摘要
Two kinds of new magnetic fluid sealing structures, the shaft-direction and section-direction combined sealing structure and the shaft-direction gear-adding sealing structure were designed, to meet the limit to the size of sealing equipments in practice. The decisive factors affecting on the pressure tight ability of the two kinds of new sealing structures and their regularities were studied by sealing water experiments, and the magnetic field distribution of the two kinds of new sealing structures was analyzed by ANSYS computation method. The results show that the two kinds of new sealing structures both can improve the pressure tight ability per volume of magnetic fluid sealing devices. Compared with the traditional shaft-direction sealing structure, the shaft-direction and section-direction combined sealing structure is more sensitive, so its pressure tight ability descends faster than that of the traditional shaft-direction sealing structure with the increase of the rotate speed.
