Kusinthika kwa Turbocharger - chifukwa chiyani kuli bwino kuyika kukonza kwa turbine kwa akatswiri?

M'mbuyomu, ma turbocharger adayikidwa m'magalimoto amasewera, magalimoto, kapena dizilo. Masiku ano, pafupifupi galimoto iliyonse ili ndi turbocharger. Izi zimabweretsa kutulutsa kwakukulu pa lita imodzi ya mphamvu, kuchepetsa kugwiritsa ntchito mafuta komanso kutsata miyezo yotulutsa mpweya. Turbo imaperekanso kusinthasintha kuchokera ku ma revs otsika, kotero ndizothandiza kupeza torque yoyenera poyendetsa galimoto mumzinda, mwachitsanzo. Kodi dongosolo loterolo limagwira ntchito bwanji?

Pamaso pa kusinthika kwa turbocharger ndikofunikira, i.e. mawu ochepa okhudza turbocharger

Makina opangira magetsi omwe amaikidwa m'mainjini oyatsira mkati amapangidwa kuti azipopera gawo lina la mpweya pansi pa kukakamizidwa kulowa m'chipinda choyaka. Zachiyani? Kuchulukitsa kuchuluka kwa oxygen mu unit kumawonjezera mphamvu ya unit. Kuponderezana kwa mpweya kumaphatikizapo kukhazikitsa turbine rotor kuyenda mothandizidwa ndi mpweya wotulutsa mpweya. Mbali ina yake ndi gudumu lopondereza lomwe limayamwa mpweya kuchokera mumlengalenga kudzera mu fyuluta. Kuti mpweya usatenthedwe, umalowa m'kati mwadongosolo, nthawi zambiri amakhala ndi intercooler, i.e. mpweya ozizira. Pokhapokha pambuyo pake m'pamene imalowetsamo zochulukitsa.

Turbocharger ndi kusinthikanso - zomwe zingachitike ndi chiyani?

M'malo mwake, zinthu zambiri zimatha kulephera pakugwira ntchito kwa turbine. Kusinthika kwa turbocharger nthawi zambiri ndikofunikira chifukwa "kumatenga" mafuta. Ngakhale kuti "sadzapereka" mafuta, koma kugwiritsira ntchito mopitirira muyeso kwa mafuta a galimoto ndi maonekedwe a utsi wa buluu kuchokera ku chitoliro chotulutsa mpweya kumalimbikitsa kuyang'ana pa turbine. Kodi mtundu wa utsi umenewu umatanthauza chiyani? Utsi woyera wochokera ku chitoliro chotulutsa mpweya nthawi zambiri umasonyeza kuti zoziziritsa kuzizira zalowa muzitsulo, utsi wabuluu umasonyeza mafuta oyaka moto, ndipo utsi wakuda umangosonyeza mafuta osapsa, i.e. mphuno.

Chifukwa chiyani turbo amadya mafuta?

Zomwe zimagwira ntchito mkati mwake, ndiye kuti, pachimake, zimapaka mafuta. Injini ikazimitsidwa, mphamvu yamafuta imatsika ndipo mafuta ochulukirapo m'matchanelo a kumtunda kwa injiniyo ndipo injiniyo amathamangira ku sump yamafuta. Chifukwa chake, ngati mutayamba mwachangu mutangoyamba, posachedwa mudzadabwa komwe mungapangirenso turbocharger. Chifukwa chiyani? Chifukwa mafuta sangathe kufika kuzinthu zonse zomwe zimafuna mafuta, ndipo rotor idzayamba kuzungulira mofulumira.

Ma turbocharger ang'onoang'ono ndi kusinthikanso - chifukwa chiyani amatsindika kwambiri?

Ma turbos ang'onoang'ono (monga omwe amapezeka mu 1.6 HDI 0375J6, 1.2 Tce 7701477904 kapena 1.8t K03) amakhala ndi moyo wovuta kwambiri, monga pa ntchito, iwo amazungulira pa liwiro la mazana angapo zikwi zosintha pa mphindi. Poyerekeza ndi kusintha kwa 5-7 zikwi pa injini, izi ndizochuluka kwambiri. Chifukwa chake, zolemetsa zomwe zimagwira mkati mwake ndi zazikulu kwambiri ndipo zimalephera mosavuta ngati zitagwiritsidwa ntchito molakwika.

Kusasamala mu mawonekedwe akusintha kwanthawi yayitali kwamafuta ndi kuyendetsa mwaukali kumapangitsa kuti zinthu zozungulira zichotse mafuta m'thupi. Koma silo vuto lokhalo ndi ma turbocharger.

Ndi chiyani chinanso chomwe ma turbine amavutikira - kukonza zida zina za injini

Kuphatikiza pa ma valve, zisindikizo ndi masamba a rotor omwe amatha kusweka, nyumbayo imawonongekanso. Nthawi zina chitsulo chimakhala chochepa kwambiri moti ngakhale kuti chili ndi mphamvu, chimagwa. Pali kutayikira mu dongosolo ndi mpweya, m'malo molowa mu manifold ambiri, umatuluka. Pankhaniyi, kusinthika kwa turbocharger kumakhala m'malo mwa chinthucho ndi chatsopano kapena kuwotcherera.

