Non-intermeshing Conical Twin Screw

Zomangira zamapasa zomwe sizimalumikizana zimapangidwa kuchokera kuchitsulo 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).

Nanhaiya's non intermeshing conical twin-screw extruder ali ndi maulendo apaulendo osalumikizana. The clearances pakati zomangira ndi pakati wononga ndi mbiya khoma ndi lalikulu (kawirikawiri 0.5-2mm), ndi clearances izi zikhoza kusinthidwa potengera makhalidwe zinthu kupewa anakakamizika extrusion ndi kumeta ubweya kugwirizana ndi intermeshing zomangira. Zomangira zimadulidwa, ndipo ma diameter amachepera pang'onopang'ono kuchokera kumapeto kwa chakudya mpaka kumapeto. Zomangira ziwirizi zimazungulira paokha (ndi liwiro losinthika). Zinthu zimaperekedwa makamaka ndi kukankhana ndi kukanikizana kwa axial kuchokera ku zomangira zozungulira, osati ndi "kukankha" kwa ndege zodutsana. Kudalira makamaka pakuyenda kwachilengedwe kwa zinthu zomwe zili mkati mwa screw channel ndi kusakaniza pang'ono kwa convection, kufanana kwa kubalalika kwa zowonjezera (monga masterbatches ndi zodzaza) ndizosauka, zomwe zimapangitsa kuti zikhale zosayenera kwa zinthu zomwe zimafuna kusakanikirana kwakukulu (monga mafilimu owonekera kwambiri ndi mbiri yolondola).

Migolo ya Nanhaiya yosagwirizana ndi conical twin screw yadutsamo zambiri za R&D ndikuwongolera ndipo tsopano ikuphatikizidwa 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.

Mbali Ndi Kugwiritsa Ntchito

Zotulutsa zapawiri zosalumikizana, chifukwa chosowa kukameta ubweya wolumikizira ndege, zimakhala ndi mphamvu yochepa kwambiri yometa ubweya mkati mwa screw kuposa zotulutsa ziwiri. Izi zimalepheretsa kuwonongeka kapena kusweka kwa ulusi wa zinthu zomwe zimameta ubweya wa ubweya (monga mapulasitiki otsika osungunuka ndi zida zowonjezeredwa ndi fiber).

Amagwiritsidwa ntchito makamaka popanga zinthu zoyambira popanda zowonjezera zovuta, monga mapaipi amadzimadzi a PVC, filimu yaulimi ya PE, ndi ndodo zapulasitiki zosavuta, pomwe kusakanizika kwakukulu sikofunikira kukwaniritsa zofunikira. Mitsuko yawo yozama ya wononga ndi kutulutsa kwakukulu kumapereka madzi okhazikika, osungunuka kwambiri, kuwapanga kukhala oyenera ntchito zomwe zimafuna kutulutsa kwakukulu koma zosafunikira kusakaniza mwatsatanetsatane, monga mapaipi akuluakulu a PVC (monga DN300 ndi pamwamba) ndi mapepala apulasitiki okhuthala.
