Pompe ya NEG ni ubwoko bwa pompe ya chemisorption, yateranije nyuma yumusemburo wa NEG ushyutswe no gucumura cyane, Irashobora gukuraho imyuka myinshi isigara ahantu hatuje, cyane cyane ikoreshwa mubizamini bya UHV cyangwa ibikoresho bya Laboratoire. Iyo ikora pompe ya NEG irashobora gukora idafite ingufu, nayo idafite Vibration na Nonmagnetic. Ikintu cyaranze pompe ya NEG ni ingirakamaro cyane kuri Hydrogene nizindi myuka ikora, kandi ntizigera igabanuka munsi ya UHV.

Basabwe gukora ibikorwa

Birasabwa ko uyikoresha akoresha amashanyarazi ahoraho kugirango atange ingufu kandi akore pompe ya NEG. Icyifuzo gisabwa cyo gukora: Gutera imbaraga kuri 450 ° C kuri 45min, impamyabumenyi ya vacuum ya sisitemu mubikorwa byose byo gukora igomba kuba nziza kuruta 0.01Pa. Kwagura neza igihe bizorohereza gukora byuzuye Pompe ya NEG. Niba ubushyuhe busanzwe bwo gukora budashobora kugerwaho, igihe cyo gukora kigomba kongerwa kugirango yishyure. Birakenewe kwemeza urugero rwa vacuum rwicyumba cya vacuum mugihe cyo gukora, niba icyuho ari gito cyane, hashobora kubaho inenge zikurikira: gusohora ubushyuhe, kwanduza ibintu byangiza, ubushyuhe bwibikorwa bidasanzwe nibindi bihe bibi.

Pompe ya NEG irekura gazi runaka mugihe cyo gukora, kugirango hamenyekane impamyabumenyi ya vacuum mugihe cyo gukora pompe ya NEG. Turasaba ko Pompe ya NEG igomba gukoreshwa munsi yumuvuduko ukabije, kandi ibikorwa byo gukora bigomba kugenda buhoro buhoro buhoro buhoro kuva kuri 1.5A kugeza igihe agaciro kateganijwe kugerwaho, kugabanuka byihuse no guhindura ibipimo byamashanyarazi biterwa nimpinduka zihuse za ubushyuhe bwa Pompe ya NEG bugomba kwirindwa.

Icyitonderwa

Iyo ikora kandi ikora, isanduku ya NEG Pump na flange bifite ubushyuhe bwinshi, witondere kwirinda gutwikwa.

Iyo pompe ya NEG iri ku bushyuhe bwinshi, igomba kuba mubihe byumuvu kugirango wirinde kunanirwa kubera kwanduza no kuyikoresha.

Mugihe uhuza amashanyarazi, menya neza ko isano iri hagati yumuriro wamashanyarazi na flange electrode ihamye, kandi witondere kubitandukanya nibindi bice.

Mbere yo gushyushya ibikorwa, witondere neza ko sisitemu iri mubihe byujuje ibisabwa.

Mubihe bidasanzwe, kugirango Pompe ya NEG igire umuvuduko mwinshi wo kuvoma C, N, O nizindi myuka, ubushyuhe bwakazi burashobora kugumaho hagati ya 200 ° C ~ 250 ° C (ingufu 2.5A), muri uru rubanza impamyabumenyi ihanitse ya pompe NEG ishobora kugeraho iragabanuka.
