I-Tensioner - Isixhobo sokulungelelanisa i-tensioner yebhanti lexesha kunye nekhonkco lexesha.
Isenzo se-tensioner.
Ngaphantsi kokuhanjiswa kwebhanti lexesha okanye ikhonkco lexesha, i-camshaft iqhuba i-valve ukuba ivule kwaye ivale ngexesha elifanelekileyo, kwaye igqibezele iinkqubo ezine zokungena, ukunyanzeliswa, ukusebenza kunye nokukhupha ngepiston. Ngenxa yokuba ibhanti lexesha kunye nekhonkco lexesha liya kuxhuma xa lihamba ngesantya esiphakathi kunye nesantya esiphezulu, kwaye ibhanti lexesha liya kunyuka kwaye likhubaze ngenxa yezinto eziphathekayo kunye nokunyanzeliswa kwebhanti ekusebenziseni ixesha elide, okubangelwa ukuchithwa kwexesha le-valve engachanekanga, okubangelwa iindleko zepetroli zesithuthi, ubuthathaka, ukunkqonkqoza kunye nokunye ukungaphumeleli. Xa uninzi lokutsiba amazinyo ngenxa yokuba ivalve ivuleke phambi kwexesha okanye ivalwe kade kakhulu iya kubangela ivalve kunye nomonakalo wokungqubana kwepiston ukuya phezulu kwi-injini.
Ukuze uvumele ibhanti lexesha kunye nekhonkco lexesha ligcine idigri efanelekileyo yokuqinisa, oko kukuthi, kungekhona ngenxa yokukhululeka kakhulu kunye nokutsiba amazinyo kwaye kungekhona ngenxa yomonakalo onzima kakhulu, kukho inkqubo ekhethekileyo yokuqinisa, equkethe i-tensioner kunye nesondo eliqinileyo okanye umzila wesikhokelo. I-tensioner ibonelela ngoxinzelelo olubhekiselele kwibhanti okanye ityathanga, i-tensioner inxibelelana ngokuthe ngqo nebhanti lexesha, kwaye isikhokelo sikaloliwe sinxibelelana ngokuthe ngqo nekhonkco lexesha, kwaye basebenzise uxinzelelo olunikezwa yi-tensioner kuyo ngelixa bebaleka ibhanti okanye ityathanga, ukuze bagcine inqanaba elifanelekileyo le-tensioner.
Loluphi uphawu oluya kwaphuka i-tensioner yejenereyitha yemoto
Ukwaphulwa koxinzelelo lwejenereyitha yemoto kuya kukhokelela ekonyukeni kokusetyenziswa kwamafutha, ukungabikho kwamandla, ukunkqonkqoza, isandi esingaqhelekanga se-injini kunye nezinye iimpawu. i
I-tensioner guides kwaye iqinisa ibhanti lexesha le-injini okanye ikhonkco lexesha, liqinisekisa ukuba la malungu ahlala ekwimeko engcono yokuqiniswa. Xa i-tensioner yonakalisiwe, iya kubangela ukuba ibhanti lexesha okanye ikhonkco likhululeke, eliya kukhokelela kuluhlu lweengxaki. Okokuqala, ukusetyenziswa kwepetroli kuya kwanda ngenxa yokuba isixokelelwano sexesha asiyi kusebenza kakuhle, nto leyo ekhokelela ekunciphiseni ukusebenza kakuhle kwenkqubo yesivalo se-injini. Okwesibini, ukunqongophala kwamandla kungenxa yokuba ivalve kunye nepiston ziyasebenzisana nengxaki, okukhokelela ekuphumeni kwamandla emoto ngokubanzi. Ukongezelela, isiganeko sokunkqonkqoza sinokuthi senzeke, esibangelwa ukudibanisa okungafanelekanga kwevalve kunye nepiston ngexesha lokunyakaza. Ekugqibeleni, ingxolo ye-injini engaqhelekanga luphawu olucacileyo, kuba ukucotha kwebhanti lexesha okanye ikhonkco kuya kubangela ingxolo engaqhelekanga ngexesha lokusebenza.
Ukuba i-tensioner yonakele kwaye ayitshintshwa kwangethuba, oko kunokubangela iingxaki ezinzulu. I-injini isenokuhexa, ibe nobunzima ekulayitheni, okanye ide isilele ukuqalisa kwiimeko ezimandundu. Ukongeza, i-valve inokukhubazeka, ibangele umonakalo kwizinto ze-injini. Ukuba i-tensioner ayiphumelelanga ngokupheleleyo, inokubangela ukuba ibhanti lisilele ukuqhuba kakuhle kwaye ekugqibeleni ibangele ukuba imoto yonakale.
Ingaba ivili loxinzelelo lwesondo ingxolo engaqhelekanga yonzakalisa imoto?
Isandi esingaqhelekanga sevili eliqiniswayo ngenene siya kubangela umonakalo kwinqwelo-mafutha, kwaye ukuba ayitshintshwa kwangethuba, oko kukhokelela kwiingxaki zokhuseleko ekuqhubeni, ezifana nejita ye-injini, ubunzima bomlilo, kwanokungakwazi ukuyibetha imoto. Le meko inokuthi yenzeke xa isondo lokuqinisa linesandi esingaqhelekanga, ngoko ke kuyimfuneko ukubuyisela ivili lokuqinisa ngexesha. Ukuba ayiphathwanga ngexesha, isandi esingaqhelekanga sevili eliqiniswayo sinokuba nemiphumo emibi kwimoto, njenge-valve deformation.
Ivili eliqinisayo yinxalenye ebalulekileyo ye-injini, elawula ukuqina kwebhanti le-injini ngokudibanisa i-injini kunye ne-gearbox ukuqinisekisa ukusebenza okuqhelekileyo kwe-injini. Ukuba kukho ingxaki kwivili eliqiniswayo, injini inokushukuma, ubunzima bomlilo kunye nezinye iimeko, eziya kuchaphazela ukhuseleko lokuqhuba. Ngoko ke, kucetyiswa ukuba utshintshe ivili lokuqinisa ngexesha xa kukho isandi esingaqhelekanga sokuqinisekisa ukusebenza okuqhelekileyo kwesithuthi.
Isandi esingaqhelekanga sevili loxinzelelo sinokubangela ijitha ye-injini, kuba injini iya kuchatshazelwa livili loxinzelelo ngexesha lokusebenza, okukhokelela ekusebenzeni okungazinzanga. Ukongeza, isandi esingaqhelekanga sevili eliqinisayo sinokubangela ubunzima bokutshisa, okwenza isithuthi singakwazi ukuqala ngokuqhelekileyo. Ukuba kukho ingxaki ngevili eliqinisayo, mhlawumbi akunakwenzeka ukuba ukubetha imoto. Ngoko ke, umnini kufuneka anikele ingqalelo kwimeko yevili lokuqinisa kwaye ayitshintshe ngexesha.
Impembelelo yesandi esingaqhelekanga sokuqina kwevili kwimoto ayinakungahoywa, ukuba ayitshintshwanga ngexesha, kunokukhokelela kwiingxaki ezinzulu ezifana ne-valve deformation. Umnini kufuneka ajonge imeko yevili loxinzelelo rhoqo ukuqinisekisa ukusebenza okuqhelekileyo kwe-injini. Ukuba kukho isandi esingaqhelekanga, ivili lokwandisa kufuneka litshintshwe ngokukhawuleza ukuthintela umonakalo ongakumbi kwi-injini. Ngamafutshane, isandi esingaqhelekanga sevili eliqinisayo siya kubangela umonakalo kwimoto kwaye kufuneka kujongwane nayo ngexesha.
