原01-30型凿岩机是活阀式的一种机型,耗风量大,凿岩效率低,已被列为国家淘汰产品。为了使老设备恢复青春,我厂对01-30型凿岩机进行了改造。修改量并不大,只要更换一套配气机构就行。改造后的01-30凿岩机与原机相比:扭转力矩提高39%,冲击频率提高37.5%,冲击功提高11%,纯凿岩速度由200(毫米/分)提高到377.4(毫米/分),耗风量下降了17.6%。在4～5个大气压下,
The original 01-30 type rock drill is a valve type, the consumption of large amount of wind, rock drilling efficiency is low, has been classified as the national phase-out products. In order to rejuvenate the old equipment, I plant on 01-30 rock drill was transformed. Modification is not large, as long as the replacement of a gas distribution agencies on the line. Compared with the original machine, the modified 01-30 rock drill increased the torsion moment by 39%, the impact frequency by 37.5%, the impact energy by 11% and the pure rock drilling speed increased from 200 (mm / min) to 377.4 (mm / min) , The consumption of air decreased by 17.6%. At 4 to 5 atmospheres,
