Ukubaluleka Kokususa Igesi Nge-Vacuum Emigqeni Yokucubungula I-Plastic Extrusion
Kwesimanjei-extrusion yepulasitikiimigqa yokukhiqiza, ukususa igesi nge-vacuum kuyinqubo ebalulekile ethinta ngqo ikhwalithi yomkhiqizo, ukuzinza kwezinto, kanye nokusebenza kahle kokukhiqiza. Ngesikhathi sokushisa nokuncibilika, izinto ze-polymer ziguqulwa zibe isimo esincibilikisiwe esiqinile. Kodwa-ke, ngisho nezinto zokusetshenziswa zekhwalithi ephezulu ziqukethe umoya ovalelekile,umswakama, kanye namakhemikhali anomswakama aphansi anesisindo sama-molecule. Lezi zinto ezingafuneki ziyakhishwa ngesikhathi sokuncibilika kodwa zingahlala zivaleleke kalula ngaphakathi kokuncibilika uma zingasuswanga kahle.
Uma la magesi engakhishwa kahle, azogcinwa ku-extrudate yokugcina futhi aholele ezinkingeni eziningi zekhwalithi. Izinkinga ezivamile zifaka phakathi ukwakheka kwamabhamuza, imicu yesiliva, izikhala zomphezulu, izimpawu zokugeleza, kanye nezakhiwo zemishini ezingaguquki. Ezisetshenzisweni ezinembe kakhulu njengefilimu zokupakisha, ipulasitiki yobunjiniyela, kanye nemikhiqizo embozwe ngendwangu, ngisho neziphambeko ezincane ezihlobene negesi zinganciphisa kakhulu ukusebenza komkhiqizo kanye nenani lemakethe.
Ukuze kuxazululwe lezi zinkinga, kufakwa izinhlelo zokukhipha igesi nge-vacuum engxenyeni yokukhipha umoya ye-extruder. Ngokusebenzisa indawo yokukhipha igesi elawulwayo, uhlelo ludala indawo yokucindezela engemihle ekhipha njalo amagesi akhishwa ku-polymer encibilikisiwe. Lokhu kuvumela ukuthi ukuncibilika kube okufanayo, kuzinze, futhi kungabi nama-volatiles abanjwe ngaphambi kokungena ezigabeni zokwakheka, ukupholisa, kanye nokukhipha igesi nge-pelletizing. Ngenxa yalokho, ukukhipha igesi nge-vacuum kubhekwa kabanzi njengesinyathelo esibalulekile sokuqinisekisa ukuphuma kwe-extrusion kwekhwalithi ephezulu.
Izinselele Zokusebenza Ezibhekene Namaphampu E-Vacuum Ezinhlelweni Zokukhipha Igesi Emoyeni
Nakubaamaphampu okuhlanza umoya yimishini eyinhloko enesibopho sokugcina ingcindezi engemihle izinzile, indawo yokusebenza ezinhlelweni zokukhipha igesi eziphumayo iyadingeka kakhulu. Igesi ekhishwe ku-extruder ayiyona umoya ohlanzekile wenqubo; kunalokho, iyinhlanganisela eyinkimbinkimbi evame ukuquketheumhwamuko wamanzi, inkungu kawoyela, kanye nezinhlayiya ezincane ze-polymer noma izinsalela ze-resinzithathwe ezintweni ezincibilikisiwe.
Lezi zinto ezingcolisayo ziletha izinselele ezinkulu zokusebenzaamaphampu okuhlanza umoya. Uma sezingene ekamelweni lepompo, zinganqwabelana kancane kancane ezingxenyeni zangaphakathi ezifana nama-rotor, ama-vane, ama-seal, kanye nezinhlelo zikawoyela. Ngokuhamba kwesikhathi, lokhu kungcola kuholela ekunciphiseni ukusebenza kahle kokupompa, amazinga e-vacuum angazinzile, kanye nokusetshenziswa kwamandla okwandisiwe. Ipompo ingase futhi ibhekane nokushisa ngokweqile ngenxa yokumelana kwangaphakathi okwandisiwe.
Ezimweni ezimbi kakhulu, ukuchayeka isikhathi eside kugesi ongcolile kungabangela ukungalingani kwe-rotor, ukugqwala kwezingxenye zangaphakathi, ukuwohloka kukawoyela, ngisho nokubanjwa yimishini. Lapho kwenzeka ukwehluleka kwephampu, ukukhiqizwa kumele kumiswe, okuholela ekulahlekelweni okukhulu kwesikhathi sokungasebenzi kanye nezindleko zokulungisa. Le ngozi iba sobala nakakhulu ku-izinqubo zokukhiphaokubandakanya izinto ezisetshenziswe kabusha, ama-polymer anomswakama ophezulu, noma ukwakheka okuqukethe izigcwalisi kanye nezithasiselo, njengoba lezi zimo zivame ukukhiqiza amazinga aphezulu okungcola.
