Tshawb xyuas thiab txiav txim seb lub tshuab hluav taws xob pib lub tshuab hluav taws xob puas zoo lossis phem. Ua ntej, rub tawm cov tub ntxhais hlau txav tau thiab lub caij nplooj ntoos hlav los ntawm qhov kawg, hlau lub solder ntawm lub tshuab hluav taws xob hloov lub thawv txuas kom tshem tawm cov hluav taws xob hloov hluav taws xob coil txuas, thiab tom qab ntawd tshem tawm cov ntsia hlau kho ntawm lub thawv hloov kom cais lub thawv hloov ntawm lub kauj. plhaub,
Rub lub hloov ncej sib dhos ib feem tawm ntawm cov hlau thaiv ntawm lub tsev.
(1) Kev tshuaj xyuas cov khoom siv tshuab.
Kev koom tes ntawm cov tub ntxhais hlau txav tau yooj yim, hloov ncej thiab lub coil vaj tse yuav tsum ua kom muaj kev txav mus los. Kev sib cuag ntawm qhov chaw hauv qhov hloov pauv thiab ntawm tus ncej tuaj yeem ua tau
Xuab zeb nrog metallographic sandpaper. Yog hais tias lub tswm ciab tau kub hnyiab thiab daig, nws yuav tsum tau kho los yog hloov.
Lub phaj tiv tauj yuav tsum tiaj tus, sab rau cov menyuam yuav tsum tiaj tus, lub tog raj kheej kawg lub caij nplooj ntoos hlav yuav tsum tsis tu ncua, thiab qhov siab ntawm ob qhov sib tiv tauj hauv lub thawv hloov yuav tsum yog tib yam.
(2) Kev tshuaj xyuas ntawm electromagnetic hloov coil.
Kev tshuaj xyuas ntawm lub tshuab hluav taws xob hloov hluav taws xob feem ntau suav nrog: ① roj teeb tshuaj xyuas txoj kev; ② multimeter soj ntsuam txoj kev.
1) Cov txheej txheem kuaj roj teeb.
① Tshem tawm cov xaim ntawm lub tshuab hluav taws xob los ntawm lub davhlau ya nyob twg "M" ntawm qhov sib nqus hloov #, txuas 12V (los yog 24V, raws li xav tau) roj teeb ntawm lub davhlau ya nyob twg "S" thiab lub davhlau ya nyob twg "M" ntawm cov hlau nplaum, thiab nyob rau tib lub sij hawm txuas rau lwm cov hlau tsis zoo ntawm tus ncej ntawm lub roj teeb yog txuas nrog lub plhaub ntawm lub oob khab, tom qab lub hwj chim qhib, lub iav oob khab tuaj yeem raug thawb tawm sai sai mus rau qhov chaw ua haujlwm, uas qhia tau hais tias cov attracting kauj ntawm electromagnetic hloov yog ua haujlwm zoo.
② Tshem tawm sai sai ntawm lub roj teeb tsis zoo lub davhlau ya nyob twg mus rau lub tshuab hluav taws xob hloov hluav taws xob "M". Yog hais tias lub oob khab tsav lub iav nyob twj ywm rau hauv txoj hauj lwm thawb tawm, tuav coil yog qhov zoo.
Lus Cim: Ob qhov kev ntsuam xyuas saum toj no yuav tsum ua kom tiav hauv lub sijhawm luv luv kom tsis txhob hlawv lub kauj.
2) Multimeter soj ntsuam txoj kev.
Tshem tawm cov hlau nplaum hlau nplaum ntawm lub tshuab hluav taws xob hloov hluav taws xob ntawm lub tshuab hluav taws xob, txuas cov terminals "M" thiab "S" ntawm cov hluav taws xob hloov hluav taws xob nrog ob qhov kev sojntsuam ntawm multimeter, thiab kuaj xyuas lawv qhov tseem ceeb; Tom qab ntawd txuas lub multimeter mus rau lub terminals ntawm lub electromagnetic hloov raws li "M" thiab "S" terminals (uas yog, ob kawg ntawm lub tuav coil), thiab xyuas lawv kuj.
