| titleOfInvention | Vacuum environment manufacturing structure of quadrupole mass spectrometer |
| abstract | The utility model discloses a quadrupole mass spectrometer vacuum environment manufacturing structure, including cavity in mass spectrometer casing and the mass spectrometer, cavity inner chamber wall fixed mounting has vacuum detection device in the mass spectrometer, cavity inner chamber lower wall fixed mounting has the fixed plate in the mass spectrometer, the terminal surface is fixed mounting has first sealed sound-proof belt and data connector respectively under the fixed plate, terminal surface right side fixed mounting has the baffle under the fixed plate, baffle right-hand member wall fixed mounting has intelligent control device, open in the middle part of the baffle inner chamber has the suction slot, this quadrupole mass spectrometer vacuum environment manufacturing structure can detect the air content of cavity inner chamber in the mass spectrometer, makes the cavity reserve a small amount of gas and can be used for absorbing excessive kinetic energy; the disassembly convenience of the turbomolecular pump is improved, the turbomolecular pump is convenient to clean, the sound insulation effect of the turbomolecular pump is improved, and the noise of the turbomolecular pump is reduced. |