Ngakho-ke, ngenkathiamaphampu okuhlanza umoyaNjengoba zibalulekile ekusebenzeni kokukhipha igesi, kumele zivikelwe kahle ukuqinisekisa ukusebenza okuzinzile kwesikhathi eside ngaphansi kwezimo ezinzima zezimboni.
Umsebenzi, Isimiso Sokusebenza, kanye Nezinzuzo Zezihlungi Zephampu Ye-Vacuum Ezicelweni Zokukhipha I-Extrusion
Ukuze kuxazululwe lezi zinselele,isihlungi sephampu ye-vacuum or isihlukanisi segesi noketshezingokuvamile ifakwa phakathi kwembobo yomoya wokukhipha umoya kanye nendawo yokungena yephampu ye-vacuum. Umsebenzi wayo oyinhloko ukwelapha kusengaphambili umfudlana wegesi okhishwe ngaphambi kokuba ungene ephampu, ukuqinisekisa ukuthi igesi ehlanzekile kuphela efinyelela ku-uhlelo lwe-vacuum.
Iuhlelo lokuhlungaisebenza ngokuhlanganiswa kwezindlela zokuhlukanisa ngokomzimba. Okokuqala, amaconsi amakhulu oketshezi kanye nezinhlayiya ezisindayo kususwa ngokumiswa kwamandla adonsela phansi kanye nokushintsha kokugeleza okuqondisiwe ngaphakathi kwegumbi lokuhlukanisa. Ngemuva kwalokho, inkungu kawoyela ecolekile kanye namaconsi amancane abanjwa ngezinto zokuhlunga ezihlanganayo noma imidiya yokuhlunga esebenza kahle kakhulu. Ekugcineni, igesi ehlanziwe ikhishwa kuphampu ye-vacuum ukuze isebenze njalo.
Le nqubo yokuhlukanisa enezigaba eziningi inciphisa kakhulu umthwalo wokungcola ephampini ye-vacuum. Ngenxa yalokho, ukuguguleka kwangaphakathi kuncishisiwe futhi ukuzinza kohlelo kuthuthuka kakhulu. Izinzuzo zokusebenzisa i-isihlungi sephampu ye-vacuumkokubili ziyasebenza futhi zinomnotho.
Ngokombono wokusebenza, kusiza ukugcina amazinga e-vacuum azinzile, kuthuthukisa ukuphendula kohlelo, futhi kuqinisekisa ukusebenza kahle kokukhipha igesi njalo. Ngokombono wokulungisa, kwandisa impilo yesevisi yephampu ye-vacuum, kunciphisa imvamisa yokushintsha nokulungisa uwoyela, futhi kunciphisa izindleko zokulungisa zizonke. Ngokombono wokukhiqiza, kunciphisa isikhathi sokungasebenzi esingalindelekile futhi kusiza ukuqinisekisa ukusebenza okuqhubekayo nokuthembekile kwe-extrusion.
Ngaphezu kwalokho, i-uhlelo lokuhlungaingakwazi ukuzivumelanisa nezimo ezahlukene zokukhipha, okuhlanganisa ukuncibilika kwezinga lokushisa eliphezulu, izinto ezinamazinga aphezulu okugcwala, kanye nezinqubo ezinemithwalo yokungcola esindayo. Nakuba ivame ukubhekwa njengengxenye ewusizo ekwakhiweni kwesistimu,isihlungi sephampu ye-vacuumidlala indima ebalulekile yokuvikela. Iqinisekisa ukuthi iphampu ye-vacuum isebenza ngaphansi kwezimo ezihlanzekile, ngaleyo ndlela ivikele yonke inqubo yokukhipha igesi ye-vacuum futhi isekele ukukhiqizwa kwe-extrusion yepulasitiki okuzinzile, okusebenzayo, nokusezingeni eliphezulu esikhathini eside.
Uma ufuna izihlungi zephampu ye-vacuum ezithembekile nomaukuhlukaniswa kwegesi noketsheziizixazululo zezinhlelo zokukhipha igesi ngepulasitiki, sicela ukhululekeXhumana nathiIthimba lethu likulungele ukunikeza ukwesekwa kobuchwepheshe, izeluleko zokukhetha umkhiqizo, kanye nezixazululo ezenziwe ngokwezifiso ngokusekelwe ezidingweni zakho ezithile zohlelo lokusebenza.
