Izicelo ze-Nylon Material ku-Automobile Engine

Izingxenye ezimotweni ziwumkhakha obalulekile futhi othuthukayo wokusetshenziswa komkhiqizo wenayiloni. Inayiloni inezakhiwo ezinhle kakhulu ezihlanganisayo, kulula ukwakha kanye nokuminyana okuphansi, ngakho-ke isetshenziswe kahle ekuthuthukisweni kwesikhunta nokuhlanganisa.

Izingxenye ezingaphakathi kwendawo yenjini yemoto zidinga ukumelana nethonya lendawo eshisayo nebandayo yesikhathi eside. Indinganiso evamile ukuthi izingxenye zidinga ukumelana nezinga lokushisa lika -40 ~ 150 °C. Leli zinga lingahlangabezana nesimo sokusebenzisa sokushintshana ngokushisa nokubanda unyaka wonke; ngaphezu kwalokho, injini Izingxenye endaweni nazo zidinga ukukwazi ukumelana nomthelela we-ejenti yokuncibilika kweqhwa i-calcium chloride, i-antifreeze yesikhathi eside, amafutha ahlukahlukene nesihlabathi esindizayo.

1. Isihlungi samafutha 

Ngemva kokufaka insimbi esikhundleni se-glass fibre enayiloni eqinisiwe, ingxenye engenhla kanye nengxenye ephakathi yepayipi lensimbi ibunjwa ngo-P.A6+10% GFipulasitiki eguquliwe, kanye nemeshi yesihlungi sensimbi nengxenye ephakathi kuhlanganiswe ndawonye.

UkusebenzisaPA6+10% GFizinto eziguquliwe zokujova isihlungi samafutha zinganciphisa izinga lokuxuba komoya ngamaphuzu angu-10% -30%, izindleko zizonke zingancishiswa ngo-50%, futhi isisindo sengxenye ephelele singancishiswa ngo-70%.

2. Isembozo senjini

Ukuze kuzuzwe inhloso yokunciphisa umsindo kanye nokwenza ngcono ukunethezeka kokugibela ngesikhathi sokusebenzisa imoto, ipuleti lekhava elenziwe ngengilazi into eqinisiwe yenayiloni enomsebenzi wokuvikela umsindo isetshenziswa enjinini. Kukhona izinto zokuvikela umsindo.

Amakhava enjini adinga izinto ezisetshenziswayo: amandla aphezulu kanye nokuqina, i-warpage ephansi, ikhwalithi ebonakalayo ephezulu, uketshezi oluphezulu, kanye nokucutshungulwa kalula okusheshayo.

Ikhava yenjini

3. I-radiator

Irediyetha iyisisetshenziswa sokupholisa emotweni esehlisa izinga lokushisa lenjini lisuka ezingeni eliphezulu liye ezingeni eliphansi lokushisa. Ubakaki ophakathi nendawo, i-slot engenhla, i-slot ephansi, i-fan blade kanye nekhava yokuvikela i-blade yenziwe ngayoI-PA6+GF noma i-PA66+GFimpahla.

4. Izinto ezifakwayo nezifakwa emanzini

Ipayipi elixhumayo endaweni yokupholisa injini yesikhathi eside lingaqiniswaI-PA6+GF noma i-PA66+GF.Izifakelo zamapayipi okukhipha amanzi endaweni yokupholisa injini yesikhathi eside zinezidingo eziphakeme zokumelana nezinga lokushisa, futhi zidinga ukumelana nezinga lokushisa eliphezulu elingu-230 °C. Idinga ukukhetha izinto eziqinisa ukumelana nezinga lokushisa, njengePA46+GF.

5. Isembozo sekhanda lesilinda

Isembozo sekhanda le-cylinder singenye yezingxenye ezisetshenziswa kakhulu zezinto zenayiloni ezimotweni, okwesibili kuphela ekusetshenzisweni kokuningi.

Inhloso eyinhloko yokuhlanganisa lo mkhiqizo ukunciphisa umsindo. Lesi sici siyingxenye yokuqala ebalulekile yokunciphisa umsindo endaweni yenjini. Lo mkhiqizo usebenzisaI-PA66+GF ne-PA66+MFizinto eziguquliwe.

6. Ukudla okuhlukahlukene

I-intake manifold ikhiqizwa ikakhulukazi ngePA6+GFimpahla eguquliwe, okuyingxenye enkulu kunazo zonke zezinto zenayiloni. Manje bonke abakhiqizi bezimoto basebenzisa izinhlobo eziningi zokuthatha inayiloni.

I-manifold yokuthatha eyenziwe ngezinto zenayiloni eguquliwe inezinzuzo zesisindo esilula, izindleko eziphansi, indawo eningiliziwe ebushelelezi, umphumela omuhle kakhulu wokushisa ukushisa, ingathuthukisa ukusebenza kwenjini, inciphise umsindo, ukutshalwa kwezimali okuphansi kwemishini yokukhiqiza, futhi ibe nenzuzo ekuvikelweni kwemvelo.

Ukungenisa okuningi
