磁流体密封是70年代前后发展起来的一项新技术。本文应用热力学和磁流体动力举,从理论上阐述磁流体密封承压能力的产生及其计算方法,并推导每级密封承压能力的计算式Δp=μ_oM_SH。
Magnetic fluid seal is a new technology developed around the 70s. In this paper, thermodynamics and magnetohydrodynamic motion are used to explain the generation of magnetic fluid seal bearing capacity and its calculation method theoretically, and the calculation formula of pressure bearing capacity of each seal is deduced Δp = μ_oM_SH.
