Kodi chivundikiro cha valve yagalimoto ndi chiyani
Chophimba cha valve yamagalimoto ndi gawo lamakina, lomwe nthawi zambiri limapangidwa ndi zitsulo, monga aluminium alloy ndi iron cast. Ili pamwamba pa makina a valve pamwamba pa injini ndipo amagwiritsidwa ntchito kuphimba zigawo za valve ndi valve drive kuti zitsimikizire kuti kayendetsedwe kabwino ka valve. Ntchito yaikulu ya chivundikiro cha valve imaphatikizapo kusunga dongosolo la valve kukhala loyera komanso kuteteza zonyansa monga fumbi, dothi, zinyalala kuti zisalowe mu dongosolo la valve, potero zimateteza zigawo zoyendetsa valve ndi ma valve. Kuonjezera apo, chivundikiro cha valve chimatsimikizira kuti mafuta sakudumphira kapena kulowa muzitsulo za valve, kupewa kuwonongeka kwa chigawo ndi kutaya mafuta.
Kapangidwe ka chivundikiro cha valve kumaphatikizapo thupi la valavu, chivundikiro cha valve, pakati pa valve, kunyamula, bolt, nati, gasket, chogwirira, chotengera ndi choyendetsa galimoto. Thupi la valavu ndilo gawo lalikulu lothandizira, ndipo chivundikiro cha valve chili pamwamba pa thupi la valve kuti chisindikize ndikugwira kulongedza kapena spool. Spool ndi gawo lolamulira lomwe limayendetsa kayendetsedwe ka kayendetsedwe kake, kuthamanga ndi kutuluka kwa madzi. Kulongedza kumakhala pakati pa spool ndi boneti kuti atseke ndikuchepetsa kutayikira. Maboti ndi mtedza amagwiritsidwa ntchito kulumikiza thupi la valve ku bonati kuti agwirizane. Gasket imakhala pakati pa bawuti ndi nati ndikuteteza thupi ndi kapu kuti zisavale. Chogwiriziracho chimagwiritsidwa ntchito poyendetsa valavu, chotengeracho chimathandizira spool ndikuchepetsa kukangana, ndipo chipangizo choyendetsa chimagwiritsidwa ntchito kuyendetsa kayendedwe ka spool kuti akwaniritse kuwongolera kwa valve.
Kusamalira chivundikiro cha valve ndikusinthanso ndikofunikira kwambiri. Kuyang'anitsitsa ndi kukonza nthawi zonse kungalepheretse mavuto omwe amayamba chifukwa cha zipewa za valve zotayirira kapena kusasindikiza bwino. Kuyika molakwika kungayambitse kulephera kwa valve, zomwe zingakhudze ntchito ya injini ndi moyo. Mukasintha boneti, zinthu zomwezo ndi kukula kwake monga gawo loyambirira ziyenera kugwiritsidwa ntchito kuwonetsetsa kuti injini ikuyenda bwino.
Ntchito yayikulu ya chivundikiro cha valve yamagalimoto imaphatikizapo zinthu izi:
Chisindikizo ndi chitetezo : Chophimba cha valve chimagwiritsidwa ntchito kuphimba dongosolo la valve kuteteza fumbi, dothi, zinyalala ndi zonyansa zina kuti zisalowe mu valavu, potero zimateteza zigawo za valve drive ndi ma valve, ndikuwonetsetsa kuti malo ogwira ntchito bwino a injini zamkati.
Kupaka mafuta ndi kupewa fumbi : Chophimba cha valve nthawi zambiri chimapanga chotsekedwa ndi mbali zonse za injini kuti zitsimikizire kudzoza ndi kuteteza mbali zamkati za injini. Kusindikiza kwake ndikofunikira kwambiri kuti injini igwire bwino ntchito, kuthira mafuta, chitetezo ndi chitetezo cha fumbi.
Sinthani mpweya wabwino wa crankcase : Nthawi zina, chivundikiro cha Valve chimakhalanso ndi Positive Crankcase Ventilation Valve (PCV), yomwe udindo wake ndi kuwongolera kuchuluka kwa utsi wamafuta opangidwa ndi makina opangira mpweya wa crankcase munjira yolowera, ndikudula mpweya wabwino injini ikatenthedwa kuteteza kulephera monga kuphulika kwa crankcase.
Zosankha zakuthupi : Zovala za mavavu nthawi zambiri zimapangidwa ndi zitsulo, zida zodziwika bwino zimaphatikizapo aloyi ya aluminiyamu ndi chitsulo choponyedwa. Zovala za mavavu a aluminiyamu ndizopepuka komanso zimakhala ndi kutentha kwabwino, pomwe zovundikira zitsulo zotayira zimakhala ndi mphamvu zambiri komanso kulimba.
Malingaliro okonza ndikusintha m'malo : Zovala za ma valve zimafunikira kuyang'aniridwa ndi kukonzedwa pafupipafupi, makamaka kuti muwone kulimba kwake ndikuyika. Ngati kapu ya valve ndi yotayirira kapena yosasindikizidwa bwino, imatha kupangitsa kuti ma valve alephereke, zomwe zimakhudza magwiridwe antchito ndi moyo wa injini. Mukasintha boneti, zinthu zomwezo ndi kukula kwake monga gawo loyambirira ziyenera kugwiritsidwa ntchito kuwonetsetsa kuti injini ikuyenda bwino.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina pa thndi site!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
