Intermeshing Conical Twin Screw

Nanhaiya screw ndi wopanga koyambirira ku China yemwe amagwira ntchito yopanga intermeshing conical twin screw. Pokhala ndi zaka zopitilira khumi mumakina apulasitiki, timagwiritsa ntchito njira zotsogola zopangira ndi zida kupanga ndikupanga mitundu ingapo yama screw. Zogulitsa zathu zimapereka mitengo yopikisana ndipo zimaphimba misika yambiri yaku Europe ndi America. Tikuyembekezera kukhala bwenzi lanu kwa nthawi yayitali ku China.

Chiyambi cha Zamalonda

Izi intermeshing conical twin screw amapangidwa kuchokera ku chitsulo cha 38CrMoAla. Zinthu zopangira zitsulo ndizofunikira kwambiri kuti ziwonongeko, ndipo timasankha zitsulo zolimba kwambiri komanso zosavala kuchokera kwa opanga zitsulo otchuka aku China zomwe zimakwaniritsa miyezo ya dziko (GB/T 3077).

Timagwiritsa ntchito njira yopangira ulusi. Izi zimapanga mbiri yowonjezereka, yamphamvu ya ulusi, kuteteza kusweka. Imawongoleranso cholakwika cha ulusi mpaka ≤0.1mm, kuwonetsetsa kuyanjana kofanana ndikuchepetsa kumasula.

Nanhaiya's intermeshing conical twin screw migolo yadutsamo zambiri za R&D ndikuwongolera ndipo tsopano akuphatikizidwa mumizere yopangira opanga osiyanasiyana, ndikukwaniritsa magwiridwe antchito apamwamba. Timapereka chitsimikizo cha zaka 1-2, kutengera kuchuluka kwazinthu zowonjezera. Migolo ya Nanhaiya imadutsa njira yopangira nitriding, yokhala ndi 2mm wandiweyani wa nickel-tungsten alloy spray-welded pamadera omwe amavala kwambiri. Izi zimawonjezera kuuma kwa mbiya kuchokera ku HRC55-60 kupita ku HRC65, kukulitsa kukana kuvala ndi nthawi 2-4.

Mafotokozedwe a conical twin screw ndi mbiya

Mbali Ndi Kugwiritsa Ntchito

1. Kutumiza Zinthu: Kukakamizidwa ndi Kukhazikika, Palibe Kubwerera

Mapangidwe a intermeshing amapanga "chipinda cham'kati" chotsekedwa chomwe chimakankhira zinthuzo mokakamiza, kuthetsa vuto la backflow lomwe limagwirizanitsidwa ndi zomangira zotsika kapena zopanda ma meshing.

Kutumiza mwachangu sikukhudzidwa kwambiri ndi kukhuthala kwa zinthu. Ngakhale pogwira zinthu zowoneka bwino monga mapulasitiki osungunuka ndi ma slurries okhazikika kwambiri, kuchuluka kwa chakudya chokhazikika kumatha kusungidwa, kuonetsetsa kuti akupangidwa mosalekeza.

2. Kusakaniza ndi Kumeta ubweya: Mphamvu Yamphamvu, Yofanana Kwambiri

Pamene awiri zomangira intermesh, iwo amachita katatu kanthu "kumeta ubweya," "kukanda," ndi "kugwa" pa zinthu, mwamsanga kuswa agglomerates zakuthupi ndi kukwaniritsa microscopically yunifolomu kusanganikirana kwa zigawo zikuluzikulu.

Kumeta kolimba kumeneku kumathandizanso kuti zinthu zisungunuke kapena kuchitapo kanthu. Mwachitsanzo, mu pulasitiki extrusion, akhoza kufupikitsa nthawi kusungunuka ndi kukwaniritsa yunifolomu kusungunuka khalidwe.

