| Abstract: | The new types of seal for special demands of coal high-speed liquefaction e- quipment are introduced. These new types of seal are no-gasket line-contact seal, screw sleeve semi-self-sealing seal and magnetic driving seal. The process of design of these seals is explained. Magnetic driving seal can turn rotational seal into static seal, and no-leakage can be realized. No- gasket line-contact seal and screw sleeve semi-self-sealing seal have advantages: reliable sealing, assembling and disassemble and repair simply. |
