液压锤

工作原理

首先，液压动力系统提供动力，通过高压液压软管输送到桩锤，提升锤芯，当液压提升锤芯到一定高度时，通过液压换向阀，液压缸活塞上部与下部处于相同压力，此时活塞在重力的作用下自由下落，锤芯产生打击作用，完成打桩过程。

Working principle

First, the hydraulic power system provides power, through the high pressure hydraulic hose to the pile hammer, lifting the hammer core, when the hydraulic cylinder lift the hammer core to a certain height. through the hydraulic reversing valve, the upper  lower parts of the piston of the hydraulic cylinder are in the same pressure,  the piston is free to fall under the action of gravity,  the hammer core produces the blow effect To complete the pile driving process.
