Mapaipi agalimoto, monga zida zapakati pamagetsi agalimoto, makina amafuta, ndi makina ozizirira, zimakhudza mwachindunji chitetezo chake, kudalirika kwake, komanso moyo wantchito. Pamene bizinesi yamagalimoto ikupita patsogolo pakuchita bwino kwambiri komanso kutulutsa mpweya wochepa, zofunikira zamagalimoto zamagalimoto zikuchulukirachulukira. Nkhaniyi iwunika zizindikiro zazikulu zogwirira ntchito komanso njira zoyendetsera makina opangira mapaipi agalimoto kuchokera m'njira zitatu: sayansi yazinthu, kapangidwe kake, komanso kusinthasintha kwa chilengedwe.
Kusankha Zinthu Kumatsimikizira Kuchita Zofunikira
Kukhalitsa ndi magwiridwe antchito a mapaipi agalimoto amatsimikiziridwa ndi zinthu zakuthupi. Magalimoto oyendera mafuta{1}nthawi zambiri amagwiritsa ntchito malata kapena mapaipi a aluminiyamu kuti azitha kulimba komanso zopepuka. Mosiyana ndi zimenezi,-makina oziziritsa kwambiri a magalimoto amagetsi atsopano amagwiritsa ntchito zida za nayiloni kapena zitsulo zosapanga dzimbiri kuti zipirire kusinthasintha kwa kutentha komanso dzimbiri. Mwachitsanzo, PA66+GF (galasi-fiber-nayiloni yolimba) yakhala njira yabwino kwambiri yopangira mapaipi amtundu wa injini chifukwa champhamvu kwambiri-kutentha kwake (-kutentha kwa nthawi yayitali kupitirira madigiri 120 ) komanso kusagwedezeka. Komanso, umisiri wokutikira mkati (monga epoxy resin anti{12}}corrosion layers) ukhoza kupititsa patsogolo kulimba kwa chitoliro kuti mafuta asalowe ndi ma oxidation.
Kapangidwe Kapangidwe Kumakulitsa Kugwira Ntchito
Mapangidwe a mapaipi amayenera kulinganiza mphamvu zamadzimadzi komanso kugawa kupsinjika kwamakina. Zomangamanga-zophatikizika zamitundumitundu zokongoletsedwa ndi finite element analysis (FEA) zimathandizira makoma apang'ono (kuchepetsa makulidwe a khoma ndi 15%-20%) kwinaku akusunga mphamvu zolimba. Mwachitsanzo,-kutentha kochuluka kwa makina a turbocharger amagwiritsa ntchito-njira yowotcherera zitsulo zosapanga dzimbiri ziwiri. Mkati mwake ndi chromium yosamva kutentha-yopanda chromium-nickel alloy, ndipo gawo lakunja limakutidwa ndi zokutira za ceramic zomwe zimachepetsa kutentha komanso kuteteza mawaya ozungulira. Mapangidwe osindikizira a cholumikizira mwachangu amadalira zida zapadera monga fluororubber (FKM) kapena perfluoroelastomer (FFKM) kuwonetsetsa kuti ntchito yopanda kutayikira pakutentha koyambira -40 digiri mpaka 250 digiri.
Kusinthasintha Kwachilengedwe Kumakulitsa Malire Ogwiritsa Ntchito
Mapaipi amakono amagalimoto amayenera kuthana ndi zovuta zogwirira ntchito: kutsika kwa mpweya m'madera otsetsereka kungayambitse kupanikizika kwa nthunzi yamafuta, chinyezi chambiri m'malo otentha kumatha kufulumizitsa kuwonongeka kwa zida zachitsulo, ndipo malo ozizira kwambiri amafunikira kusinthasintha kwa mapaipi kuti apewe kuwonongeka kwamphamvu. Pofuna kuthana ndi mavutowa, mainjiniya adapanga makina owongolera mapaipi{1}}amene amagwiritsa ntchito{2}}malo olumikizirana ma bellows omangika kuti azitha kukulitsa kutentha ndi kufinya, ndipo amagwiritsa ntchito ma nano{3}}osinthidwa ma polima kuti achepetse{4}}kutentha kocheperako. Deta yoyesera ikuwonetsa kuti mapaipi opangidwa mwapadera a polytetrafluoroethylene (PTFE)-amakhala ndi mizere yopitilira 85% ya kusinthasintha kwawo koyambirira ngakhale pa -60 digiri.
M'tsogolomu, ndi kuphatikizika kwaukadaulo wowunika wanzeru, mapaipi anzeru okhala ndi mphamvu zophatikizika / masensa otentha adzakhala akukula. Ndemanga zenizeni-za nthawi yeniyeni sizimangopereka chenjezo lofulumira la zinthu zomwe zingalephereke komanso zimapatsanso zinthu zofunika kwambiri pakuwongolera mphamvu zamagalimoto. Kupambana kosalekeza pakugwira ntchito kwa mapaipi agalimoto nthawi zonse kwakhala maziko oyambira aukadaulo wamagalimoto.
