Abantu bezimboni kufanele bawakhethe kanjani amathuluzi okumba amatshe?
Ngokuthuthuka okusheshayo kokwakhiwa komnotho wembulunga yonke, isidingo samathuluzi okumba amatshe emikhakheni yobunjiniyela efana nezimayini, ukwakhiwa kwamandla, ukwakhiwa kwengqalasizinda kanye nokuthuthukiswa komgwaqo wezokuthutha kubonise ukuthambekela okukhuphukayo, futhi izidingo eziphakeme ziye zabekwa phambili zekhwalithi, ukuhlukahluka. kanye nokusebenza kwemikhiqizo yamathuluzi e-brazing.
Ngokwezinhlobo zemishini yokumba amatshe esetshenziswa kumaphrojekthi wokumba we-geotechnical, imikhiqizo esekelayo yamathuluzi okumba amatshe ingahlukaniswa ngezinhlobo eziyisithupha: Amathuluzi okumba isando aphezulu, i-Down the Hole Hammer Bits, amathuluzi okumba i-turbine yezimayini, amathuluzi okumba angemuva kanye ne- amathuluzi okumba okuhlola i-geological.
Amathuluzi aphezulu okumba isando
Amathuluzi aphezulu okumba isando atholakala phezulu kwemishini yokumba amatshe. Ithembele ku-piston ye-rock drill ukuthi ithinte ngokuqondile umsila wethuluzi lokubrazing. Amandla omthelela akhiqizwayo afinyelela ekhanda elikhanyayo ngomzimba ogqamile ngendlela yamaza okucindezeleka ukuze kuqedelwe ukuphuka kwedwala. Le ndlela yokumba amadwala isebenzisa igesi ecindezelwe noma uwoyela we-hydraulic njengomthombo wamandla, futhi amandla omthelela angaklanywa ngokuya ngezidingo zemishini, ngakho-ke inomthamo omkhulu.ukumba amatsheisilinganiso. Ukujula kwembobo yalolu hlobo lwethuluzi lokubhola ngokuvamile akudluli ku-35M, futhi ububanzi bokubhoboza abudluli ku-152M. Ithuluzi eliphezulu lokumba idwala elithinta isando lingahlukaniswa ngokwezigaba ezilandelayo:
(1) Amathuluzi okusika amatshe emishini elula yokutshiza amatshe. Isisindo salolu hlobo lomshini wokumba amadwala singaphansi kwama-35KG. Isebenzisa ukubamba ngesandla ngesandla noma ukwesekwa kwemilenze yomoya njengenkundla yokusebenza. Umthelela kanye nokuqhutshwa kokumba amatshe kuncane kakhulu. Imvamisa, imikhiqizo yamathuluzi okubhrawuza i-H19mm kanye ne-H22mm eyi-hexagonal integral brazing rods, kanye namakhanda okubraziza amise okwesicaba angu-38-42mm, amakhanda abrazing ahlukene kanye ne-Tapered button bit Rock Drill enamazinyo amane namazinyo amahlanu.
Imikhiqizo yethuluzi elikhulu kakhulu lokumba amatshe asetshenziswa emakethe yobunjiniyela bokumba amatshe yasekhaya izinduku zokubhrayela ezixhunywe ngekhoni ezingama-H22mm namakhanda e-solder ayisicaba amise okwe-flake. Phakathi kwazo, i-Φ38-Φ43mm eyindilinga enamazinyo amane namazinyo amahlanu ekhanda exhunywe nge-cone iyithuluzi elilula lokumba idwala elithuthukiswe eminyakeni yamuva nje ngepayipi lokubhoboza i-H22mm. Ngenxa yempilo yayo yesevisi ezinzile kanye nesivinini sokumba ngokushesha ezinhlotsheni zamatshe aqinile, iye yaqashelwa uphiko lokwakha.
(2) Amathuluzi okumba izimayini zokumba ngaphansi komhlaba. Imithombo yezimayini engaphansi komhlaba yenza ingxenye enkulu yemithombo yezimayini. Ngokuvamile, izimayini ezingaphansi komhlaba zingahlukaniswa zibe izinhlobo ezintathu: ukumba amatshe angashoni (6m), ukumba amatshe anembobo emaphakathi (ukujula kwembobo engu-10-30m) kanye nokumba imbobo ejulile (ukujula kwembobo engu-50-60m). Ezimbotsheni ezinembobo engaphansi kuka-43mm, izinti zokubethela ezixhumeke ngekhoni ezi-H22mm kanye nezinsimbi zokubethela eziyisicaba, ezimise okwesiphambano, noma eziyisiyingi zamazinyo zivame ukusetshenziswa. Emigodini enembobo enkulu kuno-43mm, kusetshenziswa ipayipi le-dirll engu-R32-H25-R32*1000m, ephelezelwa amakhanda okumba amatshe amise okwesiphambano noma ayindilinga.
