The JZY hydraulic shock absorber uses the internal compressible liquid to absorb or reduce the impact and vibration load on the drill bit and drilling tool during the drilling process, protect the drill bit teeth, bearings and drilling tool, and extend the life of the drill bit and drilling tool.

The JZ mechanical shock absorber is a shock absorbing tool that plays a longitudinal shock absorption role when drilling with a tooth wheel drill bit or an abrasive core drill bit. It absorbs or slows down the longitudinal vibration and shock load of the drill string during drilling, thereby maintaining normal drilling pressure, extending the service life of the drill bit, protecting drilling tools and surface equipment, reducing drilling costs, and improving drilling efficiency.
