A parallel twin screw barrelinobata masiruuru maviri anogara ari dhayamita padivi nepadivi mumufananidzo-sere bore. Iyo screws inotenderera pamwe chete uye inosundira zvinhu kumberi nekuiteya pakati pendege, pane kuidhonzera nemadziro sezvinoita screw imwe chete. Sarudzo mbiri dzekugadzira dzinosarudza zvingaitwe nemuchina: iyo yekutenderera (kutenderera-kutenderera kana kupotera-kutenderedza) uye kuti zvakadzika sei maseruru mesh (zvakazara, chikamu, kana kwete zvachose). Tora iwo maviri ekurudyi uye akafanana Hardware makomisheni, mamhepo, kana extrudes yakaoma PVC.
Bvunza vatengesi vatatu kuti parallel twin screw barrel chii uye unowana mhinduro nhatu dzisina kujeka nezve "ma screws maviri pachinzvimbo cheimwe." Izvozvo zvinozvideredza. Kurongeka kwemapatya kunoshandura mafambiro anoita zvinhu nemuchina, uye musiyano iwoyo wemuchina ndosaka mapatya masiruru achibata mabasa siruu imwe chete isingagone.
Iri gwara rinovhara makanika, iwo maviri echikamu mbezo anosarudza kuita, iwo chaiwo ezvinyorwa specs, uye saizi. Kuti uwane iyo yakafara chikamu mufananidzo, ona yeduextruder screw barrel guide.
Chii chinonzi Parallel Twin Screw Barrel?
A parallel twin screw barrel iplasticizing unit yetwin screw extruder. Iine zvikamu zviviri zvinoshanda sehurongwa humwe: dhiramu rine maviri anopindirana mabhora akagadzirwa mukati maro, achigadzira mufananidzo-sere muchinjikwa chikamu, uye maviri screws anogara mukati mezvibhorani izvozvo.
Parallelzvinoreva kuti screws dzinochengeta dhayamita imwechete kubva kufeed end kusvika ku discharge end. Bore rinoramba rakaenzana nehurefu hwaro hwose. Ndiwo mutsauko unotsanangura kubva kune conical twin, uko zvese screws uye yakabereka taper yakananga kufa.
Iyo yakafanana fomu inopa mugadziri chikamu chemuchinjiko chinogara chiripo kuti chishande pamwe nehurefu hwese, izvo zvinoita kuti zvive nyore kuvaka michina mirefu ine nzvimbo yekubatanidza, kuburitsa, uye kusanganisa zvikamu. Kuenzanisa pakati pemafomu maviri akafukidzwa mune yeduconical vs parallel gwara.
Iyo Parallel Twin Screw Barrel Inoshanda sei, nhanho nenhanho
- Kudyisa.Material inodonha muhuro yekudyisa uye inomhara pane ese screws kamwechete. Mapatya masiruuru anotora hupfu, maflakes, uye chikafu chisina kujairika icho siruu imwe chete inonetseka kubata.
- Conveying.Iyo screws inotendeuka uye kubhururuka kweimwe screw kunopukuta chiteshi cheimwe. Material anobatwa mumakamuri akaita C-pakati pendege uye kusundirwa mberi nemakanika.
- Melting.Zvidzitiro zvebharel zvinopa chikamu chekupisa. Zvimwe zvacho zvinobva pakugera sezvo zvinhu zvichishandiswa mumukana wakamanikana umo masvikiro anopindirana, inova ndiyo nzvimbo yakanyanya kusimba mumushini.
- Kusanganisa.Kutenderera kwese kunotsemuka, kupeta, uye kusanganisazve rukova runonyungudika. Iyo kupatsanurwa inodzokororwa ndiyo inoparadzira mafiritsi, pigments, uye zvinowedzera zvakaenzana.
- Venting.Padhiramu rine mhepo, chiteshi chinodzika pachiteshi chemhepo saka kudzvanywa kunodonha kusvika pedyo ne zero. Unyoro uye mhepo inopisa zvinopukunyuka ipapo, kazhinji pasi pevacuum.
- Kupomba uye metering.Chikamu chekupedzisira chinovaka kudzvanywa uye chinoburitsa kunyungudika kwakadzikama kune kufa kana pelletizer.
