液压凿岩机蓄能器是液压凿岩机系统中的一个重要部件。它可吸收系统工作过程中的压力脉冲,保护设备,同时它对活塞回程制动时的能量进行储存,在活塞冲程中加速到系统供油率不能满足时放出能量。试验表明,活塞回程能量如果能够充分利用起来,则凿岩机总能量利用率可提高10～20%,否则能量利用率将会小于50%,这就提出了研究蓄能器最大储能的条件,影响蓄能器储能的因素以及蓄能器怎 Hydraulic rock drill accumulator is an important part of the hydraulic rock drill system. It can absorb the pressure pulse during the working process of the system and protect the equipment. At the same time, it stores the energy during the piston back-stroke braking and releases the energy during the piston stroke when the system oil supply rate can not be satisfied. Tests show that if the piston backhaul energy can be fully utilized, the total energy utilization of rock drill can be increased by 10 ~ 20%, otherwise, the energy utilization rate will be less than 50%, which raises the conditions for studying the maximum energy storage of the accumulator, Accumulator energy storage factors and how the accumulator
