Kodi Chingwe Chotetezedwa Mwachilengedwe cha SWA Armoured ndi Chiyani?
- Kodi Chingwe Chotetezedwa Mwachilengedwe cha SWA Armoured ndi Chiyani?
AnChingwe chotetezedwa bwino cha SWA (Steel Wire Armour)ndi chingwe chapadera cha malo oopsa chomwe chimaphatikiza zinthu ziwiri zofunika kwambiri:
| Mbali | Cholinga | Phindu |
| Chitetezo cha Mkati (IS) | Kuchepa kwa mphamvu — sikungayambitse kuyaka | Zotetezeka kumadera oopsa a Zone 0/1/2 (mpweya, nthunzi, fumbi) |
| Zida Zachitsulo Zachitsulo (SWA) | Chitetezo cha makina — kuphwanya, kukhudza, mbewa, kukoka | Imapulumuka kuikidwa m'manda mwachindunji, malo ovuta a mafakitale, komanso kupsinjika kwa makina |
Kuphatikiza:Chingwe cha IS SWA chimakupatsani mwayi woyendetsa ma circuits otetezeka mkati mwa malo ovuta kwambiri amakina - malo oikamo maliro mwachindunji, ma trey a ma cable okhala ndi magalimoto ambiri, malo okhala makoswe ambiri, komanso malo oyika panja - pamene mukutsatira malamulo onse a malo oopsa.
(Gawo lodutsa chingwe chotetezedwa bwino cha SWA choteteza makina)
Pa Dingzun Cable,Timapanga zingwe zotetezedwa za SWA zokhala ndi sheathing yabuluu ya LSZH, zida zoteteza zitsulo zomangira, komanso ma rating ovomerezeka a Ex-ia/Ex-ib a zida zoopsa.
- Kodi N’chiyani Chimasiyanitsa SWA? Zida Zachitsulo Zachitsulo Zafotokozedwa
SWA (Steel Wire Armour) ndi waya wachitsulo wopangidwa ndi galvanized womwe umayikidwa pakati pa jekete lamkati ndi chidebe chakunja cha chingwe.
Gome 1: Zida za SWA — Zoteteza Makina
| Mtundu wa Chitetezo | Kutha kwa SWA | Njira Yoyesera | Mtengo Wamba |
| Kukaniza Kukaniza | Imapirira kupsinjika kwakukulu ndi kukhudzidwa | EN 60811-508 | >4,000 N/10cm(4,000+ Newtons kutalika kuposa 10cm) |
| Chitetezo cha Makoswe / Nsikidzi | Mawaya achitsulo amaletsa mano a makoswe kulowa | Muyezo wamakampani | Mawaya achitsulo ndi olimba kuposa mano a makoswe; amaletsa kuwonongeka kwa chingwe |
| Kulimba kwamakokedwe | Imapirira kukoka panthawi yoyika | EN 60811-501 | >2,000 kg(zimasiyana malinga ndi kukula kwa kondakitala ndi makulidwe a zida) |
| Kukana Kukhudzidwa | Anapulumuka zida zogwa, zinthu zogwetsedwa, ndi anthu oyenda pansi | EN 60811-509 | >5 Joule(waya wachitsulo umayamwa ndikugawa mphamvu yamagetsi) |
| Kukana Kumva Kuwawa | Imalimbana ndi kusweka kwa miyala, mathireyi, ndi konkriti | Zatsimikiziridwa m'munda | Waya wachitsulo umapereka malo okhazikika ovalira asanafike pa kutentha kwa dzuwa |
Kupanga Chingwe Chotetezedwa ndi Zida cha SWA (kuchokera mkati mpaka kunja):
| Gawo | Zinthu Zofunika | Ntchito |
| 1. Wotsogolera | Mkuwa wopangidwa ndi zitini | Kutumiza chizindikiro |
| 2. Kuteteza kutentha | PE kapena XLPE (Cc yotsika) | Kuteteza magetsi; mphamvu yochepa ya IS |
| 3. Ma Pair Opotoka | Kuzindikiritsa kwabuluu/kuda | Kukana phokoso |
| 4. Kuteteza (ngati mukufuna) | Lukidwe la mkuwa lopangidwa ndi chitini (≥85%) | Chitetezo cha EMI |
| 5. Chigoba Chamkati | LSZH kapena PVC | Zofunda zotetezera |
| 6. SWA Armour | Waya wachitsulo wopangidwa ndi galvanized | Chitetezo cha makina |
| 7. Chigoba Chakunja | LSZH yabuluu yowala | Kuzindikira IS; kuteteza chilengedwe |
Pa Dingzun Cable,Zingwe zathu zotetezedwa ndi SWA zimagwiritsa ntchito waya wachitsulo wopangidwa ndi galvanized wokhala ndi kutalika kofanana komanso kuphimba kofanana, kuonetsetsa kuti chingwe chonsecho chili ndi chitetezo chofanana.
