Kodi Parallel Twin Screw Barrel Ndi Chiyani Ndipo Imagwira Ntchito Motani?

Funsani ogulitsa atatu kuti mbiya yamapasa yofananira ndi chiyani ndipo mupeza mayankho atatu osamveka bwino okhudza "zomangira ziwiri m'malo mwa chimodzi." Izo zimatsitsa izo. Mapangidwe a mapasa amasintha momwe zinthu zimayendera pamakina, ndipo kusiyana komwe kumapangidwira ndiko chifukwa chake zomangira zimagwira ntchito zomwe sikona imodzi siyingathe.

Bukuli limakhudza zimango, ma nkhwangwa awiri omwe amasankha momwe angagwiritsire ntchito, zinthu zenizeni, komanso kukula kwake. Kuti muwone zambiri zachigawocho, onani wathuextruder screw mbiya kalozera.

Kodi Parallel Twin Screw Barrel Ndi Chiyani?

Kufanana twin screw barrel ndi plasticizing unit ya twin screw extruder. Ili ndi magawo awiri omwe amagwira ntchito ngati dongosolo limodzi: mbiya yokhala ndi zibowo ziwiri zopindika, zomwe zimapanga gawo la mtanda lachisanu ndi chitatu, ndi zomangira ziwiri zomwe zimakhala mkati mwake.

Kufananazikutanthauza kuti zomangira zimasunga m'mimba mwake momwemo kuyambira kumapeto kwa chakudya mpaka kumapeto. Bore limakhala lofanana kukula kwake lonse. Kumeneku ndiko kusiyana kwakukulu kuchokera ku mapasa a conical, pomwe zomangira zonse ndi zomangira zimatsikira ku kufa.

Mawonekedwe ofananawo amapatsa wokonzayo gawo lokhazikika la mtanda kuti azigwira ntchito limodzi ndi kutalika kwake konse, zomwe zimapangitsa kukhala kosavuta kupanga makina aatali okhala ndi malo ophatikizira, kutulutsa mpweya, ndi kusakaniza magawo. Kufananiza pakati pa mafomu awiriwa kukuphimbidwa m'nkhani yathuconical vs parallel guide.

Momwe Parallel Twin Screw Barrel Imagwirira Ntchito, Gawo ndi Gawo

1. Kudyetsa.Zinthu zimagwera pakhosi ndikugwera pa zomangira zonse ziwiri nthawi imodzi. Zomangira ziwiri zimatenga ufa, ma flakes, ndi chakudya chosakhazikika chomwe sikona imodzi imavutikira kugwira.
2. Kutumiza.Zomangira zimatembenuka ndipo kuwuluka kwa screw imodzi kumapukuta njira ya inayo. Zofunika zimatsekeredwa mu zipinda zooneka ngati C pakati pa maulendo apaulendo ndi kukankhidwira kutsogolo ndi makina.
3. Kusungunuka.Zotenthetsera za migolo zimapereka gawo la kutentha. Zina zimachokera ku kumeta ubweya pamene zinthuzo zimagwiritsidwa ntchito mumpata wopapatiza pomwe zomangira zimalumikizana, yomwe ndi gawo lolimba kwambiri pamakina.
4. Kusakaniza.Kuzungulira kulikonse kumagawaniza, kupindika, ndikuphatikizanso mtsinje wosungunuka. Kugawanika kobwerezabwereza ndiko komwe kumabalalitsa zodzaza, ma pigment, ndi zowonjezera mofanana.
5. Kutulutsa mpweya.Pa mbiya yotuluka mpweya, tchanelo chimazama padoko lolowera mpweya kotero kuti kupanikizika kumatsika mpaka kufupi ndi ziro. Chinyezi ndi zowomba zimathawira kumeneko, nthawi zambiri popanda vacuum.
6. Kupopa ndi metering.Gawo lomaliza limapanga kukakamiza ndikupereka kusungunuka kokhazikika kukufa kapena pelletizer.

Co-Rotating vs Counter-Rotating: Njira ziwiri, Ntchito ziwiri

Zomangira zimatha kutembenukira mbali imodzi kapena mbali zina. Chisankho chimodzi chimenecho chimasintha mawonekedwe a makina kwathunthu.

Kuzungulira kozungulirazomangira ndi chida chophatikizira. Kumeta ubweya wambiri komanso kuthamanga kwambiri kumabalalitsa ulusi wagalasi, pigment, ndi zowonjezera bwino, zomwe ndizomwe zimafunikira gulu losinthidwa.

Potsutsa-kuzungulirazomangira zimagwira ntchito ngati mpope wosuntha wabwino. Mphuno pakati pawo imanyamula zinthu kutsogolo pansi pa kukameta ubweya wochepa, ndipo ndizomwe zimafuna PVC yolimba, popeza PVC imawononga mukameta mwamphamvu. Zathumigolo yozungulira yozungulira yofanana ndi mapasazimapangidwira ntchitoyo, ndipo chemistry kumbuyo kwake imakhala mwathuPVC screw barrel guide.

Mwathunthu, Mwapang'ono, Kapena Osakhala ndi Meshing: Ma Axis Ambiri Amadumphira

Njira yozungulira ndi theka la magawo. Mzere wachiwiri ndi momwe zomangira ziwirizi zimalumikizirana, ndipo maupangiri ambiri samatchulapo.

