摘要：

Magnetic fluid seals are a new type of seal with zero leakage. Based on the requirements of the working conditions, a magnetic fluid seal device applicable to rotating shafts was designed in this study using magnetic field simulation analysis and experimental verification. The relationships between several structural variables and seal pressure were analyzed, and the fitting curve and equation were derived via fitting analysis. The magnetic field simulation results showed that sealing pressure decreased with an increase in the sealing gap, increased with the number of pole teeth, and increased and then decreased with an increase in the pole teeth angle. The trapezoidal pole teeth exhibited the best sealing performance. The experimental results showed that the best sealing performance was achieved when the amount of magnetic fluid was 3mL. The sealing pressure significantly decreased with an increase in the rotational speed.
