Ipayipi le-PVC lomphongolo wesikulufa esisodwa lidlala indima ebalulekile enqubweni ye-plastic extrusion, lincibilika kahle futhi lilolonge impahla ye-PVC ibe amapayipi aqinile, ahlala isikhathi eside. Ngo-2022, ama-screw extruder oyedwa ayebusa imakethe, anikela ku-63.2% wesabelo semali engenayo emhlabeni wonke, okubonisa ukwethembeka nokusetshenziswa kwawo okubanzi.Izimboni ze-Pvc pipe single screw barrelfuthiamafekthri e-plastic screw barrel eyodwasebenza ngokukhethekile ekwenzeni lezi zingxenye ngokunemba, ukuqinisekisa ukusebenza okungaguquki kanye nekhwalithi ephezulu.
Izici Eziyinhloko ze-PVC Pipe Single Screw Barrels
Izingxenye kanye Nomklamo
Ukwakhiwa kwepayipi le-PVCumphongolo wesikulufa esisodwaiyasebenza futhi iqondile. Isakhiwo sayo sihlanganisa umphongolo oyicylindrical nesikulufu esijikelezayo, esisebenza ndawonye ukucubungula impahla ye-PVC. I-screw's helical grooves iqinisekisa ukuxutshwa okufanele nokuncibilika kwezinto, kuyilapho umgqomo uhlinzeka ngendawo elawulwayo yokukhishwa.
Ukucaciswa okubalulekile kobuchwepheshe kwalezi zingxenye kuhlanganisa:
| Ukucaciswa | Imininingwane |
|---|---|
| Ububanzi | Ф16-Ф300 |
| I-Aspect ratio | L/D=15-40 |

- I-Nitride Layer DepthUbukhulu: 0.5-0.8mm
Lezi zici ziqinisekisa ukuthi umgqomo ungamelana namazinga okushisa aphezulu kanye nezingcindezi ngesikhathi senqubo yokukhipha. Ikhwalithi yokwakha eqinile inciphisa ukuguga, yehlise izindleko zokulungisa kanye nesikhathi sokuphumula. Abakhiqizi abafana ne-Zhejiang Jinteng Machinery Manufacturing Co., Ltd. basebenzisa imishini ye-CNC ethuthukisiwe nobuchwepheshe bokwelapha ukushisa ukuze bafinyelele la mazinga aphezulu.
Amasistimu wokushisisa nokupholisa
Amasistimu wokushisisa nokupholisa asebenzayo abalulekile ekugcineni amazinga okushisa angashintshi phakathi nenqubo yokukhipha. Isistimu yokushisisa yomphongolo iqinisekisa ukuthi impahla ye-PVC iyancibilika ngokulinganayo, kuyilapho isistimu yokupholisa ivimbela ukushisa ngokweqile futhi igcina ikhwalithi yomkhiqizo.
Ucwaningo oluhlaziya imiphumela yesivinini sesikulufu nezinga lokushisa ekusebenzeni kwe-extrusion lubonise ukubaluleka kokulawula izinga lokushisa okunembile. Ama-transducer okucindezela izinga lokushisa afakwe ngaphambi nangemuva kwezimo zepuleti le-breaker ngesikhathi sangempela, okuqinisekisa ukusebenza kahle. Ukulungiswa kwesivinini sesikulufu, izinga lokushisa elincibilikayo, nezinga lokugeleza kuthinta ngokuqondile ikhwalithi yomkhiqizo wokugcina.
Lezi zinhlelo azithuthukisi ukusebenza kahle kuphela kodwa futhi zithuthukisa ukuhambisana kwenqubo yokukhipha, okwenza imiphongolo yesikulufa yepayipi elilodwa le-PVC ibe ukukhetha okuthembekile kubakhiqizi.
Isebenza kanjani i-PVC Pipe Single Screw Barrels
Indima Yesikulufu ku-PVC Extrusion
Isikulufu emgqonyeni wesikulufa wepayipi elilodwa le-PVC sisebenza njengomgogodla wenqubo yokukhipha. Isiza ukunyakaza, ukuncibilika, kanye nokuxutshwa kwezinto ze-PVC ngaphakathi komgqomo. Idizayini ye-helical yesikulufu iqinisekisa ukusatshalaliswa okufanayo kokushisa nokucindezela, okubalulekile ekuzuzeni ikhwalithi yomkhiqizo engaguquki.
