Tricone Drill Bit Wear Classification Standards thiab Wear Analysis

International Contractor Association Wear Classification Standards

Lub Koom Haum International Contractor Association faib cov laum hnav rau hauv peb pawg: cov hniav hnav, cov kabmob hnav, thiab kev txo qis me ntsis, nrog rau cov qauv tshwj xeeb rau txhua pawg. Cov kev faib tawm no siv rau ntau homtricone laum khoom, suav nrogntxig cov hniav tho khoom,milled hniav tricone khoom, siv hauv roj, roj, thiab dej zoo drilling.

① Hniav Hnav Classification Standard

Cov hniav hnav tau muab faib ua 8 qib, nrog rau cov qauv sib txawv rau cov hniav sib tsoo thiab ntxig cov hniav. Raumilled hniav tricone khoom, kev faib tawm yog nyob ntawm qhov siab ntawm hnav. Yog tias qhov siab hnav tsis pub dhau 1/8 ntawm qhov siab ntawm tus hniav, nws raug cais raws li Qib 1. Yog tias qhov siab hnav yog nyob nruab nrab ntawm 1/8 thiab 2/8 ntawm qhov siab ntawm tus hniav, nws yog Qib 2, thiab lwm yam mus txog qib 8. Cov qauv no tshwj xeeb tshaj yog raumilled hniav tricone khoomthiabluag bitssiv nyob rau hauv mos formations.

Rautungsten carbide ntxig cov hniav, kev faib tawm yog nyob ntawm qhov sib piv ntawm tus naj npawb ntawm cov hniav tawg lossis ploj mus rau tag nrho cov hniav. Yog tias tus naj npawb ntawm cov hniav tawg los yog ploj yog nyob rau hauv 1/8 ntawm tag nrho, nws raug cais raws li Qib 1. Yog tias tus naj npawb ntawm cov hniav tawg los yog ploj yog nyob nruab nrab ntawm 1/8 thiab 2/8 ntawm tag nrho, nws yog Theem 2, thiab ntxiv mus txog Qib 8. Qhov no siv rauTungsten Carbide Tricone Drill Bitthiab lwm yam ntxig hniav tsim.

Hniav hnav yog txhais los ntawm "T", nrog T1 sawv cev rau qib 1 hnav, T2 sawv cev rau qib 2 hnav, thiab lwm yam.

② Bearing Wear Classification Standard

Cov kabmob hnav yog cais raws li qhov sib piv ntawm lub sijhawm siv me ntsis rau cov kabmob tag nrho lub neej (hauv cov xuab moos), nrog rau 8 theem ntawm kev faib tawm. Rau txhua yam ntawmtricone rotary laum khoom,suav nrogdej zoo drilling khoomthiabtricone pob zeb khoom, yog tias lub sijhawm siv mus txog 1/8 ntawm lub neej bearing, nws raug cais raws li Qib 1. Yog tias lub sijhawm siv mus txog 2/8 ntawm lub neej bearing, nws yog Qib 2, thiab lwm yam mus txog rau Qib 8. Thaum lub sijhawm siv poob ntawm ob theem, qib siab dua tau muab.

Cov kabmob hnav yog txhais los ntawm "B", nrog B1 qhia tias 1/8 ntawm cov kabmob tau siv, B2 qhia 2/8, thiab lwm yam. Rau cov kabmob kaw, qhov kev sib khi yog muab faib ua peb theem:

- SE (Kev sib khi zoo)

- SF (Sealing Ineffective)

- SQ (Kev Teeb Meem Teeb Meem)

Cov kev faib tawm no tseem ceeb tshwj xeeb rauTCI laum khoomthiab lwm yam kev ua tau zoo tricone pob zeb khoom.

③Bit Diameter Hnav Sawv Cev

Txhawm rau qhia qhov hnav ntawm qhov me me txoj kab uas hla, "1" sawv cev tias qhov me ntsis khaws nws txoj kab nruab nrab, thaum "0" qhia tias txoj kab uas hla tau txo. Tus nqi ntawm txoj kab uas hla txo yog qhia hauv inches tom qab "0". Piv txwv li, "01/2" txhais tau hais tias qhov me ntsis txoj kab uas hla tau raug txo los ntawm 1/2 nti. Qhov no yog qhov tseem ceeb heev rau kev tswj xyuas qhov kev ua haujlwm zoo drilling hauv ntau daim ntawv thov, suav nrogoil, gas, thiabdej zoo drilling.
