Momwe mungakulitsire moyo wautumiki wamakina omangira jekeseni

Zapulasitiki zigawo za makina opangira jekeseni, apa akunena za: screw, Sungunulani mbiya, mutu wa rabala, mphete ya mphira, mphira gasket.

Pamene a makina jekeseni akamaumba ikugwira ntchito, zigawo za pulasitiki zili ngati magudumu a galimoto. Malingana ngati ayambika, adzapanikizidwa, zotsatira, kukangana, ndi kufinya. Kwa tayala lomwelo, kuyendetsa galimoto mumsewu wathyathyathya ndi kuyendetsedwa ndi dalaivala waluso nthawi zambiri kumatha kutalikitsa moyo wa tayalalo.

Ndipo poyendetsa m'misewu yosagwirizana ndi mchenga ndi miyala yambiri, kuphatikizira ndi zochitika pafupipafupi zadzidzidzi mabuleki, chitsanzo pamwamba pa matayala mofulumira opukutidwa ndi kuchotsedwa.

Chifukwa chake, kuonetsetsa kuti makina opangira jekeseni amakhala bwino nthawi zonse, m'pofunika kufotokoza bwino ntchito ya jekeseni akamaumba makina ntchito, kumvetsetsa magwiridwe antchito ndi mtundu wa zipangizo zapulasitiki ntchito, ndi kulimbikitsa kasamalidwe ka kugwiritsa ntchito makina opangira jekeseni kuti achepetse kulephera, kuchepetsa ndalama zosamalira, ndi kukulitsa Cholinga cha moyo wautumiki.

Pamene makina opangira jekeseni akugwira ntchito, zigawo za pulasitiki zili ngati magudumu a galimoto. Malingana ngati ayambika, adzapanikizidwa, zotsatira, kukangana, ndi kufinya. Kwa tayala lomwelo, kuyendetsa galimoto mumsewu wathyathyathya ndi kuyendetsedwa ndi dalaivala waluso nthawi zambiri kumatha kutalikitsa moyo wa tayalalo.

Ndipo poyendetsa m'misewu yosagwirizana ndi mchenga ndi miyala yambiri, kuphatikizira ndi zochitika pafupipafupi zadzidzidzi mabuleki, chitsanzo pamwamba pa matayala mofulumira opukutidwa ndi scraped.Chifukwa chake, kuonetsetsa kuti makina opangira jekeseni amakhala nthawi zonse zabwino, m'pofunika kufotokoza bwino ntchito ya jekeseni akamaumba makina ntchito, kumvetsetsa magwiridwe antchito ndi mtundu wa zida zapulasitiki zomwe zimagwiritsidwa ntchito, ndi kulimbikitsa kasamalidwe ka kugwiritsa ntchito makina opangira jekeseni kuti achepetse kulephera, kuchepetsa ndalama zosamalira, ndikukulitsa Cholinga cha moyo wautumiki.

Nthawi zambiri, zotsatirazi zimakhudza moyo wautumiki wa dongosolo la plasticizing la makina omangira jekeseni:

Choyamba, zotsatira za makina ovala:

Mapulasitiki ena osinthidwa amawonjezeredwa ndi mchere, Fiber, ufa wachitsulo, etc.. Kukhalapo kwa zinthu izi kumapangitsa kuvala kwa makina ofananirako pa screw, zigawo zitatu zazing'ono ndi mbiya Sungunulani pa plasticization ndi jekeseni processing. Chosanjikiza cha nitrided ndi chromium-chokutidwa ndi chromium zitha kupukutidwa. Pambuyo abrasion, kusiyana pakati pa wononga ndi mbiya yosungunuka kumawonjezeka, zomwe zimachepetsa mphamvu ya plasticizing, kumawonjezera kutayikira kwa jekeseni, amachepetsa jekeseni dzuwa, ndipo amachepetsa kulondola kwa processing.

