气动凿岩机使用高达1.8～2.0MPa的压气有助于提高凿岩速度。有效地利用压气能量可以大大提高气动凿岩机的作业能力。这是通过优化气动凿岩机的设计参数和配气系统来实现的。工作腔的充气体积和决定气流延续时间的设计参数是气动凿岩机工作性能的关键性参数。工作腔充气体积的定义是:打开或关闭进气通道时该腔室的体积。无阀气动凿岩机是通过活塞的移动来配气的,当活塞处于其运动行程(进气行程)的某一段时,气流便进入工作腔内。进气行
Pneumatic rock drills with up to 1.8 ~ 2.0MPa pressure help to improve the drilling speed. The effective use of gas pressure can greatly improve the working ability of pneumatic rock drill. This is achieved by optimizing the design parameters of the pneumatic rock drill and the gas distribution system. The working chamber’s inflatable volume and the design parameters that determine the air flow duration are key parameters of the performance of a pneumatic rock drill. The working chamber inflation volume is defined as the volume of the chamber when the intake passage is opened or closed. Valveless pneumatic rock drilling machine is through the movement of the piston to gas, when the piston is in its movement stroke (intake stroke) of a certain period, the air flow into the working chamber.
