Sravana Sameeralu Serial 4th Conical Twin Screw Barrel

Iyi PE conical twin screw barrel inogadzirwa kubva ku38CrMoAla simbi. Raw material yakakosha pakukora mashandiro, uye tinosarudza simbi yakasimba-yakasimba uye isingapfeki kubva kune vane mukurumbira vekuChina vanogadzira simbi inoenderana nemitemo yenyika (GB/T 3077).

Nanhaiya's PE conical twin screw barrels anowanzo gadzirwa kubva emhando yepamusoro alloy simbi, senge 38CrMoAlA, iyo inopa yakanakisa kupfeka uye kugwinya kuramba uye yakakwirira-tembiricha simba. Nitriding uye mamwe maitiro anowedzera kuoma kwepasi uye kupfeka kuramba, kuwedzera hupenyu hwebasa. Iyo conical twin-screw barrel dhizaini inosimudzira yakagadzikana kuyerera maitiro. Nekuona kusawirirana kwekudya uye kudzvanywa mukati meiyo extrusion process, izvi zvinobatsira kuderedza kuyerera anomalies sekuchinja-chinja kana pulsations, kuderedza kupfeka kwemidziyo uye kuwedzera screw uye mbiya sevhisi hupenyu.

Nanhaiya's PE conical twin screw barrels yakapfuura akawanda R&D uye kuvandudzwa uye ikozvino yakabatanidzwa mumitsetse yekugadzira yakasiyana-siyana yevagadziri, kuwana mamiriro-e-the-art kuita. Isu tinopa 1-2 gore waranti, zvichienderana neiyo chaiyo yekuwedzera reshiyo. Madhiramu eNanhaiya anoita nitriding process, ane 2mm gobvu layer yenickel-tungsten alloy spray-welded panzvimbo dzinonyanya kupfeka. Izvi zvinowedzera kuoma kwepamusoro kwebhariya kubva kuHRC55-60 kusvika pamusoro peHRC65, inowedzera kupfeka kuramba ne2-4 nguva.

Parameter (Spication)

Feature uye Application

PE conical twin screw extruders inowanzo ratidza dhizaini inotenderedza (ma screws maviri anotenderera akatarisana). Izvi zvinogadzira diki intermeshing gap, ichigadzira mauto akasimba ekugera (kusimudzira PE plasticization) ukuwo ichibvumira ndege dze screw kuti dzichenese (kuderedza zvakasara uye kudzivirira kuparara).

Nanhaiya's PE conical twin screw extruders inoratidzira diki clearance pakati pescrew ndege nemadziro edhiramu (kazhinji 0.1-0.3mm). Yakasanganiswa neiyo shear uye extrusion mhedzisiro inogadzirwa neanopotera-inotenderera screws, inokurumidza kunyungudutsa PE granules uye zvakaenzana kuparadzira zvinowedzera (senge antioxidants uye colorants). Iyo screw dhizaini inopa nzvimbo yevents uye inonyungudutsa mafirita, ichivabvumira kuti vashande neiyo barrel's exhaust system kubvisa hunyoro uye yakaderera-mamorekuru-huremu huremu kubva kuPE kunyunguduka, kuve nechokwadi chekuti chigadzirwa chisina bubble. Mafirita emhando dzakasiyana dzepore anogona zvakare kushandiswa kusefa tsvina uye kuwedzera kuchena kwechigadzirwa.

Iyo PE conical twin screw barrel inowirirana nemhando dzakasiyana dzePE raw materials: LDPE (yakaderera-density polyethylene), HDPE (yakakwirira-density polyethylene), LLDPE (linear yakaderera-density polyethylene), uye mamwe marudzi ePE. Nekugadzirisa screw kumhanya uye groove paramita, inogona kugarisa PE mbishi zvinhu zvine akasiyana melt indexes. Inogona kushandiswa kuwedzeredza mapaipi ePE, profiles, uye mafirimu, pamwe nePE pelletization uye gadziriso (senge girazi fiber reinforcement uye flame retardant modification). Inonyanya kukodzera kugadzirwa kwezvikwata zviduku uye zvakasiyana-siyana zvezvigadzirwa zvePE.

Product Details

Yepamberi tempering, chaiyo machining, uye nitriding maitiro anovimbisa kushanda kwakazara kwezvinhu zvakakosha.

Nzvimbo dzisina njodzi dze screw uye mbiya dzakasimbiswa ne nickel-tungsten alloy layer, kuwana 2-3mm gobvu layer uye zvakanyanya kunatsiridza kupfeka kuramba.
