Pipe ea PVC, boto le lakane kaofela li matha holim'a sekoti sa conical twin screw barrel, empa e nepahetseng e fapana ka boemo ba screw, tlhahiso mme - haholo-holo - ts'ireletso ea liaparo. Pipe e rata tlhahiso e tsitsitseng le khatello; foam board le sheet li tsamaisa li-filler tse holimo 'me li hloka khanyetso e matla ea abrasion. Fumana boholo bo lumellanang le extruder ea hau, ebe u khetha nitrided kapa bimetallic ho latela hore na foromo ea hau e na le filler e kae.

Conical twin screw extruder ke mochini oa extrusion o tsepamisitsoeng ke PVC o nang le li-screws tse peli tse tapered, tse intermeshing - bophara ba pheletso ea phepelo, e tšesaane qetellong ea lefu. Geometry ea conical e fana ka torque e phahameng le khatello e matla ka bolelele ba komporo, e e etsa mochini o tloaelehileng oa phala ea PVC, profil, boto le tlhahiso ea WPC.

Moqomo oa conical twin screw barrel ke karolo e tapered, e nang le mafahla a extrusion moo likurufu tse peli tsa khoho li potolohang ka har'a moqomo o ts'oanang oa conical. Geometry ea tapered e fana ka phepo e matla le khatello e phahameng ka bolelele bo khuts'oane, ke ka lebaka leo sekoti sa conical le barrel e leng khetho e tloaelehileng bakeng sa phala ea PVC, profil, sheet le WPC extrusion.

Moqomo o tsofetseng oa ho bopa ente oa u lemosa pele o hloleha. Sheba matšoao a mahlano: boima ba sethunya se hoholehang, matheba a matšo a khutlang ka mor'a ho hloekisoa, ho phahama ha boima ba enjene ka molumo o le mong, bofokoli ba splay kapa bokaholimo, le ho fola butle. E 'ngoe ea tsena e ka ba le lisosa tse ling; tse peli kapa tse tharo 'moho, li tsamaea ka tsela e fosahetseng ka libeke tse ngata, li supa ka ho hlaka holim'a sekoti se tsofetseng le barrel. Netefatsa ka caliper pele u kenya sebaka.

The screw barrel ke motheo oa mochini oa hau oa ho bopa ente. E qhibilihisa polasetiki ea hau, ea e kopanya, 'me e e sutumelletsa ka har'a hlobo - potoloho ka mor'a potoloho, ka lilemo. Ha e fosahetse bakeng sa kopo ea hau, u e bona hohle: boima ba sethunya bo sa tsitsang, bofokoli ba bokaholimo, matheba a matšo, le likhahla tse ntseng li phahama. Tataiso ena e akaretsa ntlha e 'ngoe le e 'ngoe ea liqeto e le hore u ka e fumana hantle lekhetlo la pele.

Karo-karolelano ea ente ea screw L/D ke bolelele ba ho sebetsa bo arotsoeng ka bophara ba sekoti, 'me boholo ba lisebelisoa tsa ente li sebetsa ka 18:1 ho isa ho 25:1. Mona ke seo ho seng leqephe le u bolellang sona: u ke ke ua fetola L/D mochine oo u seng u ntse u e-na le oona. Bolelele bo tsitsitsoe ke barrel. Seo u ka se fetolang ke bophara ba screw, le ka har'a barrel e tsitsitseng eo khetho e le 'ngoe e tsamaisang L/D, bokhoni ba ho thunya, le khatello ea ente hammoho, ka mahlakoreng a fapaneng. Sekurufu se senyane se fana ka L/D e phahameng, sethunya se senyane, le khatello e eketsehileng. Bapisa khoebo eo le resin ea hau le karolo ea hau, 'me lipotso tse ngata tsa L/D lia araba.
