| Abstract: | In order to solve the problems that exit in the magnetic fluid sealing of reciprocating shaft, the magnetic fluid flow in the seal gap was studied when the reciprocating shaft moves with different velocities and strokes. The follwing were focused on the regular pattern of such flow, the loss quantity of magnetic fluid caused by the reciprocating motion shaft, the failure reasons of this magnetic fluid sealing and the design of a new structure for the magnetic fluid sealing of reciprocating shaft. The application indicates that the new structure is very effective in some occasions. |
| Keywords: | sealing reciprocating mechanisms magnetism fluid |
