Igikoresho cyo kugenzura imodoka gisobanura iki?
Akamaro k'ubuyobozi bw'ingufu ni ukuyobora ingendo z'ingufu, kugenzura ko ingufu zikora ingendo zihuza, gutuma ingufu n'impeta z'intebe z'ingufu bihura neza, no kohereza ubushyuhe bw'ingufu z'ingufu ku mutwe wa silinda.
Ubushyuhe bw'imikorere y'umurongo wa valve nabwo buri hejuru cyane, hafi 200°C. Iyo igice cy'umugozi kigiye mu muyoboro w'umurongo, gishyirwamo amavuta ya moteri gusa ava mu gice cy'umurongo wa valve, bityo kikaba gishobora kwangirika. Kubwibyo, ibikoresho by'icyuma cya ductile cyangwa ifu bifite ubushobozi bwo kwiyambura bikunze gukoreshwa mu gukora ibice bimwe na bimwe, bigashyirwa mu mwobo w'intebe w'umurongo wa valve ku mutwe wa silindiri bifite uburyo runaka bwo kubibuza kugwa. Moteri zimwe zikoresha impeta zo gufata kugira ngo zikosore kandi zishyireho umurongo wa valve kugira ngo zidacika.
Igice cyo hasi cy'ubuyobozi bw'ingufu kigera mu miyoboro y'amazi yinjira n'ayoherezwa mu kirere. Kugira ngo hirindwe ko umwuka udashobora kugera, uruziga rw'inyuma rw'ingufu rukorwa nk'urusate. Hari icyuho cya mm 0.05 kugeza kuri 0.12 hagati y'ubuyobozi bw'ingufu n'inkingi y'ingufu, bigatuma umutwe w'ingufu ugenda neza mu murongo w'ubuyobozi.
Aka gakoresho k’ingufu gashyigikira kandi kayobora ingufu zigenda zigaruka imbere muri zo, kakagenzura ko ingufu n’intebe z’ingufu bishobora kwinjira neza, kandi kakanafasha mu gutanga ubushyuhe.
Hari ubwoko bubiri bw'abayobora valve: ubwoko bw'integral n'ubwoko bw'integral. Ubuyobozi bw'abayobora valve butunganya mu buryo butaziguye umwobo w'umugongo wa valve mu mutwe wa silinda. Ubuyobozi bw'abayobora valve bushyirwa mu muyoboro w'uruziga unyuze mu mwobo w'abayobora mu mutwe wa silinda ufite interference iri hagati ya mm 0.015 na 0.065.
Amwe mu mabwiriza y’ingufu afite imiyoboro y’impeta ikozwe ku buso bw’inyuma bw’umuzenguruko, ishyirwamo impeta zifata kugira ngo zishyirwe mu mwanya wazo, ikagabanya ubujyakuzimu bw’inkombe yo hasi mu nzira y’ubuhumekero kandi ikabuza ko irekura.
Muri rusange, hagati y’umugongo wa valve n’umurongo wa valve haba hari umwanya uri hagati ya mm 0.05 na 0.12. Bisigwa amavuta ya moteri ava mu bice by’imashini itwara umuriro.
Iyo icyuho kiri hagati y’umugozi w’imvange n’umurongo w’imvange ari gito cyane, biroroshye gutuma umugozi w’imvange ufatana kandi ukagira umugozi mubi, ibyo bikaba byatera gucika intege kw’imvange no kugabanuka k’imikorere y’ingufu, igiciro gito n’ibyuka bihumanya.
Iyo icyuho kiri hagati y'umugongo w'imvange n'umurongo w'imvange ari kinini cyane, bizatera ibintu bidasanzwe bikurikira:
Intebe y'imvange ntabwo ihamye, imikorere yo gufunga iragabanuka, kandi irashaza ku muvuduko wihuta, bigatuma imvange ishaje kandi imikorere y'ingufu, igabanuka ry'ingufu n'ibyuka bihumanya.
Ugusohoka k'umwuka mu buryo bwo kwinjiza umwuka bituma uruvange ruri muri moteri ya lisansi rugabanuka.
Amavuta menshi ya moteri anyura mu myobo yinjira mu cyumba cyo gutwika cyangwa mu nzira y'umwuka (cyane cyane mu gihe cyo kwinjiramo), bigatuma moteri ikoresha amavuta menshi, imyuka y'umwotsi w'ubururu, kandi ikarushaho kwihuta mu kubika karubone.
Mu gihe cyo gusohora umwuka, umwuka usohoka winjira muri crankcase unyuze mu cyuho kiri hagati y'umugozi w'imashini isohora umwuka n'umurongo w'imashini iyobora.
