Abstract
Магнитожидкостное уплотнение немагнитного вала, содержащее магнитную систему, включающую постоянный магнит с полюсными наконечниками, и магнитную жидкость, отличающееся тем, что снабжено ограничителем свободной поверхности магнитной жидкости, установленным между полюсными наконечниками, выполненным из немагнитного материала в виде кольцеобразного элемента, торцевые поверхности которого повторяют форму примыкающих поверхностей полюсных наконечников.A non-magnetic shaft magnetic fluid seal comprising a magnetic system including a permanent magnet with pole pieces and a magnetic fluid, characterized in that it is provided with a magnetic fluid free surface limiter installed between the pole pieces, made of non-magnetic material in the form of an annular element, the end surfaces of which repeat the shape adjacent surfaces of pole pieces.
