Cov yam ntxwv cuam tshuam rau DTH Bit Efficiency

DTH (Down-The-Hole) me ntsis yog hais txog cov cuab yeej tshwj xeeb drilling siv hauv kev tsuas, kev tsim kho, thiab roj thiab roj kev lag luam. Nws yog tsim los txuas rau DTH rauj thiab siv hauv kev ua haujlwm hauv qhov chaw drilling.

Ntxiv rau qhov kev xaiv kom raug ntawm cov qib cemented carbide, qhov ua tau zoo ntawm DTH laum tseem cuam tshuam los ntawm ntau yam, qhov kev xyaum ua haujlwm tuaj yeem pom tau los ntawm kev soj ntsuam kom zoo. Cov duab ntawm lub laum me ntsis txawv, thiab seem ntawm lub qhov tawg tau txais thaum lub laum yog qhov sib txawv.

1. Drill puab

Cov duab ntawm lub laum me ntsis ncaj qha cuam tshuam rau ntu ntawm lub qhov tawg. Lub qhov blast qhov seem ntawm feem ntau xyaum me ntsis yog polygonal, tsis puag ncig. Yog li ntawd, lub polygonal seem yog tsim vim qhov sib txawv ntawm qhov xyaum me ntsis mus rau ib sab ntawm lub qhov tawg thaum nws tig raws nws axis. Thaum lub sij hawm drilling txheej txheem, lub laum pas nrig tsis tig ntawm lub axis ruaj tab sis oscillates dawb hauv lub borehole.

2. Pob zeb khoom

Lub pob zeb cov khoom uas cuam tshuam rau qhov nrawm me ntsis yog viscosity, hardness, thiab elasticity. Qhov nplaum ntawm lub pob zeb yog lub peev xwm ntawm lub pob zeb los tiv thaiv kev tawg mus rau hauv me me. Cov khoom ntawm pob zeb muaj feem xyuam rau qhov muaj pes tsawg leeg thiab muaj pes tsawg leeg ntawm cov pob zeb; qhov me me thiab cov duab ntawm cov khoom; thiab qhov ntau, muaj pes tsawg leeg, thiab noo noo cov ntsiab lus ntawm cov cement. Cov pob zeb nruj thiab homogeneous muaj tib viscosity nyob rau hauv tag nrho cov lus qhia, thiab heterogeneous los yog txheej pob zeb muaj viscosity sib txawv nyob rau hauv tag nrho cov lus qhia. Lub hardness ntawm pob zeb, zoo li lub viscosity, yog txiav txim los ntawm kev sib txuas quab yuam ntawm cov pob zeb hais. Txawm li cas los xij, lub hardness ntawm pob zeb yog lub peev xwm los tiv thaiv cov cuab yeej ntse nkag mus rau nws. Lub elasticity ntawm pob zeb hais txog nws lub peev xwm los kho nws cov duab qub thiab ntim tom qab lub zog sab nraud ua rau nws ploj mus. Tag nrho cov pob zeb yog elastic. Lub elasticity ntawm pob zeb muaj kev cuam tshuam loj heev rau kev cuam tshuam ntawm kev xyaum me ntsis.

ZZBETTER Drill Bit Factory yog ib lub tuam txhab koom nrog kev tshawb fawb thiab kev muag khoom ntawm pob zeb drilling cuab yeej. ZZBETTER Drill Bit Factory tsuas yog tsim thiab muag ZZBETTER series down-the-hole laum khoom, laum kav, thiab down-the-qhov-qhov drilling rigs, thiab tsim ntau yam pob zeb drilling cuab yeej, mining machinery khoom accessories, impactors, thiab lwm yam. thiab DTH rigs thiab DTH khoom nrog cov khoom tsim tshwj xeeb.
