The BF-150 reverse circulation drilling rig is an electric rotary drilling machine. It is an ideal hole-forming machine for pouring piles. It is suitable for silt, clay, gravel layer and weathered rock shale. It is more suitable for the foundation of many complicated layers such as gravel layer. Construction is therefore an ideal equipment for large-scale construction of bridges, buildings, water conservancy, electric power, telecommunications, engineering precipitation, etc.

Second, the rig structure and working principle

BF-150 reverse circulation drilling machine multi-function drilling rig is composed of electric motor, reducer, vacuum pump, hydraulic oil pump, main winch, auxiliary winch, oil cylinder, distribution box, drill stand, drill pipe, drill bit, reducer: rig reduce Deceleration for four-axis three-stage gears.
