O型圈

    O型橡胶密封圈是经由过程正在模具中硫化构成其截面成圆形的环状密封圈。它具有构造简朴、机能牢靠、价格低廉、易于选配等奇特的长处。它的规格尺寸用它的内径d1和圆状横截面直径d2去界说,我公司可供应种种尺寸的O型圈,尺度质料有丁氰橡胶NBR,氟橡胶FKM,三元乙丙橡胶EPDM,硅橡胶VMQ,氢化丁氰橡胶HNBR,氟硅橡胶FVMQ,氯丁橡胶CR等,其他质料也可供应,请征询我公司021-37588159

    大部分国度对O形密封圈皆制订系列产品尺度,个中美国尺度(AS 568)、日本尺度(JISB2401)国际标准(ISO 3601/1)较为通用。

O-ring is mainly used in fluid static application (For example, water, oil, air, chemicals solvent, chemicals, etc. ) . The temperature range is from -60 up to 220 . The pressure in static application should be less than 20MPa, which varies with different materials. Sometimes O-ring is used in dynamic application with the pressure less than 5MPa and also used in semi-conductor vacuum seal.

Feature:

·                                 (a) Various materials and hardness for o-ring customer's option, include FKM, Nitrile, EP, Silicone, Alfas, Polyurethane ,Neoprene etc.

·                                 (b) All O Rings are made according to international standard: ISO 3601, AS 568A, DIN 3771, JIS B2401.

·                                 (c) Mix material by ourselves.

·                                 (d) Mold making by ourselves.

·                                 (e) Excellent environment of manufacturing.

International standard

All o-rings are made according to international standard: ISO 3601, AS 568A, DIN 3771, JIS B2401. There arevarious materials and hardness for customer's option, include:FFKM , FKM, Nitrile, EP, Silicone, ACM, Flour Silicone, Alfas, Polyurethane , Neoprene etc. We meet the highest industrial standards and requirements of our customers.

O Ring Use For :

An o ring is a loop of elastomer with a round (o-shaped) cross-section used as a mechanical seal or gasket. They are designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

Theory and Design

O Ring mounting for an ultra-high vacuum application . Pressure distribution within the cross-section of the O Ring. The red lines are hard surfaces, which apply high pressure. The fluid in the seams has lower pressure. The soft O Ring bridges the pressure over the seams. Orings are one of the most common yet important elements of machine design. They are available in various metric and standard sizes. The UKstandards sizes are known as BS Sizes and typically range from BS001 to BS932. The most common standard sizes in theUSare controlled by SAE AS568. In general orings are specified by the inside diameter and the cross section diameter (thickness). The O Ring is one of the simplest, yet most engineered, precise, and useful seal designs ever developed.

Typical Applications

Successful o-ring joint design requires a rigid mechanical mounting that applies a predictable deformation to the o ring. This introduces a calculated mechanical stress at the o ring contacting surfaces. As long as the pressure of the fluid being contained does not exceed the contact stress of the o ring, leaking cannot occur.

High temperature applications

In some high temperature applications, it may need to be mounted in a tangentially compressed state to compensate for the Gow-Joule effect.

Our products have passed the certification: USA NSF/FDA, German DVG KTW, UK WRAS. We can also supply OEM service for customers. Please contact us.
