Introduction:
The bidirectional hydraulic jar utilizes precision hydraulic valves to regulate the flow rate of damping oil, enabling the work string to undergo elastic deformation and subsequently release energy. This process converts elastic potential energy into kinetic energy in either the upward or downward direction. The instantaneous release generates a powerful impact force applied to the stuck point, achieving the objective of freeing the stuck tool.
Features and Benefits:
★ The high-temperature composite sealing system boasts a long lifespan and high reliability.
★ The hydraulic valve is constructed with an all-metal design.
★ The damping system incorporates a pressure-balanced design, which extends the lifespan of the seals.
★ The temperature and delay time can be precisely calibrated according to user requirements.
