Ungakhetha kanjani izingcezu ze-tricone zokumba izimayini?
Umklamo weizingcezu ze-triconekufanele ivumelane nezici zedwala okufanele libhobozwe, futhi izakhiwo zokuklama ezahlukene zamukelwa i-roller cone bit esetshenziselwa izinhlobo ezahlukene zamadwala. I-tricone drill bit esetshenziselwa ukubhola idwala elithambile ngokuvamile ithatha ubude bezinyo olude, futhi isikhawu sokusabalaliswa kwamazinyo sincane, ukuze kube lula ukugingqika nokuklwebha kwetshe lokubhoboza endaweni yedwala, ukuze kufezwe inhloso yokuchotshozwa kwamadwala ngokushesha. Ku-hard rock drill, i-high toughness spherical tooth alloy isetshenziswa, amazinyo aminyene ngokuqhathaniswa, futhi idwala ligoqeka kakhulu phakathi nenqubo yokumba, ukuze kuncishiswe ukukhuhla kokushelela ngangokunokwenzeka. Ukuze unciphise ukuguga kwedwala ku-alloy, amazinyo e-alloy avame ukusetshenziswa ku-roller cone bit.
I-Bearing system ye-minining roller drill bit
I-minining roller drill bit idinga amandla amaningi okuqhubela phambili phakathi nenqubo yokubhoboza, ngakho-ke amandla okuthwala kanye nezidingo zokuklama kwesakhiwo ziphezulu kakhulu. I-roller enkulu yobubanziizingcezu ezintathu zamakhoningokuvamile sebenzisa i-roller - ibhola - roller (RBR) uhlelo lokuthwala: i-diameter encane roller amabhithi amakhoni amathathu asebenzisa i-roller - ball - slide (RBF) yokufaka uhlelo. Amandla eradial akhiqizwa yilawa masistimu amabili okubhoboza ohlelweni lokumba ikakhulukazi umthwalo othwele ama-roller, i-roller encane noma i-sliding bear idlala indima eyisizayo, futhi amandla e-axial athwalwa ikakhulukazi i-front plane thrust bear, ngokujula kwembobo yokumba kanye nokuguga.i-tricone drill bit, amandla e-axial aphinde adluliselwe ekuthwaleni kwe-thrust yangemuva kanye ne-ball bear, ukuze impilo yesevisi ye-tricone drill bits inwetshiwe.
