| Abstract: | Seal assembly of three stages (guide sleeve, shiftable seal ring unit and disc-seal) is adopted to accomplish the sealing of oil heat extraction equipment. The theory of laminar flow in the interspaces and axle end sealing is used to confirm the seal interspaces. Contacting and contactless seal methods were adopted carry out the lubricating requirement. Through this study , the expected effective seal was obtained. |
