ULondolozo lweSilinda ye-SCBA: Nini kwaye Njani ukubuyisela iiSilinda eziSongelweyo zeFayibha eDityanisiweyo

Izixhobo zokuphefumula ezizimeleyo (SCBA) ziyimfuneko kubacimi bomlilo, abasebenzi bokuhlangula, kunye nabanye abasebenza kwiindawo ezinobungozi.SCBA isilindas zibonelela ngobonelelo olubalulekileyo lomoya ophefumlayo kwiindawo apho umoya ojikeleze umhlaba unokuba netyhefu okanye unqongophele i-oxygen. Ukuqinisekisa ukuba izixhobo zisebenza ngokukhuselekileyo nangempumelelo, kubalulekile ukugcina nokutshintshaSCBA isilindas rhoqo. Kweli nqaku, siza kugxininisai-composite fiber-isongelwe isilindas, ngakumbi i-carbon fiber, enobomi benkonzo ye-15 iminyaka. Siza kuphonononga iimfuno zogcino, kubandakanywa uvavanyo lwe-hydrostatic kunye nokuhlolwa okubonakalayo.

Zintoni iiI-Composite Fiber-Esongiweyo ye-SCBA Cylinders?

I-Composite fiber-isongelwe i-SCBA cylinderIzakhelwe ubukhulu becala ngelayini yangaphakathi ekhaphukhaphu eyenziwe ngezinto ezifana ne-aluminiyam okanye iplastiki, esongelwe ngento eyomeleleyo edibeneyo efana ne-carbon fiber, i-fiberglass, okanye i-Kevlar. Ezi zisilinda zikhaphukhaphu kakhulu kunentsimbi yemveli okanye iisilinda ze-aluminium kuphela, zizenza zilungele ukusetyenziswa kwiimeko ezingxamisekileyo apho ukuhamba kubalulekile.Ikhabhoni fibre-isongelwe SCBA cylinders, ngokukodwa, zisetyenziswa kakhulu kuba zibonelela ngeyona ndibaniselwano ingcono yamandla, ubunzima, kunye nokuqina.

Ubomi beI-Carbon Fiber-Egqitywe nge-SCBA Cylinders

Ikhabhoni fibre-isongelwe SCBA cylinders zinobomi obuqhelekileyo beIminyaka eyi-15. Emva kweli xesha, kufuneka zitshintshwe, kungakhathaliseki ukuba imeko okanye ukubonakala kwazo. Isizathu solu bomi busisigxina ngenxa yokugqoka kunye nokukrazula ngokuthe ngcembe kwizinto ezidibeneyo, ezinokuthi zibe buthathaka ngokuhamba kwexesha, nokuba akukho monakalo obonakalayo okhoyo. Ukutyhubela iminyaka, isilinda sichanabeke kuxinzelelo olwahlukeneyo, kubandakanywa ukuguquguquka koxinzelelo, iimeko zokusingqongileyo, kunye neempembelelo ezinokubakho. Ngelixai-composite fiber-isongelwe isilindas zenzelwe ukusingatha le miqathango, ingqibelelo yezinto iyancipha kunye nexesha, nto leyo inokubeka imingcipheko yokhuseleko.

Ukuhlola Okubonwayo

Enye yezona ndlela zisisiseko kunye nokugcinwa rhoqo kweendlelaSCBA isilindas yiukuhlolwa okubonakalayo. Olu hlolo kufuneka lwenziwe ngaphambi nasemva kokusetyenziswa ngalunye ukuze kubonwe naziphi na iimpawu ezibonakalayo zomonakalo, ezifana neentanda, izibonda, ukukrazuka, okanye umhlwa.

Izinto eziphambili ekufuneka uzijonge ngexesha lokuhlolwa okubonakalayo ziquka:

• Umonakalo womphezulu: Khangela naziphi na iintanda okanye iitshiphusi ezibonakalayo kwi-cylinder's composite wrap yangaphandle.
• Izibonda: Izibonda okanye i-deformation kwimilo ye-cylinder ingabonisa umonakalo wangaphakathi.
• Ukonakala: Ngelixai-composite fiber-isongelwe isilindas ziyakwazi ukumelana nomhlwa kunezentsimbi, nawaphina amalungu esinyithi avele (afana nevalve) kufuneka akhangelwe iimpawu zokurusa okanye ukuguga.
• I-Delamination: Oku kwenzeka xa iileya ezidityanisiweyo zangaphandle ziqala ukwahlula kwi-liner yangaphakathi, enokuthi ibeke esichengeni amandla e-cylinder.

Ukuba kukho nayiphi na le miba ifunyenwe, isilinda kufuneka isuswe kwinkonzo ngoko nangoko ukuze iphononongwe ngakumbi.

IiMfuno zoVavanyo lwe-Hydrostatic

Ukongeza kuhlolo olubonakalayo rhoqo,SCBA isilindakufuneka iqhubeuvavanyo lwe-hydrostaticngamaxesha amisiweyo. Uvavanyo lwe-Hydrostatic luqinisekisa ukuba i-cylinder isenokuthi igcine ngokukhuselekileyo umoya woxinzelelo oluphezulu ngaphandle kokubeka umngcipheko wokugqabhuka okanye ukuvuza. Uvavanyo lubandakanya ukuzaliswa kwe-cylinder ngamanzi kunye nokucinezela ngaphaya kwamandla aqhelekileyo okusebenza ukujonga nayiphi na imiqondiso yokwandiswa okanye ukungaphumeleli.

Ubuninzi bovavanyo lwe-hydrostatic luxhomekeke kuhlobo lwesilinda:

• Iisilinda ezifakwe kwi-Fiberglasskufuneka ivavanywe nge-hydrostatic rhoqoiminyaka emithathu.
• Ikhabhon fibre-isongelwe isilindaskufuneka kuvavanywa rhoqoiminyaka emihlanu.

