Kodi gasket ya chitoliro chotulutsa utsi cha galimoto ndi chiyani?
Gasket ya exhaust manifold (yomwe imadziwikanso kuti exhaust manifold gasket kapena exhaust pipe interface gasket) ndi gawo lotsekera lomwe limayikidwa pakati pa exhaust manifold (yomwe imatchedwanso exhaust branch pipe) ndi doko la exhaust la silinda head. Imagwiritsidwa ntchito poletsa kutuluka kwa mpweya wotentha wotulutsa mpweya pamalo olumikizirana.
Ntchito zazikulu
Kutseka mpweya wotentha wotulutsa mpweya: Kumaletsa kutuluka kwa mpweya wotentha wotulutsa mpweya kuchokera pamalo olumikizirana pakati pa exhaust manifold ndi silinda head.
Chitetezo cha kutentha: Ma gasket ena amaphatikizidwa ndi zophimba kutentha, zomwe zimachepetsa kusamutsa kutentha kupita ku zigawo zina mu gawo la injini ndikuchepetsa kusiyana kwa kutentha kwa mutu wa silinda, motero zimakulitsa moyo wake wautumiki.
Kuchepetsa phokoso: Kumathandiza kuchepetsa phokoso lamphamvu lotchedwa "sizzling" kapena "pop" lomwe limayamba chifukwa cha kutuluka kwa mpweya mu utsi.
Kuonetsetsa kuti mpweya wotulutsa mpweya ukutsatiridwa: Kuonetsetsa kuti mpweya wotulutsa mpweya ukulowa mu chosinthira mphamvu cha njira zitatu kapena turbocharger m'njira yopangidwira, kukwaniritsa malamulo oteteza chilengedwe.
Mapangidwe ofanana
Kapangidwe ka chitsulo ndi graphite: Yopangidwa pomanga mbale yachitsulo yokhala ndi graphite, imapirira kutentha kwambiri ndipo imakhala ndi magwiridwe antchito abwino otsekera.
Gasket yachitsulo: Yoyenera malo okhala ndi mphamvu yamagetsi komanso kutentha kwambiri, nthawi zambiri imagwiritsidwa ntchito mu zida zoyambirira kapena zida zogwirira ntchito bwino.
Kapangidwe ka zigawo zambiri kokhala ndi chivundikiro choteteza kutentha: Chisindikizo chachitsulo pamwamba + chosateteza kutentha chosakhala chachitsulo pakati + chothandizira chitsulo pansi, zomwe zimapangitsa kuti chitetezo chikhale cholimba.
Zizindikiro zodziwika bwino pambuyo pa kuwonongeka
Fungo la utsi kapena kutentha m'chipinda cha injini;
Phokoso lamphamvu "lotentha" kapena "lophulika" panthawi yopuma kapena yothamanga;
Kutaya mphamvu, kuchuluka kwa mafuta omwe amagwiritsidwa ntchito;
Phokoso lokwera kwambiri la utsi;
Pa milandu yoopsa, izi zingayambitse kutentha kwambiri komanso moto wa mawaya kapena zigawo za pulasitiki zomwe zili pafupi.
Malangizo osinthira
Zizindikiro zikayamba, yang'anani ndikusintha nthawi yomweyo;
Ndikofunikira kuyang'ana ngati pamwamba pa flange ya utsi wa manifold yawonongeka mukasintha;
Ma gaskets okhala ndi mabala achitsulo kapena ma gaskets okhala ndi graphite composite amatha kusankhidwa, zomwe zimapangitsa kuti zikhale zolimba kwambiri;
Mukayika, samalani ndi kulimbitsa mabotolo malinga ndi mphamvu yomwe yatchulidwa kuti mupewe kutayikiranso chifukwa chomangika kwambiri kapena kusakhala kolimba mokwanira.
