Njengemishini yokwakha imigwaqo ephansi, ogandaganda bangonga izinto eziningi kanye nabasebenzi, basheshise ukwakhiwa komgwaqo, futhi banciphise ukuqhubeka kwephrojekthi.Emsebenzini wansuku zonke, ama-bulldozers angase abe nokungasebenzi kahle ngenxa yokungalungiswa kahle noma ukuguga kwemishini.Okulandelayo ukuhlaziya okuningiliziwe kwezimbangela zalokhu kwehluleka:
- Ugandaganda ngeke uqale: Ngemva kokusetshenziswa okuvamile, ngeke uqale futhi futhi akukho ntuthu.Isiqalo sisebenza ngokujwayelekile, futhi ekuqaleni kwahlulelwa ukuthi umjikelezo kawoyela unephutha.Lapho ngisebenzisa iphampu yezandla ukupompa uwoyela, ngathola ukuthi inani lamafutha ampontshwa lanele, kwakungekho moya ekugelezeni kwamafutha, futhi iphampu yezandla ingasebenza ngokushesha.Lokhu kubonisa ukuthi ukunikezwa kwamafutha kuyinto evamile, ulayini kawoyela awuvinjiwe, futhi akukho ukuvuza komoya.Uma kungumshini osanda kuthengwa, kungenzeka ukuthi i-fuel injection pump ingasebenzi kahle (i-lead seal ayivuliwe) incane kakhulu.Ekugcineni, lapho ngibona i-lever enqanyuliwe, ngathola ukuthi yayingekho esimweni esivamile.Ngemva kokuyiphendula ngesandla, yaqala ngokujwayelekile.Kunqunywe ukuthi iphutha liku-valve ye-solenoid.Ngemva kokufaka i-valve ye-solenoid, injini yasebenza ngokujwayelekile futhi iphutha laxazululwa.
- Ubunzima bokuqalisa i-bulldozer: Ngemva kokusetshenziswa okuvamile nokuvala, i-bulldozer iqala kabi futhi ayikhiphi intuthu eningi.Uma usebenzisa iphampu yezandla ukupompa uwoyela, inani lamafutha elipompayo alilikhulu, kodwa akukho moya ekugelezeni kwamafutha.Lapho iphampu eyenziwa ngesandla isebenza ngokushesha, kuzokwenziwa ivacuum enkulu, futhi ipiston yepompo likawoyela izozincela ngokuzenzakalelayo.Kwahlulelwa ukuthi akukho ukuvuza komoya emgqeni kawoyela, kodwa kubangelwa ukungcola okuvimbela umugqa wamafutha.Izizathu zokuvinjwa kolayini kawoyela yilezi:
①Udonga lwangaphakathi lwerabha lwepayipi likawoyela lungase luhlukane noma liwe, kubangele ukuvaleka kwentambo kawoyela.Njengoba umshini ungakaze usetshenziswe isikhathi eside, ithuba lokuguga lincane futhi lingakhishwa okwesikhashana.
②Uma ithangi likaphethiloli lingahlanzwa isikhathi eside noma kusetshenziswa udizili ongcolile, ukungcola okukuyo kungase kudonswe emgqeni kawoyela bese kunqwabelana ezindaweni eziwumngcingo noma izihlungi, okubangele ukuvinjelwa komzila kawoyela.Ngemva kokubuza osebenza naye, sathola ukuthi kwakukhona ukushoda kukadizili engxenyeni yesibili yonyaka, futhi udizili ongajwayelekile wawusenesikhathi eside usetshenziswa, futhi isihlungi sikadizili sasingakaze sihlanzwe.Kusolwa ukuthi iphutha likule ndawo.Susa isihlungi.Uma isihlungi singcolile, buyisela isihlungi.Ngesikhathi esifanayo, hlola ukuthi umugqa kawoyela ubushelelezi.Ngisho nangemva kwalezi zinyathelo, umshini awukaqalisi kahle, ngakho lokho kukhishwe njengento engenzeka.
③Umzila wamafutha uvinjwe yi-wax noma amanzi.Ngenxa yesimo sezulu esibanda ebusika, kwaqale kwatholakala ukuthi imbangela yokwehluleka ukuvaleka kwamanzi.Kuyaqondakala ukuthi i-O# diesel yasetshenziswa futhi isihlukanisi samanzi samafutha asizange sikhiphe amanzi.Njengoba kungekho ukuvinjelwa kwe-wax emgqeni kawoyela okutholakala ngesikhathi sokuhlolwa kwangaphambilini, ekugcineni kwatholakala ukuthi iphutha libangelwa ukuvinjelwa kwamanzi.I-drain plug ikhululekile futhi ukugeleza kwamanzi akubushelelezi.Ngemva kokukhipha isihlukanisi samanzi kawoyela, ngathola izinsalela zeqhwa ngaphakathi.Ngemuva kokuhlanza, umshini usebenza ngokujwayelekile futhi iphutha liyaxazululwa.
- Ukuhluleka kukagesi kagandaganda: Ngemva komsebenzi wokushintsha ebusuku, umshini awukwazi ukuqala futhi injini yokuqalisa ayikwazi ukujikeleza.
①Ukuhluleka kwebhethri.Uma injini yesiqalisi ingajiki, inkinga ingase ibe ngebhethri.Uma i-voltage yetheminali yebhethri ikalwa ukuthi ibe ngaphansi kuka-20V (kubhethri engu-24V), ibhethri inephutha.Ngemuva kokwelashwa kwe-sulfation nokushaja, ibuyela kokujwayelekile.
