Njinga maburashi: Mitundu ntchito, m'malo

Wokhometsa wa unit galimoto ayenera kupereka magetsi kwa armature kumulowetsa. Popeza nangula umabala makina zoyenda pa ntchito, kulanda ikuchitika kudzera kukhudzana wapadera. Kukonza kukhudzana makina m'banja ndi mafakitale injini zonse osagwiritsa ntchito mbale zitsulo. Ichi ndi chifukwa liwiro mkulu pa zimene mikangano ya chitsulo pa zitsulo adzatulutsa Kutentha zina padziko ntchito ndi kusala wokhometsa linanena bungwe. Choncho, graphite kapena makala anasankhidwa ngati kukhudzana ndi. Iye anapatsidwa dzina lakuti - ndi burashi magetsi.

maburashi galimoto

Contact kutsetsereka mtundu, oyesa mwachidule ndi zosangalatsa magetsi pa okhometsa kapena malo mphete za mitundu yonse ya makina magetsi (Motors ndi magudumu), wotchedwa zamagetsi.

Njinga maburashi zilipo ndi mawaya zitsulo, ndipo popanda iwo. Kuika mawaya kunyamula burashi ndi kuwonjezera, jacking kapena soldering. Tokovody burashi ndi zopangidwa amenewa:

• MPSCH - mtundu wapadera wa waya Shackleton zopangidwa waya mkuwa;
• PG - kusintha waya mtundu mkuwa waya kumanga;
• PGS - chilengedwe chingwe ndi kumatheka kusinthasintha.

Pa waya kutsogolera anapereka malangizo kukhudzana. Ndi iwo, chofukizira waya burashi atathana bawuti. Nsonga ndi forklift, mbendera, ndi mtundu awiri mbale.

mitundu ya maburashi

Pali magulu angapo a maburashi kuti akakomane ndi zikhalidwe zosiyana kusinthitsa:

• Graphite burashi. Amachita pa maziko a graphite wodzilemekeza ndi filler mu mawonekedwe a mwaye ndi zinthu zina. Burashi anafuna kusintha magudumu wofatsa ndi Motors. Marks ndi EG61A ndi G20.
• Kaboni graphite mtundu. Maburashi mphamvu otsika katundu ang'onoang'ono makina. Stamps r21, T22.
• Elektrografitnogo mtundu. Maburashi kuchuluka mphamvu mawotchi, zimalimbikitsa mpweya. Kuchita kusinthitsa mavuto sing'anga. Kupirira mkulu katundu panopa. Pali zopangidwa EG2A, EG74, EG14, EG4, EG841.
• Zitsulo-graphite mtundu (mednografitovye maburashi kwa Motors). Mbali yaikulu ya burashi ndi mkuwa, tini ndi graphite ufa. Awa ndi fillers osiyana. Maburashi ndi mphamvu yapamwamba, musalole mpweya ndi madzi sing'anga. Zothandiza zinthu mkulu ndi zolimbitsa Kuvuta kusintha. Onetsetsani ntchito kwa magudumu otsika-voteji. Masitampu ndi MG, EASC, 5 Sci, Sci 20, IGU 51 MGSOA, MGSO, MGSO1M, M1A, M1.

Anafotokoza burashi kulankhula ndi wofunika makampani, chifukwa zipangizo banja kutulutsa zizindikiro burashi G33MI, r33, -30, G31.

Posankha kukhudzana burashi

Chinthu chofunika kwambiri posankha mota maburashi ndi - kudziwa magawo anayamba maburashi. Kuwonjezera miyeso zojambula, ndi burashi watsopano ayenera kukhala chimodzimodzi graphite mtundu, mtundu ndi gawo mtanda wa waya. Sikuti kutenga mtundu mofanana pachiyambi, koma kuuma kwa burashi galimoto ndipo ikugwira ntchito modes ayenera kukhala yemweyo. The makulidwe a mawaya sayenera kakang'ono kuposa choyambirira, ndi kusinthasintha kwa zikugwirizana. zolakwa zofunika kusankha burashi kukhudzana:

• Khazikitsa zolimba graphite kulankhula pamene ntchito lililonse limatisokoneza. Zimenezi zikhoza kukhala avale mofulumira wokhometsa lapansi.
• Kuika "konsekonse" burashi kulikonse. Izi zikhoza kusokoneza ntchito chipangizo.
• The lathu pamene kugula graphite burashi pa zaka chizindikiro mbali burashi galimoto. Kulemba graphite - si chosonyeza magawo kukhudzana!

Chifukwa burashi kuthetheka

Sparking maburashi kutsetsereka pa wokhometsa ndi, mwachibadwa, chifukwa mu nthawi ya kusintha kwa lamella wina ndi mzake ndi microdischarge Arc. Ndi uziyenda bwino za injini, Kutukula ndi kugwilizana zinthu zonse ndi mochenjera diso. Koma ngati wamphamvu mphanvu burashi galimoto, chifukwa likunena za mavuto kuntchito. Kunyalanyaza ndondomeko izi zikhoza kuwononga armature.

The zifukwa chifukwa cha zomwe inayambitsa burashi, zotsatirazi:

• Fouling kapena zoipa pa wokhometsa lapansi. Mwina pambuyo yaitali injini ntchito popanda kulankhula yokonza wokhometsa anapanga pa filimu zonyalazo varnish. Iwo ali kukana mkulu, zomwe zimabweretsa nsakali. Kodi vutolo mwa kuchitira wokhometsa ziro grit sandpaper (motsogozedwa kumene maburashi onsewo).
• Dera ojambula pafupi fumbi wokhometsa wa graphite chabwino kapena ufa mkuwa. Pankhaniyi, dera mafunde kuwonjezeka, imbaenda ku nsakali amphamvu. Mphutu kukhala molondola kuthetsa chinthu lakuthwa.
• Cholakwika kusankha magawo burashi. Chifukwa, kukhudzana kukana mismatch nawonso muyambe wokhometsa. Muyenera m'malo mpweya maburashi, zochokera injini ya zolembedwa luso.
• Development wa maburashi.
• Kumulowetsa dera lalifupi mu windings wa armature lapansi. Fufuzani ndi kutibwezera nangula mu nkhani kulephera.

M'malo galimoto maburashi ndi

Kusintha burashi n'kofunika pamene gawo zikugwira ntchito ya kumanzere ndi osachepera wachitatu, komanso kutsatira malamulo:

• Kukoma burashi lolingana magawo m'mbuyomu.
• Zithunzi anayendera posungira ndi oyera ngati n'koyenera.
• Ngati pamwamba ntchito ya burashi ali ndi chamfer, osati kusokonezedwa malo ake.
• Perekani mpata kwa akupera maburashi, kuphatikizapo galimoto popanda katundu, kenako akukuta kuchotsa fumbi kwa wokhometsa lapansi.

Pomaliza

Kuwonjezera zinthu izi zonse kusamalira maburashi, palinso ali wapadera mafuta wokhometsa unit. Iwo akhoza kuchepetsa nkhawa makina pa kukhudzana ndi kuteteza mapangidwe mwaye.
