Maverengero eSCBA Cylinder Capacity: Kunzwisisa Nguva Yekushanda yeCarbon Fiber Cylinders

Self-Contained Breathing Apparatus (SCBA) silindas yakakosha pakupa mweya unofema kune vanodzima moto, vashandi vekununura, uye vamwe vashandi vanoshanda munzvimbo dzine njodzi. Kuziva kuti kwenguva yakareba seiSCBA humburumbiraichagara panguva yekushandiswa kwakakosha pakuronga mashandiro uye kuve nechokwadi chekuchengetedza. Nguva yekushanda yecylinder inoenderana nehuwandu hwayo, kudzvanywa, uye kufema kwemushandisi. Ichi chinyorwa chichakufambisa iwe kuburikidza maitiro ekuverenga huwandu hweSCBA humburumbira, uchishandisa nzira yakapfava, ine hanya zvikurucarbon fiber composite silindas, ayo anoshandiswa zvakanyanya nekuda kwekureruka kwawo uye simba.

SCBA CylinderBasics: Volume uye Pressure

SCBA humburumbiras chitoro chakadzvanywa mweya pakumanikidzwa kukuru, kazhinji kuyerwa mumabhawa kana mapaundi paskweya inch (PSI). Uwandu hwemhepo mukati mehumburumbira inowanzoratidzwa mumarita. Zvinhu zviviri zvikuru zvinotaridza kuti mhepo yakawanda sei iripo ndeiyi:

• Cylinder Volume: Uyu ndiwo hukuru hwemukati we cylinder, inowanzoratidzwa mumatita (eg, 6.8-liter kana 9-liter).
• Cylinder Pressure: Kudzvanywa kunochengetwa mhepo, kazhinji pakati pe200 ne300 bar yeSCBA humburumbiras.

Carbon fiber composite silindas dzinofarirwa muSCBA masisitimu nekuti dzinopa yakakwira kudzvanywa simba (kusvika 300 bar) ichireruka zvakanyanya kupfuura yechinyakare simbi kana aruminiyamu silinda. Izvi zvinovaita kuti vakwanise kumamiriro ezvinhu apo vashandisi vanoda kufamba nekukurumidza kana kwenguva yakareba.

The Formula yeKuverengera SCBA Nguva

Nguva yekushanda yeSCBA humburumbirainogona kuverengerwa uchishandisa inotevera formula:

• Iyo "40" mufomula inomiririra avhareji yekufema kwemunhu ari pasi pemamiriro ekushanda ane mwero. Chiyero ichi chinogona kusiyana zvichienderana nekuti mushandisi ari kushanda nesimba sei, asi marita makumi mana paminiti (L/min) inhamba yakajairwa.
• Iyo "-10" pakupera kweformula inzvimbo yekuchengetedza, kuve nechokwadi kuti mushandisi ane nguva yekubuda munzvimbo ine njodzi mweya usati wapera zvachose.

Muenzaniso Kuverengera:

Ngativerengei nguva yekushanda ye6.8-litrekabhoni faibha SCBA humburumbira, yakamanikidzwa kusvika ku300 bar.

Mumuenzaniso uyu, theSCBA humburumbirayaizopa angangoita maminetsi makumi matatu nemashanu emweya unofema usati wada kutsiviwa kana kuzadzwa patsva. Kuverengera uku kunotora kuita kwemuviri kuri pakati nepakati, uye nguva chaiyo yekushandisa inogona kusiyana kana mushandisi ari kuzvishingisa zvakanyanya kana zvishoma.

Zvinhu AffectingSCBA CylinderDuration

Nepo fomula ichipa fungidziro yekutanga, zvinhu zvakati wandei zvinogona kukanganisa

nguva chaiyo ye anSCBA humburumbiramukushandiswa. Kunzwisisa izvi zvakasiyana-siyana kwakakosha pakuita mashandiro akachengeteka.

1. Kufema Mwero

Fomula yacho inotora kufema kwepakati

hing rate ye40 L / min, iyo inoenderana nepakati pekuita basa. Muchokwadi, mwero wekufema unogona kuchinjika zvichienderana nebasa remushandisi:

• Kuita kwakaderera: Kana mushandisi akazorora kana kuita basa rakareruka, mwero wekufema unogona kunge wakaderera, wakatenderedza 20-30 L/min, izvo zvaizowedzera nguva yehumburumbira.
• High Activity: Panguva yekurovedza muviri kunorema, sekurwisa moto kana kununura vanhu, kufema kunogona kuwedzera kusvika ku50-60 L/min kana kupfuura, kuderedza nguva yecylinder.

