Mfundo ndi Ubwino ndi Kuipa kwa Mtundu wa Flameproof, Intrinsically Safe, Ndipo Mitundu Yabwino Yopanikizika

Mtundu wa Flameproof:

Mfundo Yoteteza Kuphulika:

Mfundo yoteteza moto imakhudzanso pogwiritsa ntchito chotchinga chosaphulika chomwe chimalimbana ndi kuphulika kwa mkati, kuletsa kusakaniza kwamkati kufalikira kumadera ozungulira. Mipata yonse yosayaka moto ndi yocheperapo kusiyana ndi kusiyana kwakukulu koyeserera kotetezeka kwa gasi woyaka omwe akufunsidwa (pamikhalidwe yoyezetsa, kusiyana kwakukulu pakati pa zigawo ziwiri za olowa, zomwe sizingayatse chisakanizo chophulika chakunja pamene chosavuta kuyatsa ndende yosakanikirana yophulika mkati mwa casing iyaka.). Ngati mpweya woyaka umalowa m'bokosi ndikuyaka, kuchititsa kuphulika, moto wophulika uli mkati mwa bokosilo, osatha kuyatsa zosakaniza zophulika zakunja, motero kuonetsetsa chitetezo cha malo ozungulira.

Ubwino wake:

Zosayaka moto zotchingira zimagwiritsidwa ntchito kwambiri ndi mamangidwe osavuta.

Zoipa:

Iwo ndi ochuluka ndipo ali ndi zofunikira zenizeni za zingwe, zolumikizana, njira, zitsulo, ndi manja (m'mimba mwake wa mphete yosindikizira mphira mkati mwa mkonoyo uyenera kufanana ndi m'mimba mwake wakunja kwa mkonowo ndikutetezedwa ndi nati woponderezedwa.; ngati zitsulo zazitsulo zimagwiritsidwa ntchito, asindikizidwe ndi kulongedza katundu monga momwe ananenera; ngati dzanja lopanda chingwe likugwiritsidwa ntchito, cholowetsacho chiyenera kusindikizidwa molingana ndi zofunikira zoyenera). Sizololedwa kutsegula posungira pamene muli ndi mphamvu m'malo owopsa; kutsegula chosungira kumafuna zida zapadera, komanso kuyika ndi kukonza zolakwika kungayambitse zinthu zoopsa. Zotsekera zotchingira moto siziloledwa ku Zone 0 ndipo nthawi zambiri amagwiritsidwa ntchito ngati injini, kuyatsa, ndi zina.

Intrinsically Safe Type:

Mfundo Yoteteza Kuphulika:

Zotetezeka kwenikweni, kapena “Intrinsic Safety,” amatanthauza mfundo yoteteza kuphulika kumene mphamvu ya zokoka zamagetsi kapena zotulukapo za kutentha zomwe zimapangidwa mkati mwa chipangizo kapena mawaya ake olumikizira owonekera zimangokhala mulingo womwe sungathe kuyatsa. Izi zikutanthauza kuti pansi ntchito yachibadwa kapena zotchulidwa zolakwika zinthu, palibe osankhidwa zophulika osakaniza akhoza kuyatsa. Njira zazikulu zodzitchinjiriza zimaphatikizapo kuchepetsa mphamvu yamagetsi yamagetsi ndi yapano komanso ma capacitance ndi inductance ya dera, ogawidwa mu Type ia (kulola mfundo ziwiri zolakwika) ndi Type ib (kulola vuto limodzi).

Ubwino wake:

Zipangizo sizifuna zingwe zapadera, kupangitsa kuti zikhale zotetezeka kwa ogwira ntchito kusamalira ndi kukonza, ndipo zovundikira zitha kutsegulidwa mukayatsidwa.

Zoipa:

Sikoyenera kuzipangizo zamphamvu kwambiri ndipo nthawi zambiri amagwiritsidwa ntchito pazida zotsika mphamvu pakuyezera, kulamulira, ndi kulankhulana. 'Ib’ type imatha kugwira ntchito mu Zone 0; 'Ib’ type imatha kugwira ntchito mu Zone 1.

Mitundu Yabwino Yopanikizika:

Mfundo Yoteteza Kuphulika:

Mfundo ya kupanikizika kwabwino mitundu ya chitetezo kuphulika kumaphatikizapo kubweretsa mpweya wabwino kapena mpweya wa inert pakapanikizika kwina m'malo otsekeredwa, kuletsa mpweya woyaka kulowa ndi, motero, kuletsa magwero oyatsira kuti asakumane ndi mpweya wophulika, potero kupewa kuphulika. Njira zazikulu zopangira zida zamagetsi zopanikizidwa ndikusunga mpweya woteteza (mpweya wabwino kapena gasi wopanda pake) kupsyinjika mkati mwa casing kuposa 50 Pascal. Zofunikira pazida zamagetsi zopanikizika zimaphatikizapo: bwalo, mapaipi, ndipo kugwirizana kwawo kuyenera kukhazikika 1.5 nthawi zambiri zokakamiza zabwino ndi ma doko onse otayira otsekedwa pansi pamikhalidwe yabwinobwino yogwirira ntchito monga momwe wopanga amanenera, ndi kuthamanga kochepa kwa 200Pa. Mpweya woteteza mpweya uyenera kukhala pamalo osawopsa, wopanda zowononga media; utsi uyenera kukhala pamalo osawopsa, kapena spark ndi tinthu kudzipatula baffles ayenera kuganiziridwa; zida zomwe zimayang'anira kuthamanga kwa mpweya ndi kayendedwe ka mpweya ziyenera kukhazikitsidwa molingana ndi dzina lazinthu kapena zolemba zamanja.

Ubwino wake:

Itha kugwiritsidwa ntchito ngati njira zina sizikugwira ntchito.

Zoipa:

Kuyika ndi kukonza ndizovuta komanso zodula; ngati zida kukumana kuyaka zosakaniza, njira zina zotetezera ziyenera kuchitidwa; palibe ntchito yachivundikiro yamphamvu yomwe imaloledwa. Amagwiritsidwa ntchito pama mota akulu, thiransifoma, ndi masiwichi amphamvu kwambiri. Kagwiritsidwe ntchito kololedwa: Zida zokhala ndi mphamvu zodzipangira zokha zitha kugwiritsidwa ntchito ku Zone 1; zida zokhala ndi ma alarm acoustic-optic zitha kugwiritsidwa ntchito ku Zone 2.

Panopa, zinthu za kampani yathu zomwe sizingaphulike makamaka zimakhala zosapsa, otetezeka mkati, ndi mitundu yopanikizidwa. Kaya njira, mfundo yofunika ndikuletsa zida zamagetsi kuti zisakhale gwero loyatsira. Njira yofunika kwambiri yopewera kuphulika ndiyo kuonetsetsa kuti zinthu zitatu zoyaka moto—mafuta, oxidizer, ndi gwero loyatsira - sizimakhala nthawi ndi malo. Pambuyo poganizira za ntchito zosiyanasiyana, mtundu woyenera kwambiri wamagetsi oletsa kuphulika uyenera kusankhidwa, poganizira za mtengo wake komanso kusavuta kukonza, kuchepetsa chiwopsezo cha ngozi zapamalo.
