Inkasta oo qiimaha sareeyo, taangiyada kuleyliyaha birta ah guud ahaan waa kuwo aad waxtar u leh marka la barbar dhigo kharashyada wareegga nolosha waana in loo soo bandhigaa sidaas oo kale.
Kuleyliyaha biyaha guriga waa lugta dhabta ah ee adduunka farsamada. Waxay inta badan la kulmaan jawi aad u adag, shaqadooda adagna inta badan waa la iska indhatiraa. Dhinaca biyaha ee kuleyliyaha, macdanta, oksijiinta, kiimikooyinka iyo wasakhda ayaa dhamaantood la weeraray. Marka ay timaado gubasho, heerkulka sare, cadaadiska kulaylka, iyo condensate gaaska flue ayaa dhammaantood burburin kara alaabta.
Marka ay timaado dayactirka, kuleyliyeyaasha biyaha kulul ee gudaha (DHW) dhamaantood waa la dayacay. Inta badan mulkiilayaasha guryaha waxay u qaataan kuleyliyeyaasha biyaha si fudud oo kaliya waxay ogaadaan marka aysan shaqeynin ama ay daadinayaan. Hubi usha anode?
Noloshan gaaban ma la hagaajin karaa? Isticmaalka kuleyliyeyaasha DHW ee ka samaysan birta aan nadiifka ahayn waa hal dariiqo oo lagu kordhiyo rajada nolosha
Birta aan birta lahayn waa magaca guud ee alwaaxyada birta ah ee leh maadada chromium ee ugu yaraan 10.5% . Waxyaabaha kale sida nikkel, molybdenum, titanium iyo carbon sidoo kale waxaa lagu dari karaa si ay u bixiyaan iska caabin daxalka, xoog iyo formability.There waxaa jira badan oo isku darka badan oo kala duwan oo ka mid ah Alloys biraha kala duwan in ay soo saaraan gaar ah "noocyo" iyo "derajooyinka" ee ah birta ah oo dhan ma sheego wax birta ah oo dhan.
Haddii qof yidhaahdo "isii qaar ka mid ah tuubooyinka caaga ah" maxaad keeni lahayd? PEX, CPVC, polyetylen? Dhammaan kuwan waa "caag" tuubooyinka, laakiin dhammaantood waxay leeyihiin sifooyin aad u kala duwan, xoog iyo codsiyada. Isla sidaas u socotaa ahama steel.There are in ka badan 150 fasalada ahama, oo dhan oo leh hanti aad u kala duwan iyo codsiyada 316Ti iyo 444.
Farqiga u dhexeeya darajooyinkaas waa fiirsashada daawaha ee ku jira. Dhammaan "300" biraha aan la taaban karin waxay ka kooban yihiin qiyaastii 18% chromium iyo 10% nikkel. Labada 316 ee darajada ayaa sidoo kale ka kooban 2% molybdenum, halka darajada 316Ti uu leeyahay 1% titanium lagu daray isku dhafka. Marka la barbardhigo 304 molybdenum, molybdenum guud ahaan, molybdenum. iska caabinta sare ee pitting and cevice corrosion in chloride jawi darajooyinka maadaama aysan isku tayo ahayn
Kuleyliyaha biyaha aan tooska ahayn waxaa loo isticmaalaa dhammaan noocyada kala duwan ee kuleyliyeyaasha biyaha.Waxay inta badan loo isticmaalaa kuleyliyeyaasha aan tooska ahayn ee DHW iyo kuleyliyeyaasha biyaha aan taangi lahayn.
Kuleyliyaha birta ah ee aan qaboojinayn waxa uu ka samaysan yahay copper Birta kaarboon ee leh dahaarka dhalada ayaa ka taliya qaybtan
Si loo kordhiyo waxtarka qalabkan, gaaska qiiqa waa in lagu qaboojiyaa meel ka hooseysa barta sayaxa si loo sii daayo kulaylka qarsoon ee shidaalka
Beddelayaasha kulaylka ee ka samaysan birta caadiga ah ama naxaasta way adag tahay in ay u adkeystaan ​​condensate gaaska flue muddo dheer. Birta aan lahayn waa doorasho shay wanaagsan sababtoo ah caabbinta daxalka sare iyo dabacsanaanta, taas oo u oggolaanaysa in ay sameeyaan qaababka kuleylka kuleylka adag ee qaababka 0.97.
Kuleyliyaha biyaha taangiga ah ee tignoolajiyada qaboojinta ayaa sidoo kale hadda bilaabay in la isticmaalo si joogto ah, gaar ahaan qaar ka mid ah isbeddelada koodhka dhismaha ee u baahan waxtarka kululeeyaha biyaha sare. Waxaa jira laba nooc oo dhismo ah oo caadi ah suuqan Taangiga birta aan-daawaynta lahayn iyo dhismaha gariiradda ma aha wax caadi ah, laakiin waxaa jira dhowr dhismo oo bir ah oo aan-taxan lahayn oo la heli karo.
