Cov zis ntawm lub tshuab hloov pauv feem ntau yog qhia hauv amperes, uas yog qhov tseem ceeb tsuas yog tus nqi tam sim no uas lub tsev muaj peev xwm muab tau rau tag nrho cov khoom siv uas txuas rau hauv hluav taws xob. Qhov no yog ib qho tseem ceeb ntawm daim duab vim qhov tseeb tias OEM alternators feem ntau tsis muaj teeb meem los lis kev thauj khoom ntxiv los ntawm cov khoom siv tom qab muag thiab hloov kho dua tshiab.
Thaum qhov ntawd tshwm sim, thiab koj lub tshuab hluav taws xob tso tawm tsis tuaj yeem ua kom tau raws li qhov xav tau ntawm koj lub tshuab hluav taws xob, koj tuaj yeem ntsib txhua yam ntawm lub teeb taws tsis pom kev mus rau teeb meem kev tsav tsheb loj. Cia ib leeg, qhov teeb meem no thaum kawg yuav ua rau lub tshuab hluav taws xob hlawv tag nrho.
Tau kawg, muaj qhov sib txawv ntawm qhov hloov pauv lub amperage "kev ntsuas" thiab tus nqi tam sim no uas nws tuaj yeem muab tau ntawm qhov nrawm nrawm, uas yog vim li cas nws tseem ceeb kom muaj kev nkag siab tag nrho ntawm kev nyeem alternator tso tawm cov qhab nia yog tias koj muaj ntau lub zog- tshaib plab tom qab cov khoom nruab.
Thaum qhov kev ntsuas tso tawm ntawm lub tshuab hloov pauv muab rau koj lub tswv yim ntawm qhov nws tau tsim los tso tawm, tib txoj hauv kev kom pom tias lub tshuab hloov pauv muaj peev xwm ua tau yog kuaj nws. Txog qhov kawg, koj tuaj yeem ntsuas qhov tso tawm tiag tiag ntawm lub tshuab hloov pauv raws li kev simulated load, uas tso cai rau koj kom tau txais lub tswv yim ntawm qhov nws muaj peev xwm muab tso rau hauv lub ntiaj teb tiag tiag.
Alternator tso zis ntsuas thiab lub ntiaj teb tiag
Lo lus " alternator output" yog hais txog ob qhov sib txawv, tseem muaj feem cuam tshuam, cov ntsiab lus. Qhov thib ib yog lub alternator tso zis ntsuam xyuas, uas yog tus nqi ntawm tam sim no uas ib chav tsev muaj peev xwm ua tau ntawm ib tug tshwj xeeb rotational ceev. Piv txwv li, 100A alternator muaj "rated" tso zis ntawm 100A, uas txhais tau hais tias nws muaj peev xwm muab 100A thaum lub alternator ncej tig ntawm 6,000 RPM.
Lwm yam uas cov khoom siv hluav taws xob tuaj yeem xa mus yog tus nqi tam sim no uas ib chav ua tau tsim tawm txhua lub sijhawm, uas yog lub luag haujlwm ntawm lub cev muaj peev xwm ntawm lub alternator, kev sib hloov ceev ntawm lub tswv yim, thiab lub sijhawm xav tau ntawm lub tshuab hluav taws xob.
Kev nkag siab Alternator tso zis kev ntsuas
Thaum koj hnov tias lub alternator yog "nyob ntawm 100A," nws tuaj yeem txhais tau tias muaj ntau yam sib txawv nyob ntawm seb koj tau txais cov ntaub ntawv los ntawm qhov twg. Tib lub sijhawm uas qhov no yog qhov muaj txiaj ntsig tiag tiag yog thaum lub chaw tsim khoom hloov pauv lossis rov tsim kho siv lo lus "kev ntsuas" hauv nws lub peev xwm, uas tau txhais los ntawm cov ntaub ntawv thoob ntiaj teb xws li ISO 8854 thiab SAE J 56.
Nyob rau hauv ISO 8854 thiab SAE J 56, alternator kuaj thiab daim ntawv lo cov qauv qhia tau hais tias "cov zis tawm" ntawm lub alternator yog tus nqi tam sim no uas nws muaj peev xwm ua tau ntawm 6,000 RPM. Txhua tus qauv kuj qhia txog ntau yam ntawm lwm qhov nrawm uas lub tshuab hloov pauv yuav tsum tau sim ntawm thiab txhais tau tias "tsis ua haujlwm" thiab "siab tshaj plaws" tso tawm ntxiv rau "tso zis tawm.”
Txawm hais tias alternator manufacturers, rebuilders, thiab lwm tus neeg feem ntau xa mus rau cov rated tso zis nyob rau hauv promotional cov ntaub ntawv, ob lub ISO thiab SAE xav tau ib hom ntawv "IL / IRA VTV," qhov twg IL yog qhov tsawg, los yog tsis muaj zog, amperage. tso zis, IR yog qhov ntsuas amperage tso zis, thiab VT yog qhov ntsuas hluav taws xob.
