Magnetic fluid seals belong to the class of non-contact seals. They are used as protective seals for vacuum systems, high speed shafts, precision mechanics, and electromechanical devices. The proper functioning of the magnetic fluid seal is related to creating and maintaining the continuity of the fluid ring on the sealing stage. This is achieved by appropriately shaped magnetic field distribution...
The paper presents the results of modelling and experimental validation of a developed mathematical model, describing the influence of selected factors on the axial force generated by magnetic fluids used as lubricants in thrust slide bearings. The model takes into account the physical properties of the magnetic fluid (density, saturation magnetization), bearing geometry (diameter, gap height, magnetic...
Magnetic fluids are substances whose rheological properties can be actively influenced by treatment with a magnetic field. Two main types of magnetic fluids can be distinguished: ferromagnetic fluids, and magnetorheological fluids. Ferrofluids are mostly used in sealing engineering, whereas magnetorheological fluids are usually applied in controlled systems for the dissipation of mechanical energy,...