- Kodi IS ndi SWA Zimagwirizana? Inde — Ndi Kapangidwe Koyenera
Inde, chitetezo chamkati ndi zida zachitsulo zimagwirizana mokwanira - bola chingwecho chapangidwa ndikuyikidwa bwino.
Nkhawa:Zida zankhondo za SWA zimapangidwa ndi chitsulo, chomwe chimagwiritsidwa ntchito poyendetsa zinthu. Kodi chingasunge kapena kutulutsa mphamvu zoopsa zomwe zingasokoneze chitetezo chamkati?
Yankho:Ayi — ikapangidwa bwino komanso pansi, zida za SWA sizikhudza chiwerengero cha IS.
(Chingwe chotetezedwa bwino cha SWA chikuyikidwa)
Gome 2: Kugwirizana kwa IS + SWA — Zofunikira ndi Kutsatira Malamulo
| Chofunikira | Kufotokozera | Chifukwa Chake Ndi Chofunika |
| Zida Sizili mbali ya IS circuit | Chida choteteza waya chachitsulo chimachotsedwa kwa oyendetsa a IS ndi chidebe chamkati | Zida sizili ndi mphamvu ya IS; sizingasunge kapena kutulutsa mphamvu yoyatsira |
| Kukhazikika koyenera (mfundo imodzi) | Zida zankhondo zakhazikika pansi pambali imodzi yokha(malo otetezeka nthawi zambiri) | Zimaletsa kuzungulira kwa nthaka; zimaonetsetsa kuti zida sizinyamula magetsi osochera |
| Chidebe chakunja chimakhalabe chabuluu wowala | Chidebe chakunja cha RAL 5015 LSZH pamwamba pa zida | Amasunga chizindikiritso cha IS motsatira IEC 60079-14 |
| Ma Cc/Lc olembedwa | Zida zimakhudza mphamvu ya chingwe (Cc) — ziyenera kulembedwa | Kutsimikizira kwa bungwe kumafuna mfundo zolondola za Cc kuphatikizapo zotsatira za chitetezo |
| Chitsimikizo cha IS chovomerezeka | Chingwe chimanyamula chizindikiro cha Ex-ia kapena Ex-ib | Kutsatira malamulo a IEC 60079-11 kwa munthu wina kapena kolembedwa |
Chitsanzo cha Makampani:Monga momwe zasonyezedwera mu mafotokozedwe a chingwe chofalitsidwa, *"RE-2X(st)H SWAH – zingwe zolumikizira zida za IS"* zimaphatikiza zingwe zabuluu ndi zida zotetezera za SWA, zomwe zimakwaniritsa zofunikira za EN 50288-7 (muyezo wa zingwe zolumikizira zida) ndi IS. Zingwe izi zimagwiritsidwa ntchito kwambiri m'malo owopsa aku Europe.
Pa Dingzun Cable,Zingwe zathu za IS SWA zapangidwa ndi magawo a Cc ndi Lc olembedwa omwe amaphatikizapo zotsatira za zida za waya wachitsulo — kuonetsetsa kuti mawerengedwe olondola azinthu za dongosolo lanu la IS.
