Isihlungi sikawoyela weloli 5801628021 isihlungi sezingxenye zenjiniye-IVECO

Isingeniso sesihlungi samafutha

Isihlungi sikawoyela sitholakala ohlelweni lokuthambisa injini.Enhla nomfula yiphampu kawoyela, kanti ezansi nomfula yizingxenye ezahlukene zenjini ezidinga ukugcotshwa.Umsebenzi wawo ukuhlunga ukungcola okuyingozi emafutheni epanini likawoyela, futhi unikeze i-crankshaft, induku yokuxhuma, i-camshaft, i-supercharger, indandatho ye-piston namanye amapheya ahambayo ngamafutha ahlanzekile, adlala indima yokugcoba, ukupholisa nokuhlanza.Nweba impilo yalezi zingxenye.

Uhlobo

Isihlungi sikawoyela esiyi-centrifugal sinomkhono we-rotor ku-shaft futhi sinezimbobo ezimbili ezinezikhombisi-ndlela ezihlukile zesifutho.Lapho amafutha engena ku-rotor futhi ephuma ku-nozzle, i-rotor ijikeleza ngokushesha ukuze ihlanze amafutha emzimbeni we-rotor.Ukungcola emafutheni ziphonswa nge-centrifugally odongeni lwangaphakathi lwe-rotor, futhi amafutha avela ku-nozzle ageleza abuyele epanini likawoyela.Isihlungi samafutha e-centrifugal sibonakala ngokusebenza okuzinzile, akukho sici sokuhlunga okufanele sishintshwe, inqobo nje uma i-rotor ihlakazwa njalo, ukungcola okufakwe odongeni lwe-rotor kungahlanzwa futhi kusetshenziswe kabusha.Impilo yayo ingalingana neyenjini.Ukushiyeka kwayo kulele esakhiweni esiyinkimbinkimbi, intengo ephezulu, isisindo esisindayo, njll., futhi inezidingo eziphezulu zobuchwepheshe zabasebenzisi.

Izihlungi zikawoyela ezigeleza ngokugcwele, njengokushintshwa, ukuphonswa, ukuhlukaniswa kwe-centrifugal, njll., njengoba kushiwo ngenhla, zihlunga wonke uwoyela ongena ohlelweni.Isihlungi esihlukanisayo sihlunga kuphela u-5% -10% wamafutha ahlinzekwa yiphampu kawoyela.Izihlungi zikawoyela we-split-flow izihlungi ezinhle, ezivame ukusetshenziswa ngokuhambisana nokugeleza okugcwele.Izinjini eziningi ezinamandla aphansi zisebenzisa kuphela izihlungi ezigeleza ngokugcwele, futhi izinjini zikadizili ezinamandla aphakeme kakhulu zisebenzisa imishini yokuhlunga egeleza ngokugcwele kanye ne-split-flow.

ukushiyeka

Kunamaphutha amabili amakhulu, futhi umkhiqizo omusha wenza ukushiyeka, ngakho-ke kuyadingeka ukusebenzisa umkhiqizo omusha oqinile wokuhlunga uwoyela kazibuthe.

Ububi 1: I-60% yokungcola emafutheni iyahlungwa, futhi ukusebenza kahle kokuhlunga kuphansi;

Lokhu kungenxa yokuthi isihlungi sikawoyela esikhona sincike emgodini owodwa wesihlungi sephepha ukuze sinqande futhi sihlunge ukungcola okuyingozi emafutheni.Ama-pores wephepha lokuhlunga amancane, umphumela wokuhlunga ungcono, kodwa ikhono lokudlula uwoyela libi kakhulu.Ukuze uxazulule ukuphikisana ukuthi iphepha elifanayo lokuhlunga alikwazi ukuhlunga kuphela ukungcola kwezinhlayiya, kodwa futhi lenze amafutha anele anikezwe injini ukuze adlule ama-pores.Ngokusho kweHlunga Legatsha le-Internal Combustion Engine Industry Association, izihlungi zikawoyela emakethe zingaklanywa kuphela ukuhlunga ukungcola okungama-60% emafutheni.Leli inani lokuhlunga elitholwe ngemva kwezinkulungwane zokuhlolwa.Ekusetshenzisweni kwangempela, kusekhona u-40% wokungcola okuyingozi okungakwazi ukuhlungwa ngokuphumelelayo isici sokuhlunga iphepha.Phakathi kwalokhu kungcola okungama-40%, ukungcola kwe-ferromagnetic kuncane futhi kuqinile, ngakho-ke iningi lazo ukungcola kwe-ferromagnetic, okuzolimaza injini..

Ububi 2: Ukusebenza kahle kokuhlunga kunguziro ngaphansi kwezimo ezikhethekile;

Kune-valve ye-bypass ezansi kwesisefo sephepha, eklanyelwe ukuqinisekisa ukuthi uwoyela ungazuliswa kahle ubuyele enjinini lapho injini iqalwa ngokubanda nge-viscosity ephezulu kawoyela noma lapho isihlungi sephepha siyingxenye noma ivinjwe ngokuphelele.umzila wokugeleza kawoyela.Lapho uwoyela evula i-valve ye-bypass ngaphansi kwengcindezi yepompo yamafutha, uwoyela ojikelezayo ubuyela enjini nge-valve yokudlula ngeke nje kuphela ahlungwe isici sokuhlunga iphepha, kodwa futhi azohlunga izinhlayiya ezinkulu zokungcola kuhlungwe ngesihlungi sephepha.Iphindiselwa emuva enjinini ngevalvu yokudlula, eletha ukuguga okungaphazamiseki kwesibili enjinini.Kusukela kulawa maphutha amabili angenhla, kungabonakala ukuthi umphumela wokuhlunga wokungcola okukhulu noma okuncane kunama-micropores wesici sokuhlunga iphepha awukwazi ukufezwa, kodwa kuphela lokho kungcola okulingana nama-micropores wesici sokuhlunga iphepha futhi kushumekwe ngaphakathi. ama-micropores wesici sokuhlunga iphepha angahlungwa.Ngakho-ke, ukusebenza kahle kokuhlunga kuphansi kakhulu.
