Rubber O-ring important reference

Now it seems that the rubber O-ring manufacturers more and more varieties of rubber O-ring is also very much, but not particularly clear classification, most of the business is based on their dealers the necessary products for production, and form their own brand. Most of them are mold and possible errors are all customer data base to decide, and not some normative. Rubber O-ring in the technological aspects of production we need to check and make changes, then secured the abutment to keep tidy, if not kept neat butt joints, then it is too much trouble, it needs to be modified fixed in the final weld .

Rubber is super-elastic material, with good reversible deformability, wear and corrosion resistance, etc. have been widely used in various sealing properties [1--2] rubber O-ring structure is simple and convenient to install, is based on a common seal products Roth rubber ring seal mechanism, any rubber O-ring can not achieve zero leakage, the leakage rate is an important parameter seal design. Explosive containers typically use rubber O-ring seal mating flange, explosion damage can be limited within a certain range of personnel, equipment and environment to provide protection for the explosive effects shall provide test. But when the explosion products contain harmful

Explosive substances or when the need for product analysis, work process demanding explosion vessel sealing, the gas leakage rate must be less than 1 × 10-7Pa m3 / s.

After the explosion experiments typically produce within the container temperature, high pressure explosion products, quasi-static pressure rise within the vessel, a large number of high-temperature filling in the role of shock piled flange seal, seal face temperature, high pressure test. Pressure is the driving force of seal leakage, the higher the pressure, the greater the leakage; high temperatures likely to cause structural damage seals, reduced contact stress, but also make the leak rate increases. Therefore, it is necessary to experiment with rubber O-ring studies at different temperatures, the sealing performance under pressure, to provide a reference for the selection and design of the ring, in order to ensure the security of the explosion of the container.

Auxiliary rubber O-rings using the following:

? nitrile rubber (NBR)

Suitable for temperatures below 90 ? of water at room temperature;

? Viton FPM (domestic)

Apply to water at room temperature and low temperature heat transfer oil 150 ? or less;

? Viton FPM (import Kai Ming)

HTF 195 ? apply to the following;
