Excellent seals manufacturer
Best seal supplier? DMS Seals is a scientific and technical mechanical seal manufacturer and oil seal supplier specializing in seal production, sealing material development, and the conception of sealing solutions for special working conditions. We have 120 employees, including 70 senior technicians. DMS Seals has a number of invention patents and leading production processes. The R&D team is able to design and develop Rubber Seal & Hydraulic Seals for various mechanical sealing systems under complex conditions. We have already passed the certification of ISO 9001 and TS 16949. Find more information at ptfe seals manufacturer.
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.
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.
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.
Construction machinery sealing system requirements: High and low temperature resistance Because of continuous work for a long time, if it is outdoors in summer, the hydraulic oil temperature of the machine may exceed 100°C, which requires the seal to be resistant to high temperature. If it is outdoors in winter, the temperature may be around -40°C when it is just turned on, and the seals are required to be resistant to low temperatures. Therefore, the sealing system is required to withstand a wide temperature range. The machine itself walks. Due to the limitation of volume and weight, the hydraulic oil tank is generally relatively small.
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 on https://www.dmsseals.com/.
