Ntchito ya gasket yophimba valavu ya galimoto - Ndi chiyani?
Mu dongosolo lovuta komanso lolondola la injini ya galimoto, pali zinthu zambiri zosaoneka ngati zazing'ono koma zofunika kwambiri. Gasket yophimba valavu ndi imodzi mwa izo. Ili ngati choteteza chete, chomwe chimagwira ntchito yake pamwamba pa injini ndikuwonetsetsa kuti injini ikugwira ntchito bwino.
Gasket yophimba ma valve ili pakati pa chivundikiro cha valavu ndi mutu wa silinda, ndipo ndi gawo lofunika kwambiri pa makina otsekera injini. Ntchito yake yayikulu ndikutseka, kuteteza kutuluka kwa mafuta a injini kuchokera pamalo olumikizirana pakati pa chivundikiro cha valavu ndi mutu wa silinda. Injini ikagwira ntchito, mafuta amkati mwa injini ayenera kuzungulira pakati pa zigawo zosiyanasiyana, zomwe zimathandiza kudzola, kuziziritsa, ndi kuyeretsa. Ngati gasket yophimba ma valve yalephera kutseka bwino, mafuta a injini adzatuluka, osati kungoyambitsa madontho a mafuta pa chipinda cha injini ndikukhudza mawonekedwe a injini, komanso zomwe zimapangitsa kuti mafuta a injini achepe, zomwe zimakhudza mphamvu ya mafuta a injini, motero zimafulumizitsa kuwonongeka kwa zigawo ndikufupikitsa moyo wa ntchito ya injini.
Kuwonjezera pa kupewa kutayikira kwa mafuta, gasket yophimba valavu imathanso kuletsa fumbi, chinyezi ndi zinyalala zina kulowa mkati mwa injini. Zigawo zolondola mkati mwa injini zimakhala ndi zofunikira kwambiri pa malo ogwirira ntchito. Fumbi ndi zinyalala zikalowa, zimatha kuyambitsa kuwonongeka pamwamba pa zigawozo, zomwe zimakhudza momwe zimagwirira ntchito nthawi zonse komanso ngakhale kupangitsa kuti zisagwire bwino ntchito. Gasket yophimba valavu imagwira ntchito ngati chotchinga cholimba, kuteteza zinthu zovulaza izi kulowa ndikuteteza ukhondo wa mkati mwa injini.
Pakadali pano, gasket yophimba valavu imathandizanso kusunga malo abwino opanikizika mkati mwa crankcase. Kukhazikika kwa kuthamanga mkati mwa crankcase ndikofunikira kwambiri kuti injini igwire bwino ntchito. Ntchito yotseka ya gasket yophimba valavu imathandiza kusunga kuthamanga uku, ndikutsimikizira kuti injini ikugwira ntchito bwino.
Komabe, popeza galimotoyo imagwiritsidwa ntchito kwa nthawi yayitali komanso chifukwa cha zinthu zosiyanasiyana zakunja, gasket yophimba valve imathanso kugwira ntchito bwino. Kulephera kofala kwambiri ndi kutayikira kwa mafuta. Pali zifukwa zambiri zomwe mafuta amatayikira gasket yophimba valve. Choyamba, gasket yophimba valve yokha imakalamba. Gasket yophimba valve imapangidwa kwambiri ndi rabara, ndipo imagwira ntchito pamalo otentha kwambiri, opanikizika kwambiri komanso onyowa mafuta kwa nthawi yayitali. Rabala pang'onopang'ono imataya kulimba kwake ndipo imauma ndi kusweka, zomwe zimapangitsa kuti ntchito yotseka ikhale yotsika komanso mafuta atuluke.
Kutsekeka kwa valavu yopumira mpweya yoyendetsedwa ndi crankcase (valvu ya PCV) ndi chimodzi mwa zifukwa zazikulu zomwe mafuta amatuluka kuchokera ku gasket yophimba valve. Vavu ya PCV ikatsekeka, kuthamanga mkati mwa crankcase kumawonjezeka. Pansi pa kuthamanga, mafuta a injini amatha kutuluka kudzera m'mipata ya gasket yophimba valve. Kuphatikiza apo, zinthu monga kusintha kwa chivundikiro cha valve, kuthamanga kwa screw kosagwirizana, komanso kusagwira bwino ntchito kwa sealing ring ya sealing ring zingayambitsenso kutuluka kwa mafuta kuchokera ku gasket yophimba valve.
Pamene gasket ya valavu yalephera, imayambitsa mavuto angapo pa injini. Choyamba, kutayikira kwa mafuta kumabweretsa kuchepa kwa mafuta a injini, zomwe zimakhudza mphamvu ya mafuta a injini ndikufulumizitsa kuwonongeka kwa zigawo. Kachiwiri, mafuta a injini omwe atuluka adzasungunuka kutentha kwa injini, zomwe zimapangitsa fungo loipa. Fungoli lingalowe mgalimoto kudzera mu makina oziziritsira mpweya ndikukhudza ubwino wa mpweya mkati mwa galimoto, motero zimakhudza thanzi la okwera ndi oyendetsa. Chofunika kwambiri, ngati mafuta a injini atuluka pa zigawo zotentha kwambiri monga chitoliro chotulutsa utsi, nthawi yachilimwe yotentha kapena galimoto ikayenda mofulumira kwambiri, ikhoza kuyambitsa moto, zomwe zingabweretse zoopsa zazikulu pachitetezo cha galimoto ndi okwera.
Zikapezeka kuti gasket yophimba valve ndi yolakwika, iyenera kuthetsedwa mwachangu. Pa magasket ophimba valve akale kapena owonongeka, amafunika kusinthidwa nthawi yomweyo. Mukasintha, sankhani zida zodalirika za fakitale zapamwamba kuti muwonetsetse kuti gasket yatsopano yophimba valve ili ndi magwiridwe antchito abwino otsekera. Nthawi yomweyo, panthawi yoyika, tsatirani njira zoyenera, yeretsani malo olumikizirana pakati pa chivundikiro cha valve ndi mutu wa silinda, ndikugwiritsa ntchito wrench yapadera yolimbitsa ma bolts malinga ndi torque yokhazikika kuti mupewe mavuto otayikira mafuta chifukwa cha kuyika kosayenera.
Pomaliza, ngakhale kuti gasket yophimba valavu ndi gawo laling'ono, imagwira ntchito yofunika kwambiri pakugwira ntchito kwa injini. Mukamagwiritsa ntchito galimoto tsiku ndi tsiku, mwiniwake ayenera kuyang'anitsitsa galimotoyo nthawi zonse kuti azindikire zolakwika zilizonse mu gasket yophimba valavu ndikuzithetsa. Mwanjira imeneyi injini imatha kugwira ntchito bwino, nthawi yogwira ntchito ya galimotoyo italikitsidwe, ndipo chitetezo choyendetsa galimotoyo chikhale chotsimikizika.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