Ngati gasket ya exhaust manifold yawonongeka, imatha kuyambitsa zizindikiro zingapo zodziwikiratu, makamaka zomwe zimakhudza magwiridwe antchito otseka, magwiridwe antchito amagetsi, ndi makina otulutsa utsi a galimotoyo. Kutengera ndi chidziwitso chaposachedwa cha anthu, zizindikiro zodziwika bwino ndi izi:
Zizindikiro zazikulu za matenda
Kutuluka koonekeratu ndi phokoso losazolowereka: Pamene gasket yawonongeka, chisindikizo cha makina otulutsa mpweya chimalephera, ndipo mpweya wotentha wotulutsa mpweya umatuluka m'dera lowonongeka, zomwe zimapangitsa kuti phokoso likhale losalekeza "lotentha" kapena "lophulika", makamaka panthawi yopuma, kuthamanga, kapena pamene accelerator ikutulutsidwa. Kuchepetsa mphamvu ya injini: Kutuluka kwa mpweya kumayambitsa kupanikizika kosazolowereka kwa mpweya wotulutsa mpweya, zomwe zimakhudza momwe turbocharger imagwirira ntchito kapena kuwerenga kwa sensa ya okosijeni, zomwe zimapangitsa kuti chisakanizocho chiwonetsedwe "chopanda mphamvu kwambiri", zomwe zimapangitsa kuti liwiro liziyenda bwino komanso liwiro liziyenda pang'onopang'ono.
Utsi ndi fungo m'chipinda cha injini: Utsi wosayaka umatuluka m'chipinda cha injini, ndipo fungo loipa la "kuyaka kosakwanira" limapezeka, ndipo utsi ungawonekere.
Deta ya sensa ya okosijeni yosazolowereka: Kutayikira kwa mpweya kumasokoneza chiweruzo cha sensa ya okosijeni pa kuchuluka kwa mpweya wotuluka mu utsi, zomwe zimapangitsa kuti ECU isaganize molakwika za chiŵerengero cha mpweya ndi mafuta, motero imakhudza njira yopangira mafuta, kukulitsa kusowa kwa mphamvu komanso kuyambitsa zochitika za "kutupa" kapena "siren".
Kusintha kwa ma transmission odziyimira pawokha kosazolowereka: Mu mitundu ina ya ma transmission odziyimira pawokha, chifukwa cha kusagwira ntchito bwino kwa injini, TCU (Transmission Control Unit) nthawi zambiri imatha kuchepetsa mphamvu kuti iteteze injini, zomwe zimapangitsa kuti injiniyo isunthe.
Kusintha kwa mawonekedwe m'malo olumikizirana: Yang'anani malo olumikizirana pakati pa gawo lakutsogolo la chitoliro chotulutsa utsi ndi manifold a utsi, ndipo maenje ang'onoang'ono kapena ma deformation okhala ndi malo osafanana pamwamba pa flange nthawi zambiri amapezeka .
Zoopsa ndi malingaliro omwe angakhalepo
Ngati sichinayankhidwe kwa nthawi yayitali, chingayambitse:
Kulephera kwa turbocharger (ngati ili ndi turbocharger);
Kutentha kwambiri kapena kuwonongeka kwa chosinthira cha njira zitatu;
Kupitirira miyezo ya utsi wotulutsa mpweya, kulephera kupititsa patsogolo kuwunika kwapachaka.
Malangizo: Zizindikiro zomwe zili pamwambapa zikapezeka, tikukulimbikitsani kupita ku malo okonzera akatswiri mwachangu kuti mukayang'ane makina otulutsira utsi, makamaka kuyang'ana momwe gasket ilili pamalo olumikizirana pakati pa manifold otulutsa utsi ndi gawo lakutsogolo la chitoliro chotulutsira utsi. Kusinthitsa ndi zida zatsopano ndikofunikira ngati pakufunika kutero. Yang'anani nthawi zonse chitoliro chotulutsira utsi kuti muwone ngati pali phokoso kapena utsi wosayenera, makamaka mukayendetsa galimoto yodzaza katundu wambiri (monga kuyendetsa galimoto yokwera phiri, pogwiritsa ntchito mabuleki otulutsa utsi).
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
