Iyini ibhulokhi yesilinda yezimoto?
Ibhlokhi yenjini iyisakhiwo esiyisisekelo sokusekela injini, esivame ukubizwa ngokuthi ibhlokhi yesilinda. Njengengxenye eyinhloko yenjini, ihlanganisa amasilinda ahlukahlukene kanye ne-crankcase ibe yinye, yakha uhlaka olusekelayo lokufaka ama-piston, ama-crankshaft, nezinye izingxenye.
Imisebenzi eyinhloko yebhulokhi yesilinda ifaka:
- Njengesisekelo sokuhlanganiswa kwazo zonke izingxenye zenjini, iqukethe amabhomu esilinda (lapho ama-piston ehamba khona emuva naphambili), amajakethi amanzi okupholisa (ukuqondisa ukujikeleza kwe-coolant ukuze kuqedwe ukushisa), kanye nezindlela zikawoyela (ukugcoba izingxenye ezibalulekile). Iphinde isebenze kanye nekhanda lesilinda ukwakha igumbi lokushisa, elimelana namazinga okushisa aphezulu kanye nokucindezeleka futhi lihlanganyela ekuguquleni amandla okushisa kusuka ekushisweni kukaphethiloli abe amandla omshini.
- Ngokuphathelene nezinto zokwakha kanye nesakhiwo, ibhulokhi yesilinda ngokuvamile yenziwe ngensimbi ephothiwe noma i-aluminium alloy - amabhulokhi ensimbi ephothiwe anezinzuzo ezifana namandla aphezulu, ukumelana nokucindezela okuphezulu kanye nokushisa okuphezulu, kanye nezindleko eziphansi, okwenza afaneleke kumamodeli abeka phambili ukuzinza; amabhulokhi e-aluminium alloy alula, asiza ukonga amandla, kodwa anokumelana nokuguguleka okubuthakathaka futhi avame ukudinga ama-cylinder liner, futhi avame ukusetshenziswa ezimotweni ezincane. Ngokwesakhiwo, ibhulokhi yesilinda ingaba ngeyomugqa oqondile, enomumo ongu-V, noma ephikisana ngokuvundlile, ethinta ngqo ibhalansi, ukukhishwa kwamandla, kanye nokuphathwa kwenjini yemoto.
Ukwakheka kwebhulokhi yesilinda kubalulekile ekusebenzeni kahle kwenjini, njengoba ukunemba kwemigodi yesilinda kuthinta ukuvalwa kwegumbi lokushisa, izimbambo zokuqinisa zithuthukisa amandla esakhiwo, futhi ziqinisekise ukuthi injini isebenza kahle ngaphansi komthwalo omkhulu.
Ukwakheka kwebhulokhi yesilinda kanye nokukhethwa kwezinto ezisetshenziswayo kunemiphumela ebalulekile ekusebenzeni kwenjini. Amabhulokhi ensimbi avamile anamandla aphezulu, ukumelana nokuguguleka okuhle, kanye nezindleko eziphansi, okwenza afaneleke kumamodeli adinga ukuqina; amabhulokhi e-aluminium alloy aziwa ngesisindo sawo esilula, ukuhanjiswa kahle kokushisa, futhi asiza ekunciphiseni isisindo semoto, ukuthuthukisa ukonga uphethiloli, kanye nokunciphisa isikhathi sokufudumeza, kodwa abiza kakhulu.
Ukuqhekeka kwe-cylinder block kudinga ukwelashwa okusheshayo ukuze kugwenywe ukwehluleka okukhulu. Okokuqala, yeka ukusebenza kwenjini bese ulinda ukupholisa okuphelele. Bese, hlanza amabala kawoyela azungeze ukuqhekeka bese uhlola ubukhulu, ukujula, kanye nendawo yokuqhekeka ukuze kutholakale uhlelo lokulungisa.
Ukukhetha indlela yokulungisa kuncike ebunzimeni bokuqhekeka, izinto ze-cylinder block (njengensimbi ephonswe noma i-aluminium alloy), kanye nokucatshangelwa kwezindleko. Izindlela ezivamile zifaka:
- Ukulungiswa kokushisela: kufanelekile emifantwini emincane nebekwe endaweni efanele. Amabhlogo ensimbi asebenzisa ukushisela ngegesi, kuyilapho amabhlogo e-aluminium alloy edinga ukushisela nge-argon arc noma amasu okushisela nge-aluminium; ngaphambi kokulungisa, hlanza kahle bese ugaya umfantu, bese wenza ukwelashwa kokushisa ngemva kokushisela ukuze uqede ukucindezeleka. Le ndlela ingabizi kakhulu kodwa idinga amakhono aphezulu obuchwepheshe.
- I-Metal filler noma i-sealant: uma kunemifantu engajulile, sebenzisa ama-filler ensimbi akhethekile noma ama-sealant ngqo ukuze ugcwalise imifantu; ukusebenza kulula, akudingi imishini eyinkimbinkimbi, kodwa kunamandla aphansi kunokushisela futhi kufanelekile ukulungiswa kwesikhashana noma okulula. Ukufaka noma ukubhoboza isilinda nokufaka i-liner yesilinda esikhundleni: Le ndlela isetshenziselwa imifantu emikhulu noma eyinkimbinkimbi yesikhundla. Ngokubhoboza isilinda ukuze kwandiswe ububanzi nokufaka i-liner entsha yesilinda, isakhiwo singaqiniswa. Kubiza kakhulu kodwa kungabuyisela amandla omzimba wesilinda. Le ndlela ingacatshangelwa lapho umzimba wesilinda omanzi uqhekekile.
Ukufaka esikhundleni somzimba wesilinda: Lesi yisisombululo esithembeke kakhulu uma ukuqhekeka kunzima (njengokungena noma ukubandakanya isakhiwo). Kuxazulula inkinga ngokuphelele kodwa kuyabiza. Kudinga ukufanisa imininingwane yokuqala yefektri nokuqinisekisa ukunemba kokufakwa.
Kungakhathaliseki ukuthi iyiphi indlela ekhethiwe, kubalulekile ukuthi ochwepheshe abangochwepheshe basebenze futhi bahlole i-piston, amasongo e-piston, nezinye izingxenye ezihlobene ukuze kugwenywe umonakalo ohambisana nayo. Ngemva kokulungiswa, kufanele kwenziwe ukuhlolwa kokucindezela ukuqinisekisa ukusebenza kokuvala. Ukugcinwa njalo kwenjini kufanele kwenziwe ukuze kuvinjelwe ukuphinda kuqhekeke.
