Ayini ama-piston rings
Amasongo e-piston ayizindandatho zensimbi ezifakwe emihosheni ye-piston. Njengezingxenye eziyinhloko zenjini, enza imisebenzi efana nokuvala, ukudlulisa ukushisa, kanye nokuklwebha uwoyela. Ahlukaniswe ngezinhlobo ezimbili: izindandatho zegesi kanye nezindandatho zikawoyela.
Incazelo ye-Youdaoplaceholder0 kanye nomsebenzi wamasongo e-piston
Izindandatho zepiston ziyizingxenye zensimbi ezimise okwendandatho ezifakwe emihosheni yepiston. Imisebenzi yazo eyinhloko ihlanganisa:
Umsebenzi wokuvala we-Youdaoplaceholder0: Ukuvimbela igesi enomfutho ophezulu ekamelweni lokushisa ukuthi ingangeni ku-crankcase, ukuqinisekisa ukuthi injini isebenza kahle.
Umphumela wokudlulisa ukushisa we-Youdaoplaceholder0 : Ukushisa okumuncwa ngenhla kwe-piston kuqondiswa odongeni lwesilinda bese kuhlakazeka ohlelweni lokupholisa.
I-Youdaoplaceholder0 Ukuklwebha uwoyela kanye nokusatshalaliswa kwawoyela : Indandatho yamafutha inesibopho sokuklwebha uwoyela owengeziwe odongeni lwesilinda bese kwakheka ifilimu yamafutha efanayo ukunciphisa ukungqubuzana nokuguguleka.
Isakhiwo kanye nokuhlukaniswa kwe-Youdaoplaceholder0
Indandatho yegesi ye-Youdaoplaceholder0 (indandatho yokuvala) :
Ngokuvamile itholakala emihosheni yokuqala neyesibili ye-piston futhi ivala kakhulu igesi yokushisa.
Izinto zokwakha kufanele zibe nokumelana nokushisa okuphezulu kanye namandla aphezulu, njengensimbi ehlanganisiwe noma insimbi ehlanganisiwe.
Indandatho yamafutha ye-Youdaoplaceholder0 :
Itholakala emseleni wesithathu wendandatho, uwoyela wenjini owengeziwe utholakala ngembobo yokuklwebha uwoyela ukuvimbela isenzakalo "sokusha uwoyela".
Indawo yokusebenza kanye nezakhiwo zezinto ezibonakalayo
Izindandatho zepiston zisebenza ngaphansi kwezimo zokungqubuzana ezishisa kakhulu, ezicindezela kakhulu kanye nezisheshayo futhi zidinga ukuhlangabezana nezidingo ezilandelayo:
Inokuguquguquka okuhle futhi iqinisekisa ukulingana kahle nodonga lwesilinda.
Inokumelana okukhulu nokuguguleka ukuze ibhekane nokungqubuzana okushelelayo kwesikhathi eside.
Inamandla okumelana nokushisa futhi ingavimbela ukuguguleka kanye nokwehluleka emazingeni okushisa aphezulu.
Imisebenzi eyinhloko yendandatho yepiston ifaka phakathi ukuvala igesi yokushisa, ukulawula ifilimu kawoyela wokugcoba, ukuqhuba ukushisa nokusekela ukunyakaza kwepiston. Kuyingxenye eyinhloko yokusebenza okuzinzile kwezinjini zokushisa zangaphakathi.
Umsebenzi oyinhloko wendandatho ye-piston ngu-
Umphumela wokuvala we-Youdaoplaceholder0 .
Ukuvimbela igesi yokushisa okuphezulu kanye nengcindezi ephezulu ekamelweni lokushisa ukuthi ingangeni ekhabetheni lomshini wokushisa nokuqinisekisa ukusebenza kahle kokucindezela kanye nokushaya kwamandla (umsebenzi oyinhloko wendandatho yegesi).
Vimbela uwoyela wenjini ukuthi ungangeni ekamelweni lokushisa ngesikhala esiphakathi kwepiston nesilinda ukuze uhlanganyele ekushiseni (umsebenzi wokusiza wendandatho kawoyela).
Umphumela wokulawula uwoyela we-Youdaoplaceholder0 .
Indandatho kawoyela, ngesakhiwo esiklanywe ngokukhethekile, ikhuhla uwoyela wenjini owengeziwe odongeni lwesilinda, inciphisa ukusetshenziswa kukawoyela kanye nokwakheka kwamadiphozithi ekhabhoni.
Ngesikhathi esifanayo, kwakheka ifilimu kawoyela efanayo odongeni lwesilinda ukuqinisekisa umphumela wokugcoba phakathi kwepiston nesilinda.
Umphumela wokuqhuba ukushisa we-Youdaoplaceholder0 .
Cishe u-70% kuya ku-80% wokushisa okumuncwa yikhanda le-piston kuqhutshwa odongeni lwesilinda bese kuhlakazwa ohlelweni lokupholisa ukuze kuvinjelwe i-piston ekushiseni ngokweqile nasekuguquguqukeni.
Umphumela wokusekela we-Youdaoplaceholder0 .
Nciphisa ukumelana kokungqubuzana phakathi kwepiston nodonga lwesilinda ukuze kulondolozwe ukuzinza kokunyakaza okuqondile kwepiston.
