Isikhokelo esiSebenzayo seCarbon Fiber Composite yokuphefumla iiCylinders zoMoya

Izixhobo zokuziphefumlela ezizimeleyo (SCBA) ziyimfuneko kubacimi bomlilo, abasebenzi bokuhlangula, kunye namaqela okhuseleko lwamashishini. Kwintliziyo ye-SCBA luxinzelelo oluphezuluisilindaegcina umoya ophefumlayo. Kule minyaka yangoku,carbon fiber composite cylinders ibe lukhetho oluqhelekileyo ngenxa yolungelelwaniso lwamandla, ukhuseleko, kunye nobunzima obuncitshisiweyo. Eli nqaku libonelela ngohlalutyo olusebenzayo lwecarbon fiber cylinders, ukwaphula ubume bazo, ukusebenza, kunye nokusebenziseka kwimiba eyahlukeneyo.

1. Isakhono kunye noxinzelelo lokuSebenza

Ikhabhon fibre composite cylinders for SCBA ziyilwe ngokwesiqhelo ukujikeleza umthamo osemgangathweni weelitha eziyi-6.8. Lo bungakanani bamkelwe ngokubanzi kuba bunikezela ngolungelelwaniso olusebenzayo phakathi kwexesha lokunikezelwa komoya kunye nokulula ukuphatha. Uxinzelelo olusebenzayo luyi-300 bar, evumela umoya owaneleyo ogcinwe malunga ne-30 ukuya kwi-45 imizuzu yexesha lokuphefumla, kuxhomekeke kumthwalo womsebenzi kunye nesantya sokuphefumla.

Ukukwazi ukugcina umoya ocinezelweyo ngokukhuselekileyo kolu xinzelelo oluphezulu sesinye sezizathu eziphambili zokusebenzisa i-carbon fiber composites endaweni yentsimbi yendabuko. Ngelixa zombini izixhobo zinokumelana noxinzelelo olunjalo, imidibaniso ifezekisa oku ngobunzima obuncinci kakhulu.

2. Izinto zoKwakha kunye noYilo

Ulwakhiwo oluphambili kweziisilindas isebenzisa:

• I-Liner yangaphakathi: Ngokuqhelekileyo i-polyethylene terephthalate (PET), ebonelela ngokungena komoya kwaye isebenze njengesiseko sokugubungela kwangaphandle.

• Ukusonga kwangaphandle: Iingqimba zeCarbon fiber, ngamanye amaxesha zidibene ne-epoxy resin, ukunika amandla kunye nokusabalalisa uxinzelelo.

• Imikhono ekhuselayo: Kwiindlela ezininzi zokuyila, imikhono ye-fire-retardant okanye ii-polymer coatings zongezwa ukuchasana nokugqoka kwangaphandle kunye nokushisa.

Olu yilo lomaleko luqinisekisa ukubaisilindainokubamba uxinzelelo ngokukhuselekileyo ngelixa ihlala ilula kwaye imelana nomonakalo. Xa kuthelekiswa nentsimbi yemveli okanye iisilinda ze-aluminium, ezinobunzima kwaye zilungele ukubola, izinto ezidibeneyo zinika ukuqina okungcono kunye nokuphatha.

3. Ubunzima kunye ne-Ergonomics

Ubunzima buyinto ebalulekileyo ekusebenziseni i-SCBA. Abacimi-mlilo okanye abahlanguli bahlala bephethe izixhobo ezipheleleyo ixesha elide kwiindawo ezinobungozi. Isilinda esiqhelekileyo sentsimbi sinokulingana neekhilogram ezili-12-15, ngelixa acarbon fiber composite cylinderyomthamo ofanayo unokunciphisa oko ngeekhilogram ezininzi.

Isiqheloisilinda esiyintlanganiselas inobunzima obujikeleze i-3.5-4.0 yeekhilogram zebhotile engenanto, kwaye malunga ne-4.5-5.0 yeekhilogram xa ifakelwe imikhono ekhuselayo kunye neendibano zevalvu. Oku kuncitshiswa komthwalo kwenza umehluko obonakalayo ngexesha lokusebenza, kunceda ukunciphisa ukukhathala nokuphucula ukuhamba.

4. Ukuqina kunye noBomi boBomi

Ikhabhon fibre composite cylinders bavavanywa kwimigangatho engqongqo efana ne-EN12245 kunye nezatifikethi ze-CE. Zenzelwe ubomi benkonzo ende, kaninzi ukuya kuthi ga kwiminyaka eyi-15 kuxhomekeke kwisakhelo solawulo.

Enye inzuzo ephambili yolwakhiwo oludityanisiweyo kukuxhathisa umhlwa. Ngelixa iisilinda zentsimbi zifuna ukujonga rhoqo umhlwa okanye ukunxiba komphezulu,carbon fiber cylinderabasengozini kakhulu kwiziphumo zokusingqongileyo. Inkxalabo ephambili iba ngumonakalo ongaphezulu kwindawo yokukhusela, yingakho ukuhlolwa okubonakalayo rhoqo kuyimfuneko. Abanye abavelisi bongeza imikhono echasayo okanye ekwazi ukumelana nedangatye ukomeleza ukhuseleko.

5. Iimpawu zoKhuseleko

Ukhuseleko luhlala luhamba phambili.Ikhabhoni fiber cylinders ziyilwe ngamaleko amaninzi ukulawula uxinzelelo kunye nokuthintela ukusilela ngequbuliso. Bafumana iimvavanyo ezigqabhukileyo apho isilinda kufuneka imelane noxinzelelo oluphezulu kakhulu kunoxinzelelo lokusebenza, rhoqo malunga ne-450-500 bar.

