Txhawm rau tshuaj xyuas lub tshuab hluav taws xob hauv tsev, koj yuav xav tau multimeter. Koj tuaj yeem tshawb xyuas qhov ywj pheej ntawm txoj siv tawv, them rov qab, diode choj, stator, kabmob thiab txhuam.
Qee lub sij hawm ib tus neeg nyiam tsheb tau ntsib nrog cov lus nug ntawm kev kuaj lub tshuab hluav taws xob ntawm nws lub tsheb. Tom qab txhua qhov, nws yog ib qho tseem ceeb heev kom ceeb toom raws sij hawm thiab tshem tawm qhov ua tsis zoo uas tuaj yeem ua rau lub roj teeb tsis ua haujlwm thiab teeb meem nrog kev pib lub cav. Qhov kev xaiv zoo tshaj plaws yuav tso cov teeb meem no rau tus kws tshaj lij, tab sis yog tias qhov no tsis tuaj yeem, koj tuaj yeem kuaj lub tshuab hluav taws xob koj tus kheej nyob hauv tsev, qhov loj tshaj plaws yog muaj multimeter muaj.
Yuav kuaj lub tshuab hluav taws xob li cas tsis tshem tawm ntawm lub tsheb
Hauv qhov no, koj tuaj yeem tshawb xyuas lub tshuab hluav taws xob thiab lub teeb liab kom them. Nws yog qhov tsim nyog los txuas ib qho multimeter rau lub roj teeb thiab ntsuas qhov ntsuas hluav taws xob hauv hom sib txawv nrog lub cav khiav. Txhawm rau ua qhov no, koj yuav tsum muab lub teeb hluav taws xob: qhib / kaw cov taws teeb, nias lub thawv roj, tig lub qhov cub, thiab lwm yam. Yog tias, sim hauv txoj kev no, koj tuaj yeem pom tias qhov hluav taws xob tau ceev nyob rau hauv 14-14, 2 Volts, tom qab ntawd peb tuaj yeem nyab xeeb hais tias txhua yam yog nyob rau hauv kev txiav txim nrog lub tshuab hluav taws xob thiab kev sib txuas. Yog tias muaj lub siab dhia ntau dua li 0.5-1V, muaj kev ua rau lub cev tsis zoo.
Lwm tus tuaj yeem tuaj yeem kuaj lub tshuab hluav taws xob tau li cas
Ua ntej, xyuas txoj siv tawv: qee zaum nws yog txhua yam hais txog xoob. Txhawm rau rhuav tshem lub tshuab hluav taws xob nyob hauv tsev, nws tsim nyog kuaj lub rotor. Txhawm rau ua kom zoo li no, koj yuav tsum nrhiav seb qhov twg yog qhov tsis kam ntawm cov nplhaib khi stator. Yog tias cov ntsuas no tsis tshaj 5-10 ohms, tom qab ntawd txhua yam yog nyob rau hauv kev txiav txim siab, yog tias daim duab no ntau dua, nws yog qhov ua tau tias muaj kev tawg ntawm cov cua qhov chaw. Tom ntej no, siv multimeter, koj yuav tsum kuaj xyuas qhov tawg ntawm txhua lub nplhaib mus rau hauv av. Yog tias muaj qhov tawm tsam ntawm lub rotor thiab txhua lub nplhaib, ces tsis tas yuav tham txog kev tawg, yog tias tsis muaj qhov tsis kam, ces muaj kev sib tsoo. Nrog txoj kev tawg zoo li no, nws tsis tuaj yeem kho cov tshuab hluav taws xob hauv tsev.
Nws yog qhov yooj yim los xyuas cov diode choj. Raws li koj paub, nws suav nrog 6 diodes - peb qhov zoo thiab peb qhov tsis zoo. Nws yog ib qho tsim nyog yuav tsum txiav tawm txhua cov kev coj ua los ntawm cov paib nrog diodes thiab kev sim: muab cov ntawv pov thawj rau cov diode coj, thiab tom qab ntawd rov ua qhov kev sim, hle lawv. Lub teeb tsa suab nrov yuav tsum hnov ntawm ib txoj hauj lwm thiab tsis nyob rau lwm qhov. Yog tias squeak tau hnov hauv ob qho kev qhia, peb tab tom tham txog qhov rhuav tshem ntawm diode, uas txhais tau tias koj yuav tau hloov nws. Tab sis tsis muaj kev paub txaus, qhov no yog qhov nyuaj ua, yog li koj yuav tsum hloov tag nrho cov phaj diode.
Tus stator yuav tsum tau kuaj xyuas kom zoo - yuav tsum tsis muaj qhov kub nyhiab lossis puas rau qhov cua. Tom qab ntawd koj yuav tsum tau ntiv nplhaib qhov winding nrog multimeter. Raws li rau cov kabmob, tsis muaj dab tsi yuav cuam tshuam rau lawv cov kev sib hloov dawb: yuav tsum tsis muaj suab nrov thiab rov qab sib zog. Kev txhuam txhuam yuav tsum tsuas yog ua raws li 5 hli ntawm ntawm npoo xwb. Tej daim, qhwv thiab caj dab yog cais tawm. Yog tias muaj qhov sib txawv, nws yog qhov zoo dua los hloov nws.
