Uphahla Oluntantayo Uma Luqhathaniswa Nokulawulwa Komhwamuko Ngegesi Engasebenzi Nangesembozo
Kwadalwa ngo Ngokwamukisa
Uphahla Oluntantayo Ngokumelene Negesi Engasebenzi Nokulawula Umhwamuko Wokumboza
Uphahla Oluntantayo Ngokumelene Negesi Engasebenzi Nokulawula Umhwamuko Wokumboza kunqunywa umkhiqizo ogciniwe, ububanzi bethangi, umthetho wezinto ezikhishwayo kanye nezindleko zomjikelezo wokuphila - hhayi ukuthanda okujwayelekile. Inketho ngayinye iyawina endaweni echaziwe.
Iyini Inketho Ngayinye
Uphahla oluntantayo kanye negesi engasebenzi / ukumboza kuxazulula izinkinga ezihlangene kodwa ezingafani. Isinyathelo sokuqala ukubiza umsebenzi womsebenzisi: ukulawula umhwamuko, ukuvalwa kwesikhala sengqondo, umkhawulo wezindleko noma ukufinyelela kokunakekela, ngoba impendulo efanele iyashintsha ngomsebenzi.
Imibandela Yesinqumo
· Ukuguquguquka komkhiqizo ogciniwe kanye nephuzu lokushisa.
· Ububanzi bethangi kanye nohlobo lwegobolondo (olugxilile noma oluvulekile phezulu).
· Ikhodi yokukhishwa komoya kanye nomlilo esebenzayo.
· Izindleko zomjikelezo wokuphila uma kuqhathaniswa nezindleko zokuqala.
· Ukufinyelela kokunakekela kanye nesikhathi sokuhlola.
Lapho i-Floating roof Ifaneleka Khona
I-Floating roof iyancanywa lapho inzuzo yayo ethile ihambisana nomsebenzi. Ayikhethwa ngokuzenzakalela; ukushintshana kufanele kubhalwe ukuze umhloli wakamuva abone ukuthi kungani enye indlela yenqatshiwe.
Lapho i-Inert gas / blanketing Ifaneleka Khona
I-Inert gas / blanketing ifaneleka endaweni ehambisanayo. Ukuyisebenzisa ngaphandle kwaleyo ndawo kudala izinkinga zezindleko noma zokuhambisana nezimiso ezifihlwa ukukhetha okujwayelekile.
Indlela Yokukhetha Nokuklama
Indlela ephindwayo igcina ukukhetha kuvikelekile kumathangi afanayo:
1. Bhala umsebenzi womsebenzisi emshweni owodwa ngaphambi kokuqhathanisa uphahla oluntantayo kanye negesi engasebenzi / ukumboza.
2. Bhala uhlu lokuguquguquka, ububanzi kanye nekhodi ebopha ukukhetha.
3. Hlunga uphahla oluntantayo kanye negesi engasebenzi / ukumboza ngokumelene nezindleko zomjikelezo wokuphila, hhayi intengo yokuthenga.
4. Rekhoda inketho enqatshiwe (uphahla oluntantayo noma igesi engasebenzi / ukumboza) kanye nesizathu, ukuze kuhlolwe.
5. Qinisekisa ukukhetha ngokuhambisana nohlelo lokuhlola nokunakekela.
Uhlaka Lokulinganisa (Oluyisibonelo, Hhayi Isibalo Seprojekthi)
Sebenzisa lobu budlelwano ukuhlola Ukuhlolwa Komjikelezo Wokuphila Kophahla Oluntantayo Uma Kuqhathaniswa Negesi Engasebenzi Nokulawula Umhwamuko Wokumboza ngaphambi kokuzibophezela enombolweni:
Izindleko zomjikelezo wokuphila ≈ izindleko zokuqala + (ukulungisa + amandla + isikhathi sokuphazamiseka) phakathi nokuphila kwenkonzo; qhathanisa ngobubanzi obufanayo.
Izindinganiso zokuhlola umjikelezo wokuphila kwe-Floating Roof Versus Inert Gas And Blanket Vapor Control ezingezansi ziyizibonelo futhi zikhona ukukhombisa indlela; azizona izilinganiso zesizinda ezivela kuphrojekthi eqanjiwe futhi kufanele ziqinisekiswe ngaphambi kwanoma yikuphi ukusetshenziswa.

Lapho Lokhu Kuqhathanisa Kusetshenziswa Ngokungalungile
Ukukhetha uphahla oluntantayo uma kuqhathaniswa negesi engasebenzi / ukumboza kusetshenziswa kabi uma kwenziwa ngokwentengo kuphela, uma ukuguquguquka komkhiqizo nobubanzi bethangi kungashiwo kuqala, noma uma inketho enqatshiwe ingabhalwanga. Ngaphandle kwendawo yayo evumelekile, inketho 'elahlekelayo' ephepheni ingaba ukuphela kokukhetha okuhambisana nomthetho empeleni, ngakho umsebenzi - hhayi ukuqhathanisa okuyisihloko - kufanele kunqume.
