Kodi valavu ya gulugufe ndi chiyani?
 

Pogwiritsa ntchito injini yamafuta amoto, valavu yampweya ndi gawo lofunikira kwambiri pakulowetsa mpweya. Mwanjira ina, imayang'anira kuchuluka kwa mpweya womwe umalowa m'chipinda choyaka moto cha injini yamagalimoto.

Monga zomangamanga, valavu yamagulugufe ndiyosavuta. Imakhala ndi thupi lozungulira, lomwe limakhala ndi valavu yamagulugufe ("gulugufe") yozungulira mozungulira ndi sensa.

Kodi valavuyi ili kuti ndipo imagwira ntchito bwanji?
 

Popeza ntchito yaikulu ya valve throttle ndi kulamulira ndi kulamulira kuchuluka kwa mpweya wolowa m'chipinda choyaka moto, pangakhale malo amodzi okha - pakati pa fyuluta ya mpweya ndi zochulukirapo.

Makina othamangitsa akapanikizika, mbale mu valavu imatseguka ndikulola mpweya kulowa mchipinda choyaka moto. Chotupacho chikamasulidwa, mbaleyo imatseka ndipo "imabanika" mpweya ukuyenda mchipinda choyaka moto. Kuchuluka kwa mpweya wabwino womwe valavu imalowetsa m'chipinda choyaka moto kumayendetsa kuthamanga kwa injini, zomwe zikutanthauza kuti imayendetsanso liwiro lagalimoto.

Mitundu ndi magwiridwe antchito a valavu wapakhosi
 

Mtundu wa valavu umatsimikizika ndi kapangidwe kake, kachitidwe kake ndi momwe amagwirira ntchito. Kutengera izi, titha kunena kuti pali mitundu iwiri yamatayala agulugufe: ogwiritsidwa ntchito ndi zamagetsi.

Mavavu fulumizitsa ndi galimoto makina
 

Magalimoto achikulire nthawi zambiri amakhala ndi mavavu agulugufe. Chomwe chimadziwika ndi magwiridwe antchito awa ndikuti cholembera cholumikizira chimalumikizidwa mwachindunji ku valavu kudzera pachingwe chapadera.

Mphamvu yamagetsi yamagetsi yamagetsi ndi iyi:

Makina othamangitsira akapanikizika, makina azitsulo ndi zingwe amayatsidwa omwe amatsegula valavu. Zotsatira zake, mpweya umayamba kuyenda mu kachitidweko ndikupanga mafuta osakanikirana ndi mpweya.

Mukamapereka mpweya wochuluka, m'pamenenso mumapereka mafuta ambiri komanso kuti galimoto iyende mofulumira. Makina othamangitsira akatulutsidwa, valavu yampweya imatseka, kulola mpweya wabwino kulowa mkati, ndikupangitsa kuti injini ichepetse galimotoyo.

Zamagetsi zamagetsi zamagulugufe
 

Mavavu amtunduwu samangokhala amakono kuposa amakina, komanso amagwiranso ntchito mosiyanasiyana. Mosiyana ndi ma valve amagetsi, mavavu amagetsi safuna kulumikizana ndi makina kuti achite. M'malo mwake, amagwiritsa ntchito zowongolera zamagetsi zomwe zimapangitsa kuti mpweya uziyenda bwino.

Mavuto ofala kwambiri ndi mavavu agulugufe
 

Monga gawo lirilonse la galimoto kapena makina, valavu yokhotakhota, yamagetsi kapena yamagetsi, imatha. Mwamwayi, izi ndizosowa chifukwa zinthuzi ndizolimba komanso zolimba, ndipo ndizotheka kuti simuyenera kusintha valavu mukuyendetsa.

Komabe, ndizothandiza kudziwa zizindikilo zazikulu zomwe zikuwonetsa kuti kupuma sikugwira bwino ntchito.

Kulephera kwa injini
Madipoziti amamanga mkati mwa throttle body (vavu) pakapita nthawi, zomwe zimatha kuchepetsa kapena kusokoneza kutuluka kwa mpweya wabwino kulowa muchipinda choyaka. Izi zikachitika, mafuta ndi mpweya sizingagwirizane bwino, zomwe zimayambitsa kusalinganika kwamafuta - kusakaniza kwa mpweya ndi injini sizigwira ntchito bwino.

Madipoziti a kaboni amachita chimodzimodzi ndi dothi lomwe lapeza. Amadziunjikira pamakoma opumira ndikusokoneza atomization ya mpweya wosakaniza wamafuta.

Vuto la sensa
Ngati sensa yomwe ili m thupi lakuphulika yawonongeka, imatumiza zolakwika pakompyuta yamagalimoto, zomwe zimapangitsa kusakanikirana bwino kwa mpweya ndi mafuta mchipinda choyaka moto.

