Menene taron piston ya ƙunshi?
Ƙungiyar piston wani muhimmin sashi ne na injin mota, wanda akasari ya ƙunshi abubuwa shida masu zuwa:
1. Piston: Yana daga cikin ɗakin konewa kuma an sanye shi da ramukan zobe da yawa don shigar da zoben piston.
2. Piston zobe: Ana sanya shi a kan piston don rufewa, yawanci yana kunshe da zoben gas da zoben mai.
3. Piston fil: Haɗa piston da ƙaramin shugaban sandar haɗin piston, akwai hanyoyi guda biyu na cikakken iyo da Semi- iyo.
4. Piston haɗa sanda: haɗa sandar piston da crankshaft, raba zuwa babban kai da ƙaramin kai a bangarorin biyu, ƙaramin kai da aka haɗa da piston, babban kai mai haɗawa da crankshaft.
5. Connecting sanda bearing: wani bangaren mai mai da aka sanya a cikin babban kan sandar haɗi.
6. Haɗin sandar ƙugiya: ƙulli wanda ke gyara babban ƙarshen sandar haɗawa akan crankshaft.
Zoben Piston shine ainihin abin da ke cikin injin mai, shi da Silinda, piston, bangon Silinda tare don kammala hatimin iskar gas. Injunan motoci da aka fi amfani da su suna da injunan diesel da man fetur iri biyu, saboda aikin mai daban-daban, amfani da zoben fistan ba iri daya ba ne, zoben fistan na farko ana yin su ne ta hanyar simintin gyaran fuska, amma tare da ci gaban fasaha, karfe mai karfin gaske. An haifi zoben fistan, kuma tare da aikin injin, bukatun muhalli suna ci gaba da ingantawa, aikace-aikacen jiyya iri-iri na ci gaba, irin su spraying thermal, electroplating, chrome plating, da dai sauransu. Gas nitriding, jigon jiki, shafi na sama, zinc manganese. phosphating magani, da dai sauransu, ƙwarai inganta aikin piston zobe.
Ana amfani da fil ɗin piston don haɗa piston zuwa sandar haɗi kuma ya wuce ƙarfin kan piston zuwa sandar haɗi ko akasin haka.
Piston fil yana fuskantar babban nauyin tasiri na lokaci-lokaci a ƙarƙashin yanayin zafi mai zafi, kuma saboda kusurwar juyawa na piston fil a cikin ramin fil ba shi da girma, yana da wuya a samar da fim mai lubricating, don haka yanayin lubrication ba shi da kyau.
