Abstract
In order to solve the problem of poor sealing performance of rotating machinery under the condition of small
clearance, a new type of divergent magnetic fluid seal device with small clearance and double magnetic source
is designed in this paper. The effect of magnetic fluid injection, tooth number and sealing clearance on the sealing
pressure resistance of dual magnetic source divergence were studied and compared with the experimental
value of ordinary magnetic fluid seal. The experiment results show that the pressure resistance ability of divergent
magnetic fluid seal is at least 3 times that of ordinary magnetic fluid seal, which verifies the correctness of
divergent magnetic seal with small clearance and double magnetic source pressure resistance theory, and has
important theoretical guiding significance for solving the problem of poor magnetic fluid seal performance
under small clearance.
