Menene piston ɗin mota
Piston na mota shine babban ɓangaren motsi a cikin injin ƙonewa na ciki wanda ke canza kuzarin zafi zuwa makamashin inji . Yana aika matsin lamba na ƙonewa zuwa crankshaft ta hanyar motsi mai juyawa kuma yana shiga cikin ƙirƙirar ɗakin ƙonewa.
Ma'anoni da ayyuka na Youdaoplaceholder0 Core
Piston na mota wani silinda ne da aka sanya a cikin silinda na injin. Babban aikinsa ya haɗa da:
Youdaoplaceholder0 Canza makamashi : Ana aika matsin lamba na iskar gas da konewar mai ke haifarwa zuwa crankshaft ta hanyar fil ɗin piston da sandar haɗawa, yana mai da shi ƙarfin juyawa.
Youdaoplaceholder0 Tsarin ɗakin ƙonewa : Tare da kan silinda da bangon silinda, yana samar da sararin ƙonewa a rufe.
Youdaoplaceholder0 Daidaitowar motsi : Zagayen bugun jini huɗu na ɗaukar iska, matsi, samar da wutar lantarki da kuma fitar da hayaki ana kammala su ta hanyar daidaita motsin da ke juyawa.
Youdaoplaceholder0 Siffofi da kayan gini
Piston ɗin ya ɗauki tsarin rabawa:
Youdaoplaceholder0 sama : Injunan mai suna ɗaukar matsin lamba kai tsaye, galibi suna ɗaukar tsarin saman lebur, yayin da injunan dizal galibi ana ƙera su da ramuka don biyan buƙatun ƙonewa.
Youdaoplaceholder0 head : Muhimmin sashi don shigar da zoben piston, wanda ke ɗauke da ramukan zobe 3 zuwa 4 (zoben gas da zoben mai) don cimma rufewa da shafawa.
Siket ɗin Youdaoplaceholder0 : Aikin jagora, rufin saman yana rage gogayya, ƙirar zamani tana da "gajere da kiba" don haɓaka tauri da zubar zafi.
Babban kayan shine ƙarfe na aluminum, wanda ya haɗa da sauƙi (rage ƙarfin inertial) da juriya mai zafi. Wasu samfuran da ke da babban aiki suna amfani da farantin nickel ko murfin yumbu
Youdaoplaceholder0 Yanayin aiki da ƙalubalen fasaha
Pistons suna aiki a ƙarƙashin yanayi mai tsauri:
Youdaoplaceholder0 Babban zafin jiki da matsin lamba mai yawa : Zafin ɗakin ƙonawa nan take ya wuce 2500K, kuma saman yana ci gaba da ɗaukar matsin lamba na 3-9MPa.
Motsin Youdaoplaceholder0 mai sauri : Injin mai zai iya kaiwa gudun juyawa na 6000rpm, wanda yayi daidai da gudun layi wanda ya wuce mita 20/s.
Youdaoplaceholder0 Ƙarfin rikitarwa : yana fuskantar nauyin tasirin lokaci-lokaci, matsin lamba a gefe da kuma nakasar matsin lamba ta zafi.
Pistons na zamani suna inganta tsarinsu ta hanyar nazarin abubuwa masu iyaka kuma suna ɗaukar sabbin fasahohi kamar hanyoyin sanyaya mai da kuma rufin rufin zafi don magance waɗannan ƙalubalen.
Ana iya raba dukkan piston zuwa sassa uku: saman piston, kan piston da kuma siket ɗin piston.
Babban aikin piston shine ɗaukar matsin lamba na konewa a cikin silinda da kuma canja wurin wannan ƙarfin zuwa crankshaft ta hanyar fil ɗin piston da sandar haɗawa. Bugu da ƙari, piston, tare da kan silinda da bangon silinda, suna samar da ɗakin konewa.
Saman piston wani ɓangare ne na ɗakin ƙonawa kuma galibi ana yin sa ne a siffofi daban-daban. A cikin injunan fetur, saman piston galibi yana ɗaukar saman lebur ko saman concave don sanya tsarin ɗakin ƙonawa ya yi ƙanƙanta, yankin zubar da zafi ya ƙanƙanta, kuma tsarin kera shi mai sauƙi. Sau da yawa ana amfani da pistons na sama masu convex a cikin injunan fetur masu bugun biyu. Sau da yawa saman piston na injin dizal ana yin shi ne a cikin ramuka daban-daban.
Kan piston shine ɓangaren da ke sama da wurin zama na piston. Ana sanya zoben piston a kan kan piston don hana iskar gas mai zafi da matsin lamba mai yawa shiga cikin akwati da kuma hana man injin shiga ɗakin ƙonewa. Yawancin zafin da saman piston ke sha ana kuma canja shi zuwa silinda ta kan piston sannan a ɗauke shi ta hanyar sanyaya.
Ana ƙera kan piston ɗin da ramukan zobe da dama don shigar da zoben piston. Adadin zoben piston ya dogara da buƙatun rufewa kuma yana da alaƙa da saurin injin da matsin lamba na silinda. Yawan zoben da ke cikin injin mai saurin gudu ya yi ƙasa da na injin mai ƙarancin gudu, kuma adadin zoben da ke cikin injin mai ƙarancin gudu ya yi ƙasa da na injin dizal. Injin mai na yau da kullun yana amfani da zoben gas guda biyu da zoben mai guda ɗaya. Injin dizal yana da zoben gas guda uku da zoben mai guda ɗaya. Injin dizal mai ƙarancin gudu yana amfani da zoben gas guda 3 zuwa 4. Don rage asarar gogayya, ya kamata a rage tsayin ɓangaren annular gwargwadon iko. A ƙarƙashin yanayin tabbatar da rufewa, ya kamata a yi ƙoƙari don rage adadin zoben.
Duk sassan da ke ƙarƙashin ramin zoben piston ana kiransu da siket ɗin piston. Aikinsa shine jagorantar piston don yin motsi mai juyawa a cikin silinda da kuma ɗaukar matsin lamba na gefe. Lokacin da injin ke aiki, saboda tasirin matsin lamba na iskar gas a cikin silinda, piston ɗin zai lanƙwasa ya canza siffarsa. Bayan an dumama piston ɗin, saboda akwai ƙarfe da yawa a fil ɗin piston, faɗaɗarsa ta fi ta sauran sassan. Bugu da ƙari, piston ɗin zai kuma fuskanci nakasar matsi a ƙarƙashin aikin matsin lamba na gefe. Sakamakon haɗakar nakasar da ke sama yana sa sashin giciye na siket ɗin piston ya zama ellipse tare da dogon axis a tsaye zuwa ga alkiblar fil ɗin piston. Bugu da ƙari, saboda rashin daidaituwar rarraba zafin jiki da nauyi a kan axis na piston, faɗaɗa zafin kowane sashe ya fi girma a sama kuma ƙarami a ƙasa.
"Idan kana son ƙarin bayani, ci gaba da karanta sauran labaran da ke wannan shafin!
Don Allah a kira mu idan kuna buƙatar irin waɗannan kayayyaki.
