Tawg-Proof Hluav Taws Xob Kev Soj Ntsuam thiab Kuaj Cov Ntsiab Lus

Soj ntsuam cov khoom hluav taws xob, Nws yog ib qho tseem ceeb heev uas yuav tau xyuas cov nram qab no:

1. Zov me nyuam ntawm cov khoom uas explosive tej chaw.

2. Tsim nyog tau txais kev pab ntawm cov khoom.

3. Accuracy ntawm cov khoom hluav taws xob cov pab pawg neeg cov pab pawg neeg classification.

4. Correctness of hluav taws xob thiab wiring labels.

5. Validity ntawm cov ntawv lo rau hluav taws xob thiab wiring.

6. Raws li txoj cai enclosures, pob tshab, hlau ntsaws, los yog adhesives uas yuav tsum tau muaj.

7. Tej pom, tsis pom cai.

8. Kom zoo thiab ruaj ntseg fastening ntawm bolts, cable nkag mechanisms (seb ncaj qha los yog indirect), thiab blanking phaj.

Ntawv Ceeb Toom: Rau d thiab e hom li, Transparent components ua tempered iav yuav tsum tsis tau hloov arbitrarily. Tsuas yog thawj qhov chaw yuav tsum siv tau raws li lub zog yuav tsum tau ua kom muaj ntau yam li thiab cov sealing yuav tsum tau ua kom muaj e hom li ntau yam.

9. Cleanliness thiab ntseeg txog explosion-proof chaw thiab linings (d).

10. Kis loj rau explosion-proof qhov chaw ntxiv nyob rau hauv permissible txwv (d).

11. Correctness ntawm luminaire teeb qhov chaw nyob fais fab tuag, qauv, thiab nruab nrab txoj hauj lwm.

Ntawv Ceeb Toom: Luminaires nrog rau tib lub hwj huam tab sis txawv qauv txawv hauv tso zis tso zis thiab components, thiab yuav tsum tsis txhob muab hloov tsis tau. Piv txwv, LED luminaires muaj high-up kub, Ua bulbs nyob rau lwm hom luminaires.

12. Ruaj ntseg ntawm hluav taws xob sib txuas.

13. Mob ntawm tus enclosure lining.

14. Integrity of sealed thiab airtight circuit breakers.

15. Ua kom muaj kev ua kom ib tloog zoo ntawm txoj kev txwv tsis pub ua pa enclosure.

Ntawv Ceeb Toom: Txoj cai IP yuav tsum tau stringent, Yuav tsum tau lub siab ntawm tus ntaus ntawv nyob ruaj khov nyob ruaj khov nyob rau hauv nqus tsev nqus tsev.

16. Txaus qhov chaw ntawm lub kiv cua motor thiab cov enclosure los yog npog.

Ntawv Ceeb Toom: Tus spacing yuav tsum tshaj 1% ntawm tus impeller diameter tab sis tsawg tshaj li los yog sib npaug zos rau 5mm.

17. Adherence ntawm kev ua pa thiab draining li rau cov qauv kawm.
Ntawv Ceeb Toom: Breathers thiab drainers feem ntau specialized components hauv lub tawg-pov thawj chamber ntawm “d” roj detectors. Cov li no tuaj nyob rau hauv ntau yam lug, xws li plua plav metallurgy, txheej hlau mesh, kuav los tiag zaj duab xis, thiab labyrinthine designs.

18. Certification of safety barrier units, relays, thiab lwm yam txwv zog li explosion-proof, nrog rau cov plahaum nruab nrab thiab hauv pem teb (Kuv).
Ntawv Ceeb Toom: Txawm tias tawg-pov thawj barriers feem ntau siv nyob rau tej cheeb tsam zoo, lawv yuav tsum muaj daim ntawv pov thawj zov me nyuam.

19. Installation ntawm intrinsic kev ruaj ntseg li ib documentation specifications (tsuas yog kom tas cov khoom) (Kuv).

20. Cleanliness thiab hla kev puas tsuaj rau intrinsic kev ruaj ntseg ntaus circuit Boards (Kuv).

21. Hla defects xws li cracking hauv encapsulated plhaub khoom (m).

Ntawv Ceeb Toom: Cov cim hauv niam txiv thaum kawg ntawm txhua cov khoom uas muaj cov khoom denote lub specific tawg-profo uas cov khoom siv. Cov khoom uas tsis muaj niam txiv tsis tau muaj feem xyuam rau tag nrho explosion-proof hom.