3. Kupanikizika ndi Kutentha: Kuwongolera Kwambiri, Koyenera Kugwira Ntchito Kwambiri

Chipinda chotsekedwa chimakhazikitsa bwino ndikusunga mphamvu yokhazikika yogwirira ntchito, ndikupangitsa kuti ikhale yoyenera njira zomwe zimafunikira kupanikizika, monga kuthamanga kwapaipi ya pulasitiki ndikutulutsa kwapaipi yamagetsi. Nthawi yokhala mkati mwa chipinda chotsekedwa ndi yofanana, ndipo kutentha kwapakati pakati pa wononga ndi mbiya kumakhala kofanana kwambiri, zomwe zimathandiza kuwongolera bwino kutentha kwa zinthu komanso kupewa kutenthedwa kwapadera kapena kusafanana kwa kutentha komwe kungayambitse kuwonongeka kwa zinthu.

4. Kuchuluka kwa Ntchito: Mayankho Omwe Akuwatsogolera pa Zosowa Zovuta Zokonza

Izi ndizofunikira makamaka pazida zokhala ndi kukhuthala kwakukulu, kusungunuka kwapamwamba, ndipo zimafuna kusakanikirana bwino, monga mapulasitiki, mphira, zomatira, ndi zokutira zokwera kwambiri.

Poyerekeza ndi zomangira zina, zomangira za Nanhaiya zopangira ma conical twin-screw zimachepetsa zotsalira mkati mwa zida, kumathandizira kuyeretsa pakasintha zinthu komanso kukonza bwino kupanga.

 Magawo oyambira ogwiritsira ntchito ma intermeshing conical twin-screw extruders amaphimba pafupifupi gawo lililonse lofunikira pakukonza mapulasitiki, kuchokera kuzinthu zopangira mpaka zomalizidwa.

1. Pulasitiki Extrusion: Amagwiritsidwa ntchito popanga mapaipi, mbiri (monga mafelemu a pakhomo ndi mawindo), mapepala, mafilimu, zophimba chingwe, ndi zina. Kuthamanga kwake kwakukulu kumatsimikizira kusungunuka kwa pulasitiki kusungunuka, pamene mphamvu yake yometa ubweya imalola kusakaniza bwino kwa pulasitiki ndi zowonjezera (monga masterbatches ndi antioxidants), kuonetsetsa kuti yunifolomu yamtengo wapatali idzakhala yabwino.

2. Pulasitiki Granulation: Zakale za pulasitiki, zinthu zobwezerezedwanso, kapena zinthu zatsopano zimasungunuka, kutulutsa, ndikudulidwa kukhala ma pellets kudzera pa screw. Mapangidwe a intermeshing amaonetsetsa kuti pulasitiki isungunuke bwino ndi kuyika pulasitiki, kuteteza zilonda zosasungunuka mu pellets.

3. Pulasitiki Yapadera Yopangira Pulasitiki: Kukonza mapulasitiki okhala ndi kutentha kwakukulu ndi zofunikira zosakaniza, monga PVC (polyvinyl chloride) ndi PC (polycarbonate). Kuwongolera kwake kutentha kumalepheretsa PVC kuwonongeka pa kutentha kwakukulu, pamene kusakaniza kwake yunifolomu kumatsimikizira kukhazikika kwa makina azinthu za PC.

Tsatanetsatane

Kuloledwa koyenera kumapanga "malo osindikizira" panthawi yogwiritsira ntchito screw, kuchepetsa kubwezeredwa kwa zinthu zowoneka bwino kwambiri mpaka kumapeto kwa chakudya mopanikizika ndikuwonetsetsa kuti kutumizidwa mokakamizidwa. Izi ndizofunikira makamaka pakuphatikiza ma conical twin-screw extruders. Nanhai Ya amalamulira mosamalitsa chilolezo pakati pa mano awiri wononga, ntchito mkulu-mwatsatanetsatane Machining (monga akupera) kuonetsetsa yunifolomu chilolezo.

Kutentha kwapamwamba, kukonza makina olondola, ndi njira za nitriding zimatsimikizira magwiridwe antchito azinthu zazikuluzikulu.

Madera omwe ali pachiwopsezo cha screw ndi mbiya amalimbikitsidwa ndi nickel-tungsten alloy layer, kukwaniritsa 2-3mm wandiweyani wosanjikiza ndikuwongolera kwambiri kukana kuvala.
