Products Description LEANOMS
A typical drilling instrument in the mining, construction, and oil and gas exploration industries is the down the hole hammer. It's an impact drilling technology that drives strong impact forces into the dth hammer bit with compressed air, enabling it to swiftly and effectively penetrate a variety of rock forms.
Compressed air is transported into the DHD hammer via the drill string as its basic mechanism of operation. The air pressure is transformed inside the hammer into a series of quick hits that are sent to the drill bit. The rock is crushed by this collision, creating a borehole.
Products advantage LEANOMS
A key feature of the DHD hammer is its ability to provide excellent penetration and drilling efficiency. Due to the hammer's repetitive impact action, drilling tasks can be completed faster and at a lower cost.
DHD hammers come in several different sizes to meet different drilling needs. The diameter of the hole a DHD hammer is able to drill depends on its size. In addition, different DHD hammer models may have unique design elements to maximize performance in specific drilling environments or rock types.
Products Sizes & types LEANOMS
DHD hammers, also known as down the hole hammer drilling DHD hammers, are commonly used in water well or mine drilling operations. They are available in a variety of sizes and feature configurations to meet different drilling needs. Here are some common sizes and types of DHD hammers:
By sizes:
DHD3.5 hammer: Usually used for small-diameter drilling applications.
DHD340 hammer: Suitable for medium-sized drilling projects.
DHD350, DHD360 and DHD380 hammers: Are larger sized hammers for heavy-duty drilling tasks
By gas distribution:
Hammers with footvalves: Simplified design without internal valve system, making them more reliable and easier to maintain.
Hammers without footvalves: Contains internal valve system for improved performance and efficient flushing of drill cuttings.
Drill Bit Face Shape:
Convex Face Design: Applicable to all rock formations, especially in medium-hard and uniform rock formations. The blasthol e deviation is small and the slag removal effect is good.
Flat Face Design: Applicable to drilling very hard rock formations and highly corrosive rock formations under high wind pressure. At this time, the drilling speed is faster and the body is less abraded.
Carbide Button&Shank Styles LEANOMS
Carbide Button Styles:
Ballistic Buttons: Designed for fast drilling in hard and abrasive formations, providing high penetration rates.
Spherical Buttons: Optimized for drilling in extremely hard formations, delivering excellent penetration rates.
Bit Shank Styles:
DHD Standard Shank: Commonly used and compatible with various drill rigs.
SD Shank: Shorter and lighter design, suitable for limited space drilling operations.
Mission Shank: Designed for specific drilling rigs, offering a reliable connection and efficient energy transfer.