Olunye uphawu lokhuseleko olwakhelwe ngaphakathi yinkqubo yevalvu. Iisilindas ngokuqhelekileyo sebenzisa i-M18x1.5 okanye imisonto ehambelanayo, eyilelwe ukudibanisa neeseti ze-SCBA ngokukhuselekileyo. Ukongezelela, izixhobo zokunciphisa uxinzelelo zinokuthintela ukuxinzezeleka ngokugqithiseleyo ngexesha lokuzaliswa.

6. Ukusebenziseka kwiNdawo

Ukusuka kwimbono ebonakalayo, ukuphathwa kunye nokusetyenziswa kwecarbon fiber composite cylinders ukubenza bafaneleke ngokukodwa umlilo kunye nokuhlangula. Ubunzima obuncitshisiweyo, obudityaniswe noyilo lwe-ergonomic, luvumela ukunika ngokukhawuleza kunye nokulungelelana okungcono kumqolo womsebenzisi.

Imikhono ekhuselayo ikwanceda ekunciphiseni ukuguga ekutsaleni okanye ekudibaneni neendawo ezirhabaxa. Kusetyenziso lwehlabathi lokwenyani, oku kuthetha ukuncipha kwexesha lolondolozo kunye nokutshintshwa kweesilinda ezimbalwa. Kubacimi-mlilo abahamba phakathi kwenkunkuma, izithuba ezimxinwa, okanye ubushushu obugqithisileyo, olu phuculo lokusebenziseka luguqulela ngokuthe ngqo ekusebenzeni okusebenzayo.

7. Ukuhlolwa kunye noLondolozo

Isilinda esihlanganisiweyos zifuna inkqubo yokuhlola eyahlukileyo kuneesilinda zentsimbi. Endaweni yokugxila kwi-corrosion, ingqalelo ibekwe ekuboneni umonakalo wefayibha, i-delamination, okanye i-resin cracking. Uhlolo olubonakalayo ludla ngokuqhutywa kulo lonke ugcwaliso ngokutsha, ngovavanyo lwe-hydrostatic olufunekayo ngamaxesha achaziweyo (ngokuqhelekileyo rhoqo emva kweminyaka emihlanu).

Omnye umda omele uqwalaselwe kukuba nje ukuba ukunyaniseka kwesakhiwo sokusonga i-composite kuphazamisekile, ukulungiswa akunakwenzeka, kwaye isilinda kufuneka sithathwe umhlalaphantsi. Oku kwenza ukuphatha ngononophelo kubalulekile, nangona iisilinda zihlala ziqinile.

8. Izinto eziluncedo ngokujonga nje krwaqu

Ukushwankathela uhlalutyo, iinzuzo eziphambili zecarbon fiber composite cylinders ziquka:

• Ikhaphukhaphu: Kulula ukuthwala, ukunciphisa ukudinwa komsebenzisi.

• Amandla aphezulu: Inokugcina ngokukhuselekileyo umoya kwi-300 bar yoxinzelelo lokusebenza.

• Ukunyangwa koMhlwa: Ubomi obude benkonzo xa kuthelekiswa nentsimbi.

• Ukuthotyelwa kweSiqinisekiso: Idibana ne-EN kunye nemigangatho yokhuseleko ye-CE.

• Ukuphatha Okusebenzayo: I-ergonomics engcono kunye nokuthuthuzela komsebenzisi.

Ezi ngenelo zichaza ukuba kuthenicarbon fiber composite cylinderNgoku lukhetho oluphambili lwezicelo zobungcali zeSCBA kwihlabathi jikelele.

9. Iingqwalasela kunye neMida

Nangona amandla abo,carbon fiber cylinders azinayo imingeni:

• Iindleko: Kubiza kakhulu ukuvelisa kunezinye iindlela zentsimbi.

• Uvakalelo loMphezulu: Iimpembelelo zangaphandle zingabangela umonakalo kwimicu, efuna ukutshintshwa.

• IiMfuno zokuHlola: Iitshekhi ezikhethekileyo ziyimfuneko ukuqinisekisa ukhuseleko.

Kubathengi kunye nabasebenzisi, ukulungelelanisa ezi ngqwalasela kunye neenzuzo zokusebenza ngundoqo. Kwiindawo ezinobungozi obuphezulu, ezifunwa kakhulu, iinzuzo zihlala zigqithisa iintsilelo.

Ukuqukumbela

Ikhabhon fiber composite isilinda umoya ukuphefumlababeke umgangatho weenkqubo zeSCBA zanamhlanje. Ukwakhiwa kwabo okulula, ukusebenza okuqinileyo phantsi koxinzelelo oluphezulu, kunye neempawu zokuphatha eziphuculweyo zibonelela ngeenzuzo ezicacileyo ngaphezu koyilo lwensimbi yendabuko. Ngelixa zifuna ukuhlolwa ngononophelo kwaye ziza ngeendleko eziphezulu, igalelo labo kukhuseleko, ukuhamba, kunye nonyamezelo kwimisebenzi yokusindisa ubomi ibenza babe lukhetho olusebenzayo noluthembekileyo.

Njengoko itekhnoloji ihambela phambili, uphuculo kumandla efayibha, iingubo ezikhuselayo, kunye nokusebenza kakuhle kweendleko kuya kwenza ezi silinda zisasazeke ngakumbi. Okwangoku, bahlala beyingxenye ebalulekileyo ekuqinisekiseni ukusebenza kunye nokhuseleko lwabaphenduli bangaphambili.
