Muhimmancin aikin ginin piston
A cikin tsarin aiki na injin mota, "alwatika na ƙarfe" wanda ya ƙunshi pistons, zoben piston, da fil ɗin piston shine babban cibiyar watsa wutar lantarki.
Ana iya ɗaukar piston a matsayin "mai canza wutar lantarki" na injin. Yana jure matsin lamba mai yawa daga iskar gas mai ƙonewa a cikin silinda kuma yana aika ƙarfin ta hanyar fil ɗin piston zuwa sandar haɗawa, a ƙarshe yana tura crankshaft don juyawa da canza kuzarin sinadarai na mai zuwa makamashin injiniya don motsi na abin hawa. A lokaci guda, saman piston da kan silinda, bangon silinda tare suna samar da ɗakin ƙonawa, suna samar da sarari don ƙona mai mai inganci kuma suna ba piston damar kammala bugun taimako guda uku na sha, matsi, da shaye-shaye a ƙarƙashin tuƙin sandar haɗawa, yana tabbatar da aikin injin mai zagaye.
Zoben piston shine "mai gadi mai aiki da yawa" na injin, wanda aka raba zuwa zoben iska da zoben mai. Zoben iska yana da alhakin rufe ɗakin ƙonawa da akwatin murhu, yana hana zubar iskar gas mai zafi da matsin lamba mai yawa, da kuma canja wurin kashi 70%-80% na zafi daga saman piston zuwa bangon silinda, wanda tsarin sanyaya ke wargazawa don guje wa lalacewar piston saboda yawan zafi. Zoben mai kamar "mai sarrafa man shafawa" ne, yana goge man da ya wuce kima a bangon silinda don hana shi shiga ɗakin ƙonewa da haifar da "ƙona mai", kuma a lokaci guda yana ƙirƙirar fim ɗin mai daidaitacce akan bangon silinda don rage gogayya da lalacewa tsakanin piston da bangon silinda. Bugu da ƙari, zoben piston na iya ba da tallafi ga piston don guje wa karo kai tsaye da bangon silinda da rage hayaniya da girgiza.
Filogin piston shine "gadar wutar lantarki" da ke haɗa piston da sandar haɗawa, wanda ke aika matsin iskar gas da piston ke ɗauka zuwa sandar haɗawa cikin sauƙi don cimma canji daga motsin piston zuwa juyawar sandar haɗawa. Don tabbatar da rarraba ƙarfi iri ɗaya, yawancinsu suna ɗaukar shigarwa mai iyo, wanda ke ba da damar filogin piston ya juya a hankali a cikin kujerar filogin piston da ƙaramin bushing na sandar haɗawa, wanda ke sa lalacewa ta fi daidaituwa; wasu samfura suna ɗaukar shigarwar rabin-shawagi, suna gyara filogin piston da ƙaramin kan sandar haɗawa da ƙusoshi, wanda ke haifar da tsari mai ƙanƙanta.
Kurakurai da alamu na yau da kullun
Haɗakar piston ɗin tana aiki a ƙarƙashin yanayin zafi mai yawa, matsin lamba mai yawa, da kuma yanayin gogayya mai yawa na dogon lokaci, kuma tana iya fuskantar matsaloli daban-daban, wanda ke shafar aikin injin kai tsaye.
Zoben piston wani bangare ne mai yawan lalacewa, kuma lalacewa ita ce matsalar da ta fi yawa. Gogayya ta dogon lokaci da zafin jiki mai yawa za su sa gibin da ke tsakanin zoben piston da bangon silinda ya karu, wanda hakan zai rage aikin rufewa, wanda zai haifar da rashin isasshen wutar lantarki a injin, yawan amfani da mai, har ma da abin da ke faruwa na "ƙona mai" inda bututun shaye-shaye ke fitar da hayaki mai launin shuɗi. Idan zoben piston ya makale saboda tarin carbon ko kuma ya rasa sassaucinsa, zai kuma haifar da canjin matsin lamba a silinda, wanda ke haifar da girgizar ƙasa, ƙaruwar matsin lamba a cikin akwati, da sauran matsaloli. Zoben piston da ya karye ya fi tsanani, inda zoben da ya karye yana iya goge bangon silinda, yana haifar da kama silinda kuma yana hana injin aiki.
