The O-ring of the dynamic seal is used in an interference fit to clamp around the shaft, thereby preventing wear on the shaft surface. 2. The product features a magnetic design, which uses magnetic force to keep the stationary and rotating rings in close contact at all times. Achieve zero leakage. 3. High-carbon fiber, a wear-resistant material, is used as the friction pair between the stationary and rotating rings, resulting in a low coefficient of friction. 4. The product has a compact design and is installed in the original oil seal location, requiring no modifications to the equipment. 5. The operating temperature can range from -40 to 200 degrees; special conditions can be addressed through custom design. 6. Service life of over 25,000 hours. Product parameters: Pressure resistance: 0.11 MPa; Temperature resistance: -40 to 200 degrees; Linear speed: 28 m/s; Radial runout: 0.3 mm; Axial movement: 0.3 mm; Product thickness: 14 mm (minimum); Materials: Phosphor bronze, aluminum alloy, stainless steel; Seal material: NBR/FKM; Media: Water, oil, dust, gases; Applicable operating conditions: Suitable for oil supply and lubrication in chambers with full oil levels or under pressure; operating speed: 0–5000 revolutions per minute; operating temperature: -40 to 200 degrees, with temperatures of up to 350 degrees possible in special cases. Equipment such as pump bearing housings, gearboxes, speed reducers, compressor bearing housings, motors, fans, vertical speed reducers, direct-drive motors for new energy vehicles, underwater equipment, and mechanical seals for replacement pumps. 7. Magnetic bearing isolators achieve sealing by bringing the sealing surfaces together under magnetic force, with additional auxiliary seals in place to prevent leakage of the working fluid. It provides sealing for relative movement between the rotating ring and the shaft, and allows axial and angular movement to automatically compensate for wear on the sealing surfaces. Compared with conventional elastomeric face seals, the main advantages of magnetic face seals are that they do not wear the shaft, have a low friction coefficient, require fewer structural components, are compact, and are easy to install. By using magnetism to replace the elastic force of elastic elements, the problem of large variations in contact load caused by manufacturing and installation errors as well as axial displacement during operation is overcome. Contact load at the sealing interface. It can be designed to be small and evenly distributed. Therefore, the magnetic face seal device has high operating capabilities (temperature, pressure difference), low wear, and low energy consumption.
