Shenhai Explosion-Proof
Ua ntej lub los ua ke ntawm explosion-proof fais fab khoom, Nws tseem ceeb heev rau cov tswv los xyuas cov components tau utilized, Pab kom lawv ua raws li cov designated tsim thiab los ua ke specifications.
1. Soj ntsuam ntawm self-manufactured Components
a. Kev Soj Ntsuam Zoo
Txhua tus kheej manufactured tivthaiv yuav tsum muaj ib daim ntawv qhia txog kev soj ntsuam los yog daim ntawv pov thawj los ntawm cov preceding manufacturing theem.
b. Visual Component Inspection
Kuv. Components yuav tsum tau undamaged. Los ua ke yog txwv tsis pub muaj cov dents, tawg, los sis zoo ib yam li puas.
Ii. Explosion-proof qhov chaw yuav tsum defect-dawb. Yog hais tias defects raws li kho criteria, muaj cai kho, raws li rov soj ntsuam ua ntej los ua ke (Yuav tsum tau kho thiab cov kev kho mob yog xav paub meej ntxiv nyob rau Seem 1 2.5.2 Tshooj 2).
iii. Cov components yuav tsum tsis txhob exhibit tej yam tshwm sim los yog xeb. Qhov chaw uas muaj rust los yog pleev xim rau tawg-pov thawj qhov chaw, Los yog cov uas tsis tau tu los yog coated nrog cov xeb grease, tsis tsim nyog rau los ua ke.
c. Kev soj ntsuam ntawm Cavity Components
Kuv. Cavities yuav tsum tau devoid ntawm cov ntaub ntawv txawv teb chaws. Tag nrho cov khib nyiab, Xws li hlau shavings thiab fabric scraps, yuav tsum tau cleared ua ntej los ua ke.
Ii. Lub cavity yuav tsum tau coated nrog los tiv thaiv rust paint, thiab tawg-proof qhov chaw, nrog arc-resistant paint. Coating yuav tsum tau thov ua ntej los ua ke yog tsis tuaj.
d. Soj ntsuam ntawm Insulating Components
Kuv. Xyuas kom meej txog cov khoom siv insulating cov qib kawm (Kuv, II, IIa, thiab IIb).
Ii. Kuaj daim ntawv qhia txog qhov chaw insulation kuj rau yas casings (tsis tshaj 10^9 ohms).
e. Qhov no mus xyuas qhov chaw
Xyuas cov functionality mus rau qhov chaw rau smooth lag luam, Ensuring lawv yuav tsis jammed los yog nrov.
1. Lees Txais Cov Nyiaj Uas Yuav Tau Los
a. Cov Kev Tsim Nyog Tau Txais Kev
Kuv. Muas components yuav tsum tuaj nrog ib manufacturer ntawv pov thawj ntawm conformity.
Ii. Cov qauv thiab plahaum dimensions ntawm cov components yuav tsum align nrog cov khoom los ua ke yuav tsum tau.
b. Visual and Internal Inspections
Kev soj ntsuam rau muas components mirror cov neeg rau qhov chaw.
c. Kev Kawm Txog Yam Xeeb Txawm Muaj
Kev ntsuam xyuas rau lwm qhov chaw sourced components muaj xws li:
Kuv. Mechanical kev ntsuam xyuas hais txog qhov luaj li cas thiab ntim ringness, ua los ntawm batch sampling.
Ii. Hluav Taws Xob Kev Ntsuam Xyuas Hluav, nrog rau kev hloov haujlwm thiab sampling ntawm twg uas muaj rov electronic components.
iii. Insulation kev ntsuam xyuas, zoo ib yam li cov kev tiv thaiv, nrog batch sampling.
Dhau li ntawm cov txheej txheem aforemented, Kev soj ntsuam ntxiv rau muas khoom raws li cov qauv raws li cov khoom.
Tsis hais seb components yog kev tsim txom los yog imported, apart from batch kuaj, Ib tug neeg soj ntsuam ntawm txhua yam khoom yog mandatory.
Component verification yog ib txoj kev tseem ceeb heev ua ntej assembling tawg-proof fais fab tuag, tseem ceeb heev rau enhancing los ua ke zoo, ensuring tub ntxhais functionality, thiab ruaj ntseg tawg-proof kev ruaj ntseg. No task zov high-level xim thiab precision.
