Shanxi rock drill rock drill rock drill 2013 new models offer full hot Jinan 18615651196 rock drill rock drill is used to direct exploitation of stone tools. It is on the rock drilling a borehole in order to go into the dynamite exploded rocks, thus completing the extraction of stone or other rock engineering. In addition, the drilling machine can also be converted to destroy, used broken concrete like the hard layer. Working principle is based on the impact of broken rock drill principle works. Work to do high piston reciprocating motion, continue to impact on the solder tail. Under the force of the impact, was the tip of the drill head wedge and chisel into the rock crushing a certain depth, the formation of a dent. Pistons returned after Qianzai turned a certain angle, the piston moves forward again when the solder tail shock, and the formation of a new dent. Dent sector between two blocks is generated by the horizontal component of solder head was cut. Pistons continue to impact solder tail, and from the center hole Qianzai continuous input of compressed air or pressurized water that will rock slag discharge hole, but that the formation of a certain depth of the circular hole features a) hydraulic rock drill checked before starting the accumulator The inflation pressure is normal; 2) Drilling should be placed in the propeller drilling location, 3) If you can not smoothly hole drilling machines, 4) when the replacement drill bits, 5) overhaul of hydraulic components only in extreme cleaning under the conditions, 6) should be regularly checked the oil level in the lubricator and oil supply; performance parameters surge power: 5.5kw impact frequency: 50Hz Rotation speed: 350 (r / min) Max torque: 175N.m shock pressure: 17Mpa Contact: Maguo Jing Contact: 18615651196 landline number :0531-86109500 QQ: 1879692311
