Choosing the Right Explosion-proof Equipment for Your Company’s Operations

90% o nā ulia pahū i hana ʻia e ke koho pono ʻole ʻana i nā lako!

He mea weliweli nā pahū ʻoihana—akā, hiki ke pale ʻia ka hapa nui. Inā ʻoe e hana ana i ka ʻaila a me ke kinoea, ka hana kemika, a i ʻole kekahi ʻoihana weliweli, nou kēia alakaʻi. E aʻo pehea e koho ai i nā mea hana pale pahū kūpono e kūlike me nā kūlana honua a pale akuʻo kāu ʻeluanā kānaka a me nā waiwai.

1. Ke hoʻomaopopo neikaNā Māka Pale Pahū

kēlā me kēiahōʻoia ʻiaLoaʻa i ka hāmeʻa nā hōʻailona koʻikoʻi, e like me:
Kinoea: Ex db ⅡC T6 Gb / Lepo: Ex tb ⅢC T85℃ Db

ʻO kēia codeʻinos:

Ex db= Palekana pale ahi (no nā wahi kinoea)

ʻElua C= Kiʻekiʻe loahui kinoea pilikia(haikokena, ʻasetilena)

T6= Ka mahana kiʻekiʻe loa o ka ʻilikai ≤ 85°C (ka helu palekana loa)

ⅢC= Kiʻekiʻe loahui lepo pilikia(nā metala alakaʻi e like me ka alumini/magnesium)

ʻO kā mākounā mea hoʻoikaika damper pale pahūe hoʻokō i kēia mau kūlana, e hōʻoiaʻiʻo ana i ka palekana loa.

2. Nā ʻAno Palekana Pahū (ʻO wai ka mea āu e pono ai?)

ʻAno	Noi	Hoʻohana Maʻamau
Pale ahi (Ex db)	ʻĀpana 1/2 (mana kiʻekiʻe)	Nā motika, nā mea hoʻoikaika, nā lako kaumaha
Palekana Kūloko (Ex i)	ʻĀpana 0 (mana haʻahaʻa wale nō)	Nā ʻāpana hoʻomalu, nā mea ʻike
Hoʻonui Palekana (Ex e)	ʻAʻole e ʻā ana, mana waena	Nā mea ʻike passive, nā pahu hui

※ Hoʻohana kā mākou huahana i ka Flameproof (Ex db), kūpono no nā noi ʻoihana mana kiʻekiʻema ka ʻĀpana 1/2.

3. E ʻIke i Kou Kaiapuni: Nā Pōʻino Kinoea a me ka Lepo

Nā Kaiapuni Pahū Kinoea (Papa II)

ʻElua A(Haʻahaʻa ka pilikia) - Propane, butane

ʻElua B(Ka pilikia waena) - Ethylene, nā kinoea ʻoihana

ʻElua C(ʻO ka pilikia kiʻekiʻe loa) - Hydrogen, acetylene

Nā Kaiapuni Pahū Lepo (Papa III)

ⅢA– Nā olonā lapalapa (pulupulu, lāʻau)

ⅢB– Lepo ʻaʻole e alakaʻi (palaoa, lanahu)

ⅢC– Lepo alakaʻi (alumini, magnesium)

※ Uhi kā mākou lako i ka ⅡB, ⅡC (kinoea) a me ⅢC (lepo)—nā kūlana weliweli loa.

4. He mea nui nā helu mahana—ʻO T6 ka mea palekana loa

Papa	Ka Mahana ʻIli Loa.	Nā Hiʻohiʻona Pōpilikia Kiʻekiʻe
T3	200°C	Nā hale hana kemika waiwai i ka hydrogen
T4	135°C	Nā waihona ʻaila, ka mālama ʻana i ka ether
T5	100°C	Nā wahi lepo haʻahaʻa-ā
T6	85°C	Nā keʻena hoʻokolohua, nā hui hydrogen-ea

※ ʻO kā mākou mau mea hoʻopaʻa pahū he T6-rated—ʻo ke kiʻekiʻe loaka helu palekana no ka mahana o ka ʻili.

5. Ka Hoʻokaʻawale ʻĀina Pōʻino:E koho i nā mea hana kūpono no ka hoʻonohonoho ʻana

KinoeaNā ʻĀpana

ʻĀpana 0– Paʻa mauke alo o ke kinoea(e laʻa, i loko o nā pahu wahie)

ʻĀpana 1–Pinepine ke alo o ke kinoea(e laʻa, reactor kemika, ka hana ʻananā wahi)

ʻĀpana 2–I kekahi manawapilikia (e laʻa, ka hoʻouka ʻana i wahowahis, nā wahi mālama)

LepoʻĀpanas

ʻĀpana 20– Nā ao lepo mau (e laʻa, i loko o nā silos)

ʻĀpana 21–Ka ʻike pinepine ʻia ʻana o ka lepo(e laʻa me nā kāʻei hoʻoili)

ʻĀpana 22– Ka ʻike ʻole ʻia o ka lepo (e laʻa, nā liki o ke kānana)

※ Ua hōʻoia ʻia kā mākou huahana no ka ʻĀpana 1/2 (kinoea) a me ka ʻĀpana 21/22 (lepo).

Hopena: E koho i ka pono, e noho palekana

ʻAʻole wale ka pale ʻana i ka pahū e pili ana i ka mālama ʻana—e pili ana ia i ke kuleana. Me:

• Pale ahi Ex dbhoʻolālā,

• Nā palapala hōʻoia noNā wahi IIC/IIIC,

• Palekana wela i helu ʻia ʻo T6, a me

• Hoʻokō meʻO ATEX a me IECEx

Ua hilinaʻi ʻia kā mākou mau actuators pale pahū i nā kūlana ʻino loa o ka honua.

Mai hoʻokuʻu. E hoʻonui i ka palekana i hōʻoia ʻia i kēia lā.

Nā ʻatikala pili

Ua hala nā huahana pahū-pahū a ka hui i ka palapala hōʻoia ATEX o ka EU

Nā Mea Hoʻokō Damper: ʻO ke kikowaena mana kikoʻī o nā ʻōnaehana HVAC, me kahi ʻōlelo paipai no nā huahana Soloon Controls
