Title: Investigation of the possibility of creating magnetic-fluid pressure seals for reciprocal motion

Abstract

Design problems of magnetic-fluid seals were experimentally studied and solutions were proposed for their operation under conditions of reciprocal motion. Possibilities for increasing the stability of the seals by changing the geometry of the tooth and by using a damping volume and gas-dynamic drag to ensure the functionability of the multitooth system were examined. Magnetic fluid seals with two teeth on each pole with symmetric and beveled teeth were studied on a stand. Manometry determined the tightness of the seal. An elastic ring combination was placed on the shaft with a slight tension to increase the tightness of the seal. Maximum service life was found to occur when the rings were installed with slight tension and functioned in this case as piston rings.
