8 Inch DHD380 DTH Hammer

 

An 8 Inch DHD380 DTH Hammer is a specialized drilling tool used in various applications such as mining, quarrying, construction, and geotechnical drilling.

 

Application area: 8 Inch DHD380 DTH Hammer is extensively utilized in the engineering hole-making processes in the industries of metallurgy, coal, chemical, mining, water conservation, hydropower, highway, railway, and national defense.

 

Performance characteristics of 8 Inch DHD380 DTH Hammer:

1. Breaking rocks uses less energy and has a high single-impact energy.

2. The piston and drill bit have similar weight ratios and are efficient for a long period. Enhancing rock-crushing effectiveness and extending the life of drilling equipment are both advantageous.

3. The repetitive crushing of rock is decreased and the central exhaust has an excellent slag discharge effect.

4. It features a straightforward, dependable internal structure that is simple to put together and take apart, has few faults, and is easy to maintain.

5. The 8 Inch DHD380 DTH Hammer includes a check valve tool that allows it to pierce the water with holes.

6. When working, it is always at the front end of the hole, and the drilling depth has no bearing on how much impact energy is transmitted.

 

 

The 8 Inch DHD380 DTH Hammer with a spline function refers to a specific design feature related to the hammer's connection mechanism. Here's some information about the spline function:

 

Spline Function: A spline function in the context of a DTH hammer refers to the type of connection between the hammer and the drill bit. It utilizes a spline design on the hammer's shank and a corresponding spline socket on the drill bit.

 

Connection Stability: The spline function provides a robust and secure connection between the DTH hammer and the drill bit. The spline design ensures a positive engagement, minimizing the risk of slippage or rotational movement during drilling operations.

 

Torque Transmission: The spline function facilitates efficient transmission of torque from the hammer to the drill bit. This allows the energy generated by the hammer's impact mechanism to be effectively transferred to the bit, resulting in optimal drilling performance.

 

Alignment: The spline function helps in maintaining alignment between the hammer and the drill bit during drilling. It ensures that the impact forces are evenly distributed, reducing the likelihood of premature wear or damage to the connection interface.
