Kuti makina otulutsira zinthu a twin-screw ayende bwino komanso bwino, yambani ndi bokosi loziziritsira ndi chakudya cham'mbali.

# ya sikuru ziwiriwolanda imagwiritsidwa ntchito kwambiri popanga ndi kukonza pulasitiki. Mu njira yeniyeni yopangira ndi kupanga, chotulutsira cha twin-screw chimagwiritsa ntchito mwayi wake wapamwamba kwambiri kuti chiwongolere kuchuluka kwa kagwiritsidwe ntchito ka zinthu zakuthupi ndikuchepetsa kuchuluka kwa zinthu zomwe zili mkati mwa chotulutsira. Kutengera kukula kosalekeza kwa kukula kwa kupanga ndi kukonza, makampani opanga ndi kukonza mapulasitiki osinthidwa apereka zofunikira zapamwamba pakugwira ntchito kwa chotulutsira cha twin-screw chokha.

Kukonzanso mabokosi oziziritsira

Kupyolera mu kuwonjezera bokosi loziziritsira mu chotulutsira cha twin-screw, kukonza ndi kukonza bwino kuchuluka kwa njira zopangira za twin-screw #pulasitiki extruder ikuchitika. Mu njira yeniyeni yopangira extrusion, chipangizo chowongolera chinyezi chimawonjezeredwa ku bokosi loziziritsira, zomwe zimachepetsa kwambiri kutayika kwa zinthu zapulasitiki kuzizira, ndipo pansi pa kuyika ma panel oteteza kutentha, mpweya wozungulira umapangidwa kuti zitsimikizire kuti zinthuzo zili bwino, ndipo mphamvu yotaya kutentha imawonekera; unyolo womwe uli m'bokosi loziziritsira umakonza njira yotumizira zinthu zapulasitiki, ndipo posintha pafupipafupi ya mota yayikulu, bokosi loziziritsira ndi chotulutsira cha twin-screw zikuyenda motsatizana; mothandizidwa ndi ndodo yothandizira, mtunda pakati pa chinthu cha pulasitiki ndi bokosi lolumikizira umachepetsedwa kuti mupewe kumamatira. Kuti mukwaniritse bwino zosowa zenizeni zopangira, kukwaniritsa cholinga chokweza mtundu wa zinthu zapulasitiki zopangira, kuonetsetsa kuti kupanga zinthu zapulasitiki kusiyanasiyana, ndikukulitsa kuchuluka kwa ntchito ndi malo a chotulutsira cha twin-screw.

Kukonza chipangizo chodyetsera m'mbali cha makina otulutsira zinthu awiri #screw

Chepetsani mpweya wosakanikirana panthawi yodyetsa

Chopondera mpweya chimayikidwa pamwamba pa doko loperekera chakudya m'mbali, screw yoyambirira imasinthidwa ndi screw ya lead, ndipo chopondera mpweya m'mbali chimagawidwa m'magawo awiri, gawo lakutsogolo limagwiritsidwa ntchito potulutsa mpweya ndipo gawo lakumbuyo limagwiritsidwa ntchito popereka chakudya. Chopondera mpweya chimathandizira kukanikiza kwa kulongedza mpweya panthawi yoperekera chakudya, ndipo chimatulutsa mpweya wosakanikirana bwino kudzera kutsogolo kwa chopondera mpweya, ndipo pamapeto pake chimatulutsa mpweya kudzera m'doko loperekera mpweya pamwamba pa doko loperekera chakudya m'mbali.

Malo omasuka asungidwa pa doko lodyetsera chakudya mbali imodzi

Mwa kuwonjezera malo omasuka a doko lodyetsera mbali imodzi, zofunikira zenizeni zodzaza zimakwaniritsidwa. Kutengera izi, chinthu chachikulu chokulungira chimapangidwa kutengera screw yomwe ilipo, chinthu chokulungira chosafanana chimayikidwa pamwamba pa doko lodyetsera mbali ya screw, chinthu chobweza chobwerera chimapangidwa mbali imodzi ya doko lodyetsera mbali ya screw, ndipo chinthu chobweza chobwerera chimapangidwa mbali inayo. Zinthu zikanyamulidwa ndi chotulutsira, zinthuzo zimalowa mu doko lalikulu lodyetsera ndikulowa mu chotulutsira. Chokulungira chimapitilira kunyamulidwa patsogolo ndipo chimatenthedwa ndikusungunuka. Zinthuzo zikafika pa chinthu chosagwirizana, zimakhala zitasungunuka. Pansi pa ntchito ya chinthu chosagwirizana, momwe zinthuzo zimagawidwira zimasintha kwambiri. Chokulungira chodyetsera mbali imodzi chimanyamulidwa mobwerera, ndipo mbali inayo imanyamulidwa mobwerera. Kutumiza mobwerera mobwerezabwereza, poyendetsa zinthu mobwerera, mbali imodzi ya doko lodyetsera imapanga dzenje pansi pa ntchito ya chinthu chobweza chobwerera, chomwe chimawonjezera kwambiri kuchuluka kwa zodzaza zomwe zimawonjezeredwa ku chipangizo chodyetsera mbali.

Dongosolo lodyetsa lapawiri

Njira yoyambirira yodyetsera kamodzi inasinthidwa kukhala njira yodyetsera nthawi imodzi yokhala ndi madoko awiri kuti ipange "njira yodyetsera kawiri". Pakusintha kwenikweni, zidapezeka kuti ma gasket omwe ali pansi pa njira yodyetsera adasunthidwa chifukwa cha kugwedezeka. Pakusintha kwachiwiri, bulaketi yokhazikika idawonjezedwa kuti ithetse bwino vuto la kugwedezeka, kukonza njira yopakira ndi maulalo, ndikukwaniritsa zolinga zosakaniza, kutulutsa, ndi kudula zida zazikulu pa kutentha kwina, ndipo mtundu wa zinthuzo pambuyo pa kupanga ndi kukonza ndi wapamwamba.
