Chii chinonzi Emergency Escape Breathing Device (EEBD)?

An Emergency Escape Breathing Device (EEBD) chinhu chakakosha chemidziyo yekuchengetedza yakagadzirirwa kushandiswa munzvimbo dzine mhepo ine njodzi, zvichiunza njodzi yekukurumidza kuhupenyu kana hutano. Midziyo iyi inowanzoshandiswa mumamiriro ezvinhu apo pane kamwe kamwe kusunungurwa kwemagasi ane chepfu, chiutsi, kana kushomeka kweokisijeni, zvichipa munhu akapfeka mweya wakakwana wekufema kuti atize zvakachengeteka munzvimbo ine ngozi.

MaEEBD anowanikwa mumaindasitiri akasiyana siyana, anosanganisira kutumira, migodhi, kugadzira, uye masevhisi ekukurumidzira, uye akagadzirirwa kupa dziviriro yenguva pfupi kune vanhu vari kutiza kubva munzvimbo ine njodzi pane kuti vashandise kwenguva refu. Kunyange zvisiri kuitirwa kudzima moto kana mabasa ekununura, maEEBD chinhu chakakosha chekuchengetedza chinogona kudzivirira kudzipwa kana chepfu kana sekondi yega yega ichiverenga. Chinhu chakakosha cheEEBDs yemazuva ano ndeyecarbon fiber composite silinda, iyo inoita basa rakakosha mukuita kuti zvishandiso zvireruke, zvigare, uye zvakavimbika mumamiriro ekukurumidzira.

Iyo EEBD Inoshanda sei

EEBD chinhu chakanyatso kufema chinopa mushandisi kupihwa kwemweya unofema kana oxygen kwenguva shoma, kazhinji pakati pe5 kusvika 15 maminetsi, zvichienderana nemuenzaniso. Chishandiso chiri nyore kushanda, kunyangwe pasi pekunetseka, uye chinowanzoitwa nekudhonza tabhu kana kuvhura mudziyo. Kana yangoitwa, mhepo kana oxygen inopa inotanga kuyerera ichienda kumushandisi, kungave kuburikidza nechiso chemeso kana muromo uye mhino clip system, kugadzira chisimbiso chinovadzivirira kubva mukufemesa magasi anokuvadza kana mweya usina oxygen.

Zvikamu zveEEBD

Izvo zvakakosha zvikamu zveEEBD zvinosanganisira:

• Kufema Cylinder: Silinda iyi inochengeta mweya wakatsikirirwa kana oxygen iyo mushandisi anofema panguva yekupukunyuka. MaEEBD emazuva ano ari kuwedzera kushandisa carbon fiber composite silindanekuda kwekureruka kwavo uye simba.
• Pressure Regulator+
• Face Mask kana Hood: Iyo maski kana hood inovhara kumeso kwemushandisi, ichipa chisimbiso chinochengeta kunze kwemagasi ane njodzi uchivabvumira kufema mumhepo kana oxygen inopihwa neEEBD.
• Harness kana Strap: Izvi zvinochengetedza mudziyo kumushandisi, zvichivatendera kuti vafambe vakasununguka vachipfeka EEBD.
• Alarm System: Mamwe maEEBD akashongedzerwa nealarm inorira kana mhepo ichipera, zvichiita kuti mushandisi akurumidze kutiza.

Carbon Fiber Composite Cylinders muEEBDs

Chimwe chezvinhu zvinonyanya kukosha zveEEBD icylinder yekufema, uye zvinhu zvinoshandiswa kune iyi silinda inoita basa guru mukushanda kwese kwechigadzirwa. MumaEEBD mazhinji emazuva ano,carbon fiber composite silindas anoshandiswa nekuda kwehukuru hwezvivakwa zvichienzaniswa nemidziyo yechinyakare sesimbi kana aluminium.

Lightweight Design

Imwe yemabhenefiti akakosha ecarbon fiber composite silindas ndiwo magadzirirwo avo akareruka. Mumamiriro ezvinhu ekukurumidzira, sekondi yega yega inoverengera, uye yakareruka EEBD inobvumira mushandisi kufamba nekukurumidza uye nekureruka kukuru. Carbon fiber composites yakareruka zvakanyanya kupfuura simbi nealuminium ichiri yakasimba zvakakwana kuti iwane mweya wakadzvanywa kana oxygen pakumanikidza kwakanyanya. Uku kuderedza uremu kunobatsira mushandisi kudzivirira kuneta, zvichiita kuti zvive nyore kutakura mudziyo panguva yekupukunyuka.

High Durability uye Simba

Carbon fiber composite silindas haisi kungoreruka chete asiwo yakasimba zvakanyanya uye yakasimba. Vanokwanisa kumirisana nedzvinyiriro huru inodiwa kuchengetedza mweya wakakwana kuti utize zvakachengeteka, uye vanoshingirira kukuvadzwa kubva mukukanganisa, ngura, uye kupfeka. Kusimba uku kwakakosha mumamiriro ezvinhu echimbichimbi apo mudziyo ungangobatwa zvisina kunaka, tembiricha yakanyanya, kana kusangana nemakemikari ane njodzi. Kusimba kwekabhoni fiber inobvumira silinda kuti irambe yakasimba uye inoshanda, kuve nechokwadi chekuti mushandisi ane yakavimbika mweya wekupa pavanenge vachiida zvakanyanya.

