Iphampu ye-NEG iwuhlobo lwephampu ye-chemisorption, eyahlangana ngemva kwengxubevange ye-NEG yashisisa i-sintering ephezulu, Ingaqeda inani elikhulu lamagesi ayinsalela endaweni ye-vacuum, ikakhulukazi esetshenziselwa ukuhlolwa kwe-UHV noma okokusebenza kwe-Lab. Uma icushiwe amaphampu e-NEG angasebenza ngaphandle kwamandla, futhi ngaphandle kokudlidliza kanye ne-Nonmagnetic. Okugqamile kwamaphampu e-NEG kusebenza ngokwedlulele kuHydrogen namanye amagesi asebenzayo, futhi akusoze kwancipha ngaphansi kwe-UHV.

Izimo zokuvula ezinconyiwe

Kunconywa ukuthi umsebenzisi asebenzise amandla amanje angashintshi ukuze anikeze amandla futhi enze i-NEG Pump isebenze. Izimo zokuvula ezinconyiwe: Ukwenza kusebenze okunika amandla ku-450°C imizuzu engu-45, idigri ye-vacuum yesistimu kuyo yonke inqubo yokwenza kusebenze kufanele ibe ngcono kuno-0.01Pa. Ukunwetshwa okufanele kwesikhathi kuzokwenza kusebenze ngokugcwele i-NEG Pump. Uma izinga lokushisa elijwayelekile lokuvula lingenakufinyelelwa, isikhathi sokwenza kusebenze kufanele sinwetshwe ukuze kunxeshezelwe. Kudingeka ukuqinisekisa izinga le-vacuum yegumbi le-vacuum ngesikhathi senqubo yokwenza kusebenze, uma i-vacuum iphansi kakhulu, kungase kwenzeke izinkinga ezilandelayo: ukuphalaza kwe-heater, ukungcoliswa kwezinto ezimuncwayo, izinga lokushisa elingavamile lokuvula nezinye izimo ezimbi.

I-NEG Pump ikhipha inani elithile lamagesi phakathi nokusebenza, ukuze kuqinisekiswe idigri ye-vacuum phakathi nokusebenza kwe-NEG Pump. Sincoma ukuthi i-NEG Pump kufanele icushwe ngaphansi kwe-vacuum eguqukayo, futhi inqubo yokuvula kufanele ihambe kancane futhi kancane kancane inyuke isuka ku-1.5A kuze kufinyelelwe inani lamanje elinqunyelwe kusengaphambili, ukwehla kwamandla emali ngokushesha kanye nokushintshwa kwamapharamitha kagesi okubangelwa ukushintsha okusheshayo izinga lokushisa le-NEG Pump kufanele ligwenywe.

Isexwayiso

Uma icushiwe futhi isebenza, i-NEG Pump casing kanye ne-flange inezinga lokushisa eliphezulu, qaphela ukuvimbela ukusha.

Uma i-NEG Pump isezingeni lokushisa eliphezulu, kufanele ibe sesimweni esingenalutho ukuze igweme ukwehluleka ngenxa yokungcoliswa nokusetshenziswa.

Uma uxhuma ukunikezwa kwamandla, qinisekisa ukuthi ukuxhumana phakathi kwamandla kagesi kanye ne-electrode ye-flange kuqinile, futhi unake ukufakwa kwezinye izingxenye.

Ngaphambi kokwenza kusebenze ukushisisa, qaphela ukuze uqinisekise ukuthi uhlelo lungaphansi kwezimo ze-vacuum ezihlangabezana nezidingo.

Ngaphansi kwezimo ezikhethekile, ukuze kwenziwe i-NEG Pump ibe nesivinini esikhulu sokumpompa i-C, N, O namanye amagesi, izinga lokushisa elisebenzayo lingagcinwa ku-200 °C ~ 250 °C (energized 2.5A), kulokhu idigri yokugcina ye-vacuum engafinyelelwa yi-NEG Pump iyancishiswa.
