1. Isantya sokukrazula
Ngaphambili, indlela ephambili yokunyusa imveliso ye-extruder yayikwandisa ububanzi be-screw.Nangona ukwanda kwe-screw diameter kuya kwandisa inani lezinto ezikhutshiweyo ngexesha leyunithi.Kodwa i-extruder ayisiyonto yokuhambisa isikrufu.Ukongeza kokukhupha izinto, isikrufu sikwakhupha, sixube kwaye sichebe iplastiki ukuze siyifake iplastiki.Ngaphantsi kwesiseko sesantya esiqhubekayo se-screw, ukuxuba kunye nefuthe lokucheba le-screw kunye ne-diameter enkulu kunye ne-screw groove enkulu kwizinto eziphathekayo ayilungile njenge-screw ene-diameter encinci.Ke ngoko, ii-extruders zanamhlanje zonyusa umthamo ngokunyusa isantya se-screw.Isantya screw of extruder eqhelekileyo 60 ukuba 90 rpm for extruders zemveli.Kwaye ngoku yonyuswe ngokubanzi ukuya kwi-100 ukuya kwi-120 rpm.Isantya esiphezulu se-extruders sifikelela kwi-150 ukuya kwi-180 rpm.
2. Ulwakhiwo lwezikrufu
Isakhiwo se-screw yinto ephambili echaphazela umthamo we-extruder.Ngaphandle kolwakhiwo olufanelekileyo lwe-screw, ukuzama ukwandisa ngokulula isantya se-screw ukunyusa umthamo we-extrusion kuchasene nomthetho wenjongo kwaye akuyi kuphumelela.Uyilo lwesantya esiphezulu kunye nokusebenza okuphezulu kwe-screw kusekelwe kwisantya esiphezulu sokujikeleza.Impembelelo yeplastiki yolu hlobo lwe-screw iya kuba yimbi ngesantya esiphantsi, kodwa i-plasticizing effect iya kuphucula ngokuthe ngcembe xa isantya se-screw sandiswa, kwaye umphumo ongcono kakhulu uya kufumaneka xa isantya sokuyila sifikelelwe.Ngeli xesha, zombini umthamo ophezulu kunye neziphumo ezifanelekileyo zeplastiki ziyafezekiswa.
3. Ibhokisi yegiya
Iindleko zokwenziwa kwesixhobo sokunciphisa zilingana ngokulinganayo nobukhulu bayo kunye nobunzima, ngaphandle kokuba isakhiwo siyafana.Ubungakanani obukhulu kunye nobunzima bebhokisi yegiya kuthetha ukuba izinto ezininzi ziyasetyenziswa kwinkqubo yokwenziwa kwaye iibheringi ezisetyenzisiweyo zinkulu, nto leyo eyandisa iindleko zokwenziwa.Ngokubhekiselele kwimveliso yeyunithi, amandla asezantsi emoto kunye nobunzima obuphantsi bebhokisi yegiya yesantya esiphezulu esisebenza ngokugqibeleleyo sithetha ukuba iindleko zokwenziwa kweyunithi nganye yokuphuma kwesantya esiphezulu esisebenza ngokufanelekileyo sisezantsi kuneso se-extruder eqhelekileyo.
4. Ukuqhuba imoto
Kwi-extruder ye-screw diameter efanayo, isantya esiphezulu kunye nokusebenza okuphezulu kwe-extruder kudla amandla amaninzi kune-extruder yesiqhelo, ngoko kuyimfuneko ukunyusa amandla emoto.Ngethuba lokusetyenziswa okuqhelekileyo kwe-extruder, inkqubo ye-motor drive kunye nenkqubo yokufudumeza kunye nokupholisa ihlala isebenza.I-screw diameter efanayo ye-extruder ene-motor enkulu ibonakala ilambile amandla, kodwa ukuba ibalwe ngemveliso, isantya esiphezulu kunye ne-extruder esebenzayo ephezulu inamandla ngakumbi kune-extruder yesiqhelo.
5. Amanyathelo okudambisa ukungcangcazela
I-high-speed extruders ixhomekeke kwi-vibration, kwaye ukungcangcazela okugqithisileyo kuyingozi kakhulu kusetyenziso oluqhelekileyo lwezixhobo kunye nobomi benkonzo yamacandelo.Ngoko ke, amanyathelo amaninzi kufuneka athathwe ukunciphisa i-vibration ye-extruder ukwenzela ukwandisa ubomi benkonzo yezixhobo.
6. Izixhobo
Ukusebenza kwemveliso ye-extrusion ngokusisiseko yibhokisi elimnyama, kwaye imeko yangaphakathi ayinakubonwa nonke, kwaye inokubonakaliswa kuphela ngokusebenzisa izixhobo.Ngoko ke, i-instrumentation echanekileyo, ehlakaniphile kwaye kulula ukuyisebenzisa iya kusenza siqonde ngcono imeko yayo yangaphakathi, ukwenzela ukuba imveliso ikwazi ukufikelela ngokukhawuleza kunye neziphumo ezingcono.
