Kev faib tawm los ntawm cov hniav drilling: muaj scraper hom alloy drilling cov hniav, cov menyuam drilling cov hniav thiab cutter drilling hniav.
- Cov yam ntxwv ua haujlwm
1. lub twj tso kua mis slurry tsim los ntawm cov kws tshaj lij kev txuag dej los ntawm Jiangsu University of thev naus laus zis yog qhov siab tshaj plaws hauv Suav teb. Lub impeller muaj kev ua haujlwm siab, thiab ob chav channel impeller tau txais yuav, nrog rau kev txuag hluav taws xob zoo kawg li. Lub twj tso kua mis thiab lub impeller yog ua los ntawm high chromium hlau thiab peev casting txheej txheem, nrog rau saum npoo tiav, zoo hnav tsis kam thiab kev pab lub neej ntev. Lub impeller txais kev ntsuas qhov sib npaug dynamic, nrog kev sib npaug siab thiab ceev ceev. Raws li ntev raws li lub impeller txiaj yog cov khoom me me dua li lub puab kab uas hla ntawm lub laum yeeb nkab, nrog rau cov pob zeb thiab pebbles, nws yuav raug tso tawm, uas tsis txhob rov crushing ntawm cov khoom thiab pebbles. High slag tshem tawm efficiency.
2. Loj torque thiab lifting quab yuam, tshwj xeeb tshaj yog haum rau complex geology xws li gravel, pebble thiab pob zeb;
3. lub manipulator thiab auxiliary winch yog teem rau ntawm gantry thav duab, uas yog yooj yim, txhim khu kev qha thiab txuag zog rau kev tshem tawm thiab txhim kho cov kav dej;
4. Rotary taub hau: qhov tso zis tsis tu ncua, tsis siv neeg kis. Nyob rau hauv qhov sib txawv geological tej yam kev mob, lub variable lub cev muaj zog ntawm lub teb lub taub hau cia li kho cov zis torque thiab tso zis ceev, nrog ib tug high degree ntawm automation, ceev footage ceev thiab siab siv efficiency.
5. Lub ntsuas hluav taws xob thiab lub vijtsam hauv lub cab tso saib cov ntaub ntawv kev ua haujlwm ntawm txhua qhov system hauv lub sijhawm tiag tiag, kom tus neeg teb xov tooj tuaj yeem paub cov haujlwm ua haujlwm txhua lub sijhawm.

- Txheej txheem project
Pump suction rov qab ncig drilling rig. Los ntawm txoj kev khiav dej, cov ntaub ntawv txiav hauv pawg (qhov zoo) yog txuas ntxiv mus rau cov av nkos ntawm ib sab ntawm pawg (zoo) qhov nrog cov av nkos. Hauv cov av nkos, xuab zeb, pob zeb thiab lwm cov ntaub ntawv granular nyob rau hauv qab ntawm lub tank, thiab cov av nkos ntws mus rau hauv pawg (zoo) qhov tsis tu ncua. Ntxiv cov dej theem ntawm pawg qhov. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
3.1. Pile casing yuav tsum tau embedded rau ntawm lub qhov. Lub pob casing yog ua los ntawm cov hlau phaj loj dua 5 hli, thiab nws txoj kab uas hla yuav tsum yog 100 hli loj tshaj qhov tsim pawg (zoo) qhov taub. Qhov ntev ntawm pawg casing nyob ntawm qhov xwm txheej geological. Cov ntug hauv qab ntawm pawg casing yuav tsum tau muab faus rau hauv cov av mus tas li thiab tshaj cov txheej txheem rov qab.
3.2. Yog hais tias lub backfill tob dhau lawm thiab lub excavator lossis phau ntawv ua haujlwm tsis tuaj yeem ua haujlwm, tus neeg siv tuaj yeem tshwj xeeb ua ib lub thoob laum me ntsis thiab kho nws ntawm lub laum txhawm rau khawb qhov. Qhov tob feem ntau tsis ntau tshaj 10m. Raws li qhov tshwm sim. Tsis txhob tawg.
3.3. Lub peev xwm excavation ntawm lub qhov av nkos yuav tsum ntau dua li qhov ntim ntawm pawg. Nws yog qhov zoo dua los siv cov duab plaub, uas tuaj yeem ncua lub sijhawm thiab ceev ntawm av nkos reflux nyob rau hauv pawg, thiab cov khoom siv granular tuaj yeem khom mus rau qhov siab tshaj plaws.
