Tungsten Carbide Metsi a Jet Nozzles
Ke eng e etsang hore tungsten carbide e be khetho e ntle bakeng sa li-nozzles?
• Super coarse grain hard alloy virgin raw material , 100% alloy ka ho tobetsa le ho sintering , e le hore ho thatafala le ho tiea ha mochini oa ho cheka ho eketsehile ka 30% ka nako e le 'ngoe.
• Moralo o ikhethileng, lebelo la ho cheka le ho cheka li phahamisa 20%, nako ea bophelo e eketsa 30%
• Botsitso bo boholo libakeng tse nang le mocheso o phahameng le maemo a khatello
• Qetello e ntle e etsang hore ho be bonolo ho e hloekisa
• Ho hanyetsa ho hoholo ho apara, ho hanyetsa abrasion
• Chelete e sebetsang hantle ka lebaka la nako e telele ea bophelo le litlhoko tse sa tsotelleng tsa tlhokomelo.
Molemo ka ho Fetisisa Ntlha ea Bohlokoa
(1) tlas'a maemo a itseng, joalo ka bophara ba nozzle, Angle ea ente le sebaka sa spray, ha khatello ea jete e phahama, phello ea ho pshatla lefika e tla ba betere;
(2) tlas'a boemo ba hore bophara ba nozzle, ente ea Angle le lebelo la ho sisinyeha ha nozzle li lula li sa fetohe, sebaka se nepahetseng sa ho fafatsa sea eketseha ka ho eketseha ha khatello, ho fihla makhetlo a 32.5 a bophara ba nozzle ho 200MPa;
(3) moelelo oa lebelo la ho sisinyeha ha nozzle ke ho bonts'a nako ea ts'ebetso ea lejoe la khoholeho ea jete.Ha e le ka tlase ho 2.9mm/s, e na le tšusumetso e fokolang ho phello ea khoholeho ea lejoe.
(4) ha khatello e le tlase ho 150MPa, khatello ea jet ea eketseha 'me molumo oa ho robeha ha majoe ka matla a yuniti o eketseha ka potlako;leha ho le joalo, ha khatello e ntse e eketseha ho ea pele, molumo oa ho pshatla lejoe ka matla a yuniti o fokotseha hanyenyane, 'me katleho ea ho pshatla lefika ke e phahameng ka ho fetisisa ho 150MPa.
