Turbine Cap for Turbo-Molecular Pump |
| 摘要 |
Systems here include cone shaped turbine caps mounted to a turbo molecular turbine assembly. In some embodiments, the turbo molecular turbine assembly includes a body with a top cavity, a bottom cavity and external fins, the body mounted to a pump rotor. In some embodiments, the turbo molecular turbine assembly and cone shaped turbine cap are configured to fit into a chamber and spun by the mounted pump rotor. In some embodiments, the turbine external fins are configured to pump gasses and suspended particles from the chamber when spun. And in some embodiments, the cone shaped turbine cap includes a vent channel for venting air from the top cavity. |
