磁流体密封是磁流体最成功的应用之一。液体环境中的磁流体密封理论尚未发展。本文主要研究了水环境中粘性和磁粘效应对磁流体密封性能的影响。制备了三种不同粘度、饱和磁化强度值相近的发动机油基磁流体，并设计了多级磁密封结构。用旋转流变仪测量了不同工况下磁性液体的磁粘效应。设计了一个试验平台和多级磁密封结构，用于临界压力值和耐久性试验。实验结果表明，磁流体的粘度是影响其在水环境下密封性能的决定性因素，并对实验结果进行了定性解释。
ABSTRACT The magnetic fluid seal is one of the most successful applications of magnetic fluids. The theory of magnetic fluid seals in liquid environments has not been developed. This work mainly presents an experimental study of the influence of viscosity and magnetoviscous effects on the performance of a magnetic fluid seal in a water environment. Three engine oil–based magnetic fluids of different viscosities and similar saturation magnetization values were prepared and a multistage magnetic seal structure was designed. The magnetoviscous effect of the magnetic fluids under different working conditions was measured with an advanced rotational rheometer. An experimental platform and a multistage magnetic seal structure were designed for the critical pressure value and durability tests. The experimental results show that the viscosity of a magnetic fluid is a decisive factor in its sealing performance under a water environment and a discussion is presented that can explain the experimental results qualitatively.
