Ukuthembeka kwexesha elide: Ukugcina iGear yokuphefumla yoMlilo ngokuJolisa kwiiCylinders zeCarbon Fiber

Izixhobo zokuphefumla zokucima umlilo zidlala indima ebalulekileyo ekukhuseleni abaphenduli bokuqala kwiindawo ezizaliswe ngumsi, iigesi ezinetyhefu, kunye nomoya ongenawo i-oxygen. I-Self-Contained Breathing Apparatus (SCBA) yinto eqhelekileyo yeemeko ezinjalo. Ukuqinisekisa ukuthembeka kwexesha elide kwezixhobo ze-SCBA akukona nje kuphela imfuneko yokhuseleko kodwa kunye nemfuneko ebonakalayo kwimisebenzi yemihla ngemihla yokucima umlilo. Eli nqaku lichaza indlela yokugcina ngokufanelekileyo izixhobo zokuphefumla zokucima umlilo, ngakumbi kugxininise kukhathalelo kunye nokugcinwa kwecarbon fiber composite cylinders, eziye zaxhaphaka kakhulu kwiiyunithi zangoku zeSCBA.

1. Ukuqonda Amacandelo

Phambi kokuxoxa ngolondolozo, kubalulekile ukuqonda amacandelo aphambili ezixhobo ze-SCBA:

• ubuso (imaski): Ibonelela ngobume obuvaliweyo obujikeleze ubuso bomcimi-mlilo.
• Isilawuli kunye nesivalo semfuno: Ilawula ukuhamba komoya ophefumlayo.
• Ukubopha kunye ne-backplate: Ubamba ngokukhuselekileyo izixhobo kumzimba womcimi-mlilo.
• Isilinda somoya esinekhabhon fiber composite: Ukugcina umoya ophefumulayo ocinezelweyo, ngokuqhelekileyo kwi-bar ye-300 (malunga ne-4,350 psi).
• Igeyiji yoxinzelelo kunye neealam: Nceda esweni umoya oseleyo.

Nganye kwezi nxalenye kufuneka isebenze ngokuchanekileyo, kodwa isilinda sifuna ingqalelo ekhethekileyo ngenxa yoxinzelelo oluphezulu olubandakanyekayo kunye nendima yayo ebalulekileyo ekuqinisekiseni umoya ongaphazamisekiyo.ubonelelo.

2. KutheniI-Carbon Fiber Cylinders?

Ikhabhon fibre composite cylinders zisetyenziswa ngokubanzi kwiiyunithi ze-SCBA namhlanje ngezizathu ezininzi:

• Ikhaphukhaphu: Zilula kakhulu kuneesilinda zentsimbi zendabuko, zinciphisa ukukhathala.
• Umlinganiselo ophezulu wamandla ukuya kubunzima: Ziqulethe ngokukhuselekileyo umoya woxinzelelo oluphezulu ngaphandle kokongeza isambuku esingeyomfuneko.
• Ukuxhathisa umhlwa: Izinto ezisetyenzisiweyo ezisetyenzisiweyo azikho phantsi kwe-corrosion xa kuthelekiswa nentsimbi, ezenza zibe zilungele iindawo ezimanzi okanye ezimanzi.

Nangona ezi zibonelelo zicacile,carbon fiber cylinderKananjalo kufuneka inkathalo ethile ukugcina ukusebenza kunye nokhuseleko ekuhambeni kwexesha.

3. Ukusetyenziswa kwemihla ngemihla kunye neetshekhi ezibonakalayo

Ngalo lonke ixesha umcimi-mlilo egqiba ukusebenzisa i-SCBA, uhlolo olusisiseko kufuneka lulandele:

• Jonga umonakalo: Jonga imikrwelo enzulu, imingxuma, okanye imikrwelo kumphezulu wesilinda. I-scuffs encinci yomphezulu inokwamkeleka, kodwa nantoni na enzulu inokuthi ibeke esichengeni isidima solwakhiwo.
• Hlola ukudityaniswa kwevalvu: Qinisekisa ukuba ivalve ijika kakuhle kwaye ayinabutyobo.
• Jonga uxinzelelo: Iisilinda kufuneka zizaliswe kwakhona ukuba uxinzelelo lwehla ngaphantsi kwamanqanaba okusebenza akhuselekileyo, ngokuqhelekileyo i-90% yomthamo opheleleyo.

Ingqalelo yemihla ngemihla ithintela imiba emincinci ekubeni ibe yingozi enkulu.

