Theauto darkening welding helmet ingowani inodzivirira inogadzirwa nemisimboti senge optoelectronics, mota, uye photomagnetism.Germany yakatanga kushambadza DZN4647T.7 yemagetsi yakavharwa nekavha yewindow uye magirazi mwero muna Gumiguru 1982, uye chiyero cheBS679 chakaburitswa neUnited Kingdom muna 1989 chinotsanangura nguva iyo nhovo yemwenje inoshanduka kubva pachiedza ichienda kune rima panguva yewelding.China yakatanga kugadzira photoelectric otomatiki ruvara-inochinja welding inodzivirira ngowani mukutanga kwema1990s.
Kutanga, chimiro chinoumbwa nezvikamu zviviri: muviri mukuru wengowani uye chiedza chekuchinja system.Muviri mukuru wengowani wakaiswa musoro, une murazvo unodzoreredza ABS jekiseni kuumba, huremu, hunogara, hunogona kugadziridzwa kubva muzvikamu zvitatu zvakasiyana, hunogona kuenderana nemhando dzakasiyana dzemusoro.Iyo yemwenje sisitimu inosanganisira mwenje sensor, control circuitry, liquid crystal light valve, uye sefa.
Chechipiri, musimboti wekudzivirira, Iyo yakasimba arc radiation inogadzirwa panguva yewelding inotorwa neiyo mwenje sensor, ichikonzeresa dunhu rekutonga, uye inobuda inoshanda voltage yedunhu rekutonga inowedzerwa kune liquid crystal light valve, uye liquid crystal light valve. kuchinja kubva kumamiriro akajeka kusvika kune opaque pasi pechiito chemunda wemagetsi, uye ultraviolet transmittance yakaderera zvikuru.Chikamu chechiedza che infrared kuburikidza neiyo liquid crystal light valve inotorwa neimwe sefa.Kamwe mwenje wearc wadzimwa, sensor yemwenje haichabudisi chiratidzo, dunhu rekutonga harichabudisi magetsi ekushanda, uye iyo liquid crystal light valve inodzokera kune yakajeka mamiriro.
Chechitatu, izvo zvakakosha zvehunyanzvi zvinodiwa:1. saizi: iyo inoshanda yekutarisa saizi haizove isingasviki 90mm × 40mm.2.Photogen performance: shading number, ultraviolet/ infrared transmission ratio, parallelism inofanira kuenderana nezvinodiwa zveGB3690.1-83.3.Kuita kwesimba: Iwindo rekutarisa rinofanirwa kukanganiswa katatu pasina kukuvara kwekamuri tembiricha ine 45 magiramu emabhora esimbi anodonha zvakasununguka kubva paurefu hwe0.6m.4.Nguva yekupindura ichaenderana nemirairo yakakodzera.
Chechina, Chengetedzo yekushandiswa:1.Auto darkening welding helmete yakakodzera kune ese mawebhusaiti ebasa rekuisa, pane akabatwa ruoko uye akaiswa musoro zvigadzirwa zviviri.2.Kana magirazi aita seanopenya kana kusviba kana ari mumamiriro akajeka, bhatiri rinofanira kutsiviwa.3.Dzivirira kudonha kwakanyanya uye kumanikidza kunorema, kudzivirira zvinhu zvakaoma kubva pakukwesha lenzi nengowani.
