Thaum koj xaiv lub tshuab hluav taws xob, koj tsis tsuas yog muab piv rau cov zis hluav taws xob. Koj kuj yuav tsum xav txog kev ua tau zoo, kev saib xyuas, qhov loj me, kev ntseeg tau, thiab ntev - nqi khiav hauj lwm. Cov khoom siv hlau nplaum tas mus li siv cov hlau nplaum tas mus li los tsim cov hlau nplaum, yog li lawv tsis xav tau qhov kev tawm dag zog sab nraud. Qhov no pab txo qis zog thiab ua kom yooj yim rau cov qauv. Hauv phau ntawv qhia no, koj yuav kawm vim li cas cov tshuab hluav taws xob hlau nplaum ruaj khov siv rau hauv cua, hydro, marine, off-grid, thiab muaj OEM fais fab tshuab.
Dab tsi yog ib qho khoom siv hluav taws xob tas mus li?
Lub tshuab hluav taws xob hlau nplaum ruaj khov (PMG) yog lub tshuab hluav taws xob hloov hluav taws xob rau hauv hluav taws xob siv cov hlau nplaum ruaj khov es tsis txhob siv hluav taws xob los tsim cov hlau nplaum.
Nws Ua Haujlwm Li Cas?
Nws yooj yim dua li qhov koj xav. Cov hlau nplaum tas mus li yog ntsia ncaj qha mus rau lub rotor. Thaum lub rotor tig, siv los ntawm cua, dej, los yog lub cav, lub magnetic teb txiav los ntawm tooj liab windings nyob rau hauv lub stator, tsim hluav taws xob tam sim no. Qhov ntawd yog nws.
Tsis muaj hluav taws xob sab nraud. Tsis txhuam. Tsis muaj rings.
Tsis zoo li cov tshuab hluav taws xob sib xyaw uas xav tau cov txheej txheem sib cais los ua kom lub zog sib nqus, PMGs yog tus kheej - siv los ntawm cov hlau nplaum lawv tus kheej, ua rau lawv muaj txiaj ntsig zoo dua, txhim khu kev qha, thiab yooj yim dua los tswj.

Sab saum toj daim ntawv thov ntawm Permanent Magnet Generators thoob plaws kev lag luam
PMGs tsis yog rau ib qho kev lag luam xwb. Nov yog qhov uas koj yuav pom lawv xa cov txiaj ntsig tiag:
Cua Turbines
Qhov no yog daim ntawv thov loj tshaj plaws. Ib qho 15 MW offshore turbine xav tau 600+ kg ntawm NdFeB hlau nplaum. Kev tsav ncaj qha PMGs tshem tawm lub gearbox, txo cov ntsiab lus tsis ua haujlwm thiab txiav cov nqi tu.
Hydroelectric zog Systems
Yog tias koj qhov project cuam tshuam nrog qis- nrawm, siab- lub zog torque, PMGs yog qhov haum. Me- nplai hydro yog ib qhov ceev tshaj plaws - loj hlob PMG ntu thoob ntiaj teb tam sim no.
Marine & Offshore
Cov dej qab ntsev hnyav ib puag ncig xav tau kev ntseeg siab tshaj txhua yam. PMGs nrog corrosion{1}}resistant SmCo los yog coated NdFeB hlau nplaum yog tam sim no tus qauv ntawm LNG cov cab kuj thiab cov nkoj tawm ntug dej hiav txwv.
Tawm -Grid & Microgrid Systems
Lub zog khiav hauv thaj chaw deb? PMGs yog qhov zoo tagnrho. Nyob ze - xoom txij nkawm txhais tau tias tsis muaj kev pabcuam mus rau qhov chaw nyuaj, qhov txiaj ntsig tseem ceeb rau cov phiajcim kob thiab cov phiaj xwm hluav taws xob nyob deb nroog.
Muaj Standby & Backup Fais Fab
Cov tsev kho mob, cov chaw khaws ntaub ntawv, thiab cov nroj tsuag semiconductor tuaj yeem them tsis taus sijhawm. PMGs xa cov hluav taws xob huv, ruaj khov tso tawm cov chaw no nyob ntawm txhua lub sijhawm.
Yuav Ua Li Cas Xaiv Qhov Zoo Tshaj Lij Tshaj Lij Tshaj Lij rau koj lub tshuab hluav taws xob
Xaiv cov hlau nplaum tsis ncaj ncees lawm tsis yog ua mob rau kev ua haujlwm xwb; nws tuaj yeem ua rau tsis muaj kev puas tsuaj rau koj lub tshuab hluav taws xob. Ntawm no yog tsib yam uas koj xav tau kom tau txais txoj cai ua ntej muab qhov kev txiav txim.
Qib (Magnetic Strength)
Pib ntawm no. Rau feem ntau cov cua thiab kev siv PMG, NdFeB qib N35-N52 npog feem ntau ntawm cov kev cai. Yog tias koj lub tshuab hluav taws xob khiav ntawm qhov kub siab, koj yuav xav tau siab siab -qib EH lossis UH txhawm rau tiv thaiv demagnetisation hauv qab load. Tau txais qhov yuam kev no yog qhov yuam kev ntau tshaj plaws thiab raug nqi ntau tshaj peb pom.
Kev khiav hauj lwm qhov kub thiab txias
Koj cov hlau nplaum yuav tsum tswj qhov kub siab tshaj plaws hauv koj lub tshuab hluav taws xob - tsis yog qhov kub thiab txias xwb. Thaum tshav kub kub tsim los ntawm windings, kev sib txhuam, thiab koj qhov chaw ua haujlwm. Txo qhov ntsuas no, thiab koj cov hlau nplaum ntsiag to poob kev ua haujlwm dhau sijhawm mus txog thaum nws ua tsis tiav.
Kev coercivity (Hc)
Nyob rau hauv lub tshuab hluav taws xob, koj cov hlau nplaum tas li raug tawm tsam cov hlau nplaum uas tsim los ntawm stator tam sim no. Coercivity ntsuas koj cov hlau nplaum lub peev xwm los tiv thaiv demagnetisation nyob rau hauv cov xwm txheej ntawd. Nco ntsoov qhia koj qhov yuav tsum tau Hc yam tsawg kawg nkaus, tshwj xeeb tshaj yog rau siab - daim ntawv thov fais fab.
Nto Txheej
Txheej txheej yog nyob ntawm koj ib puag ncig:
Nickel (Ni)- kev tiv thaiv tus qauv rau feem ntau hauv tsev thiab kev lag luam kev lag luam
Zinc (Zn)- tus nqi- muaj txiaj ntsig zoo rau cov cheeb tsam uas xav tau tsawg dua
Epoxy- txoj kev xaiv zoo rau marine, offshore, los yog siab -humidity installations
Hla cov kauj ruam no nyob rau hauv ib puag ncig dej ntsev yog ib txoj hauv kev lav rau corrosion tsis ua hauj lwm.
Magnetization Direction
Axial, radial, lossis diametrical, koj qhov kev taw qhia magnetization yuav tsum phim koj rotor tsim raws nraim. Qhov no tsis yog ib yam uas yuav twv tau. Qhia koj cov duab kos duab nrog koj tus neeg muag khoom thiab paub meej tias qhov kev qhia no ua ntej pib tsim khoom.
FAQ
