Abstract

The invention relates to a combined reciprocating sealing device of magnetic liquid, a C-shaped slip ring and a Y x type seal ring. The connection of the components of the device is as follows: a first O-shaped rubber sealing ring (3), the Y x type seal ring for a first shaft (4) and a first C-shaped slip ring (5) are respectively arranged into a circular groove provided on a first permanent seat(2); a second O-shaped rubber sealing ring (15), the Y x type seal ring for a second shaft (14) and a second C-shaped slip ring (13) are arranged into a circular groove provided on a second permanentseat (16); and the first permanent seat, a first pole piece (7) with the O-shaped rubber sealing ring, a permanent magnet (10), a second pole piece (11) with the O-shaped rubber sealing ring and the second permanent seat are successively arranged at the bottom of the cavity of a sealing socket (1) with the O-shaped rubber sealing ring and are in threaded connection with the sealing socket throughbolts, and an end cover compresses the above components tightly. Before installation, the magnetic liquid is injected. The combined reciprocating sealing device solves the leakage problem of the piston rod of a reciprocating compressor.

Description

technical field [0001] The invention belongs to the field of mechanical engineering sealing, and is particularly suitable for the reciprocating motion sealing of shafts whose temperature is below 150 DEG C and whose sealing medium is gas in equipment such as vacuum coating machines and compressors. Background technique [0002] A compressor is a general-purpose machine used to compress gas to increase its pressure or transport gas. Currently the most widely used are reciprocating, screw and centrifugal. Among them, reciprocating compressors are widely used in mining, metallurgy, petroleum, chemical and other industrial fields due to their unique advantages such as high efficiency and high pressure. However, the leakage phenomenon of reciprocating compressors is ubiquitous, and because of its wide application, the seriousness of the problem is even more apparent. Especially the leakage of compressors that compress and transport flammable, explosive and highly toxic gases ca...
