Performance Characteristics of Hydraulic System of Conventional Hydraulic drill

Hydraulic system of hydraulic rock drill performance characteristics and working principle of the hydraulic rock drill is in recent years the emergence of a new type of rock drill, basic can be divided into two types: one is a small hand-held, its impact energy is small, mainly is used instead of the traditional pneumatic pick, most and small mining - loader, hydraulic truck, etc;The other is the large airborne type, which is mostly based on the backhoe working device of the hydraulic excavator. The backhoe bucket is changed into the drill to carry out the work, which is operated by the driver of the excavator in the driving room.This kind of drill has large energy, which is generally within the range of 1~6kN·m.

Hydraulic drill is driven by high pressure oil to push piston percussion solder, with an independent rotary mechanism of a drilling machine.The reciprocating motion of the piston is controlled by a valve (or without a valve).As the oil pressure is much higher than the gas pressure, up to 10 mpa.Although similar to the pneumatic drill, the piston has smaller diameter, larger length and better waveform.When the piston motion changes direction and produces peak pressure, an energy accumulator is installed.Features: fast drilling rate (more than twice higher than the wind drill), high impact power, high torque, high frequency;Adjustable and low energy consumption (about 1/3 of the air drill);High efficiency;Automation and computer control make the working environment greatly improved.

Hydraulic drilling machine is mainly used for digging medium and deep gun holes in mine pit, which is suitable for different height of roadway. It can be used for soft and hard various kinds of rocks and different sizes of drilling holes.It is applicable to both the rock roadway and the mining roadway.
