Iimpembelelo zeJethi yaManzi yokuJonga kwiiTubhu

Kwi-abrasive water jet cutting, i-tungsten carbide water jet egxininise ityhubhu yinxalenye ebalulekileyo. Emva koko, kule ityhubhu apho amanzi aphezulu kunye ne-abrasives egxininisekile kwi-jet yokusika esebenzayo. Ngethuba le nkqubo, iinkqubo zomzimba kwi-tube zichaphazela kakhulu isantya sokugqibela kunye nokuchaneka kwejethi yokusika kunye nobubanzi be-kerf kwiindawo zokusebenza.

Nangona kunjalo, imilo kunye nobungakanani bejethi yamanzi egxininise kwityhubhu inefuthe njani?

Into ebalulekileyo ye-jet yamanzi egxininise ityhubhu ubude bayo kunye nendawo yokungena.

Ngokudibanisa nendawo yokungena, ubude bombhobho wejethi wamanzi ongaguqukiyo bunquma kakhulu isantya kunye nokugxila kwijethi ephumayo. Ijethi yamanzi ecocekileyo eyenziwe yi-orifice iphuculwe ngesanti enqabileyo kwigumbi lokuxuba, eliphambi kombhobho wokugxila. Kule nkqubo, zombini i-angle ye-inlet echanekileyo kunye nobude obuncinci be-tube buyimfuneko ukulungisa amaqhekeza abrasive kwi-velocity kunye nolwalathiso lwejethi yamanzi. Ngaloo ndlela, inokudala ijethi yokusika egxininisekile kwaye isebenzayo. Nangona kunjalo, ityhubhu egxininisiweyo ye-carbide ayifanele ibe yinde kakhulu ngenxa yokuba i-friction kwindawo yangaphakathi inokunciphisa i-jet.

Ububanzi bangaphakathi betyhubhu ye-jet nozzle yamanzi ibalulekile kugxininiso oluchanekileyo lwejethi yokusika.

Ngokuqhelekileyo, umngxuma wetyhubhu ogxininisiweyo kunye ne-orifice kufuneka ilungelelaniswe ngokuchanekileyo. Ukugxila, ukunxitywa okunje ngamaza kancinci kunokubonwa, ngakumbi kwindawo yokungena ityhubhu. Ukuba ukulungelelaniswa akuchanekanga, ukunxiba kuyanda kwaye kuchaphazela umgangatho wejethi emva kwexesha elifutshane lokusetyenziswa. Oku kunokukhokelela ekuphambukeni kwejethi yokusika kwi-outlet ye-tube kunye nokuwohloka komgangatho wokusika kwi-workpiece. Ezinye izinto ezichaphazela ngokukodwa ubomi bemveliso yi-inlet velocity yejethi yamanzi kunye nomlinganiselo kunye nomgangatho we-abrasive kwaye, ngokuqinisekileyo, umgangatho wezinto eziphathekayo ityhubhu yokugxila.
