The JQ-YS type two-way hydraulic shock absorber is a shock absorber that can simultaneously slow or eliminate the longitudinal and circumferential vibration of the drill string. The product can maintain normal drilling pressure and torque, thereby reducing the vibration damage of drill bits, drilling tools and ground equipment, and can achieve the purpose of increasing drilling speed and reducing drilling costs.

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.
