Qee lub sij hawm peb ntsib cov xwm txheej uas lub cev muaj zog ntawm qhov sib sib zog nqus dej twj tso kua mis tsis tig tom qab txuas lub zog, tab sis ua rau lub suab nrov nrov. Qhov no yog vim li cas? Cia peb txheeb xyuas ntau yam tshwm sim thiab qhia koj qee cov lus qhia los daws lawv.
1, Tsis muaj theem
Fault phenomenon:
Thaum lub cev muaj zog nrog Y-puab thaiv kev paub txog theem poob haujlwm, los ntawm sab saum toj, cov symmetrical stator core muaj peb qhov, piv txwv li ib theem, thiab cov ntawv rwb thaiv tsev yog qhov tseem ceeb. Tsis tas li ntawd, ob-theem rwb thaiv tsev ntawv undergoes deformation, melting, tawg, plhaub deformation, tawg, thiab hauv qab airbag ruptures.
Yog vim li cas rau malfunction:
1. Cov hlau yog cua sov thiab cov ntsia hlau yog xoob thaum txuas cov khoom siv hluav taws xob.
Yog tias ib theem twg ploj lawm nyob rau hauv Y-shaped winding, yuav tsis muaj tam sim no nyob rau hauv lub caij uas ploj lawm winding, thiab tam sim no nyob rau hauv lwm yam ob theem yuav loj dua.
Kev daws:
1. Nruab lub thawv tswj.
2. Siv cov khoom siv hluav taws xob tsim nyog, thiab DC tsis kam ntawm lub cable yuav tsum tsis pub dhau lub teb chaws tus qauv yam tsawg kawg nkaus.
2, Overheating (ntau dhau)
Fault phenomenon:
Ib-theem lub cev muaj zog overheats, ua rau lub ntsiab thiab pab windings hlawv tawm thaum pib. Yog tias qhov kev puas tsuaj me me, tag nrho stator rwb thaiv tsev txheej yuav yaj. Yog tias nws kub hnyiab heev, cov hlau enameled yuav yaj thiab tawg, lub plhaub yuav deform thiab puncture, thiab hauv qab airbag yuav tawg.
Yog vim li cas rau malfunction:
Qhov hluav taws xob siab dhau los yog qis dhau, cable ntev dhau lawm thiab DC tsis kam tshaj tus qauv, cable hla ntu me me dhau lawm, lub taub hau twj tso kua mis thiab kev teeb tsa ntws siab dhau lawm, dej tsis zoo, thiab cov ntsiab lus ntawm cov khoom tau dhau los ntawm tus qauv.
Kev daws:
1. Nruab ib daim ntawv qhia tshwj xeeb cua txias npog sab nraum lub submersible lub cev muaj zog los ua kom cov dej ntws nrawm nrawm ntawm lub cev muaj zog thiab tshem tawm cov cua sov sai dua.
2. Siv cov khoom siv hluav taws xob tsim nyog, thiab DC tsis kam ntawm lub cable yuav tsum tsis pub dhau lub teb chaws tus qauv yam tsawg kawg nkaus.
3, Kev ywg dej
Fault phenomenon:
Muaj cov dej stains ntawm qhov chaw ntawm lub cable, tab sis tsis muaj cov xov hlau tawg. Thaum siv multimeter los ntsuas, nws tau pom tias DC tsis kam yog qhov qub, tab sis thaum siv lub rooj sib tsoo los ntsuas qhov rwb thaiv tsev tiv thaiv, tus taw tes tig mus rau qhov kev taw qhia ntawm xoom lossis tsis zoo. Nyob rau lub sijhawm no, nws tau pom tias qee qhov ntawm lub cable tau hnav, thiab cov xov hlau thiab cables uas tawm ntawm lub cev muaj zog tau txuas tsis raug, nrog cov dej pom tseeb.
Yog vim li cas rau malfunction:
Feem ntau, nws yog tshwm sim los ntawm cov neeg kho tshuab ntsaws ruaj ruaj, vim tsis zoo ib puag ncig nyob rau hauv qee qhov chaw, lub plhaub corrodes thiab dej nkag mus, thaum nyob rau hauv qee qhov chaw, nws yog tshwm sim los ntawm cable hnav, dej to, thiab cable tsis zoo, ua rau dej nkag. Qee qhov xwm txheej yog tshwm sim los ntawm kev teeb tsa lub plhaub, kev teeb tsa airbag, kev teeb tsa lub taub hau, thiab cable to.
Kev daws:
1. Txhim kho qhov kev siv ib puag ncig los ntawm kev sib txuas kom raug lub cev muaj zog thiab cov cables.
2. Nws raug nquahu kom hloov lub cev muaj zog.
4, Sweeping Hall
Fault phenomenon:
Kev ntxuav ntawm lub cev muaj zog rotor yog tshwm sim los ntawm kev hnav ntau dhau ntawm lub cev muaj zog bearings. Nws tau pom tias qhov kub ntawm lub cev muaj zog tau nce, thiab lub cev muaj zog ua rau lub suab "buzzing". Tom qab disassembling lub cev muaj zog, ncig khawb tau tshwm sim ntawm lub rotor thiab stator vim hnav.
Yog vim li cas rau malfunction:
1: Lub cev muaj zog overheating ua rau me me bearing clearance thiab jamming.
2: Lub rotor dynamic ntsuas qhov tseeb tsis ua raws li qhov yuav tsum tau ua.
3: Tsis zoo ntawm bearings.
4: Ua los ntawm cov kab rotor tawg, kev teeb tsa tsis zoo ntawm cov kabmob, cov kabmob sab sauv thiab sab qis, thiab lwm yam.
5: Lub coaxiality ntawm lub stator, rotor, vaj tse, thiab sab sauv thiab sab bearings yog pluag, thiab dynamic tshuav nyiaj li cas ntawm lub rotor tsis tau raws li cov kev cai.
Kev daws:
1. Nws raug pom zoo kom hloov lub cev muaj zog.
2. Tom qab cheb lub tsev, cov kabmob kuj tuaj yeem hloov tau.
