Pneumatic hammer for petroleum drilling

 

Abstract:

 

Pneumatic hammer for petroleum drilling is the new type of special tool for punching drilling driven by compressed air. It has advantages of high impact energy, fast punching, long service life, good deslagging effect, being user-friendly and reliability.

 

Application:

 

During drilling, it can drill holes for rocks with different hardness and also drill blast hole, exhaust outlet and air vent for various mine hard rocks.

 

Characteristics:

 

1. Simple structure, easy to maintain, with less fault.

 

2.  High impact power, with good energy transmission and fast rock drilling.

 

3.  All parts are specially treated, with good hardness, wearing resistance and long life.

 

4.  As to the drive chuck, the thread of both ends connects with outer casing, which makes the removal of drill easy.

 

5.   When lift off hole bottom, it can stop punching automatically while blowing with high air volume to deslag.

 

6.   It has waterproof anti-kickback device.

 

7.  Center exhaust, with good deslagging effect, reducing repeated rock crushing.
