High quality o rings factory: Every other leak path within the mechanical seal is blocked with the use off a gasket, o-ring, wedge (Rubber, PTFE or Flexible Graphite). The other key aspect of a mechanical pump seal is how to maintain the seal. Springs (single or multiple), a metal bellows or just compressed elastomers are used to provide the needed energy to keep pressing the seal faces together. The load the seal faces receive are engineered into the design of the seal. The choice of what is the best depends on the temperature, and nature of what is being sealed (viscosity, abrasiveness, weight (is it a slurry?)). Cartridge Seals are pre-assembled package of mechanical seal components making installation much easier with fewer points for potential mechanical pump seal installation errors to occur. Mechanical seals occasionally require a seal pot to provide a buffer fluid for your double cartridge seals. Seal pots can not only provide a lubricating buffer, but they can also heat or cool the barrier fluid they contain. Find additional info on https://www.dmsseals.com/rod-seals.
Basics of fluid pump sealing – A mechanical seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft. When sealing a centrifugal pump, the challenge is to allow a rotating shaft to enter the ‘wet’ area of the pump, without allowing large volumes of pressurized fluid to escape. To address this challenge there needs to be a seal between the shaft and the pump housing that can contain the pressure of the process being pumped and withstand the friction caused by the shaft rotating. The gap between the faces on a typical seal is as little as 1 micron – 75 times narrower than a human hair. Because the gap is so tiny, particles that would otherwise damage the seal faces are unable to enter, and the amount of liquid that leaks through this space is so small that it appears as vapor – around ½ a teaspoon a day on a typical application.
DMS SEALS’ s bonded seal is ideal for being applied to threaded pipe fittings and plug sealing in Metric, British and BSP systems. The seal has no special requirements for the positioning and processing techniques of the seal groove, so it is an ideal accessory for fast and automatic installation that we highly recommend. The operating temperature range is -30°C ~ 100°C, and the working pressure is less than 39.2 MPa. It is commonly used in a hydraulic oil medium.
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.
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.
The guide belt is a belt-shaped member that guides the moving parts. Its main function is to guide. In order to realize the function of guidance, it must support the guided member, and guide and correct its motion trajectory. In order to realize the guiding function well, it also requires isolation, shock absorption and noise reduction of the guiding parts. Guide belts are mainly used in oil cylinders and cylinders. Due to their excellent performance, they are also widely used in other motion mechanisms. Find extra details on https://www.dmsseals.com/.
DMS Custom Rubber Rings, O Ring Company & factory covers an area of more than 10,000 square meters and the factory area is 8,000 square meters. Our production equipment and test equipment are at the leading level in the industry. We are one of the largest companies in China specializing in the production and development of seals. We have long-term communication and cooperation with many universities and research institutions at home and abroad.
Key points of engineering mechanical seal design: Select a reasonable sealing scheme, focusing on the above requirements. First of all, the dustproof performance must be good. More than 80% of the failures of the hydraulic system are directly or indirectly derived from the stains in the system. Choose the best seals For seals of the same structure, the product quality of each company varies greatly. On the whole, the quality of large foreign seal companies is relatively stable, but the probability of encountering fakes is too high. Sometimes the so-called direct supply is not reliable. In terms of domestic seals, most of them are not very good, but at present, some manufacturers’ products have been chasing or even surpassing imported products, with stable and reliable quality, such as tetrafluoroethylene and rubber seals produced by Damson Sealing.
The rotary seal from DMS SEALS is a dynamic sealing component that is installed between the rotating shaft and the stationary parts to seal the lubricating oil and prevent external dust and debris from entering the inside of the device. When selecting the material, we fully consider the working medium, working temperature and the adaptability of the lip when the shaft rotates at high speed. It has a remarkable sealing performance and can maintain a great sealing effect for a long time.
