Kune marudzi maviri: imwe iri murotary rotary drilling rig pahwaro hwekuwedzera kwesimba rekugadzirisa, kunyanya pakuchera rotary, kana uchinge wasangana nematombo ematombo ane simba rekuchera maviri-chinangwa tsime rekuchera, kuchinjika kwakasimba kune akasiyana strata;Imwe yacho ndeyekukanganisa uye kutenderera chiitiko chakasanganiswa netsime rekuchera rig, senge pneumatic DTH sando drill.DTH hammer drill (FIG. 5) inoumbwa necylinder liner uye piston inofamba ichikwira nekudzika muhumburumbira liner.Mugumo wepazasi wecylinder liner wakabatana ne drill bit, uye wekumusoro wakabatana ne drill pombi kuburikidza ne threaded joint.Mhepo yepamusoro-soro inopiwa nemhepo compressor ndeye 0.7 ~ 1.4 mpa kuburikidza nevhavhavha yecheki iri pamusoro pepiston, muparadzi wemhepo uye mhepo inopinza pazasi pepiston, uye mafambiro episton anosundirwa kumusoro nekudzika se700 ~ 1200. nguva/min, kuitira kuti piston inowanzokanganisa chibooreso.Kuwedzera kugona kwechibhorani chekuboora dombo.Panguva imwecheteyo, pombi yekubooresa inotenderera ichimhanya yakaderera ye35 ~ 60 RPM.Mhepo kubva kumusoro nepamusoro maburi episton inoyerera ichidzika mubhiti kuti itonhodze kadiki yacho uye kuunza zvidimbu zvepazasi kubva mutsime.Mamisikirwo echikamu chekugezesa uye chinotenderera zvakanaka chakangofanana neicho che rotary drill ine mweya wakadzvanywa, uye bhiti rinoshandiswa ndeye tungsten carbide ball zino bhiti kana roller cone bit.Pneumatic DTH hammer drill inogona kushandiswa kuchera matsime akadzika mumatombo akaomarara.Kumhanya kwekuchera kwakakwirira, uye kukurumidza kwekuchera hakusi kuderera nekuda kwekuwedzera kwekuchera kudzika, uye gomba rekuchera rakananga.
Kuti uenderane nezvinodiwa zvakasiyana strata drilling, kunatsiridza kuchera, tsime rekuchera rig ine-multi-purpose drilling rig uye yakazara hydraulic transmission uye kutonga kwegwaro rebudiriro: ndiko kuti, rigi yekuchera ine zvakasiyana siyana zvekushandisa uye zvishongedzo. , inogona kushandisa kukanganisa, rotary uye DTH sando uye dzimwe nzira dzekuchera;Kugeza madhaka, mhepo yakamanikidzwa kugeza zvakanaka uye kutenderera kutenderera zvakanaka kugeza zvakanaka kunogona kushandiswa zvakare.
