PVC Pipe screw barrel bakeng sa extrusion
Sebopeho sa Screw: Hangata screw e na le shaft e nang le khoele le helical groove. The threaded shaft e ikarabella ho fetisa matla a ho potoloha, 'me helical groove e ikarabella bakeng sa ho ntša le ho kopanya thepa ea polasetiki. Moralo oa sebopeho sa khoele le sekontiri se tla fapana ho ea ka litlhoko tse khethehileng tsa extrusion.
Ho hanyetsa mocheso o phahameng: Ts'ebetso ea extrusion ea pipe e hloka ho mamella mocheso o phahameng, 'me screw le barrel li tlameha ho ba le ho hanyetsa mocheso o phahameng. Khetho ea lisebelisoa tsa tšepe tsa boleng bo phahameng le mokhoa o khethehileng oa phekolo ea mocheso o ka ntlafatsa botsitso ba mocheso oa moqomo oa screw.
Bokhoni ba khatello e phahameng: Extrusion e hloka hore ho be le khatello e phahameng holim'a thepa ea polasetiki, 'me sekoti sa screw se tlameha ho khona ho mamella khatello ena e phahameng le ho boloka botsitso ba sebopeho.
Khanyetso e phahameng ea ho roala: Ka lebaka la ho roala ha polasetiki le li-additives tse ling nakong ea extrusion, moqomo oa screw o tlameha ho ba le khanyetso e phahameng ea ho apara. Tšebeliso ea lisebelisoa tsa tšepe tse sa sebetseng tsa alloy le theknoloji e khethehileng ea kalafo ea holim'a metsi e ka ntlafatsa ho hanyetsa ha eona.
Fepa Uniformity: Nakong ea extrusion pipe, moralo oa screw barrel hloka ho kopanya ho tšoanang le ho qhibiliha ha thepa ea polasetiki. Sebopeho se utloahalang sa screw le moralo o ntlafalitsoeng oa semathi se ka netefatsa ho ts'oana le botsitso ba lisebelisoa.
Taolo ea ho futhumatsa le ho pholisa: "Screw barrel" hangata e hloka taolo e nepahetseng ea ho futhumatsa le ho futhumatsa ho netefatsa botsitso ba ts'ebetso ea extrusion le boleng ba sehlahisoa. Moqapi oa mokhoa oa ho futhumatsa le o pholileng o nahanela litšobotsi tsa lisebelisoa tse fapaneng tsa liphaephe le litlhoko tsa mokhoa oa extrusion.
Ka kakaretso, litšoaneleho tsa "tube screw barrel" li kenyelletsa ho hanyetsa mocheso o phahameng, ho hanyetsa khatello e phahameng, ho hanyetsa ho apara, ho fepa ka mokhoa o ts'oanang, ho futhumatsa le ho laola ho futhumatsa, joalo-joalo Ho khetha thepa e nepahetseng le ho ntlafatsa moralo ke lintlha tsa bohlokoa ho netefatsa boleng le tlhahiso. ho sebetsa hantle ha phala extrusion.
Lintho tse bonahalang: tšepe ea boleng bo holimo e kang 38CrMoAlA kapa 42CrMo.
Ho thatafala: Ka tloaelo ho pota HRC55-60.
Kalafo ea Nitriding: Ho fihlela botebo ba 0.5-0.7mm bakeng sa ho thatafala ha holim'a metsi le ho hanyetsa ho roala.
Screw Diameter: E khethoa ke botenya bo itseng ba phanele, bophara, le litlhoko tsa tlhahiso.
Screw Coating: Ho ikhethela bimetallic kapa hard chromium plating bakeng sa ho tšoarella ho eketsehileng.
Ho futhumatsa ha Barrel: Ho futhumatsa motlakase kapa ho lahlela lihlopha tse futhumatsang tsa aluminium tse nang le taolo ea mocheso oa PID.
Cooling System: Pholiso ea metsi ka taolo ea mocheso ho boloka mocheso o nepahetseng oa ts'ebetso.
Screw Structure: E entsoe ka tekanyo e loketseng ea molumo le compression bakeng sa extrusion e sebetsang hantle.
