Abstract

Uszczelnienie hybrydowe z ciecza magnetyczna dla walu obrotowego, charakteryzuje sie tym, ze zawiera tulejki kolnierzowe (3) przedzielone wielokrawedziowymi nabiegunnikami (6) o przekroju prostokatnym z umieszczonym pomiedzy nimi magnesem trwalym (5), które sa osadzone nieruchomo w obudowie (2) lub na ruchomym wale (1). W komorach utworzonych pomiedzy tulejkami kolnierzowymi (3), a wielokrawedziowymi nabiegunnikami (6) o przekroju prostokatnym znajduja sie osadzone na wale (1) lub w obudowie (2) nabiegunniki (4) w ksztalcie tulejek kolnierzowych, na których umieszczone sa przylegajace do kolnierzy tulejek magnesy trwale (7), a nastepnie wielokrawedziowe nabiegunniki (8) o przekroju prostokatnym. Ciecz magnetyczna (9) utrzymywana jest silami pola magnetycznego w pierscieniowych szczelinach, utworzonych pomiedzy wystepami uszczelniajacymi nabiegunników (4, 8), a powierzchniami walcowymi tulejek kolnierzowych (3) oraz wystepami uszczelniajacymi nabiegunników (6), a powierzchniami walcowymi nabiegunników (4).The hybrid liquid magnetic seal for a rotary shaft is characterized by the fact that it contains flange bushes (3) separated by multi-edge poles (6) with a rectangular cross-section with a permanent magnet (5) between them, which are fixed in the housing (2) or on moving shaft (1). The chambers formed between the flange bushes (3) and the multi-edge poles (6) with a rectangular cross section are mounted on a shaft (1) or in the housing (2) the poles (4) in the shape of flange bushes, on which flanges are adjacent permanent magnets (7), followed by multi-edge poles (8) with a rectangular cross-section. The magnetic fluid (9) is held by the forces of the magnetic field in the ring gaps formed between the sealing protrusions of the pole shoes (4, 8) and the cylindrical surfaces of the flange bushes (3) and the sealing protrusions of the pole shoes (6) and the cylindrical surfaces of the pole shoes (4).
