Indlela yokwelula impilo yesevisi yomshini wokubumba umjovo

Ipulasitiki izingxenye zomshini wokubumba umjovo, lapha kubhekiselwa ku: isikulufu, ncibilikisa umphongolo, ikhanda lenjoloba, indandatho yerabha, i-rubber gasket.

Lapho i- umjovo udini umshini uyasebenza, izingxenye ezenziwe ngepulasitiki zifana namasondo emoto. Inqobo nje uma ziqalisiwe, bazocindezelwa, umthelela, ukungqubuzana, bese ukhama. Okwesondo elifanayo, ukushayela emgwaqeni oyisicaba futhi ukusebenza ngomshayeli onekhono ngokuvamile kungandisa isikhathi sokusebenza kwesondo.

Futhi lapho ushayela emigwaqweni engalingani enesihlabathi esiningi namatshe, okuhambisana nezenzo zokubhuleka eziphuthumayo njalo, iphethini endaweni yesondo ipholishwa ngokushesha futhi ichithwe.

Ngakho-ke, ukuqinisekisa ukuthi umshini wokubumba umjovo uhlala usesimweni esihle, kuyadingeka ukucacisa ukusebenza komshini wokubumba umjovo osetshenzisiwe, baqonde ukusebenza kanye nekhwalithi ye izinto zepulasitiki esetshenzisiwe, kanye nokuqinisa ukuphathwa kokusetshenziswa komshini wokubumba umjovo ukunciphisa amazinga okuhluleka, ukunciphisa izindleko zokunakekela, futhi andise Inhloso ye impilo yesevisi.

Lapho umshini wokubumba umjovo usebenza, izingxenye ezenziwe ngepulasitiki zifana namasondo emoto. Inqobo nje uma ziqalisiwe, bazocindezelwa, umthelela, ukungqubuzana, bese ukhama. Okwesondo elifanayo, ukushayela emgwaqeni oyisicaba futhi ukusebenza ngomshayeli onekhono ngokuvamile kungandisa isikhathi sokusebenza kwesondo.

Futhi lapho ushayela emigwaqweni engalingani enesihlabathi esiningi namatshe, okuhambisana nezenzo zokubhuleka eziphuthumayo njalo, iphethini endaweni yesondo ipholishwa ngokushesha futhi ichithwe.Ngakho-ke, ukuqinisekisa ukuthi umshini wokubumba umjovo uhlala ungaphakathi isimo esihle, kuyadingeka ukucacisa ukusebenza komshini wokubumba umjovo osetshenzisiwe, qonda ukusebenza kanye nekhwalithi yezinto zepulasitiki ezisetshenzisiwe, kanye nokuqinisa ukuphathwa kokusetshenziswa komshini wokubumba umjovo ukunciphisa amazinga okuhluleka, ukunciphisa izindleko zokunakekela, futhi andise Inhloso yempilo yesevisi.

Sengisho nje, izici ezilandelayo zithinta impilo yesevisi ye-plasticizing system yomshini wokubumba umjovo:

Okokuqala, umphumela wokugqokwa kwemishini:

Amanye amapulasitiki ashintshiwe anezelwa ngamaminerali, ingilazi fiber, i-metal powder, njll. Ukuba khona kwalezi zinto kuzodala ukuguga komshini ofanayo kusikulufu, izingxenye ezintathu ezincane kanye nomgqomo oncibilikayo ngesikhathi se-plasticization kanye nokucubungula umjovo. Isendlalelo esine-nitrided kanye nesendlalelo esifakwe nge-chromium singapholishwa sisuke. Ngemuva kokulimala, igebe phakathi kwesikulufu kanye nomgqomo wokuncibilika liyakhula, okunciphisa umphumela we-plasticizing, kwandisa ukuvuza komjovo, kunciphisa ukusebenza kahle komjovo, futhi yehlisa ukunemba kokucubungula.

