High-Temperature Waterproof NBR/FKM/SILICONE Mechanical Seal for Chemical Pump Product DescriptionThe mechanical seal is a shaft seal device that relies on a pair or several pairs of end faces that are perpendicular to the shaft to slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and is matched with auxiliary seals to achieve leakage prevention.It is a shaft seal device for rotating machinery.StructureThe main componentsMoving ring, static ring, cooling device, and compression spring (depending on the specific equipment).Auxiliary sealThe sealing ring (O-shaped, X-shaped, U-shaped, wedge-shaped, rectangular flexible graphite, PTFE coated rubber O-ring, etc.).Elastic Compensation MechanismSpring, push ring, spring seat, and key or various screwsStatic, Dynamic RingThe function of the end face seal is to make the sealing surface closely fit to prevent the medium from leaking. It requires static and dynamic rings to have good wear resistance Auxiliary sealIt mainly plays the role of sealing the static ring and the moving ring, and also plays the role of floating and buffering. Guarantee the tightness between the static ring and the gland, and the tightness between the moving ring and the shaft or bushing Elastic Compensation MechanismA new type of wear-resistant impeller newly developed by our company is made of Al2O3 as the main raw material, rare metal oxide as the flux, and special corundum lined with high-temperature roasting at 1,700 degrees. The Rockwell hardness is HRA80- 90, the hardness is second only to diamond, far exceeding the wear resistance of high chromium cast iron and the acid resistance of stainless steel. Different ModelsSingle face A pair of sealed facesFeatures: No external sealing liquid supply system is required, but a self-flush system is required, easy to manufacture and disassemble, and simple in structureApplicable: general liquid occasions, such as oil bodies, etc. When combined with other auxiliary systems, it can be used in suspended particles, high-temperature and high-pressure liquids, etc.Multi-end face Two pairs or more of sealing end facesFeatures: Sealing liquid needs to be introduced for sealing, lubrication, flushing and cooling, and the pressure of the sealing liquid is 0.05-0.15Mpa higher than the pressure of the mediumApplicable: Suitable for corrosion, high temperature, liquefied gas with solid particles and fibers, poor lubrication medium, and volatile, flammable, explosive, toxic, easy to crystallize and other mediaMulti-spring Features: There is a group of springs, and the force on the end face is uniform, but the spring wire is thin, the corrosion resistance is poor, and the installation size is strict.Applicable: occasions with a heavy load, large shaft diameter, high speed, and low corrosion.
