A. Uhlelo lokufudumala nokupholisa
Uhlelo lokushisa nokupholisa lwe-extruder lubhekisela kakhulu ekushiseni nasekupholiseni kwebhareli (kufaka phakathi i-molding die kanye ne-screw) ohlelweni lwe-extrusion plasticizing. Inhloso yokushisa noma ukupholisa ibhareli (ukwakha isikhunta kanye ne-screw) ukulawula izinga lokushisa lenqubo yezinto zokusetshenziswa ngesikhathi sokukhipha kanye nokufaka ipulasitiki bese ulikhawulela ebangeni elithile ukuqinisekisa ukukhiqizwa okuvamile kwemikhiqizo yepulasitiki eyenziwe yi- ipulasitiki extruder.
Ukushisa kwebhareli
Izindlela zokushisa zebhareli (ukwakha isikhunta) ku-extruder zifaka phakathi ukushisa okumelana, ukushisa okufakwa ngogesi kanye nokushisa kwe-heat carrier. Njengamanje, indlela yokushisa esetshenziswa kakhulu ukushisa okumelana.
1) Ukumelana nokushisa.
Indlela yokushisa ukumelana inesakhiwo esilula. Ngokuyinhloko ivumela ugesi ukuthi udlule ngocingo (intambo yokumelana) enokumelana okukhulu ukuze kukhiqizwe ukushisa futhi kuqondiswe emgqonyeni odinga ukufudunyezwa. I-heater yokumelana ne-aluminium sleeve ephonswe nge-aluminium ishubhu yensimbi, igcwalise ishubhu ngezinto zokuvimbela ezifana ne-magnesium oxide powder, bese iphonsa ishubhu yensimbi nge-aluminium alloy. Lolu hlobo lwe-heater yokumelana ne-aluminium sleeve ephonswe nge-magnesium oxide insulating powder eshubhu futhi ivalwe kahle, okuvimbela ukushiswa kwentambo yokumelana ngaphambi kwesikhathi futhi ihlala isikhathi eside. Indawo yokuxhumana phakathi kwe-sleeve ye-aluminium alloy kanye nendilinga yangaphandle yebharele inkulu. , ukusebenza okuhle kokudlulisa ukushisa.
2) Ukushisa kokufakwa kukagesi.
Idivayisi yokushisa yokungenisa kagesi. Lapho ibhereli isebenzisa ukushisa kokungenisa kagesi, kufakwa ikhoyili engxenyeni engaphandle yomgqomo, bese kufakwa ishidi lensimbi le-silicon eliqhuba ugesi elizungeze ikhoyili. Lapho ugesi udlula ku-khoyili, ishidi lensimbi le-silicon kanye nomgqomo kwakha isekethe elivaliwe le-magnetic. Ukushintshana kwe-magnetic flux induction kubangela ukuthi umgqomo ukhiqize ugesi, futhi umgqomo ukhiqiza ukushisa ngenxa yenani lawo elithile lokumelana. Umgqomo usebenzisa indlela yokushisa yokungenisa kagesi ukuze ushise ngokushesha, futhi izinto ezisetshenziselwa ukwakha i-inductor zisebenza isikhathi eside, kodwa izingxenye ezisetshenziswa ukwakha i-inductor ziyinkimbinkimbi kakhulu.
3) Ukushisa ngesithwali sokushisa.
Imishini yokushisa esebenzisa umhwamuko wamanzi noma uwoyela njengesithwali sokushisa idinga ukuthuthwa ngepayipi kanye nomthombo wokushisa (umthombo wokushisa webhoyila noma wokumelana) wesithwali sokushisa. Imishini iyinkimbinkimbi, iyabiza, futhi ukulawula izinga lokushisa kunzima, ngakho-ke iyasebenza kakhulu. Kodwa-ke, le ndlela yokushisa inokushisa okuthambile nokulinganayo, okufanele kakhulu ukufudumeza amapulasitiki azwela ukushisa.
