Umfutho womoya ophansi wezimayini i-hard rock DTH izingcezu zokubhoboza isando
Incazelo emfushane:
I-down-the-hole drill bit iyingxenye ebalulekile ye-down-the-hole drill, esetshenziselwa imisebenzi yokumba ngaphansi komhlaba.I-down-the-hole bit ngokuvamile iqukethe umzimba omncane namazinyo amancane.Umzimba we-drill bit iyisilinda sensimbi esinamandla okumelana nokuguga kanye nokumelana nokugqwala, okusetshenziselwa ukuxhuma amapayipi okubhoboza kanye nokudlulisa amandla okumba.Amazinyo e-drill bit atholakala ngaphansi komzimba we-drill bit, ngokudlulisela ukungqubuzana namandla okushayisana ngamatshe angaphansi komhlaba kanye nenhlabathi, inqubo yokusebenza kokumba iyenzeka.
Izici Eziyinhloko
1. Sikhetha izinkinobho ze-YK05 tungsten carbide, izici zazo: isivinini esikhulu sokuthwebula izithombe, ukumelana nokugqoka okuphezulu, Ifanele amatshe angu-98% (ikakhulukazi i-hard rock)
2. Izinto:35CrNIMoV
3. Izimbobo Ezishaywayo:2 noma 3.
4. Uhlobo Lwentambo: CIR,DHD njll.
5. Ubude beCarbide:0.5mm ubude kunomunye umkhiqizi ukuze ama-carbide angasuki.
Ukukhetha ukuma kobuso obuncane
1. I-Drop Center Bit Ngamazinga aphezulu okungena kumatshe athambile kuya kwamaphakathi aqinile futhi agqwalile.Izingcindezi zomoya eziphansi kuye kweziphakathi.Umkhawulo wokulawula ukuchezuka kwembobo.
2. Concave Face
Ibhithi yohlelo lokusebenza eyindilinga yonke ibhekene ngqo nokwakheka kwedwala eliqinile elimaphakathi ne-homo.Ukulawula okuhle kokuchezuka kwembobo kanye nomthamo omuhle wokushibilika.
3. Ubuso obuConvex
Ngamazinga okungena aphezulu kokuthambile kuya kokumaphakathi-okuqinile nokucindezela komoya okuphansi kuya kwamaphakathi.Iwukumelana kakhulu nokugeza insimbi, futhi ingase inciphise umthwalo futhi igqoke ezinkinobho zegeji, kodwa ukulawulwa kokuchezuka kwembobo okungekuhle.
4. I-Double Gauge Face
Lolu hlobo lomumo wobuso lufanele amazinga okungena ngokushesha ekwakhiweni kwamadwala aphakathi nendawo ukuya kwaqinile.Idizayinelwe ukucindezela komoya okuphezulu nokumelana okuhle ne-steel wash gauge bit.
5. I-Flat Face Bit
Lolu hlobo lomumo wobuso lufanele ukwakheka kwamatshe aqinile kuya kokuqina kakhulu futhi abrasive izicelo ezinomfutho womoya ophezulu.Amazinga okungena amahle ukumelana nokuwashwa kwensimbi.
