Nkewa piston:
Ebe ọ bụ na pistons nke engine combustion n'ime na-arụ ọrụ n'okpuru okpomọkụ dị elu, nrụgide dị elu na ọnọdụ ibu dị elu, ihe ndị a chọrọ maka pistons dị elu, n'ihi ya, anyị na-ekwukarị banyere nhazi nke pistons ọkụ ọkụ.
1. Dị ka mmanụ ụgbọala e ji mee ihe si dị, a pụrụ ikewa ya gaa na pistons engine petrol, piston engine diesel, na piston gas gas.
2. Dị ka ihe onwunwe nke piston si dị, ọ nwere ike kewaa n'ime nkedo ígwè piston, ígwè piston, aluminum alloy piston na piston jikọtara.
3. Dị ka usoro n'ichepụta piston oghere, ọ nwere ike kewaa n'ime ike ndọda piston, piakota nkedo piston na forging piston.
4. Dị ka ọnọdụ ọrụ nke piston si dị, enwere ike kewaa ya ụzọ abụọ: piston na-enweghị nrụgide na piston na-arụ ọrụ.
5. Dị ka ojiji nke pistons, ọ nwere ike ikewa n'ime ụgbọ ala pistons, gwongworo pistons, ọgba tum tum pistons, mmiri pistons, tank pistons, traktọ pistons, lawnmower pistons, wdg.
Achọrọ nka na ụzụ:
1. A ghaghị inwe ike zuru oke, isi ike, obere uka na ịdị arọ dị arọ iji hụ na ike kachasị nta.
2. Ezi conductivity thermal, oke okpomọkụ na-eguzogide, nrụgide dị elu, nkwụsị nke corrosion, ikike ikpo ọkụ zuru oke, na obere ebe kpo oku.
3. Ekwesịrị inwe obere ọnụọgụ esemokwu n'etiti piston na mgbidi piston.
4. Mgbe okpomọkụ na-agbanwe, nha na mgbanwe ọdịdị kwesịrị ịdị ntakịrị, na obere oghere kwesịrị ịnọgide na-enwe mgbidi cylinder.
5. Ọnụ ọgụgụ mgbasawanye nke thermal dị ntakịrị, nnukwu ike ndọda dị ntakịrị, ọ na-enwekwa mbelata uwe dị mma na ike ọkụ.
Ọnọdụ ọrụ:
Piston na-arụ ọrụ n'okpuru ọnọdụ okpomọkụ dị elu, nrụgide dị elu, oke ọsọ na mma mmanu na-adịghị mma.Piston na-akpakọrịta ozugbo na gas na-ekpo ọkụ dị elu, na ọnọdụ okpomọkụ ozugbo nwere ike iru karịa 2500K.Ya mere, ikpo ọkụ ahụ dị njọ na ọnọdụ ikpo ọkụ ọkụ dị nnọọ njọ, ya mere, okpomọkụ nke piston dị oke elu n'oge ọrụ, n'elu dị elu dị ka 600-700K, na nkesa okpomọkụ na-adịghị mma;A na-edobe elu nke piston na nrụgide gas dị nnọọ ukwuu, karịsịa nrụgide ọrịa strok na-arụ ọrụ bụ nke kasị ukwuu, mmanụ ụgbọala engine dị elu dị ka 3-5MPa, na mmanụ dizel dị elu dị ka 6-9MPa, nke na-eme ka ọ dị elu. piston na-emepụta mmetụta ma na-enwe mmetụta nke nrụgide n'akụkụ;~ 12m / s) na-emegharị mmegharị ahụ, na ọsọ na-agbanwe mgbe niile, nke na-emepụta ike dị ukwuu nke na-adịghị ike, nke na-eme ka piston dị n'okpuru nnukwu ibu ọzọ.Mgbe piston na-arụ ọrụ n'okpuru ọnọdụ ndị dị otú ahụ siri ike, ọ ga-emeziwanye ma mee ka ọ dịkwuo mma, ọ ga-ebutekwa ibu ọzọ na nrụgide okpomọkụ, n'otu oge ahụ, gas ga-emebi ya na kemịkal.
Nyochaa piston bụ nleba anya dayameta sket, piston mgbanaka groove elu na nha oghere oche piston:
① A ga-ekpebi nhọrọ nke piston dị ka nha nrụzi nke cylinder ahụ.Ọtụtụ mgbe, a na-akara ọnụ ahịa nha nha n'elu piston;
② N'otu usoro nke ndị na-azụ azụ azụ, nhazi nke pistons abụghị otu.Ya mere, mgbe ị na-azụta pistons, a ga-ahọrọ ụdị pistons kwekọrọ dịka ụdị engine si dị.N'otu engine ahụ, otu ika, otu ìgwè ma ọ bụ Pistons nwere otu koodu ngwaahịa;Otu ihe nlereanya ahụ ga-eji pistons nwere otu koodu ngwaahịa ahụ iji hụ na ọdịiche dị na dayameta na ịdị mma nke piston adịghị agafe oke nke ụlọ ọrụ mbụ ahụ akọwapụtara.Ma ọ bụghị ya, ọ ga-eme ka injin ahụ na-ere ọkụ nke ukwuu, na-arụ ọrụ siri ike, ma belata akụ na ụba na ike..Ya mere, mgbe ị na-ahọrọ pistons, a ga-ahọrọ ụdị piston kwekọrọ dịka ụdị engine si dị.
