Nkhani

Pakuumba jekeseni wa nayiloni wodzazidwa ndi galasi, yambani ndi giredi yeniyeni ya PA ndi zomwe zili mugalasi. Nanhaiya amalemba zomangira zozimitsidwa ndi kupsya mtima za 38CrMoAlA zamapulasitiki olimba okhala ndi magalasi ofikira 30%, kuphatikiza PA-GF. Masamba ake omwe amapangidwa amafotokozanso za nitriding ndi nickel-tungsten alloy reinforcement for wear-prone screw screw ndi mbiya. Sankhani geometry ndi dongosolo la pamwamba motsutsana ndi ntchito yeniyeni, kenako yang'anani mbiya ya mbiya ndi nsonga yopukutira kapena fufuzani mphete musanavomere cholowa. Lamulo langa kumbali ya fakitale ndi losavuta: kuuma kwa mtengo sikupulumutsa geometry yolakwika, ndipo phula latsopano silipulumutsa kutsogolo kutsogolo. Ikani mawonekedwe onse atatu pachithunzicho ndi machitidwe onse atatu mu dongosolo la mayeso.

Sankhani zomangira jekeseni wosinthika kapena wadzidzidzi ngati poyambira zida za crystalline kapena semi-crystalline zomwe zimapindula ndi kukanikizana kofulumira ndi kusungunuka. Nanhaiya adalemba PE, PP, PA, POM ndi PTFE. Chigawo chake chosinthira mutant chimakhala pafupifupi 5% mpaka 15% ya kutalika konse kwa screw. Sankhani zomangira pang'onopang'ono ngati poyambira zida za amorphous kapena zosamva kutentha zomwe zimafunikira kusintha kosavuta. Nanhaiya amalemba PVC, PS, PC, PSU ndi ABS. Gawo lake loponderezedwa pang'onopang'ono limakhala ndi 40% mpaka 60% ya kutalika konse, ndipo pafupifupi 50% amafotokozedwa ngati wamba. Tsimikizirani kusankha kulikonse ndi giredi yeniyeni, chodzaza, chinyezi, kugwiritsa ntchito kuwombera, nthawi yochira, chikhalidwe chosungunuka ndi kuvomereza kwagawo loumbidwa.

Tchulani spika imodzi yothamanga kwambiri ya PE kapena PP yokhala ndi zinthu zenizeni, zotulutsa zomwe zingagulitsidwe, zogulitsa ndi kufa, kuthamanga kwapamwamba, zenera losungunuka, kupanikizika, ntchito yamoto ndi gearbox, kuziziritsa, malo ovala ndi njira yolandirira. Osagula kuchokera m'mimba mwake ndi ma rpm okha. Nanhaiya imasindikiza mitundu isanu ndi inayi yokhala ndi sikelo imodzi kuchokera ku NHY20 mpaka NHY150, yokhala ndi zotulutsa kuchokera ku 3 mpaka 1,300 kg / h ndipo liwiro limachokera ku 10 mpaka 150 rpm kudutsa banja lonse. Chida chake chothamanga kwambiri cha PE ndi PP chimagwiritsa ntchito jiyomethri yokonzedwa bwino, bokosi la giya lamphamvu kwambiri, migolo yapadera yamalo odyetsera komanso kapangidwe ka aloyi wosamva kuvala. Sinthani cholinga chilichonse cha polojekiti kukhala malo oyeserera okhazikika pogwiritsa ntchito resin, kufa, zenera labwino komanso malire oyezera magetsi.

Kuti mutchule sikona imodzi yosamva kuvala, tumizani utomoni weniweni ndi giredi, chodzaza kapena ulusi ndi kuchuluka kwake, zomwe zidabwezerezedwanso, kuipitsidwa, mawonekedwe a chakudya, chinyezi, mawonekedwe a mayeso a MFR kapena MVR, zomwe zimafunikira, kuthamanga kwa screw, kuchuluka kwa injini, kusungunula, kutentha, maola ogwirira ntchito ndi mapu omwe akuvalira. Ndiye kusankha pamwamba ndi kuwonongeka malo. Nanhaiya imapereka 38CrMoAlA, SACM645, 42CrMo ndi magawo achitsulo opangira, okhala ndi nitriding yakuya ya ion, chitetezo cha PTA pamwamba pa ndege ndi mbali, kuphatikiza tungsten carbide ndi njira zopangira faifi tambala. Zowononga zomwe zikufunidwa ziyenera kufufuzidwa ndi mbiya yokwerera, chifukwa malo olimba atsopano sangathe kukonza chibowo chokulirapo kapena cholakwika.

Kuti mugule bokosi la pulasitiki la extruder gearbox, tchulani mphamvu yamagalimoto ndi liwiro lovotera, kuchuluka kwa liwiro lothamanga, ntchito yopitilira ndi nsonga ya torque, kuchuluka kwa mazenera ndi kuzungulira, zinthu ndi zotulutsa, maola ogwiritsira ntchito, malo olowera ndi kutulutsa shaft, malo okwera, kukankhira, kuthirira, kuziziritsa ndi kuyesa kuvomereza. Mphamvu zamagalimoto zokha sizomwe zili mu gearbox. Mizere iwiri yokhala ndi mota imodzi imatha kuyika torque yosiyana, kutentha, kugwedezeka, kulunzanitsa ndi ntchito zonyamula. Chojambula chosainidwa chiyenera kuzindikira shaft ya mbali ya motor ndi screw-side shaft, kuthamanga kwake, mayendedwe ozungulira, chiŵerengero, ma datum oyikira ndi kulumikizana kulikonse kofunikira pakuyika.

Kuti mugule flange ya extruder mbiya, tumizani chojambula chowongolera chomwe chimazindikiritsa bore, m'mimba mwake, makulidwe, kaundula, kaundula wa bawuti, nkhope yosindikiza, zinthu, chithandizo chapamwamba ndi magawo okwerera. Onjezani maziko enieni a kutentha ndi kupanikizika, chitsanzo cha extruder kapena die-head, kuchuluka ndi zofunikira zoyendera. Osayitanitsa makina osinthika kuchokera ku mawu oti "ANSI," "DIN," "JIS" kapena "PN16" okha. Maumboni amenewo atha kutanthauzira chitoliro cha chitoliro chokhazikika pokhapokha chikhazikitso chonse ndi maziko a ntchito anenedwa. Kulumikizana kwa extruder nthawi zambiri kumafunika kujambula kwake, ngakhale mbali imodzi ikatsatira mawonekedwe odziwika a flange.
