Tej Yam Koj Yuav Tsum Paub Txog PDC Drill Bits

Polycrystalline pob zeb diamond compact (PDC) yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws nyob rau hauv lub ntiaj teb no, uas nyuaj tshaj li tungsten carbide. Txawm hais tias PDC muaj zog txaus los siv rau hauv kev lag luam niaj hnub, lawv kim heev. Tungsten carbide zoo dua li cov khoom siv PDC kev lag luam thaum cov pob zeb tsis tawv. Tab sis PDC laum cov khoom, tau kawg, muaj lawv qhov zoo vim tias lawv tau nrov hauv kev tsim kho mining.

PDC laum ntsis yog dab tsi?

Raws li peb txhua tus paub, tungsten carbide nyees khawm yog siv los ntxig rau hauv lub cev laum los tsim ib lub laum me ntsis. PDC laum khoom muaj PDC cutters rau lawv. PDC cutters yog ua los ntawm tungsten carbide PDC substrates thiab PDC txheej nyob rau hauv ib puag ncig ntawm kev kub siab thiab kub. Thawj qhov kev tsim khoom ntawm PDC laum khoom tau tshwm sim hauv xyoo 1976. Tom qab ntawd, lawv tau dhau los ua ntau thiab nrov hauv ntau qhov kev lag luam drilling.

PDC laum me ntsis ua li cas?

PDC laum me ntsis yog los ntawm tungsten carbide PDC substrates thiab PDC txheej. PDC substrates yog los ntawm cov hmoov zoo tungsten carbide hmoov, muaj kev sib tov, milling, nias, thiab sintering. PDC substrates yuav tsum tau ua ke nrog PDC txheej. Nrog cov catalyst ntawm cobalt alloy nyob rau hauv qhov kub thiab txias siab, uas yuav pab tau cov pob zeb diamond thiab carbide, PDC cutter tuaj yeem tawv thiab ruaj khov. Thaum lawv txias, tungsten carbide shrinks 2.5 npaug sai dua PDC txheej. Nyob rau hauv ib puag ncig ntawm qhov kub siab dua, PDC cutters yuav raug forged rau hauv cov khoom xyaum.

Kev siv ntawm PDC laum khoom

Niaj hnub no, PDC laum khoom feem ntau yog siv rau hauv cov xwm txheej hauv qab no:

1. Kev tshawb nrhiav geological

PDC laum cov khoom tsim nyog rau kev tshawb nrhiav geological ntawm cov pob zeb mos thiab nruab nrab hardness vim lawv cov hardness siab.

2. Ntawm qhov chaw ua hluav taws xob

Thaum PDC laum cov khoom siv rau hauv coalfield, lawv tau siv rau drilling thiab mining thee seam. PDC laum khoom ua haujlwm siab.

3. Kev tshawb nrhiav roj av

PDC laum cov khoom siv kuj tseem siv tau rau kev tshawb nrhiav roj av rau drilling hauv cov roj thiab roj. Hom PDC laum no yog ib txwm kim tshaj plaws.

Qhov zoo ntawm PDC laum khoom

1. Kev tiv thaiv siab rau kev cuam tshuam;

2. Lub neej ua haujlwm ntev dua;

3. Tsis yooj yim rau kev puas tsuaj lossis poob tawm;

4. Txuag cov neeg siv khoom tus nqi;

5. Kev ua haujlwm siab dua.

Yog tias koj txaus siab rau PDC cutters thiab xav tau cov ntaub ntawv thiab cov ntsiab lus ntxiv, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL rau hauv qab ntawm nplooj ntawv.
