Nqe Lus Nug 1: Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm hom lub cev muaj zog ntawm kev ua haujlwm?

Teb: Hom lub cev muaj zog no muaj ntau yam kev ua tau zoo - ntsig txog qhov zoo. Ua ntej, nws tuaj yeem muab kev sib hloov ceev, uas yog qhov tseem ceeb rau cov ntawv thov uas yuav tsum tau txav nrawm. Piv txwv li, hauv qee cov cuab yeej hluav taws xob xws li kev xyaum, kev sib hloov ceev tso cai rau kev nrawm nrawm los ntawm ntau yam ntaub ntawv. Thib ob, nws tuaj yeem tsim lub zog siab rau nws qhov loj. Qhov no txhais tau tias nws muaj peev xwm xa tau ib qho tseem ceeb ntawm kev sib hloov quab yuam, ua rau nws ua haujlwm xws li tsav tsheb screws lossis siv cov khoom siv me me uas yuav tsum tau kov yeej qee qhov kev tawm tsam. Tsis tas li ntawd, nws lub peev xwm ua haujlwm ntawm ob qho tib si ncaj qha tam sim no (DC) thiab hloov pauv tam sim no (AC) muab kev yooj yim heev. Qhov no ua rau nws tsim nyog rau ntau qhov chaw siv hluav taws xob, txawm tias nws yog lub roj teeb - siv DC qhov chaw nyob hauv cov khoom siv nqa tau lossis AC cov khoom siv hauv tsev.

 

Nqe Lus Nug 2: Puas muaj kev txwv ntawm kev siv hluav taws xob?

Teb: Muaj qee qhov kev txwv txog kev siv hluav taws xob. Piv nrog rau qee yam ntawm cov motors tshwj xeeb uas tsim los rau cov kev siv ua haujlwm siab, hom lub cev muaj zog no yuav tsis zoo li lub zog. Tus tsim uas tso cai rau nws ua haujlwm ntawm DC thiab AC muaj qee yam kev lag luam tawm. Lub winding configuration thiab txoj kev nws ua hauj lwm yuav ua rau kom lub zog ntau dua poob, tshwj xeeb tshaj yog nyob rau hauv tej yam kev mob. Piv txwv li, thaum khiav ntawm qis qis los yog nyob rau hauv lub teeb loads, nws yuav tsis hloov hluav taws xob lub zog rau hauv txhua yam zog raws li ib co mob siab rau DC los yog AC motors. Txawm li cas los xij, hauv cov ntawv thov uas nws cov yam ntxwv tshwj xeeb (xws li kev kub ceev thiab kev ua haujlwm dual - tam sim no) yog qhov tseem ceeb tshaj qhov kev ua tau zoo ntawm lub zog, cov kev txwv no tuaj yeem ua tau.

 

Nqe Lus Nug 3: Nws lub neej ntev npaum li cas piv rau lwm cov motors?

Teb: Lub neej ntev ntawm lub cev muaj zog tuaj yeem cuam tshuam los ntawm ntau yam. Feem ntau, nws yuav muaj lub neej luv luv piv rau qee qhov tshwj xeeb motors. Ib qho ntawm cov laj thawj tseem ceeb yog kev tsim hluav taws xob ntau dua vim nws cov qauv tsim thiab kev ua haujlwm zoo. Kev ua haujlwm tas mus li, tshwj xeeb tshaj yog nyob rau hauv cov khoom hnyav lossis kev kub ceev, tuaj yeem ua rau lub cev muaj zog tuaj yeem ua kom sov sai dua. Thaum tshav kub kub yog ib qho tseem ceeb hauv kev txo qis lub neej ntawm cov khoom siv hluav taws xob vim nws tuaj yeem ua rau hnav thiab tsim kua muag ntawm cov windings, bearings, thiab lwm yam. Tsis tas li ntawd, cov txhuam hniav (yog tias nws muaj cov qauv siv txhuam) yuav tsum hnav lub sijhawm, uas tuaj yeem txwv nws txoj sia. Txawm li cas los xij, kev saib xyuas kom zoo, xws li kev tu ib txwm, lubrication, thiab ua kom lub qhov cua kom zoo, tuaj yeem pab ua kom nws lub neej ntev.

 

Nqe Lus Nug 4: Cov yam ntxwv kev nyab xeeb dab tsi lossis kev txiav txim siab yuav tsum tau coj mus rau hauv tus account thaum siv lub cev muaj zog no?

