The radial force of our rotary seals on the shaft and the distribution is very reasonable. It can achieve the optimal “critical oil film thickness” working condition and always maintain critical lubrication. We guarantee that our rotary seal can help the machine get the sharpest “peak” pressure distribution with the least radial force, providing the best sealing effect. The bearing seal is designed by DMS SEALS to isolate the moving metal part, guiding the piston and piston rod of the hydraulic cylinder to move in a certain direction and it can help withstand lateral loads. It helps prevent any direct contact between the piston metal and the cylinder metal and prevents strain and seal damage on the inner surface of the cylinder.
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.
The rod seals can be operated with or without lubrication. We guarantee strong dimensional stability and a low coefficient of friction. Changes in temperature do not affect its performance. It is easy to install and can be used with piston rods with the larger diameter and heavy-duty hydraulic rod sealing systems to provide a tight and excellent seal. DMS Seals with 12+ years of experience for manufacturing rod seals, we are confident to provide top quality & satisfying product. There are hydraulic rod seals, piston rod seals, etc for selection, welcome to contact us for further details.
Influence of flange form: Different flange forms require different gaskets. Smooth-faced flanges are generally only used for low pressure, with soft thin gaskets; under high pressure, if the strength of the flange is sufficient, smooth-faced flanges can also be used, but thick soft gaskets should be used, or inner belt reinforcement should be used. Wound gasket for ring or reinforcement ring. In this case, metal gaskets are also not suitable, because the required pressing force is too large, resulting in large deformation of the bolts, making the flange difficult to seal. If a metal gasket is to be used, the smooth surface should be reduced to reduce the contact area with the gasket. In this way, under the condition of the same bolt tension, the compressive stress of the reduced narrow smooth surface will increase.
Construction machinery, also known as construction machinery, is mainly used for mechanical and electrical equipment for the construction, renovation and maintenance of various buildings. Widely distributed in industrial and civil construction, urban construction, national defense construction projects, transportation construction, mining and other raw material industrial construction and production, agriculture, forestry and water conservancy construction, sanitation and environmental protection industries. It contains a wide range of types, such as excavators, loaders, cranes, pump trucks, pile drivers, hydraulic breakers, pavers, graders, rock drills, etc.
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. Read more information on dmsseals.com.
