Introduction:
The bidirectional hydraulic jar utilizes a precision hydraulic valve to control the flow rate of damping oil, causing the work string to undergo elastic deformation and then release energy. This converts elastic potential energy into kinetic energy in both upward and downward directions. The powerful impact force generated during the instantaneous release acts on the stuck point, achieving the goal of freeing the stuck tool.
Features and Benefits:
★ High-temperature composite sealing system, offering long lifespan and high reliability.
★ The hydraulic valve features an all-metal structure.
★ The damping system includes a pressure-balanced design, extending the lifespan of the seals.
