Chinhu chimwe chete chakakosha chemuchina che screw extruder is screw.Magadzirirwo akakodzera ejiometry ye extruder screw akakosha kukosha pakushanda kwakakodzera kweiyo extruder.
Chinhu chimwe chakakosha chemuchina che ascrew extruderis the screw.Magadzirirwo akakodzera ejiometry yeextruder screw ndeyekukosha kwakakosha pakushanda kwakanaka kweiyo extruder.Kana kusagadzikana kwekutakura zvinhu kukaitika nekuda kweiyo isina kufanira screw geometry, kunyangwe iyo yakaomesesa komputa yekudzora system haigone kugadzirisa dambudziko.Screw dhizaini inowanzoonekwa seyakawanda yehunyanzvi pane sainzi.Nekuda kweizvozvo, kusanzwisisa pamusoro pemamwe maficha escrew dhizaini achiri kuwanda nhasi.Sezvo dzidziso yesingle screw extrusion ikozvino yakanyatso gadzirwa, dhizaini yezvikumbiro zveimwe screw extruders inogona kuve yakavakirwa pane yakasimba engineering misimboti.Saka, screw dhizaini yeimwe screw extruders haifanirwe kunge ichiri hunyanzvi, asi sainzi yakavakirwa zvakasimba pamisimboti yepolymer processing engineering.
Nehurombo, vanhu vanobatanidzwa mukugadzira screw havawanzo kuenderana neextru-sion theory.Nekuda kweizvozvo, akawanda eextruder screws ari kushandiswa nhasi anoita zvakanyanya pasi pepamusoro soro rinogoneka kuita, chete nekuda kweiyo isina kufanira screw design.Iyi iscrew ine pitch inoramba iripo uye pitch yakaenzana nedhayamita yescuru; iyi pitch inoenderana nehelix angle ye17.66.Zvinogona kuratidzwa zviri nyore kuti sikweya pitch iri kure nekwakanaka maererano nekunyunguduka uye kunyunguduka kuendesa kune akati wandei mapolymer.Ichi chokwadi chave chichizivikanwa kubva kutanga kwema1950, asi akawanda extruder screws ari kushandiswa nhasi achiri kushandisa anogara ari square pitch dhizaini.
Chinhu chingave chave chakonzera mamiriro ezvinhu mukugadzira screw ndechekuti pasati pave neruzivo rwakakwana rwekuita ne screw design.Chinangwa chechitsauko chino ndechekuratidza kuti extrusion theory inogona kushandiswa sei kugadzira extruder screws.Tine tarisiro, izvi zvinopa hwaro hwakasimba, hwakavakirwa pamisimboti yeinjiniya, kubva pairi nani uye inoshanda zvakanyanya screw dhizaini inogona kuvandudzwa mune ramangwana.Misimboti yekugadzira screw haina kukosha chete mukugadzira zvitsva zveextruder screws, asiwo mukuongorora kwekugadzirisa matambudziko eiyo iripo extrusion mutsara.Izvo zvakakosha kuti ukwanise kuziva kana dambudziko rine chekuita nekusagadzikana screw dhizaini kana kune chimwe chikamu chemaitiro.Nekudaro, ruzivo rwemisimboti yekutanga screw dhizaini yakakosha kune wese munhu ane chekuita neextruders.