Mapaddle shifters omwe amawongolera geometry nawonso ndi gawo lofunikira pamapangidwe. Ichi ndi chinthu chaching'ono, koma chofunika kwambiri, ndipo kuwonongeka kwake kumakhudza ntchito ya chipangizo chonsecho. Palinso peyala, i.e. vacuum regulator, yomwe imakhala ndi kasupe ndi nembanemba. Chifukwa cha kutentha kwakukulu, zimatha kuonongeka ndipo kuwongolera kwamphamvu kwamphamvu sikungagwire ntchito bwino.

Dziwani kuti turbine regeneration ndi chiyani

Mwachidule, tikukamba za kubwezeretsanso ku fakitale mwa kusintha magawo owonongeka kapena kukonzanso (ngati n'kotheka). Poganizira zomwe zili pamwambazi zolephera zotheka, kuchuluka kwa ntchito kumakhala kwakukulu. Komabe, nthawi zambiri zimakhala zofanana kwambiri, malinga ndi ndondomeko inayake.

Gawo loyamba pakumanganso turbocharger ndikuchotsa magawo onse kuti awone momwe alili. Choncho, izo zakonzedwa m'malo munthu zigawo zikuluzikulu ndi kuyeretsa. Tiyenera kukumbukira kuti ndi dothi ngati mpweya wotulutsa mpweya womwe ndi chimodzi mwazinthu zomwe zimafupikitsa moyo wa turbine. Kuonjezera apo, kupatsa kasitomala chinthu chodetsedwa pambuyo pa kubadwanso si akatswiri kwambiri. Nazi zigawo za subassembly:

● chowongolera;

● mbale yosindikizira;

● gudumu lopondereza;

● gasket yotentha;

● ng'anjo yolunjika;

● mphete zosindikizira;

● wothamangitsa;

● kugawa;

● casing wa rotor shaft (pachimake);

Makanika amayang'ana momwe zinthu zilili pamwambazi. Mwachitsanzo, masamba akuluakulu a rotor amatha kuthyoledwa, shaft yatha, ndipo masamba osinthika a geometry amawotchedwa. Zonsezi zimafunika kutsukidwa bwino kuti kavalidwe kawongoleredwe.

Turbine ndi kusinthikanso - chimachitika ndi chiyani pambuyo pa kuwotcha?

Pambuyo kutsuka bwinobwino, ndi nthawi kuyeretsa zinthu ndi wothinikizidwa mpweya ndi abrasive mankhwala. Kukonzanso kwa Turbocharger sikuyenera kuphatikizira kuyeretsa kwathunthu kwa magawo onse, komanso kuwapaka ndi anti-corrosion agents.. Chifukwa cha ichi, atayikidwa pa injini, gawo lachitsulo la turbine silidzachita dzimbiri. Kufufuza mozama kumakupatsani mwayi wowona kuti ndi zinthu ziti zomwe zikufunika kusinthidwa ndi zatsopano, zomwe zitha kugwiritsidwabe ntchito bwino.

Chotsatira ndicho kuyeza liwiro. Izi zimakuthandizani kuti muwone ngati zinthuzo zikukwanira bwino kotero kuti sizimalola kuti mafuta alowe mu gudumu loponderezedwa. Ambiri okonda DIY amakhulupirira kuti ndizotheka kumanganso makina opangira magetsi m'garaji yawo. Komabe, izi sizovomerezeka. Sizingatheke kudziwa ngati zinthu zonse zasonkhanitsidwa molondola pambuyo pa msonkhano komanso ngati turbo sifunikira kuyeza. 

Ndi ndalama zingati kubwezeretsa turbine m'galimoto?

Mtengo wa zida zosinthira zimasiyanasiyana ndipo zimatengera chitsanzo. Monga momwe mwawonera kale, palinso zinthu zambiri zomwe zimatha kuwonongeka. Kupatula apo, ntchito ya akatswiri iyenera kuwonjezeredwa pamtengo. Mndandanda wamtengo (nthawi zambiri) umadalira kutchuka ndi mbiri ya msonkhanowo. Komabe, mtengo kukonza ma turbocharger nthawi zambiri amawononga pakati pa 800 ndi 120 mayuro Zachidziwikire, mutha kupeza zotsika mtengo, komanso zotsika mtengo kwambiri.

Ndi chiyani chinanso chomwe chingachitike ndi turbine kuti galimotoyo ikhale yamphamvu kwambiri?

Kupanganso turbocharger palokha ndi njira yabwino yokwaniritsira magwiridwe antchito pafupi ndi fakitale. Ndikothekanso kukulitsa bwalo loponderezedwa mmenemo, zomwe zimaphatikizapo kukonza nyumba yoziziritsa, kuyiyendetsa kumtunda wapamwamba, kapena kungoyisintha ndi yokulirapo. Zoonadi, sizikupanga nzeru kusintha zinthu zoterezi mu injini zosalekeza, chifukwa posakhalitsa chinachake chidzalephera (mwachitsanzo, mayendedwe a clutch kapena shaft). Koma uwu ndi mutu wa nkhani ina.
