Yuav ua li cas mus xyuas lub cav nrog ib tug multimeter? (3 txoj kev qhia)
Txheem
Lub cev muaj zog tsis zoo tuaj yeem ua rau muaj teeb meem ntau. Txoj kev no koj yeej tsis paub thaum twg koj yuav tsum tau kuaj xyuas koj lub cav. Yog vim li cas hnub no peb yuav saib yuav ua li cas los xyuas lub cav nrog ib tug multimeter. Txawm li cas los xij, rau cov txheej txheem no, koj yuav xav tau qee qhov kev txawj DIY. Nrog qee qhov kev txawj DIY thiab kev ua kom zoo, koj tuaj yeem ua tiav txoj haujlwm yooj yim heev.
Feem ntau, txhawm rau ntsuas lub cev muaj zog, koj yuav tsum xub muab lub multimeter rau hauv hom tsis kam. Tom qab ntawd xyuas cov motor terminals thiab cov xov hlau. Lub hom phiaj yog sim cov windings rau qhov qhib lossis luv luv.
Ntxiv nrog rau txoj kev tau piav qhia saum toj no, muaj ob txoj hauv kev uas peb tuaj yeem kuaj lub tshuab hluav taws xob. Ntawm no peb tab tom tham txog tag nrho peb qhov kev kuaj lub cev muaj zog. Yog li cia peb pib.
Test 1: Sib piv qhov voltage hla lub capacitor terminals nrog rau qhov siv voltage
Thaum txuas zoo, qhov voltage ntawm lub capacitor davhlau ya nyob twg yuav tsum yog 1.7 npaug ntawm qhov voltage ntawm lub hwj chim mov. Yog tias koj tau txais kev nyeem ntawv raws li qhov piv tau hais los saum toj no, qhov ntawd txhais tau hais tias lub cev muaj zog tau txais qhov tseeb voltage. Rau qhov kev kuaj lub cev muaj zog, peb yuav siv ob lub multimeters; Circuit Tester A thiab Circuit Court Tester B.
Kauj Ruam 1: Txheeb xyuas qhov hluav taws xob hluav taws xob nrog lub ntsuas hluav taws xob A.
Raws li nyob rau hauv daim duab saum toj no, ua ntej txuas cov kev xeem liab ua rau cov hlau liab; txuas lub xov tooj dub mus rau lub xov hlau dub. Qhov no yog cov txheej txheem rau Circuit Court tester A. Lub multimeter yuav tsum nyob rau hauv AC voltage hom. Ua ntej txuas lub multimeter mus rau lub cev muaj zog, koj yuav tsum ua qhov tsim nyog rau qhov multimeter. Yog tias koj ua raws li cov kauj ruam no kom raug, ces koj yuav tsum tau txais qhov voltage ntawm lub hwj chim mov. Yog tias koj siv 100V AC lub cev muaj zog, koj yuav tau txais 100V ntawm lub multimeter.
Kauj Ruam 2: Txheeb xyuas qhov voltage ntawm lub capacitor terminals siv lub ntsuas hluav taws xob B.
Tam sim no siv Circuit Tester B los xyuas qhov voltage hla lub capacitor terminals. Txuas lub xov tooj liab mus rau lub xov tooj liab. Tom qab ntawd txuas cov kev sojntsuam dub rau cov hlau dawb. Tam sim no xyuas qhov voltage nrog ib tug multimeter. Yog tias txhua qhov kev sib txuas zoo, koj yuav tau txais kev nyeem ntawv 1.7 npaug ntawm kev nyeem ntawv lub zog.
Piv txwv li, yog tias koj siv lub 100V lub cev muaj zog rau qhov kev sim no, lub multimeter yuav nyeem 170V.
Thaum koj tau txais kev nyeem ntawv ntawm 1.7 npaug ntawm lub zog muaj peev xwm, nws txhais tau hais tias lub cev muaj zog khiav ib txwm. Txawm li cas los xij, yog tias koj tsis tau txais qhov kev nyeem ntawv no, qhov teeb meem yuav nyob nrog koj lub cav.
Kuaj 2: xyuas cov hluav taws xob uas nqa los ntawm lub cable
Txhua yam faulty xov hlau los yog connectors yuav ua rau lub cav malfunction. Yog li ntawd, nws yog qhov zoo tshaj plaws los xyuas cov xov hlau thiab kev sib txuas ua ntej kos cov lus xaus. Nrog rau txoj kev no, peb yuav mus xyuas seb lub cev muaj zog Circuit Court qhib los yog luv luv nrog ib qho yooj yim continuity xeem.
Kauj Ruam 1 - Tua lub zog
Ua ntej, tua lub hwj chim. Lub zog tsis tas yuav tsum tau ua thaum ua qhov kev xeem txuas ntxiv.
Kauj ruam 2 - Ua cov kev sib txuas raws li daim duab
Kos daim duab saum toj no thiab txuas C thiab D Circuit Court tester feem. Txhawm rau ua qhov no, koj yuav tsum txuas cov hlau lead liab C rau cov hlau dub thiab cov hlau lead D liab liab. Tam sim no txuas ob qhov dub probes C thiab D mus rau qhov kawg ntawm qhov txuas txuas ntxiv. Yog tias muaj kev tawg ntawm lub voj voog nyob rau hauv kev sim, lub multimeters yuav pib beeping.
