Umbhobho we-PTFEzaqala ukusetyenziswa kwicandelo leemoto kwaye zakhawuleza zaduma.Imibhobho eyenziwe kwi-polytetrafluoroethylene yenza ngcono kune-hose yerabha kwizicelo zeemoto ngenxa yokufumaneka kwayo okuphezulu kwezorhwebo kunye nokusebenza kwayo okugqwesileyo, ngoko ke ukusetyenziswa kwabo kwezorhwebo kwiimoto kuyanda.
Yintoni ithumbu le-PTFE?
Umbhobho we-PTFE yityhubhu eyenziwe yi-PTFE yangaphakathi kunye nentsimbi yangaphandle ephothiweyo njengokhuselo.Umgca we-PTFE ufana netyhubhu ye-PTFE enesigqubuthelo sokukhusela sangaphandle, ukwandisa ukunyanzeliswa koxinzelelo, njengoko kusetyenziswa iimoto kwi-PTFE hose.
Ziziphi iimpawu ze-PTFE hose?
Inert yekhemikhali, ehambelana neentlobo ezininzi zamafutha
Ukunyanzeliswa okuphantsi
I-coefficient ephantsi ye-friction
Ubunzima obulula
Ayincangathi
Non-wettingl
Ukungatsha
Imozulu / ukumelana nokuguga
Iimpawu zombane ezigqwesileyo
I-PTFE ithumbu lesibaso elinemigca - iintlobo:
Umbhobho wamafutha onyulu PTFE
Umbhobho ongundoqo wentombiPTFE umbhobho wamafuthayenziwe nge-100% ye-PTFE resin ngaphandle kwe-pigment okanye isongezo.
I-Conductive (Anti-static)PTFE umbhobho wamafutha
I-Statically dissipative okanye i-conductive ngokupheleleyo yokupheliswa kokutshatyalaliswa kweentlawulo ezimileyo ezichaphazela ukuhanjiswa kolwelo olunokutsha.Ukugijima nge-E85 kunye ne-Ethanol, okanye i-Methanol Fuel, i-PTFE eqhubayo ingundoqo yangaphakathi iyimfuneko.
Umbhobho we-PTFE wamafutha-ukhetho:
I-PTFE ephothiweyo ithumbu enomaleko we-SS enye-Oyena mbhobho wamafutha udumileyo wePTFE
I-PTFE ephothiweyo ithumbu ene-SS ephindwe kabini - Ukwandisa uxinzelelo lwezicelo ezithile
Ipayipi ephothiweyo ye-PTFE enomaleko we-SS kunye nesigqubuthelo seNayiloni emnyama-Ukukhusela okulungileyo kumaleko wentsimbi engenasici kunye nokuxhathisa kwe-abrasion
Ipayipi ephothiweyo ye-PTFE enomaleko we-SS enye kunye ne-PVC egqunywe-Ukukhusela ngokulungileyo kumaleko wentsimbi engenakutyiwa kwaye uwenze ujongeke ngakumbi kwisithuthi sakho.
Xa kuthelekiswa ne-rubber fuel hose, kutheni ukhethaPTFE umbhobho wamafutha?
Imigca yepetroli ye-PTFE yeyona ndawo ibalaseleyo endaweni yethumbu lerabha.Ngemveliso efanelekileyo kunye nezindlu, zinokuqina kakhulu kwaye zilula kakhulu ukuzifaka kwinkqubo.Nangona zingaboneleli ngoluhlu olufanayo lweelastiki olwenziwe ngerabha, imibhobho ye-PTFE imelana kakhulu nemichiza emininzi, kwaye ayisoloko ikhupha umsi, obalulekileyo kulo naluphi na uhlobo lwesithuba esivaliweyo.Oku kuxhathisa imichiza kukwathetha ukuba imibhobho ye-PTFE ibola kancinci kunemibhobho yerabha.
Ukukhuhlana komphezulu we-PTFE kukwangaphantsi kunerabha, okuthetha ukuba izinga lokuhamba lingaphuculwa ngokusebenzisa i-hose ye-PTFE.Nangona irabha ibola ngokulula kumaqondo obushushu agqithisileyo, i-PTFE iyaxhathisa kumaqondo obushushu aphezulu, iyenza ibe lolona khetho lufanelekileyo kumbhobho wamafutha kumdyarho wemoto.