Kuwedzera Kugona

Imwe mukana wecarbon fiber composite silindas ndiko kugona kwavo kubata mweya wakawanda kana oxygen mupasuru diki, yakareruka. Uku kuwedzera kwesimba kunobvumira nguva refu yekutiza, ichipa vashandisi mamwe maminetsi emhepo inofema kuti vabude zvakachengeteka munzvimbo ine ngozi. Somuenzaniso, acarbon fiber composite silindainogona kupa mhepo yakafanana necylinder yesimbi asi ine huremu hushoma uye huremu, zvichiita kuti zvive nyore kushandiswa munzvimbo dzakavharirwa kana kune vashandisi vanoda kufamba nekukurumidza.

Kushandiswa kweEEBDs

MaEEBD anowanzoshandiswa mumaindasitiri umo vashandi vanogona kuratidzwa kune njodzi. Izvi zvinosanganisira:

• Maritime Industry: Pazvikepe, EEBD inowanzodiwa sechikamu chemidziyo yekuchengetedza. Kana pakaitika moto kana gasi radonha, vashandi vanogona kushandisa EEBD kutiza kubva mumakamuri einjini kana dzimwe nzvimbo dzakavharirwa uko mhepo inova nenjodzi.
• Mining: Migodhi inozivikanwa nemagasi ane njodzi uye nzvimbo dzakapera mweya weokisijeni. EEBD inopa vashandi vemumigodhi nzira yekukurumidza uye inotakurika yekutiza kana mhepo ikava isina kuchengetedzeka kufema.
• Industrial Plants: Mafekitari uye zvinomera zvinoshanda nemakemikari ane ngozi kana maitiro angada kuti vashandi vashandise maEEBD kana gasi rinoputika kana kuputika kunoitika, zvichitungamira kumhepo ine chepfu.
• Aviation: Dzimwe ndege dzinotakura maEEBDs kudzivirira nhengo dzevashandi nevafambi kubva pakufemerwa nehutsi kana kushomeka kweokisijeni muchiitiko chekukurumidzira mubhodhi.
• Indasitiri yeOiri neGasi: Vashandi vemunzvimbo dzinocheneswa oiri kana mapuratifomu ekuchera kumahombekombe kazhinji vanovimba neEEBD sechikamu chemidziyo yavo yekuzvidzivirira kuti vatize kubva pakubuda kwegasi kana moto.

EEBD vs. SCBA

Izvo zvakakosha kuti unzwisise musiyano uripo pakati peEEBD neSelf-Contained Breathing Apparatus (SCBA). Nepo zvese zvishandiso zvinopa mweya unofema mumhepo ine njodzi, zvakagadzirirwa zvinangwa zvakasiyana:

• EEBD: Basa rekutanga reEEBD nderekupa mhepo yenguva pfupi yekupa nekuda kwekupukunyuka. Haina kugadzirwa kuti ishandiswe kwenguva yakareba uye inowanzo shandirwa kukurumidza kubuda kubva munzvimbo dzine muchetura kana dzisina oxygen. MaEEBD anowanzo diki, akareruka, uye akatwasanuka kushanda pane maSCBA.
• SCBA: SCBA, kune rumwe rutivi, inoshandiswa kwenguva yakareba-yakareba, yakadai sekudzimisa moto kana kununura mishoni. Masisitimu eSCBA anopa mhepo yakawandisa, inowanzogara kusvika awa, uye akagadzirirwa kushandiswa munzvimbo dzine njodzi dzakawedzerwa. MaSCBA anowanza kuwanda uye akaomarara kupfuura maEEBD uye anosanganisira maficha epamusoro semajeji ekumanikidza, maaramu, uye zvinochinjika zvinogadzirisa.

Maintenance uye Kuongororwa kweEEBDs

Kuve nechokwadi chekuti EEBD yakagadzirira kushandiswa munguva yekukurumidzira, kugadzirisa nguva dzose uye kuongororwa kwakakosha. Mamwe emabasa akakosha ekugadzirisa anosanganisira:

• Kuongorora Nguva Dzose: MaEEBD anofanirwa kuongororwa nguva nenguva kutarisa chero zviratidzo zvekupfeka kana kukuvadzwa, kunyanya mumask kumeso, harness, uye cylinder.
• Hydrostatic Testing: Carbon fiber composite silindas inofanirwa kuongororwa hydrostatic nguva nenguva kuti ive nechokwadi chekuti inogona kuramba yakatsiga inodiwa kuchengetedza mweya kana oxygen. Kuyedzwa uku kunosanganisira kuzadza silinda nemvura uye nekuidzvanya kuti itarise kana ichidonha kana kusasimba.
• Kuchengeta Kwakakodzera: MaEEBD anofanirwa kuchengetwa munzvimbo yakachena, yakaoma kure nechiedza chezuva kana tembiricha yakanyanyisa. Kuchengetedza kusina kunaka kunogona kuderedza hupenyu hwechigadzirwa uye kukanganisa kushanda kwayo.

Mhedziso

An Emergency Escape Breathing Device (EEBD) chishandiso chakakosha chekuchengetedza mumaindasitiri umo mhepo ine njodzi inogona kumuka zvisingatarisirwi. Chigadzirwa chacho chinopa kupiwa kwenguva pfupi kwemhepo inofema, zvichiita kuti vashandi vatize nzvimbo dzine ngozi nokukurumidza uye zvakachengeteka. Nekubatanidzwa kwecarbon fiber composite silindas, maEEBD ave akareruka, akasimba, uye akavimbika, achiwedzera kushanda kwawo mumamiriro ezvinhu enjodzi. Kugadzirisa kwakakodzera uye kuongororwa nguva dzose kunovimbisa kuti zvishandiso izvi zvinogara zvakagadzirira kuita basa ravo rinoponesa hupenyu pazvinenge zvichidikanwa.
