Amathangi Kaphethiloli Amelana Nomlilo e-UL 2085: Lapho Ukufakwa Ohlwini Okuvikelwe Kudingeka Khona
I-UL 2085 iyi-UL 142 kanye nokusebenza okuvikelwe: ithangi elidlula ukuhlolwa komlilo wamahora amabili, limelana nokungena kwebhalisti futhi lisinde ekushayweni yimoto, ngokwakhiwa okushisayo nokumelana nomlilo phakathi kwezindonga. Kudingeka lapho ikhodi yomlilo noma umhlinzeki womshuwalense efuna ithangi elingaphezulu elivikelwe, futhi akuthathi indawo ye-UL 142 noma imithetho yokufaka ye-NFPA 30 - iyanezela kuyo.
Isingeniso
I-UL 2085 iwuhlu lwezinto ozifunayo lapho ithangi likadizili elijwayelekile elingaphezulu komhlaba linganele ngokwalo - lapho umthetho womlilo, umhlinzeki womshuwalense noma ukuhlolwa kwengozi kwephrojekthi ngokwayo kudinga ithangi elingakwazi ukumelana nokuchayeka emlilweni futhi ligcine okuqukethwe kwalo kungaphumi. Ingumthetho Wamathangi Okugcina Angaphezulu Komhlaba Avikelwe Oketshezi Oluvuthayo Nolushisayo, futhi yakhelwe ngqo phezu kwe-UL 142 kunokuba iyithathe indawo.
Le ndatshana ichaza umehluko wokwakhiwa phakathi kwethangi le-UL 142 nethangi le-UL 2085 ezingeni olidingayo ukuze ubhale isicaciso, lapho uhlu lokumelana nomlilo ludingeka khona ngempela, ukuthi lokho kuvikelwa kuboniswa kanjani ngokuhlolwa, nokuthi lezi zinhlu ezimbili zihlobana kanjani nomthetho womlilo. Inhloso iwukukuvumela ukuthi usho imfuneko ngokunemba okwanele ukuthi umhlinzeki angakwazi ukuyifeza ngethangi elishibhile.
Njenganoma yiliphi izinga lomkhiqizo, i-UL 2085 ihlola ithangi, hhayi indawo. Isivikelo esiyinikezayo singokoqobo futhi siyalinganiseka, kodwa isinqumo sokuyidinga, kanye nendlela ithangi elibekwe futhi elixhunywe ngayo, kusavela kukhodi yomlilo kanye nokuklama kwakho.
Okwengezwa yi-UL 2085 ku-UL 142
I-UL 2085 ithatha izimfuneko zokwakha ze-UL 142 njengesiqalo sayo bese yengeza ukusebenza kwethangi elivikelwe. Ithangi le-UL 2085 kumele lenelise i-UL 142 kuqala - izinto ezifanayo, ukushisela, imithungo kanye nokuhlolwa kwe-hydrostatic - bese libonisa ukuthi lingamelana nezingozi ithangi elijwayelekile elingaphezulu komhlaba elingakhelwanga ukuziphila. Izivikelo ezintathu ezingeziwe ukumelana nomlilo, ukuvikelwa kokushisa koketshezi olugciniwe, kanye nokumelana nokudutshulwa kanye nokushayiswa yimoto.
Incazelo esebenzayo ukuthi ithangi le-UL 2085 kulindeleke ukuthi ligcine ubuqotho balo futhi libambe uphethiloli walo ngenkathi lichayeke emlilweni onzima, futhi limelane nokungena okubangelwa ukushayisana kwangaphandle noma isigameko se-ballistic. Lapho iphrojekthi idinga ukuthi ithangi lihlale lisebenza ngokuchayeka emlilweni - isibonelo ukugcina iphampu yomlilo noma ijeneretha yezimo eziphuthumayo isebenza - uhlu oluvikelwe luyindlela amakhodi nabashicileli bezinhlangano abayaziyo.
Ukwakhiwa okuvikelwe: ukufakwa kwe-insulation nokuvikela
Ukuzivikela kwakhiwe odongeni lwethangi. Ithangi le-UL 2085 linokuvimbela umlilo kanye nokufakwa kwe-thermal insulation ekwakhiweni phakathi komkhumbi wokuqala nokuvikelwa kwangaphandle, ngakho uketshezi olugciniwe luvikelwa ekushiseni komlilo wangaphandle. Igobolondo langaphandle kanye ne-insulation ndawonye bakha isigaba esivikelwe esihlolwa ukuhlolwa komlilo.
