Kedu ihe bụ piston ụgbọ ala
Piston nke ụgbọala bụ akụkụ na-agagharị n'ime injin ọkụ dị n'ime nke na-agbanwe ike okpomọkụ ka ọ bụrụ ike igwe. Ọ na-ebufe nrụgide ọkụ na crankshaft site na mmegharị na-agbanwe agbanwe ma na-esonye na nhazi nke ụlọ ọkụ.
Nkọwa na ọrụ isi nke Youdaoplaceholder0
Piston ụgbọala bụ ihe dị ka silinda nke etinyere n'ime silinda injin. Isi ọrụ ya gụnyere:
Youdaoplaceholder0 Mgbanwe ike : A na-ebufe nrụgide gas nke ọkụ mmanụ na-akpata na crankshaft site na pin piston na mkpanaka njikọ, na-agbanwe ya ka ọ bụrụ ike ntụgharị.
Ihe mejupụtara ụlọ ọkụ nke Youdaoplaceholder0 : Ya na isi silinda na mgbidi silinda, ọ na-emepụta oghere ọkụ mechiri emechi.
Youdaoplaceholder0 Nhazi mmegharị : A na-emecha usoro ngafe anọ nke nnabata, mkpakọ, mmepụta ike na ikpochapu site na nhazi nke mmegharị na-agbanwe agbanwe.
Youdaoplaceholder0 Njirimara nhazi na ihe onwunwe
Piston ahụ nwere nhazi nkewa dị iche iche:
Youdaoplaceholder0 elu : N'ịbụ ndị na-ebu nrụgide ọkụ ozugbo, injin mmanụ ụgbọala na-ejikarị usoro dị larịị n'elu, ebe a na-emepụta injin dizel na olulu iji mezuo ihe achọrọ maka ọkụ.
Isi Youdaoplaceholder0 : Akụkụ dị mkpa maka itinye mgbanaka piston, nke nwere oghere mgbanaka 3 ruo 4 (mgbanaka gas na mgbanaka mmanụ) iji nweta mkpuchi na mmanụ.
Youdaoplaceholder0 Skirt : Ọrụ nduzi, mkpuchi elu na-ebelata esemokwu, imewe ọgbara ọhụrụ na-adịkarị "mkpụmkpụ ma sie ike" iji mee ka ike na mmịpụta okpomọkụ dịkwuo mma.
Isi ihe e ji eme ya bụ alloy aluminum, nke na-ejikọta ihe dị mfe (na-ebelata ike inertial) na iguzogide okpomọkụ dị elu. Ụfọdụ ụdị arụmọrụ dị elu na-eji nickel plating ma ọ bụ seramiiki
Youdaoplaceholder0 Ọnọdụ ọrụ na ihe ịma aka teknụzụ
Pistons na-arụ ọrụ n'ọnọdụ dị oke njọ:
Youdaoplaceholder0 Okpomọkụ dị elu na nrụgide dị elu : Okpomọkụ ozugbo nke ụlọ ọkụ gafere 2500K, elu ya na-ebukwa nrụgide nke 3-9MPa mgbe niile.
Youdaoplaceholder0 ngagharị ọsọ dị elu : Injin mmanụ ụgbọala nwere ike iru ọsọ ntụgharị nke 6000rpm, nke kwekọrọ na ọsọ kwụ ọtọ gafere 20m/s.
Youdaoplaceholder0 Ike dị mgbagwoju anya : a na-enwe ibu mmetụta oge, nrụgide akụkụ na mgbanwe nrụgide okpomọkụ.
Piston nke oge a na-eme ka nhazi ha ka mma site na nyocha ihe ndị nwere oke ma na-anabata ihe ọhụrụ teknụzụ dị ka ọwa mmanụ oyi na mkpuchi mkpuchi okpomọkụ iji dozie nsogbu ndị a.
