Iyini intonga yokuxhuma? Yiziphi izici zenjini yokuxhuma induku enomsindo?
I-bearing rod bearing iyingxenye exhuma iphinikhodi, futhi umsebenzi wayo oyinhloko ukunciphisa ukuguga kwephinikhodi.
Isiphetho esikhulu senduku yokuxhuma i-crosshead ngokuvamile senziwa ngokuhlukana, bese sixhunywa ku-shaft ngokuxhuma ama-rod bolts, futhi indawo yayo yangaphakathi ivame ukuphonswa i-antifriction alloy.
Ukuze uthole ama-bearings amakhulu okuphela ngaphandle kwenduku yokuxhuma e-cross-head, ingxenye engenhla ivame ukuhlanganiswa ne-shaft, kuyilapho isembozo esingaphansi esingaphansi sikhiqizwa ngokwehlukana, bese sixhunyaniswa nengxenye engenhla ngokuxhuma ama-bolts wenduku, kanye nendawo yangaphakathi engaphezulu. kanye nama-halves aphansi okuthwala afakwe i-bearing bushing.
Esakhiweni sokuthwala, indawo engaphakathi yomkhono we-shaft ibhobozwa ngezimbobo zikawoyela, kanti amanye ama-oil grooves aklanyelwe ukwenza lula ukugcotshwa kwamafutha okugcoba. Ukwengeza, ukuzilungisa noma induku yesikhulumi ama-bearings amancane-amakhanda avame ukusetshenziswa esakhiweni sokuxhuma izinduku.
Umsebenzi wokuthwala induku yokuxhuma ukunciphisa ukuguga kwephinikhodi, futhi ukungqubuzana phakathi kwephinikhodi ne-shaft kungancishiswa ngempumelelo ngokuxhuma iphinikhodi ne-shaft, ngaleyo ndlela kunwetshwe impilo yesevisi yephinikhodi.
Ngasikhathi sinye, ukuthwala induku yokuxhuma nakho kungathuthukisa ukusebenza nokusebenza kahle kwenjini, futhi kunciphise umsindo nokudlidliza kwenjini. Lokhu kungenxa yokuthi ukuxhuma ama-rod bearings kunganciphisa ukungqubuzana nokuguga ngaphakathi kwenjini, ngaleyo ndlela kuthuthukise ukusebenza kahle nokuzinza kwenjini.
Isakhiwo samabhering wenduku yokuxhuma ngokuvamile sihlanganisa i-crosshead yokuxhuma i-crosshead ama-bearings amaphethelo amakhulu kanye nama-bolts enduku yokuxhuma, lapho i-crosshead exhuma induku enkulu yama-bearings avame ukwakhiwa ngokuhlukana, futhi ama-bearings amakhulu angenayo i-crosshead yokuxhuma induku aklanyelwe ucezu olulodwa.
Ukwengeza, ukuzilungisa noma ipulatifomu yokuxhuma izintambo ezincane-amakhanda amancane avame ukusetshenziswa esakhiweni sokuxhuma amabhorethi ukuze kuqinisekiswe ukusebenza okuvamile nokuzinza kwenjini.
Ngamafuphi, ukuhlanganisa izintambo kuyingxenye ebaluleke kakhulu yenjini yemoto, enganciphisa ngempumelelo ukuguga kwephinikhodi, ithuthukise ukusebenza nokusebenza kahle kwenjini, futhi inciphise umsindo nokudlidliza kwenjini.
Ngakho-ke, ukuklama kanye nokukhiqizwa kwezinsimbi zokuxhuma izintambo kudingeka kuqine kakhulu ukuze kuqinisekiswe izinga nokusebenza kwazo. Enqubweni yokukhiqiza izimoto, izinto ezisezingeni eliphezulu kanye nezinqubo zokukhiqiza zidinga ukukhethwa ukuze kuqinisekiswe impilo yesevisi nokusebenza kokuxhuma ama-rod bearings. Ngesikhathi esifanayo, ukuhlolwa okuvamile nokushintshwa kwezinsimbi zokuxhuma kungenye yezinyathelo ezibalulekile zokuqinisekisa ukusebenza okuvamile kwenjini.
Umsindo ongavamile wokuthwala induku yokuxhuma ubonakala njengomsindo we-clank oqhubekayo lapho injini ishesha ukusuka esivinini esingenzi lutho, futhi lapho isivinini siphezulu, umsindo omkhulu, ongahlangene nokushintsha kwezinga lokushisa lenjini. Lapho ukuthwala kuxega kakhulu, kuzoba nomsindo osobala ngesivinini esingenzi lutho, umsindo uzoqina lapho umthwalo ukhuphuka, futhi umsindo uzoba buthaka kakhulu noma unyamalale lapho umlilo uvela.
Izindlela zokubhekana nomsindo ongajwayelekile wezinduku zokuxhuma zihlanganisa:
1. Yenza ukuhlolwa kwesivinini esiguquguqukayo kanye nokuhlolwa kwe-cylinder misfire, kuhlanganiswe nokuzwakala ngokuphindaphindiwe, uma umsindo ukhula ngokunyuka kwesivinini senjini, umsindo osheshayo we-jitter throttle ugqamile, ixhuma induku enomsindo ongajwayelekile.
2. Ngejubane elingenalutho, isivinini esiphakathi kanye nesivinini esikhulu, ukuhlolwa komlilo we-cylinder, uma umsindo we-cylinder ubuthakathaka kakhulu noma unyamalala ngemva kokucisha, futhi uvela ngokushesha ngesikhathi sokubusa, kunganqunywa ukuthi intambo yokuxhuma ye-cylinder ayijwayelekile.
3. Sebenzisa i-stethoscope noma i-screwdriver yesibambo eside ukuze uthole i-auscultation, uma umsindo ungabonakali, kodwa umsindo ongavamile ngaphansi kwenjini uyabonakala, umsindo ongavamile wokuthwala induku yokuxhuma.
4. Hlola umfutho kawoyela. Uma umsindo ongavamile unzima futhi uhambisana nomfutho ophansi kawoyela, kusho ukuthi imvume phakathi kwe-bearing nejenali inkulu kakhulu.
Isizathu somsindo ongavamile wokuthwala induku yokuxhuma kungase kube ngenxa yokuvunyelwa ngokweqile phakathi kwesihlahla esithwala induku yokuxhuma kanye nejenali yenduku yokuxhuma, okuholela ekunciphiseni ukuqina kwefilimu kawoyela, ukwehla kwamandla okuthwala, ukuwohloka kwesimo sokuthambisa. , nomsindo ongajwayelekile obangelwa ukungqubuzana komngcele noma ukungqubuzana okomile. Kungase futhi kube ukuthi umzila kawoyela omkhulu we-crankshaft uvaliwe, isikrini sokuhlunga singcolile, i-valve ye-bypass inephutha, iphampu kawoyela inephutha, kanti ezinye izizathu ziholela ekucindezelweni kawoyela okuphansi kanye nokugcotshwa okungekuhle kwesihlahla esithwalayo.
Sicela usishayele uma udinga imikhiqizo enjalo.
UZhuo Meng Shanghai Auto Co., Ltd. uzibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS wamukelekile ukuzithenga.