Rashin nasarar fil ɗin piston galibi yana bayyana ne a matsayin hayaniya da lalacewa mara kyau. Lokacin da fil ɗin piston da ƙaramin kan sandar haɗin ko ramin wurin zama na piston suka lalace sosai kuma akwai gibi, injin zai fitar da sauti mai haske da ƙarfi a lokacin aiki, kuma sautin yana ƙaruwa lokacin da ake hanzartawa. Idan man shafawa bai yi kyau ba, fil ɗin piston ɗin zai iya lalacewa, wanda ke haifar da mummunan hulɗa tsakanin saman haɗuwa da ƙarin hayaniya mara kyau; da gaske, fil ɗin piston na iya gajiya da karyewa, yana haifar da lalacewar piston, har ma da toshe bututun silinda.
Kurakuran piston ɗin da kansa sun haɗa da ƙonewa a saman, lalacewar siket, da kuma kama silinda. Saman piston ɗin, ƙarƙashin tasirin iskar gas mai zafi da matsin lamba na dogon lokaci, yana iya kamuwa da ramuka ko tsagewa, wanda ke shafar aikin rufe ɗakin ƙonawa, wanda ke haifar da raguwar ƙarfin injin. Rufe siket ɗin zai ƙara gibin da ke tsakanin piston da bangon silinda, yana lalata kwanciyar hankalin fim ɗin mai, da kuma ƙara lalacewa da zubewar iskar gas. Rufe silinda shine babban yanayin gazawar layin piston da silinda, wanda galibi yakan faru ne sakamakon rashin daidaituwar silinda, gazawar tsarin sanyaya, ko rashin isasshen mai mai, wanda ke haifar da goge silinda, gazawar zubar da zafi na injin, har ma da kai tsaye.
Gano Kuskure da dabarun mayar da martani
Idan ana fuskantar matsaloli a cikin haɗa piston, ganowa da sarrafa shi cikin lokaci shine mabuɗin tabbatar da tsawon rayuwar injin.
Idan aka samu matsala a zoben piston, ana iya amfani da na'urar duba ciki ta amfani da na'urar endoscope don lura da ma'adanin carbon a saman piston da kuma ramin zoben, ko kuma a yi gwajin matsin lamba na silinda. Idan matsin lamba na silinda ya zama na al'ada amma yawan man da ake sha ya wuce kima, akwai yiwuwar rufewar zoben piston ya gaza. Ga ƙananan ma'adanan carbon da ke haifar da ɗan mannewa, ana iya ƙoƙarin ƙara wakilin sakin zoben piston. Don tsananin lalacewa ko karyewa, ana buƙatar a maye gurbin zoben piston. A lokuta masu mahimmanci, ya kamata a duba yanayin lalacewa na layin piston da silinda a lokaci guda.
Ana iya gano hayaniyar da ba ta dace ba daga fil ɗin piston ta hanyar gwajin kashe wuta: idan hayaniyar ta ragu ko ta ɓace bayan an yanke wutar, yawanci tana faruwa ne sakamakon karyewar fil ɗin piston; idan hayaniyar ta ƙara rikicewa, tana iya faruwa ne saboda yawan sharewa. Lokacin da ake magance ta, ana buƙatar a maye gurbin fil ɗin piston da ya lalace, kuma ya kamata a duba yanayin lalacewa na bearing ɗin sandar haɗin gwiwa da ramin wurin zama na piston. Idan ya cancanta, a yi gyara ko maye gurbinsa.
Gane lahani na piston yana buƙatar cikakken hukunci bisa ga alamun. Misali, hayakin shudi da ke fitowa daga bututun hayaki na iya nuna lalacewar zoben piston ko kuma jan layin silinda na piston. Idan ƙarfin injin ya ragu tare da matsin lamba na ɗakin konewa mara kyau, ya zama dole a duba lalacewar ƙonewa a saman piston. Idan piston ya yi rauni sosai, ya sa shi a siket, ko kuma ya fito daga silinda, yawanci yana da mahimmanci a maye gurbin piston, kuma ya kamata a binciki dalilan da ke haifar da lalacewar tsarin sanyaya da man shafawa don guje wa sake dawowa.
A lokacin gyaran yau da kullum, maye gurbin man injin mai inganci akai-akai, kiyaye tsaftar matatar iska, da kuma guje wa aiki mai nauyi na dogon lokaci na iya rage lalacewar sassan piston yadda ya kamata da kuma tsawaita rayuwar injin.
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.
