isixwayisi ithiyori yesikrini nokukhethwa

Isikrini sokudlidliza siyinsiza ebaluleke kakhulu yokufaka amatshe nokuhlola embonini yezimayini.Ingakhuphula kakhulu izinga lokusetshenziswa kwetshe futhi yehlise izinga lokwehluleka kwemishini yokwenza izinqubo ezilandelayo.Ihlukile kwizikrini zesandla zendabuko.Ukusiza wonke umuntu Ukuyiqonda kahle le mishini,u-Hiside uhlanganise imigomo namasu wokukhetha wezikrini zokudlidlizela inkomba yakho.

Isixwayisi semibono yesikrini

Inqubo yokusebenza kwesikrini esidlidlizelayo izosebenzisa ukudlidliza okuphindayo okwenziwe yinjabulo ekhangayo,futhi isando esijikelezayo esingaphezulu sesidlidlizi sizobangela ubuso besikrini esidlidlizelayo ukwakha ukudlidliza kwendiza.Isisindo sokujikeleza esingezansi senza ukuthi indawo yesikrini ikhiqize ukudlidlizela okumise okwesigaxa,futhi umphumela wayo ohlangene wenza indawo yesikrini ikhiqize ukudlidliza okuzungeza kabili;

Inqubo yokuhlukanisa izinto ezihlakazekile ezinobukhulu bezinhlayiyana ezihlukene ngesikhala esisodwa noma esinezingqimba eziningi ezinemigodi esatshalaliswe ngokulinganayo kaninginingi emazingeni ahlukahlukene abizwa ngokuthi yi-sieving.Izinhlayiya ezinkulu kunembobo yesisefo zihlala ebusweni besikrini,bese izinhlayiya ezincane kunembobo yesisefo zidlula emgodini wesihlungo,ekugcineni izinhlayiya ezimahhadla nezinhle zihlukaniswa bese inqubo yokuhlola iphothuliwe.

Isici sokuhlola i-vibration

Izici zento okufanele ihlolwe(okuqukethwe kwento engaphansi kwesihlungo,okuqukethwe inhlayiya enzima kuya kokusefa,okuqukethwe umswakama nobumba kulokho okubhaliwe,ukwakheka kwento,amandla adonsela phansi impahla,njll.);

Ukwakheka komshini wokuhlola(indawo yesikrini,inani lezendlalelo zesikrini,usayizi womgodi wesikrini kanye nokuma,isilinganiso somgodi wendawo yesikrini,imodi yokunyakaza komshini wokuhlola,i-amplitude nemvamisa,njll.);

Izidingo zenqubo yokuhlomula(amandla wokucubungula,ukusebenza kahle kokuhlola,indlela yokuhlola,ukuthambekela komshini wokuhlola),njll.

Isimiso sokukhetha sesikrini esidlidlizayo

(1)Ngemuva kokunquma indawo yokuhlola,ububanzi bendawo yesikrini kufanele okungenani bube ngu-2,5 kuya ku-3 ubukhulu bento ebaluleke kakhulu ukuvimba ukuthi isikrini singavinjelwa izingcezu ezinkulu zempahla.

(2)Ukuze isihlungo sibe sezimweni ezinhle zokusebenza,isilinganiso sobude nobubanzi besisefo kufanele sikhethwe ebangeni elingu-2 kuye ku-3.

(3)Kufanele kukhethwe okokusebenza okungaphezulu kwesikrini nokwakheka ukuze kuvumelane nezimo zokusebenza.

(4)Ukunqunywa kosayizi wembobo yesisefo.Kuma-sieve amahle nama-sieve agobile,lapho ama-sieve womugqa wokudlidliza asetshenziselwa ukuhlolwa kwezinhlayiyana ezinhle,ubukhulu be-sieve slit buphinda izikhathi ezi-2 kuye kwezingu-2.2 ubukhulu bezinhlayiya zokuhlukanisa,futhi ubukhulu abukho ngaphezu kwezikhathi ezi-3;okwe-sieve esidlidlizelayo,Okokuhlolwa kwezinto ezisemaginini aphakathi nendawo,ubukhulu bemeshi buyizikhathi eziyi-1.2 ubukhulu bezinhlayiya zokuhlukanisa;lapho isetshenziselwa izinto ezi-graarse-grained,usayizi we-mesh ngu-1.05 wosayizi wezinhlayiyana zokuhlukanisa;kuzikrini zamathuba,usayizi we-mesh imvamisa ukuhlukaniswa kwangempela izikhathi ezi-2 kuye kwezingu-2,5 usayizi wezinhlayiyana.

(5)Nquma ukuthi uzosebenzisa yini ama-sieve anezendlalelo ezimbili noma amaningi.Lapho uhla losayizi wezinto okufanele zihlolwe lubanzi,lapho isendlalelo esimbili sisetshenziswa njengesikrini sendlela eyodwa,amandla wokucubungula womshini wokuhlola angathuthukiswa,futhi isikrini esingezansi singavikelwa,nempilo kwesikrini engezansi kungenziwa eside.Ukukhethwa kwesayizi lomgodi wesisefo sesihlungo esingenhla sesisefo esiphindwe kabili kufanele ngokuvamile kunqunywe ngokuya ngezimpawu zosayizi wezinhlayiyana zokuphakelayo,nenani lezinto ezingaphansi kwesihlungo esingenhla,esilingana no-55-65%kwenani loqobo lokuphakelayo,kungathathwa njengembobo yesisefo.usayizi.

Qaphela ukuthi lapho okuqukethwe kwe-particle engaphansi kwe-sieve entweni eluhlaza kungaphezu kwama-50%,kunezinhlayiya eziningi ezinzima,okusetshenziswayo kuqukethe udaka olunamandla kakhulu nokuqukethwe kwamanzi amaningi,kufanele uzame ukugwema ukusebenzisa ungqimba olukabili i-sieve njengesefa yongqimba olulodwa.

(6)Nquma indawo esebenza kahle yesisefo.Indawo yokuhlulwa ebalwe ngokuya ngezidingo zenqubo yokukhiqiza iyindawo esebenza kahle yesihlungo,futhi ubukhulu besihlungo yindawo eqanjwe ngesihlungo.Esikrinini esidlidlizelayo esisetshenziselwa ukuhlolwa kwezinto ezinosayizi ophakathi nendawo,indawo eyi-sieving esebenzayo kufanele ibe ngu-0.8～0.85 wendawo eqokiwe ye-sieve Times.Vele,lokhu kuhlobene kakhulu nezinga lokuvula lesihlungo esikrinini.

(7)Izikrini zokudlidliza okunzima kakhulu zisetshenziselwa izinto ezingaphezulu kuka-200mm;izikrini zokunyakaza eziyindilinga zisetshenziselwa kakhulu izinto ezingaphezulu kwe-10mm;izikrini eziqondile zokudlidliza nezikrini zokudlidliza ezihamba kakhulu zisetshenziselwa ukwenza i-desilting,ukuchelela amanzi nokugaba.

(8)Uma izimo zivuma,kufanele kukhethwe isihlalo sesihlalo kuqala ukwenza lula ukuhlolwa nokugcinwa.Lapho kufanele kukhethwe isikrini sokulenga,ukuphakama kokuphakamisa kufanele kuncishiswe ukunciphisa uhla lokujikisa kwesikrini esidlidlizelayo nokwenza lula imisebenzi yokukhiqiza.

Lokhu okungenhla kuyisimiso namakhono wokukhetha wesikrini esidlidlizelayo esihlanganiselwe u-Hiside.Ngiyethemba ukuthi ingasiza wonke umuntu.
