Intshayelelo emfutshane ye-conical twin-screw extruder

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 izinto, kwaye ii-extruders ezijikelezayo zisetyenziswa 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 esiphezulu 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.