Nco ntsoov: Thaum kuaj xyuas cov xov hlau, nco ntsoov xaiv qhov chaw qhib ze ntawm lub cav. Thaum txuas cov sensors rau cov xov hlau, xyuas kom tseeb tias lawv txuas raug raug.
Test 3: Lub cev muaj zog winding resistance test
Hauv qhov kev xeem no, peb yuav ntsuas lub cev muaj zog winding tsis kam. Tom qab ntawd peb yuav muab piv nrog cov nqi ntawm lub cev muaj zog winding qhov tseem ceeb. Tom qab ntawd, peb tuaj yeem tshawb xyuas qhov xwm txheej ntawm lub cav los ntawm ob qhov txiaj ntsig.
Kauj Ruam 1 - Tshem tag nrho cov khoom xaiv xaiv
Ua ntej, tshem tawm cov khoom ntxiv los ntawm lub cev muaj zog, xws li cov capacitors thiab cov hlua txuas ntxiv.
Kauj ruam 2 - Teeb koj lub multimeter
Tam sim no teeb koj cov multimeters rau hom kev tiv thaiv. Yog tias koj nco qab, hauv ob qhov kev xeem dhau los, peb teeb lub multimeters rau hom voltage. Tab sis tsis nyob ntawm no.
Kauj Ruam 3 - Txuas cov sensors
Txuas ob qhov kev sim dub ua rau cov hlau dub. Tam sim no txuas cov hlau lead liab ntawm Circuit Court tester E rau cov hlau liab. Tom qab ntawd txuas cov hlau lead liab ntawm F Circuit Court tester rau cov hlau dawb. Yog tias koj tseem tsis meej pem, kawm daim duab qhia saum toj no. (1)
Kauj Ruam 4 - Tshawb xyuas thiab Sib Piv Kev Nyeem Ntawv
Kev nyeem ntawv multimeter yuav tsum yog 170 ohms, yog tias peb siv lub tshuab hluav taws xob 100 volt, qee zaum cov kev nyeem ntawv no tuaj yeem tsawg dua 170 ohms, piv txwv li, nrog ib qho luv luv Circuit Court, kev nyeem ntawv yuav tsawg dua 170 ohms. Txawm li cas los xij, yog tias cov windings puas lawm, kev nyeem ntawv yuav tsum muaj ntau tshaj li ob peb txhiab ohms.
Hauv qhov piv txwv saum toj no, peb siv lub tshuab hluav taws xob 100V.Tab sis thaum nws los txog rau lwm cov motors, koj yuav tsum paub txog cov nqi ntsuas nyob ntawm tus qauv. Sim tshawb hauv online lossis nug cov chaw tsim khoom. Tom qab ntawd sib piv ob qhov txiaj ntsig. (2)
Kuv yuav ua li cas yog tias lub cav ua tsis tiav cov kev ntsuam xyuas saum toj no?
Yog tias koj lub cav ua tsis tiav cov kev sim no, ces ib yam dab tsi tsis ncaj ncees lawm nrog nws. Yog vim li cas rau qhov teeb meem no yuav yog ib tug phem lub cev muaj zog los yog faulty Cheebtsam xws li; tsis zoo relays, keyboards, cables los yog tsis ncaj ncees lawm voltage. Txawm li cas los xij, koj muaj lub cev muaj zog.
Txawm li cas los xij, nyob ntawm txhua qhov kev sim, cov kev daws teeb meem yuav txawv. Piv txwv li, yog tias lub cev muaj zog tsis ua tiav qhov kev xeem thib 1, qhov teeb meem yog nyob rau hauv cov kab hluav taws xob lossis cov capacitors. Ntawm qhov tod tes, yog tias lub cev muaj zog ua tsis tau qhov kev xeem thib 2, qhov teeb meem yog nyob rau hauv lub connector lossis cable. Rau kev nkag siab zoo, ntawm no yog cov lus qhia yooj yim.
Yog tias lub cav ua tsis tiav Test 1Tej zaum koj yuav tau hloov cov xaim thiab cov capacitors.
Yog tias lub cav ua tsis tiav Test 2Tej zaum koj yuav tau hloov lub connector thiab cable.
Yog tias lub cav ua tsis tiav Test 03tej zaum koj yuav tau hloov lub cev muaj zog.
Cov teeb meem siv tshuab xws li lub pob tsis ua haujlwm tuaj yeem cuam tshuam koj lub cav. Qhov xwm txheej no tshwm sim vim muaj ntau tshaj axial lossis radial load. Tej zaum koj kuj yuav tau kuaj xyuas cov teeb meem no. Yog li, ua raws li cov kauj ruam no.
1 ruam: Ua ntej, tshem lub gearbox thiab lub cev muaj zog.
2 ruam: Tom qab ntawd tig lub ncej clockwise thiab counterclockwise.
3 ruam: Yog tias koj hnov cov kev sib txhuam txawv txav los yog lub suab zoo li cov ncej tig, qhov no yog qhov qhia txog kev tsis ncaj ncees lossis kev puas tsuaj. Hauv qhov no, tej zaum koj yuav tau hloov lub cev muaj zog.
Summing txog
Peb txoj kev no yog cov kev daws teeb meem zoo tshaj plaws rau kev sim cov tshuab hluav taws xob. Yog tias koj ua raws li cov kauj ruam no kom raug, koj tuaj yeem txiav txim siab qhov xwm txheej ntawm txhua lub cav. Txawm li cas los xij, yog tias koj tseem muaj qhov tsis txaus ntseeg, xav rov qab xyuas tsab xov xwm dua.
