Momwe Mungawerengere Mphamvu ya SCBA Cylinder: Kumvetsetsa Nthawi Yogwira Ntchito ya Carbon Fiber Cylinders

Self-Contained Breathing Apparatus (SCBA) silindas ndizofunikira kwambiri popereka mpweya wopuma kwa ozimitsa moto, ogwira ntchito yopulumutsa anthu, ndi ena ogwira ntchito m'malo owopsa. Kudziwa nthawi yayitali bwanjiSCBA silindakukhazikika pakagwiritsidwa ntchito ndikofunikira pokonzekera ntchito ndikuwonetsetsa chitetezo. Kutalika kwa ntchito ya silinda kumadalira kuchuluka kwake, kupanikizika, komanso kupuma kwa wogwiritsa ntchito. Nkhaniyi ikutsogolerani momwe mungawerengere mphamvu yaSCBA silinda, pogwiritsa ntchito njira yosavuta, ndi chidwi chapaderacarbon fiber composite silindas, omwe amagwiritsidwa ntchito kwambiri chifukwa cha kupepuka kwawo komanso mphamvu zawo.

SCBA CylinderZoyambira: Voliyumu ndi Kupanikizika

SCBA silindas sungani mpweya woponderezedwa kwambiri, womwe umayesedwa m'mipiringidzo kapena mapaundi pa inchi imodzi (PSI). Kuchuluka kwa mpweya mkati mwa silinda nthawi zambiri kumawonetsedwa mu malita. Zinthu ziwiri zazikulu zomwe zimatsimikizira kuchuluka kwa mpweya womwe ulipo ndi:

• Cylinder Volume: Ichi ndi kukula kwa mkati mwa silinda, nthawi zambiri kufotokozedwa mu malita (mwachitsanzo, 6.8-lita kapena 9-lita).
• Cylinder Pressure: Kupanikizika komwe mpweya umasungidwa, nthawi zambiri pakati pa 200 ndi 300 barSCBA silindas.

Silinda ya carbon fiber composites ndi otchuka mu machitidwe a SCBA chifukwa amapereka mphamvu yothamanga kwambiri (mpaka 300 bar) pamene imakhala yopepuka kwambiri kuposa zitsulo zachikhalidwe kapena ma silinda a aluminiyamu. Izi zimawapangitsa kukhala abwino nthawi yomwe ogwiritsa ntchito amafunika kuyenda mwachangu kapena kwanthawi yayitali.

The Fomula Yowerengera Nthawi ya SCBA

Nthawi yogwira ntchito ya anSCBA silindazitha kuwerengedwa pogwiritsa ntchito njira iyi:

• "40" mu fomulayi ikuyimira kupuma kwapakati kwa munthu yemwe ali pansi pa ntchito zochepa. Mlingo uwu ukhoza kusiyanasiyana malinga ndi momwe wogwiritsa ntchito akugwirira ntchito, koma malita 40 pamphindi (L / min) ndi chiwerengero chokhazikika.
• "-10" kumapeto kwa chilinganizo ndi malire achitetezo, kuonetsetsa kuti wogwiritsa ntchito ali ndi nthawi yotuluka pamalo owopsa mpweya usanathe.

Kuwerengera Chitsanzo:

Tiyeni tiwerengere nthawi yogwira ntchito ya 6.8-litampweya CHIKWANGWANI SCBA yamphamvu, wopanikizidwa mpaka 300 bar.

Mu chitsanzo ichi, aSCBA silindaangapereke mpweya wopuma pafupifupi mphindi 35 musanafunike kusinthidwa kapena kuwonjezeredwa. Kuwerengeraku kumatengera masewera olimbitsa thupi pang'ono, ndipo nthawi yeniyeni yogwiritsira ntchito ingasiyane ngati wogwiritsa ntchito akuyesetsa mochulukirapo kapena mochepera.

Zinthu AffekuchitaSCBA CylinderKutalika

Ngakhale kuti ndondomekoyi imapereka chiŵerengero choyambirira, pali zinthu zingapo zomwe zingakhudze

nthawi yeniyeni ya anSCBA silindamukugwiritsa ntchito. Kumvetsetsa zosinthazi ndikofunikira pakuwonetsetsa kuti ntchito zikuyenda bwino.

1. Mlingo wa kupuma

Fomula imatengera kupuma kwapakati

Hing mlingo wa 40 L/mphindi, amene amafanana ndi ntchito zolimbitsa. M'malo mwake, kupuma kumatha kusinthasintha malinga ndi kuchuluka kwa ntchito ya wogwiritsa ntchito:

• Zochita Zochepa: Ngati wogwiritsa ntchito akupumula kapena akugwira ntchito yopepuka, mpweya wopuma ukhoza kukhala wotsika, pafupifupi 20-30 L / min, zomwe zingatalikitse nthawi ya silinda.
• Ntchito Yapamwamba: Panthawi yochita masewera olimbitsa thupi, monga kulimbana ndi moto kapena kupulumutsa anthu, kupuma kumatha kufika ku 50-60 L / min kapena kuposa, kuchepetsa nthawi ya silinda.

