Hydraulic rock drill vs pneumatic rock drill

Pneumatic Rock drills and hydraulic rock drills are both drilling machines widely used in mining, tunneling and other engineering fields. Hydraulic rock drills have obvious advantages over pneumatic rock drills.

Comparison of worKing principles of hydraulic rock drill vs pneumatic rock drill

Hydraulic rock drills use a well-designed oil circuit system to generate greater impact force than pneumatic rock drills, and have higher accuracy, and are not prone to accidental damage to the surrounding environment and equipment
Pneumatic rock drills use high-speed rotating airflow to generate impact force for rock drilling, and their accuracy and stability are not as good as
Hydraulic rock drills have relatively high energy efficiency because the hydraulic system can accurately control force and speed, reducing unnecessary energy waste
Pneumatic rock drills have low energy efficiency because there will be greater energy loss in the process of converting electrical energy into compressed air

 

Comparison of advantages of hydraulic rock drill vs pneumatic rock drill

Hydraulic rock drills have high working efficiency: using hydraulic oil as power, they can generate greater impact force and break rocks faster and deeper.

Pneumatic efficiency is slow: the power source of pneumatic rock drill is only compressed air, so the impact force generated is smaller than that of hydraulic rock drill.

 

 

High hydraulic safety factor: personnel can control drilling on the trolley operating table, with higher safety performance, and the harm to operators can be reduced by more than 60%; when working continuously, the fatigue of the operator is lower than that of pneumatic rock drill.
High pneumatic risk: high work intensity, no good safety protection measures for operators, and high risk.
Hydraulic energy saving and environmental protection: high energy utilization rate, and less noise and dust pollution
Pneumatic noise is large: noise and dust pollution are large, the impact on operators and the environment is large, and the labor intensity is high
The advantages of hydraulic rock drills are obvious. Although the price of pneumatic rock drills is relatively low, they cannot be compared with hydraulic rock drills in terms of efficiency and quality of rock drilling work. Especially in the fields of mining and modern construction that require high efficiency, high precision and environmental protection. Therefore, when actually choosing to purchase rock drilling equipment, factors such as its scope of application, use environment, and use effect should be considered to decide.

 

With the development of the industry, the application prospects of hydraulic rock drills are broad, and it is expected that they will occupy a more important position in future mining and construction.
