Iimpawu kunye nezicelo

Ipompo ye-NEG luhlobo lwempompo ye-chemisorption, ehlanganiswe emva kwe-alloy ye-NEG ifudunyezwe yi-sintering ephezulu, inokuphelisa inani elikhulu leegesi ezishiyekileyo kwindawo yokucoca, ngokukodwa isetyenziselwa ukuvavanywa kwe-UHV okanye izixhobo zeLebhu. Xa ivuliwe iimpompo ze-NEG zinokusebenza ngaphandle kwamandla, nazo azinaVibration kunye neNonmagnetic. Eyona nto iphambili kwiimpompo ze-NEG iyasebenza kakhulu kwiHydrogen kunye nezinye iigesi ezisebenzayo, kwaye ayinakuze yehlise phantsi kwe-UHV.

Iimeko zokuvula ezicetyiswayo

Kucetyiswa ukuba umsebenzisi asebenzise unikezelo lwamandla lwangoku rhoqo ukunika amandla kunye nokuvula i-NEG Pump. Iimeko zokuvuselela ezicetyiswayo: Ukuvuselela amandla kwi-450 ° C kwi-45min, i-vacuum degree yenkqubo kuyo yonke inkqubo yokuqalisa kufuneka ibe ngcono kune-0.01Pa. Ukwandiswa okufanelekileyo kwexesha kuya kuququzelela ukusebenza ngokupheleleyo kwePump ye-NEG. Ukuba ubushushu obuqhelekileyo bokusebenza alinakufikelelwa, ixesha lokuvula kufuneka landiswe ukuze lihlawule. Kuyimfuneko ukuqinisekisa iqondo lokufunxa lwegumbi lokufunxa ngexesha lenkqubo yokuvula, ukuba ngaba ivacuum iphantsi kakhulu, ezi ziphene zilandelayo zingenzeka: ukutshiza kwesifudumezi, ungcoliseko lwezinto ezifunxayo, ubushushu obungaqhelekanga bokuvula kunye nezinye iimeko ezimbi.

I-NEG Pump ikhupha isixa esithile seegesi ngexesha lokusebenza, ukuze kuqinisekiswe idigri yevacuum ngexesha lokuvula i-NEG Pump. Sincoma ukuba iPump ye-NEG kufuneka isebenze phantsi kwe-vacuum eguquguqukayo, kwaye inkqubo yokuvula kufuneka ihambe ngokucotha kwaye inyuke ngokuthe ngcembe ukusuka kwi-1.5A de kufikelelwe kwixabiso elimiselweyo langoku, ukuchithwa ngokukhawuleza kunye nokutshintsha kweeparamitha zombane ezibangelwa utshintsho olukhawulezayo lombane. ubushushu bePump ye-NEG kufuneka buphetshwe.

Isilumkiso

Xa ivuliwe kwaye isebenza, i-NEG Pump casing kunye ne-flange inokushisa okuphezulu, qaphela ukukhusela ukutshisa.

Xa i-NEG Pump ikwiqondo lokushisa eliphezulu, kufuneka ibe kwiimeko ze-vacuum ukuphepha ukungaphumeleli ngenxa yokungcola kunye nokusetyenziswa.

Xa udibanisa ukunikezelwa kwamandla, qinisekisa ukuba uxhulumaniso phakathi kombane kunye ne-electrode ye-flange iqinile, kwaye ubeke ingqalelo kwi-insulation kunye nezinye iindawo.

Ngaphambi kokufudumeza kusebenze, qaphela ukuqinisekisa ukuba inkqubo iphantsi kweemeko ze-vacuum ezihlangabezana neemfuno.

Ngaphantsi kweemeko ezikhethekileyo, ukwenzela ukuba i-NEG Pump ibe nesantya esiphezulu sokupompa i-C, N, O kunye nezinye iigesi, ubushushu bokusebenza bunokugcinwa kwi-200 °C ~ 250 °C (energized 2.5A), kwi kule meko elona qondo liphezulu le-vacuum enokufikelela kwi-NEG Pump liyancitshiswa.
