Ina ia faʻaleleia le faʻatinoga o le tricone drill bit, e tele vaega taua ua faʻatinoina.
1、O le C-Center jet, mo se faʻataʻitaʻiga, ua mamanuina e puipuia ai le fausiaina o se polo i totonu ole vaega.O lenei vaega e fesoasoani e faʻaumatia soʻo se vaega vai i le pito i lalo o le vaieli, faʻavavevave le tafe agai i luga o tipi vili, ma iu ai ina faʻaleleia le saoasaoa o le ulu (ROP).
2、O le maualuga o le saturation NBR bearings ua tuʻufaʻatasia i le mamanu o le tricone drill bit e fesoasoani e faʻaitiitia le faʻamaufaʻailogaina ma faʻaleleia le faʻamaoni o le faʻamaufaʻailoga.O lenei suiga e taua tele aua e mafai ona fesoasoani e puipuia le tafe, lea e mafai ona taugata ma matautia.
3、e taua foi le vaega o le puipuiga o le G-Gauge aua e faʻaleleia ai le gafatia o le fuaina o le tricone drill bit ao faʻaumiina lona ola tautua.Faatasi ai ma lenei faʻaaliga, e mafai e tagata faʻaoga ona faʻamoemoe e sili atu le saʻo fua, lea e mafai ona taʻitaʻia ai le lelei o le viliina faʻatinoga ma taunuʻuga.
4、I le mea mulimuli, o le fa'aopoopoina o se laina fa'aopoopo o nifo i le va o le taper pito i tua ma le tafe mai fafo ua fa'amaonia e avea o se auala aoga e tipi ai le lua ma puipuia le cone.O lenei vaega e fesoasoani e fa'aitiitia le ofuina ma le masaesae i luga o le tricone drill bit, e maua ai le umi o le ola ma sili atu le fa'atinoga.
I se aotelega, o le tricone drill bit o se meafaigaluega faʻapitoa ma faʻatuatuaina e mafai ona faʻaogaina mo le tele o talosaga vili.E ala i le tu'ufa'atasia o mea fou e pei o le C-Center jet, maualuga saturation NBR bearings, G-Gauge protection, ma se laina fa'aopoopo o nifo, o le tricone drill bit's performance and lifespan e mafai ona matua fa'aleleia.
Uiga
1. Drill Bit Connection faia e tusa ai ma tulaga API.
2. E mafai ona matou fetuutuunai le lapopoa e tusa ai ma lau rig.
3. Faʻataʻitaʻiina faʻataʻitaʻiga faʻapipiʻi ma faʻataʻitaʻiga o loʻo faʻaauau pea ona tuʻuina atu se tulaga maualuga o le faʻatinoga ma le faʻamaoni.
4.Optimized hydraulics e maua ai le ROP faʻateleina e ala i le aveeseina lelei o tipi ma faʻamautinoa le faʻaogaina o le papa fou i luga o suiga uma o le fausaga.
