I-Polyurethane Screen Mesh Engavimbiyo Ukusebenza Kakanani

Indlela Iziphawulo Zingena Ukugcogwa Ziyakheza Ukusebenza Kwesikrini

Ukusebenza Kwendawo Nenkosana Yendalo: Inqaku Malunga Nezidingo Zokungena Ukugcogwa

Isikrini sangaphakathi sangopolyurethane sakhuluma ngoba sivikela ukuthi izinto zilande ngoba zineempawu ezimnene kumzimba walo kanye nesilinganiso esihle. Okukhawuleza kulolu hlelo kukuba konke kube yinxalenye engachanekanga yokudla, ikususa ukudla, kanti xa into ethile ichaphazeka, iyabuyela ngokushesha okufunakeleyo ukuthi ihlathe izinto ezingaqhubekanga. Le mibini iminikelo ivelisa ukuthi i-apertures ayizokwenzeka, ikakhulu ekubaleni ngezimo ezinzima eziphathelene nezithuthi ezinezintlangu. Uvavanyo lwasekuhlaleni lubonisa njengama-30 iphasenthi ngapha kwemida engaphucwangeni ikusasa kumasekriyini amadoda. Kunye, ubungakanani obuphezulu bokubuyela (ngaphezulu kuka-95% ngokwamava ase-ASTM D2632) buhlandla uhulumeni kuze kube yindlela yokuhlenga, okusiza ukuzothatha ngendlela efanelekileyo emisebenzini yokuhlengela komthubi nokuprosesa kwezixhobo ngaphandle kokuphazanyiswa okukhulu.

Polyurethane vs. Isteleli engenamandla kanye neRubber: Ukusebenza kweClogging kumisebenzi enobuningi obuphezulu

Emaphakethini okugcina ngamanzi, i-polyurethane ibangela ikhaya lika-stainless steel ne-rubber ngoba inemiphefumulo elihle kwempahla:

Loo ngxenye ibalulekile kakhulu ekusakelweni. I-polyurethane isebenza kahle ngokuphila kwe-slurry, ngaphandle kwezisabela ezingcono ezingaphakathi, ngaphandle kwezisabela ezidinga ukuvulwa kakhulu ukucula. Idatha yesihlalo ibonisa ukuthi kungcono ukuphula kakhulu ngama-30% ekunzulwini kwezimali kunamathuba e-rubber—kubalulekile kakhulu xa kusekelwa izinto ezibuthayo nezinezimo ezinezimo eziphezulu.

Umkhondo wokucula ngokwakhe emasiningeni amhlophe nezibuthayo

Impendulo yomkhondo othuthukileyo kanye nokubuyela kwamathuba emasiningeni athuthukileyo wezimali ezenzulwini

I-polyurethane isebenza ngokuthuthukileyo ukungavimbi emasiningeni athuthukileyo. Xa isekela izimali ezenzulwini—apho izisabela ezisendleleni zihlulela—ukubuyela kwakhe kusungula izimpawu ezincane zokubuyela zokuthuthukileyo ezithwalela izinto eziphakathi. Ngemikhondo phakathi kwe-800—1200 RPM, lokhu kusekelwa ngokwakhe kuthuthukisa, kungavimbi ukuthunywa kwamathuba kanye nokugcina ubunzima bomsebenzi.

Izimpawu ezibalulekile zifaka:

1. Ukuphazanyiswa kwe-energycala : Isihlangothi esiphilayo kamanzi kumelana ukwakha kwe-film yenkampani, kuyancipha ukudluliswa okumaphakathi komthwalo
2. Ukubuyela ngokwahlukana : Izinxalenye zezibuko (guba: 1.8—2.6 g/cm³) zibuyela ngokuthulasayo kunazo ezincwadini (1.3—1.5 g/cm³), kuyenhlela ukwahlukana nokuhlukaniswa

Phakathi kwezinkinga ezintathu kusuka ku-8%, i-elastic energy esigcinwayo kusihlangothi kuthinta isiphazamiso esizungezileyo ngemva kovibration, kuyethulula izinxalenye ezincane eziphakamiswe ngaphandle kokucula ngendlela. Lokhu kuyenzeka ukuthi kugcinwe ubungozi obungaphezu kuka-200 tons/hour emsebenzini wokucula izincwadi, kuyenhlela ukwahlukana ngaphezu kuka-20% kunazo ezinye izinketho eziphakeme.

Ukuthintana kwe-Throughput yasekhaya lokucula izincwadi kanye nokwenza kwezimali

Ukugcwaliswa kwe-screen kwenza izinkinga ezikhulu ekuprosesini kwebiza. Iziphazamiso ezigcwele zibeka ubude bokuthutha futhi zakhula ukusetshenziswa kwamandla. Isikrini sangaphambili se-polyurethane sivikela lezi zinkinga ngamafathi athintekayo nemvelo yethembeka, ekuvumela umsebenzi owodwa. Izinkampani zifinyelela izilinganiso ze-tonnage eziphezulu kabantu 15—30% futhi zibe namandla afutshane, konke ngaphandle kokulungiswa okuyisikhathi esikhulu.

