Carbide Inserts Wear Failure thiab Solutions

Cov tungsten carbide hnav inserts yog siv los txiav cov hlau casing thiab ntsaws, tshem tawm cov khib nyiab hauv qab thiab tiv thaiv qhov chaw ntawm cov cuab yeej downhole. Ntau hom tungsten carbide hnav qhov chaw, xws li cov duab plaub, square, puag ncig, ib nrab puag ncig, thiab oval, tuaj yeem tsim. Cov inserts no xyuas kom meej tias lub brazing alloy muaj peev xwm nkag mus rau qhov chaw nruab nrab ntawm cov hniav thiab cov ntxig, muab cov ntawv cog lus ruaj ntseg uas koj tuaj yeem ntseeg tau. Lawv tau tsim los siv nrog peb cov pas nrig sib xyaw kom muab cov khoom zoo.

Vim li cas Carbide inserts Wear Fail?

Cov cuab yeej hnav piav qhia txog qhov ua tsis tiav ntawm cov cuab yeej txiav vim kev ua haujlwm tsis tu ncua. Nws yog ib lo lus uas feem ntau cuam tshuam nrog cov cuab yeej siv piv txwv ntawm kev xa, milling, drilling thiab lwm yam kev ua haujlwm machining qhov twg chips tau ua. Peb kuj tuaj yeem hais tias "Peb tau pib nrog kev txiav tawm tshiab thiab thaum pib ntawm kev ua haujlwm txhua yam ua haujlwm zoo. Tom qab qee lub sijhawm, tej yam pib hloov. Tolerances tau tawm, nto tiav tsis zoo, vibrations tshwm sim, ntau lub zog tau siv thiab ntau yam ntxiv uas tuaj yeem tshwm sim thaum txiav ntug tau mus txog qhov kawg ".

Peb tuaj yeem ntsuas dab tsi los tiv thaiv qhov hnav tawm ntawm peb qhov kev txiav?

Siv qhov txiav ceev ntawm Vc = 0m / min lossis tsis siv cov cuab yeej. Peb tuaj yeem cuam tshuam tus cwj pwm coj los ntawm kev hloov cov ntaub ntawv machining. Muaj kev sib raug zoo ntawm ib yam khoom siv thiab hnav mechanisms. Lub hom phiaj yog kom muaj kev kwv yees Flank Hnav. Kev hnav tsis tu ncua thiab tsis hnav lub ncov ua rau peb xav tau tus cwj pwm. Random hnav yog qhov tsis zoo thiab ua rau peb tsis tuaj yeem ua tiav cov khoom lag luam (ntim). Ib qho lus zoo los ntawm tus kws qhia ntawv Asmeskas paub txog kev txiav hlau: "Kev paub txog qhov teeb meem tsuas yog ib nrab ntawm kev sib ntaus sib tua!" -Mr. Ron D. Davies"

Nov yog ib qho piv txwv ntawm Insert Wear Failure: Notching

Ua rau

Notching yog tshwm sim thaum lub nto ntawm lub workpiece yog ib qho nyuaj los yog ntau abrasive tshaj cov khoom ntxiv nyob rau hauv, xws li. nto hardening los ntawm yav dhau los txiav, forged los yog cam khwb cia nto nrog nto scale. Qhov no ua rau cov ntxig rau hnav sai dua nyob rau hauv qhov chaw txiav. Kev ntxhov siab hauv cheeb tsam kuj tuaj yeem ua rau muaj kev cuam tshuam. Raws li qhov tshwm sim ntawm kev ntxhov siab nyob rau ntawm ntug txiav - thiab tsis muaj tib yam tom qab txiav ntug - qhov ntxig tshwj xeeb tshwj xeeb ntawm qhov tob ntawm txoj kab txiav. Kev cuam tshuam ntawm txhua yam, xws li nyuaj micro suav nrog hauv cov khoom siv ua haujlwm lossis kev cuam tshuam me ntsis, tuaj yeem ua rau muaj kev cuam tshuam.

Dab tsi yuav tsum tau pom

•Notching lossis chipping ntawm qhov tob ntawm qhov chaw txiav ntawm qhov ntxig.

Thaum twg los tau

• Cov khoom siv nrog cov nplai (cov ntaub ntawv pov tseg lossis forged) lossis oxidation.

• Lim cov ntaub ntawv hardening.

Kev Cai Kho

• Txo qhov pub thiab sib txawv qhov tob ntawm kev txiav thaum siv ntau qhov kev hla.

• Ua kom nrawm dua yog tias ua kom lub siab kub siab (qhov no yuav ua rau ntau dua flank hnav).

• Xaiv cov qib siab carbide.

•Siv lub chip breaker tsim los rau siab pub.

• Tiv thaiv cov ntug tsim, tshwj xeeb tshaj yog nyob rau hauv stainless thiab siab temp alloys.

• Xaiv lub kaum sab xis me me.

•Yog tias ua tau, siv cov khoom siv puag ncig.

ZZBetter Tshuag muaj ntau yam kev xaiv ntawm hnav tiv thaiv inserts. Cov ntawv ntxig muaj nyob rau hauv ntau yam qauv thiab cov duab, nrog rau trapezoidal. Thaum ua ntawv thov rau ib lub cuab yeej, lawv tuaj yeem ua tiav nrog cov hlau txau hmoov lossis cov pas nrig sib xyaw kom muaj qhov hnav tsis kam ua kom tau raws li koj daim ntawv thov xav tau.

Yog tias koj tab tom nrhiav rau cov khoom lag luam zoo uas muab kev hnav zoo thiab cuam tshuam rau peb muaj qhov koj tab tom nrhiav. Peb tau coj cov kev tiv thaiv kev tiv thaiv kev lag luam mus rau qib tom ntej nrog siab toughness, ntau qhov ntev, thiab lub Hoobkas ncaj qha.