- Imiklamo yezikulufo elungiselelwe ibonise ukuthuthuka okumangalisayo kokusebenza kahle. Ngokwesibonelo:
- Ukukhiqizwa kokukhiqiza kuphindwe kabili kusuka kumathani angu-4.5 kuya ku-8.5 amathani ngokushintshana kuhlelo lokusebenza lomhlaba wangempela.
- Ukuvumelana nezimo okuthuthukisiwe ekucubunguleni izinto ezihlukahlukene nezithasiselo kuthuthukise ikhwalithi yomkhiqizo.
- Imiklamo yezikulufo efanelanisiwe inciphisa ukusetshenziswa kwezinto, ikhulisa inzuzo.
Ucwaningo lwezazi luqhubeka lugcizelela ukubaluleka kokuklama isikulufu.

Le miphumela igqamisaindima ebalulekile yesikulufaekuqinisekiseni ukusebenza kahle nokuthembeka kokukhiqizwa kwamapayipi e-PVC.
Inqubo yokuncibilika nokuxuba
Iukuncibilika nokuxuba inqubongaphakathi kwepayipi le-PVC umphongolo wesikulufa esisodwa kuwukulandelana okwenziwe ngokucophelela. Njengoba impahla ye-PVC ingena emgqonyeni, ukuzungezisa kwesikulufu kudala ukungqubuzana nokushisa, kuncibilike kancane kancane. Ama-helical grooves kusikulufu asiza ukuxubana okuphelele, ukuqinisekisa ukuthi izithasiselo nezigcwalisi zisatshalaliswa ngokulinganayo.
- Ucwaningo oluhlola ama-barrier-screw extruder luveza ukusebenza kahle kwawo ekuthuthukiseni i-polymer extrusion, okuhlanganisa i-PVC.
- Ucwaningo lokulandelana kwepulasitiki luhlinzeka ngedatha yokuhlola esekela ukwenziwa kahle kwezinqubo ze-extrusion.
Ukulawula izinga lokushisa kudlala indima ebalulekile kule nqubo. Ukulungiswa okunembayo kwesivinini sesikulufu kanye nezinga lokushisa elincibilikayo kuqinisekisa ukuthi okokusebenza kufinyelela ukuvumelana okufunayo. Le ndlela yokucophelela inciphisa amaphutha futhi ithuthukise ikhwalithi yomkhiqizo wokugcina.
Ukuqinisekisa Ukusebenza Nokungaguquguquki
Ukusebenza kahle nokungaguquguquki kubaluleke kakhulu ekukhishweni kwamapayipi e-PVC. Abakhiqizi basebenzisa izindlela ezithuthukisiwe zokugcina ukuqina kwenqubo nokunciphisa ukuhlukahluka. I-Statistical Process Control (SPC) ihlonza ukuhluka futhi izinze izinqubo, kuyilapho indlela ye-DMAIC ye-Six Sigma's DMAIC iqhubeka iphucula amakhono okukhiqiza.
- Idatha yomhlaba wangempela ibonisa umthelela wokuthuthukiswa kwenqubo:
- Isistimu yokutholwa kwedatha yehlise amanani okulahlwa kusuka ku-15% kuya ku-5% phakathi nezinyanga ezintathu.
- Ukuqapha kwesikhathi sangempela kuvimbele imikhiqizo engaphandle kwe-spec, kuqinisekisa amazinga aphezulu.
- Ukonga kwezindleko kwalolu hlelo kwabonakala njengoba lazikhokhela ngokushesha ngokuncipha kokumosha.
Lawa maqhinga awathuthukisi ukusebenza kahle kuphela kodwa futhi aqinisekisa ikhwalithi yomkhiqizo engaguquki, okwenza imiphongolo yepayipi elilodwa le-PVC ibaluleke kakhulu ekukhiqizeni kwesimanje.
