Ndife akatswiri pazigawo za injini zapamwamba kwambiri.
Chilankhulo
Pamene chimodzi kapena zingapo za mavavuwa zawonongeka, zotsatira zake zikhoza kuchepetsedwa mphamvu ndi mafuta ochepa, kapena ngakhale kulephera kwathunthu kwa injini.
Mitundu iwiri yodziwika bwino ya kulephera kwa ma valve ndi ma valve opindika / osweka ndi ma valve oyaka.
Ma valve omwe ali pamutu wa silinda ndi gawo lofunika kwambiri la injini ndipo amapanikizika kwambiri, amatsegula ndi kutseka mpaka maulendo 2,500 pa mphindi imodzi pansi pa ntchito yabwino.

MAVAVU APITA
▶Mavavu amalephera kwambiri ndi kupindika kapena kusweka chifukwa chokhudzana ndi pisitoni. Vavu yogwira pamwamba pa pisitoni imayambitsidwa ndi unyolo wanthawi / lamba wosweka komanso kulumikizana kosayenera kwa injini chifukwa chosayika bwino lamba watsopano ndi unyolo.
▶Vavu yopindika pamwambapa ndi chifukwa chakuthyoka kwa lamba wa synchro wotopa. Tepi yanu yolunzanitsa sikhala mpaka kalekale ndipo iyenera kusinthidwa malinga ndi malangizo a wopanga.
MAVAVU OTCHA
▶ Mtundu wina wa kulephera kwa ma valve ndi kupsa ndi ma valve. Kwenikweni, izi zimachitika chifukwa cha kuthawa kwa gasi woyaka ngati sunasindikizidwe bwino pakati pa valve ndi mpando wa valve.
▶Gasi woyaka moto umadutsa mu valve ndikuyamba kuyaka m'mphepete mwa valavu, zomwe zimatha kuipiraipira pakapita nthawi ngati sizinakonzedwe.
▶Mavavu oyaka amatha kuyambitsa mavuto komanso kugwiritsa ntchito mafuta. Kuthamanga kosasunthika kosagwira ntchito, kuchepa kwa mphamvu, kuwombera kumbuyo, ndi moto ndi zizindikiro zonse za kutentha kwa valve.
Zifukwa zomwe zingayambitse kutentha kwa valve ndi:
▶Kutentha kwambiri komweko.
▶Gasi woyaka amatuluka kudzera mu valve ndikukhazikika pamalo amodzi.
▶Ma valve osakhazikika pampando wakumutu wa silinda.
▶Kusazizira kokwanira ndi chifukwa china, popeza gawo loziziritsira mutu wa silinda latsekeka.
▶Kuchotsa ma valve molakwika kumatha kuyika pachiwopsezo chosindikizira ndikupangitsanso kulephera kotere.
Kodi mungapewe bwanji zolephera zotere?
▶ Khalani ndi makina oziziritsira aukhondo kuti injini isatenthe kwambiri, gwiritsani ntchito mafuta abwino kuti musamachulukitse mpweya pampando wa valve, ndipo samalani ndi makina anu nthawi zonse kuti aone ngati ma valve atuluka moyenerera.
▶Kusankha valavu ya injini yapamwamba kungakuthandizeni kupewa izi. Kampani yathu ya 1D, ndi akatswiri opanga ma valve, akhoza kukupatsirani valavu yoyenera ya injini yanu, yapamwamba komanso mtengo wotsika mtengo.