Ngakho-ke, ukuze kuncishiswe ukuguga nokunweba impilo yesevisi yezingxenye zepulasitiki, izinga lokushisa kufanele lenyuswe ngokufanelekile ngesikhathi sokucubungula futhi isivinini sesikulufa kufanele sincishiswe. Ukusetshenziswa kwe-chrome plating noma izixazululo ze-bimetallic kungavimbela ngempumelelo ukuhuzuka.Okwesibili, ukukhathala kwemishini kanye nomsebenzi ogcwele kakhulu:

Abalungisi bavamise ukusetha umsebenzi wezinga lokushisa eliphansi futhi bajwayele ukusetha umsebenzi onesivinini esikhulu nonengcindezi ephezulu., okwehlisa kancane kancane ukusebenza kwezingxenye zepulasitiki. Ngokwesibonelo, lapho ucubungula i-PC namapulasitiki e-PA, lapho izinga lokushisa lingahlangabezani nezidingo, i-viscosity yepulasitiki inkulu kakhulu. Uma isenzo se-sol siphoqelelwa ngalesi sikhathi, ukucindezela kwe-sol kanye ne-torque ye-sol kumele kwandiswe, ngaleyo ndlela kwandisa ukukhathala kokucindezeleka kwesikulufu. Ngesikhathi esifanayo, ngoba i-viscosity yokuncibilika kwepulasitiki iphezulu kakhulu ngalesi sikhathi, ingcindezi yomjovo kanye nesivinini somjovo kumele kunyuswe ekubumbeni umjovo, okwandisa umthelela kanye nomthwalo wezingxenye ezintathu ezincane, futhi isheshisa ukuguga kwabo nokwephuka kwengcindezi.

Okwesithathu, izici zomuntu (okuhlanganisa amaphutha okusebenza noma imisebenzi engekho emthethweni, njll.):

1). Lapho ukungcola kwensimbi kuhlanganiswa epulasitiki bese kufakwa emgqonyeni wokuncibilika ndawonye, ngenxa yomphumela we-extrusion, imiphetho yesikulufu, imifantu, izindandatho zenjoloba, ama-rubber gaskets we-screw azogqokwa ngamazinga ahlukene, okuzokwenza ukuthi inqubo yokubumba umjovo ingazinzi futhi ibe lula Khiqiza amabala amnyama nemicu emnyama;

2), engeza ipulasitiki engalungile, engeza ipulasitiki yokushisa okuphezulu emgqonyeni wokuncibilika obekwe ekushiseni okuphansi, okuholela ku-torque eyeqile yesikulufu ngesikhathi se-sol, kubangela ukukhathala kokucindezeleka kwesikulufu;

3) Isiqalo esibandayo siwuhlobo lwepsychology ekhathazayo kanye nesimo sengqondo sokungabi nasibopho sokuziphendulela. Lapho izinga lokushisa le-sol cylinder lingafinyelelanga izinga lokushisa elidingekayo noma lisanda kufinyelela, impahla esele emgqonyeni imunca ukushisa eringini yokushisa ukuze izinga lokushisa libe phezulu, kuyilapho izinga lokushisa longqimba lwangaphakathi lisephansi kakhulu. Ngakho-ke, ngesikhathi sokuqala okubandayo Itorque yesikulufu inkulu kakhulu, kubangela ukukhathala kwengcindezi kusikulufa. Ezimweni ezimbi kakhulu, isikulufu sizosonteka ngokushesha, futhi ikhanda lenjoloba nendandatho yerabha kuzosonteka.

Ukungcola okuningi kwensimbi okungena ku-sol cylinder kulethwa ngezinto ezichotshoziwe. Ngakho-ke, ukuphuka kwe-blade ye-crusher kufanele kuhlolwe njalo, futhi i-blade kufanele ishintshwe ngokushesha uma kutholakala ukuthi igqokile.

Ngokolunye uhlangothi, hlola futhi uhlanze omazibuthe ku-hopper engenalutho njalo. Lapho izinsalela zensimbi ezikhangisiwe eduze kukazibuthe ziyagcwala, amandla okukhangisa ezinsalela zensimbi ongqimbeni olungaphandle azoba buthakathaka. Noma iheha, izogezwa kalula yipulasitiki egelezayo eqhubekayo futhi ifake isilinda se-sol ndawonye.

