Atlas. The structure and performance characteristics of Copco's hydraulic rock drills are:

(1) are the use of double-sided oil distribution principle;

(2) The piston is slender, the impact stress wave amplitude is small, the duration is long, and the piston and the drilling tool have long service life;

(3) with a drill rod rebound elastic buffer and absorption device, improve the life of the rock drill and drill;

(4) with 2 or 3 gear stroke regulator;

(5) Some models are equipped with a drill puller to facilitate the handling of the card drill;

(6) the impact pressure and rotary pressure are relatively high, the impact pressure is generally 20-25MPa, most of the 23MPa, rotary pressure is generally 20-25MPa, most of the 20MPa;

(7) The impact frequency is relatively high, up to 102Hz, mostly 60Hz.