2. Cylinder Pressure

Higher pressure cylinders inopa mweya wakawanda wevhoriyamu imwechete.Carbon fiber cylinders anowanzo shanda nekumanikidza kusvika mazana matatu emabha, zvichienzaniswa nesimbi kana aruminiyamu macylinders, ayo anogona kuganhurirwa ku200 bar. Iyo yakanyanya kudzvinyirira inobvumiracarbon fiber cylinders kubata mweya wakawanda mudiki, reruka pasuru, uchiwedzera nguva yekushanda.

3. Safety Margin

Iyo yekuchengetedza margin yakavakirwa mufomula (-10 maminetsi) inovimbisa kuti iyo

mushandisi haapererwe nemhepo achiri munzvimbo ine njodzi. Zvakakosha kuremekedza iyi bafa paunenge uchiverenga nguva yekushanda uye kuronga mashandisirwo emhepo, kunyanya mumamiriro ezvinhu apo nzira yekubuda nayo inogona kutora maminetsi akati wandei kufamba.

T

iye Basa reCarbon Fiber Composite Cylinders

Carbon fiber composite silindas yave sarudzo inosarudzika yeSCBA masisitimu nekuda kwehuremu hwekugadzira uye kugona kubata zvakanyanya kumanikidza. Kuenzaniswa nesimbi uye aluminium silinda,carbon fiber cylinderinopa mabhenefiti akati wandei:

• Kurema: Carbon fiber cylinders dzakareruka zvakanyanya pane simbi, zvichiita kuti zvive nyore kutakura uye kuderedza kuneta kumushandisi panguva yekuwedzera maoparesheni.
• Higher Pressure: Vanogona kuzadzwa kumanikidziro kusvika ku300 bar, kupa mhepo yakawanda pasina kuwedzera kukura kwecylinder.
• Kugara kwenguva refu: Carbon fiber composites yakasimba zvakanyanya, inokwanisa kumirisana nedzvinyiriro yakanyanya uku ichiramba kukanganiswa uye zvakatipoteredza.

Iyo yakareruka dhizaini inonyanya kukosha kune vashandi vekununura vanoda kuramba vachifambisa pavanenge vakatakura zvimwe midziyo, senge maturusi ekudzima moto kana giya rekurapa. Pasinei nezvakanaka zvavo,carbon fiber cylinders dzinouya nezvimwe zvinodiwa zvekugadzirisa, senge nguva dzose hydrostatic yekuongorora kuti ive nechokwadi chekuti inoramba yakachengeteka pasi pekumanikidzwa.

Hydrostatic Testing uyeSCBA CylinderMaintenance

Kuchengetedza kuvimbika kweSCBA humburumbiras, kusanganisira kabhoni fiber modhi, kugadzirisa nguva dzose kwakakosha. Izvi zvinosanganisira:

• Visual Inspections: Tarisa kukuvara, senge makatsemuka kana dents, usati washandisa imwe neimwe.
• Hydrostatic Testing: Carbon fiberSCBA humburumbiras kazhinji inoda hydrostatic kuyedzwa makore mashanu ega ega kuti vaone kuti vanokwanisa kubata zvakanyanya kumanikidzwa. Muedzo uyu unotarisa chero kuwedzera mucylinder kunogona kuratidza kupera simba kwechinhu.
• Kutsiva:Kunyangwe nekugadziriswa kwakakodzera,kabhoni faibha SCBA humburumbiras vane hupenyu hune magumo, kazhinji makore gumi nemashanu, mushure mezvo vanofanirwa kutsiviwa.

Mhedziso

Kuziva maverengero ekugona uye kushanda nguva yeSCBA humburumbiras ndizvo

yakakosha kune chero munhu anovimba nemidziyo iyi munzvimbo dzine njodzi. Kushandisa formula(Vhoriyamu × Kudzvinyirira) / 40 - 10,iwe can fungidzira nguva inowanikwa muhumburumbira chero ipi zvayo, uchiyeuka kuti kufema kwekufema, kumanikidzwa, uye miganho yekuchengeteka zvose zvinoita basa munguva yekupedzisira.

Carbon fiber composite silindas, nedhizaini yavo isina huremu uye kugona kubata zvakanyanya, isarudzo yakakurumbira yeSCBA masisitimu. Vanopa nguva yakareba yekushanda uye kufamba kwakagadziridzwa zvichienzaniswa nesimbi kana aluminium cylinders. Nekudaro, kugadzirisa nguva dzose, kusanganisira kuongororwa kwekuona uye kuongororwa kwehydrostatic, kwakakosha kuti ive nechokwadi chekuti masilinda anoramba akachengeteka uye achishanda muhupenyu hwavo hwesevhisi.

Kunzwisisa zvinhu izvi zveSCBA humburumbirakugona kuchabatsira kuve nechokwadi chekushandisa kwakachengeteka uye kunoshanda munzvimbo dzakaoma, uko miniti yega yega yemhepo inofema inogona kuita mutsauko.
