PVC Umbhobho jijwa umphanda for extrusion
Ubume be-Screw: Isikrufu sikholisa ukuba neshafti enemisonto kunye ne-helical groove. I-shaft ene-threaded inoxanduva lokuhambisa amandla ajikelezayo, kwaye i-helical groove inoxanduva lokukhupha kunye nokuxuba izinto zeplastiki. Uyilo lwemilo yentambo kunye ne-pitch iya kwahluka ngokweemfuno ezithile ze-extrusion.
Ukumelana nokushisa okuphezulu: Inkqubo ye-extrusion yombhobho idinga ukumelana nokushisa okuphezulu, kwaye i-screw kunye ne-barrel kufuneka ibe nokumelana nokushisa okuphezulu. Ukukhethwa kwezinto eziphezulu zensimbi ye-alloy kunye nenkqubo ekhethekileyo yonyango lokushisa kunokuphucula ukuzinza kwe-thermal ye-screw barrel.
Ikhono loxinzelelo oluphezulu: I-Extrusion idinga uxinzelelo oluphezulu ukuba lufakwe kwizinto zeplastiki, kwaye i-screw barrel kufuneka ikwazi ukumelana nolu xinzelelo oluphezulu kunye nokugcina uzinzo lwesakhiwo.
Ukumelana nokunxiba okuphezulu: Ngenxa yokunxitywa kweeplastiki kunye nezinye izongezo ngexesha le-extrusion, i-screw barrel kufuneka ibe nokuxhathisa okuphezulu. Ukusetyenziswa kwezixhobo zentsimbi ye-alloy-resistant-resistant alloy kunye neteknoloji ekhethekileyo yonyango lomphezulu kunokonyusa ukuxhathisa kwayo.
Ukutya Okufanayo: Ngexesha lokukhutshwa kombhobho, ukuyila kwe-screw barrel kufuna ukuxuba okufanayo kunye nokunyibilika kwezinto zeplastiki. Ulwakhiwo olunengqiqo lwe-screw kunye noyilo lwembaleki oluphuculweyo lunokuqinisekisa ukufana kunye nokuhambelana kwezinto.
Ukulawula ukufudumeza kunye nokupholisa: I-barrel screw idla ngokufuna ukufudumeza okuchanekileyo kunye nolawulo lokupholisa ukuqinisekisa ukuzinza kwenkqubo ye-extrusion kunye nomgangatho wemveliso. Uyilo lwenkqubo yokufudumeza kunye nokupholisa iqwalasela iimpawu zemibhobho eyahlukeneyo kunye neemfuno zenkqubo yokukhupha.
Isishwankathelo, iimpawu ze-tube screw barrel zibandakanya ukumelana nobushushu obuphezulu, ukuchasana noxinzelelo oluphezulu, ukuxhatshazwa kokugqoka, ukutya okufanayo, ukufudumeza kunye nokulawula ukupholisa, njl.
Izinto eziphathekayo: Intsimbi ye-alloy esemgangathweni ophezulu njenge-38CrMoAlA okanye i-42CrMo.
Ukuqina: Ngokuqhelekileyo malunga ne-HRC55-60.
Unyango lweNitriding: Ukuya kuthi ga kwi-0.5-0.7mm ubunzulu bokuqina komphezulu ophuculweyo kunye nokumelana nokunxiba.
I-Screw Diameter: Imiselwa bubukhulu bepaneli ethile, ububanzi, kunye neemfuno zemveliso.
I-Screw Coating: Ukuzikhethela i-bimetallic okanye i-chromium eqinileyo yokucwenga ukwenzela ukomelela okwandisiweyo.
Ukufudumeza kwe-Barel: Ukufudumeza kombane okanye ukuphoswa kweebhanti zokufudumeza i-aluminium kunye nokulawula ubushushu be-PID.
INkqubo yokuPholisa: Ukupholisa amanzi ngolawulo lobushushu ukugcina ubushushu obufanelekileyo bokusebenza.
Ulwakhiwo lweScrew: Iyilwe ngomlinganiselo ofanelekileyo wepitch kunye noxinzelelo lokukhupha okusebenzayo.
