Introduction:
The hydraulic accelerator is designed to be used in conjunction with a super jar. During operation, it is connected above the upward-impact jar (with 1 to 3 drill collars recommended in between) to achieve a greater upward impact force. It features a compact structure, reliable sealing, and high strength.
Features and Benefits:
★ When used in combination with a drilling jar, it significantly enhances the upward impact force.
★ Compact and robust construction for reliable, long-lasting performance.
★ Advanced sealing design for high-pressure stability and reliability.
