Njengezixhobo zokwakha iindlela zomhlaba, iibulldozers zinokugcina izinto ezininzi kunye nabasebenzi, zikhawulezise ukwakhiwa kweendlela, kunye nokunciphisa inkqubela phambili yeprojekthi.Kumsebenzi wemihla ngemihla, ii-bulldozers zinokufumana ukungasebenzi kakuhle ngenxa yokugcinwa okungafanelekanga okanye ukuguga kwezixhobo.Olu lulandelayo lucazululo oluneenkcukacha lwezizathu zoku kusilela:
- I-Bulldozer ayiyi kuqala: Emva kokusetyenziswa okuqhelekileyo, ayiyi kuphinda iqale kwaye akukho msi.Umqali usebenza ngokuqhelekileyo, kwaye ekuqaleni kugwetywa ukuba i-oil circuit iphosakele.Xa usebenzisa i-pump manual ukupompa ioli, ndafumanisa ukuba inani le-oil pumped lanele, kwakungekho moya kwi-oil flow flow, kwaye ipompo yezandla ingasebenza ngokukhawuleza.Oku kubonisa ukuba ukunikezelwa kweoli kuqhelekileyo, umgca weoli awuvaliwe, kwaye akukho kuvuza komoya.Ukuba ngumatshini osanda kuthengwa, ukwenzeka kokungasebenzi kakuhle kwempompo yokutofa kwamafutha (itywina elikhokelayo alivulwanga) lincinci.Ekugqibeleni, xa ndibona i-lever esikiweyo, ndafumanisa ukuba yayingekho kwindawo eqhelekileyo.Emva kokuyijika ngesandla, yaqala ngokuqhelekileyo.Kwagqitywa ukuba impazamo yayikwi-valve ye-solenoid.Emva kokutshintsha i-valve ye-solenoid, injini yasebenza ngokuqhelekileyo kwaye impazamo yasonjululwa.
- Ubunzima bokuqalisa ibulldozer: Emva kokusetyenziswa okuqhelekileyo kunye nokuvalwa, ibulldozer iqala kakubi kwaye ayikhuphi umsi omninzi.Xa usebenzisa i-pump manual ukupompa ioli, inani le-oil pumped alilikhulu, kodwa akukho moya kwi-oil flow flow.Xa impompo yempompo isebenza ngokukhawuleza, i-vacuum enkulu iya kuveliswa, kwaye i-oil pump piston iya kuzifunxa ngokuzenzekelayo.Kugwetywa ukuba akukho ukuvuza komoya kumgca weoli, kodwa kubangelwa ukungcola okuvimba umgca weoli.Izizathu zokuvaleka komzila weoyile zezi:
①Udonga lwangaphakathi lwerabha lombhobho we-oyile lunokwahlula okanye liwe, lubangele ukuvaleka komgca we-oyile.Ekubeni umatshini awuzange usetyenziswe ixesha elide, ukukwazi ukuguga kuncinci kwaye kunokukhutshwa okwethutyana.
②Ukuba itanki yepetroli ayicocwanga ixesha elide okanye idizili engacocekanga isetyenzisiwe, ukungcola okukuyo kunokufunxwa kumgca weoyile kwaye kuqokelele kwindawo emxinwa okanye kwizihluzi, kubangele ukuvaleka komgca weoyile.Emva kokubuza umqhubi, siye safumanisa ukuba kukho ukunqongophala kwedizili kwisiqingatha sesibini sonyaka, kwaye idizili engeyiyo eqhelekileyo yayisetyenziswe ixesha elide, kwaye isihluzo se-diesel asizange sicocwe.Ityala kurhaneleka ukuba kule ndawo.Susa isihluzo.Ukuba isihluzo simdaka, buyisela isihluzo.Ngexesha elifanayo, khangela ukuba umgca weoyile ugudile.Kwanasemva kwala manyathelo, umatshini awukaqalisi ngokufanelekileyo, ke loo nto ikhutshelwe ngaphandle njengento enokwenzeka.
③Umgca weoli uvalwe nge-wax okanye ngamanzi.Ngenxa yemozulu ebandayo ebusika, ekuqaleni kwagqitywa ukuba unobangela wokungaphumeleli kukuvalwa kwamanzi.Kuyaqondwa ukuba i-O# idizili yayisetyenzisiwe kwaye isahluli samanzi se-oyile asizange sikhuphe amanzi.Ekubeni akukho nto i-wax blockage kumgca we-oyile ifunyenwe ngexesha lokuhlolwa kwangaphambili, ekugqibeleni kwagqitywa ukuba iphoso libangelwa ukuvalwa kwamanzi.I-drain plug ikhululekile kwaye ukuhamba kwamanzi akukho mpuluswa.Emva kokususa isahluli samanzi e-oyile, ndafumana intsalela yomkhenkce ngaphakathi.Emva kokucoca, umatshini usebenza ngokuqhelekileyo kwaye impazamo isonjululwe.
- Ukungaphumeleli kombane we-Bulldozer: Emva komsebenzi wokutshintsha ebusuku, umatshini awukwazi ukuqala kwaye i-motor starter ayikwazi ukujikeleza.
①Ukusilela kwebhetri.Ukuba isiqalisi semoto asiyi kujika, ingxaki isenokuba kwibhetri.Ukuba i-terminal voltage yebhetri ilinganiselwa ukuba ingaphantsi kwe-20V (kwibhetri ye-24V), ibhetri inephutha.Emva konyango lwe-sulfation kunye nokutshaja, ibuyela kwisiqhelo.
