Abstract

The invention discloses a novel magnetizing fluid seal device. The novel magnetizing fluid seal device comprises permanent magnets, annular magnet poles and a magnetic conduction shaft cover, wherein the magnetic conduction shaft cover is sleeved with a main shaft, the annular magnet poles are connected with the magnetic conduction shaft cover in a sleeved mode, magnetizing fluid is filled in the clearance spaces between the annular magnet poles and the magnetic conduction shaft cover, the annular magnet poles are multiple, a permanent magnet is arranged between two adjacent annular magnet poles, an added magnetizing fluid device is arranged on each annular magnet poles in a matched mode, and each added magnetizing fluid device is provided with the corresponding magnetizing fluid inside. The novel magnetizing fluid seal device is simple in structure, and easy to manufacture. Further, no complex parts are required and the requirements for the shaft surface quality and clearance processing are not high. The novel magnetizing fluid seal device can realize zero leakage as long as under the tolerant pressure differential range due to the fact that the seal is formed by a fluid, and therefore the seal for an extremely toxic substance, a combustible substance, an explosive substance, a radioactive substance and particularly a precious substance and a substance with high purity can be realized.

Description

technical field [0001] The invention relates to the sealing field of chemical reaction kettles, in particular to a novel magnetic fluid sealing device. Background technique [0002] In petrochemical and other industrial production, many reaction processes are carried out in liquid phase or gas phase under high temperature and high pressure conditions, and there is a fluid sealing problem in the connection system. If the sealing performance of the equipment cannot be guaranteed and the working medium leaks, it will cause material loss and energy loss, resulting in environmental pollution, production failure, and even endangering human health and life safety. The sealing of highly toxic, flammable, and explosive substances is an urgent problem to be solved. The existing sealing devices cannot achieve self-healing performance, and production safety cannot be guaranteed during the reaction process. Contents of the invention [0003] In order to overcome the disadvantages of t...
