Momwe mungawerengere matenda a SCBA: Kumvetsetsa nthawi yogwira ntchito ya carbon

Pulogalamu Yodzipuma Yokha (SCBA) silindaA ndi ofunikira kwambiri popereka mpweya wopumira kwa ozimitsa moto, ogwira ntchito apulumutsi, ndi ogwira ntchito zina zowopsa. Kudziwa nthawi yayitali bwanjiSco sinderTidzamaliza ntchito ndiyofunikira pakukonzekera ndikukonzekera chitetezo. Kutalika kwa silinda kumatengera kuchuluka kwake, kukakamizidwa, ndi kupuma kwa wogwiritsa ntchito. Nkhaniyi ikukuyendetsani momwe mungawerengere kungathekeSco sinder, pogwiritsa ntchito njira yosavuta, mwachidwi kuCarbon Trylinder Corlinders, yomwe imagwiritsidwa ntchito kwambiri chifukwa cha zopepuka ndi mphamvu zawo.

Sco sinderZoyambira: kuchuluka ndi kukakamizidwa

Sco sinderS OGULITSIRA MALO OGULITSIRA MALO OGWIRITSIRA NTCHITO YOPHUNZITSIRA, imayesedwa mu mipiringidzo kapena mapaundi pamtunda umodzi (PSI). Kuchuluka kwa mpweya mkati mwa silinda nthawi zambiri kumafotokozedwa mu malita. Zinthu ziwiri zazikulu zomwe zimatsimikizira kuchuluka kwa mpweya womwe ukupezeka ndi:

• Voliyumu ya Cylinder: Uwu ndiye kukula kwamkati kwa silinda, nthawi zambiri kumafotokozedwa mu malita (mwachitsanzo, 6.8-lita kapena 9-lita).
• Kukakamiza kwa Cylinder: Kupanikizika komwe mpweya umasungidwa, makamaka pakati pa 200 ndi 300 barSco sinders.

Carbon Trylinder CorlinderS ndizodziwika mu scba kachitidwe ka SCBA chifukwa amapereka mphamvu yayitali (mpaka 300 bar) pomwe mukukhala opepuka kwambiri kuposa zingwe zachitsulo kapena zitsulo. Izi zimawapangitsa kukhala abwino kwa zochitika zomwe ogwiritsa ntchito amafunikira kuyenda mwachangu kapena kwa nthawi yayitali.

Kutalika kwaSco sinderItha kuwerengeredwa pogwiritsa ntchito njira yotsatirayi:

• "40" mu fomulayi imayimira kuchuluka kwa munthu wopumira. Muyezo uwu umatha kusiyanasiyana kutengera momwe wogwiritsa ntchitoyo amagwirira ntchito, koma malita 40 pa mphindi (L / min) ndi chithunzi chokhazikika.
• "-10" kumapeto kwa fomulayo ndi malire, kuonetsetsa wosuta kumakhala ndi nthawi yotuluka m'malo owopsa mpweya usanathe.

KUSINTHA:

1. Kupumira

Hing kukula kwa 40 l / min, yomwe imagwirizana ndi ntchito yolimbitsa thupi. M'malo mwake, kupumira kumatha kusintha malinga ndi zomwe wogwiritsa ntchito:

• Ntchito zochepa: Ngati wogwiritsa ntchitoyo apumula kapena kugwira ntchito yopepuka, nthawi yopuma ikhoza kukhala yotsika, pafupifupi 20-30 l / min, yomwe ingatalimize nthawi yayitali.
• Ntchito yayikulu: Pakuchita zolimbitsa thupi, monga kumenyera moto kapena kupulumutsa anthu, mitengo yopumira imatha kuwonjezereka mpaka 50-60 l / min kapena kupitirira, kuchepetsa nthawi ya cylinder.

2. Kukakamiza kwa Cylinder

• Kulemera: Carbon vaniveninderS amapepuka kwambiri kuposa chitsulo, kuwapangitsa kukhala osavuta kunyamula ndikuchepetsa kutopa kwa wogwiritsa ntchito nthawi yayitali.
• Kupanikizika Kwambiri: Amatha kudzazidwa kuzovuta mpaka 300 bar, kupereka mpweya wambiri popanda kukula kukula kwa silinda.
• KulimbaMakina ophatikizika a carbon ndi amphamvu kwambiri, amatha kupirira zovuta zambiri mukamakhudzidwa ndi zotsatira za chilengedwe.
