating oil cylinders, gas (3) adjustable buffer valves, the steel ball and ball seat are not tightly closed, and the exposed part of the piston rod or valve rod in the cylinder plays a dust-proof role. Scope of application: TPU: engineering machinery, general machinery, cylinder types, various valves, etc. Cpu: oil cylinder of construction machinery and oil cylinder with poor working conditions. Material: polyurethane, nitrile rubber working temperature: -40 ~ 120 ℃, product hardness: HS 80 ± 5A according to: jb/t ※ the sealing ring has excellent sealing performance and high working life. The working life of dynamic pressure sealing is 5-10 times higher than that of conventional rubber sealing products, up to dozens of times. Under some conditions, it can have the same life as the sealing matrix. ※ The friction resistance of the sealing ring is small, and the dynamic and static friction are equal, which is 1/2-1/4 of the friction of the "0" shaped rubber ring, which can eliminate the "crawling" phenomenon of movement at low speed and low pressure. ※ The sealing ring is highly wear-resistant, and has the function of automatic elastic compensation after the sealing surface is worn. ※ The sealing ring has good self-lubricating performance. It can be used as oil-free lubrication seal. ※ The seal ring is simple in structure and easy to install. ※ Working pressure of sealing ring: 0-300mpa; Working speed: ≤ 15m/s; Working temperature: -55-250 ℃. ※ Applicable media of sealing ring: hydraulic oil, gas, water, mud, crude oil, emulsion, water glycol, acid, alkali, chemicals, etc
