  • Sealing Using Fluids, Sealing Without Contact, And Removal Of Oil (AREA)

Description

лов, НС будет удерживать ее от вытеснени  вдоль вала 1.fishing, the NA will keep it from being pushed along shaft 1.

Таким образом, нри посто нной циркул ции жидкости в магнитном уплотнении, та часть жидкости, котора  контактирует с рабочим объемом уплотн емой камеры, посто нно обмениваетс  со всем объемом жидкости, наход щейс  во внутренней кольцевой полости 5, в результате чего повышаетс  срок службы уплотнени , его надежность.Thus, in the constant circulation of fluid in a magnetic seal, that portion of the fluid that is in contact with the working volume of the chamber to be sealed is constantly exchanged with the entire volume of fluid in the inner annular cavity 5, thereby increasing the service life of the seal, its reliability.

Предмет изобретени Subject invention

Магнитное уплотнение вала в корпусе с кольцевой магнитной системой и магнитной запирающей жидкостью в уплотн емом зазоре, отличающеес  тем, что, с целью повышени  надежности уплотнени  в работе, магнитна  кольцева  система выполнена в видеA magnetic shaft seal in a housing with an annular magnetic system and a magnetic locking fluid in the sealing gap, characterized in that, in order to increase the reliability of the sealing in operation, the magnetic ring system is designed as

установленного на валу подвижного посто нного магнита, концентрично которому в корпусе установлен другой неподвижный посто нный магнит, образующие внутреннюю кольцевую полость, сообщающуюс  со щел ми и каналами в них, причем каналы подвижного посто нного магнита сообщаютс  с внутренней кольцевой полостью на поверхности меньшего диаметра, а с полюсными щел ми - на поверхности большего диаметра.mounted on the shaft of a movable permanent magnet, concentric with which in the case another fixed permanent magnet is mounted, forming an internal annular cavity communicating with slots and channels in them, the channels of the movable permanent magnet communicating with the internal annular cavity on the surface of a smaller diameter, and with pole gaps on a larger diameter surface.
