Optimization of Performance Characteristics of Magnetofluidic Seals for Wind Power Plants

The use of magnetofluidic seals are a promising direction in sealing rotating shafts wind power plants. Magnetofluidic characterized by high tightness, simplicity the design, low losses friction. Magnetic fluid seal shaft consists ring magnet and two concentrators magnetic field, forming with narrow gap which retained field is hermetic seal. forces provide balance volume under impact pressure drop centrifugal forces. With an increase speed rotation up to 10 m/s, deformation free surface at form funnel visually observed, causes decrease drop. As increases, part ejected from working area, decreases, 50 m/s there complete release depressurization In order stability forces, multilayer carbon nanotubes were introduced into it. They specific area and, accordingly, strong Van der Waals attraction. fluid, structures oriented along lines. following static load layer has been experimentally determined introduction nanocarbon structures: when coinciding axis was 100 %, for normal structure – %. seal, speed, observed 18 distance 3 mm surface. increased range 10–40 maximum effect % obtained 40 m/s. Thus, made it possible reduce influence on efficiency speeds
