摘要：

The stability and durability of magnetic liquid seals have been tested under the condition of sealing other liquids. The results show that the deterioration of the magnetic fluid depends on the nature and combination of magnetic and nonmagnetic liquids as well as on the shaft speed, the temperature of the seal and the gradient of the magnetic field. Seal life is considerably extended by suitabily shielding the magnetic fluid ring against the liquid to be sealed. © 1990.