Fault diagnosis thiab tshuaj xyuas ntawm oob khab electromagnetic hloov 1. Tuav Coil Fault
Fault Performance:
Thaum lub oob khab tuav lub kauj yog qhib, luv luv, los yog tsis zoo hauv av, lub oob khab tsav lub iav ua ntu zus kais lub flywheel.
Yog vim li cas rau tsis ua hauj lwm:
Yog vim li cas rau qhov tshwm sim no yog tias thaum pib, cov tub ntxhais hlau txav tau yog nyiam los ntawm cov coil attraction, yog li ntawd lub ntsiab tiv tauj ncoo yog nyob rau hauv kev sib cuag nrog ob lub ntsiab terminals. Txawm li cas los xij,
Thaum lub sij hawm sib cuag, vim yog de-energization ntawm cov coil attracting, lub movable hlau tseem nyob ruaj ruaj nyob rau hauv qhov kev txiav txim ntawm tuav kauj, tab sis vim lub zog ntawm lub tuav kauj.
Kev ua txhaum, cov tub ntxhais hlau txav tau rov qab tau rov qab los ntawm qhov kev txiav txim ntawm lub caij nplooj ntoos hlav rov qab, uas cais lub ntsiab sib tiv tauj ntawm ob lub ntsiab terminals, thiab DC lub cev muaj zog yog de-energized. ib yam
, qhov attraction coil yog energized dua los nyiam cov tub ntxhais hlau txav mus rau qhov chaw uas lub ntsiab tiv tauj ncoo hu rau ob lub ntsiab terminals. Thaum lub sijhawm sib cuag, nqus
Cov hlau lead coil yuav raug de-energized dua, uas yuav cais cov ntaub ntawv tseem ceeb. Yog tias qhov no rov ua dua, yuav muaj lub suab "nias, nyem". 2. Suction coil tsis ua haujlwmGrass
Yog hais tias qhov attraction coil tawg, lub active hlau core yuav tsis tau attracted los ntawm tuav kauj thaum pib. Thaum pib, yog hais tias nws yog ib tug pib Circuit Court nrog ib tug pib relay, tsuas yog nias lub suab ntawm tus pib relay hu, tab sis lub starter tsis ua hauj lwm. Tau kawg, hom kev ua tsis tiav no yog nyob ntawm qhov chaw ntawm kev tshem tawm cov roj teeb tsis ua haujlwm.
Yog vim li cas rau qhov tshwm sim no yog tias thaum pib, cov tub ntxhais hlau txav tau yog nyiam los ntawm cov coil attraction, yog li ntawd lub ntsiab tiv tauj ncoo yog nyob rau hauv kev sib cuag nrog ob lub ntsiab terminals. Txawm li cas los xij,
Thaum lub sij hawm sib cuag, vim yog de-energization ntawm cov coil attracting, lub movable hlau tseem nyob ruaj ruaj nyob rau hauv qhov kev txiav txim ntawm tuav kauj, tab sis vim lub zog ntawm lub tuav kauj.
Kev ua txhaum, cov tub ntxhais hlau txav tau rov qab tau rov qab los ntawm qhov kev txiav txim ntawm lub caij nplooj ntoos hlav rov qab, uas cais lub ntsiab sib tiv tauj ntawm ob lub ntsiab terminals, thiab DC lub cev muaj zog yog de-energized. ib yam
, qhov attraction coil yog energized dua los nyiam cov tub ntxhais hlau txav mus rau qhov chaw uas lub ntsiab tiv tauj ncoo hu rau ob lub ntsiab terminals. Thaum lub sijhawm sib cuag, nqus
Cov hlau lead coil yuav raug de-energized dua, uas yuav cais cov ntaub ntawv tseem ceeb. Yog tias qhov no rov ua dua, yuav muaj lub suab "nias, nyem". 2. Suction coil faulty.
Yog hais tias qhov attraction coil tawg, lub active hlau core yuav tsis tau attracted los ntawm tuav kauj thaum pib. Thaum pib, yog hais tias nws yog ib tug pib Circuit Court nrog ib tug pib relay, tsuas yog nias lub suab ntawm tus pib relay hu, tab sis lub starter tsis ua hauj lwm. Tau kawg, hom kev ua tsis tiav no yog nyob ntawm qhov chaw ntawm kev tshem tawm cov roj teeb tsis ua haujlwm.