Vimbela ukuguguleka okungavamile okubangelwa ukuthintana okuqondile phakathi kwepiston nodonga lwesilinda (okwaziwa ngokuthi "ukungqongqoza").
Indlela yokusebenzisa umsebenzi
Idizayini yebhalansi yokucindezela ye-Youdaoplaceholder0: Ukuvalwa okunamandla kutholakala ngokuhlanganiswa kwengcindezi yegesi kanye namandla okunwebeka, okugcina ukuvalwa okusebenzayo ngisho noma kwenzeka ukuguguleka.
Inhlanganisela ye-Youdaoplaceholder0 enezindandatho eziningi : Isakhiwo esijwayelekile siqukethe izindandatho zegesi ezimbili kanye nendandatho kawoyela eyodwa, ngokulandelana egxile ekuvalelweni kwegesi kanye nokulawulwa kwefilimu kawoyela.
Ubuchwepheshe bokwelapha ubuso be-Youdaoplaceholder0: Thuthukisa ukumelana nokuguguleka futhi wandise impilo yesevisi ngokusebenzisa izinqubo ezifana ne-chromium plating kanye ne-nitriding.
Amaphutha endandatho yepiston abonakala kakhulu njengokushiswa kukawoyela wenjini (njengomusi oluhlaza okwesibhakabhaka ophuma epayipini lokukhipha umoya), ukwanda okungavamile kokusetshenziswa kukaphethiloli, ukwehla kwamandla kanye nokwehluleka kokuvala isilinda, njll. Kubangelwa kakhulu ukuvimba kwamadiphozithi ekhabhoni, ukuguguleka noma ukufakwa okungalungile. Ukuxilongwa kochwepheshe kanye nokuphathwa ngesikhathi kuyadingeka ukuze kugwenywe umonakalo omkhulu wenjini.
I-Youdaoplaceholder0 Izehlakalo ezivamile zephutha
Ukwehluleka kwendandatho yepiston kuvame ukuholela kulezi zimpawu ezilandelayo ezibonakalayo:
I-Youdaoplaceholder0 Isenzakalo sokushiswa kwamafutha : intuthu eluhlaza okwesibhakabhaka iphuma epayipini lokukhipha umoya, futhi ukusetshenziswa kwamafutha kuyanda ngendlela engavamile (isibonelo, ngaphezu kwamalitha angu-0.5 ngamakhilomitha ayi-1,000).
Ukwehla kokusebenza kwe-Youdaoplaceholder0: Amandla enjini abuthakathaka, ukusheshisa okubuthakathaka, okuhambisana nokwenyuka kuka-30%-50% kokusetshenziswa kukaphethiloli.
I-Youdaoplaceholder0 Ukungasebenzi kahle kwemishini : ukuvuza kwesilinda kubangela ukwanda kwezinga lokushisa lokukhipha umoya, izinga lokushisa lamanzi elingavamile ku-liner yesilinda, noma umsindo nokudlidliza okungavamile.
Ukuhlaziywa kwezimbangela eziyinhloko ze-
Izimbangela eziyinhloko zokwehluleka zifaka:
I-Youdaoplaceholder0 Ukuvaleka kwediphozithi yekhabhoni : Ukusetshenziswa kwesikhathi eside kukaphethiloli ophansi noma ukushayela ibanga elifushane kungabangela ukuthi idiphozithi yekhabhoni ibhajwe ezikhaleni zamasongo e-piston, okubangela u-60% kuya ku-70% wamacala amaphutha, okuvumela uwoyela wenjini ukuthi ungene ekamelweni lokushisa bese usha.
I-Youdaoplaceholder0 Ukuguguleka noma ukuphuka kwendandatho yepiston : Ukunakekelwa okungalungile kwesihlungi somoya kungenisa uthuli, okubangela ukuguguleka komsele wendandatho noma ukuphuka kokukhathala komzimba wendandatho, kunciphisa ukusebenza kokuvala.
Iphutha lokufakwa noma lokuklama le-Youdaoplaceholder0:
Isikhala sokuvuleka kwendandatho yepiston sincane kakhulu, futhi sibhajwa kusilinda ngemva kokwandiswa kokushisa.
Ukugoba kwenduku yokuxhuma kubangela ukuthi i-piston ithambe ngesikhathi sokusebenza, okuholela ekugugeni okungalingani.
Izindlela zokuxilonga nezokuhlola ze-Youdaoplaceholder0
Ukuxilongwa okuqinisekisiwe kudinga inhlanganisela yezindlela zobungcweti:
I-Youdaoplaceholder0 Ukuqaphela kokuqala : Qopha ukusetshenziswa kukawoyela bese uhlola ukuthi intuthu eluhlaza okwesibhakabhaka noma igesi yokukhipha umoya evuthayo ikhishwa yini ngesikhathi sokuqala okubandayo.
Ukutholwa kwethuluzi le-Youdaoplaceholder0 :
Ukuhlolwa kwe-endoscopic kwama-carbon deposits odongeni lwesilinda noma ukujikijela kwendandatho ye-piston.
Linganisa inani lokucindezela kwesilinda (ngokuvamile kufanele libe ngaphezu kwamabha ayi-10). Uma liphansi, libonisa ukuthi uphawu luhlulekile.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