Co-Rotating vs Counter-Kutenderera: Nzira mbiri, Mabasa maviri
Iyo screws inogona kutendeuka munzira imwechete kana munzira dzakapesana. Iyo imwe sarudzo inoshandura hunhu hwemuchina zvachose.

Co-kutendererascrews ndiwo mudziyo wekubatanidza. Kugera kwepamusoro uye kumhanya kwakanyanya kunoparadzira girazi fiber, pigment, uye yekuwedzera zvakakwana, zvinova ndizvo chaizvo zvinodiwa nekomboni yakagadziridzwa.
Counter-inotendererascrews anoita sepositive-displacement pombi. Iyo nip iri pakati pavo inotakura zvinhu kumberi pasi pekumanikidzwa kwakasimba pakuveura kwakaderera, uye ndizvo zvinoda kuomarara PVC, sezvo PVC inodzikisira paunoiveura zvakaomarara. Yeducounter-inotenderera parallel twin screw barrelsyakavakirwa basa iro, uye chemistry kuseri kwayo inogara mune yeduPVC screw barrel guide.
Zvakakwana, Zvikamu, kana Zvisiri-Meshing: Iyo Axis Mazhinji Madhiraivha Skip
Nzira yekutenderera inongova hafu yezvikamu. Yechipiri axis ndeyekuti zvakadzama sei ma screws anobatana, uye mazhinji madhiraivha haambozvitaura.
Our parallel twin screws inouya mumhando nhatu dzemeshing:yakazara meshing, chikamu meshing, uye isiri-meshing. Musiyano ndewekuti kubhururuka kwescrew kunosvika papi mugero reimwe.
- Full meshing.Kubhururuka kweimwe screw kunosvika pamudzi weimwe, kuchisiya mukaha muduku. Iyi ndiyo yakajairika mhando mumapurasitiki extrusion, nekuti iyo yakasimba clearance inopa yakanakisa kuveura uye kusanganisa uye nekupukuta machanera akachena sezvo screws inotendeuka.
- Chikamu meshing.Iyo screws inopindirana, asi zvishoma zvakadzama. Kuendesa kunogara kwakanaka nepo shear inodonha, iyo inokodzera zvinhu zvisingatore kushanda zvine hutsinye.
- Kwete-meshing.Iyo screws inogara padivi nepadivi pasina kubatikana. Muchina uyu unobata padhuze neaviri masiruuru mudhiramu rimwe, nekurapa kwakapfava uye kushoma kuburitsa.
Iyo inoshanda yekutora ndeyekuti "twin screw" yega haitsananguri muchina. Yakazara meshing uye counter-inotenderedza chishandiso chakasiyana kubva kuzere meshing uye co-kutenderera, uye zvese zvinosiyana kubva kune isiri-meshing gadziriro. Paunotsanangura seti yekutsiva, iyo meshing mhando inofanirwa kuenderana nemuchina waunayo.
Sei Mapatya Zvikukuru Achifambisa Zvakasiyana kubva kune Imwe Zvikuru
Siruuru imwe ipombi yekukweva. Inovimba nekukweshana: zvinhu zvinofanirwa kunamatira kumadziro embiru kupfuura zvazvinonamira kune screw, kana inongotenderera panzvimbo panzvimbo yekuenda kumberi.
Kutsamira ikoko kunokonzera matambudziko chaiwo. Hupfu, maflakes, uye chikafu chinotsvedza kana chakaderera-chinorovera hachibati zvakanaka, saka screw inokwira kana kufa nenzara. Mabudiro anobva asiyana nemabatiro anoita zvinhu zviri kubata zuva iroro.
Twin screws inoburitsa zvakanaka. Kubhururuka kwesiruuru imwe kunotsvaira gwara reimwe, saka zvinhu zvinosundirwa pamwe nemuchina zvisinei kuti zvakabata madziro kana kuti kwete. Kubuda kunogara kwakatsiga, uye chikafu chinokunda siruu imwe chete chinopinda pasina kunyunyuta.
Ndokusaka mapatya screws achitonga kusanganisa uye PVC poda basa. Kuenzanisa kwakazara kuri mune yedusingle screw vs twin screw guide.
