Cov khoom sib dhos ntawm lub tshuab hluav taws xob yog xav tau los hloov hluav taws xob mus rau armature windings. Txij li thaum lub armature tsim ib qho kev txav txav thaum lub sijhawm ua haujlwm, kev sib kis tau ua los ntawm kev sib cuag tshwj xeeb. Txhawm rau npaj kev txav mus los hauv txhua lub tsev thiab cov tshuab ua haujlwm, tsis siv cov phaj hlau. Qhov no yog vim muaj kev kub ceev, ntawm qhov kev sib txhuam ntawm cov hlau-rau-hlau yuav ua rau cov cua sov ntxiv ntawm qhov chaw ua hauj lwm thiab cov khoom tawg sai sai. Yog li ntawd, graphite los yog thee raug xaiv raws li kev sib cuag. Nws tau lub npe - hluav taws xob txhuam.
txhuam txhuam
Sliding type contact, tsim los muab thiab tso tawm hluav taws xob ntawm cov khoom siv lossis lub nplhaib sib txuas ntawm txhua hom hluav taws xob tshuab (lub tshuab hluav taws xob thiab cov tshuab hluav taws xob), tau hu ua hluav taws xob txhuam.
txhuam lub cev muaj zog yog tsim los nrog thiab tsis muaj hlau conductors. Cov hlau yog tsau nyob rau hauv txhuam los ntawm flaring, nias los yog los ntawm soldering. Txhuam tam sim no ua rau muaj cov npe hauv qab no:
- MPShch -yam tshwj xeeb ntawm cov hlau tso tseg, ua los ntawm tooj liab hlau;
- PShch - hloov tau hom tooj liab hlau braid;
- PShchS - universal xaim nrog nce flexibility.
Cov lus qhia hu tau rau ntawm cov hlau lead. Nrog kev pab los ntawm lawv, cov hlau yog tsau nrog ib tug txhuam tuav bolt. Cov lus qhia yog diav rawg, chij, ob chav thiab phaj hom.
Tim txhuam hniav
Muaj ntau chav kawm txhuam hniav uas ua rau muaj kev hloov pauv txawv:
- YGraphite txhuam. Lawv yog tsim los ntawm lub hauv paus ntawm graphite nrog ntxiv ntawm ib tug muab tub lim nyob rau hauv daim ntawv ntawm soot thiab lwm yam tshuaj. Txhuam yog npaj rau lub teeb commutation nyob rau hauv generators thiab cav. EG61A thiab G20 qib yog tsim.
- Carbon-graphite hom. Txhuam ntawm lub zog qis rau cov khoom siv me me. Qib G21, G22.
- Electrographite yam. Txhuam ntawm cov neeg kho tshuab muaj zog, saturated nrog carbon. Ua kev hloov ntawm nruab nrab complexity. Nrog siab tam sim no loads. Muaj hom EG2A, EG74, EG14, EG4, EG841.
- Hlau-graphite hom (tooj liab-graphite txhuam rau hluav taws xob motors). Lub ntsiab ntawm cov txhuam hniav yog tooj liab, tin thiab graphite hmoov. Lawv tuaj nrog txawv fillers. Cov txhuam hniav yog qhov ruaj khov thiab tsis tso cai rau cov pa roj thiab cov kua dej dhau mus. Muaj feem xyuam rau hauv high thiab medium complexity switching tej yam kev mob. Xyuas kom muaj kev ua haujlwm ntawm cov tshuab hluav taws xob tsis tshua muaj hluav taws xob. Cov cim muaj MG, MGS, MGS 5, MGS 20, MGS 51, MGSOA, MGSO,MGSO1M, M1A, M1.
Cov lus piav qhia txhuam yog siv tau rau hauv kev lag luam, txhuam ntawm G33MI, G33, G30, G31 hom yog tsim rau cov khoom siv hauv tsev.
