YSJ Type Z Oil Jar

YSJ Type Z Oil Jar

YSJ Type Z Oil Jar

YSJ type hydraulic up jar is usded to be free from drilling sticking  ,through hydraulic principle, by means of elastic petential produced from drill tool elastic deformation. Once the elastic potential energy is released, it would produce a large up striking load to reach a purpose of fishing and coring. It features easy structures, strong jarring force, easy to return, convenient operation. If it is used with ZJS type jar intensifier, it may gain better jarring effect.

working principle
The key principle is : the piston moves up and make hydraulicking so that it makes enough time to make drill tool to save energy. With the piston continue to move slowly to releasing bore, after the binding of hydraulic oil is released, elastic potential is released by drill tool saved , immense dynamic loading is passed to drill tool due to jar pad ‘s hitting on the bottom of up jar  cylinder liner. A desire return mechanism   makes a reciprocating jarring action.
