Hydraulic Jar Operation & Mechanism

The tripping (check also: Tripping pipe procedures) action of a hydraulic jar depends on energy stored in the stretch of the string. When an overpull is applied, the stored energy is released, and the jar fires.. A fluid metering system is used to delay the tripping of the hydraulic jar. As overpull is applied to the work string, the string is stretched.

The Ultimate Guide to Hydraulic Cylinder Seals

A static piston seal sits within the piston with the rod running through it. The pressure from the rod creates an impermeable seal that prevents hydraulic fluid from being pushed through to the other side of the piston. This is especially important in single-action pistons, which only have hydraulic fluid on one side of the piston.