2. Cylinder Pressure

Ma cylinders apamwamba amapereka mpweya wochuluka wa voliyumu yomweyo.Carbon fiber cylinders nthawi zambiri imagwira ntchito mokakamiza mpaka mipiringidzo 300, poyerekeza ndi masilinda achitsulo kapena aluminiyamu, omwe amatha kukhala ma bar 200 okha. Kuthamanga kwapamwamba kumalolampweya wa carbon fiber cylinders kusunga mpweya wambiri mu phukusi laling'ono, lopepuka, kukulitsa nthawi yogwira ntchito.

3. Mphepete mwa Chitetezo

Mphepete mwachitetezo chomangidwa mu chilinganizo (-10 mphindi) imatsimikizira kuti

wogwiritsa ntchito samatha mpweya akadali pamalo owopsa. Ndikofunika kulemekeza chotchinga ichi powerengera nthawi yogwira ntchito ndikukonzekera kugwiritsa ntchito mpweya, makamaka pamene njira yotuluka ingatenge mphindi zingapo kuti idutse.

T

iye Udindo waCarbon Fiber Composite Cylinders

Silinda ya carbon fiber composites akhala chisankho chokondeka pamakina a SCBA chifukwa cha kapangidwe kawo kopepuka komanso kuthekera kosunga zopinga zambiri. Poyerekeza ndi masilindala achitsulo ndi aluminiyamu,mpweya wa carbon fiber cylinders amapereka maubwino angapo:

• Kulemera: Carbon fiber cylinders ndizopepuka kwambiri kuposa zitsulo, zomwe zimapangitsa kuti zikhale zosavuta kunyamula komanso kuchepetsa kutopa kwa wogwiritsa ntchito panthawi yayitali.
• Kupanikizika Kwambiri: Amatha kudzazidwa ndi zokakamiza mpaka 300 bar, kupereka mpweya wochulukirapo popanda kuwonjezera kukula kwa silinda.
• Kukhalitsa: Zophatikizika za kaboni fiber ndi zamphamvu kwambiri, zimatha kupirira kupsinjika kwambiri komanso kugonjetsedwa ndi zovuta komanso zachilengedwe.

Mapangidwe opepuka ndi ofunikira kwambiri kwa ogwira ntchito yopulumutsa omwe amafunika kukhalabe oyenda pamene akunyamula zida zina, monga zida zozimitsa moto kapena zida zamankhwala. Ngakhale zabwino zake,mpweya wa carbon fiber cylinders amabwera ndi zofunikira zina zokonzetsera, monga kuyezetsa pafupipafupi kwa hydrostatic kuwonetsetsa kuti amakhala otetezeka akapanikizika.

Kuyeza kwa Hydrostatic ndiSCBA CylinderKusamalira

Kusunga kudalirika kwaSCBA silindas, kuphatikiza mitundu ya kaboni fiber, kukonza pafupipafupi ndikofunikira. Izi zikuphatikizapo:

• Zoyendera Zowoneka: Yang'anani zowonongeka, monga ming'alu kapena mano, musanagwiritse ntchito.
• Kuyeza kwa Hydrostatic: Mpweya wa carbonSCBA silindas amafunikira kuyezetsa kwa hydrostatic zaka zisanu zilizonse kuti atsimikizire kuti atha kuthana ndi zovuta zomwe zimakhudzidwa. Chiyesochi chimayang'ana kukula kulikonse kwa silinda komwe kungasonyeze kufooka kwa zinthu.
• Kusintha: Ngakhale ndikusamalidwa bwino,mpweya CHIKWANGWANI SCBA yamphamvus amakhala ndi nthawi yayitali, nthawi zambiri pafupifupi zaka 15, pambuyo pake ayenera kusinthidwa.

Mapeto

Kudziwa kuwerengera mphamvu ndi nthawi yogwira ntchitoSCBA silindas ndi

ndizofunikira kwa aliyense amene amadalira zidazi m'malo owopsa. Kugwiritsa ntchito fomula(Volume × Pressure) / 40 - 10, inu can yerekezerani nthawi yomwe ilipo mu silinda iliyonse, pokumbukira kuti kupuma, kupanikizika, ndi malire a chitetezo zonse zimagwira ntchito pamapeto omaliza.

Silinda ya carbon fiber composites, ndi kapangidwe kawo kopepuka komanso kuthekera kosunga zopinga zambiri, ndizosankha zodziwika bwino pamakina a SCBA. Amapereka nthawi yayitali yogwira ntchito komanso kuyenda bwino poyerekeza ndi masilinda achitsulo kapena aluminiyamu. Komabe, kukonza nthawi zonse, kuphatikiza kuyang'ana kowoneka ndi kuyezetsa kwa hydrostatic, ndikofunikira kuti zitsimikizire kuti masilindalawa amakhala otetezeka komanso ogwira mtima pa moyo wawo wonse wautumiki.

Kumvetsetsa mbali izi zaSCBA silindamphamvu idzathandiza kuonetsetsa kuti ikugwiritsidwa ntchito motetezeka komanso mogwira mtima m'malo ovuta, pomwe mphindi iliyonse ya mpweya wopuma imatha kusintha.
