The bearing seal maintains lubrication where needed and helps protect the working part from abrasive particles and corrosive moisture. The seals are precisely configured to provide extremely low friction and excellent contamination resistance. It is perfect for high speed or low torque equipment as well as dusty environments. Moreover, the seal is reasonably designed to provide superior resistance to foreign particles.
The gasket made by DMS SEALS is uniquely mechanical and thermally stable and it has excellent oxidation resistance. Compared with other thermoplastics, it can be applied to components such as valves and bushings, with higher wear resistance, higher mechanical properties and thermal fatigue resistance. At the same time, it has excellent oil resistance (alkane oil), heat resistance, water resistance, aging resistance, air tightness and excellent adhesion. It is commonly used in media such as water, oil, and natural gas.
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.
Diffusion leakage: Driven by the concentration difference, the medium leaks through the material transfer generated by the sealing gap or the capillary of the sealing material. Diffusion is the result of molecular motion and is not unidirectional. When the sealing pressure difference is extremely small or in a vacuum state, or when sealing permeable substances such as nitrogen and hydrogen, as well as highly toxic and radioactive substances, special attention should be paid to the leakage and diffusion.
Due to the volume and weight limitations of the system, it is impossible to install an ideal filtration and cooling system. High temperature, high pressure, and high speed cause the hydraulic oil to deteriorate easily, and the mechanical parts are also prone to erosion and stains. There are many stains and impurities in hydraulic oil, but it cannot be thoroughly filtered, which is the aspect of endogenous stains. All kinds of dust in the working environment may be very large, and it will inevitably enter the hydraulic system in multiple ways, causing oil pollution, which is an external stain. Therefore, the sealing system is required to be resistant to stains.
Supplied in rolls or open loops. The open ring can be directly installed and used, but it must be cut when the roll is used, and the cutting length must be calculated in advance: there can only be one opening, the opening form is an oblique 45° opening, and the opening distance is about 3-15mm, or the diameter of the guide ring 3-5% of . Under normal circumstances, the openings are oblique openings. Straight openings or zigzag openings are rare and have specific uses and purposes. There are two purposes for the opening. The first is to facilitate installation. If it is not opened, it is an integral ring, which is difficult to install or impossible to install, so it must be opened. Secondly, the opening and a certain opening distance are reserved to facilitate the automatic coordination of volume changes. Otherwise, the movement may be stuck or the moving parts may be pulled due to the excessive expansion of the guide belt under certain conditions. Coiled ones are relatively cheap, and the same coil can be used to make guide rings of different sizes. Read extra info on https://www.dmsseals.com/.
