Original Abstract
The paper deals with design and tests of MagnetoRheological Fluid seal (MRFs) using innovative conception of magnetic circuit. The common design of magnetic seal uses ferrofluid. Low friction torque and low burst pressure are typical for this kind of seals. Replacement of the ferrofluid by magnetorheological fluid increases the burst pressure; however, the friction torque increase too. The optimum for sealing is low friction torque and high burst pressure. The new design of MRFs described in this paper meets both requirements; is based on gradient-pinch mode. The friction torque and burst pressure of this type of design and common design of MRFs were tested and compared. The new design of MRFs achieved 20 times lower friction torque that current solution MRFs. The developed MRFs combines the benefits of common FFs and MRFs.
