DY 型风镐采用的是单程供气原理,它是把活塞回程能量转化为冲程能量的一种独特结构。它只在活塞回程时供给压气,使活塞在气缸里形成连续往复运动的循环过程。应用工程热力学绝热过程定律,回程时使前室压气充分膨胀,把压气势能转化为活塞动能,后室则进行绝热压缩,把活塞回程 DY-type picks using one-way gas supply principle, which is the piston back stroke energy into a unique structure of stroke energy. It only supplies pressure during the return stroke of the piston so that the piston forms a continuous cycle of reciprocation in the cylinder. Applied Engineering Thermodynamics The law of adiabatic process, the back chamber when the anterior chamber fully compressed gas, the pressure potential energy into piston kinetic energy, after the room is adiabatic compression, the piston back
