The fully hydraulic tunnel drilling rig for coal mines has excellent performance and long service life. It is the leader in the industry. It is the R&D and production base for fully hydraulic tunnel drilling rigs in my country. The tunnel drilling rig for coal mines is mainly used for drilling gas drainage holes underground in coal mines, grouting fire extinguishing holes, and coal seam water injection holes to prevent sudden unloading. Pressure drilling, geological exploration holes and other engineering holes. Suitable for various coal seam rock formations with rock solidity coefficients. It is required that the cross-section of the tunnel or drilling field is larger than square meters, and the height is larger than the width. The hydraulic system is a double oil pump system. The rotation speed and feed pressure of the drill?
By adjusting the displacement of the variable motor to adjust the rotation speed, a constant rotation speed can be achieved. Power speed regulation. That is, the lower the speed, the greater the torque, and the output power remains unchanged
By adjusting the displacement of the variable pump to adjust the rotation speed, constant torque speed regulation can be achieved. That is, the rotational speed changes but the torque remains unchanged.
The reverse rotation torque of the gyrator exceeds the forward rotation torque, ensuring that the drill pipe thread can still be smoothly unscrewed after drilling with a large torque. The drilling rig is easy to operate. The operation panel has clear and intuitive markings and you can operate it after reading the instructions. No special training is required.
