Chii chinonzi piston yemotokari
Pistoni yemotokari ndiyo chikamu chinofamba mukati meinjini yekupisa mukati iyo inoshandura simba rekupisa kuita simba remakanika. Inotumira kumanikidzwa kwekupiswa ku crankshaft kuburikidza nekufamba kunodzokororwa uye inobatsira mukuumbwa kwekamuri rekupiswa.
Youdaoplaceholder0 Tsanangudzo huru nemabasa
Pistoni yemota chinhu chakaita se cylindrical chakaiswa mukati me cylinder yeinjini. Mabasa ayo makuru anosanganisira:
Youdaoplaceholder0 Kushandurwa kwesimba : Kumanikidzwa kwegasi kunokonzerwa nekupiswa kwemafuta kunoendeswa ku crankshaft kuburikidza nepiston pin ne connecting rod, zvichiita kuti ive simba rinotenderera.
Youdaoplaceholder0 Kuumbwa kwekamuri rinopisa : Pamwe chete nemusoro wesirinji nemadziro esinji, zvinoumba nzvimbo yakavharwa yekutsva.
Youdaoplaceholder0 Kurongeka kwemafambiro : Kutenderera kwematanho mana ekupinda, kudzvanya, kugadzira simba uye kuburitsa mweya kunoitwa kuburikidza nekubatanidzwa kwemafambiro anodzokororwa.
Youdaoplaceholder0 Maumbirwo uye zvinhu zvemukati
Pistoni inoshandisa dhizaini yakapatsanurwa:
Youdaoplaceholder0 top : Dzichitakura zvakananga simba rekupisa, mainjini epeturu anowanzova nechimiro chepamusoro chakati sandara, nepo mainjini edhiziri anowanzo kugadzirwa nemakomba kuti asvike pazvinodiwa pakupisa.
Musoro weYoudaoplaceholder0: Chikamu chakakosha chekuisa mapiston rings, ane ma ring grooves matatu kusvika mana (gas rings nemafuta rings) kuti avharwe uye atsvedze.
Siketi yeYoudaoplaceholder0 : Inoshanda zvakanaka, kufukidza pamusoro kunoderedza kukweshana, dhizaini yemazuva ano inowanzova "pfupi uye yakakora" kuti iwedzere kuomarara uye kupisa kusapera.
Chinhu chikuru ialuminium alloy, iyo inosanganisa yakareruka (inoderedza simba remagetsi) uye kuramba kupisa kwakanyanya. Mamwe mamodheru anoshanda zvakanyanya anoshandisa nickel plating kana ceramic coating
Youdaoplaceholder0 Nzvimbo yebasa nematambudziko ehunyanzvi
Piston dzinoshanda mumamiriro ezvinhu akaipisisa:
Youdaoplaceholder0 Tembiricha yepamusoro uye kumanikidzwa kwakanyanya : Tembiricha yekamera yekupisa inodarika 2500K, uye pamusoro payo panoramba paine kumanikidzwa kwe3-9MPa.
Youdaoplaceholder0 kufamba kwekumhanya kwepamusoro: Injini yepeturu inogona kusvika kumhanya kwekutenderera kwe6000rpm, zvichienderana nekumhanya kwakatsetseka kunodarika 20m/s.
Youdaoplaceholder0 Masimba akaomarara : anosangana nemitoro inokonzereswa nguva nenguva, kumanikidzwa kwedivi uye kushanduka kwekupisa.
Mapistoni emazuva ano anovandudza chimiro chawo kuburikidza nekuongorora zvinhu zvishoma uye anoshandisa hunyanzvi hwetekinoroji hwakadai senzira dzemafuta anotonhorera uye machira ekudzivirira kupisa kuti agadzirise matambudziko aya.
Pistoni yese inogona kukamurwa kuita zvikamu zvitatu: pamusoro pepistoni, musoro wepistoni uye siketi yepistoni.
Basa guru repiston nderekutakura kumanikidzwa kwekupiswa kuri musirindiri uye kuendesa simba iri ku crankshaft kuburikidza nepini yepiston netsvimbo yekubatanidza. Pamusoro pezvo, piston, pamwe chete nemusoro wesirindiri nemadziro esirindiri, zvinoumba imba yekupiswa.
Pamusoro pepiston chikamu chekamuri rinopisa uye rinowanzogadzirwa mumhando dzakasiyana. Muinjini dzepeturu, pamusoro pepiston unonyanya kushandisa pamusoro wakatsetseka kana pamusoro wakakombama kuti chimiro chekamuri rinopisa chive chidiki, nzvimbo yekudzima kupisa ive diki, uye maitiro ekugadzira ave nyore. Mapiston epamusoro eConvex anowanzo shandiswa muinjini dzepeturu dzine stroke mbiri. Pamusoro pepiston yeinjini yedhiziri unowanzo gadzirwa kuita makomba akasiyana-siyana.
Musoro wepiston ndiwo chikamu chiri pamusoro pechigaro chepiston pin. Mhete dzepiston dzinoiswa pamusoro pepiston kudzivirira gasi rinopisa zvakanyanya uye rinodzvinyirira zvakanyanya kuti risapinde mucrankcase uye kudzivirira mafuta einjini kuti asapinde mukamuri rinopisa. Kupisa kwakawanda kunotorwa nepamusoro pepiston kunoendeswawo kucylinder kuburikidza nemusoro wepiston uye kunozotakurwa nechinhu chinotonhodza.
Musoro wepiston wakagadzirwa nema ring grooves akati wandei ekuisa ma piston rings. Huwandu hwema piston rings hunoenderana nezvinodiwa zve sealing uye hunoenderana nekumhanya kweinjini uye kumanikidzwa kwe cylinder. Huwandu hwema rings muinjini inomhanya zvakanyanya hushoma pane huri muinjini inomhanya zvishoma, uye huwandu hwema rings muinjini ye petrol hushoma pane huri muinjini ye dizeli. Injini ye petrol inoshandisa ma gas rings maviri ne oil ring imwe. Injini ye dizeli ine ma gas rings matatu ne oil ring imwe. Injini dze dizeli dzinomhanya zvishoma dzinoshandisa ma gas rings matatu kusvika mana. Kuti kuderedza kurasikirwa kwekukweshana, kukwirira kwe annular part kunofanira kudzikiswa zvakanyanya sezvinobvira. Pachinzvimbo chekuona kuti yakavharwa, kuedza kunofanira kuitwa kuderedza huwandu hwema rings.
Zvikamu zvese zviri pasi pemugero wepiston zvinonzi masiketi episton. Basa rayo nderekutungamira piston kuti iite kufamba kunodzokororwa mu cylinder uye kutakura kumanikidzwa kwedivi. Kana injini ichishanda, nekuda kwesimba remhepo mukati me cylinder, piston inokotama uye inoshanduka. Mushure mekunge piston yapiswa, nekuti pane simbi yakawanda pa piston pin, kukura kwayo kwakakura kupfuura kune zvimwe zvikamu. Pamusoro pezvo, piston ichagadziriswawo nekumanikidzwa pasi pesimba rekumanikidzwa kwedivi. Mugumisiro wakabatanidzwa wekushanduka uku kunoita kuti chikamu che piston skirt chive ellipse ine axis refu yakatarisana nekwakananga piston pin. Pamusoro pezvo, nekuda kwekupararira kusina kuenzana kwekushisa nehuremu pamwe chete ne axis ye piston, kuwedzera kwekupisa kwechikamu chimwe nechimwe che cross-section kwakakura kumusoro uye kudiki pasi.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
