INNOVATIVE OIL-DYNAMIC PERCUSSION MACHINE WORKING AT CONSTANT HYDRAULIC PRESSURE

摘要

Oily dynamic impact drilling machine, with main body (1), wherein having piston (3), it has converted hydraulic power supply circuit in machine power, those tools (5) transmit machine power and generate dismounting, and nitrogen charging high pressure hydraulic accumulator (2) has the supply circuit of the hydraulic power supply of storage function and keeps operating pressure steady state value each other by modulator slide valve (4); The mechanism kinematic, the displacement of piston and his active are into oil extraction control port (19,11).