②I-wiring ikhululekile.Emva kokuyisebenzisa ixeshana, ingxaki isekho.Emva kokuthumela ibhetri ukuba ilungiswe, ibuyele kwisiqhelo.Ngeli xesha ndiye ndacinga ukuba ibhetri ngokwayo yayintsha, ngoko ke kwakungekho ithuba lokuba ikhutshwe ngokulula.Ndiqale injini ndaqaphela iammeter iyaguquguquka.Ndajonga ijenereyitha ndafumanisa ukuba ayinayo ivoltheji ezinzileyo.Kukho izinto ezimbini ezinokwenzeka ngeli xesha: enye kukuba i-excitation circuit iphosakele, kwaye enye kukuba i-generator ngokwayo ayikwazi ukusebenza ngokuqhelekileyo.Emva kokujonga i-wiring, kwafunyaniswa ukuba unxibelelwano oluninzi lukhululekile.Emva kokuwaqinisa, ijenereyitha yabuyela esiqhelweni.
③Ukulayisha ngaphezulu.Emva kwethuba lokusetyenziswa, ibhetri iqala ukukhupha kwakhona.Ekubeni iphutha elifanayo lenzeka amaxesha amaninzi, isizathu kukuba oomatshini bokwakha ngokubanzi bamkela inkqubo yocingo olunye (ipali engalunganga isekelwe).Inzuzo i-wiring elula kunye nokugcinwa okufanelekileyo, kodwa ukungonakali kukuba kulula ukutshisa izixhobo zombane.
- Ukuphendula kwe-bulldozer kucotha: umgca wecala lasekunene awunabungozi.Ngamanye amaxesha inokujika, ngamanye amaxesha iphendule ngokukhawuleza emva kokusebenza kwe-lever.Inkqubo yokulawula i-hydraulic system ikakhulu iqulethe i-filter e-coarse 1, ipompo yokulawula i-2, i-fine filter 3, i-valve yokulawula i-7, i-booster ye-brake 9, i-valve yokukhusela, kunye ne-oyile epholileyo 5. Ioli ye-hydraulic kwi-clutch yokulawula indlu ifunxwa kwi-clutch yokulawula.Ipompo yokulawula i-2 idlula kwisihluzo esirhabaxa samagnetic 1, kwaye emva koko sithunyelwa kwisihluzo esihle 3, kwaye emva koko singene kwivalve yokulawula i-4, i-booster yebhuleki kunye nevalve yokhuseleko.Ioyile yehydraulic ekhutshwe yivalve yokhuseleko (uxinzelelo olulungisiweyo yi-2MPa) iqukuqela kwivalve ye-oyile yokudlula epholileyo.Ukuba uxinzelelo lwe-oyile yevalve ye-oyile yokudlula i-oyile idlula uxinzelelo oluseti lwe-1.2MPa ngenxa yokuvaleka kwe-oyile epholileyo 5 okanye inkqubo yokuthambisa, i-oyile ye-hydraulic iya kukhutshelwa kwi-clutch house.Xa i-lever yokulawula idonsa isiqingatha, ioli ye-hydraulic egeleza kwi-valve yokulawula i-7 ingena kwi-clutch yokulawula.Xa i-lever steering itsalwa phantsi, i-oyile ye-hydraulic iyaqhubeka nokugeleza kwi-clutch yokulawula, ibangela ukuba i-clutch yokulawula ikhuphe, kwaye ngexesha elifanayo ligeleza kwi-booster ye-brake ukuze isebenze njenge-brake.Emva kokuhlalutya, kuchazwa kwangaphambili ukuba impazamo yenzekile:
①I-clutch yokulawula ayikwazi ukuhlukana ngokupheleleyo okanye i-slips;
②Isiqhoboshi sokuqhuba asisebenzi.1. Izizathu zokuba kutheni i-clutch ingahlukani ngokupheleleyo okanye i-slipping yilezi: izinto zangaphandle ziquka ukungonelanga kwengcinezelo yeoli elawula i-clutch yokulawula.Umahluko woxinzelelo phakathi kwe-B kunye ne-C ayinkulu.Ekubeni kuphela ulwalathiso olufanelekileyo alunamvakalelo kwaye ulwalathiso lwekhohlo luqhelekileyo, kuthetha ukuba uxinzelelo lweoyile lwanele, ngoko ke impazamo ayinakuba kule ndawo.Izinto zangaphakathi ziquka ukungaphumeleli kwesakhiwo sangaphakathi se-clutch.Kwimiba yangaphakathi, umatshini kufuneka udityaniswe kwaye uhlolwe, kodwa oku kuyinkimbinkimbi kwaye ayiyi kuhlolwa ixesha.2. Izizathu zokusilela kweziqhoboshi zokuqhuba zezi:①Uxinzelelo lweoyile yebhuleki eyaneleyo.Uxinzelelo kwizibuko D kunye no-E ziyafana, ukukhupha oku kunokwenzeka.②Ipleyiti yefriction iyatyibilika.Ekubeni umatshini awuzange usetyenziswe ixesha elide, ukukwazi ukunxiba ipleyiti ye-friction kuncinci.③I-braking stroke inkulu kakhulu.Qinisa ngetorque ye-90N·m, uze uyijike umva 11/6 ukujika.Emva kovavanyo, ingxaki yokungaphenduli kwasekunene iye yasonjululwa.Ngexesha elifanayo, ukwenzeka kokungaphumeleli kwezakhiwo zangaphakathi ze-clutch nazo zikhutshwe.Unobangela wempazamo kukuba i-braking stroke inkulu kakhulu.