4. ULondolozo olucwangcisiweyo kunye noVavanyo

Ukongeza kwiitshekhi zemihla ngemihla, ukugcinwa kwamaxesha ngamaxesha kuyimfuneko. Ishedyuli jikelele ibandakanya:

• Uvavanyo lwe-Hydrostatic: Ifuneka rhoqo emva kweminyaka emi-5 (okanye ngokwemimiselo yendawo). Olu vavanyo loxinzelelo luqinisekisa ukuba isilinda sisenako ukubamba ngokukhuselekileyo uxinzelelo lwayo olulinganisiweyo.
• Ukuhlolwa okupheleleyo okubonakalayo: Idla ngokwenziwa ngonyaka ligcisa eliqeqeshiweyo. Oku kubandakanya ukujonga i-delamination, iifibers eziveziweyo, kunye neempawu zoxinzelelo olugqithisileyo.
• Inkonzo yevalvu: Imisonto kunye netywina kufuneka zihlolwe kwaye zithanjiswe njengoko kufuneka ukuthintela ukuvuza.

Lonke uhlolo nogcino kufuneka lurekhodwe ukuze kulandelelwe umkhondo kunye nokuthotyelwa.

5. Iimeko zokuGcina

Indlela kunye nalapho igiya igcinwa khona ichaphazela kakhulu ubomi bayo:

• Kuphephe ukukhanya kwelanga: Imitha ye-UV inokuthoba umaleko wangaphandle weesilinda ezidibeneyo ngokuhamba kwexesha.
• Ulawulo lobushushu: Ubushushu obugqithisileyo, ngakumbi ubushushu, bunokwenza buthathaka intlaka egcina imicu yekhabhoni kwindawo yayo.
• Gcina womile kwaye ucocekile: Ubumanzi kunye nokungcola kunokufaka isandla kwi-corrosion kwiindawo ze-valve kunye nokonakalisa i-composite layers ukuba ayicocwanga rhoqo.

Sebenzisa izinto zokuxhoma eludongeni okanye iikhompatimenti ezinikezelweyo ukugcina izixhobo zeSCBA zime nkqo nangaphandle emgangathweni.

6. IiNdlela eziKhuselekileyo zokugcwalisa ngokutsha

Ikhabhoni fiber cylinders kufuneka zihlale zizaliswe ngabasebenzi abaqeqeshiweyo besebenzisa izixhobo eziqinisekisiweyo:

• Sebenzisa umoya ococekileyo, owomileyo wokuphefumla: Ungcoliseko lungonakalisa zombini i-cylinder yangaphakathi kwaye lwenzakalise umsebenzisi.
• Kuphephe ukuzalisa ngokugqithisileyo: Soloko ugcwalise kuxinzelelo oluchaziweyo kumenzi, ngokuqhelekileyo 300 bar. Uxinzelelo olugqithisileyo lunokukhokelela ekungaphumelelini okuyingozi.
• Vumela ukupholisa: Umoya uyafudumala ngexesha loxinzelelo. Lindela ukuba iphole phambi kokuba ujonge uxinzelelo lokugqibela.

7. Ubomi beSilinda kunye noMhlalaphantsi

Uninzicarbon fiber cylinders zinobomi benkonzo yeminyaka eyi-15, kuxhomekeke kusetyenziso kunye nemeko. Emva kweli xesha, kufuneka zikhutshwe emsebenzini kwaye zilahlwe ngokufanelekileyo okanye zihlaziywe. Nokuba umphandle ubonakala ulungile, uxinzelelo lwangaphakathi ekuhambeni kwexesha lunokuphazamisa ukhuseleko.

8. Uqeqesho kunye noKwazisa

Bonke abasebenzi bokucima umlilo kufuneka baqeqeshwe kukhathalelo olusisiseko lwezixhobo ze-SCBA, ngakumbi kwindlela yokuchonga iimpawu ezilumkisayo zokunxitywa kwe-cylinder okanye umonakalo. Uqeqesho lwarhoqo luqinisekisa ukuba wonke umntu unokufaka isandla ekubhaqweni kwangaphambili kwemiba kunye nokuphathwa ngokukhuselekileyo kwamacandelo anoxinzelelo oluphezulu.

Ukuqukumbela

Ukugcina izixhobo zokuphefumla zokucima umlilo kuluxanduva ekwabelwana ngalo. Ngelixa onke amacandelo eeyunithi ze-SCBA zifanelwe ingqalelo,carbon fiber composite cylinders zifuna ukuphathwa okukhethekileyo ngenxa yezixhobo zabo, umsebenzi, kunye namanqanaba oxinzelelo. Ngokuhlolwa kwemihla ngemihla, ukugcinwa okufanelekileyo, ukusetyenzwa rhoqo, kunye nokuqonda imida yabo yokusebenza, ezi zisilinda zinokubonelela ngenkxaso ethembekileyo, elula kubacimi bomlilo iminyaka emininzi. Ukubeka phambili ezi ndlela zokulondoloza akuqinisekisi ubomi besixhobo obude kuphela kodwa okona kubalulekileyo, ukhuseleko lwabo baxhomekeke kuzo kwiindawo ezinomngcipheko omkhulu.
