YJQ  Type Jar Accelerator

 

 

YJQ  Type Jar Accelerator is a down hole fishing jar designed to increase jarring energy to up jar. Therefore, it must be run in conjunction withsuper jar orhydraulic up jar.

 

 Its function mainly is to supply acceleration to the upper end of the jar during the free jarring stroke.

With a special function, the intensifier is essentially a fluid spring which not only can accelerate the up jarring action but also make the jarring action directly to strike on the fish and reduce damages to the drill tool and fishing tool.
