Chii chinonzi SCBA Matangi Anozadzwa Ne?

Self-Contained Breathing Apparatus (SCBA) tanks zvakakosha midziyo yekuchengetedza inoshandiswa mumaindasitiri akasiyana siyana, kusanganisira kudzima moto, mabasa ekununura, uye kubata zvinhu zvine njodzi. Aya matangi anopa mweya unofema kune vashandisi vanoda kushanda munzvimbo dzine mhepo ine hutachiona kana mazinga eokisijeni akadzikira zvine njodzi. Kunzwisisa chiiSCBA tanks anozadzwa nazvo uye zvinhu zvinoshandiswa kuzvivaka zvakakosha pakutenda mashandiro awo uye nekuona kuti anoshandiswa zvinobudirira munjodzi.

ChiiSCBA Tangis Contain

SCBA tanks, inozivikanwawo semasilinda, yakagadzirirwa kuchengetedza uye kupa mweya wakamanikidzwa kana oxygen kune anopfeka. Heino kutarisisa kwakadzama kwezviri mukati uye kuvaka kweaya matangi:

1. Air Compressed

ZvizhinjiSCBA tanks inozadzwa nemhepo yakamanikidzwa. Mhepo yakadzvanywa imhepo yakamanikidzwa kusvika padanho repamusoro pane mhepo yemhepo. Kudzvanyirira uku kunobvumira huwandu hwakakosha hwemhepo kuti huchengetwe mutangi diki, zvichiita kuti ishandiswe kushandiswa mumamiriro akasiyana. Air compressed mukatiSCBA tanks kazhinji inosanganisira:

• Okisijeni:Inenge 21% yemhepo iokisijeni, inova chikamu chimwechete chinowanikwa mumhepo pagungwa.
• Nitrogen nemamwe magasi:Iyo 79% yasara inoumbwa nenitrogen uye kutsvaga huwandu hwemamwe magasi anowanikwa mumhepo.

The compressed air inSCBA tanks inocheneswa kubvisa tsvina, kuve nechokwadi kuti yakachengeteka pakufema kunyangwe munzvimbo dzakasvibiswa.

2. Okisijeni yakamanikidzwa

Mune mamwe masisitimu eSCBA akasarudzika, matangi anozadzwa neyakaomeswa okisijeni panzvimbo yemhepo. Aya mayuniti anoshandiswa mune chaiwo mamiriro apo huwandu hwepamusoro hweokisijeni hunodiwa kana uko hunhu hwemhepo hwakakanganiswa zvakanyanya. Okisijeni yakamanikidzwa inowanzoshandiswa mu:

• Zvekurapwa Emergency:Iko kwakachena oxygen inogona kudiwa kune varwere vane nyaya dzekufema.
• High Altitude Operations:Uko mwero weokisijeni wakadzikira, uye kuwanda kweokisijeni kunobatsira.

Kuvakwa kweSCBA Tangis

SCBA tanks dzakagadzirirwa kutsungirira kudzvinyirirwa kwakakwirira uye mamiriro akaoma. Kusarudzwa kwezvinhu zvinoshandiswa pakuvaka matangi aya kwakakosha pakuita kwavo nekuchengetedza.Carbon fiber composite silindas isarudzo yakakurumbira nekuda kwehukuru hwavo zvivakwa. Heino kunyatsotarisisa pazvinhu izvi:

1. Carbon Fiber Composite Cylinders

Carbon fiber composite silindas anoshandiswa zvakanyanya muSCBA masisitimu nekuda kwesimba rawo uye huremu hwezvinhu. Zvinhu zvikuru zvemasilinda aya zvinosanganisira:

• Inner Liner:Iyo yemukati liner yehumburumbira, inowanzo gadzirwa kubva kuzvinhu zvakaita sealuminium kana plastiki, inobata mweya wakamanikidzwa kana oxygen.
• Carbon Fiber Kuputira:Iyo yekunze yehumburumbira inogadzirwa kubva kucarbon fiber composite zvinhu. Carbon fiber chinhu chakasimba, chakareruka chinopa yakakwira simba-ku-huremu reshiyo uye kuramba kukanganiswa uye ngura.

