It is ideal for single-acting sealing of reciprocating piston rods or pistons with a wide operating pressure range of up to 20 MPa. The operating temperature range is also wide from -200°C to + 250°C. It has a diameters range from 3 mm to 1600 mm and a working speed of 5 m/s. The seal has a low coefficient of friction and the friction between the contact faces is minimal among all seal types. Moreover, the contact pressure between the mating surfaces is low. It can work without lubrication and is very wear resistant. And it has a long service life.
Rubber seals are a common type of basic component in sealing devices, and play a very important role in the contradiction between leakage and sealing. Using rubber seals is an important way to promote technological advancement and prevent and reduce environmental pollution. They are a class of rubber products that are widely used in sealing technology. Because rubber is a polymer material with valuable elasticity, a wide temperature range. It gives less stress in different media producing large deformation, which can provide contact pressure, compensate for leakage gap, and achieve the purpose of sealing.
Wiper seals are utilized to remove contaminants like moisture, soil, and dust. Some wipers or even scrapers possess a secondary lip utilized to catch any oil which might have bypassed the major seal. The secondary lip can also get rid of any bonded contaminate in the pole surface. These kinds of wipers are usually called double-edged wipers. Metallic scrapers could be used for sub zero temperature software and especially arduous software where foreign substances can deposit the pole.
The selection principle of the gasket: according to the working pressure, working temperature, the corrosiveness of the sealing medium and the form of the sealing surface. Temperature influence: In normal temperature and low pressure, use non-metallic soft honey gasket; in medium pressure and high temperature, choose metal and non-metal combination gasket or metal gasket; when temperature and pressure fluctuate greatly, choose good elasticity or self-tightening type Gaskets; in low temperature, corrosive media or vacuum conditions, gaskets with special properties should be considered.
Select the appropriate sealing material: There are many types of sealing materials, including many metals, plastics and rubbers. The same material has different performances from different companies. On the other hand, the same seal has different performances in different working conditions or different sealing schemes, so it must be carefully considered when choosing. Note: Be sure to consider seals under the premise of a reasonable sealing scheme, then consider the sealing material, and then consider the seal manufacturer. If you don’t have enough sealing experience, it is best to consider the sealing company first, and let the sealing company consider the sealing scheme and other issues, such as DMS Seals Technology Co.,Limited.
