Abstract

A magnetic liquid sealing device used for multi-channel gas delivery between a rotating system and a static system belongs to the sealing field. The device solves the problem that the existing multi-channel gas delivery device can only deliver gas under the condition that no relative movement exists at a gas inlet / outlet and cannot deliver the gas under the condition that relative movement exists at the gas inlet / outlet. The system comprises a rotating shaft, a left shaft sleeve assembly, a right shaft sleeve, a magnetic liquid sealing unit and the like. Due to the fact that the magnetic liquid sealing unit is arranged between annular cavities formed by gas outlet shaft sleeves and the rotating shaft for sealing, the multi-channel gas delivery between the static system and the rotating system of can be achieved, gas mixing between the channels cannot happen, and zero leakage is achieved in the gas delivery process.

Description

technical field [0001] The invention belongs to the sealing field and can realize multi-channel gas delivery between two relative rotating systems. Background technique [0002] Gas delivery devices are widely used in industrial heat exchange, medicine and other fields, and the sealing of superconducting generator cooling systems. Most of the existing gas delivery devices realize the gas exchange between two relatively static systems. [0003] The gas delivery device between the existing relative rotation systems has serious gas leakage, and it is difficult to realize multi-channel gas delivery. [0004] The magnetic liquid is a stable new functional material formed by nano-scale magnetic particles highly dispersed in the carrier liquid. Sealing is an important field of application for ferrofluids. Magnetic liquid sealing technology is gradually being used by more and more industries due to its advantages of zero leakage, no mechanical wear, long life and simple structure...
