ICandelo eliPhambili leeMibhobho yeCarbide eNtsha-Imibhobho yeCarbide

Umbhobho licandelo eliphambili le-drill drill bit entsha, kwaye ukusebenza kwayo kubeka ngokuthe ngqo ukuphumelela kwe-rock-breaking ye-drill bit. Ngenxa yokuba umlomo wombhobho ufakwe ngaphakathi kwiqhekeza elitsha le-carbide drill kunye nobude bayo kunye nobubanzi bangaphandle bulinganiselwe, imigangatho yoyilo yoyilo lombhobho woshishino olukhoyo lufanelekile kuphela kwiimeko ezingaphelelanga, ngoko ke umlomo kufuneka uyilwe ukuvelisa isiphumo esihle sokubethelwa. ijethi. Ngaphantsi kwemvelaphi yobunjineli obukhethekileyo bobungakanani obulinganiselweyo bombhobho, uyilo lombhobho luyafuneka ukuhlangabezana nezi mfuno zilandelayo:

① Ukuba mkhulu amandla empembelelo yejethi efunekayo, ngcono, ukuze ilitye eliqinileyo likwazi ukwaphuka. Ngexesha elifanayo, kuyafuneka kwakhona ukuba i-jet stream ibe yinkimbinkimbi ngokusemandleni, enokuthi iphephe ngokufanelekileyo ukuphazamiseka kwe-drill drill bit kwi-jet stream. Ubuninzi bejethi buthetha ukuba emva kokuba i-jet ishiya i-nozzle, i-convergence ingcono kwaye i-angle ye-diffusion ye-jet incinci. Kodwa kwangaxeshanye, kuyafuneka ukuba i-aperture ye-jet erosion inkulu ngokwaneleyo, ukwenzela ukuba ilitye likwazi ukuphulwa kwangaphambili kwi-bit ehamba phambili, kwaye amandla esixhobo angancitshiswa kakhulu.

Ubume obusisiseko bejethi emva kokushiya i-nozzle: ikakhulu ibandakanya icandelo lokuqala kunye necandelo elisisiseko, kwaye kukho icandelo lokulahla emva kwecandelo elisisiseko, kodwa ijethi kweli candelo liye laphuka libe ngamaconsi amanzi. Kukho iconical iso-kinetic flow core ummandla kwicandelo lokuqala, elisagcina isantya senaliti yokuqala. Icandelo ngalinye linemisebenzi eyahlukeneyo kwizicelo zobunjineli obusebenzayo, icandelo lokuqala lifanelekile ukusika izinto kunye nokutyumza, icandelo elisisiseko lilungele ukulungiswa kwendawo, ukucocwa, ukususwa kwe-rust, njl., kwaye icandelo lokutshatyalaliswa lisetyenziselwa ukupholisa kunye nokususwa kothuli. . Kolu phononongo, inxalenye engundoqo yejethi isetyenziswa ikakhulu ukuqhekeza amatye. Ke ngoko, uyilo lombhobho kufuneka lenze icandelo eliphambili lejethi libe lide kangangoko, nto leyo enokwenza ukuba ijethi ibe namandla okhukuliseko olomeleleyo kumgama omde. I-iso-velocity core ende yenza ukuba i-abrasive iqhubeke nokukhawuleza emva kokushiya i-nozzle, ngaloo ndlela iphucula isantya se-particle abrasive. Ubuninzi bejethi bunxulumene ikakhulu ne-angle yokucutha yomlomo, kwaye i-angle yokunciphisa umlomo efanelekileyo kufuneka ikhethwe kuyilo lomlomo.

②Ukuqinisekisa ukuba ubomi bombhobho bunokuhlangabezana neemfuno zobunjineli. Ngokuqulunqwa kwesakhiwo esifanelekileyo kunye nokukhethwa kwezinto eziphathekayo, ubomi benkonzo ye-nozzle buhambelana nobomi be-drill, kwaye ngelo xesha, uqoqosho luyaqwalaselwa, kwaye izinto ezihlangabezana neemfuno zikhethwa ngokusekelwe kumaxabiso afanelekileyo.

② Umbhobho ngulwelo oluqinileyo olunamanqanaba amabini ahamba ngesantya esiphezulu, umbhobho unxiba ngokukhawuleza, ngoko ke izinto zombhobho zineemfuno eziphezulu, umlomo kufuneka ube namandla omatshini kunye nokunganyangeki kokunxiba kunye nokuxhathisa ukubola. Okwangoku, i-tungsten carbide, idayimane, kunye nezixhobo ezenziwe ngamatye anqabileyo zisetyenziswa ngokuqhelekileyo. Ukuqina komlomo we-carbide owenziwe ngesamente unokufikelela kwi-HRC93, amandla oxinzelelo anokufikelela kwi-6000MPa, kwaye inokumelana okuqinileyo nokunxiba. Imilomo ye-tungsten ye-carbide yenziwe nge-powder metallurgy method, kwaye imilomo ibunjwe ngentsimbi yokufa.

③ Ubunzima bedayimani buphezulu kakhulu, ubunzima be-Mohs ye-10, kunye ne-anti-cavitation yomonakalo amandla, ubomi bude kune-tungsten carbide, kodwa ngenxa yobunzima obunzima, ukuchaneka kokupholisha kuphantsi, umgangatho wejethi ufana ne-tungsten carbide nozzle. , ixabiso libiza kakhulu, ngokuqwalasela uqoqosho lunokunikezela ngale nto. Kukho iintlobo ezininzi zamatye anqabileyo, anjengesafire, iirubhi, njalo njalo. Ubulukhuni obuphezulu, kunye nokuchasana okunamandla kwi-jet abrasion yamanzi, kodwa yinto enqabileyo, kulula ukuyiqhawula. Ukudibanisa umgangatho wemilomo yejethi, ubunzima bokuqhuba, ixabiso, kunye neendleko, inkampani yethu isebenzisa imathiriyeli ye-tungsten carbide ukwenza imilomo.
