I-Intermeshing Conical Twin Screw

I-Nanhaiya screw ingumkhiqizi wokuqala wase-China onguchwepheshe ekukhiqizeni isikulufu esiyi-conical twin screw. Ngesipiliyoni esingaphezu kweminyaka eyishumi emishinini yepulasitiki, sisebenzisa izinqubo zokukhiqiza ezithuthukisiwe kanye nezinto zokusebenza ukudizayina nokwenza izinhlobo eziningi zezikulufu. Imikhiqizo yethu inikeza amanani ancintisanayo futhi ihlanganisa izimakethe eziningi zaseYurophu nezaseMelika. Sibheke ngabomvu ukuba uzakwethu wesikhathi eside e-China.

Isingeniso Somkhiqizo

Lesi sikulufu se-twin conical intermeshing senziwe ngensimbi engu-38CrMoAla. Izinto ezingavuthiwe zibalulekile ekusebenzeni ngezikulufu, futhi sikhetha insimbi enamandla amakhulu nengagugi kubakhiqizi bensimbi abadumile baseShayina abahlangabezana nezindinganiso zikazwelonke (GB/T 3077).

Sisebenzisa inqubo yokugoqa intambo. Le nqubo idala iphrofayili yentambo egcwele, eqinile, ivimbele ukuphuka. Iphinde ilawule iphutha lokuphakama kochungechunge ku-≤0.1mm, iqinisekise ukusebenzelana okufanayo kanye nokunciphisa ukuxega.

Imiphongolo yezikulufi zamawele e-Nanhaiya ehlanganayo ehlanganayo 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

1. Ukudlulisa Okubalulekile: Kuphoqelelwe Futhi Kuzinzile, Akukho Ukugeleza Kwasemuva

Isakhiwo se-intermeshing sidala "igumbi lezinto ezibonakalayo" elivaliwe eliphusha impahla ngendluzula, lisuse ngokuphelele inkinga yokubuyela emuva ehlotshaniswa nezikulufu ezine-meshing ephansi noma ezingena-meshing.

Ukusebenza kahle kokudlulisa akuthintwa kakhulu yi-viscosity yezinto. Ngisho nalapho uphatha izinto ezibonakalayo ezifana namapulasitiki ancibilikisiwe kanye nama-slurries agxilile, izinga lokuphakelayo elizinzile lingagcinwa, kuqinisekiswe ukukhiqizwa okuqhubekayo.

2. Ukuxuba Nokugunda: Umphumela Oqinile, Okufana Kakhulu

Lapho izikulufu ezimbili zihlangana, zenza isenzo esiphindwe kathathu "sokugunda," "ukuxova," kanye "nokuwa" kumpahla, ukudiliza ngokushesha ama-agglomerate wezinto futhi kuzuzwe ukuxutshwa okufanayo okufanayo kwezingxenye ezincane nge-microscope.

Leli khono eliqinile lokugunda lisiza futhi ukuncibilika noma ukusabela. Isibonelo, ku-extrusion yepulasitiki, inganciphisa isikhathi sokuncibilika futhi izuze ikhwalithi yokuncibilika efanayo.

3. Ingcindezi Nezinga Lokushisa: Kuyalawuleka Kakhulu, Kufanelekile Ukusebenza Okunomfutho Ophakeme

Igumbi elivaliwe lisungula futhi ligcine ingcindezi yokusebenza ezinzile, lilenze lifanele izinqubo ezidinga ingcindezi, njengokucindezela kosayizi ku-extrusion yamapayipi epulasitiki kanye nokusabela okucindezelekile kwezinto ezisebenzayo. Isikhathi sokuhlala sento ngaphakathi kwegumbi elivaliwe siyalingana, futhi ukushintshana kokushisa phakathi kwesikulufu nomgqomo kufana kakhulu, okuvumela ukulawula okunembile kwezinga lokushisa elibonakalayo futhi kuvimbele ukushisisa okweqile kwendawo noma ukungalingani kwezinga lokushisa okungase kuholele ekuwohlokeni kwempahla.

4. Ububanzi Besicelo: Izixazululo Ezihlosiwe Zezidingo Zokucubungula Okunzima

Lokhu kulungele ikakhulukazi izinto ezine-viscosity ephezulu, ukunwebeka okuphezulu, futhi okudinga ukuxubana okuhle, okufana namapulasitiki, irabha, izinto zokunamathisela, kanye nezingubo zokugxila okuphezulu.

Uma kuqhathaniswa nezinye izikulufu, izikulufu ze-Nanhaiya ezihlanganisa i-conical twin zinciphisa izinsalela zezinto ezisetshenziswayo, zenza ukuhlanza kube lula ngesikhathi sokushintsha kwezinto futhi kuthuthukise ngokungaqondile ukusebenza kahle kokukhiqiza.

 Izindawo eziyinhloko zokusetshenziswa kwama-extruder angamawele angamawele ahlanganayo ahlanganisa cishe zonke izinyathelo ezibalulekile zenqubo yokucubungula amapulasitiki, kusukela ezintweni ezingavuthiwe ukuya emikhiqizweni ephelile.

1. I-Plastiki Extrusion: Isetshenziselwa ukukhiqizwa kwamapayipi, amaphrofayili (njengamafreyimu eminyango namafasitela), amashidi, amafilimu, izintambo zezintambo, nokunye. Umthamo wayo ophezulu wokudlulisa uqinisekisa ukugeleza okuzinzile kwepulasitiki yokuncibilika, kuyilapho umphumela wayo oqinile wokugunda uvumela ukuxubana okuphelele kwepulasitiki nezithasiselo (njengama-masterbatches nama-antioxidants), ukuqinisekisa ikhwalithi efanayo emkhiqizweni ophelile.

2. I-Plastiki Granulation: Izinsalela zepulasitiki, izinto ezigaywe kabusha, noma izinto ezintsha ziyancibilika, zikhishwe, futhi zisikwe zibe amapellets ngesikulufu. Isakhiwo se-intermeshing siqinisekisa ukuncibilika okuphelele kanye ne-plasticization yepulasitiki, ukuvimbela izigaxa ezingancibiliki kuma-pellets.

3. Ukucutshungulwa kwePlastiki Okukhethekile: Ukucubungula amapulasitiki anokushisa okuphezulu kanye nezidingo zokuxuba, njenge-PVC (i-polyvinyl chloride) ne-PC (i-polycarbonate). Ukulawulwa kwayo okunembile kwezinga lokushisa kuvimbela i-PVC ekuboleni emazingeni okushisa aphezulu, kuyilapho ukuxuba kwayo okufanayo kuqinisekisa izici ezizinzile zemishini yemikhiqizo ye-PC.

Imininingwane

Ukuvunyelwa okunengqondo kudala "indawo yokuvala" ngesikhathi sokusebenza ngezikulufu, kunciphisa ukugeleza emuva kwezinto ezine-viscosity ephezulu ngasekugcineni kokuphakelayo ngaphansi kwengcindezi nokuqinisekisa ukuthunyelwa okuphoqelekile okuphumelelayo. Lokhu kubaluleke kakhulu kuma-extruder angamawele angamawele ahlanganayo. I-Nanhai Ya ilawula ngokuqinile imvume phakathi kwamazinyo amabili ayizikulufu, isebenzisa ukunemba okuphezulu (okufana nokugaya) ukuze kuqinisekiswe imvume efanayo.

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.
