Valavu Yolowera: "Woyang'anira Kupuma" wa Injini ndi Kasamalidwe ka Zolakwika
Mu makina oyendetsera injini ya galimoto, valavu yolowera imaonedwa ngati "woyang'anira kupuma" wapakati, ndipo momwe imagwirira ntchito zimakhudza mwachindunji mphamvu ya injini, kugwiritsa ntchito mafuta, komanso kukhazikika kwake. Sikuti ndi gawo losavuta lokha loyimitsa, koma ndi dongosolo lolondola lophatikiza matupi a valavu, ma valavu owunikira, ma valavu a gulugufe, ndi zina zotero. Kudzera mu mgwirizano wogwirizana ndi valavu yotulutsa utsi, imawongolera bwino kayendedwe ka mpweya wolowera, zomwe zimathandiza injini kugwira ntchito bwino pamikhalidwe yosiyanasiyana.
Kuchokera pa ntchito yaikulu, valavu yolowera mpweya imatenga udindo wolamulira kayendedwe ka mpweya. Injini ikakhala kuti sigwira ntchito kapena ikuyenda pa liwiro lotsika, valavu yowongolera nthambi yolowera mpweya imasintha kutalika kwa chitoliro cholowera mpweya kukhala kwakukulu, kulola mpweya kupanga vortex yamphamvu mu chitoliro chachitali, ndikusakaniza ndi mafuta mofanana, motero kuonetsetsa kuti ntchito yolowera mpweya imakhala yokhazikika; pomwe galimoto ikathamanga kwambiri kapena ikalowa mu liwiro lalikulu, kutalika kwa chitoliro cholowera mpweya kudzafupikitsidwa zokha, kuchepetsa kukana kwa mpweya, kulola mpweya wabwino wambiri kulowa mu silinda pakapita nthawi yochepa, kukwaniritsa zofunikira zolowera kuti mphamvu ituluke. Kachiwiri, valavu yolowera mpweya imathanso kuyeza molondola mpweya wolowera mpweya. Imapanga njira yowongolera yotsekedwa yokhala ndi masensa opanikizika ndi ma solenoid valves, omwe amatha kuwongolera molondola chiŵerengero cha mpweya ndi mafuta malinga ndi momwe injini imagwirira ntchito nthawi yeniyeni, kulola kuyaka kwathunthu kwa mafuta ndikuchepetsa kugwiritsa ntchito mafuta moyenera. Kuphatikiza apo, valavu yolowera ili ndi njira zambiri zotetezera chitetezo, monga kutha kutseka njira ya mpweya mkati mwa masekondi 0.3 ngati pachitika ngozi, yokhala ndi kapangidwe kotsekedwa kawiri komwe kumatha kuwongolera kutuluka kwa mpweya kufika pamlingo wotsika kwambiri, ndipo njira yake ya valavu yamagetsi imatha kupirira ma cycle otseguka ndi otseka a 2 miliyoni, kuonetsetsa kuti injini ikugwira ntchito bwino kwa nthawi yayitali.
Komabe, pakapita nthawi, valavu yolowera imayamba kukhala ndi zolakwika zosiyanasiyana, zomwe zimayambitsa mavuto omwe angayambitse galimoto. Zolakwika zomwe zimachitika nthawi zambiri zimaphatikizapo kuchepa kwa mphamvu, kusakhazikika kwa ntchito, komanso kugwiritsa ntchito mafuta molakwika. Pamene valavu yolowera imakakamira pamalo otseguka kwathunthu, mphamvu ya vortex pa idle sikokwanira, zomwe zimapangitsa kuti injini igwedezeke; ngati ikakamira pamalo otsekedwa kwathunthu, kuchuluka kwa idle kumakhala kochepa poyendetsa mwachangu, osati kungopangitsa kuti mphamvu ichepe kwambiri, komanso kumapangitsa kuti kuyaka kwa mafuta kusakwanire, zomwe zimapangitsa kuti mafuta ayambe kugwiritsidwa ntchito kwambiri. Magalimoto ena amathanso kukumana ndi vuto poyambira kapena kusowa kwa yankho lofulumira, chifukwa cha momwe valavu yolowera imakhudzira mtundu wa chisakanizocho. Pakuyamba kozizira, mafuta sangatenthedwe kwathunthu, ndipo kuyankha kofulumira kumakhala kochedwa poyendetsa, ndi mavuto ofunikira kwambiri m'malo okwera. Zolakwika zazikulu za valavu yolowera zingayambitsenso kutulutsa mpweya woipa, ndi mpweya wakuda wotuluka mu chitoliro chotulutsa utsi, nthawi zina limodzi ndi kutuluka kwa fungo la mafuta, komanso ngakhale "kubwerera m'mbuyo" mu chitoliro chotulutsa utsi.
Poyang'anizana ndi zolakwika izi, eni magalimoto ayenera kusamala ndi zizindikiro zachilendo za galimotoyo akamagwiritsa ntchito tsiku ndi tsiku ndikuyang'ana nthawi zonse makina olowera. Pa nthawi iliyonse yokonza, ogwira ntchito yokonza magalimoto angagwiritse ntchito chida chowunikira kuti awone deta yogwira ntchito ya valavu yolowera, ndikuwonanso momwe valavu imagwirira ntchito poyeretsa throttle. Ngati mphete ya rabara ikukalamba, iyenera kusinthidwa pakapita nthawi. Zizindikiro monga kuchepa kwa mphamvu, kugwedezeka kosagwira ntchito, kapena zolakwika zomwe zikukayikiridwa kuti valavu yolowera, ndikofunikira kupita ku malo okonzera akatswiri kuti akakonze kuti apewe mavuto ang'onoang'ono omwe amasanduka zolakwika zazikulu ndikukhudza moyo wa injini.
Valavu yolowera, monga gawo lofunika kwambiri la injini, imalamulira mwakachetechete "kayendedwe ka mpweya" wa injini. Kumvetsetsa ntchito yake ndi zolakwika zomwe zimachitika kawirikawiri kungathandize eni magalimoto kusamalira bwino galimotoyo ndikusunga injini ikugwira ntchito bwino komanso mokhazikika.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
