Kaishan KG520 Surface DTH Drilling Rig — Imashini nini zikoresha moteri n'ubutaka burebure

Kaishan KG520 ni icyuma gicukura cya DTH gikomeye, gikoreshwa na mazutu gikozwe mu bwoko bwa DTH cyagenewe gucukura mu buryo bunini mu bucukuzi bw'amabuye y'agaciro no mu bucukuzi bw'amabuye y'agaciro bugoye cyane. Iki kimenyetso cy'iterambere rikomeye mu bushobozi, KG520 yakozwe kugira ngo ikore imyobo minini n'intebe zirambuye mu gihe ikomeza kuba ingirakamaro ku buryo Kaishan Group, uruganda rwa gatatu runini ku isi rukora compressor, ruzwiho ku rwego rw'isi. Shaanxi Kaishan itanga iyi mashini nk'irembo ryemewe ry'ubuhanga bwa Kaishan bushyigikiwe na Seattle.

Imwe mu ngaruka zikomeye muri KG520 ni uguhindura sisitemu yo kugaburira umuyoboro w’amashanyarazi ukoresha moteri. Bitandukanye n’imiyoboro isanzwe ya silindiri, imiterere y’umuyoboro w’amashanyarazi itanga imbaraga zo guterura no kugaburira mu gihe cyose cy’imiyoboro ya 4150mm. Iyi miterere yongera cyane ubwizerwe bw’umuyoboro mu gihe cyo gucukura imyobo miremire (Φ105-152mm) kandi ikagabanya ibisabwa mu kubungabunga bikunze kujyana na silindiri za hydraulic zigenda zikora cyane.

Kuba ubutaka bushobora kwihuta ni ikindi kimenyetso cya KG520. Ifite aho ihagarara ha metero 440—hafi inshuro ebyiri z’aho ihagaze—iyi mashini ishobora kunyura hejuru y’ibisigazwa n’imbogamizi bikomeye idakomeretse ku gice cyo munsi y’imodoka. Sisitemu yo kuzunguruka, ikoresha moteri zifite imbaraga nyinshi, ituma imashini ya 6500KG ishobora kugenda kugeza kuri kilometero 4 ku isaha no gutsinda ubushyuhe bwa 30°, bigatuma iba imwe mu mashini zigendanwa cyane mu rwego rwayo rw’uburemere.

Ingufu zo gucukura za KG520 zishingiye kuri moteri ya Yuchai YC4DK100-T304 ifite ubushobozi bwo gukora cyane itanga 73.5KW. Izi ngufu zitwara sisitemu izunguruka ifite ubushobozi bwo gukurura 4000N·m kandi ikagenda yihuta kugeza kuri 100rpm. Iyo ihujwe n'imbaraga zo gucukura za 4150mm, zitwara inkoni ndende zo gucukura (3m), KG520 igabanya igihe cyo gucukura gihinduka kandi ikongera igihe cyo "gucukura bit-on-bottom" kugira ngo ikoreshwe neza buri munsi.

Kugira ngo inyubako irambe, twakonjesheje inzu kandi dushimangira ibyuma biteranya imirasire n'imirasire. Iyi nyubako ifite kandi uburyo bwo gukusanya ivumbi ryagutse hamwe na sisitemu ikomeye yo kuringaniza inzira ya ± 10° kugira ngo habeho uburyo bwo guhuza neza imyobo ku ntebe zitangana. Uburebure ntarengwa bwo kugera ku burebure bwa 3500mm, butanga ibahasha nini yo gucukura ku bikorwa byihariye nko gucukura isura no gukomeza imisozi.

Shaanxi Kaishan asaba guhuza KG520 na compressors zitwara screw zifite umuvuduko mwinshi nka KSCY310/22 cyangwa LGCY19/21. Izi units zitanga ingano y'umwuka ya 15-22m³/min ikenewe kugira ngo zisukure neza imyobo minini ya Φ105-152mm kandi zitware inyundo za DTH zifite ingano ya 4″ cyangwa 5″. Kuva yashingwa mu 1956, Kaishan yanogeje izi mashini zikoresha rig-compressor kugira ngo zitange ibiciro biri hasi kuri metero imwe mu nganda.
