Semichina yekuvaka migwagwa yepasi, mabulldozer anogona kuchengetedza zvinhu zvakawanda nevashandi, kukurumidzisa kugadzirwa kwemigwagwa, uye kuderedza kufambira mberi kweprojekiti. Mubasa rezuva nezuva, mabulldozer anogona kusangana nematambudziko nekuda kwekusagadziriswa zvakanaka kana kukwegura kwemidziyo. Zvinotevera ongororo yakadzama yezvikonzero zvekukundikana uku:
- Bulldozer haitangi: Mushure mekushandiswa kwakajairika, haitangizve uye hapana utsi. Starter inoshanda zvakajairika, uye pakutanga zvinoonekwa kuti circuit yemafuta haina kunaka. Pandakashandisa pombi yemaoko kupomba oiri, ndakaona kuti huwandu hwemafuta anopombwa hwakakwana, pakanga pasina mhepo mumafuta, uye pombi yemaoko inogona kushanda nekukurumidza. Izvi zvinoratidza kuti mafuta anowanikwa zvakajairika, tambo yemafuta haina kuvharwa, uye hapana mhepo inobuda. Kana iri muchina uchangobva kutengwa, mukana wekuti pombi yemafuta inopinda mumafuta isashande zvakanaka (lead seal haina kuvhurwa) idiki. Pakupedzisira, pandakaona cut-off lever, ndakaona kuti yakanga isiri munzvimbo yakajairika. Mushure mekuitenderedza neruoko, yakatanga zvakajairika. Zvakaonekwa kuti dambudziko raiva mu solenoid valve. Mushure mekutsiva solenoid valve, injini yakashanda zvakajairika uye dambudziko rakagadziriswa.
- Kuoma kutanga bulldozer: Mushure mekushandiswa uye kudzimwa, bulldozer inotanga zvisina kunaka uye haiburitse utsi hwakawanda. Pakushandisa pombi yemaoko kupomba oiri, huwandu hwemafuta anopombwa hausi hukuru, asi hapana mhepo inoyerera mumafuta. Kana pombi yemaoko ikashanda nekukurumidza, vacuum hombe inogadzirwa, uye piston yepombi yemafuta inozodzoka yega. Zvinoonekwa kuti hapana mhepo inobuda mumutsara wemafuta, asi zvinokonzerwa nekusachena kuri kuvhara mutsetse wemafuta. Zvikonzero zvekuvharika kwemutsetse wemafuta ndeizvi:
①Rusvingo rwemukati mepombi yemafuta runogona kupatsanuka kana kudonha, zvichikonzera kuvharika kwetambo yemafuta. Sezvo muchina wacho usina kushandiswa kwenguva yakareba, mukana wekukwegura mudiki uye unogona kubviswa kwenguva pfupi.
②Kana tangi remafuta rikasacheneswa kwenguva yakareba kana kuti dhiziri risina kuchena rikashandiswa, tsvina iri mariri inogona kusvetwa mumutsara wemafuta youngana munzvimbo dzakamanikana kana mafirita, zvichikonzera kuvharika kwemutsetse wemafuta. Mushure mekubvunza mushandi, takaziva kuti pakanga paine kushomeka kwedhiziri muhafu yechipiri yegore, uye dhiziri risingawanzo kushandiswa rakanga rashandiswa kwenguva yakati, uye firita redhiziri rakanga risati rambocheneswa. Chikanganiso chinofungidzirwa kuti chiri munzvimbo iyi. Bvisa firita. Kana firita rakasviba, tsiva firita. Panguva imwe chete, tarisa kana mutsetse wemafuta wakatsetseka. Kunyangwe mushure mematanho aya, muchina hausati watanga zvakanaka, saka izvozvo hazvigoneke.
③Mutsetse wemafuta wakavharwa newakisi kana mvura. Nekuda kwemamiriro ekunze anotonhora munguva yechando, pakutanga zvakaonekwa kuti chikonzero chekukundikana kwaive kuvharika kwemvura. Zvinonzwisisika kuti O# diesel yakashandiswa uye oil-water separator haina kumboburitsa mvura. Sezvo pasina kuvharika kwewakisi mumutsetse wemafuta kwakawanikwa panguva yekuongorora kwakapfuura, zvakazoonekwa kuti kukanganisa kwakakonzerwa nekuvharika kwemvura. Puragi redhireni rakasununguka uye kuyerera kwemvura hakuna kutsetseka. Mushure mekubvisa oil-water separator, ndakawana chando chiri mukati. Mushure mekuchenesa, muchina unoshanda zvakanaka uye dambudziko rinogadziriswa.
- Kukundikana kwemagetsi eBulldozer: Mushure mekushanda kwehusiku, muchina haugone kutanga uye mota yekutanga haigone kutenderera.
①Kukundikana kwebhatiri. Kana mota yekutanga ikasatenderera, dambudziko rinogona kunge riri pabhatiri. Kana voltage yebhatiri ikayerwa kuti iri pasi pe20V (yebhatiri re24V), bhatiri harina kunaka. Mushure mekurapwa nekuchajwa kwesimbi, rinodzokera pakuva rakajairika.
