INDLELA YOKUXELISA INDLELA YOKUGQIBELA I-SCBA CY: Ukuqonda ixesha lokusebenza le-carbon fiber

I-Apting Spritus (SCBA) isilindas zibalulekile ekunikezeleni umoya wokuphefumla ukuya kuthi ga kwi-windows, abasebenzi abahlangulayo, kunye nabanye abasebenzi abasebenza kwiindawo ezinobungozi. Ukwazi ukuba iI-SCBA CylinderIza kuhlala ngexesha lokusetyenziswa kubalulekile ekucwangciseni ukusebenza nasekuqinisekiseni ukhuseleko. Ixesha lokusebenza kwesilinda lixhomekeke kumthamo, uxinzelelo, kunye nenqanaba lokuphefumla lomsebenzisi. Eli nqaku liza kukuhamba ngendlela yokubala ubungakanani beI-SCBA Cylinder, usebenzisa ifomula elula, ethathele ingqaleloI-carbon fiber ye-carbon sylinders, ezisetyenziswa ngokubanzi ngenxa yokukhanya kwazo kunye namandla abo.

I-SCBA CylinderIsiseko: Umthamo kunye noxinzelelo

I-SCBA CylinderGcina umoya oxinzelelweyo kwingcinezelo ephezulu, idla ngokulinganiswa kwimivalo okanye kwiiprints kwi-intshi nganye kwi-intshi (i-PSI). Umthamo womoya ngaphakathi kwi-cylinder ihlala ibonakaliswa kwiilitha. Ezona zinto zimbini ziphambili ezichaza ukuba ingakanani na umoya okhoyo:

• Ivolumu yesilinda: Lo ngubukhulu wangaphakathi wesilinda, obonakala kwiilitha (umz., I-6.8-ilitha okanye i-9-ilitha).
• Uxinzelelo lweCylinderIngcinezelo apho umoya ugcinwe khona, ngokwesiqhelo phakathi kwe-200 ne-300 bar yeI-SCBA Cylinders.

I-carbon fiber ye-carbon sylinderI-s ithandwayo kwiinkqubo ze-SCE ngenxa yokuba zibonelela ngesikhundla soxinzelelo esiphezulu (ukuya kuthi ga kwi-300 bar) ngelixa silula kakhulu kune-teel okanye i-aluminium yentsimbi. Oku kubangela ukuba balungele iimeko apho abasebenzisi kufuneka bahambe ngokukhawuleza okanye ixesha elide.

The fomula yokubala ixesha le-SCA

Ixesha lokusebenza kweI-SCBA CylinderIngabalwa kusetyenziswa le fomula ilandelayo:

• I- "40" kwifomula ibonisa umndilili wokuphefumla womntu ophantsi kweemeko zomsebenzi ophakathi. Eli nqanaba lingahluka ngokuxhomekeka ekubeni umsebenzisi usebenza kangakanani, kodwa iilitha ezingama-40 ngomzuzu (l / min) ngumfanekiso oqhelekileyo.
• I- "--10" ekupheleni kwefomula ngumda wokhuseleko, ukuqinisekisa ukuba umsebenzisi unexesha lokuphuma kwindawo enobungozi ngaphambi kokuba umoya uphume ngokupheleleyo.

Umzekelo ubalo:

Masibale ixesha lokusebenza kwi-6.8-ilithaI-carbon fiber scba cybar, icinezelwe i-300 bar.

Kulo mzekelo,I-SCBA CylinderUngabonelela malunga nemizuzu engama-35 yomoya ophefumlayo ngaphambi kokuba ufuna ukutshintshwa okanye ukugcwaliswa. Oku kubalo kuthatha umsebenzi owongameleyo wokwenza umzimba, kwaye ixesha lokusetyenziswa kwexesha elifanelekileyo lingahluka xa umsebenzisi uzibhokoxa nangaphantsi.

Izinto eziphelelwe lixeshaukuthobaI-SCBA CylinderIxesha

Ngelixa ifomula ibonelela ngoqikelelo olusisiseko, izinto ezininzi zinokuba nefuthe

Ixesha lokwenyani leI-SCBA Cylinderisetyenzisiwe. Ukuqonda ezi zinto zibonakalayo sisitshixo sokuqinisekisa ukusebenza ngokukhuselekileyo.

1. Ixabiso lokuphefumla

Ifomula ithatha impilo ephakathi

I-Hing Inqanaba le-40 l / imiz, elihambelana nomsebenzi ophakathi. Ngokwenyani, inqanaba lokuphefumla linokutshintsha ngokuxhomekeka kumthwalo womsebenzisi:

• Umsebenzi ophantsi: Ukuba umsebenzisi uphumle okanye enze umsebenzi wokukhanya, inqanaba lokuphefumla lingaphantsi, malunga ne-20-30 l / min, elinokwandisa ixesha le-cylinder.
• Umsebenzi ophezulu: Ngexesha lokusebenza komzimba okunzima, njengokulwa imililo okanye ukuhlangula abantu, amazinga okuphefumla anokonyusa ukuya kwi-50-60 l / min okanye ngaphezulu, ukunciphisa ixesha lokuhamba.

