液压反向流通的钻机的

WDH-500 hydraulic Reverse Circulation (RC) drilling rig is specially designed for air circulation down-the-hole (DTH) water well drilling, it is also good for DTH RC drilling in surface mining. It is ideal equipment for water well drilling and gold, copper etc mining exploration. The drilling rig WDH-500 is centrally driven by a Cummins diesel engine, with all the mechanism/systems of traveling, rotating, driving, feeding, rod loosing, lifting units and hydraulic legs, winches, mud pumps all hydraulically controlled/driven. This allows the drilling rig works with high efficiency, ease and conveniences. With the support of Medium or High Pressure Air Compressor, the WDH-500RC drilling rig can be used for DTH Air Circulation drilling, DTH Reverse Air Circulation drilling. If work with rotary drill bit, it can be used also for mud circulation drilling. This makes WDH-500 a most ideal equipment for water well, thermal water well and engineering foundation holes drilling. l Technical Specifications Model : WDH-500Max.
