Pierburg yakhala ikupanga mapampu opumira mpweya (vacuum pumps) olimbikitsira mabuleki kwa zaka zambiri. Ndi mtundu wa EVP40 womwe ulipo, wogulitsayo akupereka njira yamagetsi yomwe imagwira ntchito nthawi iliyonse yomwe ikufunika ndipo imakhazikitsa miyezo yapamwamba pankhani ya kulimba, kukana kutentha komanso phokoso.
EVP40 ingagwiritsidwe ntchito m'magalimoto amagetsi ndi a hybrid komanso m'magalimoto okhala ndi mizere yamagetsi yachikhalidwe. Malo opangira ndi fakitale ya Pierburg ku Hartha, Germany, ndi mgwirizano wa Pierburg Huayu Pump Technology (PHP) ku Shanghai, China.
Pa injini zamakono zamafuta, pampu yamagetsi yotulutsa mpweya imapereka vacuum yokwanira kuti igwire bwino ntchito popanda kutayika kwa mphamvu kwa makina. Mwa kupangitsa pampu kukhala yosadalira injini, makinawa amalola kuti ntchito ikule bwino, kuyambira pa nthawi yoyambira/kuimitsa (kuyenda) mpaka pa nthawi yoyendetsa magetsi (EV mode).
Mu galimoto yamagetsi yaing'ono ya premium-class (BEV), pampuyo inachita bwino kwambiri poyesa mapiri pamsewu wa Grossglockner Alpine ku Austria.
Pakupanga kwa EVP 40, Pierburg adagogomezera kudalirika ndi moyo wautali, popeza kuti kuyendetsa bwino galimoto kuyenera kutsimikizika nthawi zonse ndipo makina oyendetsera mabuleki makamaka ndiwo ofunika kwambiri. Kulimba ndi kukhazikika zinalinso nkhani zazikulu, kotero pampuyo idayenera kudutsa pulogalamu yayikulu yoyesera pansi pa mikhalidwe yonse, kuphatikizapo mayeso a kutentha kuyambira -40 °C mpaka +120 °C. Kuti igwire bwino ntchito, mota yatsopano ya burashi yopanda magetsi idapangidwa mwapadera.
Popeza pampu yamagetsi yotulutsa mpweya imagwiritsidwa ntchito m'magalimoto amagetsi osakanikirana komanso m'magalimoto okhala ndi mizere yamagetsi, phokoso lopangidwa ndi makina opopera mpweya liyenera kukhala lotsika kwambiri kotero kuti silingamveke poyendetsa galimoto. Popeza pampu ndi injini yolumikizidwa zinali chitukuko chathunthu mkati, njira zomangira zolunjika zitha kupezeka ndipo zinthu zodula zochotsera mpweya wogwedezeka zimapewedwa ndipo motero makina onse opopera mpweya amawonetsa bwino kwambiri kuchotsera phokoso loyendetsedwa ndi kapangidwe kake komanso kutulutsa phokoso lochepa mumlengalenga.
Valavu yosabwezera yolumikizidwa imapereka phindu lowonjezera kwa kasitomala, zomwe zimapangitsa kuti kuyika EVP mgalimotoyo kukhale kosavuta komanso kotsika mtengo. Kukhazikitsa kosavuta komwe sikudalira zigawo zina kumathandiza kuthetsa mavuto omwe amabwera chifukwa cha malo ochepa oyika.
Chiyambi: Mapampu otulutsa mpweya omwe amalumikizidwa mwachindunji ndi injini yoyaka moto ndi otsika mtengo, koma ali ndi vuto loti amayenda mosalekeza nthawi zonse akamayendetsa galimoto popanda kufunikira, ngakhale pa liwiro lalikulu, kutengera momwe imagwirira ntchito.
Komano, pompu yamagetsi yotulutsa mpweya imazimitsidwa ngati mabuleki sakugwiritsidwa ntchito. Izi zimachepetsa kugwiritsa ntchito mafuta ndi utsi woipa. Kuphatikiza apo, kusakhalapo kwa pompu yamakina kumachepetsa katundu pamakina opaka mafuta a injini, chifukwa palibe mafuta ena owonjezera omwe amapaka mafuta pa pompu yotulutsa mpweya. Chifukwa chake, pompu yamafuta imatha kuchepetsedwa, zomwe zimapangitsa kuti chingwe choyendetsera galimoto chigwire bwino ntchito.
Ubwino wina ndi wakuti kuthamanga kwa mafuta kumawonjezeka pamalo oyamba oyikapo pampu ya vacuum yamakina—nthawi zambiri pamutu wa silinda. Ndi ma hybrids, ma hybrids, ma vapor amagetsi amathandizira kuyendetsa magetsi onse ndi injini yoyaka moto itazimitsidwa, pomwe akusunga mphamvu yonse ya mabuleki. Ma pompo amenewa amalolanso njira yogwirira ntchito "yoyenda" momwe chingwe choyendetsera galimoto chimazimitsidwira ndipo mphamvu yowonjezera imasungidwa chifukwa cha kuchepa kwa kukana mu chingwe choyendetsera galimoto (ntchito yowonjezera yoyambira/yoyimitsa).
