Kusankha malo otsekera ndikofunikira pankhani yowonetsetsa kuti malo okhala mafakitale amakhala otetezeka, makamaka madera owopsa. Malo otchinga owopsa amapangidwa kuti ateteze zida zamagetsi ku mpweya wophulika, fumbi ndi zinthu zina zachilengedwe. Bukuli likuthandizani kuyang'ana zovuta pakusankha amalo otetezedwandizoyenera pazosowa zanu zenizeni.
Kumvetsetsa malo oopsa
Musanalowe m'malo osankhidwa, ndikofunikira kumvetsetsa chomwe chili malo owopsa. Maderawa amagawidwa malinga ndi kukhalapo kwa mpweya woyaka, nthunzi kapena fumbi. Machitidwe amagawo nthawi zambiri amakhala:
- Zone 0: Malo omwe mpweya wophulika umakhalapo mosalekeza kapena kwa nthawi yaitali.
- Zone 1: Malo omwe mpweya wophulika ukhoza kuchitika panthawi yogwira ntchito bwino.
- Zone 2: Mpweya wophulika wa gasi sungathe kuchitika nthawi yanthawi zonse, ndipo ngati utero, udzakhalapo kwakanthawi kochepa.
Dera lirilonse limafuna mtundu wina wa mpanda kuti zitsimikizire chitetezo ndikutsatira malamulo.
Mfundo Zofunika Kwambiri Posankha Malo Otsekera Malo Oopsa
1. Kusankha Zinthu
Zomwe zili pamlanduwu ndizofunikira kwambiri kuti zikhale zolimba komanso zotetezeka. Zida zodziwika bwino ndi izi:
- Chitsulo chosapanga dzimbiri: Amapereka kukana kwa dzimbiri kwabwino, koyenera kumadera ovuta.
- Aluminiyamu: Zopepuka komanso zosagwira dzimbiri, koma sizingakhale zoyenera madera onse owopsa.
- Polycarbonate: Amapereka kukana kwabwino ndipo amagwiritsidwa ntchito m'malo ovuta kwambiri.
Kusankha zinthu zoyenera kudzatengera zoopsa zomwe zimapezeka mdera lanu.
2. Ingress Protection (IP) Level
Chiyerekezo cha IP chikuwonetsa kuthekera kwa malo otsekerako kukana fumbi ndi kulowerera kwa madzi. Pamalo owopsa, ma IP apamwamba amafunikira nthawi zambiri. Yang'anani mpanda wokhala ndi IP65 osachepera IP65 kuti muwonetsetse chitetezo ku fumbi ndi ma jeti amadzi otsika.
3. Njira zosaphulika
Pali njira zosiyanasiyana zotetezera kuphulika zomwe zilipo, kuphatikizapo:
- Zosaphulika (Ex d): Zapangidwa kuti zipirire kuphulika mkati mwa mpanda ndikuletsa malawi kuti asatuluke.
- Chitetezo Chokhazikika (Ex e): Onetsetsani kuti zida zidapangidwa kuti zichepetse ngozi yamoto.
- Intrinsic Safety (Ex i): Imachepetsa mphamvu zoyatsira, kuzipangitsa kukhala zoyenera kugwiritsa ntchito Zone 0 ndi Zone 1.
Kumvetsetsa njirazi kukuthandizani kusankha malo otchinga omwe amakwaniritsa zofunikira zamalo owopsa.
4. Kukula ndi Kusintha
Khomalo liyenera kukula kuti likhale ndi zida komanso kuti pakhale mpweya wabwino komanso kutaya kutentha. Ganizirani momwe mungayikitsire ndikuwonetsetsa kuti malo otsekerawo ndi osavuta kuwongolera ndikuwunika.
5. Certification ndi Kutsata
Onetsetsani kuti malo otsekeredwawo akukwaniritsa miyezo ndi ziphaso zoyenera, monga ATEX (ya Europe) kapena NEC (ya United States). Zitsimikizozi zikuwonetsa kuti mpanda wayesedwa ndipo umakwaniritsa zofunikira zachitetezo kumadera owopsa.
6. Mikhalidwe ya chilengedwe
Ganizirani za chilengedwe chomwe kabati idzayikidwe. Zinthu monga kutentha kwambiri, chinyezi, komanso kukhudzana ndi mankhwala zimatha kukhudza kusankha kwa zida zotsekera ndi kapangidwe kake.
Pomaliza
Kusankha zoyeneramalo otetezedwandi lingaliro lofunikira lomwe likukhudza chitetezo ndi kutsata m'mafakitale. Poganizira zinthu monga kusankha kwa zinthu, IP rating, njira yoteteza kuphulika, kukula, ziphaso ndi momwe chilengedwe chikuyendera, mutha kusankha mwanzeru kuti anthu ndi zida zikhale zotetezeka. Onetsetsani kuti mwawonana ndi katswiri ndikutsata malamulo amdera lanu kuti muwonetsetse kuti malo omwe muli owopsa akukwaniritsa zofunikira zonse zachitetezo.
