Txav koj txhais tes me me thiab nyob deb ntawm kev cuam tshuam lub cev muaj zog?
1. Lub cev tsis tuaj yeem pib
1. Lub cev muaj zog tsis tig thiab tsis muaj suab nrov.Yog vim li cas yog tias muaj ob-theem lossis peb-theem qhib Circuit Court nyob rau hauv lub cev muaj zog fais fab mov lossis winding.Ua ntej kuaj xyuas cov khoom siv hluav taws xob.Yog tias tsis muaj qhov hluav taws xob hauv peb theem, qhov txhaum yog nyob rau hauv Circuit Court;Yog hais tias peb-theem voltages sib npaug, qhov txhaum yog nyob rau hauv lub cev muaj zog nws tus kheej.Lub sijhawm no, qhov kev tiv thaiv ntawm peb-theem windings ntawm lub cev muaj zog tuaj yeem ntsuas kom paub cov windings nrog qhib theem.
2. Lub cev muaj zog tsis tig, tab sis muaj lub suab "humming".Ntsuas lub davhlau ya nyob twg lub cev muaj zog, yog tias peb-theem voltage yog sib npaug thiab tus nqi ntsuas tuaj yeem txiav txim siab raws li qhov hnyav dhau.
Cov kauj ruam tshuaj xyuas yog: ua ntej tshem tawm cov load, yog tias qhov ceev thiab lub suab ntawm lub cev muaj zog yog qhov qub, nws tuaj yeem txiav txim siab tias cov khoom siv dhau los lossis cov khoom siv ntawm cov khoom tsis raug.Yog tias nws tseem tsis tig, koj tuaj yeem tig lub cev muaj zog ntawm tes.Yog tias nws nruj heev los yog tsis tuaj yeem tig, ntsuas peb theem tam sim no.Yog hais tias peb-theem tam sim no sib npaug, tab sis nws loj dua tus nqi ntsuas, nws yuav yog tias cov khoom siv ntawm lub cev muaj zog yog daig thiab lub cev muaj zog tsis muaj roj, bearing xeb lossis kev puas tsuaj loj, qhov kawg npog lossis roj npog yog ntsia dhau obliquely, lub rotor thiab lub puab bore collide (tseem hu ua cheb).Yog tias nws nyuaj rau tig lub cev muaj zog los ntawm txhais tes mus rau ib lub kaum ntse ntse lossis yog tias koj hnov ib lub suab "chacha" ib ntus, nws tuaj yeem txiav txim siab raws li cheb.
Cov laj thawj yog:
(1) Qhov sib txawv ntawm cov nplhaib sab hauv thiab sab nrauv ntawm cov kabmob loj heev, thiab cov kabmob yuav tsum tau hloov
(2) Cov kabmob chamber (cov kabmob lub qhov) loj dhau, thiab lub qhov taub sab hauv yog loj dhau vim hnav mus ntev.Kev ntsuas kub ceev yog electroplate ib txheej ntawm cov hlau los yog ntxiv lub tes tsho, los yog xuas nrig ntaus ib co ntsiab lus me me rau ntawm phab ntsa ntawm cov kabmob chamber.
(3) Cov ncej yog khoov thiab lub hau kawg yog hnav.
3. Lub cev muaj zog tig maj mam thiab nrog lub suab "humming", thiab cov ncej vibrates.Yog tias qhov ntsuas tam sim no ntawm ib theem yog xoom, thiab qhov tam sim no ntawm ob theem zoo heev tshaj qhov ntsuas tam sim no, nws txhais tau tias nws yog ob-theem ua haujlwm.Yog vim li cas yog vim li cas ib theem ntawm lub Circuit Court los yog lub hwj chim mov yog qhib los yog ib theem ntawm lub cev muaj zog winding yog qhib.
Thaum ib theem ntawm lub tshuab me me qhib, nws tuaj yeem kuaj xyuas nrog lub megohmmeter, multimeter lossis lub teeb tsev kawm ntawv.Thaum kuaj xyuas lub cev muaj zog nrog lub hnub qub lossis delta kev sib txuas, cov pob qij txha ntawm peb-theem windings yuav tsum tau disassembled, thiab txhua theem yuav tsum tau ntsuas rau qhib Circuit Court.Feem ntau ntawm cov windings ntawm nruab nrab muaj peev xwm motors siv ntau cov xov hlau thiab txuas nrog nyob rau tib lub sijhawm nyob ib ncig ntawm ntau ceg.Nws yog qhov nyuaj dua los xyuas seb puas muaj ob peb cov xov hlau tawg lossis cov ceg sib txuas tsis sib txuas.Txoj kev sib npaug peb-theem tam sim no thiab txoj kev tiv thaiv feem ntau yog siv.Feem ntau, thaum qhov sib txawv ntawm peb-theem tam sim no (lossis tsis kam) qhov tseem ceeb yog ntau dua 5%, theem nrog me me tam sim no (lossis loj tsis kam) yog qhov qhib Circuit Court theem.
Kev xyaum tau ua pov thawj tias qhov qhib-circuit txhaum ntawm lub cev muaj zog feem ntau tshwm sim thaum kawg ntawm winding, sib koom ua ke lossis cov hlau lead.