Okwesine, hlanganisa kahle, lungisa iphutha bese ushintsha izingxenye:

Lesi sici futhi sibaluleke kakhulu. Uma umhlangano we-sol barrel ungaqinile ngokwanele, isikulufu sizothinta umphongolo we-sol lapho i-sol noma i-glue ijovwe, okwenza isikulufu noma umgqomo wesol uguge. Ngakho-ke, isimo sobuchwepheshe bemishini kufanele sihlolwe njalo, futhi kufanele kuqashelwe isenzakalo esingavamile sezingxenye zenqubo.Okwesihlanu, umonakalo odalwe wumsebenzi ongafanele:

1) Ukusetshenziswa isikhathi eside kwe-high back pressure sol kungasheshisa ukuguga kwezingxenye ezintathu zepulasitiki ezincane. Lesi simo ngokuvamile sivela lapho kusetshenziswa i-toner. Njengoba i-toner kunzima ukuyihlakaza, indlela yokwandisa ingcindezi yangemuva iyamukelwa.

2) Okwamapulasitiki ane-viscosity ephezulu, I-sol esheshayo isetshenziswa lapho i-sol isetshenziselwa ukubangela ukukhathala kokucindezeleka kwesikulufu;

3) Okwamapulasitiki asezingeni eliphezulu, ikakhulukazi ingilazi fiber-added plastic, indlela ye-sol enesivinini esiphezulu akufanele isetshenziswe.

Okwesithupha, ukugqwala kwamakhemikhali:

Insimbi egqwalile iyinsimbi. Amapulasitiki e-corrosive avamile ahlanganisa: amapulasitiki avimbela amalangabi, amapulasitiki ane-asidi, Amapulasitiki e-PVC, njll. Ngemva kwesikulufa, umphongolo oncibilikayo futhi i-flange igqwalile, eminye imigodi yakheka phezu, futhi ubuso bumaholoholo, okwenza ukumelana nokugeleza kokuncibilika lapho umshini wokubumba umjovo usebenza.

Ezinye izinto kulula ukunamathela phezulu, kubangela ukubola kanye ne-carbonization. Ukugqwala okukhulu kuzonyusa igebe phakathi kwesikulufu kanye nomgqomo oncibilikayo, ukwandisa ukuvuza, futhi unciphise ukusebenza kahle komjovo.

Kungakhathaliseki ukuthi ipulasitiki elibamba ilangabi noma iglue ene-asidi, i ipulasitiki izobolisa igesi ene-asidi uma icutshungulwa ezingeni lokushisa eliphezulu, futhi ukuncibilika kwepulasitiki kulula ukuthi kufakwe i-carbonized futhi kunamathele ensimbi. Ngakho-ke, Ngakolunye uhlangothi, izingxenye ezenziwe ngepulasitiki kufanele zenziwe ngensimbi engagqwali noma i-surface chromium plating; Ngokolunye uhlangothi, ingcindezi ephansi emuva, izinga lokushisa eliphansi kanye nezinqubo eziphansi zokugunda kufanele zisetshenziswe ngangokunokwenzeka ekukhiqizeni nasekucubungulweni ukuze kuncishiswe ukuwohloka kwepulasitiki.;

Esicini sesithathu, ngenxa yokuzwela okushisayo kwamapulasitiki angenhla, izinga lokushisa eliphezulu kakhulu noma isikhathi eside sokushisa.kulula ukubola, nciphisa futhi carbonize amapulasitiki. Ngakho-ke, inqubo yokukhiqiza kufanele igweme futhi inciphise ukuvala okwenziwayo. Uma udinga ukumisa umshini, kufanele wehlise izinga lokushisa kuqala, vala isango lezinto ezibonakalayo.Futhi ngemva kokuncibilika kwe-sol tube sekuphelile, shintshela ku-PP noma i-PS ukuze uhlanze ishubhu ye-sol ngaphambi kokumisa umshini.

Uma unemibuzo ku imboni yepulasitiki,plz zizwe ukhululekile ukubuza ithimba le-FLYSE,sizokunikeza isevisi engcono kakhulu!
