Unokukhetha njani i-tricone drill bits kwimigodi?
Uyilo lweamasuntswana e-triconekufuneka ziqhelanise neempawu iliwa ukuba yombiwa, kunye nolwakhiwo loyilo ezahlukeneyo zamkelwa ukuba isuntswana cone roller ezisetyenziselwa iintlobo ezahlukeneyo zamatye. I-tricone drill bit esetyenziselwa ukugrumba amatye athambileyo ikholisa ukuthatha umphakamo wamazinyo amade, kwaye isithuba sokusasaza amazinyo sincinci, ukuze kube lula ukuqengqeleka kunye nokukhuhla intwana yokomba kumphezulu wamatye, ukuze kuphunyezwe injongo yokucolwa kwamatye ngokukhawuleza. Kwi-hard rock drill, kusetyenziswa i-high toughness spherical tooth alloy, amazinyo axinene noko, kwaye ilitye liqengqeleka kakhulu ngexesha lenkqubo yokomba, ukuze kucuthwe ukutyibilika kangangoko kunokwenzeka. Ukuze kuncitshiswe ukunxiba kwelitye kwi-alloy, amazinyo e-alloy asetyenziswa ngokuqhelekileyo kwi-cone bit.
Inkqubo yokuthwala i-mining roller drill bit
I-mining roller drill bit idinga amandla amaninzi okuqhubela phambili ngexesha lenkqubo yokubhoboza, ngoko ke amandla okuthwala kunye neemfuno zoyilo lwesakhiwo ziphezulu kakhulu. I-roller enkulu yedayamithaamasuntswana econe ezintathungokuqhelekileyo sebenzisa i-roller - ibhola - roller (RBR) inkqubo yokuthwala: i-diameter encinci roller iibhithi ezine-cone ezintathu zisebenzisa i-roller - ibhola - isilayidi (RBF) inkqubo yokuthwala. Amandla eradial aveliswa zezi nkqubo zimbini zokuthwala kwinkqubo yokomba ubukhulu becala ngumthwalo omkhulu othwele i-roller, i-roller encinci okanye i-sliding bear idlala indima encedisayo, kwaye amandla e-axial athwalwa ikakhulu yi-front plane thrust bearing, kunye nokujula komngxuma wokomba kunye nokunxitywa kwe-axial force.i-tricone drill bit, i-axial force iphinda idluliselwe kwi-back thrust kunye nebhola yebhola, ukwenzela ukuba ubomi benkonzo ye-tricone drill bits yandiswe.
