I-Conical twin-screw extruders yahlulwe ibe: i-conical co-roating twin-screw extruders kunye ne-conical counter-roting twin-screw extruders.
Xa i-conical co-phase twin-screw extruder isebenza, izikrufu ezimbini zijikeleza kwicala elinye.
Umahluko phakathi kwayo kunye ne-conical counter-roting twin-screw extruder kukuba i-gear ephakathi yongezwa kwibhokisi yokusabalalisa ukufezekisa umphumo wokuba izikrufu ezimbini zijikeleze kwicala elinye. Inokuhlangabezana kakhulu neemfuno zokulungiswa kwezinto.
Iiparamitha eziphambili ze-twin-screw extruder
1. I-diameter yegama le-screw. Idayamitha ye-screw ebizwa ngokuba yi-screw ibhekisa kwidayamitha yangaphandle yesikrufu, kwi-mm. Kwizikrufu eziguquguqukayo zediameter (okanye tapered), i-screw diameter lixabiso eliguquguqukayo, elimelwe ngokubanzi ngedayamitha encinci kunye nedayamitha enkulu, efana ne: 65/130. Ubukhulu bedayamitha ye-twin-screw, inkulu umthamo wokucubungula umatshini.
2. Umyinge wenkalo yesikrufu. Umlinganiselo we-aspect ratio ye-screw ibhekisela kumlinganiselo wobude obusebenzayo ukuya kububanzi obungaphandle be-screw. Ngokubanzi, umyinge we-aspect ratio ye-integral twin-screw extruder iphakathi kwe-7-18. Kwi-extruders ye-twin-screw edibeneyo, i-aspect ratio iyaguquguquka. Ukususela kumbono wophuhliso, umlinganiselo we-aspect ratio unomkhwa wokunyuka ngokuthe ngcembe.
3. Ukuqhuba isikrufu. I-steering of screw inokwahlulwa ibe kwicala elifanayo kunye nelinye icala. Ngokubanzi, ii-twin-screw extruders ezijikelezayo zisetyenziswa kakhulu ekuxubeni izixhobo, kwaye i-counter-roting extruders isetyenziswa kakhulu kwiimveliso ezikhuphayo.
4. Uluhlu lwesantya se-screw. Uluhlu lwesantya se-screw lubhekisela kuluhlu phakathi kwesantya esisezantsi se-screw kunye nesantya esiphezulu (ixabiso elivumelekileyo). I-twin-screw extruder ejikelezayo inokujikeleza ngesantya esiphezulu, kwaye isantya esiqhelekileyo se-counter-roting extruder yi-0-40r / min kuphela.
5. Amandla okuqhuba. Amandla okuqhuba abhekisa kumandla emoto eqhuba isikrufu, kwaye iyunithi yi kw.
6. Isiphumo. Isiphumo sibhekisa kubungakanani bezinto ezikhutshiweyo ngeyure, kwaye iyunithi yikg/h.
