Kodi Chifukwa cha Kuyika kwa Valve ya Injini ndi Chiyani?

Phokoso la valve ndi chiyani?

Galimoto itayambitsidwa, injiniyo imapanga "kudina" kofanana ndi phokoso logogoda lachitsulo, lomwe limathamanga kwambiri injini ikamathamanga. Nthawi zonse, injini siyipanga phokoso lamtunduwu kwa nthawi yayitali. Mapokoso ambiri amapangidwa kwakanthawi kochepa pambuyo pozizira ndikuzimiririka pang'onopang'ono. Ili ndiye phokoso la valavu.

Kodi chifukwa cha kulira kwa valavu ndi chiyani?

Chifukwa chachikulu cholira ma valve ndikulola komwe kumapangidwa pakati pa valavu ya injini njira, zambiri zomwe zimachitika chifukwa chakulephera kwa magawo kapena kusintha kosintha, monga ma camshafts, rocker mikono, ndi ma hydraulic jacks.

Mitundu yambiri yamagetsi tsopano imagwiritsa ntchito ma jekete amadzimadzi, omwe amagwiritsidwa ntchito makamaka kukonza malire omwe amabwera chifukwa cha kuvala kwa makina a valavu. Kusintha kokha kwa ma jack hayidiroliki kumadziwika chifukwa cha mafuta. Ziwalozo zikavekedwa mopitirira muyeso ndikupitilira malire a kusintha kosinthika, phokoso la valavu lidzachitika. Kulephera kwa gawo lama hydraulic jack komanso kulephera kwa kusintha kosinthika kumathandizanso kuti valavu imveke.

Kuchulukitsa kwa valavu mopitilira muyeso, kuphatikiza phokoso pomwe mukuyamba (zowonekeratu pamene galimoto ikuzizira), pali zovuta zina. Monga: kukweza ma valavu kosakwanira, kudya osakwanira, kutulutsa mafuta mosakwanira, mphamvu yama injini yocheperako, komanso mafuta ambiri.

Popeza mtundu uliwonse wamagalimoto ndiwosiyana, zofunikira pakuchotsera ma valve ndizosiyana. Nthawi zambiri, chilolezo chovalikira chodyera chimakhala pakati pa mawaya 15-20, ndipo chilolezo chokhazikika cha valavu chimakhala pakati pa mawaya 25-35.

Pali ubale wotani pakati pa phokoso la valavu ndi mafuta a injini?

Popeza kusintha kosintha kwa hayidiroliki kwa jack kumadziwika ndi kuthamanga kwamafuta, phokoso la valavu limalumikizana ndi mafuta. Zachidziwikire, lingaliro ndiloti injini sikumavala.

1. Kutaya mafuta pang'ono kapena kuchuluka kwamafuta osakwanira

Kuthamanga kwamafuta ochepa, mafuta osakwanira chipinda chamagetsi; kapena mafuta osakwanira, ndi mipata mu jekeseni yamagetsi pomwe mpweya ulowa m'malo amafuta, zimayambitsa phokoso la valavu.

2. Mpweya umalowa mumtsinje wamafuta panthawi yokonza

Anthu ambiri ali ndi zoterezi. Iwo amangomaliza kukonza, ndipo panali phokoso laling'ono la valavu pomwe kuyatsa kunali tsiku lotsatira. M'malo mwake, izi sizachilendo, chifukwa pokhetsa mafuta mumafutawo, mafuta omwe amadutsika amadzaza, ndipo mpweya umatha kulowa panjira yamafuta ndikupangitsa phokoso la valavu. Pakatha nthawi yogwira ntchito, mpweya udzatulutsidwa ndipo phokoso la valavu lidzatha.

3. Mpweya wambiri umasungidwa mu injini

Injini ikakhala kuti yakhala ikugwiritsidwa ntchito kwakanthawi, zopangira kaboni zimachitika mkati. Mpweya wa kaboni ukaunjikira pamlingo winawake, njira zamafuta zimatha kutsekedwa, ndikupangitsa kuti magwiridwe antchito a jack yama hydroli alephereke ndikupangitsa phokoso la valavu.

Momwe mungapewere phokoso la valavu?

Kupewa kulira kwa valavu ndikosavuta kwambiri. Wogulitsa amafunikira kuti azisunga nthawi molingana ndi zomwe wopanga amafuna kuti zisawonongeke injini, zomwe zitha kuchepetsa izi. Ndikofunikanso kusankha mafuta amafuta omwe ali oyenera maginito a injini ndi mamasukidwe akayendedwe a galimoto yanu, ndipo osangoyang'ana mwakachetechete mafuta opangira mafuta otsika komanso otsika.
