Izingxenye ze-Volvo excavator bezilokhu zithandwa ngabasebenza embonini yokumba. Isevisi yangemuva - yokuthengisa kanye nekhwalithi yezingxenye zokumba zakwaVolvo ezithengwa abantu abaningi kuqinisekiswe kakhulu kunezabakhiqizi abancane abathile. Kodwa-ke, noma ngabe zinhle kangakanani, ukungasebenzi kahle akunakugwenywa ngemuva kokusetshenziswa isikhathi eside. Ukwazi kabanzi mayelana nezimbangela zokuqhekeka kwamabhulokhi enjini namakhanda angamasilinda kuthenjwa ukuthi kuzoba usizo kuwe.
I. Izizathu zokuqhekeka kwezingxenye zamasilinda we-Volvo excavator Izingxenye ze-injini ye-cylinder block kanye nekhanda le-cylinder ezijwayele ukuqhekeka ngokuvamile zihlobene nesakhiwo sazo. Izingxenye ezivame ukuqhekeka ezinhlotsheni ezahlukene zezinjini zinamaphethini azo. Amabhulokhi enjini namakhanda angamasilinda avamise ukuphonswa ngensimbi empunga, i-alloy cast iron, ne-aluminium alloy. Izakhiwo zabo ziyinkimbinkimbi, futhi zisebenza ngaphansi kwezinga lokushisa eliphezulu, ingcindezi ephezulu, umthwalo oshisayo, nezimo zokulayisha ezishintshayo. Ngakho-ke, izimbobo zesihlabathi kanye nokuqhekeka kuvame ukuvela ku-cylinder block kanye nekhanda le-cylinder.
II. Izixazululo zokuqhekeka kwezingxenye zamasilinda we-Volvo excavator
- Injini inamandla aphezulu kanye nesivinini. Ngesivinini esikhulu, amandla angenayo makhulu, ukucindezeleka kwepuleti eliphansi kuphezulu, futhi kungenzeka ukuqhekeka.
- I-cylinder block inesakhiwo esiyinkimbinkimbi nokuqina kodonga olungalingani. Ngenxa yokuqina kwayo okuphansi, kungenzeka ukuthi imifantu yenzeke kwezinye izingxenye ezibuthakathaka.
- Ngesivinini esikhulu, i-crankshaft iyandindizela, okwandisa umthwalo ku-cylinder block futhi kubangele ukuqhekeka ezingxenyeni ezibuthakathaka.
- Ukugxilisa ingcindezi kwenzeka ekushintsheni phakathi kwezingxenye eziwumshini kanye nezingxenye ezingakamshini ezinobukhulu obuhlukahlukene bodonga. Uma ukugxiliswa kwengcindezi kungaphezu kwengcindezi yangaphakathi eyinsalela ekusakazeni, ukuqhekeka kungenzeka kwenzeke.
- Uma injini isebenza ngaphansi kokulayishwa isikhathi eside, ukucindezeleka ku-cylinder block kuphezulu kakhulu, futhi ingxenye yokuqhekeka ku-cylinder block inkulu.
- Ngokungazelelwe ukungeza amanzi abandayo enjinini ekushiseni okuphezulu kubangela ukucindezeleka okushisayo okweqile ku-cylinder block, okuholela ekuguquguqukeni kwe-cylinder block kanye nokuphuka.
- Ukushuba okwedlulele kokungcola kwamanzi ejazini lamanzi kunciphisa ukudlula kwamanzi okupholisa. Ngesikhathi esifanayo, ngenxa yokudlulisa ukushisa okubi kokungcola kwamanzi, ukusebenza kokushisa - ukuchithwa kwenjini kuyancishiswa. Ikakhulukazi ngemva kokuba umzila wamanzi phakathi kwe-cylinder kanye ne-valve ivinjiwe, ukushisa kwayo - ukuchithwa kuthinteka kakhulu, okwenza ukushisa kwendawo yokusebenza kukhuphuke futhi ukucindezeleka okushisayo kuphezulu kakhulu. Lokhu kungenzeka ezikhathini ezinzima zasebusika futhi kuqhume ngenxa yokwengezwa kungazelelwe kwamanzi ashisayo ashisayo.
- Izidingo zobuchwepheshe zemisebenzi yokulungisa azenziwanga ngokuqinile. Isibonelo, amabhawodi ekhanda lesilinda awaqinisiwe ngendlela ebekiwe kanye netorque, futhi amandla okuqinisa awalingani, okuholela ekuwohlokeni kwesilinda nokuqhekeka eduze kwembobo yebhawodi.
- s.
Ngokusebenzisa le ncazelo engenhla, unokuqonda okuthile ngezimbangela zokwehluleka kokuqhekeka kwamabhuloki enjini namakhanda angamasilinda. Kufanele ukhumbule ukubhekisela kukho ekusetshenzisweni kwansuku zonke ukuze ugweme izimo ezifanayo futhi uthinte ukusetshenziswa.
