Qhov sib txawv turbine geometry - nws puas zoo dua li qhov geometry ruaj khov?
Txheem
Thawj hom turbochargers tau tswj los ntawm kev siv siab rau lub qhov rooj pov tseg. Thaum lub zog siab txwv tau mus txog, lub valve qhib, tso cai rau cov pa ntau dhau kom khiav mus rau hauv cov pa tawm. Qhov sib txawv turbine geometry ua haujlwm txawv thiab ntxiv nrog rau qhov hu ua. rudders, i.e. oars. Nws yog dab tsi? peb teb!
Dab tsi yog qhov sib txawv geometry turbine?
Raws li tau hais los saum no, turbine geometry hauv VHT compressors (los yog VGT lossis VTG nyob ntawm cov chaw tsim khoom) tuaj yeem kho lossis hloov pauv. Lub tswv yim yog los tswj cov pa hluav taws xob uas tsim los ntawm lub cav kom zoo li sai tau. VNT turbine muaj ib lub nplhaib ntxiv ntawm sab kub. Oars (los yog rudders) muab tso rau ntawm nws. Lub kaum sab xis ntawm lawv qhov sib txawv yog tswj los ntawm lub tshuab nqus tsev vacuum. Cov hniav no tuaj yeem txo lossis nce qhov chaw rau qhov ntws ntawm flue gases, uas cuam tshuam rau qhov ceev ntawm lawv cov dej ntws. Qhov no tso cai rau sab kub impeller kom tig nrawm dua txawm tias nyob twj ywm.
Yuav ua li cas kho thiab hloov pauv geometry turbocharger ua haujlwm?
Thaum lub cav idling los yog nyob rau hauv qhov qis rpm ntau (nyob ntawm seb lub cav sib dhos thiab lub cav loj), muaj cov pa tso pa txaus kom lub turbine los ntawm kev tsim cov boost siab. Turbo lag tshwm sim thaum lub roj pedal yog nias nyuaj ntawm cov geometry turbo units. Qhov no yog ib lub sij hawm ntawm hesitation thiab tsis muaj acceleration tam sim ntawd. Xws li lub turbine tsis tuaj yeem nrawm tam sim ntawd.
Kev hloov pauv geometry turbine ua haujlwm
Qhov sib txawv geometry ntawm lub turbine txhais tau hais tias txawm nyob rau qis rpm, thaum lub cav tsim cov pa roj me me, lub zog siv tau tuaj yeem ua tiav. Lub tshuab nqus tsev vacuum txav lub kauj lub kauj mus rau ib qho chaw kom txo tau cov pa ntws tawm thiab ua kom cov pa tawm nrawm. Qhov no ua rau kev sib hloov ceev ntawm lub rotor thiab kev sib hloov ntawm lub log compression ntawm sab txias. Tom qab ntawd txawm tias tam sim ntawd nias ntawm lub accelerator yam tsis muaj hesitation yuav txhais ua kom nrawm nrawm.
Tsim cov geometry turbocharger sib txawv thiab cov pa turbocharger
Tus neeg tsav tsheb saib lub turbine los ntawm sab nraud yuav tsis pom qhov txawv ntawm ib hom thiab lwm yam. Qhov sib txawv geometry tau muab zais rau ntawm sab kub thiab yuav tsis pom ntawm qhov muag. Txawm li cas los xij, yog tias koj saib ze, koj tuaj yeem pom ntau qhov loj ntawm lub turbine nyob ib sab ntawm lub tso pa tawm. Cov kev tswj ntxiv yuav tsum haum rau hauv. Hauv qee hom VNT turbines, kuj tseem muaj electro-pneumatic tswj li qub nrog ib qho ntxiv stepper lub cev muaj zog, uas tseem pom thaum kuaj xyuas cov khoom siv.
Turbine - hloov pauv geometry thiab nws qhov zoo
Ib qho ntawm qhov zoo ntawm qhov system koj twb paub lawm yog tias nws tshem tawm cov nyhuv ntawm turbo lag. Muaj ntau ntau txoj hauv kev los tshem tawm qhov tshwm sim no, xws li ua kom muaj kev sib xyaw ua ke lossis siv hybrid turbochargers. Txawm li cas los xij, qhov sib txawv ntawm cov turbine geometry ua haujlwm zoo heev hauv cov tsheb uas muaj cov cav me me uas qhov nkhaus torque yuav tsum siab kom ntxov li sai tau. Tsis tas li ntawd, txhawm rau kom cov tub ntxhais nrog lub rotor thiab compression log kom nrawm, lub cav tsis tas yuav tsum tig mus rau qhov siab ceev. Qhov no yog qhov tseem ceeb rau lub neej ntawm chav tsev, uas tuaj yeem tsim lub zog siab tshaj plaws ntawm RPMs qis.
Turbocharger nrog hloov pauv geometry - qhov tsis zoo
Qhov tsis zoo ntawm qhov sib txawv geometry turbine yog:
- loj complexity ntawm tus tsim ntawm lub cuab yeej nws tus kheej. Qhov no ua rau tus nqi ntawm kev yuav khoom thiab rov tsim dua li lub turbine;
- lub vane tswj system yog raug rau kis kab mob.
Kev siv lub tsheb tsis raug (thiab qhov tseem ceeb ntawm lub cav nws tus kheej) tuaj yeem ua rau lub neej luv luv ntawm lub turbocharger. Txhua qhov xau hauv lub tshuab ua kom txias thiab lub siab kuj tseem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv. Hmoov zoo, qhov sib txawv geometry yog regenerated thiab feem ntau tsis tas yuav hloov.
Nws yog ib qho nyuaj kom tsis txhob pom tias qhov sib txawv geometry ntawm lub turbine muaj txiaj ntsig, uas koj yuav txaus siab tshwj xeeb thaum tsav tsheb ncig lub nroog thiab hla. VNT tso cai rau koj los txo cov txiaj ntsig ntawm turbo lag kom zero. Txawm li cas los xij, nyob rau hauv qhov kev tshwm sim tsis ua hauj lwm, nws yog ib qho nyuaj heev los kho qhov qub tsis ntawm cov ntsiab lus regenerated. Txawm hais tias lawv tsis tas yuav tsum tau hloov nrog cov tshiab, lawv nyuaj rau kho dua li cov khoom qub. Kev hloov pauv ntawm kev ua tau zoo tuaj yeem pom, piv txwv li thaum braking. Koj yuav tsum txiav txim siab seb qhov geometry sib txawv yog qhov zoo dua rau koj lub tsheb dua li cov geometry ruaj khov.
