Kuwerenga zolemba za VGT turbocharger

Mapu onse a compressor amawunikidwa mothandizidwa ndi njira zomwe zimatengedwa pakuwunika zofunikira.Zitha kuwonetsedwa kuti palibe chophatikizira chomwe chimawonjezera mphamvu ya kompresa pamagalimoto akulu ndikusunga kukhazikika koyambira komanso kuchita bwino pamagetsi ovotera.Izi ndichifukwa chakuchepa kwakukula kwa mapu mukamagwiritsa ntchito cholumikizira cholumikizira.Zotsatira zikuwonetsanso kuti palibe chiwongolero pakuyika kwa ntchito yeniyeni ya choyikapo nyali pomwe cholumikizira chamagetsi chokhala ndi magawo amapangidwe amtundu womwe waperekedwa chikugwiritsidwa ntchito.Kuthamanga kwa ma impeller pamlingo womwe wapatsidwa ndi gawo lokhalo la kusiyana komwe kumachitika pogwiritsa ntchito vaned diffuser.Cholinga cha geometry ya compressor yosinthika imatanthauzidwa ngati kusunga phindu pamagalimoto akulu ndikukulitsa m'lifupi mwamapu kuti ifike pamtunda ndikutsamwitsa kutuluka kwa vaneless diffuser kuti apeze mphamvu pamagetsi ovotera, torque yapamwamba komanso nthawi. ntchito yoboola injini yomwe ikufanana ndi kompresa yoyambira.

Ma compressor atatu osinthika apangidwa ndi cholinga chothandizira kuwongolera kuchuluka kwamafuta pamainjini olemetsa kwambiri pamagalimoto akuluakulu popanda kuwonongeka kwa mphamvu zovoteledwa,

torque yapamwamba, kukhazikika kwamphamvu komanso kulimba.Pachiyambi choyamba, zofunikira za injini pokhudzana ndi siteji ya compressor zatengedwa ndipo malo ogwiritsira ntchito compressor oyenera kwambiri amadziwika.Magalimoto akuluakulu oyendetsa magalimoto aatali amafanana ndi malo ogwiritsira ntchito pamagulu othamanga kwambiri komanso otsika kwambiri.Kutayika kwa kayendedwe ka ndege chifukwa cha mafunde othamanga kwambiri mu makina opangira magetsi a vaneless amatenga gawo lalikulu pamayendedwe awa.

Pofuna kupititsa patsogolo chuma chamafuta popanda kudzipereka pokhudzana ndi zovuta za injini zomwe zatsala, ma geometries osinthika amayambitsidwa kuti awonjezere kukula kwa mapu komanso nthawi yomweyo kutipangitsa kuti tigwire bwino ntchito ndi ma compressor pamlingo wothamanga kwambiri wa ma diffusers ophatikizika.
