PE Conical Twin Screw Barrel

PE conical twin screw mbiya iyi imapangidwa 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).

Migolo ya Nanhaiya ya PE conical twin screw migolo nthawi zambiri imapangidwa kuchokera kuzitsulo zamtundu wapamwamba kwambiri, monga 38CrMoAlA, zomwe zimapereka mavalidwe abwino kwambiri komanso kukana dzimbiri komanso kutentha kwambiri. Nitriding ndi njira zina zimakulitsa kuuma kwa pamwamba ndi kukana kuvala, kumawonjezera moyo wautumiki. Mapangidwe a conical twin-screw barrel amalimbikitsa mawonekedwe oyenda okhazikika. Pakuwonetsetsa kuti chakudya chakuthupi chisasinthasintha komanso kupanikizika panthawi yonseyi, izi zimathandiza kuchepetsa kusinthasintha kwa madzi monga kusinthasintha kapena kugwedezeka, kuchepetsa kuvala kwa zipangizo ndi kukulitsa moyo wa ntchito ya screw ndi migolo.

Migolo ya Nanhaiya ya PE conical twin screw yakhala ikukumana ndi R&D yambiri ndikuwongolera ndipo tsopano yaphatikizidwa 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

PE conical twin screw extruders nthawi zambiri imakhala ndi mapangidwe ozungulira (zomangira ziwirizi zimazungulira molunjika). Izi zimapanga kusiyana kwakung'ono kwapakati, kutulutsa mphamvu zometa ubweya zolimba (kupititsa patsogolo pulasitiki ya PE) komanso kulola kuti ndege zowononga ziyeretsene (kuchepetsa zotsalira zakuthupi ndikuletsa kuwonongeka).

Nanhaiya's PE conical twin screw extruders amakhala ndi chilolezo chaching'ono pakati pa wononga ndege ndi khoma la migolo (nthawi zambiri 0.1-0.3mm). Kuphatikizidwa ndi kumeta ubweya ndi zotulukapo zopangidwa ndi zomangira zozungulira, zimasungunula mwachangu ma granules a PE ndikumwaza mogawana zowonjezera (monga antioxidants ndi colorants). Mapangidwe a screw amapereka malo olowera ndi zosefera zosungunula, zomwe zimawalola kuti azigwira ntchito ndi mbiya yotulutsa mpweya kuti achotse chinyezi komanso kutsika kwamphamvu kwa ma molekyulu kuchokera ku PE kusungunuka, kuwonetsetsa kuti palibe kuwira. Zosefera za kukula kosiyanasiyana zitha kugwiritsidwanso ntchito kusefa zinyalala ndikukulitsa kuyera kwazinthu.

The PE conical twin screw mbiya imagwirizana ndi zida zosiyanasiyana za PE: LDPE (polyethylene low-density), HDPE (high-density polyethylene), LLDPE (linear low-density polyethylene), ndi mitundu ina ya PE. Posintha liwiro la screw ndi ma groove parameter, imatha kutengera zida za PE zokhala ndi ma index osiyanasiyana osungunuka. Itha kugwiritsidwa ntchito potulutsa mapaipi a PE, mbiri, ndi makanema, komanso PE pelletization ndikusintha (monga kulimbitsa magalasi a fiber ndi kusinthidwa kwamoto). Ndizoyenera makamaka kupanga timagulu tating'onoting'ono ndi mitundu yosiyanasiyana ya zinthu za PE.

Zambiri Zamalonda

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.
