Ukubala indawo yokuhambisa umoya ye-carbon fiber

Intshayelelo

I-carbon fiber cylinderIi-S zisetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanya ukucima umlilo, i-SCBA (i-SCBA enesixhobo sokuphefumla), ukuntywila kunye nokusebenza kwemizi-mveliso. Inqaku elinye lesitshixo kubasebenzisi liyayazi ukuba ixesha elide kangakananiisilindainokuhambisa umoya. Eli nqaku licacisa indlela yokubala indawo yokuhambisa umoya esekwe kwiisilindaIvolumu yamanzi, uxinzelelo lokusebenza, kunye nenqanaba lokuphefumla lomsebenzisi.

UkuqondaI-carbon fiber cylinders

I-carbon fiber ye-carbon sylinderS iquka i-Liner engaphakathi, idla ngokwenziwa nge-aluminium okanye iplasitiki, isongelwe kwimigca ye-carbon fiber yamandla ongezelelweyo. Ziyilelwe ukubamba umoya oxinzelelweyo kwiingcinezelo eziphezulu ngelixa zisala tenneight kwaye ziqinile. Ezona ngcaciso zimbini ziphambili eziphembelela ubude bomoya zezi:

• Ivolumu yamanzi (iilitha): Oku kubhekisele kubume bangaphakathi beisilindaXa izele lulwelo, nangona isetyenziselwa ukumisela ukugcinwa komoya.
• Uxinzelelo lokusebenza (ibha okanye i-PSI): Ingcinezelo aphoisilindaizaliswe ngumoya, ngokwesiqhelo yibar eyi-300 (4350 psi) kwizicelo eziphezulu zoxinzelelo.

Ukubalwa kwenyathelo ngenyathelo lokuhambisa umoya

Ukufumanisa ukuba lide kangakanani i-ACI-Arbon Fylinderinokubonelela ngomoya, Landela la manyathelo:

Inyathelo loku-1: Chonga ivolumu yomoya kwiIsilinda

Kuba umoya unyanzelekile, ivolumu yomoya iyonke igcinwe inkulu kuneisilindaivolumu yamanzi. Ifomula yokubala ivolumu yomoya ogciniweyo:

Umzekelo, ukuba aisilindauneUmthamo wamanzi weelitha ezi-6.8kwaye aUxinzelelo olusebenzayo lwe-300 bar, ivolumu yomoya ekhoyo:

 Oku kuthetha ukuba kwi-Atmospic uxinzelelo (i-1 bar), iisilindaIne-2040 yeelitha zomoya.

Inyathelo 2: Cinga ngenqanaba lokuphefumla

Ixesha lokubonelela ngomoya kuxhomekeke kwixabiso lokuphefumla lomsebenzisi, lihlala lilinganiswe ngaphakathiiilitha ngomzuzu (l / min). Kwisicelo sokucima umlilo kunye nezicelo ze-SCBA, izinga lokuphefumla okuqhelekileyo zokuphefumlaI-20 l / min, ngelixa inza nzima enzima inokunyusa40-50 l / min okanye ngaphezulu.

Inyathelo 3: Bala ixesha

Ixesha lokuhambisa umoya libaliwe ukusebenzisa:

Ngomcimi-mlilo usebenzisa umoya kwiI-40 l / min:

Umntu ophumle usebenzisaI-20 l / min:

Ke, ixesha lahluka ngokuxhomekeke kwinqanaba lomsebenzisi.

Ezinye izinto ezichaphazela ixesha lomoya

1. IsilindaGcina uxinzelelo: Izikhokelo zoKhuseleko zihlala zincoma ukugcina indawo yokugcina indawo yokuhlalaI-50 bar, ukuqinisekisa umoya owoneleyo wokusetyenziswa kaxakeka. Oku kuthetha ukuba ivolumu yomoya esebenzayo iphantsi kancinci kunokuba ngumthamo opheleleyo.
2. UMGAQO-NKQUBO WEENKONZO: Umlawuli ulawula ukuhamba komoya ukusuka kwiisilinda, kwaye iimodeli ezahlukeneyo zinokuchaphazela ukusetyenziswa komoya.
3. Iimeko zeNdalo: Amaqondo obushushu aphezulu anokunyuka kancinci uxinzelelo lwangaphakathi, ngelixa iimeko ezibandayo zinokuncipha.
4. Iipateni zokuphefumlaUkuphefumla okungaphantsi okanye okulawulwa kunokunyusa ukubonelelwa ngomoya, ngelixa ukuphefumla ngokukhawuleza kuyinciphisa.

Izicelo ezisebenzayo

• Umlilo wokucima umlilo: UkwaziisilindaIxesha elinceda ekucwangciseni iindlela ezikhuselekileyo zokuphuma kunye nokuphuma ngexesha lokuhlangula.
• Abasebenzi bezoMveliso: Abasebenzi kwiindawo ezinobungozi baxhomekeke kwiiSba iinkqubo apho ulwazi oluchanekileyo lomoya lubalulekile.
• Eyahlukileyo: Ukubalwa okufanayo kuya kufaka useto olungaphantsi kwamanzi, apho ukubeka iliso kulawulo lomoya kubalulekile ukhuseleko.

Ukuqukumbela

Ngokuqonda ivolumu yamanzi, uxinzelelo lokusebenza, kunye nenqanaba lokuphefumla, abasebenzisi banokuqikelela ukuba i-aI-carbon fiber cylinderziya kubonelela ngomoya. Olu lwazi lubalulekile ukuze ukhuseleke kunye nokusebenza kakuhle kwizicelo ezahlukeneyo. Ngelixa ukubala kubonelela ngoqikelelo uqoqosho ngokubanzi, iimeko zokwenyani ezinjengeereyitha zokuphefumla, ukusebenza komthetho, kunye nokugcina izinto eziqwalaselwayo nazo kufuneka zithathelwe ingqalelo.
