作者对影响凿岩生产能力的两个因素,即压缩空气的工作压力和轴向力数值作了研究。特别影响凿岩速度的因素有两个:轴向力及压缩空气的工作压力。凿岩机所发出的功率可由下式表示:E=е×n, (1)式中:e——一次冲击能量;n——每分钟活塞冲击数;E——每分钟凿岩机所发出的总功率。并考虑:e=paS (2)及n=((p·a)/(wS))~(1/2)(3)式中:p——作用于活塞的压缩空气的工作压力;a——活塞运动的气缸面积;

The author has studied two factors that affect the productivity of rock drilling, namely the working pressure and the axial force of compressed air. There are two factors that affect drilling speed in particular: axial force and working pressure of compressed air. The power produced by the rock drill can be expressed as: E = е × n, (1) where: e - the impact energy once; n - the number of piston impacts per minute; E - the total power delivered by the rock drill per minute. And consider: e = paS (2) and n = ((p · a) / (wS)) ~ (1/2) (3) where: p - working pressure of the compressed air acting on the piston; a- - Piston movement of the cylinder area;