Zvakanakira zveCarbon Fiber Composite Cylinders:

• Huremu: Carbon fiber cylinders dzakareruka zvakanyanya kana zvichienzaniswa nesimbi yechinyakare kana masilinda ealuminium. Izvi zvinoita kuti zvive nyore kutakura uye kubata, izvo zvinonyanya kukosha mumamiriro epamusoro-soro semoto kana mabasa ekununura.
• High Strength:Pasinei nekureruka,carbon fiber composite silindas dzakasimba zvisingaite uye dzinogona kumira kumanikidzwa kwakanyanya. Izvi zvinovimbisa kuti silinda inogona kuchengetedza mweya wakamanikidzwa kana oxygen pasina njodzi yekutsemuka.
• Durability:Carbon fiber inopesana nekuora uye kukuvara kubva kune zvakatipoteredza. Izvi zvinowedzera hupenyu hurefu hwema cylinders, zvichiita kuti avimbike kunyange mumamiriro ezvinhu akaoma.
• Kubudirira:Magadzirirwo ecarbon fiber cylinders inovabvumira kuchengetedza mweya wakawanda kana oxygen munzvimbo diki, ichipa vashandisi michina yekufema yakawanda uye inoshanda.

2. Zvimwe Zvishandiso

• Aluminium Liner:VamweSCBA tanks shandisa aluminium liner, iyo yakareruka kupfuura simbi uye inopa kurwisa kwakanaka pakuora. Aya matangi anowanzo kuputirwa nechinhu chakaumbwa, senge fiberglass kana kabhoni fiber, kuwedzera simba ravo.
• Matangi esimbi:Traditional SCBA matangi anogadzirwa kubva simbi, iyo yakasimba asi inorema kupfuura aruminiyamu kana zvinhu zvakaumbwa. Matangi esimbi achiri kushandiswa mune mamwe maapplication asi zvishoma nezvishoma ari kutsiviwa nemamwe akareruka.

Kuchengetedza uye Kuchengetedza

KuvimbisaSCBA tanks inozadzwa nemazvo uye inochengetwa nemazvo yakakosha pakuchengetedza uye kuita:

• Kugara Kuongorora: SCBA tanks inofanira kuongororwa nguva dzose kune zviratidzo zvekupfeka kana kukuvara. Izvi zvinosanganisira kutarisisa kuti hapana mazino here, pakatsemuka, kana zvimwe zvinhu zvinogona kukanganisa kuvimbika kwetangi.
• Hydrostatic Testing: SCBA tanks inofanirwa kuongororwa nguva nenguva ye hydrostatic kuyedzwa kuti ive nechokwadi chekuti vanogona kumirisana nedzvinyiriro huru yavakagadzirirwa. Izvi zvinosanganisira kuzadza tangi nemvura nekuidzvanya kuti itarise kana ichidonha kana kusasimba.
• Kuzadza Kwakakodzera:Matangi anofanirwa kuzadzwa nenyanzvi dzakadzidziswa kuti ave nechokwadi chekuti mhepo kana okisijeni yakatsikirirwa kune chaiyo kudzvanywa uye kuti tangi yakachengeteka kushandisa.

Mhedziso

SCBA tanks inoita basa rakakosha mukupa mweya unofema kana oxygen munzvimbo dzine njodzi. Kusarudzwa kwezvinhu zvematangi aya kunokanganisa zvakanyanya kuita kwavo.Carbon fiber composite masilindadzave sarudzo yakakurumbira nekuda kwehuremu hwadzo, simba repamusoro, uye kusimba. Ivo vanopa mabhenefiti akakosha pamusoro pechinyakare simbi kana aruminiyamu matangi, anosanganisira nyore kubata uye kuchengetedzwa kwakagadziridzwa. Kugara kugadziridzwa uye kubata kwakaringana kweaya matangi kunovimbisa kuvimbika kwavo uye kushanda, zvichiita kuti ave akakosha pakuchengetedza mune dzakasiyana siyana dzekukurumidzira uye maindasitiri.
