Understanding DTH Hammers: How They Power Deep Rock Drilling Efficiency
Introduction 介绍
In modern mining, quarrying, and water well drilling, efficiency and reliability are the keys to success. One of the most important tools behind these achievements is the Down-The-Hole (DTH) hammer. At Fasikon Drilling Tools, we specialize in producing high-performance DTH hammers and bits designed to deliver powerful impact energy and long service life, even under the toughest geological conditions.
在现代采矿、采石和水井钻探中，效率和可靠性是成功的关键。这些成就背后最重要的工具之一是潜孔锤。在芳尚康钻探工具公司，我们专注于生产高性能的潜孔锤和钻头，旨在提供强大的冲击能量和长久的使用寿命，即使在最恶劣的地质条件下也不例外。
What is a DTH Hammer?什么是潜孔锤？
A DTH hammer is a pneumatic drilling tool located directly behind the drill bit. Unlike top hammer systems, where the impact occurs at the surface and energy travels through the drill rods, a DTH hammer operates at the bottom of the hole, minimizing energy loss and increasing penetration speed.
潜孔锤是一种位于钻头正后方的气动钻孔工具。与冲击力发生在地表且能量通过钻杆传递的顶部锤击系统不同，潜孔锤在孔底工作，能最大限度地减少能量损失并提高钻进速度。
The hammer converts compressed air into continuous percussive impacts that drive the bit into the rock. This system ensures straight boreholes, faster drilling, and reduced wear on the drill string.
锤子将压缩空气转化为连续的冲击力，从而将钻头打入岩石。这种系统能确保钻孔笔直、钻进速度更快，并减少钻柱的磨损。
How Does a DTH Hammer Work?潜孔锤是如何工作的？
The basic principle involves a piston that moves back and forth within the hammer chamber, powered by compressed air. Each stroke of the piston delivers a direct impact to the bit shank, crushing rock at the hole’s face. The same airflow also removes rock cuttings through the bit’s exhaust ports, keeping the hole clean for efficient drilling.
其基本原理是：在锤击腔内有一个活塞，由压缩空气驱动来回移动。活塞的每次往复运动都会直接冲击钻头杆，从而在孔底破碎岩石。同样的气流还会通过钻头的排气口清除岩屑，保持孔洞清洁，以实现高效钻进。