Teb: Thaum siv hom no lub cev muaj zog, muaj ntau yam kev xav txog kev nyab xeeb. Txij li thaum nws tuaj yeem tsim kom muaj cua sov sai sai, kev ua kom sov kom zoo yog qhov tseem ceeb. Yuav tsum muaj qhov cua txaus kom tiv thaiv kom tsis txhob muaj cua sov, uas tuaj yeem ua rau lub cev tsis zoo xwb tab sis kuj ua rau muaj hluav taws kub. Yog hais tias lub cev muaj zog muaj ib tug txhuam hniav tsim, muaj kev pheej hmoo ntawm sparking. Qhov no txhais tau hais tias nws yuav tsum tau siv nyob rau hauv ib puag ncig uas muaj cov khoom siv hluav taws xob tsawg tsawg los yog yuav tsum tau ceev faj kom tsis txhob ignition. Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm hluav taws xob kev nyab xeeb, kev rwb thaiv tsev kom zoo thiab hauv av yuav tsum tau ua kom muaj kev tiv thaiv hluav taws xob. Lub cev muaj zog yuav tsum raug ntsia raws li cov cai hluav taws xob thiab cov qauv tsim kom muaj kev nyab xeeb ntawm cov neeg siv thiab ib puag ncig ib puag ncig.

 

Nqe Lus Nug 5: Hauv cov kev lag luam tshwj xeeb lossis cov ntawv thov twg yog lub tshuab no feem ntau siv?

Teb: Lub cev muaj zog no feem ntau siv rau ntau yam kev lag luam thiab kev siv. Hauv kev lag luam khoom siv hauv tsev, nws tuaj yeem pom hauv cov khoom siv me me xws li lub tshuab nqus tsev, tshuab ntxhua khaub ncaws, thiab khoom noj khoom haus. Kev sib hloov ceev ceev thiab qhov loj me me yog qhov zoo - haum rau cov ntawv thov no qhov chaw feem ntau txwv thiab kev ua haujlwm ceev yog xav tau. Hauv kev lag luam cov cuab yeej hluav taws xob, nws yog siv hauv cov cuab yeej siv tes xws li kev xyaum thiab cov ntsia hlau hluav taws xob. Lub peev xwm los tsim kom muaj zog torque ua rau nws tsim nyog rau kev tsav tsheb screws thiab drilling qhov hauv cov khoom sib txawv. Tsis tas li ntawd, nws tuaj yeem siv rau hauv qee qhov kev lag luam me me uas qhov yooj yim ntawm kev khiav hauj lwm ntawm ob qho tib si DC thiab AC yog qhov zoo, xws li hauv qee cov khoom siv txawb lossis cov khoom siv txawb uas yuav tsum tau siv los ntawm ntau qhov chaw nyob ntawm qhov xwm txheej.

 

Nqe Lus Nug 6: Tus nqi ntawm lub cev muaj zog li cas piv rau lwm yam zoo sib xws - ua haujlwm motors?

Teb: Nyob rau hauv cov nqe lus ntawm tus nqi, lub cev muaj zog no feem ntau muaj qhov zoo dua lwm cov motors nrog cov yam ntxwv zoo sib xws. Nws tus qauv tsim yooj yim, uas tso cai rau nws ua haujlwm ntawm DC thiab AC, feem ntau ua rau nws tsis tshua muaj nqi los tsim. Cov txheej txheem tsim khoom rau hom lub cev muaj zog tuaj yeem ua kom yooj yim dua piv rau qee qhov nyuaj thiab tshwj xeeb motors. Cov nqi no - kev ua tau zoo ua rau nws yog qhov kev xaiv txaus nyiam rau cov ntawv thov uas tus nqi yog qhov tseem ceeb, xws li hauv huab hwm coj - tsim cov khoom siv. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tus nqi mus sij hawm ntev yuav tsum tau txiav txim siab, suav nrog cov khoom lag luam xws li kev siv hluav taws xob thiab kev ua neej, uas yuav cuam tshuam rau tag nrho cov nqi - kev ua tau zoo ntawm cov khoom lag luam lub neej voj voog.

 

Nqe Lus Nug 7: Hom kev tu lub cev no feem ntau xav tau dab tsi?

Teb: Lub cev muaj zog no feem ntau xav tau ntau hom kev saib xyuas. Yog tias nws muaj cov qauv siv txhuam, cov txhuam hniav yuav tsum tau kuaj xyuas tsis tu ncua rau kev hnav thiab hloov thaum tsim nyog. Cov txhuam hniav tuaj yeem hnav dhau lub sijhawm vim muaj kev sib txhuam ntawm cov txhuam hniav thiab cov commutator. Lub commutator nws tus kheej kuj yuav tsum tau tshuaj xyuas thiab ntxuav kom ntseeg tau tias muaj hluav taws xob zoo. Hais txog kev saib xyuas dav dav, kev tu lub cev tsis tu ncua kom tshem tawm cov plua plav thiab cov khib nyiab yog qhov tseem ceeb. Plua plav tuaj yeem sau rau ntawm lub windings thiab lwm qhov chaw, uas tuaj yeem cuam tshuam rau lub cev muaj zog kev ua tau zoo thiab cua sov dissipation. Lubrication ntawm cov bearings kuj tseem tsim nyog los txo kev sib txhuam thiab ua kom muaj kev ua haujlwm zoo. Tsis tas li ntawd, raws li tau hais ua ntej, kev ua kom qhov cua kom zoo yog qhov tseem ceeb rau kev ua kom sov, yog li txhua qhov vents lossis cua txias yuav tsum tau kuaj xyuas kom paub tseeb tias lawv tsis thaiv.