Ukuvikela yisici sesibili. Ithangi lakhiwe futhi lahlolwa ukumelana nokushayiswa yimoto nokungena kwe-ballistic, ngakho ukushayisana noma i-projectile akulivuli umkhumbi wokuqala. Ngokwemibandela yokucaciswa lokhu akusona isembozo osengeza kamuva; kuyingxenye yendlela ithangi elisohlwini elakhiwe ngayo, futhi uhlu luhlanganisa ukuhlanganiswa njengoba kwakhiwe, hhayi ukuthuthukiswa okusetshenziswa endaweni ku-UL 142 unit.
Lapho uhlu olumelana nomlilo ludingeka khona
Ukufakwa kuhlu okumelana nomlilo kuyadingeka lapho ikhodi eyamukelwe noma isiphathimandla esinegunya lokwahlulela sidinga ithangi elingaphezulu komhlaba elivikelwe. I-NFPA 30 kanye nekhodi yomlilo zinikeza izindlela ezivumela ithangi elivikelwe ukuba libekwe ngokwehlukana okuhlukile noma ukuphathwa kwezindawo ezivalelwe ngendlela ehlukile kunethangi elijwayelekile elingaphezulu komhlaba, futhi yimibhalo enquma ukuthi ukuvikelwa okwengeziwe kuyimpoqo yini ekufakweni kwakho.
Imfuneko iphinde ivele ngomhlinzeki womshuwalense kanye nokubuyekezwa kwengcuphe yephrojekthi. Isikhungo sedatha noma isikhungo esibucayi kungase kuqondiswe kuso ukuba sisebenzise ithangi elivikelwe ukuze isitoreji sikaphethiloli sikhululeke emlilweni isikhathi eside ngokwanele ukuze sisekele amaphampu omlilo kanye nokukhiqizwa kukagesi ophuthumayo. Isizathu asikaze sibe ngu-"ithangi libonakala lisengozini" - kuyisimiso esithile sekhodi noma somshuwalense esibiza ithangi elivikelwe, futhi isicaciso kufanele sisho lokho.
Izimpawu zokuhlola nokufakwa kuhlu
I-UL 2085 ikhombisa ukuvikelwa ngokuhlolwa kunokuba kube ngokugomela. Ukuhlolwa komlilo kubeka ithangi esimweni esinzima somlilo wamachibi isikhathi eside ukuze ukwakhiwa kukwazi ukukhombisa ukuthi kuvikela okuqukethwe; ukuhlolwa kwe-ballistic kubeka ithangi ekushayweni kwe-projectile; futhi ukuhlolwa komthelela wemoto kuqinisekisa ukuthi ithangi limelana nokushayisana ngaphandle kokuqhekeka komkhumbi oyinhloko.
Uphawu lokufakwa ohlwini ethangini le-UL 2085 likhomba ukuthi iyithangi elivikelwe elingaphezu komhlaba ngaphansi kwalelo zinga, futhi lihlukile kuphawu lwe-UL 142. Ngenxa yokuthi ukuvikelwa kusungulwa ngokuhlolwa kwesakhiwo esifakwe ohlwini, ipuleti legama kanye nerekhodi lokufakwa ohlwini kuwubufakazi umhloli abusebenzisayo - incazelo yomhlinzeki yethangi "elinezinga lomlilo" ngaphandle kophawu lwe-UL 2085 ayiyona into efanayo.
Ubudlelwano nekhodi yomlilo
I-UL 2085 kanye nekhodi yomlilo kuyahambisana, akukona ukushintshana. Ukufakwa ohlwini kufakazela ukuthi ithangi lingenza njengethangi elivikelwe; ikhodi yomlilo inquma ukuthi ithangi elivikelwe liyadingeka yini nokuthi lingabekwa kanjani. I-NFPA 30 ibhekisela kumathangi angaphezulu avikelwe emibhalweni elawula ukuhlukaniswa, ukuvalelwa kanye nezimo okungabekwa ngazo ithangi eduze kwezinto eziveziwe kunethangi elingenalutho elingaphezulu.