Low rpm ndi ulesi
Chotupa chimatsekedwa kapena chakutha, chimodzi mwazizindikiro zodziwika bwino za kulephera ndiko kulephera kuyendetsa galimoto. Ngakhale mutayesetsa chotani, kuthamanga kwagalimoto kudzakhala pakati pa 500 ndi 1000 ndipo injini izidzanjenjemera kwambiri komanso mokweza kuposa kale.

Kugwiritsa ntchito mafuta kwambiri
Ngati mafuta akugwa mwadzidzidzi ndipo galimoto sichiyenda bwino, ichi ndi chizindikiro china kuti pali vuto la kupindika.

Kodi valavu yamagetsi ingakonzedwe?
 

M'malo mwake, valavu ikasweka kapena ikutha, siyingakonzedwe ndipo iyenera kusinthidwa ndi yatsopano. Mwamwayi, mavuto ake ambiri amatha kuthetsedwa ndi kuyeretsa. Opanga amalimbikitsa kutsuka valavu iliyonse makilomita 30-40, ngakhale simunazindikire zina mwazizindikiro zomwe tazilemba.

Kuyeretsa sikovuta kwenikweni, ndipo ngati muli ndi nthawi, chikhumbo, ndi zida zingapo zoyambira, mutha kuzichita nokha.

Momwe mungatsukitsire valavu yamagulugufe?
 

Zomwe mukufunikira kuyeretsa valavu ndi chotsukira chapadera, chopukutira ndi chopukutira mutu. Ngati ali pafupi, tsatirani izi:

Imani injini kuti mupeze payipi yochulukirapo. Tsatirani mpaka mufike pa bulaketi yomwe imalumikiza ndi fulumizitsa
Gwiritsani ntchito screwdriver kumasula kulumikizana ndikuchotsa payipi.
Ngati pali maipi ena, chotsani
Musanafeze valavu ndi sopo, fufuzani komwe kuli sensa ndipo samalani kuti musapopera.
Spray ndi detergent ndikudikirira mphindi zochepa
Lumikizani ma payipi onse ku thupi lopumira.
Yendetsani mayeso. Yambitsani injini ndikuyenda mozungulira malowa. Valavu ikatsukidwa bwino, injini iyenera kuyendetsa bwino ndipo utsi wotuluka munthawiyo uyenera kukhala wamtundu wabwinobwino.
Kuyeretsa valavu yampweya

Ngati palibe chosintha, ndiye kuti muyenera kusintha valavu.

Momwe mungasinthire valavu yamagulugufe?
 

Zida zomwe mungafune ngati mungasankhe m'malo mwazokha: zopangira zoyeserera, zolumikiza, seti ya zingwe ndi zoyatsira.

Zachidziwikire, muyenera kugula valavu yatsopano yamagulugufe musanayambe ntchito yosinthana. Mutha kudziwa kuti ndi chiyani poyang'ana buku lamagalimoto anu kapena mwa kufunsa malo ogulitsira magalimoto komwe mukufuna kugula gawo ili.

Chomaliza chomwe mukufuna ndi zovala zoteteza. Kawirikawiri, zovala zabwino zogwirira ntchito, zikopa zamagalimoto ndi magolovesi ndizokwanira kuti mukhale otetezeka.

Masitepe oyendetsa ma valve
 

• Imani injini, pezani valavu ya fulumizitsa ndikudula zingwe zonse ndi ma payipi olumikizidwa.
• Onetsetsani kuti muzimitsa magetsi ndi magetsi otenthetsera
• Chotsani malo opumira
• Chotsani mabatani onse omwe amakhala ndi thupi lopumira
• Nthawi zambiri pamakhala anayi ndipo amalumikiza thupi lopindika mozungulira.
• Mukamasula ma bolts, muwonanso chisindikizo. Samalani ndi izi chifukwa mudzakhala mukuzigwiritsa ntchito mukayika valavu yatsopano
• Chotsani valavu yakale ya fulumizitsa ndikutsuka malowo bwino.
• Ikani thupi latsopano la valavu. Onetsetsani kuti chidindocho chilipo, ikani valavu, ikumangirireni kolimba ndikulimbitsa ma bolts.
• Lumikizani zigawo zonse motsatizana pakutsitsa
• Kusintha valavu yampweya

Zofunika. Musanayese kusintha valavu monga momwe takuwonetsani, onetsetsani kuti malangizowa ndi olondola pagalimoto yanu. Ngati zikukuvutani kuthana ndi valavu yanu yam'manja, ndibwino kuti mulumikizane ndi akatswiri, komwe adzasinthire mwachangu komanso mwaluso kwambiri.

Mafunso ndi Mayankho:

Kodi valavu ya gulugufe ndi chiyani? The throttle valve ndi mbali ya dongosolo lolowera galimoto. Imayendetsa kayendedwe ka mpweya umalowa. Mu classic version, imayimiridwa ndi damper yozungulira, yosinthika ndi chingwe.

Dzina lina la valavu ya throttle ndi chiyani? The throttle, valve throttle, valve throttle - zonsezi ndi mayina a makina omwewo omwe amasintha malo othamanga a thirakiti.
