High Air Pressure DTH Hammers

High Air Pressure DTH Hammers manufacturers

Generally, the pressure of high air pressure DTH hammers is about 0.7-1.2MPa, which is suitable for drilling in hard rock and extremely hard rock formations. The characteristics of high pressure DTH hammer are high drilling speed and high drilling quality, but the noise and vibration are very high, so it is necessary to control the noise and vibration. The High Air Pressure DTH Hammers we provide include DHD/QL/MISSION series, The DHD/QL/MISSION series is a valve less type hammers designed for high performance at low operating air pressure. All critical internal components are heat treated under strict control to maximize tool longevity.

High Air Pressure DTH Hammers Industry Knowledge Extension

How can high air pressure DTH hammers be energy efficient?
High air pressure DTH (Down-the-Hole) hammers are powerful drilling tools that use compressed air to deliver a high-velocity, high-frequency impact to the drill bit. While they are known for their drilling speed and efficiency, they can also consume a significant amount of energy. Here are some ways to make high air pressure DTH hammers more energy-efficient:
Select the right hammer: Choosing the right hammer for the job is essential for energy efficiency. Select a hammer that matches the drilling requirements and has a pressure range appropriate for the rock formation being drilled.
Optimize drilling parameters: Optimizing drilling parameters such as rotation speed, feed force, and flushing can significantly impact the energy efficiency of the drilling operation. Reducing the rotational speed and feed force while ensuring adequate flushing can improve drilling efficiency and reduce energy consumption.
Regular maintenance: Regular maintenance of the DTH hammer is crucial to maintain optimum performance and reduce energy consumption. This includes cleaning, lubrication, and replacement of worn parts.
Reduce air pressure: Reducing the air pressure to the minimum level required for the job can help reduce energy consumption. However, this should not be done at the expense of the hammer's performance or efficiency.
Use high-efficiency compressors: Using high-efficiency compressors to supply the compressed air needed for drilling can also improve energy efficiency.

High air pressure DTH hammers pressure control method
High air pressure DTH (Down-the-Hole) hammers are powerful drilling tools that require careful pressure control to ensure efficient and safe operation. There are several methods for controlling the pressure of a high air pressure DTH hammer:
Pressure regulator: A pressure regulator can be used to control the pressure of the compressed air delivered to the hammer. This can be adjusted to maintain a constant pressure within the hammer's recommended operating range.
Throttle valve: A throttle valve can be installed on the air supply line to regulate the air flow and pressure delivered to the hammer.
Pressure gauge: A pressure gauge can be installed to monitor the air pressure delivered to the hammer. This can help ensure that the pressure is within the manufacturer's recommended range and adjust it if necessary.
Control box: Some DTH hammers come with a control box that allows for pressure adjustment and monitoring. This can include features such as digital pressure readouts and pressure control valves.
Drilling parameters: The drilling parameters, such as the feed force and rotational speed, can also impact the pressure required to operate the hammer. Optimizing these parameters can help reduce pressure fluctuations and ensure efficient drilling.

How do high air pressure DTH hammers improve efficiency?
High air pressure DTH (Down-the-Hole) hammers are designed to deliver high-velocity, high-frequency impacts to the drill bit, making them highly efficient for drilling through hard rock formations. Here are some ways in which high air pressure DTH hammers improve efficiency:
High drilling speed: High air pressure DTH hammers can drill through hard rock formations quickly, making them much faster than other drilling methods. This reduces the amount of time required to complete a drilling project, leading to increased efficiency.
Increased penetration rate: The high-velocity, high-frequency impacts delivered by high air pressure DTH hammers result in a higher penetration rate compared to other drilling methods. This means that more drilling can be done in less time, increasing efficiency.
Reduced downtime: High air pressure DTH hammers are durable and designed to withstand the rigors of drilling in hard rock formations. This reduces the need for frequent maintenance and repairs, resulting in less downtime and increased efficiency.
Ability to drill deeper: High air pressure DTH hammers are capable of drilling deeper than other drilling methods, allowing for more thorough exploration of rock formations. This can lead to increased accuracy in mineral exploration or geological investigations, improving overall efficiency.
Versatility: High air pressure DTH hammers can be used for a variety of drilling applications, including mineral exploration, geotechnical investigations, and construction. This versatility means that a single tool can be used for multiple projects, increasing efficiency and reducing the need for additional equipment.
