The jarring delay time is 30s~240s, and the act force can be adjusted according to the lifting force on the ground.

 

Hydraulic Drilling Jar Advantages

 

Upward and downward jarring force can be controlled on ground.

 

Hydraulic structure, stronger impact.

 

The inner cavity is in the pressure relief state during normal drilling, which does not affect the service life of the jarring actuator.
