Kodi kasupe wa valavu ya galimoto ndi chiyani?
Kasupe wa valavu yamagalimoto ndi gawo lofunika kwambiri la injini yamagalimoto, lomwe lili pakati pa mutu wa silinda ndi mpando wa valavu wozungulira. Ntchito yake yayikulu ndikuwonetsetsa kuti valavuyo yakhazikika bwino komanso yolumikizidwa bwino kuti valavu isagunde panthawi ya kugwedezeka kwa injini, motero kuwononga kutseka kwake.
Masiponji a ma valve nthawi zambiri amapangidwa ndi waya wachitsulo chapamwamba kwambiri ndipo amatenthedwa kuti awonjezere mphamvu zawo zotopa. Pofuna kupewa dzimbiri la kasupe, pamwamba pake padzakhala galvanized kapena phosphating. Malekezero ake awiri ayenera kukhala osalala komanso olunjika ku mzere wa kasupe kuti apewe kugwedezeka panthawi yogwira ntchito.
Kapangidwe ndi kusankha zinthu za kasupe wa valavu zimakhudza kwambiri magwiridwe antchito a injini. Pofuna kupewa kugwedezeka, injini zamakono nthawi zambiri zimagwiritsa ntchito masikapu osinthasintha kapena masikapu awiri okhazikika mozungulira. Kapangidwe ka kasupe wawiri kamaphatikizapo masikapu awiri ozungulira mozungulira mkati ndi kunja. Kulimba kwa kasupe wakunja ndi kwakukulu, komwe kumatha kuletsa kugwedezeka, ndipo kasupe wina akasweka, winayo amatha kupitiriza kugwira ntchito kuti atsimikizire kutsekedwa kwabwinobwino kwa valavu .
Mfundo yogwira ntchito ya kasupe wa valavu ndikuwonetsetsa kuti valavuyo yayikidwa bwino pampando wa valavu pogonjetsa mphamvu ya inertial panthawi yotseka valavu ndikuletsa valavuyo kuti isadumphe pansi pa katundu wopanikizika. Kuphatikiza apo, kasupe wa valavu amathanso kuwongolera kuyenda kwa valavuyo kuti apewe kulekanitsidwa kwa makina a valavu .
Mwachidule, ngakhale kuti kasupe wa valavu ndi kakang'ono mu injini, ntchito yake ndi yofunika kwambiri kuti injini igwire bwino ntchito komanso kuti igwire bwino ntchito.
Udindo waukulu wa kasupe wa valve yamagalimoto umaphatikizapo zinthu izi:
Onetsetsani kuti mpando wa valavu wa nthawi yake ndi wogwirizana bwino: kasupe wa valavu akhoza kuonetsetsa kuti valavu ikhoza kuyikidwa bwino ndi mpando wa valavu kapena mphete ya mpando wa valavu ikatsekedwa, kuletsa valavu kuti isadumphe pamene injini ikugwedezeka, kuti isunge chisindikizo chabwino.
gonjetsani mphamvu ya inertial: valavu ikatsegulidwa, makina a valavu amapanga mphamvu ya inertial, kasupe wa valavu amatha kugonjetsa mphamvu izi za inertial kuti atsimikizire kuti magawo otumizira nthawi zonse amalamulidwa ndi CAM ndipo salekanitsidwa .
Kuletsa kugwedezeka ndi kugwedezeka: Pofuna kupewa kugwedezeka kwa masika a valavu panthawi yogwira ntchito, injini zina zimagwiritsa ntchito kapangidwe ka masika a mavalavu awiri, kuzungulira kwa masika awiri moyang'anizana, komwe kumatha kuchepetsa kugwedezeka kwa masika, ndikuwonjezera kukhazikika kwa masika a valavu.
Mphamvu yabwino komanso kudalirika kwa kutopa: Masiponji a ma valve nthawi zambiri amapangidwa ndi waya wachitsulo chapamwamba kwambiri ndipo amatenthedwa kuti awonjezere kukana kwawo kutopa. Kuti apewe dzimbiri, pamwamba pake pamakhala galvanized kapena phosphate.
Zosinthasintha kuti zikhale ndi mphamvu yosinthasintha komanso magwiridwe antchito othamanga kwambiri: ndi injini yomwe ikukula mwachangu komanso mothamanga kwambiri, ma valve springs amafunika kupirira mphamvu yosinthasintha komanso liwiro loyankha mwachangu. Chifukwa chake, kapangidwe ndi kupanga ma valve springs kumafuna zofunikira zaukadaulo zapamwamba.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