A pụrụ kewaa piston ahụ dum ụzọ atọ: elu piston ahụ, isi piston ahụ na uwe mwụda piston ahụ.
Isi ọrụ nke piston bụ ibu nrụgide ọkụ dị na silinda wee bufee ike a na crankshaft site na pin piston na mkpanaka njikọ. Na mgbakwunye, piston ahụ, yana isi silinda na mgbidi silinda, na-emepụta ụlọ ọkụ.
Elu piston bụ akụkụ nke ụlọ ọkụ ma a na-emekarị ya n'ụdị dị iche iche. Na injin mmanụ ụgbọala, elu piston na-ejikarị elu dị larịị ma ọ bụ elu concave mee ka nhazi ụlọ ọkụ ahụ dị obere, ebe okpomọkụ na-apụ apụ dị obere, na usoro mmepụta ya dị mfe. A na-ejikarị pistons elu convex eme ihe na injin mmanụ ụgbọala nwere strok abụọ. A na-emekarị elu piston nke injin dizel ka ọ bụrụ olulu dị iche iche.
Isi piston bụ akụkụ dị n'elu oche piston pin. A na-etinye mgbaaka piston n'isi piston iji gbochie gas okpomọkụ dị elu na nrụgide dị elu ịbanye na crankcase na iji gbochie mmanụ injin ịbanye n'ime ụlọ ọkụ. A na-ebufekwa ọtụtụ okpomọkụ nke elu piston ahụ na silinda site na isi piston wee buru ya site na ihe na-ajụ oyi.
A na-eji ọtụtụ oghere mgbanaka eme isi piston ahụ maka itinye mgbanaka piston. Ọnụọgụ mgbanaka piston dabere na ihe achọrọ maka mkpuchi ma jikọtara ya na ọsọ injin na nrụgide silinda. Ọnụọgụ mgbanaka dị na injin ọsọ dị elu pere mpe karịa nke dị na injin ọsọ dị ala, ọnụọgụ mgbanaka dị na injin petrol petrol pere mpe karịa nke dị na injin dizel. Injin petrol nkịtị na-eji mgbanaka gas abụọ na otu mgbanaka mmanụ. Injin dizel nwere mgbanaka gas atọ na otu mgbanaka mmanụ. Injin dizel dị obere na-eji mgbaaka gas atọ ruo anọ. Iji belata mfu esemokwu, a ga-ebelata elu nke akụkụ annular dịka o kwere mee. N'ọnọdụ nke ijide n'aka na mkpuchi, a ga-eme mgbalị iji belata ọnụọgụ mgbaaka.
A na-akpọ akụkụ niile dị n'okpuru oghere mgbanaka piston uwe mwụda piston uwe mwụda piston. Ọrụ ya bụ iduzi piston ahụ ka ọ na-emegharị mmegharị na silinda ma na-ebu nrụgide n'akụkụ. Mgbe injin ahụ na-agba ọsọ, n'ihi mmetụta nke nrụgide gas dị n'ime silinda ahụ, piston ahụ ga-agbagọ ma gbanwee. Mgbe emechara ka piston ahụ kpoo ọkụ, n'ihi na enwere ọtụtụ ígwè na pin piston, mmụba ya karịrị nke ahụ n'akụkụ ndị ọzọ. Na mgbakwunye, piston ahụ ga-enwetakwa mgbanwe nrụgide n'okpuru ọrụ nke nrụgide n'akụkụ. Nsonaazụ jikọtara nke mgbanwe ndị a dị n'elu na-eme ka akụkụ obe nke uwe mwụda piston ghọọ ellipse nwere axis ogologo kwụ ọtọ na ntụziaka nke pin piston. Na mgbakwunye, n'ihi nkesa na-adịghị mma nke okpomọkụ na oke n'akụkụ axis nke piston ahụ, mgbasawanye okpomọkụ nke akụkụ obe ọ bụla buru ibu n'elu ma pere mpe na ala.
