I-extruder iyisisetshenziswa esibalulekile sokucubungula ukubumba kwepulasitiki kanye ne-pelletizing. Ukusetshenziswa kwansuku zonke kwe-extruder kunganikeza ukudlala okuphelele ekusebenzeni kahle komshini futhi kugcine isimo esihle sokusebenza. Kufanele igcinwe ngokucophelela ngaphandle kokuyekethisa ukuze inwebe impilo yesevisi yomshini. Ukwehluleka okuyinhloko kwe-extruder umsindo ongavamile nokudlidliza okungavamile okubangelwa ukuguga okungavamile, ukuguga noma ukulimala kwezingxenye zokudlulisela, kanye nokugcotshwa okunganele.

Amaphutha ajwayelekile we-plastic extruder:
1. Umsingathi wamanje awuzinzile
Izizathu zokukhiqiza:
● Ukudla ngendlela engalingani.
● I-motor bearing eyinhloko ilimele noma ayigcotshisiwe kahle.
● Ingxenye ethile ye-heater iyahluleka futhi ayishisi.
● Iphedi yokulungisa isikulufu ayilungile, noma isigaba sibi, futhi izingxenye ziyaphazamisa.

Indlela:
● Hlola i-feed bese uxazulula inkinga.
● Hlaziya injini eyinhloko bese ushintsha ama-bearings uma kunesidingo.
● Hlola ukuthi ihitha ngayinye iyasebenza yini, bese uyishintsha uma kudingeka.
● Hlola iphedi yokulungisa bese ukhipha isikulufu ukuze uhlole ukuthi akukho yini ukuphazamiseka kusikulufu.

2. Injini eyinhloko ayikwazi ukuqala
Isizathu:
● Kunephutha enqubweni yokushayela.
● Kunenkinga ngentambo enkulu yenjini, noma ngabe i-fuse iyasha.
● Umshini oxhumanisayo ohlobene nezinjini zokuqala ziyasebenza
Indlela:
● Hlola inqubo bese ushayela futhi ngokulandelana okufanele.
● Hlola isekethe yemoto yokuqala.
● Hlola ukuthi iphampu kawoyela wokugcoba iqalisiwe futhi uhlole isimo sedivayisi exhumeneyo esihlobene nenjini eyinhloko. Iphampu kawoyela ayikwazi ukuvula, futhi injini ayikwazi ukuvuleka.
● I-induction current ye-inverter ayizange ikhishwe. Vala ugesi oyinhloko bese ulinda imizuzu emi-5 ngaphambi kokuqala.
● Hlola ukuthi inkinobho yesimo esiphuthumayo isethwe kabusha yini.

3.Ikhanda lomshini alibushelelezi noma livinjiwe
Isizathu:
● Ingxenye ethile ye-heater ayisebenzi, futhi ukufakwa kwepulasitiki kwempahla kubi.
● Izinga lokushisa lokusebenza lisethwe liphansi kakhulu, noma ukusabalalisa kwesisindo samangqamuzana epulasitiki kubanzi futhi akuzinzile.
● Kungase kube nezinto zangaphandle okungelula ukuncibilika.
Indlela:
● Hlola i-heater bese uyishintsha uma kunesidingo.
● Qinisekisa izinga lokushisa elimisiwe lesigaba ngasinye, xoxisana nochwepheshe uma kudingekile, futhi wandise inani lesethi lokushisa.
● Hlanza futhi uhlole uhlelo lwe-extrusion kanye nekhanda lomshini.

4. Amandla okuqala okuqala aphezulu kakhulu
Isizathu:
● Isikhathi sokushisa asanele, futhi i-torque yanele.
● Ingxenye ethile yehitha ayisebenzi.
Indlela:
● Ngaphambi kokushayela, sebenzisa isondo lesandla. Uma kungelula, nweba isikhathi sokushisisa noma uhlole ukuthi ingxenye ngayinye ye-heater isebenza nsuku zonke.

5. Injini eyinhloko yenza umsindo ongajwayelekile
Isizathu:
● I-motor bear enkulu ilimele.
● I-SCR ethile kumjikelezo we-SCR rectifier yenjini eyinhloko yonakele.
Indlela:
● Faka esikhundleni senjini eyinhloko.
● Hlola isekethe ye-thyristor rectifier, bese ubuyisela isici se-thyristor uma kunesidingo.

6.Ukukhuphuka kwezinga lokushisa okuthwala injini kuphezulu kakhulu
Isizathu:
● I-lubrication ye-aber engalungile.
● I-bearing igugile kakhulu.
Indlela:
● Hlola bese wengeza okokugcoba. Hlola ama-motor bearings bese uwashintsha uma kunesidingo.

7.Ingcindezi yekhanda ayizinzile
Isizathu:
● Ijubane lokujikeleza lenjini eyinhloko alilingani.
● Ijubane lenjini yokudla liyaguquguquka, futhi inani lokudla liyashintshashintsha.
Indlela:
● Hlola isistimu yokulawula imoto emaphakathi namabheringi.
● Hlola injini yesistimu yokudla kanye nesistimu yokulawula.

8. Ukucindezela kwamafutha okugcoba okuphansi
Isizathu:
● Inani lokusetha ingcindezi yevalvu elawula umfutho wesistimu kawoyela wokugcoba liphansi kakhulu.
● Iphampu kawoyela inephutha, noma ipayipi lokumunca uwoyela livalekile.
Indlela:
● Hlola futhi ulungise i-valve elawula umfutho wesistimu kawoyela wokugcoba.
● Hlola iphampu kawoyela kanye nepayipi lokumunca.

