6 FAQs about [Jinhua hydraulic rock drill effect]

What is double damping system in hydraulic rock drill?

As a technological innovation of high-power hydraulic rock drill, double damping system has a very important effect on impact performance. The double damping system is a floating mechanism. The characteristics of the floating mechanism have an important influence on the impact energy, frequency, and power of the hydraulic rock drill.

Does QD FD affect hydraulic rock drill output power?

The effects of different the combination ( Qd, Fd) on impact performance, including impact energy and frequency, are researched. These influences determine the output power of the hydraulic rock drill.

Do damping flow and feed force affect impact performance of Rock Drill?

The results show that damping flow and feed force have great influence on impact performance of the rock drill. The maximum drilling power is obtained at the combination ( Qd = 8 L·min −1, Fd = 16.25 kN), while the other parameters only obtain lower drilling power.

How does hydraulic rock drill reciprocating work?

The impact piston of hydraulic rock drill reciprocating moves under the action of hydraulic oil. When it reaches the limit position of the front end, it impacts the shank and generates the incident stress wave. The incident stress wave is transmitted to the rock through the shank, drill rod, and drill bit, and the rock is broken.

Does a double damping system improve energy absorption during rock drilling?

Conclusions The floating characteristics of internal components of the double damping system are analyzed, which can better solve the problem of energy absorption during rock drilling, but also has negative effects on the utilization of impact energy. The negative effects become obvious with the increase power of rock drill.