Chifukwa chake, kuti muchepetse kuvala ndikukulitsa moyo utumiki wa zigawo plasticized, kutentha kuyenera kuchulukitsidwa moyenerera panthawi yokonza ndipo liwiro la screw liyenera kuchepetsedwa. Kugwiritsa ntchito chrome plating kapena bimetallic solutions kumatha kuteteza bwino abrasion.Chachiwiri, kutopa kwamakina ndi ntchito yolemetsa:

Osinthawo amakhala ndi chizolowezi chogwira ntchito yotentha kwambiri ndipo amakhala ndi chizolowezi chogwira ntchito yothamanga kwambiri komanso yothamanga kwambiri., zomwe zimawononga pang'onopang'ono ntchito za zigawo zapulasitiki. Mwachitsanzo, pokonza PC ndi PA mapulasitiki, pamene kutentha sikukwaniritsa zofunikira, kukhuthala kwa pulasitiki ndi kwakukulu kwambiri. Ngati ntchito ya sol ikukakamizidwa panthawiyi, mphamvu ya sol ndi torque ya sol iyenera kuwonjezeka, motero kumawonjezera kutopa kwanthawi yayitali kwa screw. Nthawi yomweyo, chifukwa mamasukidwe akayendedwe a pulasitiki kusungunula kwambiri pa nthawi ino, kuthamanga kwa jakisoni ndi liwiro la jakisoni ziyenera kuonjezedwa pakuumba jekeseni, zomwe zimawonjezera mphamvu ndi katundu wa magawo atatu ang'onoang'ono, ndi kufulumizitsa kuvala kwawo ndi kusweka kwa nkhawa.

Chachitatu, zinthu zaumunthu (kuphatikizirapo zolakwika kapena ntchito zosaloledwa, etc.):

1). Pamene zonyansa zachitsulo zimasakanizidwa mu pulasitiki ndikulowetsa mbiya yosungunuka pamodzi, chifukwa cha extrusion effect, m'mphepete mwa screw, mapanga, mphete za mphira, ma gaskets a mphira a wononga adzavala mosiyanasiyana, zomwe zidzapangitse njira yopangira jekeseni kukhala yosakhazikika komanso yosavuta Kupanga mawanga akuda ndi mikwingwirima yakuda;

2), onjezerani pulasitiki yolakwika, onjezerani pulasitiki yotentha kwambiri ku mbiya yosungunula yoyikidwa pa kutentha kochepa, kumabweretsa kuchulukirachulukira kwa screw panthawi ya sol, kuchititsa kutopa kwa screw;

3) Kuyamba kozizira ndi mtundu wamalingaliro oda nkhawa komanso malingaliro osasamala pantchito. Pamene kutentha kwa sol cylinder sikunafikire kutentha komwe kumafunikira kapena kwangofika kumene, zinthu zotsalira mu mbiya zimatenga kutentha kwa mphete yotenthetsera kuti kutentha kukhale kokwera, pamene kutentha kwa wosanjikiza wamkati akadali otsika kwambiri. Chifukwa chake, poyambira kuzizira The screw torque ndi yayikulu kwambiri, kuchititsa kutopa kwachisoni pa screw. Mu milandu kwambiri, screw idzapindika mofulumira, ndipo mutu wa rabala ndi mphete ya rabala zidzapindika.

Zonyansa zambiri zachitsulo zomwe zimalowa mu sol cylinder zimabweretsedwa ndi zinthu zowonongeka. Chifukwa chake, kusweka kwa tsamba la crusher kuyenera kuyang'aniridwa pafupipafupi, ndipo tsambalo liyenera kusinthidwa nthawi yomweyo ngati lipezeka kuti lavala.

Mbali inayi, yang'anani ndikuyeretsa maginito mu hopper yopanda kanthu pafupipafupi. Pamene zitsulo nyenyeswa adsorbed padziko maginito ali zikhuta, mphamvu yotsatsira zitsulo zachitsulo pamtunda wakunja zidzafooka. Ngakhale atakopeka, imatsukidwa mosavuta ndi pulasitiki yoyenda mosalekeza ndikulowa mu sol cylinder pamodzi.

