Ukuhlelwa kwebit yamalahle kunye nokusetyenziswa kwayo yintoni

Ukuqhuba amalahle ngoku kuqhele ukusetyenziswa kushishino lokomba izinto ezintathu, amandla ahlulwe abe ngamacandelo amabini, UHLOBO I lokomba amatye athambileyo, uhlobo lwe-II lwelitye eliqinileyo kunye nokugrumba ilitye eliqinileyo.Ngesantya esikhawulezayo sokomba, ukugubungela okubanzi, ukonga ixesha, ukonga umzamo, ujongano olulula, oluhlala ixesha elide kunye nezinye iimpawu ezibalaseleyo.Intwana yamalahle isetyenziswa ekwembeni amalahle athambileyo, indlela yamalahle aqinileyo kunye namatye amalahle.Ngezantsi yiZhengzhou ishishini lamahlathi i-xiaobian ukwazisa ulwahlulo kunye nokusetyenziswa kwedrill yamalahle.

1. Iinkcukacha kunye neemodeli zamalahle okugaya amalahle
Imilinganiselo yebit yamalahle kunye neemodeli zohlulwe zibe ф 28mm, ф 30mm, ф 32mm, ф 38mm, ф 42mm ngokobubanzi bamaphiko amabini.

2. Ukuhlelwa kweebhithi zokugaya amalahle
Ngokwendlela yokusebenza ayifani, i-drill yamalahle inokwahlulwa ibe luvavanyo olomileyo kunye novavanyo olumanzi ezimbini.Intwana yovavanyo olomileyo yintwana engaboneleli ngamanzi anothuli kwaye ayinamjelo wokhuseleko wonikezelo lwamandla kuyo yonke inkqubo yokomba.Intwana yovavanyo olumanzi: isuntswana elinamanzi anothuli anikezelweyo ngexesha lonke lenkqubo yokomba kunye nendlela ekhuselekileyo yonikezelo lombane.Ngokwezinto ezimbini zamaphiko azifani, i-bit yamalahle yahlulwe kwi-carbide cutter bit kunye ne-diamond composite sheet (PDC) bit.

I-3, ukusetyenziswa okuphambili kwe-drill yamalahle
Ifakwe kwi-drilling yekhemikhali yamalahle, isitshixo sokuthambile - i-rock reinforcement i-anchor bolt yokuxhasa umngxuma wokuxhasa.Ngokuqhelekileyo isetyenziswa kwindlela yamalahle enamandla amatye F ≤8, ngakumbi kumsebenzi wenkxaso yebholithi yendlela yamalahle, inokugrumba umngxuma wentambo yeankile ye-slab-in-place slab.

E-China, intsimi yamalahle inezi mpawu zilandelayo: okokuqala, umthamo wemarike, ngenxa yokuba i-bit yamalahle isetyenziswe kwishishini lokugaya amalahle, indawo ephakathi kunye nesezantsi yemfuno inkulu kakhulu;Okwesibini, inani lilonke lamashishini okuvelisa likhulu, kwaye isikali sokusebenza sincinci, sisasazeke kakhulu, kwaye ugxininiso loshishino luphantsi.

Ngentla "yintoni ulwahlulo lwentwana yamalahle kunye nokusetyenziswa kwayo?"Ndiyathemba ukuba ndingakunceda.Ukuba ufuna ukuqonda umxholo wezinye izixhobo zemigodi, unokunikela ingqalelo kule webhusayithi, kodwa udibanise nenkonzo yethu yabathengi be-intanethi, senza konke okusemandleni ethu ukukukhonza.
