An Emergency Escape Breathing Device (EEBD) ndi chida chofunikira kwambiri chachitetezo chopangidwa kuti chizigwiritsidwa ntchito m'malo omwe mlengalenga wakhala wowopsa, zomwe zikuyika pachiwopsezo chamoyo kapena thanzi. Zipangizozi zimagwiritsidwa ntchito kwambiri pazochitika pamene mpweya wapoizoni umatuluka mwadzidzidzi, utsi, kapena kusowa kwa okosijeni, zomwe zimapatsa mwiniwake mpweya wokwanira wopuma kuti athawe bwinobwino malo owopsa.
Ma EEBD amapezeka m'mafakitale osiyanasiyana, kuphatikiza kutumiza, migodi, kupanga, ndi ntchito zadzidzidzi, ndipo adapangidwa kuti azipereka chitetezo kwakanthawi kochepa kwa anthu omwe akuthawa malo owopsa m'malo mogwiritsa ntchito nthawi yayitali. Ngakhale kuti sizinapangidwe zozimitsa moto kapena ntchito zopulumutsa, ma EEBD ndi chida chofunikira chotetezera chomwe chingalepheretse kutsekemera kapena poizoni pamene sekondi iliyonse ikuwerengera. Chigawo chachikulu cha ma EEBD amakono ndicarbon fiber composite silinda, yomwe imathandizira kwambiri kuti zidazi zikhale zopepuka, zolimba, komanso zodalirika pakagwa ngozi.
Momwe EEBD Imagwirira Ntchito
EEBD ndi chipangizo chopumira chomwe chimapatsa wogwiritsa ntchito mpweya wopumira kapena mpweya kwa nthawi yochepa, makamaka pakati pa mphindi 5 mpaka 15, kutengera chitsanzo. Chipangizocho ndi chosavuta kugwiritsa ntchito, ngakhale pansi pa kupsinjika, ndipo nthawi zambiri chimayendetsedwa ndi kukoka tabu kapena kutsegula chidebecho. Akangoyatsidwa, mpweya kapena mpweya umayamba kuyenda kwa wogwiritsa ntchito, mwina kudzera pa chigoba chakumaso kapena cholumikizira pakamwa ndi pamphuno, ndikupanga chisindikizo chomwe chimawateteza kuti asapume mpweya woipa kapena mpweya wopanda mpweya.
Zithunzi za EEBD
Zigawo zoyambira za EEBD ndi:
- Cylinder kupuma: Silinda iyi imasunga mpweya wopanikiza kapena okosijeni womwe wogwiritsa ntchito amapuma panthawi yothawa. Ma EEBD amakono akugwiritsa ntchito kwambiri carbon fiber composite silindachifukwa cha kupepuka kwawo komanso mphamvu zawo.
- Pressure Regulator: Woyang'anira amawongolera kutuluka kwa mpweya kapena mpweya kuchokera mu silinda, kuonetsetsa kuti wogwiritsa ntchito amalandira mpweya wabwino wopuma.
- Nkhope Mask kapena Hood: Chigoba kapena hood imaphimba nkhope ya wogwiritsa ntchito, kupereka chisindikizo chomwe chimateteza mpweya woopsa pamene chimawalola kupuma mumlengalenga kapena mpweya woperekedwa ndi EEBD.
- Kumangirira kapena Lamba: Izi zimateteza chipangizo kwa wogwiritsa ntchito, kuwalola kuti azisuntha momasuka atavala EEBD.
- Alamu System: Ma EEBD ena ali ndi alamu yomwe imamveka pamene mpweya ukuyenda pang'onopang'ono, zomwe zimapangitsa kuti wogwiritsa ntchitoyo afulumire kuthawa.
Carbon Fiber Composite Cylinders mu EEBDs
Chimodzi mwazinthu zofunika kwambiri za EEBD ndi silinda yopumira, ndipo zinthu zomwe zimagwiritsidwa ntchito pa silindayi zimagwira ntchito yofunika kwambiri pakugwiritsa ntchito chipangizocho. M'ma EEBD ambiri amakono,carbon fiber composite silindas amagwiritsidwa ntchito chifukwa chapamwamba kwambiri poyerekeza ndi zipangizo zamakono monga chitsulo kapena aluminiyamu.
