I-Pierburg ibilokhu yenza amaphampu e-vacuum for brake booster amashumi eminyaka. Ngemodeli yamanje ye-EVP40, umphakeli unikeza inketho kagesi esebenza ngokufunwa futhi ebeka izindinganiso eziphakeme mayelana nokuqina, ukumelana nezinga lokushisa nomsindo.
I-EVP40 ingasetshenziswa kuma-hybrids nasezimotweni zikagesi kanye nasezimotweni ezinemigqa yokushayela evamile. Izakhiwo zokukhiqiza ziyimboni yasePierburg eHartha, eJalimane, kanye nebhizinisi elihlanganyelwe lasePierburg Huayu Pump Technology (PHP) eShanghai, eChina.
Ezinjinini zesimanje zikaphethiloli, iphampu ye-vacuum kagesi ihlinzeka ngezinga elanele le-vacuum yokubhuleka okuphephile nokulula ngaphandle kokulahlekelwa amandla unomphela kwephampu engumshini. Ngokwenza iphampu izimele enjinini, isistimu ivumela ukwanda okwengeziwe ekusebenzeni kahle, kusukela kumodi enwetshiwe yokuqala/yokumisa (ukuhamba ngomkhumbi) kuya kumodi yokushayela kagesi wonke (imodi ye-EV).
Emotweni kagesi ecwengekile yezinga le-premium (BEV), iphampu ibonise ukusebenza okuhle kakhulu ngesikhathi sokuhlolwa kwe-highland emgwaqeni we-Grossglockner alpine e-Austria.
Eklanyweni ye-EVP 40, i-Pierburg igcizelele ukwethembeka nokuphila isikhathi eside, njengoba ukusebenza kwemoto kufanele kuqinisekiswe ngaso sonke isikhathi futhi uhlelo lokubhuleka lubaluleke kakhulu. Ukuqina nokungaguquguquki nakho kwakuyizinkinga ezibalulekile, ngakho-ke iphampu kwadingeka idlule ohlelweni olubanzi lokuhlola ngaphansi kwazo zonke izimo, okuhlanganisa nokuhlolwa kwezinga lokushisa ukusuka ku -40 °C kuya ku-+120 °C. Ukuze kusebenze kahle okudingekayo, ibhulashi elisha, eliqinile elingenazo izinto zikagesi lakhiwe ngokukhethekile.
Ngenxa yokuthi ipompo ye-vacuum kagesi isetshenziswa ezimotweni ezixubile nasezimotweni zikagesi kanye nasezimotweni ezinemigqa evamile yokushayela, umsindo okhiqizwa isistimu yepompo kufanele ube phansi kakhulu kangangokuthi ungezwakali ngenkathi ushayela. Njengoba iphampu kanye nenjini edidiyelwe bekuwukuthuthukiswa okuphelele kwangaphakathi kwendlu, izixazululo eziqondile zokuziqinisa zingatholakala futhi izinto ezibizayo zokunqamula ukudlidliza zigwenywe futhi yingakho lonke uhlelo lwepompo lubonisa ukunqanyulwa komsindo ophethwe yisakhiwo esihle kakhulu nomsindo okhishwa umoya ophansi.
Ivalvu ehlanganisiwe engabuyi inikeza inani elengeziwe kukhasimende, okwenza kube lula futhi kushibhe ukufaka i-EVP emotweni. Ukufakwa okulula okuzimele kwezinye izingxenye kwenza kube nokwenzeka ukuxazulula izinkinga ngaphandle kwalokho ezibangelwa indawo yokufaka eqinile.
Ingemuva. Amaphampu emishini evacuum ahlanganiswe ngokuqondile nenjini evuthayo, ayabiza kakhulu, kodwa anomuhle wokuthi asebenza ngokuqhubekayo phakathi nokusebenza kwemoto ngaphandle kokufunwa, ngisho nangesivinini esikhulu, kuye ngemodi yokusebenza.
Ngakolunye uhlangothi, iphampu ye-vacuum kagesi iyacishwa uma amabhuleki engasebenzi. Lokhu kunciphisa ukusetshenziswa kukaphethiloli kanye nokukhishwa kwegesi. Ngaphezu kwalokho, ukungabikho kwepompo engumshini kukhulula umthwalo ohlelweni lokugcoba uwoyela wenjini, njengoba kungekho uwoyela owengeziwe ogcoba iphampu ye-vacuum. Ngakho-ke iphampu kawoyela ingenziwa ibe mncane, okubuye kwenyuse ukusebenza kahle komugqa wokushayela.
Enye inzuzo ukuthi umfutho kawoyela ukhuphuka endaweni yokuqala yokufaka iphampu yomshini wokuvala imishini—ngokuvamile ekhanda le-cylinder. Ngama-hybrids, amaphampu evacuum kagesi anika amandla ukushayela okusebenza ngogesi wonke injini evuthayo icishiwe, kuyilapho igcina i-boost egcwele yamabhuleki. Lawa maphampu aphinde avumele indlela yokusebenza "yokuhamba ngomkhumbi" lapho ulayini wokushayela ucishwa khona futhi kulondolozwa amandla engeziwe ngenxa yokuncishiswa kokumelana nomugqa wokushayela (ukusebenza kokuqala/ukumisa okwandisiwe).
