imashini izunguruka

Hariho ubwoko bubiri: bumwe buri mukuzunguruka kuzenguruka kuzenguruka hashingiwe ku kongeramo uburyo bwingaruka, cyane cyane kubucukuzi bwizunguruka, mugihe uhuye nigitaka cyamabuye hamwe ningaruka zo gucukura ibintu bibiri-bigamije gucukura neza, guhuza n'imiterere itandukanye;Ibindi ningaruka nigikorwa cyo kuzunguruka byahujwe nicyuma cyo gucukura amariba, nka pneumatic DTH inyundo.Imyitozo ya DTH ya nyundo (FIG. 5) igizwe na silinderi hamwe na piston izamuka ikamanuka mumurongo wa silinderi.Impera yo hepfo ya silinderi ihujwe na biti ya drill, naho impera yo hejuru ihujwe numuyoboro wimyitozo unyuze mumutwe.Umuyaga mwinshi utangwa na compressor de air ni 0.7 ~ 1.4 mpa unyuze kuri valve igenzura hejuru ya piston, ikwirakwiza ikirere hamwe n’umwuka uri munsi ya piston, hamwe ninshuro ziterwa na piston irasunikwa hejuru no hasi nka 700 ~ 1200 inshuro / min, kugirango piston ikunze kugira ingaruka kuri bito bito.Kongera ubushobozi bwimyitozo bito yo gucukura urutare.Muri icyo gihe, umuyoboro wimyitozo uzunguruka ku muvuduko wo hasi wa 35 ~ 60 RPM.Umwuka uva mu mwobo wo hejuru no hepfo ya piston umanuka muri bito kugirango ukonje bito hanyuma uzane ibice byo hasi-umwobo uva mu iriba.Imiterere yikizunguruka no kuzenguruka neza igice cyo gukaraba ni kimwe cyane cyane nicy'umuzenguruko uzunguruka hamwe n'umwuka uhumanye, kandi bito bikoreshwa ni tungsten karbide ball ball amenyo bit cyangwa roller cone bit.Pneumatic DTH inyundo irashobora gukoreshwa mugucukura Iriba ryimbitse mubice bikomeye.Umuvuduko wo gucukura ni mwinshi, kandi umuvuduko wo gucukura ntugabanuka kubera ubwiyongere bwimbitse, kandi umwobo wo gucukura uragororotse.

Kugirango uhuze n'ibikenerwa mu gucukura ibice bitandukanye, kunoza imikorere yo gucukura, urugomero rwo gucukura neza ni ruganda rwinshi rwo gucukura no gukwirakwiza hydraulic yuzuye no kugenzura icyerekezo cyiterambere: ni ukuvuga uruganda rucukura rufite ibikoresho nibikoresho bitandukanye. , irashobora gukoresha ingaruka, kuzunguruka na DTH inyundo nubundi buryo bwo gucukura;Gukaraba neza ibyondo, guhumeka umwuka neza no gukaraba neza no guhinduranya neza gukaraba neza nabyo birashobora gukoreshwa.
