The O-ring of DMS SEALS is often used in hydraulic and pneumatic transmission systems and has wide applications. It can be used for both static and reciprocating seals. Moreover, it can also be used in rotary sealing systems. The O-ring can be installed in a groove with a rectangular cross section on the outer or inner circle, achieving a good sealing effect. It has many advantages compared with other types of sealing rings. Its compact structure makes it easy to assemble and disassemble. Moreover, its dynamic frictional resistance is relatively small, and a single piece of O-ring can achieve sealing performance in both directions.
It adopts the most ideal design and improved sealing performance and can minimize the high strength of local stress. This type of seal is designed to simplify installation and reduce particle generation. Moreover, it can be quickly and easily installed and removed to facilitate hardware assembly. It perfectly combines a custom seal design, proprietary bonding technology, and excellent plasma resistance developed for semiconductor applications. And its unique structure can minimize common installation problems.
DMS Seals piston seals can be used very effectively in the clearance between the two chambers of the hydraulic cylinder and cylinder. The piston seal is pushed by the pressure of the fluid. Its good working performance can improve the efficiency of the machine. Due to its excellent resistance to leakage, it helps the machine to extend the machine’s working life. Our seals provide the best tight adhesion for the sealing system with low internal leakage and frictional resistance.
Leakage of gaskets: There are four types of leakage phenomenon in general gaskets: interface leakage, penetration leakage, diffusion leakage, and damage leakage. Interface leaks: The interface will leak at the sealing interface due to insufficient gasket compression, improper flange joint surface finish, and flange deformation. For interface leakage, it can be prevented by using soft gasket to clamp in the flange face. Penetration leakage: Since most of the soft materials are made of fibers, they are easily soaked by the medium, especially the pressure. Due to capillary phenomenon, the medium will permeate to the low pressure side, forming permeation.
Because the system pressure is high, the temperature is high, and the wear is particularly serious, the seal is required to have good wear resistance. Low coefficient of friction: For construction machinery such as excavators and pump trucks, the hydraulic system pressure is high, the cylinder action speed is fast, and the wear of the seal is particularly serious. Therefore, the friction coefficient of the seal must be low, so that the seal has good wear resistance and suitable life.
Support and positioning The piston and piston rod are radially supported and positioned in the cylinder barrel. Isolate the two pairs of motion pairs of piston and cylinder, piston rod and guide sleeve to prevent direct scratches, abrasions and strains between the motion pairs. Especially when the motion pairs are all steel parts, they must be isolated, otherwise they will be easily strained. The guide belt also has an important role to reduce the friction and friction work between the moving parts, reduce the ineffective work and heat. Vibration absorption and noise reduction Reduce system vibration and noise. It is mainly filled with tetrafluoroethylene and phenolic cloth, and there are also a very small amount of polyoxymethylene, nylon and soft metal. Find even more info at dmsseals.com.
