Impregnated Laum Ntsis
Tsim kom muaj ROP siab dua hauv kev sib sib zog nqus thiab sib zog ua haujlwm, PDC xyaum me ntsis ib txwm xyaum los ntawm hauv av mus rau hauv qab ncaj qha nrog tsawg lossis txawm tias ib zaug khiav, txuag ntau qhov kev siv sijhawm thiab tus nqi.
Sib txawv los ntawm tricone ntsis, PDC laum me ntsis khiav nrog WOB qis dua tab sis siab dua RPM, yog li nws feem ntau ua haujlwm nrog lub tshuab qis qis kom tuaj yeem nrawm nrawm.
Kev ua tau zoo ntawm PDC laum me ntsis nyob ntawm ntau ntawm PDC cov tshuab txiav, peb muab cov kev daws teeb meem tshwj xeeb rau qhov xav tau tshwj xeeb ntawm cov ntawv sib txawv.
Taw qhia:
Impregnated Pob Zeb Diamond Me muaj Cylindrical toothed hniav uas muaj qhov nkag mus siab dua nyob rau hauv tawv thiab ntom tawv yas sib cuam tshuam kev tsim.
Nta
1.Targeted tsim:Nws muaj qhov tshwj xeeb tsim rau siab ua kom muaj zog thiab ua kom tawg. Nws yog qhov tsim nyog rau denser shale thiab argillaceous sandstone, thiab quartz sandstone nrog siab abrasiveness, av nkos thiab sandstone interlaced strata yog qhov tsim nyog.
2. Cov cim puab sab hauv tshwj xeeb: Qhov tshwj xeeb geometry thiab kev teeb tsa sab hauv lub khob hliav me ntsis txhim kho qhov kev ua haujlwm ntawm qhov nruab nrab ntawm qhov laum me ntsis txhawm rau txuas ntxiv lub neej tag nrho ntawm cov laum me ntsis.
Tshuab
1.Qhov tshwj xeeb matrix formula: Cov mis ntawm matrix hmoov nrog kev ywj pheej ntawm cov cuab yeej cuab tam txoj cai thiab kev siv tshuab sintering siab tau ua rau cov khoom siv dag zog ntawm matrix mus txog qib thoob ntiaj teb.
2. Dav thiab sib sib zog nqus ntws tsim channel: Lub dav radial dav thiab sib sib zog nqus ntws yog muaj txiaj ntsig zoo rau kev ntxuav thiab thauj mus los ntawm kev txiav thiab tiv thaiv me ntsis pob.