Iphutha ukufunda uhlu njengemvume. Ithangi le-UL 2085 kusadingeka likhishwe umoya, lihlukaniswe futhi lihlukaniswe ngogesi ngaphansi kwe-NFPA 30, futhi kusadingeka lihlangabezane nemithetho yezemvelo esebenza ekugcinweni kukadizili. Uhlu oluvikelwe lushintsha ukuqina kwethangi futhi, ngokusebenzisa ikhodi, izinketho zalo zokubekwa - aluyekisi izidingo zokufakwa.
Umthelela kubukhulu bendawo, isisindo nokufinyelela
Ukungeza ukuzivikela komlilo nokufakwa kwe-thermal insulation kanye negobolondo langaphandle elimelana nokushayiswa kwenza ithangi libe nzima futhi ngokuvamile libe likhulu ngobukhulu bendawo kuneyunithi ye-UL 142 efanayo. Isisekelo nanoma yiluphi uhlelo lokuphakamisa kufanele kubhekele isisindo esengeziwe, futhi isiza kufanele sinikeze indlela nendawo yokubeka ithangi elingadingi lutho uma lingenalutho.
Ukufinyelela kubalulekile ngesikhathi sokulethwa kanye nesevisi. I-envelope evikelwe ingenza kube nzima ukuguqulwa kwensimu - ukusika noma ukushisela igobolondo langaphandle kungabeka engcupheni ukufakwa ohlwini - ngakho ukuxhumana nama-nozzle kufanele kulungiswe kumklamo osohlwini esikhundleni sokwengezwa endaweni. Hlela indawo, i-crane noma i-rigging, kanye nokufinyelela kokuhlola ngaphambi kokuba i-tank i-odwe, hhayi ngemva kokuba isilayishwe elolini.
Ukubhala imfuneko kusipesifikheshini
Bhala imfuneko evikelwe ngokusobala. Shono i-UL 2085 ngenombolo kusipesifikheshini, futhi usho ukuthi i-tank kufanele ifakwe ohlwini njenge-tank evikelwe engaphezulu komhlaba - hhayi nje ukuthi yakhiwe ngokwe-UL 142 ngokufakwa kwe-insulation eyengeziwe. Lapho ikhodi yomlilo noma umhlinzeki womshuwalense eqhuba imfuneko, cabanga leso sibopho ukuze isibopho silandeleke.
Bese kudingeka ubufakazi okushiwo uhlu lukufuna: uphawu lwe-UL 2085 nepuleti legama kuyunithi elethiwe, isiqinisekiso sokuthi umkhiqizi unesevisi efanele yokulandelela, kanye nesisekelo sokuhlola uhlu oluncike kuso. Incazelo ethi "ithangi elimelana nomlilo" ngaphandle kwenombolo yezinga ivula ithuba lokuthi kube neyunithi ehlangabezana negama hhayi ukuhlolwa. Chaza ngokucacile ukusebenza okukhuselwe okuthengayo.
Amaphutha avamile encazelweni
Iphutha elivame kakhulu ukubiza ithangi le-UL 142 ngokuthi "lilinganiselwe umlilo" futhi ukulithatha njengelingana ne-UL 2085. Lezi zinhlu ezimbili zihlukile, futhi yi-UL 2085 kuphela ephethe izivikelo zomlilo, zokushisa nezokudubula. Iphutha lesibili ukucabanga ukuthi i-UL 2085 ithatha indawo ye-UL 142 noma ikhodi yomlilo, kuyilapho empeleni inezela kukho kokubili.
Amaphutha asele ayasebenza. Ukucacisa ithangi elivikelwe ngaphandle kokubala isisindo salo, indawo esihamba kuyo nokufinyelela kuholela kuyunithi engeke ikwazi ukubekwa noma inakekelwe njengoba kudwetshiwe. Futhi ukudida ukumelana nomlilo nokucisha umlilo - ithangi elisinda emlilweni ngokuqhathanisa nesistimu eyicishayo - kushiya umklamo wokuvikela ungaxhunyiwe kuhlelo oluphelele lomlilo. Qamba uhlu, linganisa indawo, futhi gcina imibuzo emibili ihlukene.
