Kev tsim khoom
1. FlameProof Lub zog tsim qauv: Lub ntsej muag FlameProof yuav tsum muaj lub zog txaus los tiv thaiv qhov tawg siab uas yuav tsim tawm sab hauv. Lub zog tsim ntawm cov khoom siv yuav tsum tau txiav txim siab los ntawm kev xam los ntawm kev xam raws nws cov khoom thiab lub siab nws yuav tiv taus. For example, the enclosure of Class I, IIA and IIB electrical equipment should be able to withstand a 1.0MPa water pressure test for 12 seconds without damage; Qhov chaw ntawm cov khoom siv hluav taws xob cov cuab yeej siv hluav taws xob yuav tsum muaj peev xwm tiv thaiv tau 1.5mpa dej siab kuaj rau 12 vib nas this yam tsis muaj kev puas tsuaj.
2. Flameproof Standuction Design: Cov kev ntsuas ntawm cov txheej txheem flameproof sib koom ua ke ,, suav nrog cov txheej txheem ntawm lub teb chaws
3. Cov qauv tsim qauv ua tiav: Cov Fasteners yog qhov tseem ceeb los xyuas kom ua tau kev ua haujlwm ntawm cov koob yees duab tawg. Fasteners tsuas yog tso loosened lossis tshem tawm nrog cov cuab yeej; Lub Fastening Screws siv rau cov khoom siv uas muaj cov khoom siv hlau lossis yas, ntev npaum li cov khoom siv nrawm yog qhov tsim nyog rau cov khoom siv.
4. Sealing Tsim: Lub nplhaib sib khi yuav tsum yog ua los ntawm cov kev laus roj hmab, xws li cov roj hmab nyuaj, thiab cov roj hmab ntawm cov khoom siv sealing yuav tsum ua kom muaj qhov tsawg kawg nkaus ntawm cov nplaim taws.
5. Cov qauv hauv av: lub plhaub av ntawm cov khoom siv hluav taws xob yuav tsum tau nruab nrog qhov chaw sib txuam sab nraud, thiab lub thawv hlws ris yuav tsum tau nruab nrog lub davhlau ya nyob sab hauv. Lub davhlau ya nyob twg yuav tsum khij nrog cov cim hauv av "〨". Qhov chaw hauv av yuav tsum yog xeb lossis ua los ntawm cov ntaub ntawv stainless.
6. Qhov kub pab pawg tsim: Qhov ntsuas kub pab pawg ntawm cov koob yees duab kom ntseeg tau tias qhov kev xav tau ntawm cov khoom kub tsis ntau tshaj qhov ntsuas kub ntawm ib puag ncig.
Txhim kho thiab kev tsim kho
1. Inlet Sealing: Cov inlet ntawm tawg-pov thawj lub koob yees duab yuav tsum tau muab ntim nrog lub nplhaib roj hmab sealing. Nws raug txwv kom siv lwm txoj hauv kev xws li kev sau sealing kua nplaum thiab asbestos hlua hloov; Nws raug txwv los sau cov khoom hauv kab noj hniav los tiv thaiv kom tsis txhob tawg-pov thawj kev ua tau zoo; Nws txwv tsis pub pov tseg lub nplhaib sib khi thiab qhov sib txuam compression txiv ntoo ntawm qhov inlet rau qhov yooj yim ntawm kev sib txuas.
2. Kab pw: galvanized steel kav lossis txuas hniav yog siv rau xaim, thiab cov cables nyob deb ntawm cov chaw tawg thiab cov roj teeb meem phom sij. Cov pa roj sib txawv siv cov khoom sib txawv. Laim roj teeb hluav taws xob yog pw hauv av los yog cable trench, thiab ib puag ncig hnyav yog pw ntawm phab ntsa.
3. Cov Khoom Siv Hloov Chaw: Cov chaw teeb tsa yuav tsum zam cov chaw muaj cov av noo, cov plua plav, huab cua sov heev, thiab hluav taws xob txias heev, thiab hluav taws xob txias heev.
Kev siv thiab txij nkawm
1. Kev soj ntsuam txhua hnub: thaum kev tshuaj xyuas txhua hnub thiab kev saib xyuas kev ceev, kev tawg-pov thawj lub koob thaij duab yuav tsum zam kom ntau li ntau tau. Yog tias nws yuav tsum tau qhib, lub zog yuav tsum tau txiav tawm ua ntej. Yog tias qhov tawg-pov thawj hauv tsev tau qhib, kev tawg-pov thawj saum npoo yuav tsum muaj tiv thaiv kom raug thiab tsis raug puas. Thaum lub sijhawm saib xyuas, kev tawg-pov thawj saum npoo yuav tsum tau muab tso rau upward thiab yuav tsum tsis ncaj qha rau hauv av.
2. Cov tshuaj ntsuab-pov thawj, cov ntaub ntawv pov thawj plua plav, thiab cov khoom siv tshuaj tiv thaiv corrosion, vim tias cov khoom siv tau zoo dua qub, nws yuav muaj cov khoom siv ncaj qha, nws yuav muaj cov khoom siv ncaj qha, nws yuav muaj cov khoom siv ncaj qha, nws yuav muaj cov khoom siv ncaj qha rau cov khoom tawg. Yog li ntawd, nws yog ib qho tsim nyog los tsom rau cov dej noo-pov thawj, cov ntaub ntawv pov thawj plua plav, thiab kev tiv thaiv xeb.
3. Kev tiv thaiv xob laim thiab kev tawm tsam kev tawm tsam: Qhov kev tiv thaiv hluav taws xob tseem ceeb tiv thaiv kev tiv thaiv greading grounding network rau cov khoom lag luam. Ib qho chaw ywj pheej tiv thaiv tsawg dua 1 Ohm yuav tsum tau ua raws li lub khoos phis tawm hauv lub cev. Kev coj ua ntawm kev sib xyaw ntawm cov xob laim tiv thaiv kev ua haujlwm tam sim no nrog lub zog hluav taws xob kev tiv thaiv kev cuam tshuam nrog cov khoom siv. Kev cuam tshuam los tiv thaiv feem ntau yog cais cov hluav taws xob muaj zog thiab muaj zog, cais cov hluav taws xob sib cav sib ceg, thiab nruj me ntsis ua raws cov kev sib tw nrog kev sib txuas lus thiab kev lag luam hluav taws xob.
4. Kev Tu Tus Kws Tshaj Lij: Kev tshawb xyuas kev tshaj lij thiab kev saib xyuas cov kws tshaj lij hluav taws xob ntawm cov neeg siv hluav taws xob xaus kev ua pov thawj.
