I-Carbide Insert Wear Failure kanye nezixazululo

Izingubo zokugqoka ze-tungsten carbide zisetshenziselwa ukusika i-casing yensimbi namapulaki, ukususa udoti wembobo ephansi futhi kuvikelwe ingaphezulu lamathuluzi we-downhole. Izinhlobo ezahlukene zezingxenye zokugqoka ze-tungsten carbide, ezifana nonxande, isikwele, nxazonke, ingxenye eyindilinga, kanye ne-oval, zingakhiqizwa. Lokhu kufaka kuqinisekisa ukuthi i-alloy yokubhula iyakwazi ukungena ngokugcwele isikhala phakathi kwe-blade nokokufaka, inikeze ibhondi evikelekile ongayethemba. Zenzelwe ukuthi zisetshenziswe ngenduku yethu eyinhlanganisela ukunikeza ikhwalithi ephezulu.

Kungani i-Carbide ifaka i-Wear Yehluleka?

Ukugqokwa kwamathuluzi kuchaza ukwehluleka kancane kancane kwamathuluzi okusika ngenxa yokusebenza okuvamile. Yigama elivame ukuhlotshaniswa namathuluzi asetshenziswa njengesibonelo ekuphenduleni, ekugayeni, ekubholeni kanye nezinye izinhlobo zemisebenzi yomshini lapho kwenziwa khona ama-chips. Singase futhi sithi “Siqale ngomphetho omusha futhi ekuqaleni kokuhlinzwa konke kwakuhamba kahle. Ngemva kwesikhathi esithile, izinto zaqala ukushintsha. Ukubekezelela bekuphelile, ukuphela kwendawo bekukubi, ukudlidliza kwenzeka, kwasetshenziswa amandla engeziwe kanye nezinye izinto eziningi ezingenzeka lapho umkhawulo usufike ekugcineni”.

Yiziphi izinyathelo esingazithatha ukuze simise lokhu kuguga?

Sebenzisa isivinini sokusika se-Vc=0m/min noma ungawasebenzisi amathuluzi. Singathonya indlela yokuziphatha ngokushintsha idatha yomshini. Kukhona ubudlelwano phakathi kwempahla ethile kanye nezindlela zokugqoka. Inhloso wukuba ne-Flank Wear ebikezelwayo. Ukugqokwa okuqhubekayo nokungagqoki kweziqongo kusinikeza ukuziphatha okubikezelwayo. Ukugqoka okungahleliwe kubi futhi kusinika ukukhiqiza okungalindelekile (ivolumu). Isicaphuna esihle esivela kuthisha waseMelika owaziwayo wokusika insimbi: "Ukwazi inkinga kuyingxenye yempi!" - UMnu Ron D. Davies "

Nasi isibonelo Sokufeyila Kwe-Isert Wear:Notching

Imbangela

Ukufaka i-notching kubangelwa lapho ingaphezulu le-workpiece liqinile noma liluma kakhulu kunempahla eqhubekayo, isb. ukuqina kobuso kusuka ekusikekeni kwangaphambilini, izindawo ezifojiwe noma eziphonswe ngezikali ezingaphezulu. Lokhu kubangela ukuthi i-insert igqoke ngokushesha kuleyo ngxenye yendawo yokusika. Ukugxila kwengcindezi yendawo nakho kungaholela ekuqaphelweni. Njengomphumela wokucindezeleka okucindezelayo eduze komkhawulo wokusika - nokuntuleka okufanayo ngemuva komkhawulo wokusika - ukufakwa kugcizelelwe ikakhulukazi ekujuleni komugqa wokusika. Umthelela wanoma yiluphi uhlobo, olufana nokufakwa okuqinile kwe-micro ku-workpiece material noma ukuphazamiseka okuncane, kungabangela inothi.

Okufanele kuqashelwe

•Ukuchopha noma ukuchopha ekujuleni kwendawo esike kuyo okokufaka.

Ukulindele nini

•Izinto ezinezinga eliphezulu (izinto ezisansimbi noma ezifojiwe) noma i-oxidation.

•Izinto eziqinisa amandla.

Izenzo Zokulungisa

•Nciphisa okuphakelayo futhi uguqule ukujula kokusika lapho usebenzisa amaphasi amaningi.

•Khulisa isivinini sokusika uma wenza ingxube ye-temperature ephezulu (lokhu kuzonikeza ukuguga okwengeziwe kweflank).

•Khetha ibanga le-carbide eliqinile.

•Sebenzisa i-chip breaker eklanyelwe ukudla okuphezulu.

•Vimbela unqenqema olwakhiwe, ikakhulukazi kuma-alloys angenasici kanye nethempe eliphezulu.

•Khetha i-engeli encane yonqenqema.

•Uma kungenzeka sebenzisa okufakwayo okuyindilinga.

I-ZZBetter stock ukukhethwa okuphelele kokufakwa kokuvikela ukugqokwa. Ukufakwa kuyatholakala ngemiklamo ehlukahlukene kanye nokuma, kufaka phakathi i-trapezoidal. Uma sezisetshenziswe ethuluzini, zingagcwaliswa ngempushana yesifutho sensimbi noma induku eyinhlanganisela ukuze zinikeze indawo engagugi ukuze kuhlangatshezwane nezidingo zakho zohlelo lokusebenza.

Uma ufuna imikhiqizo yekhwalithi enikeza ukuguga okuvelele kanye nokumelana nomthelela sinalokho okufunayo. Sithathe ibhizinisi elifaka ukuvikela ukugqokwa silibeke kwelinye izinga ngokuqina okuphezulu, ubukhulu obuhlukahlukene, kanye nefekthri ngokuqondile.
