Iyini iphakheji yebhande leringi yemoto yepiston
Ukupakishwa kwebhande lendandatho yepiston yezimoto ngokuvamile kubhekisela ekubekeni indandatho yepiston esitsheni esithile sokupakisha ukuyivikela emonakalweni nokwenza lula ukuhamba nokugcinwa. Izindlela zokupakisha ezijwayelekile zifaka ukupakishwa kwezikhwama zepulasitiki, ukupakishwa kwamabhokisi namabhokisi ensimbi.
Izindlela zokupakisha ezijwayelekile nezici zazo
Ukupakishwa kwezikhwama zepulasitiki : Lolu hlobo lokupakisha lulula, luthatha indawo encane, lungavimbela ngempumelelo ukugqwala kweringi yepiston. Kodwa-ke, indandatho ye-piston yesikhwama sepulasitiki ngokuvamile ayinhle, futhi abanye abakhiqizi bazovala ingaphandle ngebhokisi lephepha noma iphepha le-kraft .
ukupakishwa kwebhokisi : ukubukeka kwebhokisi kuhle, kulula ukuphatha, kungamakwa kalula. Ngaphambi kokupakisha, abanye abakhiqizi bazophinde bafafaze i-anti-oxidation coating phezu kweringi ye-piston ukuze bandise impilo yayo yesevisi. Ukupakishwa kwebhokisi kungase futhi kube ukupakishwa kwesibili kweringi ye-piston ukuvimbela ukungqubuzana.
ukupakishwa kwebhokisi lensimbi : ngokuvamile ukukhiqizwa kwe-tinplate, lolu hlobo lokupakisha olusezingeni eliphezulu nobufakazi bomswakama, lungahlukanisa ngempumelelo umswakama, luvikele indandatho yepiston.
Ulwazi oluyisisekelo mayelana namasongo e-piston
Indandatho ye-piston ishumekwe emseleni we-piston ngaphakathi kwendandatho yensimbi, ihlukaniswe yaba indandatho yokucindezela kanye nendandatho kawoyela ezimbili. Indandatho yokucindezela isetshenziselwa ukuvala ingxube evuthayo ekamelweni elivuthayo, kuyilapho indandatho kawoyela isetshenziselwa ukukhuhla uwoyela oweqile kusilinda. Indandatho ye-piston iwuhlobo lwendandatho yensimbi enwebekayo enokuwohloka okukhulu okunwebekayo kwangaphandle, okuncike kumehluko wengcindezi yegesi noma uketshezi ukuze kwakhe uphawu phakathi kwendilinga engaphandle yesiyingi nesilinda, naphakathi kweringi negroove eyindandatho.
Izinyathelo zokuphepha zokufakwa kwe-piston yezimoto zihlanganisa izici ezilandelayo:
Qinisekisa ukuthi iringi ye-piston ibekwe kahle kusilinda liner, futhi ugcine indawo efanelekile yokuvula endaweni okusebenzela kuyo, okutuswa ukuthi ilawulwe kububanzi obungu-0.06-0.10mm. Lokhu kungaqinisekisa ukuthi iringi ye-piston ngeke ikhiqize ukungqubuzana nokuguga okukhulu ngenxa yokucaciswa okuncane kakhulu.
Iringi ye-piston kufanele igxunyekwe ngendlela efanele ku-piston, futhi kuqinisekiswe ukuthi kukhona indawo ekahle engaseceleni eduze nokuphakama kwe-groove yeringi, okutuswa ukuba igcinwe iphakathi kuka-0.10-0.15mm. Lokhu kungaqinisekisa ukuthi iringi yepiston ngeke igxumeke ngenxa yegebe elincane kakhulu noma ukuvuza ngenxa yegebe elikhulu kakhulu.
Iringi ye-chrome izofakwa ngokukhethayo endaweni yokuqala, futhi ukuvuleka akufanele kubhekane ngqo nomgodi wamanje we-eddy ongaphezulu kwepiston. Lokhu kuzonciphisa ukuguga nokuguga emsebenzini.
Izimbobo zamasongo e-piston zizonyakaziswa ngama-degree angu-120 ukusuka kwelinye futhi akumele ziqondaniswe nezimbobo zephini le-piston . Lokhu kuvimbela ukudlidliza kanye nokuguga okwengeziwe kweringi ye-piston phakathi nokusebenza.
Lapho ufaka iringi yepiston yesigaba sekhoni, ubuso bekhoni kufanele bubheke phezulu. Ukuze kufakwe indandatho ye-torsion, i-chamfer noma i-groove kufanele ibheke phezulu. Lapho ufaka indandatho yenhlanganisela, faka iringi ye-axial yokuqala, kulandele iringi eyisicaba kanye neringi likathayela, futhi izimbobo zeringi ngayinye kufanele zinyakaze.
Ngesikhathi sokufakwa, gcina indawo yokuxhumana phakathi kweringi yepiston ne-cylinder liner ihlanzekile ukuze uvimbele ukuphazamiseka kokungcola nokungcola. Ngemva kokufaka, hlola ukuthi ingabe indawo yokuxhumana phakathi kweringi yepiston kanye ne-cylinder liner ifakwe ngokulinganayo ukugwema ukuxega kakhulu noma ukucinana kakhulu.
Sebenzisa amathuluzi akhethekile ukuze ufake , njengephinifa lokuhlanganisa elikhethekile lamasongo e-piston, imikhono yekhoni, njll. Lokhu kunciphisa ubungozi bokonakala kweringi noma ukukhubazeka ngenxa yokwanda ngokweqile.
