I-Kaishan KG420S Surface DTH Drilling Rig — Ukuguquguquka kombane okunamandla amabini kwiDizili yoMsebenzi onzima

I-Kaishan KG420S yirig yokugrumba ye-DTH ehlukeneyo enamandla ephuma kwi-DTH ebalaseleyo ngenkqubo yayo entsha yamandla amabini. Ngokudibanisa zombini injini yedizili evelisa amandla aphezulu kunye nemoto yombane esebenza kakuhle, le rig inika ukuguquguquka okungenakuthelekiswa nanto kokusebenza kunye nokonga iindleko. Yakhelwe ukugrumba okunobubanzi obukhulu kunye nokusetyenziswa kwemingxunya enzulu, i-KG420S sisisombululo esiphezulu kwiindawo zemigodi kunye nezokwakha apho amandla, ukuguquguquka, kunye nokusebenza okunzima kungaxoxiswana ngako.

Uphawu olucacileyo lwe-KG420S ziinkqubo zayo ezimbini zamandla ezizimeleyo: injini yedizili yeYuchai engama-58KW kunye nemoto yombane ye-55KW YE3. Ezi nkqubo zinokusebenza ngokwahlukeneyo, zivumela isixhobo ukuba sisebenze kwidizili xa sihamba okanye sikwiindawo ezikude, kwaye sitshintshele kumandla ombane xa kukho isiseko sendawo. Olu buchule bamandla amabini, olunikezelwa yiShaanxi Kaishan, lunciphisa kakhulu iindleko zokusebenza kunye namanqanaba engxolo ngelixa lubonelela ngoncedo oluthembekileyo ngexesha leeprojekthi zexesha elide.

Le rig yakhelwe phezu kwetshasi enzima enomkhondo wesakhelo esigoqekayo kunye nemoto yokuhamba nge-plunger, enika isiseko esiqinileyo sokubhola nge-torque ephezulu. Inkqubo yokuqhuba enamavili amane kunye nokukwazi ukunyuka ngamadigri angama-30 kuqinisekisa ukuba inokufikelela kwiindawo ezinzima kakhulu zebhentshi. Ukusingatha i-torque enkulu ye-5000N·m, i-rig ixhotyiswe ngenkqubo yemoto ejikelezayo kabini, eyenza ukuba ikwazi ukubhola imingxunya ukuya kuthi ga kwi-152mm ububanzi kwilitye eliqinileyo (f=6-20).

Iimechanikhi zokubhola zeKG420S zenzelwe ukuvelisa imveliso. Zinamandla amakhulu okuphakamisa e-40KN kunye nesilinda yeoyile kunye nenkqubo yokutya i-roller chain, eyenzelwe ukuphatha iihammer ze-DTH ze-4″ kunye neentonga zokubhola ezinkulu. Iisilinda ezandisiweyo zepitch kunye neengalo zokuphakamisa zivumela indawo echanekileyo yokubhonga, ngelixa i-970mm yokuhlawula iqinisekisa ukuba umzila wesikhokelo uhlala uzinzile kuyo yonke inkqubo yokubhola.

Ukuqina kwayo kubonakala kuzo zonke iinkalo ze-KG420S. Ukususela kwi-housing etyebileyo ukuya kwi-lifter cylinder kunye ne-chain eqinisiweyo, le matshini yakhelwe ukusinda kwiimeko ezinzima zokumba imigodi. Amandla ayo okumba imingxuma ethe tye ukuya kuthi ga kwi-2850mm kunye nemingxuma ethe nkqo ukuya kubunzulu beemitha ezingama-25 kuyenza ikwazi ukulungelelaniswa neemfuno ezahlukeneyo zeprojekthi, ukusuka ekumbeni imingxuma evulekileyo ukuya kumsebenzi wesiseko omkhulu.

Ukuze ivelise imveliso ephezulu, i-KG420S kufuneka idityaniswe nee-compressor ze-Kaishan ezine-high-pressure screw ezifana ne-KSCY570/12-550/15, i-LGCY17/18-18/15T, okanye i-KSCY650/20-700/17T. Olu dibaniso lubonelela ngomthamo womoya ophezulu (13-20 m³/min) ofunekayo ukunika amandla iihammer ze-4″ kunye nokususa ngokufanelekileyo imithamo emikhulu ye-cuttings, okwenza i-KG420S ibe lolona khetho lubalaseleyo lokubhola ngemveliso ephezulu.