Mapangidwe Opepuka
Chimodzi mwazabwino kwambiri zacarbon fiber composite silindas ndi mapangidwe awo opepuka. Pazochitika zadzidzidzi, sekondi iliyonse imawerengera, ndipo EEBD yopepuka imalola wogwiritsa ntchito kuyenda mwachangu komanso mosavuta. Ma composites a carbon fiber ndi opepuka kwambiri kuposa chitsulo ndi aluminiyamu pomwe amakhalabe amphamvu mokwanira kuti azikhala ndi mpweya woponderezedwa kapena okosijeni pakapanikizika kwambiri. Kuchepetsa kulemera kumeneku kumathandiza wogwiritsa ntchito kupewa kutopa, zomwe zimapangitsa kuti zikhale zosavuta kunyamula chipangizochi panthawi yothawa.
High Durability ndi Mphamvu
Silinda ya carbon fiber composites siwopepuka komanso amphamvu kwambiri komanso olimba. Amatha kupirira kupsinjika kwakukulu kofunikira kuti asungire mpweya wokwanira kuti athawe bwino, ndipo amalimbana ndi kuwonongeka chifukwa cha kukhudzidwa, dzimbiri, ndi kuvala. Kukhalitsa kumeneku ndikofunikira pakachitika ngozi pomwe chipangizocho chingagwire ntchito movutikira, kutentha kwambiri, kapena kukhudzidwa ndi mankhwala oopsa. Mphamvu ya mpweya wa carbon fiber imalola kuti silinda ikhale yosasunthika komanso yogwira ntchito, kuonetsetsa kuti wogwiritsa ntchito ali ndi mpweya wodalirika pamene akuufuna kwambiri.
Kuchuluka kwa Mphamvu
Ubwino wina wacarbon fiber composite silindas ndi kuthekera kwawo kosunga mpweya wambiri kapena okosijeni mu phukusi laling'ono, lopepuka. Kuchulukiraku kumapangitsa kuti pakhale nthawi yayitali yothawira, kupatsa ogwiritsa ntchito mphindi zowonjezera za mpweya wopumira kuti atuluke pamalo owopsa. Mwachitsanzo, acarbon fiber composite silindaimatha kupereka mpweya wofanana ndi silinda yachitsulo koma yocheperako komanso kulemera kwake, kupangitsa kuti ikhale yothandiza kwambiri kuti igwiritsidwe ntchito m'malo ochepa kapena kwa ogwiritsa ntchito omwe akufunika kuyenda mwachangu.
Kugwiritsa ntchito ma EEBDs
Ma EEBD amagwiritsidwa ntchito m'mafakitale omwe ogwira ntchito amatha kukhala ndi mlengalenga wowopsa. Izi zikuphatikizapo:
- Maritime Industry: Pa zombo, EEBD nthawi zambiri imafunika ngati gawo la zida zotetezera. Pakachitika moto kapena gasi kutayikira, ogwira nawo ntchito atha kugwiritsa ntchito EEBD kuthawa zipinda zamainjini kapena malo ena otsekeka pomwe mpweya umakhala wowopsa.
- Migodi: Migodi imadziwika ndi mpweya woopsa komanso malo omwe amakhala ndi mpweya wa oxygen. EEBD imapatsa ogwira ntchito kumigodi njira zopulumukira mwachangu komanso zosunthika ngati mpweya ukhala wosatetezeka kupuma.
- Industrial Plants: Mafakitole ndi zomera zomwe zimagwira ntchito ndi mankhwala owopsa kapena njira zowononga zingafunike ogwira ntchito kuti agwiritse ntchito ma EEBD ngati mpweya wotuluka kapena kuphulika kwachitika, zomwe zimapangitsa kuti pakhale mpweya woopsa.
- Ndege: Ndege zina zimanyamula ma EEBD kuti ateteze ogwira nawo ntchito ndi okwera ku mpweya wa utsi kapena kusowa kwa okosijeni pakagwa mwadzidzidzi.
