摘要
研制了一种用于船舶艉轴磁流体密封的试验装置,研究了不同的磁饱和强度、转速及密封间隙对不同类型的磁流体密封承压能力的影响。结果表明,油基磁性流体可作为船舶艉轴密封液,对水和海水介质密封压差可以达到2MPa;船舶艉轴磁流体密封的耐压能力,随着磁流体饱和磁化强度的提高而增大,随着转轴转速的增加而减小,随着径向间隙的减小而增大。
A tester which is used to seal axes of sterns with magnetic fluid was developed.The effects of magnetic saturation intensity,sealing clearance and rotate speed on the bearing capacity of the different magnetic fluid seal were studied.The result shows that oil-based magnetic fluid can be used as sealing liquid of the sterns,and the differential pressure between sealing water and sealing seawater can reach as much as 2 MPa.With the decrease of radial clearance,bearing capacity of this seal increases,but the i...
