Ihe mgbanaka piston bụ mgbanaka igwe eji etinye ya na piston groove. Enwere ụdị mgbanaka piston abụọ: mgbanaka mkpakọ na mgbanaka mmanụ. Enwere ike iji mgbanaka mkpakọ mechie ngwakọta gas na-ere ọkụ n'ime ụlọ ọkụ; a na-eji mgbanaka mmanụ na-ekpochapụ oke mmanụ na cylinder.
Mgbanaka piston bụ mgbanaka mgbanaka ọla nwere nnukwu mgbasawanye na nrụrụ apụta, yana etinyere ya n'ime akụkụ obe na oghere annular kwekọrọ na ya. Mgbanaka piston na-atụgharị ma na-atụgharị na-adabere na ọdịiche nrụgide nke gas ma ọ bụ mmiri mmiri iji mepụta akara n'etiti elu okirikiri nke mpụta nke mgbanaka na cylinder na otu akụkụ nke mgbanaka na mgbanaka mgbanaka.

Ndị agha na-arụ ọrụ na mgbanaka piston na-agụnye nrụgide gas, ike na-agbanwe nke mgbanaka ahụ n'onwe ya, ike na-eme ka mgbanaka na-emegharị ihe, ike esemokwu n'etiti mgbanaka na cylinder na mgbanaka mgbanaka. N'ihi ike ndị a, mgbanaka ga-emepụta mmegharị ndị bụ isi dị ka mmegharị axial, radial movement, na ntụgharị ntụgharị. Na mgbakwunye, n'ihi njirimara mmegharị ya, yana mmegharị ahụ na-adịghị mma, mgbanaka piston na-apụtaghị na ọ na-ese n'elu mmiri na ịma jijiji axial, radial irregular ije na ịma jijiji, ntụgharị ntụgharị nke mmegharị axial na-adịghị agbanwe agbanwe kpatara. Mmegharị ndị a na-adịghị mma na-egbochikarị mgbanaka piston ịrụ ọrụ. Mgbe ị na-emepụta mgbanaka piston, ọ dị mkpa ịnye egwuregwu zuru oke maka mmegharị ahụ dị mma ma na-achịkwa akụkụ na-adịghị mma.
Thermal conductivity
A na-ebufe nnukwu okpomọkụ nke ọkụ ọkụ na-emepụta na mgbidi cylinder site na mgbanaka piston, ya mere ọ nwere ike ime ka piston dị jụụ. Okpomọkụ a na-agbanye na mgbidi cylinder site na mgbanaka piston nwere ike iru 30-40% nke okpomọkụ nke elu piston na-etinye.
Ikuku tightness
Ọrụ mbụ nke mgbanaka piston bụ idobe akara n'etiti piston na mgbidi cylinder yana ịchịkwa ntapu ikuku na opekempe. Ọrụ a na-ebutekarị site na mgbanaka gas, ya bụ, nkwụsị nke ikuku abịakọrọ na gas nke injin ahụ kwesịrị ịchịkwa na opekempe n'okpuru ọnọdụ ọ bụla na-arụ ọrụ iji melite arụmọrụ ọkụ; gbochie cylinder na piston ma ọ bụ cylinder na mgbanaka ahụ ka ọ ghara ịkpata n'ihi nkwụsị ikuku; iji gbochie arụghị ọrụ nke ọma n'ihi mmebi mmanụ na-ete mmanụ.
Njikwa mmanụ
Ọrụ nke abụọ nke mgbanaka piston bụ ikpochapụ nke ọma mmanu mmanu nke etinyere na mgbidi cylinder ma nọgide na-eri mmanụ nkịtị. Mgbe ọkọnọ nke mmanụ lubricating dị ukwuu, a ga-amịnye ya n'ime ụlọ ọkụ, nke ga-eme ka mmanụ ọkụ dịkwuo elu. Ọzọkwa, n'ihi nkwụnye ego carbon nke combustion na-emepụta, arụmọrụ engine ga-enwe mmetụta dị oke njọ.
Na-akwado
N'ihi na piston dị ntakịrị ntakịrị karịa n'ime ime cylinder, ọ bụrụ na enweghị mgbanaka piston, piston adịghị eguzosi ike na cylinder na enweghị ike ịmegharị n'efu. N'otu oge ahụ, mgbanaka kwesịrị igbochi piston ka ọ ghara ịkpọtụrụ cylinder ahụ ozugbo, ma rụọ ọrụ nkwado. Ya mere, mgbanaka piston na-agbago na ala na cylinder, na mgbanaka ahụ na-ebuli elu ya nke ọma.
