Ngaphandle kwexabiso eliphezulu, iitanki zesifudumezi samanzi zentsimbi engenastainless zixabisa kakhulu xa kuthelekiswa neendleko zomjikelo wobomi kwaye kufuneka zinikezelwe ngolo hlobo.
Izifudumezi zamanzi zasekhaya ziintsana zangempela zehlabathi lomatshini.Bahlala bevezwa kwiindawo ezinzima kakhulu kwaye umsebenzi wabo onzima awuhoywa kakhulu.Ecaleni lamanzi le-heater, iiminerali, ioksijini, iikhemikhali kunye nentlenga zonke zihlaselwa.Xa kufikwa ekutshiseni, ukushisa okuphezulu, uxinzelelo lwe-thermal, kunye ne-flue gas condensate inokonakalisa zonke izinto.
Xa kufikwa kulondolozo, izifudumezi zamanzi ashushu zasekhaya (DHW) zonke azihoywanga.Abaninimzi abaninzi bazithatha kancinci izifudumezi zabo kwaye baziqaphela kuphela xa zingasebenzi okanye zivuza.Jonga intonga ye-anode?Sula intlenga?Ngaba sikho isicwangciso sokulondoloza?Yilibale, asikhathali.Akumangalisi ukuba uninzi lwezixhobo zeDHW zinobomi obufutshane.
Ngaba obu bomi bufutshane bunokuphuculwa?Ukusebenzisa izifudumezi ze-DHW ezenziwe ngensimbi engenasici yindlela enye yokwandisa ubude bokuphila.Insimbi engenasici yinto eyomeleleyo kunye neyomeleleyo enika ukuchasana okungcono emanzini kunye nokuhlaselwa komlilo, ukunika i-heater ithuba lokubonelela ubomi benkonzo ende.Ukuphela kokwenyani kwinsimbi engenasici yixabiso eliphezulu lezinto eziphathekayo kunye nokuveliswa.Kwixabiso eliphezulu lokukhuphisana kwe-DHW, i-DHW ixabisa kakhulu i-heater.
Intsimbi engatyiwayo ligama eliqhelekileyo lealloyi ezibolileyo kunye nomxholo wechromium ubuncinane we-10.5%.Ezinye izinto ezifana nenickel, molybdenum, titanium kunye nekhabhoni nazo zingongezwa ukunika ukuxhathisa umhlwa, amandla kunye nokwakheka. Kukho indibaniselwano ezininzi ezahlukeneyo zezi ngxubevange zentsimbi zahlukeneyo ezivelisa "iintlobo" ezithile kunye nokuthi "i-steinless steel stainless" ayithethi ngentsimbi engatyiwayo. ibali lonke.
Ukuba umntu uthe "ndinike imibhobho yeplastiki" ubuya kuzisa ntoni? I-PEX, i-CPVC, i-polyethylene? Zonke ezi ziyimibhobho "yeplastiki", kodwa zonke zineepropati ezihluke kakhulu, amandla kunye nezicelo.Kuyafana nakwizinsimbi ezingenasici. Kukho ngaphezu kwe-150 amabakala ensimbi engenasici, zonke zineepropati ezahlukeneyo kunye nokusetyenziswa. 316L, 316Ti kunye ne444.
Umahluko phakathi kwala mabanga kukugxininiswa kwealloyi kuwo.Zonke "300" zebakala zentsimbi ezingenasici ziqulethe malunga ne-18% yechromium kunye ne-nickel ye-10%.Amabakala amabini angama-316 nawo aqulethe i-2% ye-molybdenum, ngelixa i-316Ti ibakala ine-1% ye-titanium eyongezwe kumxube. Amabanga angama-316, ngakumbi ukuxhathisa okuphezulu kwi-pitting kunye ne-crevice corrosion kwiindawo ze-chloride.I-316Ti yebanga le-titanium inika ukubumba okugqwesileyo kunye nokomelela.IBanga lama-444 linayo i-chromium kunye ne-molybdenum, kodwa ayinayo nayiphi na i-nickel.Ukuthetha ngokubanzi, i-nickel engaphezulu, i-molybdenum, kunye ne-titanium engcono kunye nokuqina kwe-corresion, i-corresion engcono kunye nexabiso le-corro. uthi bane-"stainless steel" isifudumezi samanzi, bajonge ngononophelo amabanga njengoko engengawo umgangatho ofanayo
Insimbi engenasici isetyenziswe kuzo zonke iintlobo ezahlukeneyo zokufudumala kwamanzi.Isetyenziswa ngokuqhelekileyo kwii-heaters ze-DHW ezingathanga ngqo kunye ne-condensing water heaters.Izifudumezi zamanzi ezingenasiphelo ziqulethe i-coil yokudlulisa ukushisa yangaphakathi edibeneyo kwibhoyili okanye i-solar collector loop.Zixhaphake kakhulu eYurophu kunaseCanada ngenxa yolawulo lwe-European hydro kunye neenkqubo zokufudumeza kwamanzi elanga.
