Isici somshini esibaluleke kakhulu se-screw extruder isikulufu.Idizayini efanele yejiyomethri yesikulufu se-extruder ibaluleke kakhulu ekusebenzeni kahle kwe-extruder.
Into eyodwa ebaluleke kakhulu yemishini ye-aisikulufa extruderyisikulufu.Idizayini efanele yejiyomethri yesikulufu se-extruder ibaluleke kakhulu ekusebenzeni kahle kwe-extruder.Uma ukuntengantenga kwezinto zokuthutha kwenzeka ngenxa ye-screw geometry engafanele, ngisho nesistimu yokulawula yekhompyutha eyinkimbinkimbi kakhulu ayikwazi ukuxazulula inkinga.I-Screw design isabhekwa njengobuciko obuningi kunesayensi.Ngenxa yalokho, imibono eyiphutha mayelana nezici ezithile ze-screw design isagcwele nanamuhla.Njengoba itiyori ye-screw extrusion eyodwa manje isithuthukiswe kahle, ukuklanywa kwezikulufu ze-screw extruder eyodwa kungase kusekelwe ezimisweni zobunjiniyela eziqinile.Ngakho-ke, idizayini yesikulufu ye-screw extruder eyodwa akufanele kusaba ubuciko, kodwa isayensi esekelwe ngokuqinile ezimisweni zobunjiniyela bokucubungula i-polymer.
Ngeshwa, abantu abathintekayo ekwakhiweni kwesikulufa abahlali besesikhathini samanje ngethiyori ye-extru-sion.Ngenxa yalokho, izikulufu eziningi ze-extruder ezisetshenziswayo namuhla zenza ukusebenza okungaphansi kobukhulu obungenzeka, ngenxa nje yedizayini yesikulufu esingafanele.Isibonelo ukusetshenziswa okusejwayelekile kwesikulufu se-square pitch extruder.Lokhu kuyi-ascrew ene-pitch engaguquki lapho iphimbo lilingana nobubanzi besikulufu; le nkinobho ihambisana ne-engeli ye-helix engu-17.66.Kungaboniswa kalula ukuthi i-pitch yesikwele ikude kakhulu nokuhle ngokuphathelene nokuncibilika nokuncibilika kokudlulisa kwenani lamapholima.Leli qiniso laziwa kusukela ekuqaleni kwawo-1950, nokho izikulufu eziningi ze-extruder ezisetshenziswa namuhla zisasebenzisa idizayini yephimbo yesikwele engashintshi.
Isici esingahle sibe nomthelela esimweni sezindaba ekwakhiweni kwesikulufu ukuthi akukaze kube khona umbhalo ophelele osebenza ngokuklama isikulufu.Inhloso yalesi sahluko ukukhombisa ukuthi ithiyori ye-extrusion ingasetshenziswa kanjani ukuklama kahle izikulufu ze-extruder.Ngethemba, lokhu kuzohlinzeka ngesisekelo esiqinile, esisekelwe ezimisweni zobunjiniyela, lapho imiklamo yezikulufo engcono nesebenza kangcono ingathuthukiswa ngokuzayo.Izimiso zokudizayina ngezikulufu azibalulekile nje kuphela ekwakhiweni kwezikulufi ezintsha ze-extruder, kodwa futhi nasekuhlaziyeni izinkinga zokucubungula zomugqa osuvele ukhona we-extrusion.Kubalulekile ukwazi ukubona ukuthi ingabe inkinga ihlobene nokuklanywa kwesikulufa esingesihle noma kwenye ingxenye yenqubo.Ngakho-ke, ulwazi lwezimiso eziyisisekelo zokuklama isikulufa lubalulekile kuwo wonke umuntu ohilelekile kuma-extruder.
