Hauv kev lag luam thoob ntiaj teb niaj hnub no, kev xa tawm cov khoom yuav tsum ua raws li ntau yam ntawv pov thawj thiab cov qauv. Ib daim ntawv pov thawj tseem ceeb yog daim ntawv pov thawj CE, uas ua kom cov khoom ua tau raws li qhov tsim nyog kev nyab xeeb, kev noj qab haus huv, thiab ib puag ncig cov cai hauv European Economic Area (EEA). Hauv tsab xov xwm no, peb yuav tshawb xyuas qhov tseem ceeb ntawm daim ntawv pov thawj CE thiab nws qhov kev sib raug zoo rau EMC kuaj thiab electromagnetic cuam tshuam (EMI) cov qauv. Raws li lub tuam txhab ua lag luam thiab kev pab tswv yim thev naus laus zis tshwj xeeb hauv EC brushless motors, kiv cua, thiab cov kev daws teeb meem ntse, PBM tau cog lus los muab cov khoom zoo tshaj - raws li cov cai CE.
Nkag siab txog CE Certification
Daim ntawv pov thawj CE yog qhov yuav tsum tau ua rau cov khoom muag hauv EEA. Nws qhia tau tias cov khoom ua tau raws li qhov tseem ceeb ntawm kev noj qab haus huv, kev nyab xeeb, thiab kev tiv thaiv ib puag ncig cov qauv tsim los ntawm European Union (EU). Los ntawm kev tau txais daim ntawv pov thawj CE, cov neeg tsim khoom pom lawv txoj kev mob siab rau kev xa cov khoom muaj kev nyab xeeb thiab txhim khu kev qha rau cov neeg siv khoom.
PBM muaj ntau yam ntawm 9 cov khoom lag luam loj, suav nrog kab pheeb ces kaum axial, rov qab thiab rau pem hauv ntej nkhaus centrifugal, radial, ib qho inlet thiab dual inlet blowers, tangential, thiab cross flow kiv cua. Tag nrho peb cov khoom tau lees paub nrog CE thiab ROHS, thiab qee qhov kuj tau txais ntawv pov thawj UL. Cov ntawv pov thawj no xyuas kom meej tias peb cov khoom ua tau raws li cov qauv siab tshaj plaws ntawm kev nyab xeeb thiab zoo, ua rau lawv yooj yim recyclable thiab txo cov peev txheej pov tseg los ntawm kev rov ua dua, rov siv dua, thiab rov ua dua tshiab.
Ntawm PBM, peb siv zog rau kev sib txhuam txhuam tsis muaj hlau nplaum ruaj khov synchronous sab nraud rotor motors tsav ntau hom thiab qhov ntau thiab tsawg ntawm impellers. Peb cov saw hlau muaj txiaj ntsig zoo thiab txhim khu kev qha txhawb nqa peb pawg tsim khoom thiab kev tswj xyuas zoo hauv kev xa cov khoom ruaj khov nyob rau hauv kev sib tw ua ntej raws li tau cog lus tseg.
PBM lub zog- txuag cov kiv cua raug muag rau ntau tshaj tsib caug lub teb chaws thiab cheeb tsam thoob ntiaj teb, pab txhawb kev txhim kho ib puag ncig zoo thiab kev txuag nyiaj txiag.
Qhov tseem ceeb ntawm EMC Kev Xeem
Kev ntsuam xyuas EMC, tseem hu ua Electromagnetic Compatibility, yog hais txog kev ntsuam xyuas ntawm cov khoom siv hluav taws xob nyob rau hauv cov nqe lus ntawm Electromagnetic Interference (EMI) thiab Electromagnetic Susceptibility (EMS). Lub hom phiaj ntawm qhov kev ntsuam xyuas no yog txhawm rau ntsuas lub peev xwm ntawm ntau yam khoom siv hluav taws xob (xws li cov kab mob muaj sia nyob hauv kev nkag siab dav) kom nyob nrog lawv tus kheej ib puag ncig electromagnetic, kom ntseeg tau tias lawv ua haujlwm zoo yam tsis ua rau muaj kev cuam tshuam tsis zoo ntawm electromagnetic cuam tshuam rau lwm yam khoom siv hauv ib puag ncig. Nws yog ib qho tseem ceeb tshaj plaws ntsuas ntawm cov khoom zoo. Raws li cov kiv cua yog cov khoom siv tshuab, Electromagnetic compatibility (EMC) kev sim ua lub luag haujlwm tseem ceeb hauv cov txheej txheem CE. Nws ua kom ntseeg tau tias cov khoom siv hluav taws xob, xws li peb cov kiv cua EC, ua raws li cov qauv hluav taws xob thiab kev tiv thaiv kab mob. EMC kuaj ntsuas cov khoom muaj peev xwm ua haujlwm zoo yam tsis ua rau lossis cuam tshuam los ntawm electromagnetic cuam tshuam.
Electromagnetic cuam tshuam (EMI)
EMI hais txog kev cuam tshuam los ntawm cov hluav taws xob hluav taws xob hluav taws xob tawm los ntawm cov khoom siv hluav taws xob. Kev ua raws li cov qauv EMI yog qhov tseem ceeb los xyuas kom meej tias peb cov khoom tsis cuam tshuam nrog lwm cov khoom siv hluav taws xob lossis cuam tshuam lawv cov kev ua tau zoo. Cov khoom kuaj tseem ceeb rau EMI (Electromagnetic Interference) muaj xws li RE (Radiated Emissions), CE (Ua Cov Hluav Taws Xob), Harmonic, thiab Flicker.
Electromagnetic Susceptibility (EMS)
EMS, tseem hu ua Electromagnetic Susceptibility, hais txog lub peev xwm ntawm cov khoom siv hluav taws xob lossis cov tshuab ua haujlwm ib txwm nyob hauv ib puag ncig uas muaj kev cuam tshuam electromagnetic. EMS ntsuas qhov tsis kam ntawm lub cuab yeej lossis lub cev rau kev cuam tshuam sab nraud ntawm electromagnetic, thiab EMS siab dua qhia tias muaj kev tiv thaiv zoo rau kev cuam tshuam. Lub hauv paus ntsiab lus tom qab EMS suav nrog kev siv cov kev ntsuas tsim nyog electromagnetic shielding los txo qhov rhiab heev rau sab nraud electromagnetic cuam tshuam. Qhov no suav nrog kev siv cov khoom siv electromagnetic shielding, optimizing circuit layout, grounding plan, thiab grounding design kom txo tau qhov cuam tshuam ntawm electromagnetic cuam tshuam.
Cov khoom kuaj tseem ceeb rau EMS muaj xws li ESD (Electrostatic Discharge), EFT (Electrical Fast Transient), DIP (Voltage Dip), CS (Conducted Susceptibility), RS (Radiated Susceptibility), Surge (Lightning Surge), thiab PMS (Power Magnetic Susceptibility).