Qiimaha bilowga ah ee taangiga muraayadda ah ayaa runtii ka hooseeya, kaliyana wakhtiga ayaa sheegi doona sida ay u adkaysanayso kulaylka kuleylku uu noqon doono jawi adag oo adag. Kuwan cusub ee kuleyliyeyaasha biyaha kondensate waxay awoodaan in ay gaaraan waxtarka sare marka loo eego kuleyliyeyaasha tooska ah ee caadiga ah, oo leh waxtarka kulaylka oo u dhexeeya 90% ilaa 96% . suuqa gal.
U fiirso kuleyliyaha biyaha taangiga waxaadna ogaan doontaa in badi noocyada ugu badan ee tooska ah ee dabka lagu shido, gariiradda gudaha aan tooska ahayn, iyo taangiyada kaydinta tooska ah ay leeyihiin dhismo bir ah oo ka samaysan muraayado iyo bir aan daahin.
Sidaa darteed, waa maxay faa'iidooyinka birta birta ah ee ka badan muraayadaha? Sidee ayaad ugu qancin kartaa macaamiisha inay maalgashadaan wax badan oo ku jira taangiyada birta ah ee birta ah? Faa'iidada ugu weyn ee birta birta ah waa iska caabbinta dabiiciga ah ee daxalka biyaha nadiifka ah, taas oo kordhisa adeegga nolosha
Taangiyada muraayadaha leh, dhinaca kale, waxay ku tiirsan yihiin muraayadaha muraayadda si ay u bixiyaan xannibaad u dhexeeya birta kaarboonka iyo biyaha. Marka la eego fursadda, oksijiinta iyo kiimikooyinka biyaha ayaa weerari doona birta oo si degdeg ah u daxalisay. Tan iyo markii ay ku dhowdahay wax aan macquul ahayn in la daboolo wax kasta oo ilaalin ah oo qumman (ma jiraan dildilaaca microscopic ama cilladaha pinhole ee lakabka ilaalinta) Taangiyada muraayadda leh ee lagu dhejiyay gudaha sacrifiska.
Ulaha anode-ka allabarigu waxay daalan doonaan waqti ka dib, marka habka la dhammeeyo, electrolysis wuxuu bilaabi doonaa inuu baabi'iyo meelaha birta ah ee bannaan ee gudaha taangiga. Heerka uu ku dhaco anode wuxuu ku xiran yahay tayada biyaha iyo qiyaasta biyaha ee loo isticmaalo.
Dhab ahaantii, kormeerka joogtada ah iyo beddelka anodes-ka ayaa inta badan la iska indhatiraa, taangigana wuu daadanayaa, taas oo keenaysa in la beddelo qaybta oo dhan.
Sababtoo ah adkaysigan korodhay iyo iska caabbinta daxalka, waxa aad inta badan ka heli doontaa taangiyada birta ah oo leh dammaanad dheer, iyada oo qaar ka mid ah warshaduhu ay bixiyaan dammaanad nololeed oo taangiyada ah.
Taangiyada birta ah ee birta ah ayaa sidoo kale faa'iido u leh inay noqdaan kuwo fudud marka loo eego taangiyada muraayadaha, taas oo u sahlaysa in la qaado, la qabsado oo lagu rakibo.
Si ka duwan dhalooyinka muraayadaha lagu dhejiyo, dhalooyinka birta ah waxay u baahan yihiin feejignaan yar marka la raraynayo, daaha muraayadda ayaa waxyeello u geysan kara inta lagu jiro dhoofinta.Haddii dahaarka dhalada ee haanta uu dhaawacmo ama dillaaco sababtoo ah maaraynta qallafsan inta lagu jiro dhoofinta ama rakibidda, lama ogaan doono ilaa taangiga uu ku guuldareysto xilli hore.
Taangiyada birta ah ayaa guud ahaan awood u leh inay u adkeystaan ​​heerkulka biyaha sare marka loo eego taangiyada muraayadaha, iyo heerkulka ka sarreeya 180F ma soo bandhigi doonaan wax dhibaato ah.Qaar ka mid ah taangiyada muraayadaha muraayadaha ayaa u nugul cadaadiska heerkulka sare, taas oo keeneysa khatar sare oo waxyeello dhalada ah.
Waxaa lagugula talinayaa inaad la tashato soo saaraha taangiga muraayadda leh ee heerkulka ugu sarreeya ee lagu taliyey. Taangiyada birta aan fiicnayn ayaa badanaa ah doorasho ka wanaagsan codsiyada heerkulka sare.
Shaki kuma jiro in qiimaha bilawga ah ee taangiga birta ah uu ka sarreeyo kan taangiga muraayadda ah. Laakiin sababaha halkan lagu sheegay, kharashka wareegga nolosha ee taangiga muraayadda ayaa laga yaabaa inuu sare u kaco.Marka la barbardhigo kharashka wareegga nolosha, taangiyada birta ah ayaa guud ahaan qiimo badan oo waxtar leh mustaqbalka fog waana in la tuso macaamiisha.
