Molecular vacuum pump was first invented by the German Gerd (w · Gaede) in 1911, and elaborated the theory of pumping of the molecular pump, making the mechanical vacuum pump have a new breakthrough in the pumping mechanism. Molecular pump pumping mechanism and volumetric mechanical pump pumping chamber volume change of the pumping mechanism is different from the molecular flow in the molecular flow region by the high-speed motion of the rigid body surface to the gas molecules to momentum, the gas molecules in the rigid body surface Of the direction of the movement generated directional flow, so as to achieve the purpose of pumping. Usually the high-speed movement of rigid body surface carrying gas molecules, and make it move in a certain direction is called the phenomenon of molecular traction. Therefore, people will Gade invented the molecular pump called traction molecular pump.
