The model utility content
The utility model purpose is to provide a kind of external heating type titanium base getter pump that is used for Hydrogen Atom Frequency Standard, solves present sputter ion pump system bulk, weight is big, the problem that gettering rate and getter capacity are limited.
A kind of external heating type titanium base getter pump that is used for Hydrogen Atom Frequency Standard comprises: getter sheet, tungsten copper rod, nut, loam cake, urceolus, wire-mesh screen, pipeline, flange, bottom.
Urceolus and bottom welding are fixing, and there is internal threaded column the center of bottom, and there is outside thread at tungsten copper rod two ends, and tungsten copper rod lower end and bottom internal threaded column screw thread are fixed.The getter sheet is the titan-based alloy circular ring plate of thick 3mm～5mm, and getter sheet external diameter is less than the urceolus internal diameter, and the tungsten copper rod places the getter sheet annulus mesopore of a plurality of stacks, and the getter sheet is 15～30.Wire-mesh screen is the round metal ring plate, and the wire-mesh screen external diameter is identical with the internal diameter of urceolus, and wire-mesh screen places getter sheet upper end.Nut and tungsten copper rod upper end screw thread are fixed, and place on the wire-mesh screen.The welding of loam cake and urceolus is fixing, on be stamped a through hole, pipeline is a metallic cylinder, internal diameter of the pipeline is identical with the loam cake through-hole diameter, pipeline welds with loam cake and fixes.Flange center's bore dia is identical with internal diameter of the pipeline, and flange and pipeline welding are fixed.
Titanium base getter pump is with after the Hydrogen Atom Frequency Standard device is connected, the heating urceolus, heat passes on getter sheet and the tungsten copper rod, at the fixed time after, cooling activates and finishes.Titanium base getter pump is started working, the working gas hydrogen of Hydrogen Atom Frequency Standard device spreads in surface adsorption, top layer infiltration, body and combines with the getter sheet, reactive gas in the getter sheet hydrogen ion adsorption frequency marking device is kept the vacuum state of Hydrogen Atom Frequency Standard device.
The utility model adopts titanium base getter sheet, by cooperating a small-sized titanium sputter ion pump, under the condition of long-time running, well keeps Hydrogen Atom Frequency Standard device vacuum.The utility model volume is little, in light weight, pumping speed is big and stable, and getter capacity is big, helps increasing the service life, and is fit to produce in enormous quantities, can reduce cost, and can guarantee quality of product again.
