Extruder Screw Design

Chinthu chimodzi chofunika kwambiri cha makina a screw extruder ndi screw.Mapangidwe oyenera a geometry a screw extruder ndi ofunika kwambiri pakugwira ntchito moyenera kwa extruder.

Chinthu chimodzi chofunika kwambiri cha makina ascrew extruderndi screw.Mapangidwe oyenera a geometry a screw extruder ndi yofunika kwambiri pakugwira ntchito moyenera kwa extruder.Ngati kusokonekera kwa kayendedwe kazinthu kumachitika chifukwa cha jiyomethri yolakwika, ngakhale makina apamwamba kwambiri owongolera makompyuta sangathe kuthetsa vutoli.Mapangidwe a screw nthawi zambiri amawonedwa ngati zaluso kwambiri kuposa sayansi.Zotsatira zake, malingaliro olakwika okhudza mbali zina za kapangidwe ka screw akadalipobe mpaka pano.Popeza chiphunzitso cha single wononga extrusion tsopano bwino, kamangidwe ka zomangira zomangira limodzi wononga extruder akhoza kutengera mfundo zolimba zomangamanga.Choncho, wononga kamangidwe kwa single wononga extruders sayeneranso luso, koma sayansi yokhazikika pa mfundo za umisiri polima processing.

Tsoka ilo, anthu omwe amatenga nawo mbali pakupanga zomangira sakhala anthawi zonse pa chiphunzitso cha extru-sion.Zotsatira zake, zomangira zambiri zomwe zikugwiritsidwa ntchito masiku ano zimagwira ntchito mochepera kwambiri, chifukwa cha kapangidwe kake kosayenera.Chitsanzo ndikugwiritsa ntchito kofala kwa sikonara phula.Ichi ndi phula lokhala ndi phula kosalekeza ndi phula kukhala lofanana ndi m'mimba mwake ya wononga; phulali limafanana ndi ngodya ya helix ya 17.66.Zitha kuwonetsedwa mosavuta kuti masikweya atalikirana kwambiri ndi kusungunuka ndi kusungunula kwa ma polima angapo.Izi zakhala zikudziwika kuyambira koyambirira kwa zaka za m'ma 1950, komabe zomangira zambiri za extruder zomwe zikugwiritsidwa ntchito masiku ano zimagwiritsabe ntchito mawonekedwe a square pitch.

Chomwe chingakhale chathandizira kuti zinthu zikhale bwino pakupanga zomangira ndizakuti sipanakhale mawu athunthu okhudzana ndi kapangidwe ka screw.Cholinga cha mutu uwu ndikuwonetsa momwe chiphunzitso cha extrusion chingagwiritsire ntchito kupanga bwino zomangira za extruder.Tikukhulupirira, izi zipereka maziko olimba, kutengera mfundo za injiniya, pomwe mapangidwe abwinoko komanso ogwira mtima kwambiri amatha kupangidwa mtsogolo.Mfundo za kapangidwe ka wononga sizofunikira kokha popanga zomangira zatsopano za extruder, komanso pakuwunika mavuto amtundu womwe ulipo wa extrusion.Ndikofunika kuzindikira ngati vuto likukhudzana ndi kusapanga bwino kwa screw kapena gawo lina la ndondomekoyi.Chifukwa chake, kudziwa mfundo zoyambira zopangira zomangira ndikofunikira kwa munthu aliyense wokhudzidwa ndi ma extruders.
