"Vim li cas peb thiaj hloov cov kav dej tho dua?"
Tus thawj saib xyuas ntawm qhov chaw tau saib ntawm qhov hnav xov txuas ntawm lub rig hauv pem teb.
"Peb nyuam qhuav hloov lawv peb lub hlis dhau los."
Drilling engineer sighed. "Kev qaug zog tawg. Abrasion. Huab cua to. Peb poob lub zog ua ntej nws txawm mus txog rauj."
Yog tias qhov kev sib tham no zoo li paub, koj tsis nyob ib leeg.
Thoob plaws lub ntiaj teb mining thiab kev tsim kho tej yaam num,nqes - lub - qhov (DTH) drillingCov neeg cog lus ntsib tib tus nqi zais tus neeg tsav tsheb: ua ntej lub sijhawm xyaum ua cov yeeb nkab tsis ua haujlwm. Tsis yog rauj. Tsis yog me ntsis. Tab sis cov yeeb nkab - qaum ntawm txoj hlua xyaum.
Nyob rau hauv siab - ib puag ncig siab, qhov twg compressed cua powers systems xws li ib tug Down- lub - qhov drilling teeb, kev ua tau zoo poob compound sai. Txo airflow, xov deformation, micro- tawg, thiab misalignment tag nrho cov txhais ua:
- Kev hloov ntau zaus
- Nce downtime
- Txo tus nqi nkag
- Txo rov qab los ntawm cov cuab yeej siv peev
Lo lus nug tiag tiag tsis yog tias koj tuaj yeem txo cov nqi hloov pauv.
Lo lus nug yog:Puas yog koj cov kav dej laum tau tsim kom muaj sia nyob cov pob zeb nyuaj, siab siab, thiab lub voj voog siab qaug zog?
Nyob rau hauv tsab xov xwm no, peb mam li qhia yuav ua li cas optimizedDTH laum yeeb nkabKev tsim qauv tuaj yeem txo cov nqi hloov pauv mus txog 30%, txhawb nqa los ntawm cov qauv kev tsim vaj tsev, cov ntaub ntawv tshawb fawb, thiab kev tshawb fawb kev lag luam.
Tus nqi zais ntawm Standard DTH Laum Pipes
Ntau tus neeg cog lus soj ntsuam cov kav dej tsuas yog ntawm tus nqi pib yuav khoom. Tab sis tag nrho cov nqi ntawm cov tswv cuab (TCO) qhia ib zaj dab neeg sib txawv.
Qhov Chaw Hloov Cov Nqi Tiag Los Ntawm
- Kev qaug zog tawg ntawm xov cag
- Abrasive hnav nyob rau hauv hard pob zeb formations
- Cua nkag ntawm cov pob qij txha
- Khoov kev ntxhov siab los ntawm misalignment
- Corrosion nyob rau hauv high noo noo ib puag ncig
Raws li kev tshawb fawb qaug zog hais txog kev tshawb fawb cov ntaub ntawv engineering (saib cov hauv qab no), cyclic kev ntxhov siab tsis ua haujlwm yog lub luag haujlwm rau feem pua ntawm kev xyaum ua haujlwm hauv kev ua haujlwm tsuas.
Thaum drill rods tsis muajsuperior tsis kam rau abrasion thiab qaug zog, lawv ua tsis tau ntev ua ntej lawv txoj kev pab cuam lub neej.
Kev ua tau zoo ntawm LEANOMS DTH Laum Pipe suav nrog:
1. Superior Fatigue Strength
Lub zog qaug zog txiav txim seb muaj pes tsawg lub voj voog kev ntxhov siab ib lub yeeb nkab tuaj yeem tiv taus ua ntej microscopic tawg tsim thiab nthuav tawm.