Iyo umuvuduko uri ku cyambu cy’imyotsi uri hasi ugereranije n’uri mu gikapu cy’imyotsi, amavuta ya moteri yinjira mu cyambu cy’imyotsi binyuze mu cyuho kiri hagati y’agace k’imyotsi n’agasanduku k’imyotsi.
Impamvu y’umwotsi w’ubururu mu gihe cyo gutangira imodoka ni uko icyuho cy’umurongo w’imashini isohora umwuka kiba kinini cyane. Iyo imashini ihagaze, amavuta yinjira mu cyuho cy’umurongo w’imashini isohora umwuka mu cyumba cyo gutwika maze agafata ku gice cy’imashini isohora umwuka, hanyuma agashya mu gihe cyo gutangira imodoka. Iki kintu kizagabanuka cyangwa kikabura uko ubushyuhe bwa moteri bwiyongera.
Akamaro k'ikimenyetso cy'amavuta ya valve ni ukurinda amavuta menshi ya moteri kwinjira mu cyumba cyo gutwika cyangwa mu miyoboro y'amazi asohoka n'ayoherezwa mu kirere binyuze mu cyuho kiri hagati y'ikimenyetso cy'amashanyarazi n'inkingi y'amashanyarazi. Ni impeta yo gufunga ya rubber, ishyirwa ku mpera yo hejuru y'ikimenyetso cy'amashanyarazi. Iyo ikimenyetso cy'amavuta ya valve cyangiritse, amavuta menshi ya moteri azamanuka anyuze mu cyuho kiri hagati y'ikimenyetso cy'amashanyarazi n'ikimenyetso cy'amashanyarazi asohoka mu cyumba cyo gutwika cyangwa mu nzira z'umwuka, bigatuma amavuta ya moteri yiyongera. Ibi biherekezwa n'umwotsi w'ubururu mu byuka kandi byihutisha ikorwa rya karubone ku mashini no mu cyumba cyo gutwika.
Uburyo bwo gusimbuza abayobora valve bugabanyijemo ubwoko bubiri: gusimbuza abayobora valve flanges no gusimbuza abayobora valves badafite flanges.
Hari ubuyobozi bwa valve ya flange
Iyo umutwe wose wa silindiri ushyushye kugeza kuri dogere 100-150 mu gasanduku gafite ubushyuhe buhoraho, kuraho hanyuma uzamure umutwe wa silindiri. Koresha igikoresho cyo gukuraho umurongo wa valve n'igikoresho cyo guteranya kugira ngo usunike umurongo wa valve ugana ku ruhande rwa camshaft. Hanyuma shyira amavuta yo kwisiga kuri O-ring nshya, uyishyire kuri umurongo mushya wa valve, hanyuma ukoreshe igikoresho cyo gukuraho umurongo wa valve n'igikoresho cyo guteranya kugira ngo ushyire umurongo mushya wa valve ku ruhande rwa camshaft. Umutwe wa silindiri umaze gukonja, suka amavuta make mu mwobo w'imbere wa valve, hanyuma ukoreshe icyuma gifata umurongo wa valve kugira ngo ugabanye umurongo wa valve kugira ngo ubone umwanya ukwiye hagati y'umugongo wa valve n'umurongo wa valve. Amaherezo, sukura neza umutwe wa silindiri ukoresheje lisansi cyangwa peteroli hanyuma ushobora gushyirwaho kandi ugakoreshwa. Simbuza umurongo wa valve nta flanges
Mbere yo gukuraho umurongo wa valve kuri cylinder, pima uburebure bw'igice cyagaragaye ukoresheje caliper ya vernier hanyuma ufate inyandiko. Iyo umutwe wa cylinder ushyushye kugeza kuri dogere 100-150 mu gasanduku k'ubushyuhe buhoraho, ukuremo hanyuma uzamure umutwe wa cylinder. Koresha igikoresho cyo gukuraho umurongo wa valve n'igikoresho cyo guteranya kugira ngo usunike umurongo wa valve ugana ku ruhande rwa camshaft. Hanyuma, koresha igikoresho cyo gukuraho umurongo wa valve n'igikoresho cyo guteranya kugira ngo unyure umurongo mushya wa valve mu ruhande rwa camshaft. Mu gihe upima uburebure bw'igice cyagaragaye cy'umurongo wa valve, shyira umurongo mushya wa valve buhoro buhoro kugeza wujuje ibisabwa. Nyuma y'uko umutwe wa cylinder ukonje, suka amavuta make mu mwobo w'imbere wa valve hanyuma ukoreshe agakoresho ka valve kugira ngo ugabanye umurongo wa valve kugira ngo ubone umwanya ukwiye hagati y'umugongo wa valve n'umurongo wa valve. Hanyuma, sukura neza umutwe wa cylinder ukoresheje lisansi cyangwa peteroli hanyuma ushobora gushyirwaho kandi ugakoreshwa.
