Kumvetsetsa Mfundo Zamakina za DTH Hammers ndi Bits

Pobowola m'miyala yolimba,DTH (Down the Hole) nyundo ndi zobowola amagwira ntchito yofunika kwambiri pobowola. Zida zimenezi zapangidwa kuti zithyole bwino miyala yolimba ndikupereka njira zotsika mtengo zogwiritsira ntchito pobowola. Mu blog iyi, tiwona mozama momwenyundo zapansi-pabowo ndi zobowolantchito ndi kufunika kwawo mu makampani kubowola.

 Nyundo yapansi-pabowo ndi bitigwirani ntchito limodzi kuti mupange makina obowola amphamvu.Nyundo ya DTH ndi chida champhamvu chomwe chimagwiritsidwa ntchito pobowola mwamphamvu pobowola, potero amaphwanya mapangidwe a miyala. Chowotchacho chimamangiriridwa pamwamba pa chingwe chobowola, ndipo chikagunda pobowola, chimapanga mphamvu zambiri zomwe zimatumizidwa ku thanthwe. Mphamvu yamphamvu imeneyi imathandizira pobowola kulowa mu thanthwe ndikupanga pobowola.

Zowononga pansi pa dzenje zimagwira ntchito popanikiza mpweya kapena madzi ena obowola (monga madzi kapena matope) kuti azipatsa mphamvu mphamvu. Pamene mpweya woponderezedwa kapena madzimadzi akuyenda pansi pa chingwe chobowola, umalowa m'chitsanzo ndi kupanga mikwingwirima yothamanga kwambiri. Mikwingwirima iyi imachita molunjika pabowolo, kulola kuti iphwanye ndi kuphwanya mapangidwe a miyala. Kuchita bwino kwanyundo yapansi-pabowoyagona mu mphamvu yake yopereka mphamvu zokhazikika komanso zogwira ntchito kwambiri, zomwe zimapangitsa kuti zikhale zoyenera pobowola zovuta.

Kubowola, kumbali ina, ndi gawo lofunikira lomwe limalumikizana mwachindunji ndi mapangidwe a miyala. Amapangidwa ndi zinthu zosagwira ntchito monga ma carbide kuti apirire kuwonongeka ndi kung'ambika kwa miyala. Chobowolacho chimakhala ndi mabatani angapo kapena mano omwe amayikidwa mosamala kuti apange chodulira akamenyedwa ndi nyundo. Kudula uku, kuphatikiza ndi mphamvu ya nyundo, kumathandizira pobowola kuti athyole bwino thanthwe ndikupanga dzenje la m'mimba mwake lomwe mukufuna.

Ubwino umodzi waukulu wa nyundo yotsika-bowo ndi makina obowola ndikutha kusunga mabowo molunjika komanso olondola, ngakhale pamiyala yolimba. Mphamvu yamphamvu yomwe imapangidwa ndi chopondera imatsimikizira kuti chobowolacho chimakhalabe cholowera, zomwe zimapangitsa kubowola kosalala komanso kolondola. Izi ndizofunikira makamaka pa ntchito monga migodi, kumanga ndi kukumba pansi pa nthaka, kumene ubwino wa borehole ndi wofunikira kwambiri kuti ntchitoyo ikhale yopambana.

Kuphatikiza apo, makina a DTH hammer ndi kubowola pang'ono amapereka kusinthasintha pakubowola. Itha kugwiritsidwa ntchito m'mapangidwe osiyanasiyana amiyala, kuphatikiza mapangidwe olimba ndi abrasive, pomwe njira zina zoboola zingavutike kuti zikwaniritse zomwe mukufuna. Kusinthasintha kumeneku kumapangitsa kuti nyundo zotsika-bowo zikhale zodziwika bwino pamapulojekiti osiyanasiyana obowola, kuyambira pokumba zitsime zamadzi mpaka kufufuza mafuta ndi gasi.

Mwachidule, nyundo zobowola pansi ndi zobowola ndizofunikira kwambiri pantchito yobowola, zomwe zimapereka mayankho amphamvu komanso ogwira mtima pobowola miyala yolimba. Kukhoza kwawo kupereka mphamvu zowononga kwambiri, kusunga kulondola kwa kubowola komanso kupereka kusinthasintha kumawapangitsa kukhala chida chofunikira kwambiri pakubowola kosiyanasiyana. Kumvetsetsa momwe nyundo za DTH ndi zobowola zimagwirira ntchito kumathandizira kumvetsetsa kufunikira kwake pakubowola komanso ntchito yawo kuthana ndi zovuta zoboola.