Qhov no ua rau cov kev ntsuas zoo li "50/120A 13.5V," uas feem ntau tau luam tawm lossis ntaus cim rau ntawm lub tsev ntawm lub tshuab hloov pauv.
Kev txhais lus Alternator tso zis ntsuas
Cia peb ua piv txwv los ntawm ntu dhau los thiab tshuaj xyuas nws:
50/120A 13.5V
Vim peb paub tias ob qho tib si ISO thiab SAE cov qauv hu rau hom "IL / IRA VTV" ua tau yooj yim zoo nkauj los txhais qhov kev ntaus nqi no.
Ua ntej, peb yuav saib IL, uas, qhov no, yog 50. Qhov ntawd txhais tau hais tias lub tshuab hloov pauv no muaj peev xwm tso tawm 50A ntawm qhov ntsuas "tsawg", uas yog 1, 500 RPM lossis " lub idle ceev ntawm lub cav,”nyob ntawm seb tus qauv koj tab tom ua nrog.
Tus lej tom ntej yog 120, uas yog "IR" lossis qhov tso tawm amperage ntawm " ntsuas" nrawm. Hauv qhov no, lub tshuab hluav taws xob no muaj peev xwm tso tawm 120A @ 6,000 RPM. Txij li qhov no yog qhov ntsuas " ntsuas" nrawm, tus lej no feem ntau yog siv rau lub tshuab hloov pauv cov zis tawm.
Tus lej kawg yog 13.5V, uas yog "VT" lossis qhov hluav taws xob uas lub tshuab hloov pauv tau tuav thaum lub sijhawm kuaj. Txij li thaum lub tshuab hluav taws xob tso tawm tuaj yeem sib txawv ntawm ob qho tib si nce thiab nqis los ntawm 13.5V hauv qhov xwm txheej tiag tiag, nws qhov kev tso tawm tiag tiag yuav txawv ntawm qhov tsis ua haujlwm thiab cov lej ntsuas.
Alternator Output Supply and Demand
Nrog rau txhua yam hauv siab, nws tseem ceeb heev kom nkag siab tias qhov tso zis ntawm lub tshuab hluav taws xob yog khi rau qhov kev xav tau ntawm cov hluav taws xob hluav taws xob ntxiv rau nws qhov peev xwm thiab qhov ceev uas nws cov khoom nkag tau tig los ntawm ib qho twg. moment.
Nyob rau hauv lub ntsiab lus, thaum lub siab tshaj plaws alternator tso zis yog nyob ntawm qhov kev sib hloov ceev ntawm lub tswv yim ncej, qhov tseeb tso zis yog load-nyob ntawm seb. Qhov ntawd txhais tau hais tias lub tshuab hluav taws xob yuav tsis tsim hluav taws xob ntau dua li qhov raug hu los ntawm qhov kev xav tau ntawm lub tshuab hluav taws xob tam sim no.
txhais tau tias, hauv ntiaj teb tiag tiag, yog tias thaum lub tshuab hluav taws xob tsis muaj zog tuaj yeem ua teeb meem los ntawm kev ua tsis tau raws li qhov xav tau ntawm koj lub tshuab hluav taws xob, lub tshuab hluav taws xob ntau dhau los sawv cev rau ntau lub peev xwm khib nyiab. Piv txwv li, lub tshuab hluav taws xob tso zis siab tuaj yeem muaj peev xwm tso tawm siab tshaj 300A, tab sis nws yuav tsis muab ntau qhov amperage ntau dua li cov Tshuag 80A yog tias tag nrho cov hluav taws xob puas tau sim kos.
Koj Puas Xav Tau Ntau Qhov Tawm Tawm Alternator?
Feem ntau, cov alternators raug hloov vim kev hnav thiab tsim kua muag. Internal Cheebtsam tsuas yog hnav tawm, yog li qhov zoo tshaj plaws ntawm qhov kev txiav txim yog los hloov nws nrog ib tug tshiab los yog rebuilt chav tsev uas ua raws li tib yam tso zis ntaus ntawv. Muaj cov xwm txheej uas nws pheej yig dua los tsim kho lub alternator es tsis txhob yuav lub tsev tshiab lossis rov tsim dua tshiab, tab sis qhov ntawd yog qhov sib tham sib txawv.
Tseem muaj cov xwm txheej uas lub tshuab hluav taws xob tuaj yeem hlawv tawm vim qhov xav tau ntau dhau lub sijhawm ntev. Qhov no feem ntau tsis siv rau cov tsheb uas muaj lub tshuab hluav taws xob hauv lub tsheb thiab tsis muaj lwm yam khoom siv ntxiv, tab sis nws tuaj yeem nkag mus rau hauv kev ua si sai sai thaum koj pawg rau ntau dua thiab ntau dua cov khoom siv zog tshaib plab.
Thaum lub tshuab hluav taws xob zoo li kub hnyiab tau sai dua li qhov xav tau, thiab lub tsheb muaj lub tshuab hluav taws xob muaj zog tom qab muag, lossis lwm yam khoom siv zoo sib xws, tom qab ntawd kev hloov pauv nrog cov txiaj ntsig ntau dua tuaj yeem kho qhov teeb meem.
