Txhua lub tsheb niaj hnub muaj lub tshuab hluav taws xob uas muab qhov pib ntawm lub zog hluav taws xob.Ib qho tseem ceeb ntawm qhov pib yog cov txhuam txhuam uas muab hluav taws xob tam sim no rau lub armature.Nyeem txog kev pib txhuam hniav, lawv lub hom phiaj thiab kev tsim, nrog rau kev kuaj mob thiab kev hloov hauv cov lus qhia.
Lub hom phiaj thiab lub luag haujlwm ntawm txhuam hauv lub tshuab hluav taws xob
Hauv cov tsheb niaj hnub no feem ntau nruab nrog lub tshuab hluav taws xob sab hauv, kev ua haujlwm ntawm kev pib lub zog hluav taws xob yog daws nrog lub tshuab hluav taws xob.Tshaj li ib nrab xyoo dhau los, cov pib tsis tau hloov pauv tseem ceeb: lub hauv paus ntawm tus qauv tsim yog compact thiab yooj yim DC lub cev muaj zog, uas yog supplemented los ntawm ib tug relay thiab ib tug tsav mechanism.Lub tshuab hluav taws xob pib muaj peb lub ntsiab lus tseem ceeb:
- Lub cev sib dhos nrog stator;
-Anchor;
- Txhuam sib dhos.
Lub stator yog qhov ruaj khov ntawm lub tshuab hluav taws xob.Feem ntau siv yog electromagnetic stators, nyob rau hauv uas lub magnetic teb yog tsim los ntawm teb windings.Tab sis koj tuaj yeem pom cov pib nrog stators raws li cov hlau nplaum ruaj khov.Lub armature yog qhov txav ntawm lub tshuab hluav taws xob, nws muaj cov windings (nrog cov lus qhia ncej), cov khoom sib dhos thiab cov khoom tsav (cov iav).Kev sib hloov ntawm lub armature yog muab los ntawm kev sib cuam tshuam ntawm magnetic teb tsim nyob ib ncig ntawm lub armature thiab stator windings thaum muaj hluav taws xob tam sim no siv rau lawv.
Cov txhuam hniav sib dhos yog lub tshuab hluav taws xob sib dhos uas muab zawv zawg sib cuag nrog cov khoom txav txav tau.Cov txhuam txhuam txhuam muaj ntau qhov tseem ceeb - txhuam thiab txhuam txhuam uas tuav cov txhuam hniav hauv txoj haujlwm.Cov txhuam hniav yog nias tawm tsam lub armature collector los ua ke (nws muaj ib tug xov tooj ntawm tooj liab daim hlau uas yog cov kev sib cuag ntawm armature windings), uas xyuas kom meej ib tug tas li ntawm tam sim no mus rau lub armature windings thaum nws tig.
Cov txhuam txhuam pib yog qhov tseem ceeb thiab cov khoom tseem ceeb uas yuav tsum tau piav qhia kom ntxaws ntxiv.
Hom thiab tsim ntawm cov hniav pib
Raws li txoj cai, tag nrho cov txhuam pib pib yog qhov zoo ib yam.Ib qho txhuam txhuam muaj ob qhov tseem ceeb:
- Txhuam molded los ntawm cov khoom muag muag;
- Saj zawg zog tus neeg xyuas pib (nrog lossis tsis muaj lub davhlau ya nyob twg) los muab tam sim no.
Cov txhuam hniav yog ib qho parallelepiped molded los ntawm cov khoom siv tshwj xeeb raws li graphite.Tam sim no, pib txhuam hniav yog ua los ntawm ob yam khoom tseem ceeb:
- Electrographite (EG) lossis graphite dag.Cov khoom tau los ntawm kev nias thiab ci los ntawm coke lossis lwm yam khoom siv hluav taws xob raws li carbon thiab hydrocarbon binder;
- Composites raws li graphite thiab hlau hmoov.Feem ntau siv tooj liab-graphite txhuam yog nias los ntawm graphite thiab tooj liab hmoov.