- Makampani a Mafuta ndi Gasi: Ogwira ntchito m'malo oyenga mafuta kapena pobowola m'mphepete mwa nyanja nthawi zambiri amadalira ma EEBD ngati gawo la zida zawo zodzitetezera kuti athawe kutayikira kwa gasi kapena moto.
EEBD vs. SCBA
Ndikofunika kumvetsetsa kusiyana pakati pa EEBD ndi Self-Contained Breathing Apparatus (SCBA). Ngakhale zida zonse ziwiri zimapereka mpweya wopumira mumlengalenga wowopsa, zidapangidwira zolinga zosiyanasiyana:
- EEBD: Ntchito yayikulu ya EEBD ndikupereka mpweya kwakanthawi kochepa pofuna kuthawa. Sichidapangidwa kuti chizigwiritsidwa ntchito kwa nthawi yayitali ndipo chimagwiritsidwa ntchito pochotsa anthu mwachangu kumadera akupha kapena opanda mpweya. Ma EEBD nthawi zambiri amakhala ang'onoang'ono, opepuka, komanso osavuta kugwiritsa ntchito kuposa ma SCBA.
- SCBA: SCBA, kumbali ina, imagwiritsidwa ntchito kwa nthawi yayitali, monga kuzimitsa moto kapena ntchito zopulumutsa. Makina a SCBA amapereka mpweya wochuluka kwambiri, womwe nthawi zambiri umakhala mpaka ola limodzi, ndipo amapangidwa kuti azigwiritsidwa ntchito pakachitika zoopsa. Ma SCBA nthawi zambiri amakhala okulirapo komanso ovuta kuposa ma EEBD ndipo amaphatikiza zinthu zapamwamba monga ma geji othamanga, ma alarm, ndi zowongolera zosinthika.
Kusamalira ndi Kuyang'anira ma EEBD
Kuwonetsetsa kuti EEBD ndiyokonzeka kugwiritsidwa ntchito pakagwa mwadzidzidzi, kukonza nthawi zonse ndikuwunika ndikofunikira. Zina mwa ntchito zazikulu zowongolera ndi izi:
- Kuyendera Nthawi Zonse: Ma EEBD ayenera kuyang'aniridwa nthawi ndi nthawi kuti awone ngati pali zizindikiro zilizonse zowonongeka kapena zowonongeka, makamaka pa chigoba cha kumaso, zitsulo, ndi silinda.
- Kuyeza kwa Hydrostatic: Silinda ya carbon fiber composites ayenera kuyezetsa hydrostatic pafupipafupi kuti atsimikizire kuti atha kupirira kupsinjika kwakukulu komwe kumafunikira kuti asunge mpweya kapena mpweya. Kuyezetsa kumeneku kumaphatikizapo kudzaza madzi mu silinda ndi kukanikiza kuti awone ngati akutuluka kapena kufooka.
- Kusungirako Koyenera: Ma EEBD akuyenera kusungidwa pamalo oyera, owuma kutali ndi dzuwa kapena kutentha kwambiri. Kusungirako kosayenera kungachepetse moyo wa chipangizocho ndikusokoneza ntchito yake.
Mapeto
An Emergency Escape Breathing Device (EEBD) ndi chida chofunikira chachitetezo m'mafakitale pomwe mlengalenga wowopsa ukhoza kuwuka mosayembekezereka. Chipangizochi chimapereka mpweya wopumira kwakanthawi kochepa, zomwe zimalola ogwira ntchito kuthawa malo owopsa mwachangu komanso mosamala. Ndi kuphatikiza kwacarbon fiber composite silindas, ma EEBD akhala opepuka, okhazikika, komanso odalirika, kupititsa patsogolo mphamvu zawo pakagwa mwadzidzidzi. Kusamalira moyenera ndi kuyang'anitsitsa nthawi zonse kumatsimikizira kuti zipangizozi zimakhala zokonzeka nthawi zonse kugwira ntchito yopulumutsa moyo ikafunika.
