Ingxenye Eyinhloko Yezingcezu Ezintsha Zokubhoboza I-Carbide—Ama-Carbide Nozzles

I-nozzle iyingxenye eyinhloko ye-drill bit entsha ye-carbide, futhi ukusebenza kwayo kunquma ngokuqondile ukusebenza kahle kwe-rock-breaking ye-drill bit. Ngenxa yokuthi umlomo wombhobho ufakwe ngaphakathi kwebhidi elisha le-carbide elinosimende futhi ubude balo nobubanzi bangaphandle bulinganiselwe, izindinganiso ezikhona zokuklama umlomo wombhobho wemboni zifaneleka kuphela izimo ezinganqunyelwe, ngakho-ke umlomo wombhobho kufanele uklanyelwe ukukhiqiza umphumela wokubhoboza ongcono kakhulu. indiza. Ngaphansi kwesizinda sobunjiniyela esikhethekile sosayizi okhawulelwe wombhobho, idizayini yombhobho iyadingeka ukuze kuhlangatshezwane nezidingo ezilandelayo:

① Uma kudingeka amandla amakhulu ejethi, kungcono, ukuze idwala eliqinile liphuke. Ngesikhathi esifanayo, kuyadingeka futhi ukuthi i-jet stream iminyene ngangokunokwenzeka, engagwema ngempumelelo ukuphazanyiswa kwe-drill bit ehamba phambili ku-jet stream. Ukuminyana kwejethi kusho ukuthi ngemva kokushiya i-jet ku-nozzle, ukuhlangana kuba ngcono futhi i-diffusion angle ye-jet incane. Kodwa ngesikhathi esifanayo, kuyadingeka futhi ukuthi ukuvuleka kokuguguleka kwe-jet kukhulu ngokwanele, ukuze idwala likwazi ukuphulwa ngaphambili kwe-bit ehamba phambili, futhi amandla ethuluzi angancishiswa ngezinga elikhulu.

Umumo oyisisekelo we-jet ngemva kokushiya i-nozzle: ikakhulukazi ihlanganisa isigaba sokuqala kanye nesigaba esiyisisekelo, futhi kukhona isigaba sokulahla ngemuva kwesigaba esiyisisekelo, kodwa i-jet kulesi sigaba iphule amaconsi amanzi. Kukhona indawo ewumgogodla wokugeleza kwe-iso-kinetic esigabeni sokuqala, esagcina isivinini sokujova sokuqala. Isigaba ngasinye sinemisebenzi ehlukene ekusetshenzisweni kobunjiniyela obusebenzayo, ingxenye yokuqala ifanele ukusika nokuchotshozwa kwezinto, ingxenye eyisisekelo ifanele ukucutshungulwa kwendawo, ukuhlanza, ukususwa kokugqwala, njll., futhi ingxenye yokulahla isetshenziselwa ikakhulukazi ukupholisa nokususa uthuli. . Kulolu cwaningo, ingxenye ewumgogodla yejethi isetshenziswa kakhulu ukuphula amatshe. Ngakho-ke, umklamo we-nozzle kufanele wenze ingxenye eyinhloko ye-jet ibe yinde ngangokunokwenzeka, okungenza i-jet ibe namandla okuguguleka okuqinile ebangeni elide. Umongo omude we-iso-velocity wenza i-abrasive ukuthi iqhubeke nokusheshisa ngemva kokushiya umlomo wombhobho, ngaleyo ndlela ithuthukise isivinini sezinhlayiya eziqhumayo. Ukuminyana kwejethi ngokuyinhloko kuhlobene ne-engeli yokufinyela yenozi, futhi i-engeli yokufinyela yombhobho efanelekile kufanele ikhethwe ekwakhiweni kwenozzle.

②Ukuqinisekisa ukuthi impilo ye-nozzle ingahlangabezana nezidingo zobunjiniyela. Ngokuklama okunengqondo kwesakhiwo nokukhethwa kwezinto ezibonakalayo, impilo yesevisi ye-nozzle ifaniswa nempilo yokubhoboza, futhi ngesikhathi esifanayo, umnotho uyacatshangelwa, futhi izinto ezihlangabezana nezidingo zikhethwa ngokusekelwe kumanani anengqondo.

② Umbhobho uwuketshezi oluqinile olunezigaba ezimbili ezigeleza ngesivinini esikhulu, umlomo wombhobho ugqoka ngokushesha, ngakho-ke impahla yombobo inezidingo eziphakeme, umlomo wombhobho kufanele ube namandla okusebenza nokumelana nokugqokwa okuhle nokumelana nokugqwala. Njengamanje, i-tungsten carbide, idayimane, nezinto zokwenziwa zamatshe ayigugu zivame ukusetshenziswa. Ukuqina kombhobho we-carbide enosimende bungafinyelela ku-HRC93, amandla acindezelayo angafinyelela ku-6000MPa, futhi inokumelana nokugqokwa okuqinile. Imibhobho ye-tungsten carbide yenziwa ngendlela ye-powder metallurgy, futhi imibhobho ibunjwa ngokufa kwensimbi.

③ Ukuqina kwedayimane kuphakeme kakhulu, ukuqina kwe-Mohs kwe-10, kanye nekhono lokulimala kwe-anti-cavitation, impilo yinde kune-tungsten carbide, kodwa ngenxa yokuthungwa okuqinile, ukunemba kokupholisha kuphansi, ikhwalithi yejethi ifana ne-tungsten carbide nozzle. , intengo ibiza kakhulu, uma ucabangela umnotho ungayeka le nto. Kunezinhlobo eziningi zamagugu okwenziwa, njengamasafire, amarubi, nokunye. Ubulukhuni obuphezulu, nokumelana okuqinile nokuhuzuka kwejethi yamanzi, kodwa iyimpahla ephukayo, ukuphuka kalula. Ukuhlanganisa ikhwalithi ye-jet nozzles, ubunzima bokucubungula, intengo, nezindleko, inkampani yethu isebenzisa impahla ye-tungsten carbide ukwenza imibhobho.

I-ZZBETTER ikhiqiza izinhlobo ezahlukene zemibhobho ye-carbide, engahlangabezana nezidingo zamakhasimende ethu avela ezimbonini nasezinkundleni ezahlukene. Singakwazi futhi ukukhiqiza okungajwayelekile kanye neminye imikhiqizo ye-tungsten carbide. Siyakwamukela ukuvakashela iwebhusayithi yethu uma unentshisekelo: www.zzbetter.com.
