Ukwethulwa kwamapayipi e-Intercooler kuma-Turbocharger? | I-PASSIONHOSE

Isingeniso se-turbocharger

Uhlelo lokungenisa umoya kanye nokukhipha umoya lwenjini yemoto olune-turbocharger ngokuvamile lwakhiwe izihlungi zomoya, ama-turbocharger, ama-intercooler kanye namapayipi okuxhuma nezinye izingxenye.

Ipayipi lokuhambisa umoya kumele lixhunywe ngepayipi lerabha kanye nepayipi lensimbi noma ipayipi lerabha kanye nepayipi lokuphefumula noma ipayipi lokuphefumula eliqondile. Ngosizo lokuguquguquka okuhle kanye nokudlidliza kwepayipi lokuphefumula lerabha noma elihlanganisiwe, ukwakheka kwepayipi kanye nokuhlanganiswa kwalo kungenziwa lula, futhi ikhono lohlelo lwepayipi lokuhambisa umoya lokuvimba ukudlidliza lingathuthukiswa kakhulu.

Ngemva kokuba umoya omusha usuhlungiwe ngesihlungi somoya futhi ucindezelwe yi-turbocharger, igesi ephakathi izokhuphuka kakhulu ngokucindezelwa futhi izinga lokushisa ngokuvamile lizofinyelela phakathi kuka-150°C no-200°C. Kodwa-ke, ezinjinini ezinezilinganiso eziphezulu zokuphakamisa, izinga lokushisa legesi lingadlula u-200°C noma lifinyelele ngisho no-275°C noma ngaphezulu.

Igesi ipholiswa yi-intercooler bese yehliswa ibe ngaphansi kuka-60 ℃, ngaleyo ndlela kwandisa ubuningi bomoya omusha, ukuze injini ikwazi ukumunca umoya omningi, futhi ikwazi ukufutha uphethiloli omningi, ukukhuthaza ukusha okugcwele, ukunciphisa ukusetshenziswa kukaphethiloli kanye nokukhishwa komoya, ukuthuthukisa izinhloso zamandla enjini.

Umklamo wepayipi le-Intercooler kanye nemibono yokukhetha izinto

1, izinga lokushisa lokusebenzisa ipayipi lokungenisa umoya eliphakathi nendawo elifinyelela ku-150 ℃ ~ 275 ℃, izinto kumele zihlangabezane nokushisa okuphezulu nokuphansi okuhle, ukumelana okuhle kwamafutha kanye nokumelana nesimo sezulu. Phakathi kwezinhlobo zerabha ezisetshenziswa kabanzi, ezivamile irabha yemvelo, irabha ye-styrene-butadiene, irabha ye-nitrile, irabha ye-EPDM, irabha ye-chlorobutyl, irabha ye-silicone, irabha ye-acrylate, irabha ye-fluorosilicone kanye nerabha ye-fluorine.

2, irabha ye-EPDM, irabha ye-butyl e-chlorinated ifaneleka kakhulu ukusetshenziswa kwesikhathi eside ku-120 ℃, ukusetshenziswa kwesikhathi esifushane ku-150 ℃ ngaphansi kwezimo zobuchwepheshe bokuguga obumelana nokushisa, kusobala ukuthi ayivumelani nepayipi lokungenisa umoya eliphakathi kokupholisa. Futhi irabha ye-silicone, irabha ye-acrylate, irabha ye-fluorosilicone, irabha ye-fluorine, ukumelana nokushisa okuphezulu sekufinyelele ku-150 ℃ nangaphezulu, okungasetshenziswa njengepayipi lokungenisa umoya eliphakathi kokupholisa.

3, ku-silicone raber, i-acrylate raber, i-fluorosilicone raber, i-fluorine raber nezinye izinto ezinokumelana okuhle kakhulu nokushisa okuphezulu, okuwukuphela kwezinto azinawo ukumelana okuhle kwamafutha kwe-silicone raber, kodwa i-silicone raber iyona eshibhile kakhulu kulezi zinto ezine, lapho i-acrylate raber, i-fluorosilicone raber, intengo ye-fluorine raber icishe ibe yi-silicone izikhathi ezi-2, izikhathi eziyi-17, izikhathi eziyi-6. Ngakho-ke esakhiweni esivaliwe, uhlelo lokuhlukanisa uwoyela negesi ku-intercooler intake hose ezintweni zenjoloba uma ukhetha i-fluorosilicone raber, i-fluorine raber, ayinazo izinzuzo zezindleko, kodwa i-acrylate raber ukumelana nokushisa okuphezulu okungu-175 ℃ kuphela, ingasetshenziswa njengevolumu encane yokukhipha injini.

4, thatha ukuguqulwa kwezinto ze-polymer kanye nomklamo ohlukile ohlelekile kuyindlela ephumelela kakhulu. I-silicone eshisayo kakhulu futhi engabizi kakhulu kanye nokumelana okuhle kakhulu kwamafutha enjoloba ye-fluorosilicone, injoloba ye-fluorine yokuguqulwa kokuxuba, okungukuthi, ipayipi elimbozwe ungqimba lwenjoloba olungamelana namafutha, ezinye izingxenye zesakhiwo se-silicone "i-fluorine ngaphandle kwe-silicon", ukuhlangabezana nezidingo zenjini, ngenkathi kunciphisa izindleko zenhloso.

I-polymer ye-Fluorosilicone (i-FVMQ noma i-FPM/VMQ noma i-resin ye-fluorine exutshwe ne-silicone, njll.) ayinayo kuphela ukusebenza okuhle kakhulu kokumelana okuphezulu nokuphansi kanye nokusebenza okuphelele kwerabha ye-silicone (VMQ), kodwa futhi nokumelana okungcono kwamafutha kwerabha ye-acrylate (AEM). Ixazulula inkinga yokumelana okungekuhle kwamafutha kwamapayipi e-silicone endabuko kanye nokumelana okungekuhle namazinga okushisa aphezulu naphansi kwamapayipi e-AEM ne-ACM futhi ihlangabezana nesakhiwo esisha semikhiqizo ye-polymer enezimo ezinzima nezinzima zokusebenzisa amapayipi okuxhuma umoya ophumayo kanye nowokungenisa umoya ezimotweni.
