    摘要: Provided is a vacuum pump that prevents the solidification of gas while being operated properly. The vacuum pump includes a rotor that is supported rotatably on a base, a stator that has a thread groove portion, and a heating structure that heats the stator. The heating structure has a spacer that insulates the stator from stator components other than the stator, and a cartridge heater that heats the stator. The distance between a rotor cylindrical portion and the stator at the inlet port side is set to be equal to or greater than the distance between the rotor cylindrical portion and the stator at the outlet port side.

    摘要: An object is to provide a vacuum pump that enables, without being affected by a flow rate of gas to be discharged, concentrated and efficient heating of only a stator component of an exhaust side gas channel that needs to be heated in order to prevent deposition of products and that also enables prevention of deposition of products in the exhaust side gas channel as a result of the heating, and improvement of pump emission performance. The vacuum pump has a rotor rotatably arranged on a pump base and a gas channel through which gas sucked by rotation of the gas is guided to an outlet port, and further includes heat insulating means for thermally insulating a stator component, which forms an exhaust side gas channel in the gas channel, from other components and heating means for heating the thermally insulated stator component.

    摘要: The invention relates to a vacuum pump comprising a rotor shaft (10), which bears one or more rotor elements (20, 22). The rotor shaft (10) is driven by an electrical driving device (30). A stator device (24) is arranged between the rotor elements (20, 22). The rotor shaft (10) is supported by bearings (32). The highly heat-generating components such as the driving device (30) and the stator device (24) are connected to a second housing part (28) in particular by means of a support part (36). Heat-sensitive components such as the bearing (32) are supported by means of a separate first housing part (34). The two housing parts can be kept at different temperatures, for example by means of separate cooling devices. Thus, the operating temperature of the in particular pressure-side bearing (32) can be reduced, and therefore the service life can be extended.
