Isbeddellada horumarka muhiimka ah ee foornada jawiga vacuum
Isbeddelka horumarka muhiimka ah ee foornada jawiga vacuum
Isbeddelka horumarinta tignoolajiyada daaweynta kulaylka aan oksaydhisku ka yarayn, horumarinta foornada jawiga vacuum waa mid degdeg ah. In kala duwan ee hadda yar iyo wax soo saarka mass, gaar ahaan deminaya dhalaalaya, annealing, carburizing quenching, carbonitriding quenching, iyo nitrocarburizing gaaska ee birta kaarboon iyo guud ahaan daawaha dhismaha qaybaha steel weli inta badan ku salaysan codsiga of jawi la xakamayn karo. Sidaa darteed, daaweynta kuleylka foornada jawiga ayaa weli ah qaybta ugu muhiimsan ee tiknoolajiyada daaweynta kulaylka sare.
Ilaha gaaska ee jawiga diyaarinta. Geedi-socodka maaraynta iyo horumarinta jawiga la xakamayn karo, waddankeenu wuxuu u soo maray waddo dheer oo lagu xallinayo dhibaatada jawiga. Soosaarayaasha jawiga endothermic hore waxay inta badan isticmaali jireen gaasta dareeraha ah, taas oo ah, propane ama butane oo leh nadiif sare. Sanadihii la soo dhaafay, waxaa la xaqiijiyay in kheyraadka badan ee gaaska dabiiciga ah ee dalkaygu uu abuuray xaalado wanaagsan oo loogu talagalay diyaarinta jawiga endotermic ee methane. Isticmaalka jawiga jiilka tooska ah ee aan foornada ceeriin sidoo kale waa hab aan la iska indho tiri karin.
Qalabka kuleylinta foornada jawiga vacuum. Foornada ujeedooyinka badan ee xiran iyo khadka wax-soo-saarka foornada ee ujeedooyinka badan ayaa leh heer sare oo otomaatig ah, dabacsanaan wax-soo-saarka weyn iyo ku-dhaqanka xooggan, sidaas darteed si ballaaran ayaa loo isticmaalaa.
Qallooca yar ee workpiece waa faa’iido aad u muhiim ah oo foornada jawi vacuum. Marka loo eego waayo-aragnimada gudaha iyo dibedda, qalloocinta foornada jawiga ayaa ah kaliya saddex meelood meel meel ka mid ah kuleylka qubeyska milixda iyo deminta. Waa muhiim in la barto hababka kuleyliyaha faakuumka agabyada kala duwan iyo qaybo leh heerar kala duwanaansho kala duwan iyo sharciyada qallooca ee hoos yimaada xaaladaha qaboojinta ee kala duwan, iyo in lagu sawiro kombuyuutar, taas oo muhiimad weyn u leh horumarinta tignoolajiyada foornada hawada ee vacuum . Isku mid ahaanshaha socodka hawada inta lagu jiro kuleylka faakuumka, cadaadiska caadiga ah ama daminta hawada cadaadiska sare ayaa saameyn weyn ku leh saameynta deminta iyo kala firdhinta tayada qaybaha. Isticmaalka hababka jilitaanka kumbuyuutarka si loo barto sharciga wareegga hawada ee foornada ayaa muhiimad weyn u leh hagaajinta isbeddellada qaabdhismeedka foornada. Vacuum carburization waa dariiqo suurtagal ah oo lagu gaaro karborid heerkul sare ah.
Si kastaba ha noqotee, kuleyliyaha waqti dheer heerkulka sare wuxuu ka dhigi doonaa cabbirka hadhuudhka Austenite ee inta badan birta u koraan mid aad u weyn. Carburization heerkulka sare ee birta gaar ah, saamaynta dib u kululaynta iyo deminta sifooyinka alaabta iyo workpieces ayaa la baran doonaa, iyo hagaajinta ee vacuum infiltration waa la baran doonaa. Kaarboon, qaboojin, kuleyliyaha iyo daminta hababka iyo qalabka ayaa lagama maarmaan ah. Sanadihii la soo dhaafay, waxaa jiray cilmi baaris caalami ah iyo horumarinta foornooyinka faakuumka ee nooca gubashada iyadoo la isticmaalayo shidaalka gaaska. Aad bay u adagtahay in la isticmaalo shidaalka gaaska si loogu kululeeyo foornada jawiga vacuum. Inkasta oo uu jiro odhaah ku saabsan badbaadinta tamarta, ma aha daruuri jihada horumarineed ee muhiimka ah.
