Txoj Kev Ncaj Ncees Teeb Meem thiab Kev Tshawb Fawb Kev Tshawb Fawb Txog Tshiab Lub Zog Tsheb Tsav Tsheb
Raws li cov ntaub ntawv thiab cov ntaub ntawv muag tawm los ntawm lub tuam txhab suav teb, cov khoom muag thiab kev muag khoom ntawm tshiab lub zog tsheb nyob rau hauv Suav teb tau 794,000 thiab 777,000 feem pua ntawm 2017, ib xyoo nce ntawm 53.8% thiab 53.3% feem. Kev tsim tawm thiab kev txiav txim siab muag thawj zaug nyob hauv lub ntiaj teb rau peb xyoo sib law liag. Txoj kev loj hlob sai ntawm cov tsheb tshiab tau coj zoo tshaj plaws rau txoj kev tsav tsheb, thiab kev tsim kho lub tshuab ua haujlwm tau ua qhov chaw kub tshaj plaws hauv kev lag luam.
Tam sim no tus txheej xwm ntawm kev tsim kho tshuab hluav taws xob
Tam sim no, cov tsav tsheb yog raug faib ua DC motors, AC motors thiab hub motors; ntawm lawv, DC thiab AC motors yuav muab faib ntxiv. Tam sim no, txoj kev lag luam them nqi ze rau AC asynchronous motors, cov hlau nplaum sib txuas ntawm cov hluav taws xob sib txuas thiab hloov cav tsis sib haum. Los ntawm kev sib piv thiab kev txheeb xyuas ob peb lub cav ua ke (saib Cov Rooj Sab 1), cov lag luam uas muaj peev xwm ua tau zoo tshaj plaws muaj qhov ua tau zoo ntawm kev ua haujlwm siab, kev khiav ceev, me me, lub zog hnyav, siab muaj zog thiab tsis raug nqi, thiab ua hluav taws xob ntshiab tsav tsheb. Lub ntsiab tsav tsheb hauv kev ua lag luam.
Los ntawm cov kev xav ntawm kev lag luam kev txhawb zog, tshiab lub zog neeg caij tsheb cov khoom siv feem ntau siv AC induction motors thiab cov hlau nplaum synchronous mus tas li. Ntawm lawv, tas li cov hlau nplaum synchronous cav siv ntau dua, vim tias lawv cov khwv ceev ceev thiab kev ua haujlwm yog tus neeg siab, tab sis qhov system uas kim heev magnet khoom NdFeB yog xav tau. Qee cov European thiab Asmeskas tsheb siv AC induction motors, feem ntau vim yog kev tsis tshua muaj cov khoom siv tsawg. Yuav kom txo tau cov nqi ntawm lub cav, qhov tsis zoo mas yog tias qhov kev khiav ceev yog tsawg, qhov ua tau tsawg tsawg, thiab yuav tsum muaj kev ua tau zoo dua tus thawj tswj hwm ua kom tau zoo.
Nrog rau txoj kev loj hlob sai ntawm lub zog tshiab tsheb tsheb, lub lag luam muaj peev xwm ntawm tsav tsav tsheb loj loj, yog xav kom nkag mus ntawm ntau lub tuam txhab thiab peev. Lub tshuab hluav taws xob nyob hauv lub tshuab hluav taws xob ua lag luam tas li ntawm cov khoom tsav tsheb hauv tsev thiab nyob sab nrauv muaj nyob hauv Table 2. Tag nrho, Tuam Tshoj tsav tsheb tau ua kom tau zoo, thiab muaj kev ywj siab tsim cov khoom tsim nyog raws li cov kev xav tau ntawm ntau lub zog tshiab tsheb. Qee qhov kev ua tau zoo tshaj plaws tau pom txog qib siab thoob ntiaj teb ntawm tib lub zog. Txawm li cas los xij, tseem muaj qee qhov sib txawv ntawm cov teb chaws txawv teb chaws hais txog qhov ceev tshaj plaws, muaj zog ntim thiab ua haujlwm.
