Zvinorevei gwara revharuvhu yemotokari
Basa regwara remavharuvhu nderekutungamira kufamba kwemavharuvhu, kuona kuti mavharuvhu anoita kufamba kwakarongeka, kugonesa mavharuvhu nemhete dzechigaro chevharuvhu kuti zvikwane nemazvo, uye kuendesa kupisa kwetsinde yevharuvhu kumusoro wesilinda.
Tembiricha yekushanda kweguide yevharuvhu yakakwirawo zvakanyanya, inenge 200℃. Kana tsinde yevharuvhu ichifamba muguide tube, inozorwa mafuta einjini anobuda muguide train, saka inowanzo pera. Nokudaro, zvinhu zvesimbi zvine ductile iron kana powder metallurgy zvine hunhu hwekuzvitsvedza zvinowanzo shandiswa kugadzira zvikamu zvakasiyana, izvo zvinodzvanywa mumaburi echigaro cheguide yevharuvhu pamusoro wecylinder zvine imwe nzira yekudzivirira kuti zvisadonha. Mamwe mainjini anoshandisa ma retaining rings kugadzirisa uye kuisa maguide evharuvhu kudzivirira kuti asasununguke.
Chikamu chepazasi chegwara remavharuvhu chinotambanukira mumigero yekupinda nekubuda kwemhepo. Kuti mweya usapinda, denderedzwa rekunze remucheto unotambanukira rinogadzirwa kuita chimiro chekona. Pane mukaha we 0.05 kusvika 0.12mm pakati pegwara remavharuvhu negwara remavharuvhu, zvichibvumira gwara remavharuvhu kufamba zvakasununguka mukati megwara.
Gwaro remavharuvhu rinotsigira uye rinotungamira mavharuvhu anofamba-famba mukati maro, richiona kuti mavharuvhu nezvigaro zvemavharuvhu zvinokwana zvakanaka, uye rinobatsirawo kuendesa kupisa.
Kune mhando mbiri dzemavharuvhu anotungamira: rudzi rwakabatana uye rudzi rwakasungirirwa. Gwaro revharuvhu rakabatana rinobata zvakananga buri remudzi wevharuvhu riri mumusoro wesirinda. Gwaro revharuvhu rakabatanidzwa rinodzvanywa muchubhu ine cylindrical nepaburi rekutungamira riri mumusoro wesirinda rine kupindirana kwe 0.015 kusvika 0.065mm.
Mamwe mavharuvhu ane migero yeringi yakagadzirwa pamusoro pekunze wakaita sedenderedzwa, iyo yakaiswa maringi ekuchengetedza kuti aiise panzvimbo yayo, ichideredza kudzika kwemucheto wepasi wenzira yekufema uye ichidzivirira kuti isasununguke.
Kazhinji pane nzvimbo yekuisa vharuvhu pakati pe 0.05 kusvika 0.12mm pakati pe valvu ne valvu guide. Inozorwa nemafuta einjini anodururwa kubva muzvikamu zve valvu.
Kana mukaha uri pakati pehunde yevharuvhu negwara revharuvhu uri mudiki zvakanyanya, zviri nyore kukonzera kuti hunde yevharuvhu iome uye isavharwe zvakanaka, izvo zvinogona kukonzera kupera kwevharuvhu uye kudzikira kwekushanda kwesimba, kushaya simba uye kuburitswa kwemhepo.
Kana mukaha uri pakati pehunde yevharuvhu negwara revharuvhu wakakura zvakanyanya, zvichakonzera zviitiko zvisina kujairika zvinotevera:
Chigaro chemavharuvhu hachina kugadzikana, mashandiro ekuvhara anodzikira, uye anosakara nekukurumidza, zvichikonzera kupera kwevharuvhu uye kudzikira kwekushanda kwesimba, kushaya simba, uye kuburitswa kwemhepo.
Kubuda kwemhepo mu intake system kunoita kuti musanganiswa uri muinjini yepeturu uve mutete.
Mafuta emuinjini akawandisa anonyura nepaburi remukamuri rinopisa kana panopinda mweya (kunyanya panguva yekudya), zvichikonzera kuwedzerwa kwemafuta emuinjini, kuburitswa kweutsi hwebhuruu, uye kuumbwa kwecarbon deposit nekukurumidza.
Munguva yekubuda kwemhepo, gasi rinobuda mumhepo rinopinda mu crankcase nepakati pegomba riri pakati pe stem yevharuvhu yekubuda negwara revharuvhu.
