Lub core laum (CB) yog ib hom kev xyaum tshwj xeeb uas tso cai rau cov pob zeb cores tawg los ntawm lub rauj laum los yog auger me ntsis los ntawm kev txiav lub nplhaib - zoo li zawj.
Vim muaj qhov sib txawv ntawm lub nplhaib welded, cov tub ntxhais xyaum tau muab faib ua plaub hom: CB-I, CB-II, CB-III, thiab CB-IV.qhov drilling tshuab nqe
Tube Drill
Rau qhov nyuaj bedrock strata, loj pob zeb txheej, thiab tawv permafrost khaubncaws sab nraud povtseg, ncaj drilling nrog auger los yog rotary drilling khoom yog nyuaj. Tube laum khoom yuav tsum tau ua ke nrog auger thiab xuab zeb -dredging khoom. Lawv muab faib ua cov tub ntxhais - noj cov raj laum cov khoom thiab tsis yog - tub ntxhais - noj cov raj laum khoom. Nyob ntawm cov strata tau drilled, lawv tau muab faib ntxiv rau hauv kev txiav cov hniav tho cov khoom tsim nyog rau cov huab cua puag ncig thiab cov txheej txheem permafrost, thiab cov menyuam lub khob hliav qab raj laum cov khoom tsim nyog rau cov tawv tawv tawv. Cov tub ntxhais - coj lub raj laum me ntsis muaj cov qauv hauv qab no thiab cov qauv kev ua haujlwm: Lub thoob lub cev muaj lub raj sab hauv thiab lub raj sab nraud. Lub raj sab nraud yog welded nrog lub ntsiab txiav cov hniav, thiab lub raj sab hauv yog welded nrog cov hniav ntuag. Qhov qis kawg ntawm lub raj sab hauv yog nruab nrog hinges los txhawb lub pob zeb core.qhov drilling tshuab nqe
Qeb
Rotary drilling rig, me me teb drilling rig, piling tshuab. Thaum lub sij hawm drilling, cov tub ntxhais raug thawb qhib los ntawm lub pob khawm thiab nkag mus rau hauv cov yeeb nkab. Thaum lub laum yog rub tawm, lub pob khawm, nyob rau hauv nws tus kheej qhov hnyav, tseem nyob rau hauv txoj hauj lwm kab rov tav, sealing cov tub ntxhais hauv cov yeeb nkab puab thiab nqa tawm ntawm lub qhov. Tsis yog- corering annular core laum ntsis qauv cov yam ntxwv thiab cov hauv paus ntsiab lus ua haujlwm: Txiav cov hniav ncaj qha mus rau sab qis ntawm lub cev laum. Thaum lub sij hawm drilling, lub corer thawj zaug xyaum qhov tsim nyob rau hauv ib tug annular puab rau hauv ib tug cylindrical zoo, thiab ces lub auger laum ntsis yog txo kom tawg lub voj voog cores nyob rau hauv fragments, uas yog ces retrieved siv xuab zeb scoop.
Shandong Liqiang Machinery tus phooj ywg ceeb toom ntawm kev ua haujlwm ceev faj: Lub laum tuaj yeem rub tawm thaum lub qhov puv, tab sis nws yuav tsum tau ua kom qeeb. Vim tias qhov laum me me no muaj qhov txiav sab hauv, nws tuaj yeem khaws cov tub ntxhais lossis pob zeb loj txawm tias tsis muaj corer. Yog tias nws tsis tuaj yeem rov qab tau, qhov no yog qhov qub, vim nws lub hom phiaj tseem ceeb yog los tsim qhov chaw txiav dawb rau kev rov qab ntxiv siv cov xuab zeb los yog auger laum me ntsis.qhov drilling tshuab nqe
