在密封其它液体的条件下，对磁性液体密封的稳定性和耐久性进行了试验。结果表明，磁流体的劣化程度与磁流体和非磁流体的性质和组合有关，也与轴转速、密封温度和磁场梯度有关。通过适当地屏蔽磁性流体环以防止被密封的液体，密封寿命显著延长。
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.
