Iityhubhu kwiTube yokuTshintsha ubushushu: IsiKhokelo esiBanzi Eli nqaku libonelela ngenkcazo eneenkcukacha ityhubhu kwizitshintshi zobushushu betyhubhu, ukuhlola uyilo lwabo, izicelo, iingenelo, izinto ezingeloncedo, kunye neendlela zokukhetha. Siphengulula kwiindidi ezahlukeneyo, izixhobo, kunye nokubala, sinikezela ngemibono esebenzayo yeenjineli kunye neengcali ezisebenza ngeenkqubo zokuhambisa ubushushu.
Iityhubhu kwizitshintshi zobushushu betyhubhu, eyaziwa ngokuba yimibhobho ephindwe kabini yokutshintshiselana kobushushu, iphakathi kwezona ntlobo zilula kwaye zisisiseko zabatshintshi bobushushu. Zisetyenziswa ngokubanzi kumashishini ahlukeneyo ukwenzela ukuhanjiswa kobushushu phakathi kweencindi ezimbini. Esi sikhokelo siya kukunceda uqonde ukusebenza kwabo, ukuqwalaselwa koyilo, kunye nokusetyenziswa okusebenzayo. Siza kuphinda sixoxe ngenkqubo yokukhetha, ngokuqwalasela izinto ezifana namazinga okuhamba, ukuhluka kweqondo lokushisa, kunye nokuhla koxinzelelo. Ukuqonda le miba kubalulekile ekusebenzeni ngokupheleleyo kunye nokuthembeka kwexesha elide.
Ukuqonda iSiseko seThubhu kwi-Tube Heat Exchangers
Uyilo kunye noKwakha
A ityhubhu kwi-tube yokutshintsha ubushushu iqulethe iityhubhu ezimbini, enye ingaphakathi kwenye. Ulwelo luqukuqela kwityhubhu yangaphakathi, ngelixa ulwelo lwesibini luqukuqela kwisithuba sonyaka phakathi kweetyhubhu zangaphakathi nezingaphandle. Ukutshintshwa kobushushu kwenzeka ngodonga lwetyhubhu, luququzelelwa ngokuqhuba kunye nokuhamba. Ulwelo lunokuhamba ngeendlela ezihambelanayo (indlela efanayo) okanye i-counter-current (icala elichaseneyo) amalungiselelo, kunye ne-counter-current flow ngokubanzi ebonelela ngokusebenza okuphezulu.
Iindidi zeMibhobho kwi-Tube Heat Exchangers
Iiyantlukwano zikhona ngokuxhomekeke kwisicelo esithile kunye neemfuno. Ezi ziquka:
- Izitshintshi zobushushu ezinendlela enye: Ulwelo luqukuqela kube kanye kwiityhubhu ezifanelekileyo.
- Izitshintshi zobushushu ezininzi: Ulwelo ludlula amaxesha amaninzi kwiityhubhu, ukwandisa ukusebenza kakuhle kokudluliselwa kobushushu. Oku kunokubandakanya i-U-turn okanye olunye ulungelelwaniso.
- Ngaphandle okanye ngaphandle kweengxaki: I-Baffles inokonyusa isiphithiphithi kunye nokunyusa ukuhanjiswa kobushushu, kodwa inokonyusa uxinzelelo.
Izinto eziphathekayo
Ukukhethwa kwezinto kuxhomekeke kumanzi abandakanyekayo, amaqondo obushushu okusebenza kunye noxinzelelo, kunye neemfuno zokumelana nokubola. Izinto eziqhelekileyo zibandakanya insimbi engenasici, ubhedu, kunye ne-alloys ezahlukeneyo. Ukhetho lufuna ukuqwalaselwa ngenyameko ukuqinisekisa ukuhambelana kunye nokuphila ixesha elide.
Izinto eziluncedo kunye nezingeloncedo zeTube kwiTube yokuTshintsha ubushushu
Iingenelo
Aba batshintshiselwano baziwa ngokuba:
- Ukulula koyilo kunye nokwakhiwa.
- Iindleko eziphantsi.
- Ukucoca ngokulula kunye nokugcinwa.
- Ifanelekile kwizicelo zoxinzelelo oluphezulu.
Iingxaki
Eminye imida ekufuneka iqwalaselwe ibandakanya:
- Indawo yokudlulisa ubushushu ephantsi ngokwenani leyunithi nganye xa kuthelekiswa noyilo oluntsonkothileyo.
- Ukusetyenziswa okulinganiselweyo kumazinga aphezulu kakhulu okudluliselwa kobushushu.
- Ukubakho kokungcola kunye nokukala.
Usetyenziso lwe-Tube kwi-Tube Heat Exchangers
Iityhubhu kwizitshintshi zobushushu betyhubhu zisetyenziswa kumashishini amaninzi, kubandakanywa:
- Ukulungiswa kweekhemikhali
- Ukulungiswa kokutya nesiselo
- Imveliso yamayeza
- Ukuveliswa kwamandla
- Iinkqubo zeHVAC
Usetyenziso oluthile luhlala lubandakanya ukufudumeza okanye ukupholisa ulwelo okanye iigesi, ezinje ngokufudumeza ukutya kwempahla kwisixhobo sokwenza imichiza, ukufakwa kobisi ekulungiseni ukutya, okanye ukupholisa ioyile yokuthambisa koomatshini. Ukulula kwabo kunye nokuqina kwabo kubenza ukuba bakhethe ukhetho olukhethiweyo kwiimeko ezininzi.
UkuKhetha nokuNqatshelwa koYilo
Izinto Emaziqwalaselwe
Ukukhetha okufanelekileyo ityhubhu kwi-tube yokutshintsha ubushushu ifuna uhlalutyo olucokisekileyo lweeparamitha ezininzi:
- Amazinga okuhamba kolwelo
- Umahluko wobushushu
- Uxinzelelo lwehla
- Iimpawu zolwelo (i-viscosity, i-thermal conductivity, njl.)
- Ukuhambelana kwezinto
- Ubushushu obufunekayo
Ukubala kunye nobungakanani
Ubungakanani obufanelekileyo kunye noyilo lufuna ukusetyenziswa kwezibalo zokudluliselwa kobushushu, rhoqo kubandakanya indlela yelog yentsingiselo yomahluko wobushushu (LMTD). Isoftware ekhethekileyo okanye iincwadi zobunjineli zinokunceda ekumiseleni imilinganiselo efanelekileyo kunye noqwalaselo lwesicelo esinikiweyo. Kubalulekile ukubandakanya iinjineli ezinamava kule nkqubo ukuqinisekisa ukusebenza ngokufanelekileyo nangokukhuselekileyo.
ULondolozo kunye nokuCoca
Ukugcinwa rhoqo kubalulekile ukukhusela ukungcola kunye nokulinganisa, okunokunciphisa ukusebenza kakuhle kunye nobomi.
