Umgaqo wokusebenza we-reverse circulation drilling rig

Reverse circulation drilling rigsisixhobo sokomba esijikelezayo. Ilungele ukwakhiwa kweendlela ezahlukeneyo eziyinkimbinkimbi ezifana ne-quicksand, i-silt, udongwe, ingqalutye, i-gravel layer, i-weathered rock, njl. imvula yobunjineli kunye nezinye iiprojekthi.

Umgaqo wokusebenza weumva ujikelezo lokomba rig:

Into ebizwa ngokuba yi-reverse circulation drilling rig ithetha ukuba xa isebenza, i-rotary disc iya kuqhuba i-drill bit ukusika kunye nokuqhekeza ilitye kunye nomhlaba emngxunyeni, ulwelo olugungxulwayo luya kuqukuqela kumngxuma ongezantsi ukusuka kwisithuba se-annular phakathi kombhobho wokubhobhoza. kunye nodonga lomngxuma, lupholise i-drill bit, luthwale ilitye kunye ne-slag yokomba umhlaba oye wanqunyulwa, kwaye ubuyele emhlabeni ukusuka kumbhobho we-drill. Kwangaxeshanye, ulwelo olugungxulwayo luya kubuyela emngxunyeni ukwenza umjikelo. Njengoko ububanzi bombhobho wangaphakathi wombhobho wokubhobhoza buncinane kakhulu kunombhobho, amanzi odaka kumbhobho wokubhobhoza aphakama ngokukhawuleza kunomjikelezo oqhelekileyo. Ayingomanzi acocekileyo kuphela, kodwa inokuzisa i-slag yokugrumba phezulu kombhobho wokugrumba kwaye iqukuqelele kwitanki yentlenga yodaka, apho udaka lunokuphinda lusetyenziswe emva kokucocwa.

Umgaqo kukubeka umbhobho wokubhola emngxunyeni ozaliswe lulwelo olugungxulwayo, kwaye ngokujikeleziswa kwetafile ejikelezayo, qhuba i-air tight square transmission rod kunye ne-drill bit ukujikeleza nokusika ilitye nomhlaba. Umoya ocinezelweyo utshizwa usuka kumbhobho osekupheleni kombhobho wokubhola, wenze umxube wodaka, isanti, amanzi kunye negesi ibe khaphukhaphu kunamanzi kumbhobho wokubhoboza ngokusikwa komhlaba nesanti. Ngenxa yefuthe elidityanisiweyo lomahluko woxinzelelo phakathi kwangaphakathi nangaphandle kombhobho wokuqhuba kunye nomfutho woxinzelelo lomoya, umxube werhasi yamanzi entlabathi yodaka uya kunyuka kunye nolwelo olugungxulwayo, kwaye uya kukhutshelwa echibini lodaka okanye kwindawo yokugcina amanzi. itanki ngombhobho woxinzelelo. Umhlaba, isanti, igrabile kunye nenkunkuma yamatye iya kuhlala kwidama lodaka, kwaye ulwelo olugungxulwayo luya kuqukuqela kumngxuma kwakhona.

Iimpawu zereverse circulation drilling rig:

1. I-reverse circulation drill ixhotyiswe ngengalo yomatshini kunye nombhobho wokubhobhoza, ongasetyenziselwa kumngxuma ochanekileyo kunye neemeko ezincinci ze-vertex angle. Kwangaxeshanye, i-drilling rig ixhotyiswe ne-winch encedisayo ye-hydraulic, enciphisa kakhulu ukuqina kwabasebenzi bomatshini, kwaye ilungele ukwakhiwa okukhuselekileyo kunye nempucuko yomatshini.

2. I-drilling rig ithatha i-crawler yobunjineli kunye ne-hydraulic walk chassis, ekulungele ukuhamba kwaye ifaneleke ngakumbi kumathafa, iinduli, iinduli kunye nezinye iifom zomhlaba. I-chassis ixhotyiswe nge-4 outriggers, ngoko ke i-drilling rig ine-vibration ephantsi kunye nokuzinza okulungileyo ngexesha lokwakhiwa kokugaya.

3. I-reverse circulation drilling rig iqhutywa ngamandla ombane, ngengxolo ephantsi kunye nongcoliseko, ukusebenza kakuhle okuphezulu kunye ne-coefficient enkulu yokugcina amandla.

4. I-reverse circulation drilling rig i-multifunctional, kwaye onke amacandelo aphambili ayimveliso eneendleko. Inkqubo ixhotyiswe ngokhuseleko loxinzelelo kunye nezixhobo ze-alamu.

5. Izibambo kunye nezixhobo zazo zonke ii-activators ze-reverse circulation drilling rig zifumaneka kwi-platform yokusebenza, efanelekileyo kwaye inokwethenjelwa ekusebenzeni nasekulawuleni.

6. I-reverse circulation drilling rig ithatha isakhelo esisodwa sokomba. Inkqubo yokugaya inkulu, ukuchasana kwe-torsion kukhulu, isakhiwo silula, ukugcinwa kulungeleka, ukufuduka kulungeleka, ukusebenza kwe-orifice kukulungele, kwaye i-angle enkulu ye-vertex drilling inokwakhiwa.

7. I-reverse circulation drilling rig ithatha intloko enkulu yamandla kunye nomsebenzi wokuchasana nempembelelo enkulu. Isantya sokujikeleza sifanelekile kwiimfuno zokujikeleza kwe-air reverse. Amandla okuphakamisa, i-torque kunye nezinye iiparameters zinokuhlangabezana neemfuno ze-100M yomoya ongekho nzulu ojikelezayo wokujikeleza kwe-DTH ukugaya kunye nezinye iimfuno zenkqubo.
