Ukubala isikhathi sokuhlinzeka ngomoya wesilinda se-carbon fiber

Ukuqalisa

Isilinda se-carbon fiberIsetshenziswa kabanzi kwizimboni ezahlukahlukene, kufaka phakathi ukucisha umlilo, i-SCBA (izinto zokuphefumula ezinazo), ukudonsa kanye nezicelo zezimboni. Isici esisodwa esibalulekile sabasebenzisi sazi ukuthi kuphethwe isikhathi esingakananiisilindaingahambisa umoya. Lo mbhalo uchaza ukuthi ungabala kanjani isikhathi sokuhlinzeka ngomoya ngokususelwa kuisilindaIvolumu yamanzi, ingcindezi yokusebenza, kanye nesilinganiso sokuphefumula komsebenzisi.

-ZwayoIsilinda se-carbon fibers

I-Carbon fiber Composite CylinderInhlanganisela i-liner engaphakathi, okwenziwe nge-aluminium noma ipulasitiki, esongwe izingqimba ze-carbon fiber ngamandla angeziwe. Zenzelwe ukubamba umoya ocindezelwe ngokucindezela okuphezulu ngenkathi kusele ezingasindi futhi zihlala isikhathi eside. Imininingwane emibili eyinhloko ethonya isikhathi sokuhlinzekwa komoya yile:

• Ivolumu yamanzi (amalitha): Lokhu kusho amandla angaphakathi weisilindalapho kugcwele uketshezi, yize kusetshenziselwa ukuthola isitoreji somoya.
• Ingcindezi Yomsebenzi (ibha noma i-PSI): Ingcindezi laphoisilindaIgcwele umoya, imvamisa i-300 Bar (4350 PSI) yezicelo eziphakeme kakhulu.

Ukubalwa kwesinyathelo ngesinyathelo isikhathi sokuhlinzekwa komoya

Ukunquma ukuthi isikhathi esingakanani i-ACisilinda se-arbon fiberAnganikeza umoya, landela lezi zinyathelo:

Isinyathelo 1: Thola ivolumu yomoya kuIsilinda

Njengoba umoya ungcolile, ivolumu yomoya ephelele igcinwe inkulu kuneisilindaivolumu yamanzi. Ifomula yokubala ivolumu yomoya egciniwe yile:

Isibonelo, uma aisilindaineumthamo wamanzi wamalitha ayi-6.8kanye aIngcindezi Yomsebenzi ka-300 Bar, ivolumu yomoya etholakalayo yile:

 Lokhu kusho ukuthi ekucindezelweni komkhathi (ibha 1),isilindaKuqukethe amalitha angama-2040 womoya.

Isinyathelo 2: Cabanga ngesilinganiso sokuphefumula

Isikhathi sokuhlinzekwa komoya sincike emazingeni okuphefumula womsebenzisi, ngokuvamile alinganiswa ngaphakathiamalitha ngomzuzu (l / min). Ezinsizakalweni zokucima umlilo kanye ne-SCBA, isilinganiso esijwayelekile sokuphumula sokuphumula20 l / min, ngenkathi ukuzikhandla okunamandla kungakhulisa40-50 l / Min noma ngaphezulu.

Isinyathelo 3: Bala Isikhathi

Isikhathi sokuhlinzekwa komoya sibalwa kusetshenziswa:

Okwesikhashana usebenzisa umoya ku-40 l / min:

Okomuntu ekuphumuleni esebenzisa20 l / min:

Ngakho-ke, isikhathi siyahluka ngokuya ngezinga lomsebenzi womsebenzisi.

Ezinye izinto ezithinta isikhathi somoya

1. IsilindaUmfutho wokugcina: Imihlahlandlela Yezokuphepha ivame ukuncoma ukugcina ukubhuka, ngokujwayelekileIbha ye, ukuqinisekisa umoya owanele wokusetshenziswa okuphuthumayo. Lokhu kusho ukuthi ivolumu yomoya esebenzisekayo ingaphansi kwamandla aphelele.
2. Ukusebenza kahle koMlawuli: Umlawuli ulawula ukuhamba komoya kusuka kuisilinda, futhi amamodeli ahlukene angathinta ukusetshenziswa komoya kwangempela.
3. Izimo zezemvelo: Amazinga okushisa aphezulu angakhulisa kancane ingcindezi yangaphakathi, kanti izimo ezibandayo zinganciphisa.
4. Amaphethini okuphefumula: Ukuphefumula okungajulile noma okulawulwayo kunganweba ukunikezwa komoya, ngenkathi ukuphefumula okusheshayo kwehlisa.

Izicelo Ezisebenzayo

• Abafanduzayo: UkwaziisilindaIsikhathi sisiza ekuhleleni ukungena okuphephile kanye namasu okuphuma ngesikhathi sokutakula.
• Izisebenzi zezimboni: Abasebenzi ezindaweni eziyingozi bathembela ezinhlelweni ze-SCBA lapho ulwazi olunembile lomoya lwesikhathi lubalulekile.
• Divori: Izibalo ezifanayo zisebenza kuzilungiselelo ezingaphansi kwamanzi, lapho ukubhekelwa komoya kubalulekile ukuphepha.

Ukugcina

Ngokuqonda ivolumu yamanzi, ingcindezi yokusebenza, kanye nezinga lokuphefumula, abasebenzisi bangalinganisa ukuthi aisilinda se-carbon fiberizonikela ngomoya. Lolu lwazi lubalulekile ukuphepha kanye nokusebenza kahle kwizicelo ezahlukahlukene. Ngenkathi izibalo zihlinzeka ngokulinganisa okujwayelekile, izimo zangempela zomhlaba njengokushintshashintsha kwesilinganiso sokuphefumula, ukusebenza koMlawuli, kanye nokugcinwa komoya kufanele kubhekwe.
