Yuav ua li cas los daws cov kabmob puas hauv Tricone ntsis?

Raws li lub hauv paus tseem ceeb ntawm cov roj thiab roj drilling thiab trenchless engineering cov cuab yeej, cov kabmob yog "lub plawv" ntawm cov khoom siv.tricone laum ntsis. Txawm li cas los xij, nws feem ntau ua tsis tiav thaum ntxov vim qhov kev poob qis heev, dhau los ua qhov mob tseem ceeb txwv qhov kev ua haujlwm drilling.

Muaj peb lub laj thawj tseem ceeb rau kev puas tsuaj rau cov kabmob: 

Ua ntej, siab cuam tshuam loads thiab alternating stresses downhole. Lub radial runout thiab axial extrusion ntawm lubkhob khobthaum lub sij hawm drilling tau yooj yim ua rau qaug zog spalling ntawm bearing raceway; 

Thib ob, ntxeem tau ntawm cov dej drilling thiab txiav. Cov tsoos tsoos tsis tuaj yeem cais cov impurities zoo, ua rau muaj kev sib tsoo ntawm cov kabmob; thib peb, lubrication tsis ua hauj lwm. Nyob rau hauv high-temperature thiab high-pressure ib puag ncig, lubricating roj yog yooj yim diluted los yog carbonized, poob nws cov nyhuv tiv thaiv.

Txhawm rau hais txog cov ntsiab lus mob no, Drillmore tau tsim peb lub hom phiaj tseem ceeb thev naus laus zis los txhim kho cov kabmob zoo. 

Ua ntej, peb txais yuav a carburizing zog txheej txheem rau high-carbon chromium bearing steel, uas ua rau kom lub ntsej muag hardness ntawm cov kabmob mus rau saum HRC62 thaum tuav lub toughness ntawm cov tub ntxhais, ua tiav ob qho kev txhim kho hauv kev cuam tshuam thiab hnav tsis kam. 

Thib ob, peb tau tsim ib qho tshiab multi-channel labyrinth foob + high-pressure lubrication integrated system, uas zoo cais tawm cov dej ntxeem tau thiab txuas ntxiv ntxiv cov roj lubricating kub kom tsis txhob muaj roj lubrication. 

Thib peb, peb tau optimized lub spherical roller bearing qauv kom sib npaug ntawm cov khoom thauj thoob plaws txhua qhov kev sib tw thiab txo qis kev ntxhov siab hauv zos.
