All-hydraulic power head drill, railway and highway bridge, ventilation shaft of coal mine, port terminals, and high-rise buildings and other large infrastructure construction drilling the ideal construction equipment, can be in diameter from 1.5 to 1.5 m, the rock uniaxial compressive strength of sigma c or less 200 mpa to choose aperture in the bedrock of the drilling, drilling depth of up to 130 m, the hole diameter in the layer of 6.0 m.
Full hydraulic drilling rig is driven by power head drill pipe, drill pipe drive drilling rotary drilling, USES the air reverse circulation mode of discharge, the power transfer for: electromotor→hydraulic pump→hydraulic motor→power head.
Machinery manufacturing industry developed mainly gathered in the coastal region of zhejiang province.Taizhou purros machinery co., LTD. Is located in the manufacturing industry developed new city of taizhou in zhejiang province.The purros production drilling power head, drilling power head, hydraulic power head, which can realize high ratio of performance and high precision automatic feed power head.