②I-wiring ikhululekile.Ngemva kokuyisebenzisa isikhashana, inkinga isekhona.Ngemva kokuthumela ibhethri ukuthi liyokhandwa, libuyele kwesijwayelekile.Ngalesi sikhathi ngicabange ukuthi ibhethri ngokwalo lilisha, ngakho-ke mancane amathuba okuthi likhishwe kalula.Ngiqale injini futhi ngabona i-ammeter ishintshashintsha.Ngahlola ijeneretha ngathola ukuthi ayinawo amandla okukhipha amandla azinzile.Kukhona izinto ezimbili ezingenzeka ngalesi sikhathi: enye ukuthi i-excitation circuit inephutha, kanti enye iwukuthi i-generator ngokwayo ayikwazi ukusebenza ngokujwayelekile.Ngemva kokuhlola izintambo, kwatholakala ukuthi ukuxhumana okuningana kwakuxege.Ngemuva kokuwaqinisa, i-generator ibuyele kwesijwayelekile.
③Ukulayisha ngokweqile.Ngemva kwesikhathi sokusetshenziswa, ibhethri liqala ukuphinde liphume futhi.Njengoba iphutha elifanayo lenzeka izikhathi eziningi, isizathu siwukuthi imishini yokwakha ngokuvamile yamukela uhlelo locingo olulodwa (isigxobo esinegethivu sisekelwe phansi).Inzuzo i-wiring elula kanye nokugcinwa okulula, kodwa okubi ukuthi kulula ukushisa imishini kagesi.
- Ukusabela kwe-bulldozer kuhamba kancane: isiteringi esiseceleni esingakwesokudla asizweli.Kwesinye isikhathi ingaphenduka, kwesinye isikhathi iphendule kancane ngemuva kokusebenza i-lever.I-steering hydraulic system ikakhulukazi iqukethe isihlungi esimahhadla 1, ipompo lokuqondisa 2, isihlungi esihle esingu-3, i-valve yokulawula isiteringi engu-7, i-brake booster 9, i-valve yokuphepha, ne-cooler kawoyela 5. Amafutha wehydraulic ku-clutch yokuqondisa. indlu ifakwe ku-clutch yokuqondisa.Iphampu yokuqondisa engu-2 idlula kusihlungi sikazibuthe esimaholoholo 1, bese sithunyelwa kusihlungi esihle esingu-3, bese singena kuvalvu yokulawula ukuqondisa 4, i-brake booster kanye nevalve yokuphepha.Uwoyela we-hydraulic okhishwe yivalvu yokuphepha (ingcindezi elungisiwe ingu-2MPa) ugelezela ku-oyili opholile we-bypass valve.Uma umfutho kawoyela we-valve yokudlula uwoyela opholile udlula ukucindezela okusethiwe okungu-1.2MPa ngenxa yokuvaleka kwe-oyili epholile engu-5 noma isistimu yokuthambisa, uwoyela we-hydraulic uzokhishelwa ku-clutch house.Lapho isiteringi sesiteringi sidonswa phakathi, uwoyela we-hydraulic ageleza ku-valve yesiteringi engu-7 engena ku-clutch yokuqondisa.Lapho isiteringi sesiteringi sidonselwa phansi, uwoyela we-hydraulic uyaqhubeka nokugeleza ku-clutch yokuqondisa, okubangela ukuthi i-clutch yokuqondisa inqamuke, futhi ngesikhathi esifanayo agelezele ku-booster yebhuleki ukuze asebenze njengebhuleki.Ngemuva kokuhlaziywa, kucatshangwa ukuthi iphutha lenzekile:
①I-clutch yokuqondisa ayikwazi ukuhlukaniswa ngokuphelele noma ishelele;
②Ibhuleki lokuqondisa alisebenzi.1. Izizathu zokuthi kungani i-clutch ingahlukani ngokuphelele noma ishelele yilezi: izici zangaphandle zihlanganisa ukucindezela kawoyela okunganele okulawula i-clutch yokuqondisa.Umehluko wengcindezi phakathi kwezimbobo B no-C awumkhulu.Njengoba kuphela ukuqondisa okulungile akunandaba futhi ukuqondisa kwesokunxele kuyinto evamile, kusho ukuthi ukucindezela kwamafutha kwanele, ngakho-ke iphutha alikwazi ukuba kule ndawo.Izici zangaphakathi zifaka ukwehluleka kwesakhiwo sangaphakathi se-clutch.Ezicini zangaphakathi, umshini udinga ukuhlakazwa futhi uhlolwe, kodwa lokhu kuyinkimbinkimbi futhi ngeke kuhlolwe okwamanje.2. Izizathu zokuhluleka kwebhuleki lokuqondisa yilezi:①Umfutho wamafutha wamabhuleki onganele.Izingcindezi ezikhumulweni zemikhumbi D kanye no-E ziyafana, okwenza lokhu kube nokwenzeka.②I-friction plate iyashelela.Njengoba umshini ungakaze usetshenziswe isikhathi eside, amathuba okugqoka amapuleti e-friction mancane kakhulu.③I-braking stroke inkulu kakhulu.Qinisa ngetorque engu-90N·m, bese uyibuyisela emuva 11/6 ukuphenduka.Ngemva kokuhlola, inkinga yokuqondisa kwesokudla okungaphenduliwe isixazululiwe.Ngesikhathi esifanayo, kungenzeka ukuthi ukwehluleka kwesakhiwo sangaphakathi se-clutch nakho kukhishwe.Imbangela yephutha ukuthi i-braking stroke inkulu kakhulu.