②Waya dzemagetsi dzakasununguka. Mushure mekuishandisa kwenguva yakati, dambudziko richiripo. Mushure mekutuma bhatiri kuti rigadziriswe, rakadzokera pakare. Panguva iyi ndakafunga kuti bhatiri pacharo raive idzva, saka pakanga pasina mukana wekuti riburitswe zviri nyore. Ndakabatidza injini ndikaona ammeter ichichinja-chinja. Ndakatarisa jenareta ndikaona kuti rakanga risina simba remagetsi rakagadzikana. Pane mikana miviri panguva ino: imwe ndeyekuti circuit yekumutsa haina kunaka, uye imwe ndeyekuti jenareta pachayo haigone kushanda zvakanaka. Mushure mekutarisa waya, zvakaonekwa kuti kubatana kwakawanda kwakanga kwakasununguka. Mushure mekuisimbisa, jenareta yakadzokera pakare.
③Kuwedzeredza. Mushure menguva yekushandiswa, bhatiri rinotanga kuburitsa zvakare. Sezvo zvikanganiso zvakafanana zvichiitika kakawanda, chikonzero ndechekuti michina yekuvaka inowanzoshandisa sisitimu yewaya imwe chete (danda risina simba rinoiswa pasi). Chakanakira ndeye waya dziri nyore uye kugadzirisa kuri nyore, asi chakaipa ndechekuti zviri nyore kupisa michina yemagetsi.
- Mhinduro yekufambisa yebulldozer inononoka: kutungamira kurudyi hakunzwisisike. Dzimwe nguva inogona kutenderera, dzimwe nguva inoita zvishoma nezvishoma mushure mekushandisa lever. Sisitimu ye hydraulic yekufambisa inonyanya kuve nefirita 1, pombi yekufambisa 2, firita 3, vharuvhu yekudzora 7, brake booster 9, vharuvhu yekuchengetedza, uye oiri inotonhorera 5. Oiri ye hydraulic iri mu steering clutch housing inosvetwa mu steering clutch. Pombi yekufambisa 2 inopfuura nepakati pe magnetic rough filter 1, yozotumirwa ku fine filter 3, yozopinda mu steering control valve 4, brake booster uye safety valve. Oiri ye hydraulic inoburitswa ne safety valve (adjusted pressure i2MPa) inoyerera mu oil cooler bypass valve. Kana oil pressure ye oil cooler bypass valve ikadarika set pressure 1.2MPa nekuda kwekuvharika kwe oil cooler 5 kana lubrication system, oil ye hydraulic inoburitswa mu steering clutch housing. Kana steering lever ikadhonzwa pakati, oil ye hydraulic inoyerera mu steering control valve 7 inopinda mu steering clutch. Kana chibatiso chekutyaira chikadhonzwa pasi, mafuta ehydraulic anoramba achiyerera achipinda muchikamu chekutyaira, zvichiita kuti chikamu chekutyaira chibude, uye panguva imwe chete chinoyerera chichipinda muchikamu chekusimudzira mabhureki kuti chishande sebhureki. Mushure mekuongorora, zvinotanga zvaonekwa kuti kutadza kwakaitika:
①Clutch yekufambisa haigoni kuparadzaniswa zvachose kana kutsvedza;
②Brake rekufambisa harishande. 1. Zvikonzero nei clutch isina kupatsanurwa zvachose kana kutsvedza ndeizvi: zvinhu zvekunze zvinosanganisira kumanikidzwa kwemafuta kusina kukwana kudzora clutch yekufambisa. Musiyano wekumanikidzwa pakati pemaports B neC hausi mukuru. Sezvo kutungamira kwekurudyi chete kusinganzwi uye kutungamira kwekuruboshwe kwakajairika, zvinoreva kuti kumanikidzwa kwemafuta kwakakwana, saka kukanganisa hakugone kuve munzvimbo iyi. Zvinhu zvemukati zvinosanganisira kukundikana kwemukati kweclutch. Kune zvinhu zvemukati, muchina unofanirwa kupatsanurwa uye kuongororwa, asi izvi zvakaoma uye hazvizoongororwa parizvino. 2. Zvikonzero zvekukundikana kwebrake rekufambisa ndeizvi:①Kumanikidzwa kwemafuta emabhureki kusina kukwana. Kumanikidzwa kwemaports D neE kwakafanana, zvichibvisa mukana uyu.②Purati yekukweshana inotsvedza. Sezvo muchina wacho usati washandiswa kwenguva yakareba, mukana wekuti mapurati ekukweshana asashande wakaderera.③Kurovera kwebhureki kwakakura zvakanyanya. Simbisa ne torque ye 90N·m, wobva waidzosera kumashure ka1 1/6. Mushure mekuyedza, dambudziko rekutungamira kurudyi risingashande zvakanaka ragadziriswa. Panguva imwe chete, mukana wekuti clutch isashande zvakanaka mukati memota hausiwo. Chikonzero chekukanganisa ndechekuti braking stroke yakakura zvakanyanya.
