Piston.
Piston ke motsamao o phetoang 'meleng oa silindara ea enjene ea koloi. Sebopeho sa motheo sa piston se ka aroloa ka holimo, hlooho le seaparo. Karolo e ka holimo ea piston ke karolo e ka sehloohong ea kamore ea mollo, 'me sebōpeho sa eona se amana le foromo e khethiloeng ea kamore ea mollo. Hangata lienjineri tsa peterole li sebelisa piston e bataletseng, e nang le monyetla oa sebaka se senyenyane sa ho monya mocheso. Hangata piston ea enjene ea diesel e na le likoti tse fapaneng, sebopeho sa eona se ikhethileng, boemo le boholo ba eona li tlameha ho ba le sebopeho sa motsoako oa enjene ea disele le litlhoko tsa ho tuka.
Bokaholimo ba piston ke karolo ea kamore e tukang, ka hona hangata e entsoe ka libopeho tse fapaneng, 'me piston ea enjene ea peterole hangata e sebelisa bokaholimo bo bataletseng kapa bokaholimo ba concave, e le hore kamore ea ho tuka e kopane, sebaka sa ho qhala mocheso se nyane. , 'me mokhoa oa ho etsa lihlahisoa o bonolo. Lipiston tsa hlooho tsa convex li sebelisoa hangata lienjineng tse peli tsa peterole. Litlhōrō tsa piston tsa enjine ea diesel hangata li entsoe ka likoti tse fapaneng.
Hlooho ea piston ke karolo e ka holimo ho setulo sa piston, 'me hlooho ea piston e kenngoa ka lesale la piston ho thibela mocheso o phahameng le khase e phahameng ea khatello ho kena ka har'a crankcase le ho thibela oli ho kena ka kamoreng ea mollo; Boholo ba mocheso o kenang ka holim'a piston o boetse o fetisetsoa ho cylinder ka hlooho ea piston, ebe o fetisetsoa ka mokhoa o pholileng.
Hlooho ea piston e sebetsoa ka li-grooves tse 'maloa bakeng sa mehele ea piston,' me palo ea mehele ea piston e itšetlehile ka litlhoko tsa tiiso, e amanang le lebelo la enjene le khatello ea cylinder. Lienjene tsa lebelo le phahameng li na le liringche tse fokolang ho feta lienjine tse lebelo le tlase, 'me lienjene tsa peterole li na le mehele e fokolang ho feta lienjine tsa disele. Lienjineri tse akaretsang tsa peterole li sebelisa mehele e 2 ea khase le lesale la oli le le leng; Enjene ea diesel e na le masale a 3 a khase le lesale la oli le le leng; Enjene ea diesel e lebelo e tlase e sebelisa mehele ea khase e 3 ~ 4. E le ho fokotsa tahlehelo ea likhohlano, bophahamo ba karolo ea lebanta bo lokela ho fokotsoa ka hohle kamoo ho ka khonehang, 'me palo ea mehele e lokela ho fokotsoa tlas'a boemo ba ho tiisa ho tiisa.
Likarolo tsohle tsa lesale la piston ka tlase ho groove li bitsoa li-skirts tsa piston. Mosebetsi oa eona ke ho tataisa piston ka silindara bakeng sa motsamao o phetoang le ho mamella khatello ea lehlakore. Ha enjene e sebetsa, ka lebaka la phello ea khatello ea khase ka silindara, piston e tla khumama le ho holofala. Ka mor'a hore piston e chese, palo ea katoloso e kholo ho feta ea libaka tse ling ka lebaka la tšepe ea piston. Ho phaella moo, piston e tla hlahisa deformation ea extrusion tlas'a ketso ea khatello ea lehlakore. Ka lebaka la deformation e ka holimo, karolo ea seaparo sa piston e fetoha ellipse ka lehlakoreng la axis e telele e pota-potileng piston ea piston. Ho phaella moo, ka lebaka la ho aroloa ho sa tšoaneng ha mocheso le boima ho latela axis ea piston, katoloso ea mocheso ea karolo ka 'ngoe e kholo ka holimo le e nyenyane ka tlase.
Liphoso tse kholo tsa kopano ea piston le lisosa tsa tsona ke tse latelang:
1. Ho tlosoa ha karolo e ka holimo ea piston. Piston ablation e hlaha ka holim'a piston, e nang le likoti tse hlephileng maemong a bobebe le ho qhibiliha ha lehae maemong a boima. Lebaka le ka sehloohong la ho tlosoa ha karolo e ka holimo ea piston e bakoa ke ho tuka ho sa tloaelehang, e le hore holimo ho amohele mocheso o mongata haholo kapa ho matha tlas'a mojaro o moholo ka mor'a hore lesale la piston le khomarele le ho robeha.
2, bokaholimo ba piston bo phunyeha. Tataiso ea ho petsoha ka holim'a piston hangata e tšoana le axis ea lesoba la piston, e bakoang haholo ke ho phatloha ha mokhathala ho bakoang ke khatello ea mocheso. Lebaka: ts'ebetso e feteletseng ea enjene e lebisa ho deformation e feteletseng ea piston, e bakang mokhathala o phatlohang holim'a piston;
3, piston ring groove side roar apare. Ha piston e ea holimo le tlase, selikalikoe sa piston se lokela ho ba radial telescopic le deformation ea cylinder, haholo-holo mocheso oa "ring groove" oa pele o phahame, 'me o angoa ke "tšusumetso" ea khase le lekhalo la oli, kahoo. ho ferekana ha selikalikoe le ho sisinyeha ho etsahala ka har'a groove ea lesale, ho baka ho senyeha;
4. Lesale la piston ke coke e khomaretsoeng ka har'a ring groove. Piston ring coking ke sephetho sa ho tlotsa oli oxidation deposition kapa tahlehelo ea lesale la tokoloho ea ho tsamaea ka tanka, ho hloleha hona ho kotsi haholo. Mabaka a ka sehloohong: enjene disele overheating kapa nako e telele overload mosebetsi, e le hore lubricating oli boka, piston reng, silindara tebileng mogote deformation; Tšilafalo ea oli e tlotsang e tebile, boleng ba oli e tlotsang bo fokola; Sesebelisoa sa crankcase ventilation ha se sebetse hantle, se baka khatello e feteletseng e mpe kapa moea o fokolang oa silindara, ho bakang ho potlaka ha oli. Ka hona, hoa hlokahala ho netefatsa tšebeliso ea oli e tšoanelehang ho thibela enjene ea dizeli ho chesa haholo.
Haeba u batla ho tseba haholoanyane, tsoela pele ho bala lingoliloeng tse ling sebakeng sena sa marang-rang!
Ka kopo, re letsetse haeba u hloka lihlahisoa tse joalo.
Zhuo Meng Shanghai Auto Co., Ltd. e ikemiselitse ho rekisa likarolo tsa koloi tsa MG&MAUXS tse amoheloang ho li reka.
