Thaum muas lub extruder, peb yuav tsum ua tib zoo tshuaj xyuas peb cov kev xav tau tiag tiag. Nyob rau tib lub sijhawm, kev nkag siab zoo ntawm tus neeg xa khoom thiab cov extruders lawv muab kuj tseem ceeb heev. Feem ntau, ua ntej txiav txim siab yuav ib qho extruder tshiab, tuam txhab uas muag twb muaj kev nkag siab dav dav ntawm seb lawv xav tau ntxaib - ntsia hlau lossis ib leeg - ntsia hlau extruder thiab cov khoom siv dab tsi uas lawv xav tau los tsim. Tom ntej no, raws li qhov tshwj xeeb ntawm cov khoom, xa mus rau cov ntawv xov xwm ntawm "screw txoj kab uas hla thiab qhov ntev ntawm cov khoom," cov ntsia hlau txoj kab uas hla tuaj yeem xaiv thawj zaug. Thaum kawg, qhov tshwj xeeb tshwj xeeb thiab cov qauv ntawm extruder yog txiav txim siab ntxiv raws li cov ntsia hlau taub.
Tom qab txiav txim siab txog hom thiab cov kev qhia tshwj xeeb ntawm extruder, xaiv cov chaw tsim khoom tsim khoom yuav yog qhov teeb meem tseem ceeb. Muaj ntau lub tuam txhab extruder hauv tsev nrog cov keeb kwm ntev, muaj peev xwm muaj zog, thiab kev ua haujlwm nplua nuj; lawv cov khoom zoo thiab tom qab - kev muag khoom yog tsim nyog xav txog.
Tom ntej no, peb yuav tham txog qhov ceev ceev. Screw ceev yog ib qho tseem ceeb cuam tshuam rau lub peev xwm extruder. Nws tsis tsuas yog txiav txim siab extrusion ceev thiab kom muaj nuj nqis ntawm cov khoom tab sis kuj muaj kev cuam tshuam loj heev rau cov nyhuv plasticizing. Yav dhau los, txoj hauv kev tseem ceeb los ua kom cov khoom tso tawm extruder yog ua kom cov ntsia hlau taub. Txawm li cas los xij, tsuas yog nce lub hau ntswj txoj kab uas hla, thaum nce tus nqi ntawm cov khoom extruded ib lub sij hawm, tsis lav zoo plasticizing teebmeem. Qhov no yog vim hais tias cov ntsia hlau, ntxiv rau extruding cov khoom, kuj yuav tsum tau compress, agitate, thiab shear cov yas. Nrog rau qhov ceev ceev tas li, lub taub hau loj dua nrog cov ntsia hlau loj dua feem ntau muaj kev ntxhov siab tsawg dua thiab kev sib tsoo ntawm cov khoom piv rau lub taub me me.
Yog li ntawd, niaj hnub extruders nyiam ua kom muaj peev xwm los ntawm kev ua kom ceev ceev. Cov tsoos extruder ntsia hlau ceev yog feem ntau 60 mus rau 90 rpm, thaum cov cuab yeej siv niaj hnub tau nce mus rau 100 txog 120 rpm, lossis ntau dua. Tau kawg, kev nce cov ntsia hlau nrawm yuav ua rau kom lub zog ntawm lub hau ntswj, tab sis los ntawm kev txhim kho cov khoom siv ntsia hlau, txhim kho cov txheej txheem ntau lawm, thiab tsim kev tsim cov qauv ntawm cov ntsia hlau, torque tuaj yeem txo tau zoo thiab cov ntsia hlau load- cov kabmob muaj peev xwm txhim kho.
Tsis tas li ntawd, qhov cuam tshuam ntawm cov qauv ntsia hlau ntawm lub peev xwm extruder tsis tuaj yeem tsis quav ntsej. Ib qhov zoo-tsim ntsia hlau tuaj yeem ua tau zoo heev plasticizing teebmeem ntawm kev kub ceev, yog li ua kom muaj peev xwm. Lub caij no, kev txhim kho rau cov qauv ntawm lub thoob kuj tseem ceeb heev, feem ntau suav nrog kev tswj xyuas qhov kub thiab txias hauv seem pub thiab kev tsim cov khoom noj kom zoo los xyuas kom meej cov khoom zoo nkag mus rau hauv cov ntsia hlau thiab cov yas kom zoo.
Kev tswj kom zoo ntawm lub tsho dej kub yog qhov tseem ceeb rau kev ua haujlwm ruaj khov extruder thiab zoo extrusion. Yog hais tias lub tsho dej kub siab dhau lawm, cov khoom siv raw yuav soften ntxov ntxov, txawm tias melting ntawm cov particle deg, txo kev sib txhuam ntawm cov khoom thiab lub chim phab ntsa, yog li cuam tshuam extrusion thrust thiab tso zis. Conversely, tsis tshua muaj kub ua rau cov ntsia hlau tig tsis kam, muaj peev xwm tshaj lub cev muaj peev xwm, ua rau pib nyuaj los yog tsis ruaj tsis khov ceev. Advanced sensors thiab tswj technology tso cai rau tiag tiag - lub sij hawm saib xyuas thiab meej tswj ntawm lub extruder lub tsho dej, kom ntseeg tau tias nws kub nyob rau hauv lub optimum txheej txheem parameter ntau yam.
Kev xaiv ntawm qhov ceev reducer kuj tseem ceeb heev hauv kev tsim extruder. Tus nqi tsim khoom ntawm qhov ceev reducer yog ncaj qha proportional rau nws qhov loj thiab qhov hnyav, vim tias qhov loj dua qhov reducer xav tau cov khoom siv ntau dua thiab cov kabmob loj dua. Tsis tas li ntawd, siab -ceev, siab- extruders ua tau zoo yuav tsum muaj lub cev muaj zog ntau dua thiab cov ncej loj dua qhov nrawm dua piv rau cov pa extruders. Txawm li cas los xij, cov ntsia hlau siab ceev txhais tau tias qhov txo qis qis, uas ua rau muaj kev nce hauv iav module, yog li ua rau cov khoom thauj - bearing peev xwm ntawm reducer. Yog li ntawd, txawm hais tias qhov hnyav ntawm tus reducer nyob rau hauv siab -ceev, siab - extruder efficiency yuav nce, nws cov nqi tsim khoom ib chav tsev tso zis tseem qis dua li cov pa extruder.
