Kuzindikira zolakwika ndi kukonza makina oziziritsira injini yamagalimoto (二)
2021-08-11
Imawira ndikusanduka yachibadwa pokhapokha atapanga madzi ozizira. Analysis ndi matenda:
(1) Pamene injini ikuwotcha mwadzidzidzi poyendetsa galimoto, choyamba tcherani khutu ku mphamvu ya ammeter. Ngati ammeter sikuwonetsa kuthamangitsa powonjezera phokoso, ndipo singano ya geji imangotulutsidwa ndi 3 ~ 5A Kugwedezeka kwapang'onopang'ono kubwerera ku "0" kumasonyeza kuti lamba wa fani wathyoka. Ngati ammeter ikuwonetsa kuthamangitsa, zimitsani injini ndikukhudza radiator ndi injini pamanja. Ngati kutentha kwa injini kuli kwakukulu kwambiri ndipo kutentha kwa radiator kuli kochepa, kumasonyeza kuti shaft ya madzi ndi chopondera ndi yotayirira, kusokoneza kayendedwe ka madzi ozizira; Ngati kusiyana kwa kutentha pakati pa injini ndi rediyeta sikuli kwakukulu, fufuzani ngati pali kutaya kwakukulu kwamadzi muzitsulo zozizira. Pambuyo pozindikira, kutentha kwa injini ndikokwera kwambiri ndipo kutentha kwa radiator kumakhala kochepa kwambiri, ndipo pampu yamadzi imakhala ndi mavuto;
(2) Kutentha kwa madzi ozizira kumakwera mofulumira poyambira koyamba, zomwe zimapangitsa kuti madzi ozizira awira. Vavu yaikulu ya multi-system thermostat imagwa ndipo imakankhidwa modutsa mupope yolowera madzi ya radiator, yomwe imalepheretsa kuyenda kwakukulu kwa madzi ozizira ndikuwonjezera mofulumira kupanikizika mu dongosolo lozizira. Kupanikizika kwamkati kukafika pamlingo wina, valavu yayikulu yokhazikika idzakakamiza mwadzidzidzi kusintha momwe imayendera ndikulumikiza njira yayikulu yozungulira madzi, Panthawiyi, madzi otentha amathamangitsa kapu ya radiator. Ngati madzi ozizira nthawi zonse akuwira pamene mukuyendetsa galimoto, yimitsani injini nthawi yomweyo kuti injiniyo ikhale yothamanga kwambiri mpaka kutentha kwa madzi kuli bwino, ndiyeno muzitseke kuti muwunikenso. Sizololedwa kusakaniza madzi kuti azizirike, kuti ateteze ming'alu ya zigawo zofunikira chifukwa cha kupsinjika kwamkati komwe kumachitika chifukwa cha kusiyana kwakukulu kwa kutentha. Ngati silinda gasket kuwotchedwa, nthawi zina thanki madzi pakamwa akhoza kusefukira ndi kutulutsa thovu, kusonyeza kuwira kwa madzi ozizira. Izi zili choncho makamaka chifukwa gasket ya silinda yatenthedwa kapena mutu wa silinda ndi cylinder liner zimakhala ndi ming'alu, zomwe zimapangitsa kuti mpweya wothamanga kwambiri ulowe mu jekete lamadzi ndikutulutsa thovu loopsa. Ngati mng'alu wa silinda gasket kapena mutu wa silinda umalumikizidwa ndi dera lopaka mafuta, madontho amafuta amawonekeranso mu thanki yamadzi. Njira yowunikira gasi wothamanga kwambiri mu silinda yolowera munjira yozizira: chotsani lamba wakufanizira ndikuyimitsa mpope wamadzi. Pamene choyambira chikuthamanga pansi pa liwiro laling'ono, ming'oma idzawoneka pamtunda wa madzi a thanki yamadzi ndipo phokoso la "grunt, grunt" lidzamveka, lomwe likutuluka pang'ono; Ngati mpope wamadzi sunayimitsidwe, ming'oma imatha kuwoneka bwino ndipo phokoso la "grunt, grunt" limatha kumveka, lomwe ndilo kuphulika kwakukulu kwa mpweya; Chivundikiro cha thanki lamadzi chidzaphulika ngati mphika wowira, womwe ndi mpweya wotuluka kwambiri. Ngati madzi ozizira alowetsedwa mu silinda, nthunzi imatulutsidwa mu chitoliro chopopera panthawi yoyambira ndipo utsi woyera umatuluka pakugwira ntchito. Palibe chodabwitsa chotero pambuyo pozindikira.

Zotsatira zoyesa: pali vuto ndi mpope wamadzi. kukonzanso:
Kuchotsa kwa sikelo: gwiritsani ntchito zomwe zimachitika pakati pa asidi kapena alkali ndi sikelo kuti mupange zinthu zatsopano zosungunuka m'madzi kuti muchotse sikelo. Pakuyeretsa, ndi bwino kutengera yaying'ono kufalitsidwa njira: choyamba kuyeretsa ndi acidic yankho, ndiyeno muzimutsuka ndi zamchere njira neutralization. Pakutsuka, chotsitsacho chimazungulira mu tanki yamadzi pamagetsi ena (nthawi zambiri 0.1MPa) kwa 5min Mukatsuka.
