Ibala Isikhathi Sokuhlinzeka Ngomoya Sesilinda Se-Carbon Fiber

Isingeniso

I-carbon fibre cylinderama-s asetshenziswa kakhulu ezimbonini ezahlukahlukene, kufaka phakathi izicishamlilo, i-SCBA (imishini yokuphefumula equkethwe yona), ukutshuza, kanye nezicelo zezimboni. Into eyodwa ebalulekile kubasebenzisi ukwazi ukuthi ishaje ngokugcwele isikhathi esingakananiisilindaanganikeza umoya. Lesi sihloko sichaza ukuthi ungabalwa kanjani ubude bokunikezwa komoya ngokusekelwe ku-isilindaumthamo wamanzi, ingcindezi yokusebenza, nezinga lokuphefumula lomsebenzisi.

UkuqondaI-Carbon Fiber Cylinders

Isilinda esiyinhlanganisela ye-carbon fibres aqukethe i-liner yangaphakathi, ngokuvamile eyenziwe nge-aluminium noma ipulasitiki, esongwe ngezingxenye ze-carbon fiber ukuze uthole amandla engeziwe. Zenzelwe ukubamba umoya ocindezelweyo ezicindezelweni eziphezulu kuyilapho zihlala zilula futhi zihlala isikhathi eside. Izicaciso ezimbili eziyinhloko ezithonya ubude besikhathi sokuhlinzekwa komoya yilezi:

• Umthamo Wamanzi (Amalitha): Lokhu kubhekisela kumthamo wangaphakathi we-isilindalapho igcwele uketshezi, nakuba isetshenziselwa ukunquma isitoreji somoya.
• Ingcindezi Yokusebenza (Ibha noma i-PSI): Ingcindezi lapho iisilindaigcwele umoya, ngokuvamile ibha engu-300 (4350 psi) yezinhlelo zokusebenza ezinomfutho ophezulu.

Isinyathelo Ngesinyathelo Ukubalwa Kwesikhathi Sokuhlinzeka Ngomoya

Ukunquma ukuthi isikhathi esingakanani aci-arbon fibre cylinderinganikeza umoya, landela lezi zinyathelo:

Isinyathelo 1: Thola Ivolumu Yomoya ku-Isilinda

Njengoba umoya ucindezelwa, ingqikithi yomoya ogciniwe inkulu kune-isilindaumthamo wamanzi 's. Ifomula yokubala ivolumu yomoya egciniwe ithi:

Isibonelo, uma aisilindaunayo aumthamo wamanzi 6.8 amalithakanye aingcindezi yokusebenza ye-300 bar, ivolumu yomoya etholakalayo ithi:

 Lokhu kusho ukuthi ekucindezelweni komkhathi (1 ibha), iisilindaiqukethe amalitha angu-2040 omoya.

Isinyathelo sesi-2: Cabangela Izinga Lokuphefumula

Ubude besikhathi sokuhlinzekwa komoya buncike esilinganisweni sokuphefumula somsebenzisi, esivame ukukalwa ngoamalitha ngomzuzu (L/min). Kuzinhlelo zokusebenza zokucisha umlilo kanye ne-SCBA, izinga lokuphefumula elijwayelekile liwukuthi20 L/min, kuyilapho ukuzikhandla okukhulu kungakwandisa ku40-50 L/min noma ngaphezulu.

Isinyathelo sesi-3: Bala ubude besikhathi

Ubude besikhathi sokuhlinzekwa komoya bubalwa kusetshenziswa:

Ukuze isicishamlilo usebenzisa umoya at40 L/min:

Okomuntu ophumule usebenzisa20 L/min:

Ngakho, ubude besikhathi buyahlukahluka kuye ngezinga lomsebenzi womsebenzisi.

Ezinye Izinto Ezithinta Ubude Besikhathi Somoya

1. IsilindaReserve Pressure: Imihlahlandlela yokuphepha ivamise ukutusa ukugcina indawo ebekiwe, ngokuvamile eseduze50 ibha, ukuze kuqinisekiswe umoya owanele wokusetshenziswa okuphuthumayo. Lokhu kusho ukuthi umthamo womoya osebenzisekayo ungaphansi kancane kunomthamo ogcwele.
2. Ukusebenza Kwesilawuli: Isilawuli silawula ukugeleza komoya kusuka ku-isilinda, namamodeli ahlukene angase athinte ukusetshenziswa komoya kwangempela.
3. Izimo Zemvelo: Amazinga okushisa aphezulu angakhuphula kancane ukucindezela kwangaphakathi, kuyilapho izimo ezibandayo zingase zehlise.
4. Amaphethini wokuphefumula: Ukuphefumula okungajulile noma okulawulwayo kunganweba ukutholakala komoya, kuyilapho ukuphefumula ngokushesha kuyawehlisa.

Izicelo Ezisebenzayo

• Izicishamlilo: Ukwaziisilindaubude besikhathi busiza ekuhleleni amasu okungena okuphephile nokuphuma ngesikhathi semisebenzi yokuhlenga.
• Abasebenzi Bezimboni: Abasebenzi abasezindaweni eziyingozi bathembele ezinhlelweni ze-SCBA lapho ulwazi olunembile lwesikhathi somoya lubalulekile.
• Abatshuzi: Izibalo ezifanayo ziyasebenza kuzilungiselelo ezingaphansi kwamanzi, lapho ukuqapha ukuhlinzekwa komoya kubalulekile ukuze kuphephe.

Isiphetho

Ngokuqonda umthamo wamanzi, ingcindezi yokusebenza, nezinga lokuphefumula, abasebenzisi bangalinganisela ukuthi isikhathi esingakanani ai-carbon fibre cylinderizonikeza umoya. Lolu lwazi lubalulekile ekuphepheni nasekusebenzeni kahle ezinhlelweni ezahlukene. Nakuba izibalo zinikeza isilinganiso esivamile, izimo zomhlaba wangempela ezifana nokuguquguquka kwezinga lokuphefumula, ukusebenza kwesilawuli, nokucatshangelwa komoya wokulondoloza kufanele kucatshangelwe.
