Martillos en fondo sin válvulas ni tubos

Martillos en fondo DTH sin válvulas ni tubos en la parte inferior de una barra de perforación. El martillo se acciona mediante aire comprimido transmitido a través de la barra de perforación para accionar el pistón y producir fuerza de impacto, que se introduce en las rocas para perforarlas y triturarlas. La perforación DTH puede aplicarse en minería, canteras, perforación de pozos de agua, pilotaje de cimientos, etc. El martillo DTH utiliza aire comprimido para producir potencia de impacto, impulsando así las brocas para triturar las rocas.

Features of Valveless/Tubeless Down the hole DTH Hammers

The Valveless/Tubeless Down-the-Hole (DTH) Hammers represent an advanced evolution in Down-the-Hole drilling technology, engineered to maximize drilling efficiency and tool longevity. By incorporating optimized internal designs and leveraging superior manufacturing processes, these hammers deliver consistent and powerful percussive action with reduced operational costs. This makes them a highly reliable choice for demanding drilling applications where both performance and durability are paramount.

Here are the key features of the AME Valveless/Tubeless DTH Hammer:

  • Extraordinary penetration rate: Designed for maximum impact frequency and efficient energy transfer to the bit, leading to faster drilling through challenging rock formations.
  • Less air, more production: Optimized air consumption allows for greater efficiency from your compressor, reducing fuel costs and maximizing the amount of drilling achieved per unit of air.
  • Less downtime, longer duration: Built with robust, wear-resistant components and precision manufacturing, these hammers are designed for extended operational life, significantly reducing maintenance needs and costly interruptions.
  • Premium material, fine CNC and heat-treatment manufacturing processes, and optimized design: Constructed from high-grade alloys and subjected to advanced CNC machining and specialized heat treatments, ensuring exceptional strength, durability, and a perfectly balanced internal mechanism.
  • Good stability and reliability: The hammer’s design promotes stable operation within the borehole, contributing to straighter holes and consistent performance, minimizing issues during drilling.
  • High impact frequency: Delivers rapid, powerful blows to the drill bit, which is crucial for breaking hard and abrasive rock efficiently.
  • Lowered compressed air consumption: An optimized internal air distribution system ensures that the hammer operates effectively with less air volume, contributing to energy savings.
  • Long lifespan: The combination of premium materials, precise manufacturing, and optimized design results in a hammer that can withstand prolonged use in harsh conditions, offering an excellent return on investment.

Applications of  Down the hole DTH Hammers

Down the hole DTH Hammers is a highly versatile and robust drilling tool, designed to excel in a wide range of demanding applications where efficient and precise penetration through hard and abrasive rock is required. Its optimized design for high impact frequency and reduced air consumption makes it an ideal choice for projects prioritizing both speed and cost-effectiveness across various industries.

Here are the primary applications of the AME Valveless / Tubeless DTH Hammer:

  • Minería: Essential for drilling blast holes, exploration holes, and pre-splitting holes in both open-pit and underground mines, contributing to efficient ore extraction.
  • Quarrying: Used extensively in quarries for the fragmentation of rock, aggregate production, and the extraction of dimensional stone, ensuring high productivity.
  • Perforación de pozos de agua: A preferred tool for creating boreholes to access groundwater for agricultural irrigation, industrial use, and domestic water supply.
  • Geothermal Well Drilling: Critical for drilling the deep and often challenging boreholes required for geothermal energy systems, penetrating diverse rock formations.
  • Foundation Piling: Employed in construction projects to drill precise and stable holes for foundation piles, micro-piles, and other ground support applications.
  • General Construction and Infrastructure: Applicable in various civil engineering works such as road building, tunneling, dam construction, and other rock excavation tasks.

Structure of AME Valveless/Tubeless DTH Hammer

Valveless/Tubeless Down-the-hole (DTH) hammers, like other down-the-hole hammers, are a complex mechanical device designed to deliver powerful impacts directly to the drill bit at the bottom of a borehole. While specific internal designs can vary slightly between manufacturers and models for optimization, the fundamental structure comprises several key components working in unison. Compressed air enters the hammer, actuating a piston that reciprocates at high frequency, striking the bit. This percussive action, combined with rotation from the drill rig, efficiently breaks rock.

Here are the main components and their roles in the structure of a Valveless / Tubeless DTH hammer:

  • Top Sub (Backhead): This is the uppermost part of the hammer, which connects to the drill pipe. It funnels compressed air into the hammer and transfers rotational torque from the drill rig to the entire hammer body. It also typically houses a check valve.
  • Check Valve: Located in the top sub, this valve prevents water or debris from entering the hammer’s internal mechanism when the air supply is cut off.
  • Outer Casing (Cylinder/Hammer Casing): The robust outer shell of the hammer that houses and protects all internal components. It’s designed to withstand immense internal pressure and external abrasive forces.
  • Internal Cylinder: Sits inside the outer casing and guides the piston’s movement. It plays a crucial role in directing the airflow to control the piston’s reciprocating motion.
  • Piston: Often referred to as the “heart” of the hammer, the piston is a precisely machined component that moves rapidly up and down. Compressed air acts on the piston’s surfaces, causing it to strike the anvil (or striking face of the bit) with high force.
  • Air Distributor (Valve/Rigid Valve): This component controls the flow of compressed air to different chambers within the hammer, regulating the piston’s movement and ensuring efficient cycling.
  • Drive Sub (Chuck/Bit Sub): Located at the bottom of the hammer, this part transmits the rotational torque from the outer casing to the drill bit. It also securely holds the drill bit in place.
  • Bit Retaining Ring/System: A mechanism (often a retaining ring or pins) that secures the DTH drill bit to the drive sub, preventing it from detaching during operation.
  • Seals and O-rings: Numerous seals and O-rings are strategically placed throughout the hammer’s structure to prevent air leaks, maintain internal pressure, and keep out contaminants, ensuring efficient operation.
