Reverse Circulation Hammers are an important component of drilling equipment, and the following is a detailed introduction to them:
1、 Definition and Working Principle
Reverse Circulation Hammers， The reverse circulation down the hole hammer is a special drilling tool. Its working principle is to drive the hammer body to perform high-frequency reciprocating motion through compressed air or other fluid media, thereby achieving rock fragmentation and drilling. During the drilling process, the fluid medium inside the drill pipe (such as air or water) rises to the surface through the annular gap between the drill pipe and the hole wall, while carrying the drill cuttings to the surface, forming a reverse circulation.
2、 Characteristics and advantages
Efficient drilling: The reverse circulation down the hole hammer has a high drilling efficiency, especially in hard rocks and complex formations.
Reduce drilling debris blockage: Due to the use of reverse circulation, drilling debris is less likely to block inside the drill pipe, thereby improving the continuity and stability of drilling.
Extending the lifespan of the drill bit: The design of the reverse circulation down the hole hammer helps reduce wear and fatigue of the drill bit, thereby extending its service life.
Modular design: Some reverse circulation down the hole hammers adopt modular design, making it easy to replace and maintain the drill bit, improving the flexibility and applicability of the equipment.

3、 Application Fields
Reverse circulation down the hole hammer is widely used in geological exploration, mineral mining, hydrological well drilling, geotechnical engineering exploration and other fields. Especially when obtaining core samples or conducting deep drilling, the reverse circulation down the hole hammer has irreplaceable advantages.
