Muhimmancin zoben piston na mota
A cikin ainihin "zuciyar ƙarfi" ta injin mota, babu shakka zoben piston shine babban mai kiyayewa, yana gudanar da ayyuka da yawa masu mahimmanci waɗanda ke shafar aiki da tsawon rayuwar injin.
Da farko, yana da aikin rufewa, wanda ke manne da piston da bangon silinda sosai, kamar shinge mai ƙarfi, yana hana iskar gas mai zafi da matsin lamba mai yawa a cikin ɗakin ƙonawa shiga cikin akwati, yana tabbatar da daidaiton matsin lamba a cikin silinda da kuma samar da isasshen wutar lantarki ga injin. Da zarar rufewar ta gaza, ingancin ƙonewar injin zai ragu sosai, kuma wutar za ta yi rauni.
Na biyu, yana da aikin sarrafa mai. Yayin da piston ke motsawa sama da ƙasa a cikin silinda, yana kama da mai tsaftacewa mai kyau, yana goge man da ya wuce kima a bangon silinda don hana man shiga ɗakin ƙonewa don ƙonewa, ta haka yana sarrafa yawan amfani da mai da rage farashin aiki. A lokaci guda, yana iya samar da fim ɗin mai iri ɗaya a bangon silinda, yana samar da kyakkyawan man shafawa ga piston da bangon silinda, yana rage lalacewa.
Bugu da ƙari, zoben piston yana da ayyukan watsa zafi da tallafi. A cikin yanayin aiki mai zafi da matsin lamba mai yawa na injin, yana iya canja wurin babban adadin zafi da saman piston ke samarwa zuwa bangon silinda cikin sauri, sannan ya sake shi ta hanyar tsarin sanyaya, yana tabbatar da cewa injin yana aiki a yanayin zafi mai dacewa. A lokaci guda, yana iya taimakawa motsin piston da kuma samar da tallafi mai ƙarfi, yana hana piston taɓa bangon silinda kai tsaye da haifar da lalacewa.
Kurakurai da alamu na yau da kullun na zoben piston na mota
Duk da cewa zoben piston yana taka muhimmiyar rawa, ba makawa a gamu da kurakurai yayin aiki a cikin mawuyacin yanayi, galibi suna bayyana a matsayin lalacewa, karyewa, da mannewa, sannan kuma akwai alamun bayyanar cututtuka.
Idan aka sa zoben piston, aikin rufewa yana raguwa, kuma iskar gas a cikin ɗakin konewa yana ɓuɓɓuga, wanda ke haifar da ƙarancin ƙarfin injin, jinkirin hanzari, da wahalar hawa ko hawa. A lokaci guda, mai yana iya shiga ɗakin konewa don ƙonewa, yana haifar da ƙaruwar yawan amfani da mai, yana buƙatar ƙarin mai akai-akai, kuma hayakin shuɗi zai fito daga bututun hayaki, musamman lokacin da sanyi ya fara ko ya yi sauri sosai. Bugu da ƙari, ƙonewa mara cikakke zai haifar da ƙaruwar yawan amfani da man injin, wuce ƙa'idodin hayaki, har ma da girgiza injin da zafi fiye da kima.
Karyewar zoben piston babban matsala ce, wadda yawanci ke faruwa ne sakamakon matsalolin ingancin masana'antu, lalacewar silinda mai tsanani, toshewar ma'adanan carbon, rashin girman zoben da bai dace ba, ko kuma yawan aiki. Bayan karyewar, za a ga sautunan bugun ƙarfe a cikin injin lokacin da ake ƙara gudu ko kuma lokacin da yake fara sanyi, kuma sautin zai fi bayyana. A lokaci guda, ƙarfin injin zai ragu sosai, kuma matsin mai na iya zama ba daidai ba.
Manne zoben piston galibi yana faruwa ne sakamakon mai datti, iskar shaka mai tsanani, manne zoben piston a cikin ramin zoben, ko kuma yawan sinadarin carbon da ke toshe ramin zoben. Mannewa zai sa zoben piston ya rasa laushi kuma ya kasa mannewa da bangon silinda, wanda ke haifar da irin wannan alamun gazawar rufewa, ƙaruwar amfani da mai, da raguwar wutar lantarki.
Ganewa da hanyoyin magance kurakuran zoben piston na mota
Idan abin hawa ya nuna alamun da ke sama, ya zama dole a gano zoben piston akan lokaci. Hanyoyin ganewar asali sun haɗa da duba endoscope, lura da ma'adinan carbon a saman piston da kuma laka mai a cikin ramin zobe ta hanyar ramin toshewa; gwajin matsin lamba na silinda, idan matsin lamba na silinda ya zama al'ada amma akwai yawan shan mai mai yawa, yawanci matsalar zoben piston ce; hanyar lura mai ƙarfi, toshe ramin dipstick na mai a yanayin sanyi, jin yanayin tserewar iskar gas da amfani da nama don gano iskar iska; duba hanyar kawarwa, fifita duba sassan da suka lalace cikin sauƙi kamar bawuloli masu fitar da hayaki da turbochargers, sannan tabbatar da matsalar zoben piston; gwajin wakilin gyara, ƙara wakilin sakin zoben piston da kuma sa ido kan canjin amfani da mai don tantance matakin mannewa.
Ga kurakurai daban-daban, mafita kuma sun bambanta. Ga ƙananan lalacewa ko mannewa, ana iya amfani da wani wakili na musamman na gyaran zoben piston don dawo da sassauci da aikin rufe zoben piston ba tare da wargaza injin ba. Misali, "Siyou Pu 2 + 18 fasahar gyara mara lalacewa" na iya aiki akan yanayin makale na zoben gas da zoben mai a lokaci guda, yana yin gyare-gyare masu ƙarfi a ƙarƙashin yanayin tuƙi don guje wa haɗarin lalacewa ta biyu. Idan zoben piston sun lalace sosai ko sun karye, yana buƙatar a maye gurbinsu nan da nan. Lokacin maye gurbinsu, ya zama dole a zaɓi samfura masu inganci kuma a je shagon 4S ko shagon gyara na ƙwararru, inda ma'aikata ƙwararru za su gudanar da aikin. Saboda maye gurbin zoben piston yana buƙatar wargaza injin, tsarin yana da rikitarwa. Idan ba a yi shigarwa yadda ya kamata ba, yana iya shafar aikin injin har ma ya haifar da mummunan lalacewa. Bugu da ƙari, yayin tuƙi na yau da kullun, canza matattarar man injin akai-akai, amfani da mai mai inganci, da kuma guje wa injin daga aiki a ƙarƙashin nauyi na dogon lokaci na iya tsawaita rayuwar zoben piston yadda ya kamata da rage faruwar lahani.
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.