Ukuze ugweme ukwehluleka kanye nokugcinwa kwansuku zonke, ukugcinwa, nokulungiswa kabusha ngokuhambisana ngokuqinile nezidingo, kuyadingeka futhi ukunaka ukugqokwa kwesikulufu se-extruder.
Ukuguga okuvamile kwesikulufu kanye nomgqomo we-extruder yepulasitiki kwenzeka ikakhulukazi endaweni yokudla kanye nendawo yokulinganisa. Isizathu esihamba phambili sokuguga ukungqubuzana okomile phakathi kwezinhlayiya ze-chip nendawo yensimbi; lapho i-chip ishisa futhi ithambile, iyancipha.

I-extruder yesikulufu esisodwa

Ukuguga okungavamile kwesikulufu nomgqomo kuzokwenzeka lapho ukukhiya isikulufu ngamafindo ayindandatho nezinto zangaphandle. Ifindo eliyindandatho lisho ukuthi into ejiyile ikhiya isikulufu. Uma i-screw extruder ingenayo idivayisi efanelekile yokuvikela, amandla okushayela anamandla angase asonte. Uma isikulufu sibhajwe, sizokhiqiza ukumelana okukhulu, okubangele umonakalo omkhulu ebusweni besikulufu kanye nemihuzuko enzima emgqonyeni.
Ukuklwebheka emgqonyeni kuyinselele ukuyilungisa. Umphongolo uklanyelwe ngokomthetho ukuqinisekisa ukuthi impilo yesevisi yinde kunaleyo yesikulufu. Ngokugqoka okujwayelekile komgqomo, ngokuvamile awulungiswa. Indlela yokuthuthukisa intambo yesikulufu ivame ukusetshenziselwa ukubuyisela igebe le-radial phakathi kwembobo engaphakathi yombhobho kanye nobubanzi obungaphandle besikulufu.

Isixazululo:
Ukulimala kwasendaweni kokulungisa intambo yesikulufu ngokufaka i-alloy ekhethekile evimbela ukuguga kanye ne-alloy emelana nokugqwala. Ngokuvamile, i-inert gas shielded welding, kanye ne-plasma argon iyashisela, futhi ubuchwepheshe bokufafaza ngensimbi bungasetshenziswa futhi ukulungisa. Okokuqala, gaya indawo engaphandle yesikulufu esigugile ekujuleni okungaba ngu-1.5mm, bese umboza isendlalelo sengxubevange sibe usayizi owanele ukuze uqinisekise ukuvunyelwa komshini owanele, futhi ekugcineni ugaye indilinga yangaphandle yesikulufu kanye nohlangothi lwesikulufu kuya kusayizi wangempela wosayizi wesikulufu.

Umsindo ongafanele
● Uma kwenzeka kusinciphisi, kungase kubangelwe ukuthwala umonakalo noma ukugcotshwa okunganele noma okubangelwa ukuguga kwegiya, ukufakwa okungafanele, nokulungiswa, noma ukungaxhunywa kahle kwensimbi. Ingakwazi ukuxazulula ngokushintsha ama-bearings, ukuthuthukisa ukuthambisa, ukufaka esikhundleni samagiya, noma ukulungisa izimo zokuxhuma amagiya.
● Uma umsindo uwumsindo wokuklwebha obukhali, cabanga ukuthi kungenzeka yini ikhanda le-shaft kanye nomkhono we-shaft shaft ukuklwebheka ngenxa yokuchezuka kombhobho. Ingaxazulula ngokulungisa umgqomo.
● Uma umgqomo ubanga umsindo, kungenzeka ukuthi kungenxa yokuthi isikulufu sigobile ukuze sishanele ibhore noma izinga lokushisa elibekiwe liphansi kakhulu, okubangela ukungqubuzana okukhulu kwezinhlayiya eziqinile. Ingacutshungulwa ngokuqondisa isikulufu noma ukwandisa izinga lokushisa elibekiwe.

Ukudlidliza okungavamile
Uma lokhu kwenzeka ku-reducer, kubangelwa ukugqoka kwama-bearings namagiya, okungaxazululwa ngokushintsha ama-bearings noma amagiya. Uma kwenzeka emgqonyeni, kungenxa yendaba eyinkimbinkimbi yangaphandle exutshwe ezintweni, futhi ukuhlanzeka kwezinto ezibonakalayo kudinga ukuhlolwa. Uma kunesidingo, faka idivayisi eqinile kazibuthe ku-hopper ukuze ukhangise amafayili ensimbi.

Ukuvinjwa kwe-annular endaweni yokufaka isikulufu
Lokhu kwehluleka kubangela ngokuyinhloko ukuphazamiseka kwamanzi okupholisa noma ukugeleza okunganele. Isistimu yokupholisa idinga ukuhlola, futhi ukugeleza nokucindezela kwamanzi okupholisa kufanele kuhambisane nezidingo ezicacisiwe. Kungenzeka futhi ukuthi ucezu olukhulu lwempahla egaywe kabusha endaweni eluhlaza luvimba i-inlet futhi ludinga ukuhlanza. Inlet.
Okungenhla ukuhlaziya ukwehluleka okujwayelekile kanye nezixazululo ze-plastic extruder. Bona ukuthi ufundile yini?
