Yuav kuaj xyuas lub tshuab hluav taws xob li cas rau kev ua haujlwm hauv tsev?
Ib qho ntawm cov chaw ua haujlwm nyob rau hauv daim ntawv teev cov kev ua haujlwm tsis zoo ntawm lub tsheb yog nyob ntawm kev tawg ntawm cov khoom siv hluav taws xob. Cov ntsiab lus tseem ceeb tshaj plaws rau kev ua haujlwm ntawm cov khoom siv hluav taws xob yog lub roj teeb thiab lub tshuab hluav taws xob, uas ua haujlwm nrog kev sib koom ua ke tas li.
Ntawm peb lub vev xaib Vodi.su, peb tau hais ntau zaus txog cov qauv ntawm lub roj teeb thiab lub tshuab hluav taws xob, txog lawv cov kev tawg thiab kev kuaj mob. Nyob rau hauv tsab xov xwm niaj hnub no, kuv xav kov ib lub ntsiab lus uas tseem tsis tau hais txog ntawm peb cov peev txheej: yuav ua li cas txheeb xyuas koj lub tshuab hluav taws xob rau kev ua haujlwm hauv tsev?
Feem ntau cov tshuab hluav taws xob tsis ua haujlwm thiab lawv qhov tshwm sim
Lub tshuab hluav taws xob, feem ntau, muaj cov khoom siv hluav taws xob thiab cov khoom siv tshuab. Yog li, raws li peb tau sau ua ntej, lub tshuab hluav taws xob rub lub tshuab hluav taws xob tau tsav los ntawm lub crankshaft los ntawm txoj siv lub sijhawm. Raws li, lub pulley yuav ua tsis tau raws sij hawm, thiab feem ntau nws yog cov kabmob uas tawg. Ib tug kos npe rau ntawm xws li ib tug tawg yuav yog ib tug squeak los ntawm lub engine compartment, siv slip, thiab ib tug voltage poob nyob rau hauv lub network.
Lub tshuab hluav taws xob ntawm lub rooj sib dhos muaj cov hauv qab no:
- rotor thiab stator;
- rectifier diodes;
- voltage regulator;
- txhuam los ua ke nrog graphite txhuam uas nyob rau hauv kev sib cuag nrog lub rotor rings;
- diode choj.
Feem ntau, cov tswv tsheb yuav tsum tau hloov cov alternator txhuam, uas hnav tawm. Nws tseem yuav tsum tau saib xyuas kev ncaj ncees ntawm cov xov hlau thiab kev sib cuag. Vim yog hnav ntawm lub rotor ncej bearing thiab xoob bracket fastenings, koj tuaj yeem ntsib cov rotor tsoo lub stator ncej.
Cov tsos mob ntawm kev puas tsuaj hauv electromechanical tuaj yeem yog cov hauv qab no:
- lub alternator xa cov nqi them tam sim no rau lub roj teeb, tab sis lub roj teeb tsis them tag nrho;
- tas li flashing ntawm lub roj teeb them lub teeb;
- txo qhov voltage;
- taub hau glow dimly;
- luv circuits hauv hluav taws xob thaiv, thiab lwm yam.
Nws yog qhov tseeb tias cov cim pom tseeb ntawm kev ua haujlwm tsis zoo tsis tuaj yeem tsis quav ntsej. Yog tias tsis ntsuas lub sijhawm, qhov tshwm sim tuaj yeem yog qhov txaus ntshai tshaj plaws, mus txog qhov hluav taws xob ntawm cov xaim hluav taws xob thiab tig koj lub tsheb mus rau hauv lub roob ntawm cov hlau crumpled. Peb twb tau sau rau ntawm Vodi.su txog yuav ua li cas xyuas lub tshuab hluav taws xob yam tsis tau tshem tawm. Niaj hnub no peb yuav tham txog txoj hauv kev los xyuas nws cov kev ua tau zoo hauv tsev.
Tshawb xyuas lub tshuab hluav taws xob dismantled
Yog tias koj qhov kev paub txog hluav taws xob engineering nyob rau theem high school, nws yog qhov zoo dua los tso siab rau txoj haujlwm no rau cov kws tshaj lij.
Thawj qhov uas yuav tsum tau kuaj xyuas yog txhuam hnav. Lawv tuaj yeem hnav tawm ob qho tib si rau cov laj thawj ntuj thiab vim qhov tsis zoo ntawm lub rotor ncej. Rau txhua lub tsheb qauv, cov lus qhia rau lub tshuab hluav taws xob yuav tsum qhia qhov siab tshaj plaws ntawm cov txhuam hniav. Yog tias nws qis dua, nws yog lub sijhawm los hloov cov txhuam hniav. Txhua lub khw muag khoom pib muag cov txhuam txhuam nrog cov hlua khi thiab cov hlua khi.
