price: contact company for price

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.