2. Lub fuse yog tshuab los yog lub thermal relay raug txiav thaum pib
1. Cov kauj ruam daws teeb meem.Xyuas seb lub peev xwm fuse puas tsim nyog, yog tias nws tsawg dhau, hloov nws nrog qhov tsim nyog thiab sim dua.Yog hais tias lub fuse txuas ntxiv tshuab, xyuas seb txoj siv txoj hlua tsav yog nruj dhau los yog lub nra hnyav dhau, seb puas muaj qhov luv luv hauv Circuit Court, thiab seb lub cev muaj zog nws tus kheej luv luv lossis hauv av.
2. Kev kuaj xyuas qhov txhaum hauv av.Siv lub megohmmeter los ntsuas qhov rwb thaiv tsev ntawm lub cev muaj zog winding rau hauv av.Thaum lub rwb thaiv tsev tiv thaiv qis dua 0.2MΩ, nws txhais tau hais tias lub winding yog ntub dej thiab yuav tsum tau qhuav.Yog tias qhov tsis kam yog xoom lossis lub teeb calibration yog ze rau qhov ci ci, cov theem yog grounded.Winding grounding feem ntau tshwm sim ntawm lub qhov hluav taws xob ntawm lub cev muaj zog, lub qhov nkag ntawm lub hwj chim kab lossis qhov txuas txuas ntxiv winding.Rau qhov kawg, yog tias nws pom tias qhov txhaum hauv av tsis loj heev, cov ntaub ntawv xyoob lossis cov ntaub ntawv insulating tuaj yeem muab tso rau ntawm stator core thiab winding.Tom qab paub meej tias tsis muaj av, nws tuaj yeem muab qhwv, pleev xim rau cov xim insulating thiab qhuav, thiab siv txuas ntxiv mus tom qab dhau qhov kev tshuaj ntsuam xyuas.
3. Kev tshuaj xyuas txoj kev winding short-circuit txhaum.Siv lub megohmmeter lossis multimeter los ntsuas qhov rwb thaiv tsev ntawm ob theem ntawm cov kab sib txuas.Yog tias nws txawm nyob ze rau xoom hauv qab 0.2Mf, nws txhais tau tias nws yog luv luv ntawm cov theem.Ntsuas qhov tam sim no ntawm peb lub windings feem, theem nrog qhov loj tshaj plaws tam sim no yog lub luv luv-circuit theem, thiab lub short-circuit detector kuj siv tau los xyuas cov interphase thiab inter-tig luv circuits ntawm windings.
4. Txoj kev txiav txim ntawm stator winding taub hau thiab tus Tsov tus tw.Thaum kho thiab kuaj xyuas lub cev muaj zog, nws yuav tsum tau rov ntsuas lub taub hau thiab tus Tsov tus tw ntawm stator winding ntawm lub cev muaj zog thaum lub qhov hluav taws xob disassembled thiab tsis nco qab tias yuav tsum tau sau los yog daim ntawv qub ploj.Feem ntau, cov txheej txheem tshuaj xyuas qhov seem ntawm cov hlau nplaum, cov txheej txheem kev tshuaj xyuas induction, cov txheej txheem diode qhia thiab cov kev txheeb xyuas ncaj qha ntawm txoj kab hloov yuav siv tau.Thawj ob peb txoj hauv kev txhua yam yuav tsum muaj qee yam cuab yeej, thiab tus ntsuas yuav tsum muaj qee qhov kev ua tau zoo.Txoj cai tswj xyuas ncaj qha ntawm kev hloov lub taub hau xov yog qhov yooj yim, thiab nws muaj kev nyab xeeb, txhim khu kev qha thiab intuitive.Siv lub ohm thaiv ntawm lub multimeter los ntsuas qhov twg ob lub xov hlau xaus yog ib theem, thiab tom qab ntawd arbitrarily kos lub taub hau thiab tus Tsov tus tw ntawm stator winding.Peb lub taub hau (los yog peb lub taub hau) ntawm tus lej cim tau txuas nrog lub voj voog raws li, thiab peb lub taub hau ntxiv (los yog peb lub taub hau) txuas ua ke.Pib lub cev muaj zog tsis muaj load.Yog tias qhov pib qeeb heev thiab lub suab nrov nrov, nws txhais tau hais tias lub taub hau thiab tus Tsov tus tw ntawm ib theem winding yog thim rov qab.Lub sijhawm no, lub hwj chim yuav tsum raug txiav tawm tam sim ntawd, txoj hauj lwm ntawm qhov txuas ntawm ib qho ntawm cov theem yuav tsum tau thim rov qab, thiab tom qab ntawd lub hwj chim yuav tsum tau qhib.Yog tias nws tseem zoo li qub, nws txhais tau hais tias lub sijhawm hloov pauv tsis thim rov qab.Rov qab lub taub hau thiab tus Tsov tus tw ntawm theem no, thiab hloov lwm yam ob theem nyob rau hauv lem nyob rau hauv tib txoj kev kom txog thaum lub suab pib ntawm lub cev muaj zog yog ib txwm.Txoj kev no yog qhov yooj yim, tab sis nws yuav tsum tsuas yog siv rau ntawm cov motors me thiab nruab nrab uas tso cai rau kev pib ncaj qha.Txoj kev no tsis tuaj yeem siv rau cov motors nrog lub peev xwm loj uas tsis tso cai rau kev pib ncaj qha.
