Izophuka uma inganakekelwa.
Uma uchungechunge lwesithuthuthu lungagcinwa isikhathi eside, luzogqwala ngenxa yokuntuleka kwamafutha namanzi, okuholela ekungakwazini ukuhlangana ngokugcwele nepuleti lochungechunge lwesithuthuthu, okuzokwenza ukuthi uchungechunge luguge, luphuke, futhi luwe. Uma uchungechunge lukhululekile kakhulu, isilinganiso sokudlulisa kanye nokudluliselwa kwamandla akunakuqinisekiswa. Uma uchungechunge luqinile kakhulu, luzoguga futhi luphuke kalula. Uma uchungechunge lukhululekile kakhulu, kungcono ukuya esitolo sokulungisa ukuze uhlolwe futhi ushintshwe ngesikhathi.
Izindlela zokulungisa uchungechunge lwesithuthuthu
Indlela engcono kakhulu yokuhlanza iketanga elingcolile ukusebenzisa isihlanzi seketanga. Kodwa-ke, uma uwoyela wenjini ubanga ukungcola okufana nobumba, kuyasebenza futhi ukusebenzisa igrisi engena ngaphakathi engeke ilimaze indandatho yokuvala irabha.
Amaketanga adonswa yi-torque lapho esheshisa futhi adonswa yi-torque ebuyela emuva lapho ehlisa ijubane avame ukudonswa njalo ngamandla amakhulu. Kusukela ngasekupheleni kweminyaka yama-1970, ukuqina kweketanga kuye kwathuthuka kakhulu kusukela kwavela iketanga elivalwe ngamafutha elivala uwoyela ogcobayo phakathi kwezikhonkwane nezihlahla ngaphakathi kweketanga.
Ukubonakala kweketanga elivalwe ngowoyela kwandisa impilo yeketanga ngokwalo, kodwa yize kukhona uwoyela wokugcoba phakathi kwezikhonkwane zangaphakathi kanye nama-bushings eketanga ukusiza ukugcoba, amapuleti eketanga ahlanganiswe phakathi kwe-chainring neketanga, phakathi kweketanga ne-bushing, kanye nakuzo zombili izinhlangothi zeketanga. Izivalo zerabha phakathi kwezingxenye zisadinga ukuhlanzwa kahle futhi zigcotshwe ngamafutha ngaphandle.
Nakuba isikhathi sokulungisa sihluka phakathi kwezinhlobo ezahlukene zeketanga, iketanga ngokuyisisekelo lidinga ukuhlanzwa nokugcotshwa ngamafutha njalo ngemva kwamakhilomitha angu-500 okushayela. Ngaphezu kwalokho, iketanga lidinga nokugcinwa linjalo ngemva kokugibela ngezinsuku zemvula.
Akufanele kube khona amaqhawe acabanga ukuthi noma engafaki uwoyela wenjini, injini ngeke ibole. Kodwa-ke, abanye abantu bangase bacabange ukuthi ngenxa yokuthi iyiketanga elivalwe ngowoyela, akunandaba ukuthi uligibela kude. Ngokwenza lokhu, uma ukugcoba phakathi kwendandatho yeketanga neketanga kuphela, ukungqubuzana okuqondile phakathi kwezingxenye zensimbi kuzobangela ukuguguleka.