Kukonza ma radiator: Kuzindikira zolakwika za radiator ndikotayikira. Pali njira ziwiri zokonzera kutayikira kwa radiator; Njira yokonza welding ndi njira yolumikizira. Konzani galimoto ndi ma radiator plugging agent (i.e. plugging njira). Musanayambe kukonza, yeretsani radiator ndikuwonjezera 1: 2 Injini iyenera kugwiritsidwa ntchito pafupifupi 80 ℃ kwa 5min Pambuyo, tsitsani madzi amchere, tsukani ndi madzi oyera, yambani injini, ndikukhetsa madzi pamene galimoto yatenthedwa mpaka 80. ℃. Kenako chotsani chotenthetsera ndikusintha plugging 1:20 Onjezani madzi molingana ndi, yambani injini, kwezani kutentha kwa madzi mpaka 80 ~ 85 ℃ ndikusunga kwa 1.0min. Sungani madzi ozizira omwe ali ndi plugging mu makina ozizira kwa 3 ~ 4 maola O, Mulungu wanga. Radiator yokonzedwayo idapambana mayeso a kutayikira ndipo idaperekedwa popanda kutayikira.
Kusamalira mpope wamadzi: Musanakonzekere mpope wamadzi, chotsani mpope wamadzi mu injini ndikuyichotsa. Mukachotsa mpope wamadzi, choyamba yatsani chosinthira chamadzi cha radiator ndi injini, ikani choziziritsa kukhosi mu chidebe choyera, chotsani ma bolts a pampu yamadzi ndi ma bolts pampando wa pulley, chotsani cholowera madzi ndikutulutsa. payipi, ndikuchotsa chowotcha ndi zida zina zofunika ndikuyendetsa ma pulleys. Chotsani ndodo yosinthira ndi bawuti ya lamba woyendetsa, ndiyeno chotsani mpope wamadzi ndi gasket yosindikiza. Mukamasula mpope wamadzi, choyamba masulani mabawuti ophimba pampu, chotsani chivundikiro cha mpope ndikusindikiza gasket. Kenako gwetsani chokokera pansi chokokera; Kenako ikani mpope wamadzi m'madzi kapena mafuta ndikuwotcha mpaka 75 ~ 85 ℃, chotsani pompano yamadzi, chosindikizira chamadzi ndi msonkhano wopopera madzi ndi mpope wamadzi wokhala ndi disassembler ndikusindikiza, ndipo pomaliza akanikizire pampu yamadzi. . Zinthu zowunikira mbali za mpope wamadzi zimaphatikizansopo: (1) ngati pampu ndi mpando wapampu zatha ndikuwonongeka, ndikuzisintha ngati kuli kofunikira. Ulusi wakumapeto kwa shaft wawonongeka (3) Kaya tsamba la chopondera lathyoka komanso ngati dzenje latsinde lavala kwambiri. seal ndi bakelite pad kuposa malire a utumiki, idzasinthidwa ndi magawo atsopano (5) Mukayang'ana kuvala kwa shaft, yesani kupotoza ndi chizindikiro choyimba. Ngati ipitilira 0.1mm, m'malo mwake lowetsani chatsopano. Samalani mfundo zotsatirazi pokonza mpope wa madzi: (1) ngati chisindikizo chamadzi chatha ndipo chaphwanyidwa, chikhoza kuphwanyidwa ndi nsalu ya emery. Ngati yavala kwambiri, iyenera kusinthidwa; Ngati pampando wosindikizira pamadzi pamakhala zokopa, zitha kukonzedwa ndi chowongolera ndege kapena pa lathe (2) Kukonza kuwotcherera kumaloledwa pamene mpope ili ndi kuwonongeka kotsatiraku: kutalika ndi 30mm Pansipa, palibe mng'alu womwe umapitilira mpaka. dzenje loberekera; Flange yophatikizidwa ndi mutu wa silinda yawonongeka; Bowo la mpando wosindikizira mafuta lawonongeka (3) Kupindika kwa tsinde la mpope sikuyenera kupitirira 0.03mm, mwinamwake kudzasinthidwa kapena kukonzedwa ndi kuzizira kozizira (4) Bwezerani tsamba lowonongeka. Kukhazikitsa ndi kukhazikitsa pampu yamadzi.
Zotsatira zake ndizosiyananso za disassembly ndi disassembly. Pa msonkhano, tcherani khutu ku luso lapadera pakati pa zigawo zokwerera. Poika msonkhano wa mpope wamadzi pa injini, samalani ndi izi: (1) sinthani ndi gasket yatsopano panthawi yoikapo (2) Yang'anani ndikusintha kulimba kwa lamba. Nthawi zambiri, 100N imagwiritsidwa ntchito pakati pa lamba Pamene kukakamiza koyenera kukanikizira pansi lamba, kupatukako kumakhala 8 ~ 12mm. Ngati sichikukwaniritsa zofunikira, sinthani kulimba kwake (3) Mukayika mpope wamadzi, gwirizanitsani mipope yofewa yamadzi ozizira, onjezerani madzi ozizira, yambitsani injini, ndikuyang'ana ntchito ya mpope wamadzi ndi madzi ozizira. kuzirala kwa kutayikira.
Kupyolera mu kukonza pamwambapa, kutentha kwa injini yamagalimoto kumabwerera mwakale.
