Web10 de jan. de 2024 · Depending on the type and amount of particles to be extracted, regeneration may be conducted with helium at 100 K, 300 K or 500 K (-173 °C, 27 °C or 227 °C). In this way, gas particles trapped in the usually super-cold cryopump surfaces will detach from them. Research Instruments (RI) has been the main contractor in charge of … WebTurbomolecular pump. A turbomolecular pump is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. [1] [2] These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface. In a turbomolecular pump, a rapidly ...
Webcryopump: [noun] a vacuum pump whose operation involves the freezing and adsorption of gases on cold surfaces at very low temperatures. Web10 de jan. de 2024 · So we can easily understand the physics behind cryopumps. Each gas has a (saturated) vapour pressure that is a function of temperature – the higher the temperature the higher the vapour pressure.

WebThe principle of the molecular pump - well known since 1913 - is that the gas particles to be pumped receive, through impact with the rapidly moving surfaces of a rotor, an impulse in a required flow direction. The surfaces of the rotor - usually disk-shaped - form, with the stationary surfaces of a stator, intervening spaces in which the gas ...
WebDiffusion pumps consist basically (see Fig. 2.44) of a pump body (3) with a cooled wall (4) and a three, four or five-stage nozzle system (A - D).
