Ukwahlulahlula kwequla lamanzi

Njengomatshini wokugrumba ojikelezayo, umatshini wokugrumba onempembelelo kunye nomatshini wokomba odibeneyo 3 iindidi.

I-Rotary drill

Ngentshukumo ethe nkqo ephindaphindanayo yesixhobo sokomba, isuntswana le-drill libetha ezantsi komngxuma ukuqhekeza ilitye.Ilula, kodwa ayinayo inkqubo yokugungxula okujikelezayo, ngoko ke ukusika akukwazi ukususwa ngexesha elifanayo ne-rig, okubangela ukusebenza okuphantsi.Ubunzulu bokomba buphakathi kweemitha ezingama-250, kwaye ezinye zinokufikelela kwi-500 ~ 600 yeemitha.Iindidi eziphambili zezi zilandelayo.I-drill ye-percussion elula esebenzisa ubunzima bomtya we-drill ukubetha ukwakheka.Kwisiphelo esisezantsi isixhobo sokomba ezimbalwa unako zhang ekhombe uphondo idiski, xa isixhobo sokomba phantsi intshukumo ubunzima baso ukuhla intshukumo, ivalve yokubamba evulekileyo, izoba idisc point kwisangqa yobubanzi malunga 1 m esikwe eliweni. , kwaye emva koko ugqithwe ngesixhobo sokunyusela intambo, bamba idiski ekuvaleni ubutyobo kwikhowuni echothiweyo kwaye ubeke phambili iqula livuleke kwakhona emva kokubamba ukukhutshwa kwediskhi yokusika.Ikhowuni yokubamba ithrust ikholisa ukugrunjwa ukuya kubunzulu obungama-40 ukuya kuma-50 m, elona linzulu li-100 ukuya kwi-150 m.

Intambo yocingo yempembelelo yempembelelo yentambo yenziwe ngemasti kunye nepuli yayo yokunyusa ephezulu, intambo yocingo, indlela yempembelelo, izixhobo zokomba (kuquka umbhobho wokubhoboza kunye nebit yokubhola), i-motor, njl. (Umfanekiso 4).Ngexesha lokusebenza, i-motor iqhuba indlela yempembelelo kwisixhobo sothumelo kwaye iqhube intambo yocingo ukwenza isixhobo sokugaya sibuyele phezulu nasezantsi.Xa usiya ezantsi, ubunzima be-drill benza ukuba isuntswana lisike kwaye liqhekeze ilitye, ngelixa ukunyuka kuxhomekeke ekutsaleni kwentambo yocingo.Ukuphakama kwesixhobo sokugaya esiwayo, okukuthi ubukhulu be-stroke, bunqunywe ngokwemiqathango yokwakheka kwamatye, ngokubanzi i-0.5 ~ 1 m, ilitye elinzima elinexabiso eliphezulu;I-frequency yempembelelo idla ngama-30 ~ 60 amaxesha / min.I-cuttings inqunyulwa emhlabeni nge-cylinder yokumpompa isanti, kwaye ingasetyenziselwa ukugaya isixhobo sokugaya esidibanisa i-drill bit kunye ne-santi pumping cylinder.Ukugaya kunye nokususa i-cuttings kuqhutyelwa ngexesha elifanayo, ukwenzela ukuba i-cuttings inqunywe ngokuthe ngqo kwi-cylinder yokupompa, kwaye emva kokuba ukuqokelela kugcwele, isixhobo sokubhoboza siphakanyiswe kwaye ukusika kuthululwa.Ukuze kuphuculwe ukuxhathisa kokunxiba kunye nesantya sokomba kancinci, umgubo wentsimbi ye-tungsten uhlala uvela ekupheleni kwesuntswana ukuze ube yi-alloy yokulungisa i-welding bit.I-compound drill.