Feem ntau siv tooj liab-graphite txhuam.Vim qhov suav nrog tooj liab, cov txhuam hniav zoo li no muaj hluav taws xob tsawg dua thiab tiv taus hnav ntau dua.Cov txhuam hniav zoo li no muaj ob peb qhov tsis zoo, qhov tseem ceeb yog qhov ua kom muaj zog ntxiv, uas ua rau muaj zog hnav ntawm armature manifold.Txawm li cas los xij, kev khiav hauj lwm lub voj voog ntawm lub oob khab feem ntau yog luv (los ntawm ob peb kaum vib nas this mus rau ob peb feeb hauv ib hnub), yog li kev hnav ntawm lub manifold qeeb.
Ib lossis ob qhov hloov pauv hloov pauv ntawm qhov loj hla ntu yog rigidly tsau hauv lub cev ntawm txhuam.Conductors yog tooj liab, stranded, woven los ntawm ob peb nyias nyob ntawm tej (uas muab tau yooj yim).Ntawm cov txhuam hniav rau cov pib qis qis, tsuas yog ib tus neeg xyuas pib feem ntau yog siv, ntawm cov txhuam hniav rau cov pib lub zog siab, ob tus neeg xyuas pib tau tsau rau ntawm qhov sib txawv ntawm cov txhuam hniav (rau cov khoom siv tam sim no).Kev teeb tsa ntawm tus neeg xyuas pib feem ntau yog siv lub tes tsho hlau (piston).Tus neeg xyuas pib tuaj yeem yog liab qab lossis insulated - nws tag nrho yog nyob ntawm tus tsim ntawm ib qho kev pib.Lub davhlau ya nyob twg tuaj yeem nyob ntawm qhov kawg ntawm tus neeg xyuas pib kom yooj yim ntawm kev teeb tsa.Cov conductors yuav tsum tau hloov tau, uas tso cai rau tus txhuam kom hloov txoj hauj lwm thaum hnav thiab thaum pib ua haujlwm, tsis txhob poob kev sib cuag nrog lub manifold.
Ob peb txhuam yog siv nyob rau hauv lub starter, feem ntau lawv cov naj npawb yog 4, 6 los yog 8. Nyob rau hauv cov ntaub ntawv no, ib nrab ntawm cov txhuam yog txuas nrog "hauv av", thiab ib nrab rau stator windings.Qhov kev sib txuas no ua kom ntseeg tau tias thaum lub oob khab relay qhib, tam sim no yog ib txhij siv rau stator windings thiab armature windings.
Cov txhuam hniav yog taw qhia nyob rau hauv tus txhuam hniav nyob rau hauv xws li ib txoj kev uas txhua lub sij hawm ntawm lub sij hawm tam sim no yog siv rau tej yam armature windings.Txhua txhuam yog nias tawm tsam lub manifold los ntawm lub caij nplooj ntoos hlav.Cov txhuam hniav, ua ke nrog cov txhuam hniav, yog ib chav tsev sib cais, uas, yog tias tsim nyog los kho lossis hloov cov txhuam hniav, tuaj yeem rhuav tshem thiab yooj yim ntsia hauv qhov chaw.
Feem ntau, pib txhuam hniav yog qhov yooj yim heev, yog li lawv txhim khu kev qha thiab ruaj khov.Txawm li cas los xij, lawv kuj xav tau kev saib xyuas thiab kho ib ntus.