Txhuam kev xaiv xaiv
Qhov tseem ceeb tshaj plaws thaum xaiv cov txhuam hniav yog kom paub qhov tsis zoo ntawm txhuam txhuam. Ntxiv nrog rau qhov ntev geometric, tus txhuam hniav tshiab yuav tsum ua kom haum rau qib ntawm graphite, hom thiab hla ntu ntawm cov hlau. Nws tsis yog yuav tsum tau coj tib lub hom raws li tus thawj, tab sis lub hardness ntawm lub cev muaj zog txhuam thiab cov kev khiav hauj lwm hom yuav tsum phim. Lub thickness ntawm cov hlau yuav tsum tsis txhob tsawg tshaj li qhov qub, thiab qhov yooj yuav tsum sib phim. Qhov yuam kev tseem ceeb thaum xaiv tus txhuam hniav:
- Nruab qhov sib cuag graphite qhov chaw uas siv cov softer. Qhov tshwm sim tuaj yeem hnav sai ntawm manifold.
- Kev teeb tsa "universal" txhuam txhua qhov chaw. Ua li no tuaj yeem cuam tshuam kev ua haujlwm ntawm lub cuab yeej.
- Kev taw qhia thaum yuav txhuam hniav ntawm qhov cim ntawm graphite ntawm ib sab ntawm lub tshuab qub txhuam. Graphite marking tsis yog hu rau parameter cim!
Vim li cas txhuam hniav
Lub ci ntsa iab ntawm txhuam zawv zawg raws tus neeg sau khoom yog ntuj, vim tias thaum lub sijhawm hloov ntawm ib lub lamella mus rau lwm qhov, qhov arc microdischarge tshwm sim. Nrog rau kev ua haujlwm zoo ntawm lub cav, kev pabcuam thiab kev ua raws li tag nrho cov ntsiab lus, nws tsis tshua pom qhov muag. Tab sis yog tias txhuam ntawm lub tshuab hluav taws xob muaj zog, qhov laj thawj qhia tau tias muaj kev ua haujlwm tsis zoo. Tsis quav ntsej cov txheej txheem no yog fraught nrog tsis ua hauj lwmanchors.
Qhov laj thawj vim li cas txhuam hniav yog raws li hauv qab no:
- Tsim cov hmoov av los yog av ntawm lub manifold. Nws yog qhov ua tau tias thaum lub sijhawm ua haujlwm ntev ntawm lub cav yam tsis muaj kev saib xyuas, ib zaj duab xis nyias ntawm soot tau tsim ntawm cov neeg sib cuag. Nws muaj zog tiv thaiv, uas ua rau sparking. Koj tuaj yeem txhim kho qhov teeb meem los ntawm kev xuab zeb commutator nrog xoom-grit sandpaper (nyob rau hauv cov kev taw qhia uas txhuam rotate).
- Kaw cov neeg nyob ib puag ncig nrog cov hmoov av graphite lossis hmoov tooj liab zoo. Nyob rau hauv cov ntaub ntawv no, tam sim no nce nyob rau hauv circuits, uas ua rau muaj zog sparking. Jumpers yuav tsum tau ua tib zoo tshem tawm nrog cov khoom ntse.
- Kev xaiv tsis raug ntawm txhuam tsis raug. Raws li qhov tshwm sim ntawm kev sib cuag tsis sib haum, kuj tseem yuav muaj cov pob zeb ntawm cov khoom siv. Graphite txhuam yuav tsum tau hloov raws li cov ntaub ntawv cav.
- Brush production.
- Interturn luv Circuit Court hauv armature windings. Xyuas armature thiab hloov yog tias muaj teeb meem.
Hloov txhuam lub cev muaj zog
Nws yog qhov yuav tsum tau hloov cov txhuam hniav thaum tsawg kawg yog ib feem peb ntawm cov haujlwm ua haujlwm, thiab ua raws li cov cai:
- Xaiv txhuam hniav uas haum rau qhov tsis ua dhau los.
- Ua kom pom qhov muag ntawm tus neeg sau thiab ntxuav nws yog tias tsim nyog.
- Yog tias qhov chaw ua haujlwm ntawm cov txhuam hniav muaj bevel, tsis txhob cuam tshuam nws qhov chaw.
- Muab lub sijhawm txhuam hniav rau ceg tawv, khiav lub cev tsis muaj zog, thiab tshem tawm ceg tawvplua plav los ntawm tus sau.
Zoo kawg
Ntxiv rau tag nrho cov kev ntsuas saum toj no rau kev saib xyuas cov txhuam hniav, kuj tseem muaj cov roj nplua nyeem tshwj xeeb rau cov khoom sib dhos. Lawv txo cov neeg kho tshuab thauj khoom ntawm kev sib cuag thiab tiv thaiv kev tsim cov deposits.
