Development of magnetic fluid reciprocating motion seals
Journal of Magnetism and Magnetic Materials, 1990Abstract The operation of magnetic fluid reciprocating motion seals is affected by the carry-over and the seal deformation, on latter being the main factor. The analysis of gas dynamic processes in the seal multistage system yielded the condition of its operation. New seal structures with damper volumes and gas dynamic resistances were developed.

Magnetic fluid seal critical pressure calculation based on numerical simulations
International Conference on Advances in System Simulation, 2019Magnetic fluid seals are among the most common ferrofluid applications. One interesting area is the use of numerical simulations to determine the critical pressure, which is a basic parameter determining the possible range of seal operating pressures ...

The Pressure Loading Process among Stages of Magnetic Fluid Seal in Aqueous Environment
Tribology Transactions, 2019Magnetic fluid (MF) seals have typically been used under various vacuum and gaseous low-pressure conditions. However, there are only a few cases in which MF seals can be used in a liquid environment.

Magnetically separated Fe nanoparticles cake, with ten times higher saturation magnetization than the ferrofluid carrier, act as the main plug in the sealing stage. The burst pressure sharply increases in the concentration range where the cake fills the seal gap.