Ulwakhiwo lwentsimbi estainless lubandakanya inxalenye enkulu yezi marike zaseYurophu ezingathanga ngqo.EKhanada, iitanki zentsimbi esstainless kunye neglasi-efakwe ngeglasi yentsimbi engathanga ngqo ziyafumaneka, amatanki entsimbi ahlala ephethe ixabiso eliphezulu. Kwizifudumezi zamanzi ezingenatanki ezingacondensing, umtshintshi wobushushu udla ngokwenziwa ngobhedu. abatshintshisi.Izifudumezi zamanzi zetanki eziqhutywa ngokuthe ngqo zihlala ziyinkosi yemarike yesifudumezi samanzi saseKhanada.Intsimbi yekhabhoni eneglasi yentsimbi ilawula le segment.Intsimbi engatyiwayo isetyenziswa ngokuqhelekileyo kwitanki engenatanki okanye ethe ngqo efakwe kwizifudumezi zamanzi ezijingisa amanzi.
Ukwandisa ukusebenza kakuhle kwezi zixhobo, irhasi yeflue kufuneka ipholiswe ngaphantsi kwendawo yombethe ukukhulula ubushushu obufihlakeleyo bamafutha.Isiphumo secondensate ngumphunga wamanzi adiyiweyo osuka kwiimveliso zokutsha zegesi, ezinepH ephantsi kakhulu kunye nobumuncu obuphezulu.
Abatshintshi bokushisa okwenziwe ngentsimbi eqhelekileyo okanye ubhedu kunzima ukujamelana nale gesi ye-condensate ixesha elide.Insimbi engenasici yinto efanelekileyo yokukhetha izinto eziphathekayo ngenxa yokumelana nokunyuka kwe-corrosion kunye nokuguquguquka, ukuvumela ukuba yenze imilo enzima yokutshintshiselana kobushushu.Kukho iintlobo ezininzi ze-condensing tankless water heaters ezisebenzisa insimbi engenasici kunye ne-gardeneration ye-stainless steel exchanger kunye ne-gardeneration yokukhuthaza ukutshintshiselana kobushushu obuphezulu. Iireyithingi ze-EF ukuya kuthi ga kwi-0.97.
Izifudumezi zamanzi zetanki ezinobuchwepheshe bokuxinanisa nazo ngoku ziqala ukusetyenziswa rhoqo, ngakumbi ngolunye utshintsho lwekhowudi yokwakha efuna ukusebenza kakuhle kwesifudumezi samanzi. Kukho iintlobo ezimbini zokwakha eziqhelekileyo kule marike.Iitanki ezineglasi ezifakwe kwiglasi zakha ngokuntywiliselwa ngokupheleleyo okutshintshiselana kobushushu besibini.Ngaphandle (kwicala lamanzi) nangaphakathi (icala lomlilo) leekhoyili zokutshintsha ubushushu zifakwe kwiglasi efakwe iglasi ngaphakathi, kwaye inqanda i-glass-lined ngaphakathi kwetanki. iimodeli ezinetanki yensimbi engenasici kunye nokwakhiwa kweekhoyili aziqhelekanga, kodwa kukho ezininzi ezo zakhiwo zentsimbi ezingenasici.
Iindleko zokuqala zetanki eneglasi ziphantsi ngokwenene, kwaye lixesha kuphela eliya kuxela ukuba ukumelana nobushushu kuya kuba njani kwiimeko ezixinzelelekileyo.Ezi zifudumezi zamanzi zetanki ezintsha ze-condensate ziyakwazi ukuphumeza ukusebenza okuphezulu kunezifudumezi zamanzi ezitshisiweyo ezithe ngqo, kunye nokuphumelela kwe-thermal ukusuka kwi-90% ukuya kwi-96%. izifudumezi zingena kwimarike.
Jonga ngononophelo izifudumezi zamanzi zetanki kwaye uya kufumanisa ukuba uninzi lweentlobo zokutshiselwa ngokuthe ngqo, iikhoyili zangaphakathi ezingathanga ngqo, kunye neetanki zokugcina ezithe tye zineglasi-ezineglasi kunye nolwakhiwo lwentsimbi engenasici.
Ngoko ke, ziziphi iingenelo zensimbi engenasici ngaphezu kweglasi efakwe? Uqinisekisa njani abathengi ukuba batyale imali eninzi kwiitanki zentsimbi? Eyona nto iluncedo kakhulu yensimbi engenasici kukumelana kwayo kwendalo kwi-corrosion yamanzi ahlambulukileyo, eyandisa ubomi benkonzo.Ngenxa yokubunjwa kwayo kwe-alloys yentsimbi enganyangekiyo, iitanki zensimbi ezingenasici zinamandla kwaye zihlala ixesha elide kuneetanki zensimbi ezikhuselayo ze-glass-lined oxide. ukuthintela umhlwa ngokwendalo.
