OK seal seal type sealing means to prevent leakage at the shaft and housing and set the seal types are commonly used packing seals, mechanical seal and dynamic seal. 1. packing, the structure is simple, cheap, easy to maintain, but the leakage volume, large power loss, more general media are sealed for low or reciprocating pumps. The basic structure of the turbomolecular pump is such a "trap", causing gas molecules from different sides by its transmission probability, so that the gas molecules can accumulate in the smaller one of the transmission probability, a pressure difference. Any means to make gas from low pressure to high pressure flows can form a suction effect, turbo-molecular pump is to rely on structural differences on both sides of the transmission probability of generating a pumping capacity.
