How does a hydraulic rock drill work?

The hydraulic rock drill is a rock drilling machine that uses high-pressure oil as a power to push the piston to impact the drill and attaches an independent rotary mechanism. The piston is controlled by the valve (and also has no valve) to reciprocate. Since the oil pressure is much higher than the gas pressure, it is more than 10MPa.

How much energy does a hydraulic rock drill use?

The energy of such rock drills are relatively large, generally in the range of 1~6kN·m. YYT28 hydraulic rock drill is a full-leg hydraulic rock drill. It can be used with various hydraulic stations. It has high drilling speed, low power consumption, light noise, and fewer faults.

Does Marini offer a hydraulic rock drill attachment?

Marini designs and produces certified hydraulic rock drill attachments ready to be installed on mini, midi and big self-propelled machines. The MR-1 can be equipped with a pneumatic or hydraulic rotation motor (for use in DTH drilling), or with a top hammer rock drill for smaller holes.

How to store a hydraulic rock drill?

For long-term storage, apply a tight protective plug to plug all the ports, thoroughly clean the machine, and drain the gas from the accumulator. The rock drill should be stored in a dry and clean place. Most hydraulic rock drills are equipped with cushioning devices, and some heavy-duty hydraulic rock drills also have a recoil device.

What are the advantages and disadvantages of a rock drill?

Its advantages: fast drilling speed (more than twice higher than a pneumatic rock drill), high impact power, high torque, high frequency; adjustable, low energy consumption (about 1/3 of aerodynamic rock drill); high efficiency; easy to automate, and computer control, less stuck drills, long tool life, and greatly improved working environment.

How to open a hole in a rock drill?

If the rock drill cannot open the hole smoothly, the rock drill should be operated first to retreat, and then the rock drill should be moved forward to re-open the hole. When replacing the bit, the bit should be lightly pressed against the rock to reverse the motor of the hydraulic rock drill to realize the motorized unloading head.