Iitanki ezineglasi, kwelinye icala, zithembele kwiglasi-ezifakwe kwiglasi ukunika umqobo phakathi kwe-carbon steel kunye namanzi.Kunikwe ithuba, i-oksijini kunye neekhemikhali ezisemanzini ziya kuhlasela intsimbi kwaye ziyidle ngokukhawuleza.Kuba phantse akunakwenzeka ukusebenzisa nayiphi na i-coating yokukhusela ngokugqibeleleyo (akukho kuphazamiseka kwe-microscopic okanye iziphene ze-pinhole kwi-tank yokukhusela i-tank yokukhusela i-tank ye-tank ekhuselweyo i-tank ye-rod-line ye-sacrid.
Izibonda ze-anode zedini ziya kuguga ngokuhamba kwexesha, kwaye xa inkqubo igqityiwe, i-electrolysis iya kuqala ukutshabalalisa iindawo zetsimbi eziveziweyo ngaphakathi kwetanki.Izinga apho i-anode iyancipha ixhomekeke kumgangatho wamanzi kunye nomthamo wamanzi asetyenzisiweyo.I-anodes yombingelelo ngokuqhelekileyo ihlala iminyaka emithathu ukuya kwemihlanu, kwaye i-anode inokutshintshwa ukuze ithintele umonakalo omkhulu.
Enyanisweni, ukuhlolwa rhoqo kunye nokutshintshwa kwe-anodes kudla ngokungahoywa, kwaye itanki ivuza, ibangela ukuba yonke iyunithi ithathelwe indawo.Ngokungafaniyo neetanki ezifakwe kwiglasi, iitanki zensimbi ezingenasici azidingi "i-anodes yedini" ukukhusela ukubola kwiindawo zabo.Oku kuthetha ukuba akukho mfuneko yokuhlola okanye ukubuyisela indawo ye-anode, ukugcina ixesha lokugcinwa kwamanzi kunye neendleko zokushisa kwamanzi phezu kobomi.
Ngenxa yokonyuka kokuqina kunye nokumelana nomhlwa, uya kuhlala ufumana iitanki zentsimbi engenaziqinisekiso zinewaranti ende, kunye nabavelisi abathile banikezela ngeziqinisekiso zobomi beetanki.
Iitanki zensimbi ezingenasici nazo zinenzuzo yokuba zikhaphukhaphu xa zithelekiswa neitanki ezifakwe kwiglasi, okwenza kube lula ukuthuthwa, ukuphatha kunye nokufaka.Ubukhulu bodonga lwentsimbi engenasici esetyenziswe kwiitanki ngokuqhelekileyo buncinci kakhulu kuneetanki zetsimbi ezifanayo kunye neglasi.
Ngokungafani neengqayi ezifakwe kwiglasi, izimbiza zetsimbi ezingenasici zifuna ingqalelo encinci xa zithunyelwa, kwaye i-glass lining inokonakala ngexesha lokuthumela.Ukuba i-glass glass ye-tank yonakaliswe okanye iqhekezwe ngenxa yokuphathwa kakubi ngexesha lokuthunyelwa okanye ukufakela, akuyi kwaziwa de itanki iphumelele ngaphambi kwexesha.
Iitanki zensimbi ezingenasici ngokuqhelekileyo ziyakwazi ukumelana nokushisa kwamanzi aphezulu kunamatanki afakwe kwiglasi, kwaye amaqondo okushisa angaphezu kwe-180F akayi kunika nayiphi na ingxaki.Amanye amatanki afakwe ngeglasi axhomekeke ekugxininiseni kwiqondo lokushisa eliphezulu, okubangelwa umngcipheko ophezulu womonakalo owenziwe ngeglasi.Iiqondo lokushisa elingaphezulu kwe-160F linokuba yingxaki kwezinye iilayini zeglasi.Izicelo zokushisa zamanzi eziphakamileyo ezifana nezixhobo zokugcina amanzi zorhwebo ziyakwazi ukubona i-solar water heaters.
Kucetyiswa ukuba udibane nomenzi wetanki eneglasi yeqondo lokushisa eliphezulu elicetyiswayo.Iitanki zetsimbi ezingenasici zidla ngokukhetha ukhetho olungcono kwizicelo zokushisa okuphezulu.
Akungabazeki ukuba iindleko zokuqala zetanki zensimbi ezingenasici ziphezulu kunetanki ene-glass-lined.Kodwa ngenxa yezizathu ezikhankanywe apha, iindleko zomjikelo wobomi betanki ene-glass-lined zingaba phezulu.Xa uthelekisa ezi ndleko zomjikelo wobomi, iitanki zensimbi ezingenasici ngokuqhelekileyo zineendleko eziphezulu kwixesha elide kwaye kufuneka ziboniswe kubathengi.
