Influence of magnetic fluid evaporation on pressure resistance of magnetic fluid seal

Magnetic fluid seals have the advantages of zero leakage, long life, simple structure and high reliability, become one most widely used applications magnetic fluids. In this paper, effect evaporation on pressure resistance is studied. terms theory, through theoretical calculation simulation analysis, a method for established. experiments, firstly, five groups control were set up to conduct experiments under same conditions, fluids with different rates obtained; Secondly, performance was tested, flow curves, viscosity-temperature magnetic-viscosity curves obtained respectively, analyzed; Finally, sealing carried out. It found that increases static seal certain extent, which great significance.
