Ukunxiba kunye nefuthe leringi yepiston yemoto
2021-08-03
1. Indandatho yepiston ibuyisela phakathi kwamanqaku afileyo aphezulu nasezantsi, kwaye isantya sitshintsha ukusuka kwisimo esisisigxina ukuya kwi-30m / s, kwaye sitshintsha kakhulu ngale ndlela.
2. Xa wenza i-reciprocating motion, uxinzelelo lwe-cylinder lutshintsha kakhulu ngexesha lokungena, ukunyanzeliswa, umsebenzi kunye nokukhupha imivimbo yomjikelezo wokusebenza.
3. Ngenxa yempembelelo yokutshatyalaliswa kokutsha, ukuhamba kwentsimbi yepiston kudla ngokuqhutyelwa kwiqondo lokushisa eliphezulu, ngakumbi i-gas ring. Ngaphantsi kwesenzo sekhemikhali sokushisa okuphezulu kunye noxinzelelo oluphezulu kunye neemveliso ezivuthayo, ifilimu yeoli inzima ukuseka, ukwenzela ukuba ikwazi ukufikelela kwi-lubrication epheleleyo. Kunzima, kwaye rhoqo kwimeko yokuthambisa okubalulekileyo.
Phakathi kwazo, izinto kunye nokuma kweringi yepiston, izinto kunye nesakhiwo se-cylinder liner piston, isimo sokuthambisa, uhlobo lwesakhiwo se-injini, iimeko zokusebenza, kunye nomgangatho wepetroli kunye neoli yokuthambisa zizinto eziphambili. Ngokuqinisekileyo, kwi-cylinder efanayo, impembelelo yesimo sokuthambisa ekunxityweni kweringi yepiston ichanekile. Eyona nto ifanelekileyo yokuthambisa phakathi kweendawo ezimbini zokutyibilika kukuba kukho ifilimu ye-oyile efanayo phakathi kweendawo ezimbini zokutyibilika. Nangona kunjalo, le meko ayikho enyanisweni, ngakumbi kwindandatho yomoya, ngenxa yefuthe lobushushu obuphezulu, kunzima ukuseka imeko yokuthambisa ilungele ngakumbi.
Ukunciphisa njani ukunxitywa kwamakhonkco episton
Zininzi izinto ezichaphazela ukunxitywa kweringi yepiston, kwaye ezi zinto zihlala zithungelana. Ukongeza, uhlobo lwe-injini kunye neemeko zokusetyenziswa zihlukile, kwaye ukunxiba kweringi yepiston kukwahluke kakhulu. Ngoko ke, ingxaki ayikwazi ukusonjululwa ngokuphucula isakhiwo kunye nezinto eziphathekayo zeringi yepiston ngokwayo. Inokuqala ikakhulu kule miba ilandelayo: i-piston ring kunye ne-cylinder liner Izinto kunye nokuhambelana kakuhle; unyango olungaphezulu; ubume besakhiwo; ukhetho lweoli yokuthambisa kunye nezongezo; i-deformation ye-cylinder liner kunye nepiston ngenxa yokushisa ngexesha lokudibanisa kunye nokusebenza.
Ukunxitywa kweringi ye-piston kunokohlulwa ibe kukunxiba okuqhelekileyo, imikrwelo kunye ne-abrasions, kodwa ezi zinto zokunxiba aziyi kwenzeka zodwa, kwaye ziya kwenzeka ngaxeshanye, kwaye ziya kuchaphazela ngaxeshanye. Ngokubanzi, ukunxitywa komphezulu wokutyibilika mkhulu kuneendawo zokunxiba eziphezulu nezisezantsi. I-sliding surface iyona nto yokugqoka i-abrasives, ngelixa ukugqoka okuphezulu kunye nezantsi kubangelwa ukunyakaza okuphindaphindiweyo. Nangona kunjalo, ukuba ipiston ayiqhelekanga, inokonakala kwaye inxibe.
