1. Sefa ndi kuphatikiza nozzle
Zonyansa za pulasitiki zimatha kuchotsedwa ndi fyuluta ya mphuno yowonjezera, ndiko kuti, kusungunula ndi pulasitiki kudutsa mumsewu, womwe umapatulidwa m'malo opapatiza ndi choyikapo.Kuchepetsa ndi mipata kumeneku kumatha kuchotsa zonyansa ndikuwongolera kusakanikirana kwa mapulasitiki.Choncho, chosakanizira chokhazikika chingagwiritsidwe ntchito kukwaniritsa zotsatira zabwino zosakaniza.Zidazi zitha kukhazikitsidwa pakati pa silinda ya jakisoni ndi jekeseni kuti alekanitse ndikusakaniza guluu wosungunuka.Ambiri a iwo amapanga kusungunuka kumayenda kudzera muzitsulo zosapanga dzimbiri.
2. Kutopa
Mapulasitiki ena amafunikira kutulutsa mpweya mu silinda ya jakisoni pomanga jekeseni kuti mpweya utuluke.Nthawi zambiri, mipweya iyi ndi mpweya wokha, koma imatha kukhala madzi kapena mpweya wa molekyulu imodzi yotulutsidwa ndi kusungunuka.Ngati mpweya uwu sungathe kumasulidwa, udzapanikizidwa ndi guluu wosungunula ndikubweretsedwa mu nkhungu, yomwe idzakula ndi kupanga thovu mu mankhwala.Kutulutsa mpweya usanafike pamphuno kapena nkhungu, chepetsani kapena kuchepetsa kukula kwa muzu wa wononga kuti muchepetse kusungunuka kwa silinda ya jakisoni.
Apa, mpweya ukhoza kutulutsidwa m'mabowo kapena mabowo pa silinda ya jakisoni.Kenako, m'mimba mwake muzu wa screw umachulukitsidwa, ndipo guluu losungunuka lomwe limachotsedwa limagwiritsidwa ntchito pamphuno.Makina omangira jekeseni okhala ndi malowa amatchedwa makina opangira jekeseni wotulutsa mpweya.Pamwamba pa makina opangira jekeseni, payenera kukhala chowotchera chothandizira komanso chopopera utsi chabwino chochotsera mpweya womwe ungakhale wovulaza.
3. Chongani valavu
Ziribe kanthu mtundu wa screw yomwe imagwiritsidwa ntchito, nsonga yake nthawi zambiri imakhala ndi valve yoyimitsa.Pofuna kuteteza pulasitiki kuti isatuluke mumphuno, chipangizo chochepetsera (chingwe chotsitsimula) kapena mphuno yapadera idzayikidwanso.Pogwiritsa ntchito njira zoletsa kuchotsa mimba ndi kutsatsa, ziyenera kuyang'aniridwa pafupipafupi, chifukwa ndi gawo lofunikira la silinda yowombera.Pakadali pano, nozzle yamtundu wa switch sigwiritsidwa ntchito kwambiri, chifukwa ndiyosavuta kutulutsa pulasitiki ndikuwola mu zida.Pakalipano, mtundu uliwonse wa pulasitiki uli ndi mndandanda wa mitundu yoyenera ya ma nozzles owombera.
4. Kuthamanga kwa wononga
Kuthamanga kozungulira kwa wononga kumakhudza kwambiri kukhazikika kwa njira yopangira jekeseni komanso kutentha komwe kumagwira pa pulasitiki.Kuthamanga kozungulira kozungulira kumakwera kwambiri.Pamene wononga imazungulira pa liwiro lalikulu, kukangana (kumeta ubweya) mphamvu zimaperekedwa ku pulasitiki kumapangitsa kuti pulasitiki ikhale yabwino, komanso imawonjezera kutentha kwa kutentha kwasungunuka.Chifukwa cha kufunikira kwa liwiro la wononga pamwamba, kuthamanga kwa makina opangira jekeseni wamkulu kuyenera kukhala kochepa kuposa makina ang'onoang'ono omangira jekeseni, chifukwa kutentha kwa shear komwe kumapangidwa ndi wononga kwakukulu kumakhala kokwera kwambiri kuposa kwa makina opangira jekeseni. wononga yaying'ono pa liwiro lozungulira lomwelo.Chifukwa cha mapulasitiki osiyanasiyana, kuthamanga kwa screw rotation kumasiyananso.
5. Chiyerekezo cha plasticizing mphamvu
Kuti mudziwe ngati mtundu wa kupanga ukhoza kusungidwa pakupanga konse, njira yosavuta yokhudzana ndi kutulutsa ndi mphamvu ya plasticizing ingagwiritsidwe ntchito motere: T = (okwana jekeseni kuwomba gx3600) ÷ (plasticizing kuchuluka kwa jekeseni akamaumba makina kg / hx1000 ) t ndi nthawi yochepa yozungulira.Ngati mkombero nthawi nkhungu ndi m'munsi kuposa T, jekeseni akamaumba makina sangathe mokwanira plasticize pulasitiki kukwaniritsa yunifolomu Sungunulani mamasukidwe akayendedwe, kotero jekeseni akamaumba mbali zambiri kupatuka.Makamaka, pamene jekeseni akamaumba woonda-mipanda kapena mwatsatanetsatane kulolerana mankhwala, kuchuluka jekeseni ndi plasticizing kuchuluka ayenera zikugwirizana wina ndi mzake.
6. Kuwerengera nthawi yosunga komanso kufunika kwake
Monga mwachizolowezi, nthawi yokhalamo pulasitiki inayake pamakina ena opangira jekeseni iyenera kuwerengedwa.Makamaka pamene makina akuluakulu opangira jekeseni amagwiritsa ntchito jekeseni pang'ono, pulasitiki ndiyosavuta kuwola, yomwe siidziwika poyang'ana.Ngati nthawi yosungiramo ndi yochepa, pulasitiki sichidzapangidwa ndi pulasitiki mofanana;Chuma cha pulasitiki chidzawola ndi kuwonjezeka kwa nthawi yosungira.
Chifukwa chake, nthawi yosungira iyenera kukhala yofanana.Njira: kuwonetsetsa kuti pulasitiki yolowera mu makina opangira jekeseni imakhala yokhazikika, kukula kwake ndi mawonekedwe.Ngati pali vuto lililonse kapena kutayika m'zigawo za makina opangira jakisoni, lipoti ku dipatimenti yokonza.
7. Kutentha kwa nkhungu
Nthawi zonse fufuzani ngati makina opangira jekeseni akhazikitsidwa ndikugwiritsidwa ntchito pa kutentha komwe kumatchulidwa pa pepala lojambula.Izi ndi zofunika kwambiri.Chifukwa kutentha kudzakhudza mapeto a pamwamba ndi zokolola za jekeseni kuumbidwa mbali.Miyezo yonse yoyezedwa iyenera kulembedwa ndipo makina opangira jekeseni amawunikiridwa pa nthawi yodziwika.