LEANOMS DTH laum rods yog engineered nrog:
- High-qib alloy steel
- Tswj cov txheej txheem kho cua sov
- Optimized phab ntsa thickness faib
- Reinforced xov hauv paus geometry
Qhov no ua rauDrill rods nrog superior tsis kam rau puas thiab qaug zog, muaj peev xwm tuav:
- Siab -rauj cuam tshuamkev vibration
- Rov ua dua torsional kev nyuaj siab
- Sib sib zog nqus- qhov drilling voj voog
Vim Li Cas Nws Tseem Ceeb
Kev qaug zog tsis ua haujlwm feem ntau pib pom tsis pom. Micro- cracks nthuav dav hauv kev ntxhov siab kom txog thaum muaj kev puas tsuaj tam sim ntawd. Los ntawm kev txhim kho cov khoom siv nplej thiab qhov tawv tawv, lub neej qaug zog tuaj yeem nce ntxiv.
Kev tshawb fawb metallurgy tshawb fawb qhia tau hais tias qhov ua kom zoo tshaj qhov cua sov-kho hlau alloy tuaj yeem txhim kho kev qaug zog los ntawm 20-40% piv rau qhov sib npaug tsis tau kho.
Qhov no txhais ncaj qha mus rau hauv cov yeeb nkab tsawg dua thiab cov nqi qis dua.
2. Kev tso zis ntau tshaj plaws
DTH drilling efficiency nyob ntawm lub zog hloov. Cov cua compressed yuav tsum taug kev los ntawm compressor → yeeb nkab → rauj yam tsis poob.
Tsis zoo machined internal diameters txo airflow efficiency.
LEANOMS laum yeeb nkab yog tsim raws li:
- DTH rodskom ntseeg tau tias qhov zoo tshaj plaws airflow thiab cuttings tshem tawm
- Smooth internal bore nto
- Tight - kam rau ua xov sealing
- Siab- poob qis qis kev sib txuas geometry
Qhov tshwm sim:
- Lub zog rauj cuam tshuam lub zog
- Kev nkag siab ntau dua
- Txo compressor load
- Txhim kho roj efficiency
Thaum lub zog poob qis, qhov drilling ua tau zoo sib xws -tshwj xeeb tshaj yog nyob rau hauv qhov tob, loj - txoj kab uas hla.
3. Technically Advanced Manufacturing
Niaj hnub nimno drilling xav tau precision.
LEANOMS siv:
- CNC precision threading
- Kev sib txhuam welding technology
- Tsis yog -kev kuaj kev puas tsuaj (NDT)
- Dynamic straightness soj ntsuam
Cov txheej txheem no tsim:
- Precision DTH laum rods rau lub qhov ncajdrilling hauv kev tsim kho
- Txhim kho concentricity
- Txo kev vibration
- Qis khoov kev nyuaj siab
Tsis ncaj ncaj nce torque fluctuation thiab accelerates xov hnav. Precision engineering ncaj qha txo cov voj voog txij nkawm.
Cov no yog tiag tiagTsawg-kev tu DTH xyaum hlua cov khoom, tsim los txo kev cuam tshuam kev pabcuam.
4. Hard Rock Optimized Structure
Hard limestone, granite, thiab basalt ua rau muaj kev puas tsuaj loj heev.
Hauv cov txheej txheem zoo li no, cov kav dej yuav tsum yog:
- tuab-walled tab sis hnyav- sib npaug
- Nto- hardened ntawm threads
- Resistant torsional overload
Raws li cov ntawv thov drilling loj tuajcov mines ntxaumthiab infrastructure tunneling, thov rauDrill rods tsim rau siab tshaj plaws drilling efficiency nyob rau hauv lub pob zeb nyuajtxuas ntxiv mus.
Cov ntaub ntawv kev lag luam los ntawm cov khoom siv mining thoob ntiaj teb kev lag luam qhia tau tias muaj kev nce siab ntawm - lub zog laum txoj hlua rau kev sib sib zog nqus thiab ntau txoj haujlwm drilling.