Zomangira zathu zamapasa zofananira zimabwera m'mitundu itatu ya meshing:mameshing kwathunthu, ma meshing pang'ono, komanso osalumikizana. Kusiyana kwake ndikuti kuwuluka kwa screw imodzi kumafikira panjira ya inzake.

• Kwathunthu meshing.Kuwuluka kwa wononga imodzi kumafika muzu wa winayo, ndikusiya kusiyana kochepa. Uwu ndiye mtundu wodziwika kwambiri mu mapulasitiki otulutsa, chifukwa chilolezo cholimba chimapereka kumeta bwino komanso kusakanikirana ndikupukuta mayendedwe pomwe zomangira zimatembenuka.
• Pang'ono meshing.Zomangira zimalumikizana, koma mozama. Kutumiza kumakhalabe kwabwino pomwe kukameta ubweya kumatsika, komwe kumagwirizana ndi zinthu zomwe sizingagwire ntchito mwaukali.
• Zopanda meshing.Zomangira zimakhala mbali ndi mbali popanda kuchitapo kanthu. Makinawa amakhala pafupi ndi zomangira ziwiri zimodzi mumbiya imodzi, zokhala ndi chithandizo chofewa kwambiri komanso zosawoneka bwino.

Chomwe chimapangitsa kuti "twin screw" chokhacho chisafotokoze makina. Kulumikizana kwathunthu ndi kusinthasintha ndi chida chosiyana ndi ma meshing ndi kuzungulira kwathunthu, ndipo zonsezi zimasiyana ndi dongosolo lopanda ma meshing. Mukatchulanso seti yowonjezera, mtundu wa meshing uyenera kufanana ndi makina omwe muli nawo.

Chifukwa Chimene Ma Twin Screws Amatulutsa Mosiyana ndi Zingwe Zokha

Sikwala limodzi ndi pampu yokoka. Zimadalira kugundana: zakuthupi ziyenera kumamatira ku khoma la migolo kuposa momwe zimamatirira pa screw, kapena zimangozungulira m'malo mopita patsogolo.

Kudalira kumeneko kumabweretsa mavuto enieni. Ufa, ma flakes, ndi chakudya choterera kapena chotsitsa pang'ono sizigwira bwino, chifukwa chake wononga kapena kufa ndi njala. Zotsatira zake zimasiyanasiyana ndi momwe zinthu zimagwirira ntchito tsiku limenelo.

Zomangira ziwiri zimapereka zabwino. Kuwuluka kwa screw imodzi kumasesa njira ya inzake, motero zinthu zimakankhidwa mwamakina kaya zikugwira khoma kapena ayi. Zotulutsa zimakhalabe zokhazikika, ndipo chakudya chomwe chimagonjetsera screw imodzi chimadutsa popanda kudandaula.

Ichi ndichifukwa chake zomangira ziwiri zimalamulira kuphatikiza ndi ntchito ya ufa wa PVC. Kuyerekezera kwathunthu kuli m'miyoyo yathusingle screw vs twin screw guide.

Zomangira zopanda ma meshing zimakhala mbali ndi mbali popanda kuchitapo kanthu, kumapereka chithandizo chaulemu kwambiri.

Kodi pali kusiyana kotani pakati pa parallel ndi conical twin screws?

Zomangira zofananira zimasunga m'mimba mwake momwemo kuchokera ku chakudya mpaka kukhetsa, ndipo borelo limakhalabe kukula kosalekeza. Zomata zapawiri zopindika, zokhala ndi malekezero okulirapo omwe amafikira kufa. Fomu yofananira imapereka gawo lokhazikika pamtanda motalika, zomwe zimapanga makina aatali okhala ndi mpweya ndi kusakaniza magawo molunjika kuti amange.

Nchifukwa chiyani mugwiritsire ntchito zomangira ziwiri m'malo mogwiritsa ntchito screw imodzi?

Kulankhula kwabwino. Chomangira chimodzi chimadalira kugundana, chifukwa chake zinthu ziyenera kugwira khoma la migoloyo kuti zipite patsogolo, ndipo ufa, ma flakes, ndi chakudya choterera zimayambitsa kuphulika. Zomangira ziwiri zimakankhira zinthu motsatira makina mosasamala kanthu za kugwira, zomwe zimapangitsa kuti ziwonjezeke komanso kuwalola kuti azigwira chakudya chomwe chimagonjetsera screw imodzi.

Kodi zomangira zamapasa zimagwiritsidwa ntchito chiyani?

Mabanja anayi akuluakulu: kusinthidwa kwa pulasitiki ndikuphatikiza ndi ulusi wagalasi, ulusi wa kaboni, kapena zoletsa moto; mtundu ndi zinchito masterbatch kupanga; extrusion wa chitoliro, mbiri, pepala, ndi filimu kuphatikizapo PVC ndi PC; ndi kukonza pulasitiki zobwezerezedwanso kumene zinyalala PP ndi PE amatsukidwa, kukonzanso pulasitiki, ndi pelletized.

Kodi zomangira ziwiri zikuyenera kusinthidwa ngati ma peyala?

Inde. Chilolezo cha intermesh pakati pa zomangira ziwirizo chimayikidwa popanga ndipo sichingabwezedwe posintha skruru imodzi motsutsana ndi mnzake wotopa. Zomangira zamapasa zimapangidwa, kuperekedwa, ndikusinthidwa ngati zofananira, ndipo ziyenera kusungidwa ndikusamalidwa motere.
