Problems solved by technology

[0002] The existing research on the magnetic liquid sealing process is in its infancy. Due to the black color of the magnetic liquid and the special environment of the magnetic liquid sealing device, it is impossible to observe and measure the magnetic liquid sealing process accurately and intuitively. The process includes: how the pressure in the tooth groove of the magnetic liquid seal changes, how the magnetic liquid flows during the injection process, and the final pressure distribution of the magnetic liquid in the sealed tooth gap

Abstract

The invention relates to a magnetic liquid sealing process researching device and belongs to the technical field of mechanical engineering sealing. The magnetic liquid sealing process researching device is applicable to test research on the magnetic liquid sealing process in science and technology museums and large and medium-sized colleges. All the parts of the magnetic liquid sealing process researching device are connected with one another, wherein a transparent glass block (7) is inlaid and sealed on an outer sleeve (1); a vacuum pump (14) is communicated with a sealed space (16) through a pipeline and a valve (15) thereon and is hermetically connected to the outer sleeve; an air pressure gauge (8) is communicated with a toothed groove of a first pole shoe (4) through the pipeline and is hermetically connected to the transparent glass block; a first bearing (2), the first pole shoe (4) with a second rubber sealing ring, a permanent magnet (11), a second pole shoe with a first rubber sealing ring and a second bearing (3) are arranged on a non-magnetic shaft (9) sequentially to form a sealing component; magnetic liquid (6) is injected into the outer circumference of the permanent magnet; the sealing component is arranged on a boss of an inner hole of the outer sleeve; and a flange plate (10) is fixed on the outer sleeve, so that the sealing component can be fixed axially.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering sealing, and is particularly suitable for the experimental research of the magnetic liquid sealing process in science and technology museums, colleges and universities. Background technique [0002] The existing research on the magnetic liquid sealing process is in its infancy. Due to the black color of the magnetic liquid and the special environment of the magnetic liquid sealing device, it is impossible to observe and measure the magnetic liquid sealing process accurately and visually. The process includes: how the pressure in the tooth groove of the magnetic liquid seal changes, how the magnetic liquid flows during the injection process, and the final pressure distribution of the magnetic liquid in the sealed tooth gap. Contents of the invention [0003] The problem to be solved by the invention is to provide an experimental device for studying the magnetic liquid sealing proce...
