Abstract

The invention discloses a magnetic liquid sealing device, which comprises a casing, a rotating shaft, a first bearing, a second bearing, a first magnetic sealing assembly and a second magnetic liquid sealing assembly. The casing is provided with a cavity, and the rotating shaft passes through the casing. and rotatable relative to the housing, the rotating shaft is at least partially located in the chamber, the first bearing and the second bearing are both located in the chamber, the first bearing and the second bearing are respectively sleeved on the rotating shaft, and the first bearing and the second bearing Arranged at intervals in the axial direction of the rotating shaft, the first magnetic sealing assembly and the second magnetic liquid sealing assembly are both located in the chamber, the first magnetic sealing assembly and the second magnetic liquid sealing assembly are respectively sleeved on the rotating shaft, and the first magnetic liquid sealing assembly The assembly is located between the first bearing and the rotating shaft, and the second magnetic liquid sealing assembly is located between the second bearing and the rotating shaft. The magnetic liquid sealing device of the present invention can reduce the axial volume of the magnetic liquid sealing device and improve the application range of the magnetic liquid sealing device.

Description

technical field [0001] The invention relates to the technical field of magnetic liquid sealing, in particular to a magnetic liquid sealing device. Background technique [0002] Magnetic liquid sealing technology is used by more and more industries due to its advantages of zero leakage, no wear, long life and simple structure. However, the magnetic liquid sealing device in the related art has a relatively large axial volume, and cannot be applied in the case of a small installation space. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the embodiment of the present invention proposes a magnetic liquid sealing device, which can reduce the axial volume of the magnetic liquid sealing device and improve the application range of the magnetic liquid sealing device. [0004] The magnetic liquid sealing device according to the embodiment of the present invention includ...
