Mapampu a Vacuum amagwira ntchito

Ndi liti pamene Pumpu ya Vacuum imapindulitsa injini?

A pompopompo, kawirikawiri, ndi phindu lowonjezera ku injini iliyonse yomwe imagwira ntchito kwambiri kuti ipangitse kuphulika kwakukulu. Pampu ya vacuum imawonjezera mphamvu zamahatchi, kuwonjezera moyo wa injini, kusunga mafuta oyeretsa kwa nthawi yayitali.

Kodi Mapampu A Vacuum Amagwira Ntchito Bwanji?

Pampu ya vacuum imakhala ndi cholowera cholowera ku chivundikiro chimodzi kapena zonse ziwiri, nthawi zina poto yachigwa. Imayamwa mpweya kuchokera ku injini, motero imachepetsakuthamanga kwa mpweyakumangidwa kopangidwa ndi kuwomba chifukwa cha mpweya woyaka womwe umadutsa mphete za pistoni mu poto. Mapampu a vacuum amasiyana kuchuluka kwa mpweya (CFM) omwe amatha kuyamwa kotero kuti VACUUM yomwe pampu ingathe kupanga ndi MALIRE ndi kuchuluka kwa mpweya womwe ungayende (CFM). Utsi wochokera ku pampu ya vacuum umatumizidwa ku aBREAther thankiyokhala ndi fyuluta pamwamba, yomwe imapangidwira kusunga madzi aliwonse (chinyezi, mafuta osagwiritsidwa ntchito, mafuta obadwa ndi mpweya) omwe amayamwa mu injini. Mpweya wotulutsa mpweya umapita kumlengalenga kudzera mu fyuluta ya mpweya.

Kukula kwa Pampu ya Vacuum

Mapampu a vacuum amatha kuyesedwa ndi kuthekera kwawo kuyendetsa mpweya, mpweya wochuluka wa pampu yotsekemera umatulutsa mpweya wochuluka pa injini yomwe wapatsidwa. Pampu yaing'ono "yaing'ono" ingasonyeze zochepamphamvu ya mpweyakuposa pampu "yachikulu" yopuma. Kuyenda kwa mpweya kumayesedwa mu CFM (ma kiyubiki mapazi pa mphindi), vacuum imayesedwa ndi "ma inchi a Mercury"

Ma injini onse amapanga kuchuluka kwaphulitsa(kutuluka kwa mafuta oponderezedwa ndi mpweya kudutsa mphete kulowa m'dera la poto). Kuwomba kwa mpweya kumeneku kumapangitsa kuti pampupayo ikhale yabwino, pampu ya vacuum "imayamwa" mpweya kuchokera mu crankcase ndi mpweya wake woipa. Kusiyana kwaukonde pakati pa mpweya womwe umayamwa ndi mpope ndi mpweya wopangidwa ndi injini ndikuwomba kumapereka mpweya wothandiza. Ngati mpope siwukulu, wowongoleredwa komanso wokonzedwa moyenera, sungathe kusuntha mpweya wokwanira kuti upangitse kupanikizika koyipa mu crankcase.