2. Uxinzelelo lweCylinder

Ii-cylinds eziphambili ze-cylinds zibonelela ngomoya ongaphezulu.I-carbon fiber cylinderSuqhelene ngokusebenza kwiingcinezelo ezikude ukuya kwi-300 bar, xa kuthelekiswa nentsimbi okanye iisilinda ze-aluminium, ezinokuthi zithintelwe kwi-200 bar. Uxinzelelo oluphezulu luvumelaI-carbon fiber cylinders ukubamba umoya ngakumbi kwiphakheji encinci, elula, yandisa ixesha lokusebenza.

3. Umda wokhuseleko

Umphawu wokhuseleko owakhiwe kwifomula (-10) iqinisekisa ukuba

Umsebenzisi akaphumi emoyeni ngelixa kwindawo eyingozi. Kubalulekile ukuhlonipha le buffer xa kubalwa ixesha lokusebenza kunye nokucwangcisa ukusetyenziswa komoya, ngakumbi kwiimeko apho indlela yokuphuma inokuthatha imizuzu eliqela ukuba ihambile.

Indima yeI-carbon fiber ye-carbon sylinders

I-carbon fiber ye-carbon sylinderSukhe waba lukhetho olukhethiweyo kwiinkqubo ze-SBAs ngenxa yoyilo lwabo olukhanyayo kunye nobuchule bokukhanya. Xa kuthelekiswa nentsimbi kunye ne-aluminium cylinds,I-carbon fiber cylinderS unike izibonelelo ezininzi:

• Ubunzima: I-carbon fiber cylinderI-s ilula kakhulu kunentsimbi, ibengela ukuba ibe lula ukuyiphatha kunye nokunciphisa ukudinwa komsebenzisi ngexesha lokusebenza okwandisiweyo.
• Uxinzelelo oluphezulu: Banokugcwaliswa ngokunyanzela ukuya kwi-300 bar, ukubonelela ngomoya ngakumbi ngaphandle kokunyusa ubungakanani be-cylinder.
• Ukuqina: I-carbon fiber yefibres yomelele kakhulu, iyakwazi ukumelana neengcinezelo eziphezulu ngelixa ikwanyangeka kwimpembelelo kunye nezinto zokusingqongileyo.

Uyilo olukhanyayo lubaluleke ngokukhethekileyo kubasebenzi abahlangulayo abafuna ukuhlala beselfowuni ngelixa bethwala ezinye izixhobo, ezinjengezixhobo zokucima umlilo okanye iigiya zonyango. Ngaphandle kweengenelo,I-carbon fiber cylinders uze nenye yeemfuno ezongeziweyo zolondolozo, njengokuvavanywa rhoqo kwe-hydrostatic ukuqinisekisa ukuba bahlala bekhuselekile phantsi koxinzelelo.

Uvavanyo lwe-hydrostatic kwayeI-SCBA CylinderIsondlo

Ukugcina ukuthembeka kweI-SCBA CylinderS, kubandakanya iimodeli ze-carbon fiber, ulondolozo oluqhelekileyo lubalulekile. Oku kubandakanya:

• Uvavanyo olubonakalayo: Jonga umonakalo, onjenge-rocks okanye iidenti, ngaphambi kokusebenzisa.
• Uvavanyo lwe-hydrostatic: I-carbon fiberI-SCBA CylinderI-s ifuna uvavanyo lwe-hydrostatic qho kwiminyaka emihlanu ukuqinisekisa ukuba banokuphatha uxinzelelo oluphezulu abachaphazelekayo. Olu vavanyo lujonga naluphi na ulwando kwisilinda esinokubonakalisa ukrakra kwezinto.
• Ukutshintshwa: Nokuba ngolondolozo olufanelekileyo,I-carbon fiber scba cybarUnexesha lokuphela kwe-Lifepan, ihlala ijikeleze iminyaka eli-15, emva koko kufuneka itshintshwe.

Ukuqukumbela

Ukwazi indlela yokubala amandla kunye nexesha lokusebenza leI-SCBA Cylinderyi

Kubalulekile ukuba nabani na oxhomekeke kwezi zixhobo kwiindawo ezinobungozi kwiindawo ezinobungozi. Sebenzisa ifomula(Umthamo × yoxinzelelo) / 40 - 10, u-caqikelela ixesha elikhoyo kulo naluphi na u-cylinder onikiweyo, ukugcina engqondweni yokuba iirhafu zokuphefumla, uxinzelelo, kunye nemarike yokhuseleko yonke idlala indima kwixesha lokugqibela.

I-carbon fiber ye-carbon sylinderS, ngoyilo lwabo olukhanyayo kunye nobuchule bokukhanya kunye nobuchule bokufumana uxinzelelo oluphezulu, kukhetho oluthandwayo lweenkqubo ze-SBA iinkqubo. Banika ixesha elide umsebenzi wokusebenza kunye nokuphuculwa kokuhamba ngokuthelekiswa nentsimbi okanye ii-aluminium cylinds. Nangona kunjalo, ukulungiswa rhoqo, kubandakanya uvavanyo olubonakalayo kunye novavanyo lwe-hydrostatic, kubalulekile ukuqinisekisa ukuba ezi zilinda zihlala zikhuselekile kwaye ziyasebenza ebomini babo bonke.

Ukuqonda le miba yeI-SCBA CylinderUmthamo uya kunceda ekuqinisekiseni ukusetyenziswa ngokukhuselekileyo nangokufanelekileyo kwiimeko ezinzima, apho yonke imzuzu yokuphefumla ingenza umahluko.