Cov kauj ruam kev kuaj mob yuav tsum tau ntsuas lub stator, rotor thiab diode choj windings nrog ib tug multimeter. Hloov cov tester mus rau ohmmeter hom thiab txuas nws cov kev sojntsuam rau cov zis ntawm txhua daim hlau winding. Cov qib kuj yuav tsum nyob rau hauv 0,2 ohms. Yog tias nws siab dua lossis qis dua, ces lub winding yuav tsum tau hloov. Qhov kev tawm tsam ntawm lub davhlau ya nyob twg ntawm cov stator sib dhos thiab ib qho ntawm cov hlau winding ntawm cov cuab yeej ua haujlwm yog nyob ib ncig ntawm 0,3 Ohm.
Kev kuaj lub rotor yog qhov nyuaj dua.
Cov txheej txheem kuaj mob:
- peb hloov cov tester mus rau qhov kev ntsuas kev tiv thaiv thiab ntsuas nws ntawm qhov kev tiv thaiv winding ntawm lub rotor sib dhos;
- Yog tias qhov ntsuas no nyob hauv thaj tsam ntawm 2,3-5 ohms, ces txhua yam zoo nrog lub winding, tsis muaj kev cuam tshuam luv luv lossis qhib kev sib cuag;
- tsis kam qis dua tus nqi teev - muaj luv luv Circuit Court;
- tsis kam siab tshaj 5 ohms - kev sib cuag tsis zoo nrog lub nplhaib, winding breakage.
Muab lub tester rau hauv hom kev kuaj mob tam sim no thiab siv 12 volts (lossis 24 yog tias koj tab tom kuaj xyuas lub tsheb hloov pauv) rau cov hlua khi. Qhov zoo tshaj plaws, qhov excitation winding ntawm lub rotor noj tsis ntau tshaj 4,5 Amps thiab tsis pub tsawg tshaj peb.
Qhov teeb meem kuj tseem nyob hauv kev sib cais. Yog hais tias lub rwb thaiv tsev tsis zoo nyob rau hauv ib txwm muaj, ces ib tug pa 40-watt incandescent teeb txuas nrog lub nplhaib thiab rau hauv av yuav tsum tsis txhob hlawv. Yog hais tias nws glows dimly thiab blinks, ces muaj tam sim no xau.
Nco qab tias tag nrho cov haujlwm no tau ua tiav tom qab tshem tawm ntawm lub tshuab hluav taws xob thiab nws cov khoom siv ib nrab disassembly. Tus choj diode tuaj yeem kuaj xyuas ob qho tib si ntawm lub tsheb thiab ntawm lub tshuab hluav taws xob tshem tawm. Lub ntsiab lus ntawm qhov kev xeem yog ntsuas lub zog tam sim no thaum txuas cov multimeter probes rau tus choj terminals thiab hauv av. Yog tias qhov hluav taws xob siab tshaj 0,5 volts, thiab lub zog tam sim no siab dua 0,5 milliamps, ces ib qho ntawm ob yam: muaj teeb meem nrog lub rwb thaiv tsev, los yog nws yog lub sij hawm hloov cov diodes.
Ntau tus tswv tsheb hauv lub nkas-las tuaj yeem nrhiav tau ib qho tshwj xeeb ntxiv kev sojntsuam - ib qho clip uas muab tso rau ntawm lub cable thiab xyuas cov recoil tam sim no. Nws yog qhov parameter no uas yog lub luag haujlwm rau recharge lub roj teeb thaum lub tsheb tsiv. Yog tias tus nqi no qis dua tus nqi nominal, ces muaj teeb meem nrog lub tshuab hluav taws xob lossis tus choj diode.
tshawb pom
Raws li koj tuaj yeem pom, kuaj xyuas lub tshuab hluav taws xob nrog cov txheej txheem improvised tsis yog ib txoj haujlwm yooj yim. Yog tsis muaj cov cuab yeej tshwj xeeb, qhov ua rau ntawm kev puas tsuaj tsuas yog txiav txim siab los ntawm "poke method". Cov teeb meem zoo li no tau ntsib, ua ntej ntawm tag nrho cov, los ntawm cov tswv ntawm cov tsheb hauv tsev tsim nyob rau hauv 90s ntawm XNUMXs thaum ntxov.
Yog tias koj muaj lub tsheb uas nyuam qhuav yuav, peb yuav tsis pom zoo nrog kev ua txhaum ntawm hluav taws xob ntawm koj tus kheej, vim qhov no yuav ua rau tsis muaj kev lees paub tseeb. Ua tib zoo mloog cov ntsaws ruaj ruaj uas nyob ntawm lub tshuab hluav taws xob vaj tsev. Koj tsis tuaj yeem ua rau lawv puas tsuaj. Nws yog qhov yooj yim dua rau xa daim ntawv tsis txaus siab rau lub khw uas koj yuav lub cuab yeej. Yog tias lub tshuab hluav taws xob tseem nyob hauv warranty, koj yuav tsum hloov nws yog tias pom muaj qhov tsis xws ntawm lub Hoobkas.