Ukupholisa kwebhareli
Ukupholisa kwe isikulufu nomgqomo kwe-extruder, ukupholisa ingxenye ye-extruder efaka ipulasitiki, ukupholisa isihlalo se-hopper kanye nokupholisa isikulufu. Ukupholisa ingxenye ye-plastic ekhishwe emshinini. Ukupholisa ingxenye ye-plastic kuyindlela yokupholisa ukuvimbela izinga lokushisa lomshini ukuthi lingabi phezulu kakhulu ngesikhathi sokusebenza. Kunezindlela ezimbili zokupholisa: ukupholisa ngamanzi kanye nokupholisa umoya. Njengamanje, indlela esetshenziswa kakhulu ukupholisa umoya. Isebenzisa ifeni ukushaya ngqo izingxenye zebhereli ezidinga ukuphola, futhi umoya obandayo ususa ukushisa kwebhereli, ngaleyo ndlela kufezwe injongo yokupholisa ibhereli. Indlela yebhereli yokupholisa ifeni ilula, isakhiwo semishini silula, umthelela wokushisa emgqonyeni uncane, izindleko aziphezulu, futhi imisebenzi yokulungisa kanye nokukhiqiza ilula kakhulu.
Ukupholisa isihlalo se-hopper
Amanzi okupholisa avame ukusetshenziselwa ukupholisa isihlalo se-hopper. Inhloso yokupholisa ukuvimbela ukushisa okweqile okukhiqizwa yi-hopper ngenxa yokuphakelwa ngenkani. Ngaphezu kwalokho, futhi ukuvimbela izinga lokushisa lesigaba sokudla ngezikulufo ukuthi lingabi phezulu kakhulu. Uma izinga lokushisa lalezi zingxenye ezimbili liphezulu kakhulu, kuzothinta kakhulu ukuphakelwa kwe-hopper kanye nokuthuthwa kwezinto eziya phambili zingena esigabeni sokudla ngezikulufo.
Ukupholisa kwesikulufu
Uwoyela ophakathi ophehla ukushisa uvame ukusetshenziselwa ukupholisa izikulufo. Isakhiwo sejoyinti elijikelezayo sisetshenziselwa ukuxhuma imbobo ephakathi yesikulufo esijikelezayo nepayipi likawoyela. Uwoyela ophakathi ophehla ukushisa udlulela emzimbeni wesikulufo ngejoyinti elijikelezayo bese ususa ukushisa kwesikulufo ukuze kufezwe injongo yokupholisa isikulufo.
Uhlelo lokulawula lwe-B.
Uhlelo lokulawula lwe-extruder lubhekisela kakhulu ekulawuleni isivinini sokusebenza sesikulufu, izinga lokushisa lokushisa lesigaba ngasinye sebhareli, izinga lokushisa ledayi yokubumba, kanye nengcindezi edingekayo ekubumbeni izinto ezincibilikisiwe zemikhiqizo. Umsebenzi walawa madivayisi okulawula izingxenye ukuqinisekisa ukuthi i-extruder isebenza ngaphakathi kwezimo zenqubo ezibekiwe, ukuze i-extruder ikwazi ukukhiqiza imikhiqizo yepulasitiki ebunjiwe ngokuqina nangokushelela.
Njengoba eseneminyaka ecishe ibe ngu-20 embonini yemishini yokukhipha izinto ezihlakaniphile, ubelokhu ephethe izindima ezibalulekile eJwell Machinery, okuhlanganisa noMphathi Jikelele kanye noSihlalo Ojikelezayo. Kusukela ngo-2024, uphathe izinkampani eziningi ezingaphansi kwakhe, eqhuba ukwanda kwebhizinisi kanye nokuthuthukiswa kwezimboni, ngenkathi ehola ukusungula izinto ezintsha ekukhiqizeni izinto ezihlakaniphile kanye nokukhula komhlaba wonke.
