Ipaki y'umukandara w'impeta ya piston y'imodoka ni iyihe?
Gupfunyika umukandara w'impeta ya piston mu modoka akenshi bivuga gushyira impeta ya piston mu gikoresho runaka gipfunyikamo kugira ngo ikingire kwangirika no koroshya gutwara no kubika. Uburyo busanzwe bwo gupfunyikamo burimo gupfunyika mu mifuka ya pulasitiki, gupfunyika mu ikarito no gupfunyika mu gasanduku k'icyuma.
Uburyo busanzwe bwo gupfunyika n'imiterere yabwo
Gupfunyika mu mashashi ya pulasitiki: Ubwo bwoko bw'ipfunyika buroroshye, bufata umwanya muto, bushobora gukumira ingese y'impeta ya pisitoni. Ariko, impeta ya pisitoni y'ishashi ya pulasitiki ubusanzwe ntabwo ari nziza, kandi bamwe mu bakora imashini bapfunyika inyuma n'agasanduku k'impapuro cyangwa impapuro z'ubudodo.
Gupakira mu gakarito: Isura y'agakarito ni nziza, yoroshye kuyifata, ishobora gushyirwaho ikimenyetso cyoroshye. Mbere yo gupakira, bamwe mu bakora batera irangi rirwanya ogisijeni ku buso bw'impeta ya piston kugira ngo yongere igihe cyo kuyikoresha. Gupakira mu gakarito bishobora no kuba ipfunyika ry'impeta ya piston kugira ngo hirindwe gukururana.
Gupakira mu gasanduku k'icyuma: ubusanzwe hakoreshwa icyuma gipakira, ubwo bwoko bw'igipakira buhanitse kandi budashobora gupfuka, bushobora gukuraho ubushuhe neza, bukarinda impeta ya piston.
Amakuru y'ibanze yerekeye impeta za piston
Impeta ya piston ishyirwa mu mwobo wa piston imbere mu mpeta y'icyuma, igabuwemo impeta yo gukanda n'impeta y'amavuta ebyiri. Impeta yo gukanda ikoreshwa mu gufunga uruvange rushobora gushya mu cyumba cyo gutwika, mu gihe impeta y'amavuta ikoreshwa mu gukurura amavuta arenze kuri silinda. Impeta ya piston ni ubwoko bw'impeta y'icyuma ifite ubugari bunini bwo kwaguka inyuma, bitewe n'itandukaniro ry'umuvuduko wa gaze cyangwa amazi kugira ngo habeho agafunga hagati y'uruziga rw'inyuma rw'impeta na silinda, no hagati y'impeta n'umuyoboro w'impeta .
Ingamba zo gushyiraho impeta ya piston y'imodoka zirimo ibi bikurikira:
Menya neza ko impeta ya piston ishyizwe neza mu gice cy'icyuma gifunganye, kandi ubike umwanya ukwiye wo gufungura aho uhurira, ukaba usabwa kugenzurwa hagati ya mm 0.06-0.10. Ibi bishobora gutuma impeta ya piston idatera kwangirika no kwangirika cyane bitewe n'aho idafite umwanya munini cyane.
Impeta ya piston igomba gushyirwaho neza kuri piston, kandi ikareba neza ko hari umwanya ukwiye ku ruhande ku burebure bw'umuyoboro w'impeta, byasabwa kugumana hagati ya mm 0.10-0.15. Ibi bishobora gutuma impeta ya piston idahagarara bitewe n'icyuho gito cyane cyangwa amazi aturuka bitewe n'icyuho kinini cyane.
Impeta ya chrome igomba gushyirwaho neza mu mwanya wa mbere, kandi aho ipfundo rigomba kuba ritanye neza n'aho umuyoboro w'amashanyarazi uturuka hejuru ya piston. Ibi bizagabanya kwangirika no gucika ku kazi.
Imyenge y'impeta za piston igomba kuba izunguruka kuri dogere 120 uvuye kuri imwe kandi ntigomba kuba ijyanye n'imyobo y'impeta za piston. Ibi birinda guhinda no kwangirika kw'impeta ya piston mu gihe cyo gukora .
Mu gushyiraho impeta ya piston y’igice cya koni, isura ya koni igomba kureba hejuru . Mu gushyiraho impeta ya torsion, chamfer cyangwa groove bigomba no kureba hejuru. Mu gushyiraho impeta ivanze, banza ushyireho impeta y’uruziga, hanyuma hakurikireho impeta irambuye n’impeta ya corrugated, kandi imyobo ya buri mpeta igomba kuba izungurutse .
Mu gihe cyo gushyiraho, komeza gusukura ubuso buhuza hagati y'impeta ya piston n'umuyoboro wa silindiri kugira ngo wirinde ko umwanda n'umwanda byavamo. Nyuma yo gushyiraho, reba niba ubuso buhuza hagati y'impeta ya piston n'umuyoboro wa silindiri bungana kugira ngo budapfukirana cyane cyangwa bufunganye cyane.
Koresha ibikoresho byihariye mu gushyiraho , nk'udupira twihariye two guteranya impeta za piston, amaboko y'udupira, nibindi. Ibi bigabanya ibyago byo kwangirika cyangwa kwangirika kw'impeta ya piston bitewe no kwaguka cyane .
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
Zhuo Meng Shanghai Auto Co, Ltd. yiyemeje kugurisha ibice by'imodoka bya MG&750 irahari kugura.
