Ukugcina ukusebenza kahle kuma-twin-screw extruder kubalulekile ekukhiqizeni okuphezulu. Isikhathi sokuphumula nokuguga kungakhuphula kakhulu izindleko futhi kuphazamise ukuhamba komsebenzi. Ukusebenzisa amasu afakazelwe kuthuthukisa ukusebenza futhi kunciphisa ukuhlehla kokusebenza. Abakhiqizi kufanele babeke phambili amasu agxile emiphongolweni eqinile ye-twin-screw extruder, ama-twin parallel screw barrel, kanyeama-conical twin screw extruder imiphongolo, kanye nezimo zokucubungula ezenziwe kahle ze-plastic extruder single screw imiphongolo.
Izimbangela Zokugqoka Emiphongolweni Ehlala Kakhulu Ye-Twin-Screw Extruder
Ukubunjwa Kwezinto Ezibalulekile
Ukwakhiwa kwempahla kwemiphongolo ye-twin-screw extruder idlala indima ebalulekile ekuqineni nasekusebenzeni kwayo. Ukukhetha izinto ezifanele kunganciphisa kakhulu ukuguga futhi kwandise isikhathi sokuphila salezi zingxenye. Izimbangela ezijwayelekile zokugqoka ezihlobene nokwakheka kwezinto zifaka:
| Imbangela Yokugqoka | Incazelo |
|---|---|
| Ukukhetha izinto ezingafanele | Amandla okusebenza anganele wesikulufu nomgqomo kunciphisa ubude bazo bempilo. |
| Ubulukhuni bokwelashwa obanele | Ubulukhuni obuphansi busheshisa ukugqoka ezindaweni zokusebenza. |
| Ukunemba kwemishini ephansi | Ukungaqondi kahle nokufakwa kungaholela ekuphambeni nasekuguge ngokushesha. |
| Ukuba khona kwama-fillers kumpahla ekhishwe | Izithako ezifana ne-calcium carbonate noma i-glass fibre zibhebhethekisa ukuguga. |
Izakhi ze-alloying emigqonyeni yezinto zokwakha nazo zithonya ukumelana nokuhuzuka nokugqwala. Isibonelo, i-Ni60 ikhombisa ukumelana okumangazayo ngokumelene nokugqokwa kwe-abrasive, ukunciphisa amanani okuguga kanye nezindleko zokusebenza. Le alloy igcina ubuqotho bemishini emazingeni okushisa aphakeme, iqinisekisa ukuzinza kwenqubo.
Izimo Zokucubungula
Izimo zokucubungulakuthinta kakhulu ukugqokwa kwemiphongolo ye-twin-screw extruder eqinile. Izinto ezifana nezinga lokushisa, ingcindezi, kanye nemvelo yezinto ezicutshungulwayo zingasheshisa ukuguga. Izimo eziyinhloko zokucubungula ezinomthelela ekugqokeni zihlanganisa:
| Isici | Incazelo |
|---|---|
| Abrasive Materials | Ukucubungula izinhlanganisela ezigcwele kakhulu, njengamapulasitiki agcwele ingilazi noma izimpushana zamaminerali, kungasheshisa ukuguga kuzo zombili izikulufu nemiphongolo. |
| Izinga Lokushisa Eziphezulu Nokucindezela | Ukuchayeka isikhathi eside emazingeni okushisa adlulele noma izimo zokucindezela okuphezulu kungenza buthaka umgqomo, okuholela ekugugulekeni. |
| Ukuhlasela Kwamakhemikhali | Ama-polymer athile noma izithasiselo zingase zisabele ngokwekhemikhali nomgqomo, kubangele ukugqwala noma umgodi ngokuhamba kwesikhathi. |
| Isondlo Esibi | Ukuhlolwa okungajwayelekile nokulungiswa okubambezelekile kuvumela ukuguga okuncane ukuthi kuguquke kube umonakalo omkhulu. |
Ukushintshashintsha kwezinga lokushisa nengcindezi ngesikhathi sokusebenza kungase futhi kube nomthelela ngokuphawulekayo ukuphila kwemiphongolo ye-twin-screw extruder. Amazinga okushisa aphezulu okusebenza, ngokuvamile angaphezu kuka-200 °C, ahlanganiswe nomfutho ophezulu, anomthelela ekugugekeni nasekugqwaleni kombhobho nesikulufu. Imiphumela elimazayo yokuncibilika kanye nokucindezeleka komshini ngesikhathi sokusebenza kwenza lezi zinkinga zibe zimbi nakakhulu, okuholela ekulahlekeni kwezinto ezibonakalayo kanye nokwehluleka ekugcineni.
I-Mechanical Stress Factors
Izici zokucindezelwa kwemishini zingesinye isici esibalulekile esinomthelela ekwehlulekeni ngaphambi kwesikhathi emiphongolweni ye-twin-screw extruder. Lezi zingcindezi zingavela ezimweni ezehlukene zokusebenza, okuhlanganisa:
- Ukuguga okubangelwa izinhlayiya eziqinile kusikulufa sokuguguleka se-polymer nendawo yombhobho.
- Ukuguga kokushisa okubangelwa ukushisa okukhulu nokushisisa okungalingani kwesilinda.
- Ukukhathala okubangelwa ukucindezelwa okuphindaphindiwe nemijikelezo yokucindezela, okwenza buthaka izici zesikulufu ngokuhamba kwesikhathi.
Ukulayishwa kwe-cyclic nakho kungabangela ukukhathala nokuguga ezingxenyeni zemiphongolo ye-twin-screw extruder.Izingcindezi ze-Torsional kanye nokugobaingaqala futhi isakaze imifantu, kuyilapho amadiphozithi e-carbide amaholo aholela emifantwini emincane ebusweni bomgodi. Amaphutha afana nezimbobo kanye ne-sediments kunomthelela ekukhuleni okusheshayo nokuhluleka.
Ukuqonda lezi zimbangela zokuguga emiphongolweni eqinile ye-twin-screw extruder kuvumela abakhiqizi ukuthi basebenzise amasu asebenzayo okulungisa nokwenza kahle, ekugcineni kuthuthukise ukusebenza kahle kokukhiqiza.
Izimpawu Zokugqoka Zokuqapha Emiphongolweni Ye-Twin-Screw Extruder
Ukwehliswa kokusebenza
Ama-opharetha kufanele aqaphe ngokucophelela ukuwohloka kokusebenza kuma-extruder amabili-screw. Izimpawu zokuqala zihlanganisa:
