Kodi pampu yamagetsi yotulutsa mpweya wamagetsi yagalimoto ndi chiyani?
Pumpu yamagetsi ya vacuum yagalimoto (EVP) ndi zida zofunika kwambiri zamagalimoto, zomwe zimagwiritsidwa ntchito makamaka mu dongosolo la mabuleki agalimoto, popopera vacuum kuti iwonjezere mphamvu ya mabuleki. Pumpu yamagetsi ya vacuum imalumikizidwa ndi pumpu yolimbikitsira vacuum kuti ichotse vacuum, kotero kuti zipinda ziwiri za pumpu yolimbikitsira vacuum zimapanga kusiyana kwa kuthamanga kwa mpweya umodzi, motero zimawonjezera mphamvu ya mabuleki. Imatha kuyang'anira kusintha kwa vacuum mu supercharger mothandizidwa ndi masensa a vacuum kuti atsimikizire kuti pali mphamvu yokwanira yolipirira pansi pa mikhalidwe yosiyanasiyana yoyendetsera, zomwe zimagwirizana ndi chitetezo cha galimoto.
Mfundo yogwirira ntchito ya pampu yamagetsi yotulutsa mpweya ndikupereka mphamvu kudzera mu injini kuti iyendetse injini pa thupi la pampu kuti igwire ntchito yoyendetsa pisitoni ndikupanga vacuum. Ntchito yake ndikupanga kupanikizika koyipa ndikuwonjezera mphamvu yomangira. Mphamvu yomangira mpweya imadalira kuchuluka kwa vacuum, ndiko kuti, chiŵerengero cha kupanikizika koyipa mu silinda yotsitsimutsa ndi kupsinjika kwakunja kwamlengalenga. Mapampu amagetsi otulutsa mpweya nthawi zambiri amagwirizanitsidwa mwachindunji ndi ma brake signals, ndipo zoyambitsa ndi kuyimitsa zimagwirizanitsidwa ndi ma brake signals kuti ziwongolere mphamvu yomangira mpweya kosalekeza .
Mapampu amagetsi otulutsa mpweya amagwiritsidwa ntchito m'magalimoto amagetsi, injini zamafuta okhala ndi turbocharged ndi injini zamafuta. Mu injini zamafuta, imalowa m'malo mwa mapampu achikhalidwe otulutsa mpweya kuti asunge mphamvu. Kuphatikiza apo, pampu yamagetsi yotulutsa mpweya imatanthauzanso nsanja yamagalimoto amagetsi (EVP), yomwe ndi kapangidwe ka chassis kapena zomangamanga zomwe zimapangidwira magalimoto amagetsi, zomwe zimaphatikizapo zinthu zofunika monga mabatire, ma mota ndi makina amagetsi kuti akonze magwiridwe antchito agalimoto, chitetezo ndi magwiridwe antchito, kuchepetsa ndalama ndikuwonjezera kukula kwa magalimoto.
Ntchito yaikulu ya pampu yamagetsi ya vacuum yamagalimoto ndikupereka mphamvu ya vacuum ya dongosolo la mabuleki kuti zitsimikizire kuti galimotoyo ikhoza kupereka mphamvu zokwanira pamikhalidwe yosiyanasiyana yogwirira ntchito.
Udindo weniweni wa pampu yamagetsi yotsukira mpweya m'galimoto
perekani mphamvu ya vacuum : pampu yamagetsi ya vacuum kudzera mu injini, imapanga mphamvu yoipa, imapangitsa mphamvu ya mabuleki kukhala yotsika. Mu magalimoto amagetsi, popeza palibe injini yachikhalidwe yopereka gwero la vacuum, pampu yamagetsi ya vacuum imakhala yofunika kwambiri kuti ipereke mphamvu ya vacuum pampu yayikulu ya mabuleki ndikuwonetsetsa kuti dongosolo la mabuleki likugwira ntchito bwino.
Kuwongolera magwiridwe antchito a mabuleki ndi chitetezo: pampu yamagetsi yotulutsa mpweya imatha kusintha liwiro la mabuleki komanso kukhazikika, kuletsa mabuleki mwachangu komanso modalirika nthawi yadzidzidzi, ndikukweza kwambiri magwiridwe antchito achitetezo chagalimoto. Imayang'anira kusintha kwa vacuum mu booster kudzera mu vacuum sensor kuti iwonetsetse kuti mphamvu yokweza mphamvu ikuyenda bwino pamikhalidwe yosiyanasiyana yoyendetsera.
Yoyenera mitundu yosiyanasiyana: Pampu yamagetsi yotulutsa mpweya ndi yoyenera magalimoto odziyimira okha, magalimoto a injini ya turbocharged ndi magalimoto amagetsi. Ingagwiritsidwe ntchito osati pamakina otulutsa mphamvu ya hydraulic okha, komanso pamakina otulutsa mphamvu ya pneumatic kuti ipereke mphamvu yokhazikika ya vacuum, popanda liwiro la injini.
Mfundo yogwirira ntchito ya pampu yamagetsi yotulutsa mpweya
Pampu yamagetsi yotulutsa mpweya imapangidwa makamaka ndi injini, thupi la pampu, rotor ndi tsamba ndi zina. Pakugwira ntchito, injiniyo imayendetsa rotor kuti izungulire, tsamba lomwe lili pa rotor limayenda m'thupi la pampu, ndipo vacuum imachotsedwa ndikutulutsidwa mwa kusintha voliyumu ya thupi la pampu nthawi ndi nthawi. Galimoto ikayima, pampu yamagetsi yotulutsa mpweya imapereka mphamvu yofunikira ya brake booster popompa vacuum, kuti ichepetse liwiro kapena kuyimitsa galimotoyo.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&750 zolandiridwa kugula.
