Kaishan KG420B Surface DTH Drilling Rig — Ihamye kandi ifite imbaraga nyinshi

Kaishan KG420B ni imashini yo gucukura ya DTH ifite imikorere myiza, ikozwe mu bwoko bwa DTH, yagenewe imirimo iremereye yo gucukura amabuye y'agaciro no gucukura amabuye y'agaciro. Ifite inzira yihariye yo kuzingiramo hamwe na moteri ikomeye ya Yuchai ya silindiri 4, iyi mashini yubatswe kugira ngo itange umutekano udasanzwe ku misozi miremire no ku butaka butaringaniye. Ni amahitamo meza ku bakoresha bakeneye imashini yizewe kandi ifite amashanyarazi menshi ishobora gucukura imyobo minini mu bihe bigoye by’ubutaka.

Iyi moderi ni ivugurura rikomeye muri KG420, by’umwihariko yakozwe neza kugira ngo ihuze n’ibipimo by’ibyuka bihumanya ikirere mu gihe yongera imbaraga muri rusange za mekanike. Moteri ya Yuchai YC4DK80-T302 itanga imbaraga zikomeye za 58KW, ikaba ari yo shingiro ry’umuvuduko n’umuvuduko bya rotary rig. Shaanxi Kaishan yakoze iyi rig kugira ngo ifate uburebure bw’imyobo kuva kuri mm 90 kugeza kuri mm 130, ikaba imwe mu rig zifite ubushobozi bwo gukora ibintu byinshi mu rwego rwayo.

Ikintu cy’ingenzi mu mikorere ya KG420B ni uburyo bwo kuzunguruka bufatanye n’uburyo bwo kuzunguruka (± 10°). Ibi bituma icyuma gikomeza kugira imbaraga nke zo gukurura no gufata neza ndetse no mu gihe cyo kuzamuka imisozi ya dogere 30. Gukoresha moteri igendanwa ituma igenda neza, mu gihe sisitemu y’imodoka ifite amapine 4 itanga uburyo bwo gufata neza hasi mu byuma bikomeye. Inzu ifite imiterere ikomeye n’impeta zo guterura zifatanye byongera urwego rwo kuramba no gutwara ibintu mu buryo bw’inganda.

Umusaruro wo gucukura warushijeho kuba mwiza cyane binyuze mu gukoresha silinda nini yo guterura n'urunigi rw'amababi rukomejwe. Uku kuvugurura bivuze imbaraga zo guterura za 25KN n'uburyo bwo kugaburira bwa 3780mm, bitanga uburyo bwo gucunga neza inyundo no gucunga inkoni. Ifite torque ntarengwa ya 2000N·m kandi ikagira umuvuduko ugera kuri 140rpm, KG420B ishobora gukoresha neza amabuye akomeye (f=6-20) ikoresheje inyundo za 3″ cyangwa 4″.

Sisitemu y'icyuma gifata imirasire n'imirasire itanga ubushobozi bworoshye bwo gucukura. Hamwe n'aho imirasire yose ihengamiye kuri 185° n'uburebure bwa 145°, abakoresha bashobora kugera ku myanya igoye yo gucukura byoroshye. Uburyo bwo gucukura bwa 900mm butuma umuhanda uyobora ukomeza gukorana neza n'ubutaka, bigagabanya guhinda no kunoza uburyo imyobo ikora neza. Imyobo itambitse ishobora gucukurwa ku burebure buri hagati ya 350mm na 2750mm.

Kugira ngo dukore neza mu gucukura, turasaba guhuza KG420B na compressors za Kaishan zifite umuvuduko mwinshi nka KSCY550-13, KSCY570/12-550/15, cyangwa LGCY17/18-18/15T. Iyi rig ikwiriye cyane mu bucukuzi bw'amabuye y'agaciro buri hagati na bunini, kubaka imihanda, ndetse n'imishinga itandukanye y'ibikorwa remezo isaba gucukura byimbitse kandi neza.
