I-Kaishan KG420S Surface DTH Drilling Rig — Ukuguquguquka Kwedizili Enamandla Amabili Komsebenzi Onzima

I-Kaishan KG420S iyi-drill ye-DTH ehlukanisiwe enamandla evelele ngohlelo lwayo olusha lwamandla amabili. Ngokuhlanganisa injini yedizili ekhiqiza kakhulu kanye ne-motor kagesi esebenza kahle kakhulu, le rig inikeza ukuguquguquka kokusebenza okungenakuqhathaniswa kanye nokonga izindleko. Yakhelwe ukubhola okunobubanzi obukhulu kanye nezinhlelo zokusebenza zemigodi ejulile, i-KG420S iyisisombululo esiphezulu sezindawo zokumba kanye nezokwakha lapho amandla, ukuguquguquka, kanye nokusebenza okunzima kungaxoxiswana ngakho.

Isici esiyinhloko se-KG420S yizinhlelo zayo ezimbili zamandla ezizimele: injini yedizili ye-Yuchai engu-58KW kanye nenjini kagesi engu-55KW YE3. Lezi zinhlelo zingasetshenziswa ngokwehlukana, okuvumela i-rig ukuthi isebenze ngedizili lapho ihamba noma isezindaweni ezikude, futhi ishintshele kumandla kagesi lapho ingqalasizinda yasendaweni itholakala. Leli khono lamandla amabili, elinikezwa yiShaanxi Kaishan, linciphisa kakhulu izindleko zokusebenza kanye namazinga omsindo ngenkathi lihlinzeka ngokusekela okuthembekile phakathi kwamaphrojekthi esikhathi eside.

Le rig yakhelwe phezu kweshasi elinzima elinomzila wohlaka olugoqekayo kanye nenjini yokuhamba nge-plunger, enikeza isisekelo esiqinile sokubhoboza nge-torque ephezulu. Uhlelo lokushayela olunamasondo amane kanye nekhono lokukhuphuka ngamadigri angu-30 luqinisekisa ukuthi ingafinyelela ezindaweni ezinzima kakhulu zebhentshi. Ukuze iphathe i-torque enkulu engu-5000N·m, i-rig ifakwe uhlelo lwenjini olujikelezayo kabili, okwenza ikwazi ukubhoboza imigodi efinyelela ku-152mm ububanzi ngedwala eliqinile (f=6-20).

Izindlela zokubhoboza ze-KG420S zenzelwe ukukhiqiza. Inamandla amakhulu okuphakamisa angu-40KN kanye nesilinda samafutha kanye nohlelo lokuphakela uchungechunge lwe-roller, olwenzelwe ukuphatha izando ze-DTH ezingu-4″ kanye nezinduku zokubhoboza ezinobubanzi obukhulu. Amasilinda e-pitch anwetshiwe kanye nengalo yokuphakamisa avumela indawo eqondile yokubhoboza, kuyilapho isinxephezelo esingu-970mm siqinisekisa ukuthi isitimela esiqondisayo sihlala sizinzile kuyo yonke inqubo yokubhoboza.

Ukuqina kuyabonakala kuzo zonke izici ze-KG420S. Kusukela endlini eqinisiwe kuya kusilinda kanye neketanga lokuphakamisa eliqinisiwe, lo mshini wakhelwe ukusinda ezindaweni ezinzima kakhulu zokumba. Amandla awo okubhoboza imigodi evundlile efinyelela ku-2850mm kanye nemigodi evundlile kuya ekujuleni kwamamitha angu-25 kuwenza ukwazi ukuzivumelanisa nezimo nezidingo zephrojekthi ezahlukahlukene, kusukela ekumbeni imigodi evulekile kuya emsebenzini wesisekelo omkhulu.

Ukuze kukhiqizwe kahle kakhulu, i-KG420S kufanele ihlanganiswe nama-compressor ezikulufo ze-Kaishan ezinengcindezi ephezulu njenge-KSCY570/12-550/15, LGCY17/18-18/15T, noma i-KSCY650/20-700/17T. Le nhlanganisela inikeza umoya ophezulu (13-20 m³/min) odingekayo ukuze kunikwe amandla izando ezingu-4″ futhi kusulwe ngempumelelo amavolumu amakhulu ezinqunyiwe, okwenza i-KG420S ibe yisinqumo esihle kakhulu sokubhoboza okukhiqizwa kakhulu.
