Abstract

To ensure the reliability of the pressure resistance and the good sealing effect, it is necessary to put forward different degrees of roughness requirements for each contact surface. One end of the two end faces of the pole piece is in contact with the shell and the "O" rubber ring sealing ring, so the roughness requirement is lower, and 3.2 is enough. The other end face is in contact with the permanent magnet, so the roughness is required to reach 1.6. At the same time, perpendicularity requirements are put forward for both surfaces. The main components of the device are designed with a split structure to facilitate processing and installation, but at the same time, higher requirements on the processing techniques are required, and the precision in the assembly process is improved. The pole shoe is a key component of the magnetic liquid rotary seal device, and it is very important for its processing. In the assembly process, the split-type magnetic liquid rotary seal device first connects the split-type parts with bolts to ensure the roundness requirements.
