I-PE Conical Twin Screw Barrel

Le PE conical twin screw barrel yenziwe ngensimbi engu-38CrMoAla. Izinto ezingavuthiwe zibalulekile ekusebenzeni ngezikulufu, futhi sikhetha insimbi enamandla amakhulu nengagugi kubakhiqizi bensimbi abadumile baseShayina abahlangabezana nezindinganiso zikazwelonke (GB/T 3077).

Imiphongolo yesikulufu ye-PE ye-Nanhaiya ye-PE conical ivamise ukwakhiwa ngezinsimbi ze-alloy zekhwalithi ephezulu, njenge-38CrMoAlA, enikeza ukuguga okuhle kakhulu nokungagqwali namandla ezinga lokushisa eliphezulu. I-Nitriding nezinye izinqubo zithuthukisa ubulukhuni bobuso kanye nokumelana nokuguga, kunwebe impilo yesevisi. Idizayini ye-conical twin-screw barrel ikhuthaza izici zokugeleza ezizinzile. Ngokuqinisekisa ukuphakelwa kwempahla engaguquki kanye nengcindezi kuyo yonke inqubo yokukhipha, lokhu kusiza ukunciphisa ukugeleza okudidayo njengokuguquguquka noma ukushayeka, ukwehlisa ukuguga kwezinto zokusebenza nokwelula impilo yesevisi yesikulufu nemiphongolo.

Imiphongolo ye-PE conical twin screw ye-Nanhaiya yenze i-R&D eminingi kanye nentuthuko futhi manje isihlanganiswe emigqeni yokukhiqiza yabakhiqizi abahlukahlukene, ifinyelela ukusebenza kwesimanjemanje. Sinikeza iwaranti yeminyaka engu-1-2, kuye ngesilinganiso esithile sokwengezwa kwempahla. Imiphongolo ye-Nanhaiya ingena kunqubo yokufaka i-nitriding, enongqimba oluwugqinsi olungu-2mm lwengxube ye-nickel-tungsten eshiselwe ezindaweni ezithandwa kakhulu. Lokhu kukhulisa ubulukhuni bobuso bomgqomo ukusuka ku-HRC55-60 kuye ngaphezu kwe-HRC65, kukhulisa ukumelana nokugqokwa izikhathi ezi-2-4.

Isici Futhi Isicelo

Ama-PE conical twin screw extruder ngokuvamile afaka idizayini ephendukisayo (izikulufu ezimbili zizungezisa izinhlangothi eziphambene). Lokhu kudala igebe elincane lokuhlangana, okukhiqiza amandla aqinile okugunda (okugqugquzela ukwenziwa kwepulasitiki kwe-PE) kuyilapho kuvumela futhi izindiza eziyisikulufu ukuthi zihlanzene (ukunciphisa izinsalela zezinto ezibonakalayo nokuvimbela ukuwohloka).

Ama-extruder angamawele angamawele we-Nanhaiya we-PE afaka indawo encane phakathi kwezindiza ezikulufa kanye nodonga lomgqomo (imvamisa engu-0.1-0.3mm). Kuhlanganiswe nemiphumela yokugunda kanye ne-extrusion ekhiqizwe izikulufu eziphikisayo, zincibilikisa ngokushesha ama-PE granules futhi zihlakaze ngokulinganayo izithasiselo (njengama-antioxidants nama-colorants). Idizayini yesikulufu inikeza isikhala sezikhala nezihlungi ezincibilikayo, okuzivumela ukuthi zisebenze nesistimu yokukhipha umoya yomphongolo ukuze kususwe umswakama kanye nokuguquguquka kwesisindo esiphansi samangqamuzana ekuncibilikeni kwe-PE, okuqinisekisa umkhiqizo ongenabhamuza. Izihlungi zosayizi abahlukahlukene bezimbotshana zingasetshenziswa futhi ukuhlunga ukungcola futhi kuthuthukise ukuhlanzeka komkhiqizo.

I-PE conical twin screw barrel ihambisana nezinhlobonhlobo zezinto zokusetshenziswa ze-PE: i-LDPE (i-polyethylene ephansi-density), i-HDPE (i-polyethylene ephezulu kakhulu), i-LLDPE (i-linear low-density polyethylene), nezinye izinhlobo ze-PE. Ngokulungisa isivinini sesikulufu namapharamitha we-groove, ingakwazi ukufaka izinto zokusetshenziswa ze-PE ezinezinkomba ezincibilikisiwe ezihlukene. Ingasetshenziselwa ukukhishwa kwamapayipi e-PE, amaphrofayili, namafilimu, kanye ne-PE pelletization nokuguqulwa (njengokuqinisa ingilazi ye-fiber kanye nokuguqulwa kwe-flame retardant). Ifaneleka ngokukhethekile ukukhiqizwa kwamaqoqo amancane kanye nezinhlobonhlobo zemikhiqizo ye-PE.

Imininingwane Yomkhiqizo

Ukushisa okuthuthukisiwe, ukunemba kwemishini, nezinqubo ze-nitriding ziqinisekisa ukusebenza okuphelele kwezingxenye ezibalulekile.

Izindawo ezisengozini ye-screw kanye nomgqomo ziqiniswa nge-nickel-tungsten alloy layer, ezifinyelela ungqimba oluwugqinsi luka-2-3mm futhi kuthuthukisa kakhulu ukumelana nokugqokwa.