Ukushintshana Nezingozi
· Uma uphahla oluntantayo lusetshenziswa ngaphandle kwendawo yalo evumelekile, ingozi enkulu ukulahleka komhwamuko kuphahla oluntantayo uma kuqhathaniswa negesi engasebenzi / ukumboza kubangelwa igebe lokuvikela nokulingana kwedekhi; izivikelo eziphindwe kabili nokulingana okuqinile kunciphisa ukukhishwa komoya.
· Uma igesi engasebenzi / ukumboza kusetshenziswa ngaphandle kwendawo yayo evumelekile, ukulawula ukugqwala nokufinyelela kungase kuphazamiseke.
· Noma yikuphi okukhethiwe, isigaba sokufakwa kwezimpawu esingalungile sivumela imililo ye-Rim-seal ukuthi iqale ekukhishweni kukagesi omile, umbani noma umsebenzi oshisayo; isigaba sokufakwa kwezimpawu, ukuhlanganisa kanye nezinhlelo zegwebu kuyalawula ingozi.

· Ukukhetha ngomkhuba esikhundleni somkhiqizo nobubanzi.
· Ukucaphuna izinga ngaphandle kokuhlola ububanzi baso.
· Ukweqa irekhodi lenketho enqatshiwe (kungani kungesilo igesi engasebenzi / i-blanketing).
Ukusekelwa Kobunjiniyela Nezinyathelo Ezilandelayo
Ukuze ucacise I-Floating Roof Versus Inert Gas And Blanket Vapor Control, shono umkhiqizo nokugxilwa kwawo, izinga lokushisa lokusebenza, ingcindezi yomhwamuko kanye nephuzu lokusha, ikhodi yokuklama, ububanzi, ivolumu kanye nokushintshwa. Unjiniyela wabe eseqinisa uhlobo lwophahla lwe-Floating Roof Versus Inert Gas And Blanket Vapor Control, isigaba sokuvaleleka kanye nesisekelo sokuhlola, hhayi isincomo esijwayelekile.
Imibuzo Evame Ukubuzwa
1. I-Floating roof noma i-Inert gas / blanketing - yikuphi okufanele ngikukhethe?
Khetha ngokomkhiqizo ogciniwe, ububanzi bethangi kanye nekhodi esebenzayo. Ithebula lokuqhathanisa lixhumanisa ngakunye nesimo salo; ngaphandle kwaleso simo, enye indlela ayilungile, ayishibhile.
2. Ingabe izindleko ziyayinquma?
Izindleko zokuqala zodwa azikunqumi; izindleko zomjikelezo wempilo, impilo yesigaba sokufakwa kwezimpawu kanye nokufinyelela kokuhlola ngokuvamile kuyabusa ngaphezu kwentengo yokuthenga.
3. Ngingashintsha kamuva?
Ukuguqulwa kungenzeka kwezinye izimo (isibonelo, uphahla olungagxili kuya kuphahla oluntantayo lwangaphakathi) kodwa kudinga ukuhlolwa kabusha kwegobolondo, isigaba sokufakwa kwezimpawu kanye nokukhipha umoya.
4. Yimiphi imigomo esebenzayo?
Ku-Floating Roof Versus Inert Gas And Blanket Vapor Control, isisekelo yi-API 650 ne-EN 14015 nokukhipha umoya kwe-API 2000; i-EPA Benzene NESHAP iyasebenza lapho kukhona i-benzene.
5. Iyiphi iphutha elikhulu kakhulu?
Ukukhetha ngomkhuba noma ngentengo nokushaya indiva ukuguquguquka komkhiqizo nobubanzi obuyisisekelo esidingekayo.
6. Ngiqinisekisa kanjani ukukhetha?
Qinisekisa okokufaka kwe-Floating Roof Versus Inert Gas And Blanket Vapor Control - idatha yomkhiqizo, ububanzi, ukushintshwa kanye nekhodi - bese uthola unjiniyela ukuthi ahlole uhlobo lwedekhi, isigaba se-seal kanye nokubekezelelana.
7. Isinqumo sirekhodwa kuphi?
Encazelweni kanye neBhuloho Yenani Eliyingqayizivele ukuze inketho enqatshiwe kanye nesizathu sayo kuhlolwe.
I-Floating Roof Versus Inert Gas And Blanket Vapor Control kunqunywa umkhiqizo ogciniwe othile, ingcindezi yawo yomhwamuko, izinga lokushisa, indawo yokugqwala kanye nekhodi esebenzayo - hhayi umkhuba. Qala ngezimo zokusebenza, uzihlanganise nohlobo olulungile lwe-floating-roof kanye nekilasi le-seal, bese uqinisekisa ukubekezelelana kwedekhi, i-seal kanye nogqinsi lwe-shell ngokumelene nezinga elikhethiwe. Lapho kudingeka izilinganiso eziqondene nephrojekthi, inani lamathangi noma umthamo, qinisekisa lokho ngokumelene nerekhodi lethangi eliqinisekisiwe ngaphambi kokuqedela isicaciso.
