Kutsogola kwaukadaulo wa Hydraulic ndi Madzi Ogwiritsa Ntchito DTH Drilling Technology.

1. Ubwino wa Hydraulic Rock Drills

① High Hydraulic Pressure: Nthawi zambiri kuyambira 10 mpaka 25 MPa, yokhala ndi malire apamwamba. Izi ndizokwera kangapo mpaka kambirimbiri kuposa kukakamiza kwa pneumatic.

② Mphamvu Zotulutsa Zambiri: Nthawi zambiri pakati pa 5 mpaka 20 kW. Mitundu ina, monga COP4050 ya ATLAS ndi HL2000 ya TAMROCK, imafika 40 kW, pomwe HL4000 imakwanitsa mpaka 70 kW.

③ Kuthamanga Mofulumira Kubowola: Nthawi zambiri amakwaniritsa kukumba kwa 1-3 m / min.

④ Kuchita Bwino Kwambiri: Kuchita bwino kwa ma hydraulic rock kubowola okha kumatha kufika 50%, ndipo mapampu a hydraulic ndi othandiza kwambiri kuposa ma compressor a mpweya. Chifukwa chake, kugwiritsa ntchito mphamvu zonse ndikokwera kwambiri kuposa makina obowola miyala a pneumatic.

2. Kuipa kwa Hydraulic Rock Drills

① Kutayika kwa Mphamvu Yotumizira: Popeza kuti kubowola kwa thanthwe kuli pamwamba pa ndodo yobowola, kutaya mphamvu kwapang'onopang'ono kumawonjezeka ndikuya kwa dzenje, zomwe zimapangitsa kuti liwiro la kubowola lichepe.

② High Drill Rod Wear: Pamene mphamvu yobowola miyala ya hydraulic ikuwonjezeka, kupsinjika pa ndodo yobowola kumachulukiranso, zomwe zimapangitsa kuwonongeka kwakukulu. Ngakhale matekinoloje monga kubowola casing kwa Atlas Copco amathandizira kuchepetsa kupsinjika, amachulukitsa ndalama ndikulephera kuthetsa vutolo, potero amachepetsa mphamvu yakubowola. Mwachitsanzo, pomwe mphamvu ya COP4050 ndi 40 kW, 30 kW yokha ndiyomwe imagwiritsidwa ntchito pobowola dzenje lakuya kuti achepetse kupsinjika pazida.

③Kupatuka kwa Borehole: Ndodo zobowola zimapirira mphamvu zonse ndi torque, zomwe zimapangitsa kupindika ndi kupindika, zomwe zimachepetsa kulondola kwa borehole.

3. Ubwino waPansi Pabowo (DTH)Zobowola

① Palibe Kutayika Kwa Mphamvu Zotumiza: Nyundo imakhudza mwachindunjikubowola pang'ono, kuthetsa kufunikira kwa kusintha kwa mphamvu ya mphamvu kudzera pa ndodo yobowola, kuonetsetsa kuti akuthamanga mofulumira mosasamala za kuya.

② Boreholes Zowongoka: Ndodo yobowola imakhala yolimba kwambiri, simakhudzidwa ndi mphamvu, ndipo imatumiza torque yokhayokha ndi kupanikizika kochepa kwa axial. Izi zimalepheretsa kupindika ndi kupindika, kuonetsetsa kuti zibowo zowongoka komanso zosalala. Kubowola kwa DTH kumachita bwino m'mipangidwe yosweka, strata yokhazikika, kapena kulimba kwamiyala kosiyanasiyana.

③ Kuchotsa Mwachangu Zinyalala: Sing'anga yamagetsi imawirikiza kawiri ngati sing'anga, kuyeretsa bwino chibowo ndikupewa kubowola mopitilira muyeso.

④ Phokoso Lochepa: Popeza kukhudzidwa kumachitika pansi pa borehole, phokoso ndilotsika kwambiri kuposakubowola nyundo zapamwamba.

⑤ Kugwiritsa Ntchito Kwakukulu: Kupatula mawonekedwe ofewa kwambiri, zobowola za DTH zimagwira ntchito bwino mumitundu yonse yamiyala, kupitilira kubowola kwa miyala ya nyundo yapamwamba m'mimba mwake ndi kuya kwake.

Poganizira zaubwinowu, kubowola kwa DTH kumawonedwa ngati njira yabwino kwambiri, pomwe 90% ya miyala yaku Britain imagwiritsa ntchito njirayi.