Chachinayi, kusonkhanitsa molondola, sinthani ndikusintha magawo:

Mbali imeneyi ndi yofunika kwambiri. Ngati gulu la sol mbiya silothina mokwanira, screw idzakhudza mbiya ya sol pamene sol kapena guluu jekeseni, kuchititsa kuti screw kapena mbiya ya sol iwonongeke. Chifukwa chake, luso la zipangizo ayenera kufufuzidwa nthawi zonse, ndipo chidwi chiyenera kuperekedwa ku zochitika zachilendo za ziwalo zomwe zili mu ndondomekoyi.Chachisanu, kuwonongeka chifukwa cha ntchito yosayenera:

1) Kugwiritsa ntchito nthawi yayitali kwa high back pressure sol kumatha kufulumizitsa kuvala kwa magawo atatu ang'onoang'ono apulasitiki. Izi zimachitika nthawi zambiri pakagwiritsidwa ntchito toner. Popeza tona ndizovuta kumwazikana, njira yowonjezera kupanikizika kwa msana imatengedwa.

2) Kwa mapulasitiki apamwamba kwambiri, Fast sol imagwiritsidwa ntchito ngati sol imagwiritsidwa ntchito kuyambitsa kutopa kwa screw;

3) Kwa mapulasitiki otentha kwambiri, makamaka mapulasitiki owonjezera magalasi, njira yothamanga kwambiri sayenera kugwiritsidwa ntchito.

Chachisanu ndi chimodzi, mankhwala dzimbiri:

Chitsulo cha dzimbiri ndi chitsulo. Mapulasitiki owononga wamba akuphatikizapo: mapulasitiki oletsa moto, mapulasitiki acidic, PVC mapulasitiki, etc.. Pambuyo pa screw, Sungunulani mbiya ndipo flange ndi dzimbiri, maenje ena amapangidwa pamwamba, ndipo pamwamba pake ndi yovuta, zomwe zimapanga kukana kothamanga kwa kusungunuka pamene makina opangira jekeseni amagwira ntchito.

Zida zina ndizosavuta kumamatira pamwamba, kuchititsa kuwonongeka ndi carbonization. Kuwonongeka kwakukulu kumawonjezera kusiyana pakati pa wononga ndi mbiya yosungunuka, onjezerani kutayikira, ndi kuchepetsa mphamvu ya jekeseni.

Kaya ndi pulasitiki wosagwira moto kapena guluu wa asidi, a pulasitiki idzawola mpweya wa asidi ikakonzedwa pa kutentha kwakukulu, ndipo kusungunuka kwa pulasitiki kumakhala kosavuta kukhala carbonized ndi kumamatira kuzitsulo. Chifukwa chake, mbali inayi, zigawo zapulasitiki ziyenera kupangidwa ndi chitsulo chosapanga dzimbiri kapena pamwamba pa chromium plating; Pambuyo pa kukula kwake, kutsika kwa msana, kutentha kwapansi ndi njira zochepetsera zometa ubweya ziyenera kugwiritsidwa ntchito momwe zingathere popanga ndi kukonza kuti muchepetse kuwonongeka kwa pulasitiki.;

M'mbali yachitatu, chifukwa cha kumva kutentha kwa mapulasitiki omwe ali pamwambawa, kutentha kwambiri kapena nthawi yotentha kwambiri.ndizosavuta kuwola, kuwononga ndi carbonize mapulasitiki. Chifukwa chake, kupanga kuyenera kupewedwa ndikuchepetsa kuzimitsa kochita kupanga. Ngati muyenera kuyimitsa makina, muyenera kuchepetsa kutentha poyamba, Tsekani chipata cha zinthu. Ndipo kusungunuka mu chubu cha sol kutha, sinthani ku PP kapena PS kuti muyeretse chubu cha Sol musanayambe kuyimitsa makina.

Ngati muli ndi mafunso pa mafakitale apulasitiki,plz omasuka kufunsa timu ya FLYSE,tidzakupatsani utumiki wabwino kwambiri!