Okokuqala, iUmbhobho we-PTFEisebenza njengesithintelo somphunga ukuthintela amavumba epetroli ukuba angangeni egaraji okanye evenkileni kwaye atshise xa uhambo lwakho luphumle.
Okwesibini, i-hose ene-PTFE-lined ye-hose ephezulu yokuxhathisa imichiza kwaye ixhasa iqela le-automotive fluids, engenakwenzeka ngerabha eqhelekileyo.Eyona nto ixhaphakileyo kukuba i-petroli edibeneyo iqulethe i-ethanol.Imibhobho yerabha eqhelekileyo iyabola xa idibana nale petroli, ize ekugqibeleni ibole de iqalise ukuvuza okanye ukutofa isibaso-nto leyo eyingozi kakhulu.
Okwesithathu, i-hose ye-PTFE ene-hose inokumelana nobushushu obuphezulu kakhulu-enyanisweni, uluhlu lweqondo lokushisa lokusebenza lombhobho othengiswa ngumbhobho wethu wamafutha ngu -60 degrees Celsius ukuya +200 degrees Celsius.Kufanelekile kakhulu ukuvula umbhobho wamanzi kwimoto yakho yezemidlalo.
Okwesine, i-hose yethu ye-PTFE yamafutha inoxinzelelo oluphezulu kakhulu lokusebenza, kwakhona iqinisekisa ukuba ungayisebenzisa kuzo zonke iintlobo zezicelo zeemoto.Ubungakanani be-AN6 bufanelekile kwi-2500PSI, ubukhulu be-AN8 bufanelekile kwi-2000psi-nokuba izicelo ezifunwa kakhulu, kukho uxinzelelo olwaneleyo.
Ngowuphi umgca wamafutha owudingayo ukuze usebenze nge-E85 kunye ne-ethanol, okanye i-methanol fuel?
Ukusetyenziswa kwe-ethanol kunye namafutha e-methanol kuye kwathandeka ngakumbi nangakumbi kwiminyaka yakutshanje, ngakumbi ngokunyuka kweenjini eziphezulu ze-turbocharged supercharged.I-E85 okanye i-ethanol ibonakalise ukuba yi-fuel eneendleko ezinokubonelela ngezicelo ezifunwayo kunye nokulinganisa kwe-octane kunye namandla anamandla.Ukongezelela, kunokuvelisa umphumo wokupholisa emoyeni wokungenisa.
Nangona kunjalo, i-ethanol i-corrosive, kwezinye iimeko iya kwenza i-gel-efana ne-gel, kwaye inokonakalisa amacandelo e-fuel system, ngaphandle koko ayiyi kuchaphazeleka ngepetroli kunye ne-racing gas.
Kufuneka kusetyenziswe isihluzo esikhethekileyo samafutha.Ngokuqinisekileyo kufuneka uqinisekise ukuba impompo yakho yamafutha iyahambelana, kodwa kuthekani ngomgca wamafutha?
Umbhobho we-PTFE unokubonelelwa nge-braid yensimbi engenasici kunye neengubo ezimnyama.Esi simbo sokuqhuba i-PTFE isebenzisa i-braid yangaphandle kunye ne-PTFE liner yangaphakathi, exhathisa kakhulu kwizinto zekhemikhali kunye nokubola kwe-thermal.I-Conductive wire ibalulekile ukuba isetyenziswe kwaye ithathele ingqalelo ukuba ukhetha i-PTFE, kuba intlawulo ye-electrostatic eveliswa yi-fuel flow ngokwenene iya kutshisa / itshise kwaye ibangele intlawulo, eya kubangela umlilo.
I-PTFE inzima kakhulu ukuhlanganisa, kodwa ubomi bayo abuchatshazelwa lula bubushushu kunye noxinzelelo.Oku kuyenza ibe lukhetho olugqwesileyo kumafutha adlekayo, kunye nemigca yokulawula amandla, imigca yeoli ye turbine, njl. Ngenxa yezi zizathu, ikwalukhetho olulungileyo lwe-E85 kunye namafutha e-ethanol kunye ne-methanol.