Kana kumanikidzwa kwepombi yekubuda kwemhepo kwakaderera pane kuri mukati me crankcase, oiri yeinjini inodonhera mupombi yekubuda kwemhepo kuburikidza nemukana uri pakati pe stem yevharuvhu yekubuda kwemhepo negwara revharuvhu.
Chikonzero cheutsi hwebhuruu panguva yekutanga injini chinowanzova chekuti mukaha wegwara revharuvhu remhepo wakakura zvakanyanya. Kana muchina wamira, mafuta anonyura nepamukaha wegwara revharuvhu remhepo opinda mukamuri rinopisa moto onamatira kune exhaust manifold, uye anotsva panguva yekutanga injini. Chiitiko ichi chinodzikira kana kunyangarika sezvo tembiricha yeinjini ichiwedzera.
Basa rechisimbiso chemafuta evharuvhu nderekudzivirira mafuta einjini akawandisa kuti asapinde mukamuri rinopisa kana mumigero yekupinda nekubuda nepakati pemugero uri pakati pegwara revharuvhu nesimbi yevharuvhu. Irin'i rerubha rinovhara, rakaiswa kumucheto wepamusoro wegwara revharuvhu. Kana chisimbiso chemafuta evharuvhu chakakuvara, mafuta einjini akawandisa achanyura pasi nepakati pemugero uri pakati pevharuvhu negwara revharuvhu achipinda mukamuri rinopisa kana mumhepo, zvichikonzera kushandiswa kwakawanda kwemafuta einjini. Izvi zvinoperekedzwa neutsi hwebhuruu mumhepo inopisa uye zvinokurumidzisa kuumbwa kwecarbon deposits pamavharuvhu nemukamuri rinopisa.
Nzira dzekutsiva mavharuvhu dzinokamurwa kuita mhando mbiri: kutsiva mavharuvhu neflanges uye kutsiva mavharuvhu asina flanges.
Pane gwara revharuvhu reflange
Kana musoro wese wecylinder wapiswa kusvika 100-150℃ mubhokisi rinodziya nguva dzose, bvisa wosimudza musoro wecylinder. Shandisa chishandiso chekuparadzanisa vharuvhu nechokubatanidza kusundira chitungamiri chevharuvhu kudivi recamshaft. Wobva waisa mafuta ekuzora paO-ring itsva, woisa paguide itsva yevharuvhu, wobva washandisa chishandiso chekuparadzanisa vharuvhu nechokubatanidza kusundira chitungamiri chitsva chevharuvhu kudivi recamshaft. Kana musoro wecylinder watonhora, donhedza mafuta ekucheka muburi remukati reguide yevharuvhu, uye shandisa chigadziriso chevharuvhu kuchekerera chitungamiri chevharuvhu kuti uwane nzvimbo yakakodzera pakati pesimbi yevharuvhu neguide yevharuvhu. Pakupedzisira, chenesa musoro wecylinder nepeturu kana parafini uye unogona kuisa uye kushandisa. Tsiva chitungamiri chevharuvhu pasina maflanges
Usati wabvisa gwara revharuvhu kubva musirindiri, yera kukwirira kwechikamu chakavhurika uchishandisa vernier caliper wonyora pasi. Kana musoro wesirindiri wapisa kusvika 100-150℃ mubhokisi rinopisa nguva dzose, ribudise wosimudza musoro wesirindiri. Shandisa turuso revharuvhu rekuparadzanisa nekugadzira kuti usundire gwara revharuvhu kudivi recamshaft. Wobva washandisa turuso revharuvhu rekuparadzanisa nekugadzira kuti uise gwara idzva revharuvhu kudivi recamshaft. Paunenge uchiyera kukwirira kwechikamu chakavhurika chegwara revharuvhu, fambisa gwara idzva revharuvhu zvishoma nezvishoma kusvika rasvika pazvinodiwa. Mushure mekunge musoro wesirindiri watonhorera, donhedza mafuta ekucheka mugomba remukati regwara revharuvhu uye shandisa hinge yegwara revharuvhu kuti ucheke gwara revharuvhu kuti uwane nzvimbo yakakodzera pakati pesimbi yevharuvhu negwara revharuvhu. Pakupedzisira, chenesa musoro wesirindiri nepeturu kana parafini uye unogona kuisa nekushandisa.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