Cov teeb meem ntawm kev kuaj mob thiab kho cov txhuam pib
Thaum lub sijhawm ua haujlwm, cov txhuam pib pib raug coj mus tas li thiab cov khoom siv hluav taws xob tseem ceeb (thaum lub sijhawm pib lub cav, qhov tam sim no ntawm 100 txog 1000 lossis ntau dua amperes ntws los ntawm cov txhuam), yog li thaum lub sijhawm lawv txo qhov loj thiab tawg.Qhov no tuaj yeem ua rau poob ntawm kev sib cuag nrog tus neeg sau, uas txhais tau hais tias kev ua haujlwm tsis zoo ntawm tag nrho cov pib.Yog hais tias lub oob khab pib ua hauj lwm tsis zoo nyob rau lub sij hawm, tsis muab qhov tsim nyog angular tshaj tawm ntawm kev sib hloov ntawm lub crankshaft los yog tsis tig rau tag nrho, ces koj yuav tsum xyuas nws relay, tus mob ntawm cov hluav taws xob tiv tauj thiab, thaum kawg, txhuam.Yog hais tias txhua yam nyob rau hauv kev txiav txim nrog lub relay thiab kev sib cuag, thiab lub starter tsis ua hauj lwm zoo txawm tias thaum txuas nrog lub roj teeb, bypassing lub relay, ces qhov teeb meem yuav tsum tau nrhiav nyob rau hauv lub txhuam.
Txhawm rau kuaj xyuas thiab hloov cov txhuam hniav, lub tshuab pib yuav tsum tau muab tshem tawm thiab tshem tawm, feem ntau, disassembly yog ua raws li hauv qab no:
- Unscrew lub bolts tuav lub nraub qaum ntawm lub oob khab;
- Tshem lub hau;
- Tshem tag nrho cov ntsaws ruaj ruaj thiab clamps (feem ntau muaj ob lub O-rings, ib lub clamp thiab lub gasket nyob rau hauv lub oob khab);
- Ua tib zoo tshem tus txhuam tuav los ntawm armature manifold.Nyob rau hauv cov ntaub ntawv no, cov txhuam hniav yuav raug thawb tawm los ntawm springs, tab sis tsis muaj dab tsi txaus ntshai yuav tshwm sim, vim hais tias cov khoom yog tuav los ntawm saj zawg zog conductors.
Tam sim no koj yuav tsum tau ua kom pom qhov kev tshuaj xyuas ntawm cov txhuam hniav, ntsuas qhov ntsuas ntawm kev hnav thiab kev ncaj ncees.Yog tias cov txhuam hniav muaj qhov hnav ntau dhau (muaj qhov ntev luv dua li qhov pom zoo los ntawm cov chaw tsim khoom), tawg, kinks lossis lwm yam kev puas tsuaj, ces lawv yuav tsum tau hloov.Ntxiv mus, tag nrho cov txhuam txhuam hloov tam sim ntawd, vim tias cov txhuam hniav qub yuav sai sai thiab kev kho yuav tsum tau ua dua.
Dismantling ntawm txhuam yog nqa tawm nyob ntawm seb lawv hom fastening.Yog hais tias cov conductors tsuas yog soldered, ces koj yuav tsum tau siv ib tug soldering hlau.Yog hais tias muaj cov terminals ntawm cov conductors, ces dismantling thiab installation yog txo kom unscrewing / screwing nyob rau hauv screws los yog bolts.Kev txhim kho cov txhuam hniav tshiab yog ua tiav nyob rau hauv qhov kev txiav txim rov qab, thaum nws yog ib qho tsim nyog los saib xyuas kev ntseeg siab ntawm kev sib cuag hluav taws xob.
Tom qab hloov cov txhuam hniav, lub oob khab yog sib sau ua ke nyob rau hauv qhov kev txiav txim rov qab, thiab tag nrho chav tsev yog ntsia rau hauv nws qhov chaw tsis tu ncua.Cov txhuam hniav tshiab muaj qhov ua haujlwm tiaj tus, yog li lawv yuav "khiav-hauv" rau ob peb hnub, thaum lub sijhawm pib yuav tsum zam ntawm kev thauj khoom ntau ntxiv.Nyob rau hauv lub neej yav tom ntej, cov pib txhuam tsis tas yuav tsum muaj kev saib xyuas tshwj xeeb thiab tu.