4. Kuipa kwa Pneumatic DTH Drills

① Kutsika Kwambiri ndi Mphamvu: Chomwe chimayambira pakubowola kwa pneumatic DTH ndi kutsika kwawo kwa mpweya ndi mphamvu zotulutsa, zomwe zimapangitsa kuti pakhale kuthamanga pang'onopang'ono. Ngakhale kupita patsogolo kwakweza mphamvu ya mpweya kufika pa 2.5 MPa, izi zikadali zotsika kwambiri ndi mphamvu ya hydraulic yobowola miyala. Kuphatikiza apo, ma compressor apamwamba kwambiri ndi okwera mtengo, amafunikira ma drive amphamvu kwambiri, amatulutsa phokoso lochulukirapo, ndipo amataya mphamvu kwambiri m'malo okwera kwambiri.

② Kugwiritsa Ntchito Mphamvu Zochepa: Kubowola kwa Pneumatic DTH kumawononga mphamvu zochulukirapo katatu pa mita yobowoleredwa kuposa ma hydraulic rock kubowola.

5. Kugwiritsa ntchito HydraulicDTH Nyundo

Kuphatikizira ubwino wa ma hydraulic rock drill (kuthamanga kwambiri ndi kuyendetsa bwino) ndi DTH (boreholes zowongoka), Hausherr waku Germany adapanga "Rapid Hydraulic DTH Drill" koyambirira kwa 1990s. Njira zake zonse zozungulira komanso zomwe zimakhudzidwa zimayendetsedwa ndi ma hydraulically. Nyundoyo imakhala ndi mizere iwiri yamafuta kuti iperekedwe ndi kubweza. Kubowola kofulumira kumapezeka m'madiameter atatu: 90 mm, 115 mm, ndi 150 mm, oyenera mabowo okhala ndi ma diameter a 100-125 mm, 127-156 mm, ndi 168-230 mm, motsatana.

Mayeso oyerekeza a HBM80S HBM80S pneumatic DTH kubowola kwa Rapid ndi Hausher adawonetsa kuti, pamabowo ofanana (125 mm) ndi kuya (36 m), Rapid idawonetsa zabwino zambiri zachuma ndi mphamvu ya injini yotsika, kugwiritsa ntchito mafuta, komanso kugwiritsa ntchito mafuta opaka mafuta a 0.46, 0.46, 0.46, ndi ulemu

6. Kugwiritsa Ntchito Nyundo Zopangira Madzi a Hydraulic

LKAB yaku Sweden ndi gulu lake la G-Drill adapanga "Wassara Water-Powered DTH Hammer" kumapeto kwa zaka za m'ma 1980. Pogwiritsa ntchito madzi a mgodi osefedwa monga sing'anga, imagwira ntchito mothamanga kwa 18-20 MPa ndi kuthamanga kwa 200-300 L / min. Pobowola liwiro la 850 mm/min, imaposa nyundo za pneumatic (nthawi zambiri 320 mm/min).

Nyundo ya Wassara yawonetsa kuchita bwino kwambiri, monga kuchepetsa kupotokola kwa borehole ndi theka ndikuwonjezera zokolola ndi 86% m'migodi ya LKAB. Mapulogalamuwa akuphatikiza kukumba pansi pa subway ku New York ndi kubowola kwa geothermal ku Switzerland, komwe adamaliza chitsime cha 599.8 m m'masiku 5, poyerekeza ndi milungu itatu yobowola mwachizolowezi.

7. Kufananiza: Hydraulic Water-Powered vs. Hydraulic Fluid-Driven Hammers

Nyundo Zogwiritsa Ntchito Madzi: Gwiritsani ntchito kuthamanga kwa madzi osasunthika, kuchita bwino kwambiri komanso kuthamanga kwambiri pakubowola, oyenera kugwiritsa ntchito migodi.

Nyundo Zoyendetsedwa ndi Madzi: Gwiritsani ntchito mphamvu yamadzi yosunthika ndipo nthawi zambiri imangobowola m'matanthwe omwe ali ndi mphamvu zochepa (0.5-4 MPa) ndikuchita bwino (

8. Mapeto

Ma hydraulic ndi madziNyundo za DTHphatikizani ubwino wa nyundo zobowolera nyundo zapamwamba ndi nyundo za DTH za pneumatic, zopatsa mphamvu zochepa, kuthamanga kwambiri pobowola, ndi zibowo zowongoka. Njira yolumikizana yopangira mphamvu ndi kuwotcha imapangitsa nyundo zoyendetsedwa ndi madzi kukhala zolimbikitsa kwambiri pakukula kwamtsogolo.
