QYSZ Type Full Hydraulic Drilling Jar
QYSZ type drilling jar is one kind of hydraulic jar that can be used to release the sticking drilling tools. When drilling tools get stuck, with this one-piece up and down hydraulic jar, a powerful force is available to release the tools and promise revert the drilling operation as soon as possible.
When using QYSZ type full hydraulic drilling jar, the operator can do adjustment on the ground(No need to make any change of the torque), the jarring force and the direction can be adjusted. This hydraulic jar is easy operated,more reliable and can be generally used in drilling, coring, fishing and cementing operation.
Working principle
●Upward jarring working principle
Lifting the stem to give the tool a up force, upper damping mechanism structure moving with it, after the oil get enough pressure, then reach a predetermined stroke, it may produce a upper force to release the drill stem.
●Lower jarring working principle
Compared with upper jarring working principle, it is quite different to release the drill stem to produce the pressure, the ways to store the energy are the same as up jarring, finally we will get a downward jarring force to release the sticking tools in the down hole.
