NEG pombi imhando yepombi ye chemisorption, iyo yakaungana mushure meiyo NEG alloy inopisa nepamusoro sintering, Inogona kubvisa huwandu hukuru hwemagasi akasara munzvimbo yevacuum, inonyanya kuisirwa kuongororwa kweUHV kana Lab michina. Kana yaitwa NEG pombi inogona kushanda isina simba, zvakare isina Vibration uye Nonmagnetic. Iyo yakasarudzika yemapombi eNEG inoshanda zvakanyanya kuHydrogen uye mamwe magasi anoshanda, uye haizombodzikisire pasi peUHV.

Inokurudzirwa activation conditions

Zvinokurudzirwa kuti mushandisi ashandise anogara aripo emagetsi ekupa simba uye kumisa iyo NEG Pombi. Yakakurudzirwa activation mamiriro: Energizing activation pa 450 ° C ye 45min, iyo vacuum degree yehurongwa mukuita kwese kwekuita kunofanirwa kunge kuri nani pane 0.01Pa. Kuwedzerwa kwakaringana kwenguva kunofambisa kuzara kweiyo NEG Pump. Kana iyo yakajairwa activation tembiricha isingasvikike, iyo activation nguva inofanirwa kuwedzerwa kutsiva. Izvo zvinodiwa kuti uve nechokwadi chevacuum degree yevacuum chamber panguva ye activation process, kana vacuum yacho yakadzikira, zvinotevera zvinokanganisa zvinogona kuitika: sputtering yeheater, suction material pollution, abnormal activation tembiricha nemamwe mamiriro asina kunaka.

Iyo NEG Pombi inoburitsa imwe huwandu hwemagasi panguva ye activation, kuitira kuti ive nechokwadi chevacuum degree panguva yekushandiswa kweNEG Pombi. Isu tinokurudzira kuti iyo NEG Pombi inofanirwa kuisirwa pasi pesimba dhizaini, uye iyo activation process inofanirwa kuwedzera zvishoma nezvishoma uye zvishoma nezvishoma kubva ku1.5A kusvika iyo yakafanotemerwa kukosha ikozvino yasvika, kukurumidza deflation uye shanduko yemagetsi parameter inokonzerwa nekukurumidza shanduko ye tembiricha yeNEG Pombi inofanira kudzivirirwa.

Kuchenjerera

Kana yaitwa uye ichishanda, iyo NEG Pombi casing uye flange ine tembiricha yakanyanya, teerera kudzivirira kupisa.

Kana iyo NEG Pombi iri pakupisa kwepamusoro, inofanirwa kunge iri munzvimbo dzevacuum kudzivirira kutadza nekuda kwekusvibiswa uye kushandiswa.

Paunenge uchibatanidza magetsi, iva nechokwadi chokuti kuwirirana pakati pemagetsi uye flange electrode yakasimba, uye teerera kune insulation nezvimwe zvikamu.

Usati wapisa activation, teerera kuti uve nechokwadi chekuti system iri pasi pevacuum mamiriro anosangana nezvinodiwa.

Mumamiriro ezvinhu akakosha, kuitira kuti NEG Pombi ive nekumhanya kukuru kwekupomba kweC, N, O nemamwe magasi, tembiricha yekushanda inogona kuchengetedzwa mumhando ye200 °C ~ 250 °C (energized 2.5A), mukati panguva iyi dhigirii rekupedzisira vacuum rinogona kuwanikwa neNEG Pump rakadzikiswa.
