fasahar defishing cryogenic An fara ƙirƙira a cikin 1950s.A cikin ci gaban tsarin na'urorin defishing na cryogenic, ya wuce ta lokuta uku masu mahimmanci.Bi tare a cikin wannan labarin don samun cikakkiyar fahimta.
(1) Na'urar lalatar da ake kira cryogenic
Ana amfani da drum ɗin daskararre azaman kwantena mai aiki don daskararre gefuna, kuma busasshen ƙanƙara an fara zaɓe a matsayin mai sanyaya.An ɗora sassan da za a gyara a cikin ganga, mai yiwuwa tare da ƙarin wasu kafofin watsa labaru masu cin karo da juna.Ana sarrafa zafin jiki a cikin ganga don isa ga yanayin da gefuna suka yi rauni yayin da samfurin kansa ya kasance ba ya shafa.Don cimma wannan burin, kauri daga cikin gefuna ya kamata ya zama ≤0.15mm.Ganga shine farkon ɓangaren kayan aiki kuma yana da siffar octagonal.Makullin shine don sarrafa tasirin tasirin kafofin watsa labarai da aka fitar, yana ba da damar zazzagewa ya faru akai-akai.
Drum ɗin yana jujjuya sa'o'i a kusa da agogo don faɗuwa, kuma bayan ɗan lokaci, gefuna na walƙiya sun zama masu karye kuma an kammala aikin.Lalacewar tsararkin daskararre na ƙarni na farko bai cika ba, musamman saura gefuna na walƙiya a ƙarshen layin rabuwa.Ana haifar da wannan ta rashin isassun ƙirar ƙira ko kauri da yawa na layin roba a layin rabuwa (fiye da 0.2mm).
(2) Na'ura mai kashewa ta cryogenic
Na'ura mai lalata cryogenic na biyu ya yi gyare-gyare uku bisa ga ƙarni na farko.Na farko, an canza refrigerant zuwa ruwa nitrogen.Busasshen ƙanƙara, tare da madaidaicin madaidaicin -78.5°C, bai dace da wasu rubbers masu ƙarancin zafin jiki ba, kamar roba na silicone.Liquid nitrogen, tare da wurin tafasa na -195.8 ° C, ya dace da kowane nau'in roba.Na biyu, an yi gyare-gyare ga kwandon da ke ɗauke da sassan da za a gyara.Ana canza shi daga ganga mai jujjuya zuwa bel mai siffa mai siffa a matsayin mai ɗaukar kaya.Wannan yana ba da damar sassan su tumbura a cikin tsagi, da rage yawan abin da ya faru na matattu.Wannan ba kawai inganta inganci ba har ma yana haɓaka madaidaicin edging.Na uku, maimakon dogaro kawai da karon da ke tsakanin sassan don cire gefuna na walƙiya, an ƙaddamar da kafofin watsa labarai masu kyau.Karfe ko wuya filastik pellets tare da barbashi size of 0.5 ~ 2mm ana harbi a saman sassa a mikakke gudun 2555m / s, haifar da wani gagarumin tasiri karfi.Wannan haɓakawa yana rage girman lokacin zagayowar.
(3) Na'ura mai kashewa ta cryogenic
Na'ura mai lalata cryogenic na uku shine haɓakawa dangane da ƙarni na biyu.Ana canza akwati don sassan da za a gyara zuwa kwandon sassa tare da bango mai raɗaɗi.Wadannan ramukan suna rufe bangon kwandon tare da diamita na kusan 5mm (mafi girma fiye da diamita na projectiles) don ba da damar ma'auni su wuce ta cikin ramukan lafiya kuma su koma saman kayan aiki don sake amfani da su.Wannan ba kawai yana faɗaɗa ƙarfin ƙarfin akwati ba amma har ma yana rage girman ajiya na kafofin watsa labarai masu tasiri (projectiles) .Ba a sanya kwandon sassan a tsaye a cikin injin datsa ba, amma yana da wani sha'awa (40 ° ~ 60 °).Wannan kusurwar karkata yana sa kwandon ya yi ƙarfi yayin aikin ƙetare saboda haɗuwa da ƙarfi guda biyu: ɗaya shine ƙarfin jujjuyawar da kwandon da kansa ke bayarwa, ɗayan kuma ƙarfin centrifugal ne wanda tasirin tsinkaya ya haifar.Lokacin da aka haɗa waɗannan runduna guda biyu, motsi na 360° na gaba ɗaya yana faruwa, yana barin sassan su cire gefuna masu walƙiya iri ɗaya kuma gaba ɗaya a duk kwatance.