Ngethuba lovavanyo, ukuba i-cylinder yandisa ngaphaya kwemida eyamkelekileyo okanye ibonisa iimpawu zoxinzelelo okanye ukuvuza, iya kuphumelela uvavanyo kwaye kufuneka isuswe kwinkonzo.

Kutheni iminyaka eyi-15?

Usenokuzibuza ukuba kuthenicarbon fiber-isongelwe SCBA cylinders zinobomi obukhethekileyo beminyaka eyi-15, nokuba kukugcinwa rhoqo kunye novavanyo. Impendulo ixhomekeke kubume bezinto eziyintlanganisela. Ngelixa unamandla kakhulu, i-carbon fiber kunye nezinye ii-composites nazo ziphantsi kokudinwa kunye nokuthotywa kwexesha.

Imiba yokusingqongileyo efana nokutshintsha kobushushu, ukuba sesichengeni kukukhanya kwelanga (imitha ye-UV), kunye neempembelelo zoomatshini zinokuwenza buthathaka amaqhina kwiileya ezidibeneyo. Nangona olu tshintsho lungenakubonakala ngokukhawuleza okanye lubonakaliswe ngexesha lovavanyo lwe-hydrostatic, imiphumo eyongezelelweyo ngaphezu kweminyaka eyi-15 yandisa kakhulu umngcipheko wokungaphumeleli, yingakho ii-arhente ezilawulayo, ezifana neSebe lezoThutho (DOT), igunya lokutshintshwa kwi-15- uphawu lonyaka.

Iziphumo zokuNgahoyi uTshintsho kunye noLondolozo

Ukusilela ukubuyisela okanye ukugcinaSCBA isilindas kunokukhokelela kwimiphumo eyintlekele, kuquka:

1. Ukusilela kwesilinda: Ukuba i-cylinder eyonakeleyo okanye ebuthathaka isetyenzisiweyo, kukho umngcipheko wokugqabhuka phantsi koxinzelelo. Oku kunokubangela ukwenzakala kakhulu kumsebenzisi nakwabanye abakufutshane.
2. Ukuhanjiswa komoya okuncitshisiweyo: I-cylinder eyonakeleyo ayinakukwazi ukubamba umthamo womoya ofunekayo, ukunciphisa umoya wokuphefumula okhoyo womsebenzisi ngexesha lokuhlangula okanye umsebenzi wokucima umlilo. Kwiimeko ezisongela ubomi, umzuzu ngamnye womoya ubala.
3. Izohlwayo ezilawulayo: Kumashishini amaninzi, ukuthotyelwa kwemigaqo yokhuseleko kunyanzelekile. Ukusebenzisa iisilinda eziphelelwe lixesha okanye ezingavavanywanga kunokukhokelela kwisohlwayo okanye ezinye izohlwayo ezivela kubalawuli bokhuseleko.

IiNdlela zokuSebenza ezingcono zeI-SCBA CylinderULondolozo kunye noTshintsho

Ukuqinisekisa ukuba iisilinda ze-SCBA zihlala zikhuselekile kwaye zisebenza ubomi babo bonke, kubalulekile ukulandela ezi ndlela zingcono:

1. Ukuhlolwa okubonakalayo rhoqo: Khangela iisilinda ukuba kukho naziphi na iimpawu zomonakalo ngaphambi nangemva kokusetyenziswa ngakunye.
2. Uvavanyo lwe-hydrostatic olucwangcisiweyo: Gcina umkhondo wokuba isilinda ngasinye sagqibela nini ukuvavanywa kwaye uqinisekise ukuba sivavanywa kwakhona kwixesha elimiselweyo (rhoqo kwiminyaka emihlanucarbon fiber-isongelwe isilindas).
3. Ukugcinwa ngokufanelekileyo: IvenkileSCBA isilindakwindawo epholileyo, eyomileyo, kude nelanga elithe ngqo okanye amaqondo obushushu agqithisileyo, anokukhawulezisa ukuwohloka kwezinto.
4. Tshintsha ngexesha: Musa ukusebenzisa iisilinda ezingaphaya kweminyaka eyi-15 yokuphila kwazo. Nokuba babonakala bekwimeko entle, umngcipheko wokungaphumeleli uyanda kakhulu emva kweli xesha.
5. Gcina iirekhodi ezineenkcukacha: Gcina iilog zemihla yokuhlolwa, iziphumo zovavanyo lwe-hydrostatic, kunye neeshedyuli zokutshintshwa kwe-cylinder ukuqinisekisa ukuthotyelwa kwemimiselo kunye nemigaqo yokhuseleko.

Ukuqukumbela

SCBA isilindaIi-s, ngakumbi ezo zisongelwe nge-carbon fibre, zizixhobo eziyimfuneko kwabo basebenza kwindawo ezinobungozi. Ezi silinda zibonelela ngesisombululo esikhaphukhaphu kodwa esomeleleyo sokuthwala umoya oxinanisiweyo. Nangona kunjalo, beza nokugcinwa okungqongqo kunye neemfuno zokutshintshwa ukuze kuqinisekiswe ukhuseleko. Ukuhlolwa okubonakalayo rhoqo, uvavanyo lwe-hydrostatic rhoqo emva kweminyaka emihlanu, kunye nokutshintshwa ngexesha elifanelekileyo emva kweminyaka eyi-15 zizenzo eziphambili ezinceda ukugcinaSCBA isilindas ethembekileyo kwaye ikhuselekile ukuyisebenzisa. Ngokuthobela ezi zikhokelo, abasebenzisi banokuqinisekisa ukuba banomoya abawudingayo xa kubaluleke kakhulu, ngaphandle kokubeka engozini ukhuseleko.
