Product Description

 
Product Description
The QYSZ type drilling jar is a kind of hydraulic jar that can be employed to release the drilling tools that are stuck. With this one-piece double acting hydraulic jar, a powerful force is available to the operator and ensures that normal drilling operations can be resumed as soon as possible.  
 
When operating the QYSZ type hydraulic jar, the operator can make adjustments to the jarring force and direction on the ground without the need to adjust the torque. The QYSZ jar is reliable and can be operated with ease. It can be applied widely in drilling, coring, fishing and cementing operations.   
 
 
Working principles 
Upward Jarring
Lifting the drill stem gives the hydraulic jar an upward force, moving the upper hydraulic mechanism along with it. This generates an increased pressure in the working fluid. Thus, when the jar reaches a predetermined stroke, the fluid pressure is released, creating an upward jarring force, releasing the stuck drill stem.   
 
 
Downward Jarring 
Downward force is applied on the hydraulic jar, to create pressure in the working fluid of the lower hydraulic mechanism. When the jar reaches a predetermined stroke, the fluid pressure is released, creating a downward jarring force to release the struck drill tools.
