DTH hammers are specialized tools designed for breaking and drilling in underground engineering. Comprising key components such as pistons, drill bits, air pipes, and air circuits, these hammers operate on the principle of using high-pressure air or hydraulically driven pistons to continuously impact the ground or borehole walls. Let's delve deeper into the fascinating world of DTH hammers.

To initiate the process, DTH hammers are installed on a drilling rig using drill pipes or other connecting methods. Compressed air or hydraulic pressure is then directed through the pipeline to the piston within the DTH hammer, creating high-pressure airflow or pressure. As the piston exerts force, the drill bit reciprocates and delivers radial impacts to the ground or drilling wall.

During this movement, the drill bit's impact force is capable of cracking, breaking, and excavating underground rock or concrete materials. Simultaneously, as the piston moves up and down, the drill bit undergoes continuous rotation. This combination of intense impact and rotation enables the forward excavation of underground materials.

It's crucial to ensure that the size and shape of DTH hammers align with the hardness and strength of the underground materials to prevent equipment damage and operational difficulties. Additionally, precise control of the air or hydraulic pressure within the DTH hammer is essential to maintain safe and effective operations.

In summary, the working principle of DTH hammers involves driving the piston through high-pressure air or hydraulic pressure, causing the drill bit to reciprocate and accomplish the task of underground excavation or crushing. A firm grasp of this principle and proper usage methods can significantly enhance the efficiency and quality of underground engineering work.
