Eyona nto ibalulekileyo yomatshini we-screw extruder sisikrufu. Uyilo olululo lwejiyometri yesikrufu se-extruder lubaluleke kakhulu ekusebenzeni ngokufanelekileyo kwe-extruder.
Eyona nto ibalulekileyo yoomatshini aScrew extrudersisikru.Uyilo olululo lwejiyometri yesikrufu se-extruder lubaluleke kakhulu ekusebenzeni ngokufanelekileyo kwe-extruder.Ukuba ukungazinzi kothutho lwemathiriyeli kwenzeka ngenxa yejiyometri yesikrufu esingafanelekanga, kwaneyona nkqubo yolawulo yekhompyutha entsonkothileyo ayinakuyisombulula ingxaki.Uyilo lwe-Screw luhlala luthathwa njengobugcisa obuninzi kunenzululwazi.Ngenxa yoko, iingcamango eziphosakeleyo malunga nemiba ethile yoyilo lwesikrufu ziseninzi namhlanje.Kuba ithiyori ye-screw extrusion enye ngoku iphuhliswe kakuhle, uyilo lwezikrufu ze-screw extruders enye inokusekwa kwimigaqo yobunjineli eyomeleleyo.Ke ngoko, uyilo lokujija lwe-screw extruders akufuneki lube bubugcisa, kodwa isayensi esekelwe ngokuqinileyo kwimigaqo yobunjineli bokusetyenzwa kwepolymer.
Ngelishwa, abantu ababandakanyeka kuyilo lwe-screw abasoloko behlaziyiwe kwithiyori ye-extru-sion.Ngenxa yoko, izikrufu ezininzi ze-extruder ezisetyenziswayo namhlanje zisebenza kakhulu ngaphantsi kweyona ndlela iphezulu yokusebenza enokwenzeka, ngenxa yoyilo olungafanelekanga lwe-screw.Le yi-ascrew ene-pitch eqhubekayo kunye ne-pitch elingana nobubanzi be-screw; le pitch ihambelana ne-engile ye-helix ye-17.66.Ingaboniswa ngokulula ukuba i-square pitch ikude kweyona ilungileyo ngokunxulumene nokunyibilika kunye nokunyibilikisa ukuhanjiswa kwenani leepholima.Le nyani yaziwa ukusukela ekuqaleni koo-1950, kodwa uninzi lwezikrufu ze-extruder ezisetyenziswayo namhlanje zisasebenzisa uyilo lwe-square pitch eqhubekayo.
Umba onokuthi ube negalelo kwimeko yemicimbi kuyilo lwesijiva kukuba akukhange kubekho mbhalo obanzi ojongene noyilo lwesikrufu.Injongo yesi sahluko kukubonisa indlela ithiyori ye-extrusion enokusetyenziswa ngayo ukuyila ngokufanelekileyo izikrufu ze-extruder.Ngethemba, oku kuya kubonelela ngesiseko esiluqilima, esekwe kwimigaqo yobunjineli, apho uyilo olungcono nolusebenzayo lwesijiva lunokuphuhliswa kwixesha elizayo.Imigaqo yoyilo lwe-screw ayibalulekanga kuphela ekuyileni izikrufu ezitsha ze-extruder, kodwa nakuhlalutyo lweengxaki zokusetyenzwa komgca we-extrusion okhoyo.Kubalulekile ukuba ukwazi ukuqaphela ukuba ingxaki inxulumene noyilo olubi lwe-screw okanye kwenye indawo yenkqubo.Ke, ulwazi lwemigaqo esisiseko yoyilo lwe-screw lubalulekile kuye wonke umntu obandakanyekayo kwi-extruders.