Isibonelo: Ukunyuka Kwe-Throughput Kabi 32% Nenkokheli Yeminyaka Engu-18 Esikoleni Se-Washing Webiza

Isikole sendawo yokuwasha webiza eCentral Appalachia ekuprosesa i-bituminous coal enobumba obukhulu ibonakala ukugcwa kwe-screens ngaloku 90, kube yisikhathi esikhulu esingena phansi. Emva kokubuyisa i-rubber screens nge-sikrini se-polyurethane, isikhathi esingena phansi esingavunyelwa siphansi kabantu 80%, futhi ubude bokuthutha buhlangene kabantu 32%. Ezinye izinzuzo eziphathelene ngalesi sikhathi zihlanganise:

Ukwenza kwalu kwezimali ye-$740,000 kwalibona izimali eziyintathu emashumi namashumi amabili nesimanje ngeminyaka, kufakwa kwakhona umdla wokufakwa kwegama ngeminyaka eyishumi nayishiyagalombili. Ngaphezu koko, ukulungiswa kokuqinisekiswa kwebutha kakhulu kwalisa ubunjwala bekhohlwa ngamashumi ayisishiyagalombili, kumandla isikhungo ukulima izindleko eziningi zomkhakha—kubonisa konke indawo okukhawulezwayo yokudla kakhulu yenza kanjani izimali nokusebenza kakhulu ekugcineni kwezimali kakhulu.

Ukulungana Phakathi Kokuqhubeka Nezobuhlungu Ekusebenzeni Kakhulu

Lapho Kuphi Ukuchukwa Kokunyeleka KukaPolyurethane Kube Yilungiso?

I-polyurethane isebenza kahle ekumelweni kwembono futhi libuyela emva kokucindezeka, kodwa kukhona into eyayinxani xa izimo zihlala ziphelele ezinkozweni zokwakha. Xa isisitemu sihamba ngaphandle komphela noma ngaphezulu kwe-500 tons ngohora, wonke lokhu kufakelana kungubuthi. Isimo sibegcina kuqala ngaphambi kokuba kufanele kube khona, okusabalalisa ubuncike bekuphathelwa kwebhaskethi futhi kudla inhlaka yobude bokusebenza kwesikhwama. Sikhona lokhu kangakanani xa imithombo yokucindezeka iphumelela kuye kuye kwe-kilojoules eziyi-50 ngasikhathi esisodwa, ikakhulukazi uma kusebenziswa nezinto eziphelele noma ezingcono. Ukucindezeka okuphumelelayo kuhlolwa kakhulu imithombo yokubuyela emva ngexesha futhi kuthinta kakhulu lapho amandla ayihlala aphindaphindi.

Uma materials aqala ukulahlela ubunzima bazo emva kokusebenziswa kude, lokhu kungahlukahluka kakhulu indlela ekhokhelwa ngayo izinto ezahlukene. Ngakho ke manje amaphuzu aphezulu angcono ayathatha into ethile ephucawe. Ukuhlanganisa ubunjinga be-polyurethane nokuphila okunikeza inqubomgomo kunokwenza kufanele njalo. Okususelwe kukhona kukhombisa wonke umdla wethu owudingayo kumaterials elastic kodwa wenze inqubomgomo futhi iphinde iphila nangehlanza. Izixhobo zisebenza kahle kabanzi, zilondoloza amandla wokulinganisa, kanti azivimisele isimo sezimali njengoba kuyadingeka zintsho ezinye.

Imibuzo Evame Ukubuzwa

Yini into eyinhloko ye-polyurethane screen mesh?

I-polyurethane screen mesh inika amandla okungakhiphali ngokuthi yenzeka ikhaya eliphaphazelayo futhi inikeza umdla wokudonsa, okwakhathaza ukuhlola kwizimo ezinezithelo eziningi.

Kani njalo i-polyurethane ikilinganiswa no-stainless steel ne-rubber ngokulinganana nokukhipha?

I-Polyurethane ikhuphela isitayeni esiphuthayo nesilawuli ngoba yenziwa yezici zokuxoshelana nokubuyisela, kanti kube yinkulu yokudala ukuphazanyiswa kwezinyanga futhi kuvuselela ukusebenza kwemisebenzi.

Ingaba i-polyurethane mesh yesikrini ingasebenze ngokusheshayo emathalathini okuhlambalala amagwagwa?

Yebo, i-polyurethane meshes yesikrini ivikela ukusebenza okuphinde okuphinde ngamathuba aphezulu kanye nezimali ezingaphansi ngokuthatha isikhathi esingaphansi sokulahlekelwa kwebhloko kanye nokudinga kokulungisa.
