Yuav ua li cas rau cov khoom hluav taws xob ua raws li NEMA cov qauv
{{0 {}} nkag siab txog cov qauv nema cuam tshuam
Nema tau tso ntau cov qauv npog ntau yam los ntawm cov khoom siv hluav taws xob, tshuab rau cov qauv hluav taws xob yog los xyuas seb NEMA cov qauv siv rau koj cov khoom {1} Tus qauv muaj xws li:
Nema 250: Txheem rau cov ntaub thaiv (rau dej quav (rau dej, plua plav - pov thawj, thiab tawg - cov ntaub ntawv pov thawj).
Nema mg1: Qauv rau cov motors thiab tshuab hluav taws xob .
Nema 12: Nkag rau cov qauv siv rau cov cuab yeej siv hauv kev lag luam ib puag ncig .
Nema 4x: Nkag mus rau tus qauv rau kev ua kom thaj chaw thaj chaw .
Nema 6: Qauv rau dej tsis muaj dej thiab hmoov av - ntawv pov thawj hluav taws xob .
2. Cov khoom lag luam los ua kom tau raws li cov qauv
Tsim koj cov khoom lag luam raws li cov qauv nema {0} Hais txog cov khoom siv hluav taws xob ntxiv, thiab cov khoom siv hluav taws xob kom tau ua kom muaj qee yam kev tiv thaiv kev corrosion lossis siab kub.
{{03. Xaiv qhov kev xeem thiab ntawv pov thawj lub cev
Nema nws tus kheej tsis muaj cov kev pab cuam tshuam tab sis koom tes nrog rau cov qauv NEMA nrog cov khoom lag luam hauv nroog
{{0 {}}} Kev Ua Khoom Kuaj Cov Khoom
Kev xeem yog tus yuam sij kom ntseeg tau tias cov khoom lag luam sib ntsib ntawm cov khoom lag luam, thiab kev ntsuas hluav taws xob feem ntau, thiab cov khoom lag luam hluav taws xob ua tau raws li Nema cov kev xav tau {}}
5. Tau txais daim ntawv pov thawj tsim nyog
Txawm hais tias Nema tsis muab ntawv pov thawj ncaj qha, ib zaug cov khoom lag luam dhau ntawm cov ntawv pov thawj tseem ceeb kom paub meej tias cov khoom lag luam uas muaj feem xyuam rau kev lag luam thiab muaj txiaj ntsig rau kev lag luam thiab muag khoom .
{{06. Ua raws li Nema cov hloov tshiab tsis tu ncua thiab cov kev xav tau
NEMA cov qauv txuas ntxiv nrog kev txhim kho thev naus laus zis thiab hloov kho cov qauv no yog li ntawd, kom tau txais lawv cov khoom lag luam tshiab kom tsis txhob ua raws li kev ua raws li .
Cov Nema cov ntawv pov thawj thiab cov ntawv thov txheem
Cov Motors thiab Generators: Nema tau muab ntau cov qauv ntsig txog cov khoom siv xws li cov khoom siv xws li cov khoom muaj peev xwm, hloov pauv, thiab cov tshuab hluav taws xob kom paub meej txog lawv qhov kev nyab xeeb thiab kev nyab xeeb {}}
Khoom Siv Hluav Taws Xob: Cov cuab yeej xws li cov thawv xa hluav taws xob, hluav taws xob hloov, thiab vaj huam sib luag txhua yam yuav tsum tau ntsib NEMA cov qauv los xyuas kom lawv tau txais txiaj ntsig zoo nyob rau hauv lub u} s {1}.
Cov khoom siv tswj: Xws li cov khoom siv rau lub cev, kev hloov ntau zaus, thiab lwm yam kev cai uas yuav xav ua raws li NEMA cov cai ntawm kev ua haujlwm thiab kev ua haujlwm.
