Heavy-Load Accelerator

The Heavy-Load Accelerator is an auxiliary tool designed to enhance the impact of a jar. Typically installed above the jar, it improves jarring speed and impact intensity through energy storage and instantaneous release, increasing the success rate of downhole jarring operations. The Heavy-Load Accelerator uses a stack of Belleville springs to accumulate energy. When the jar fires upward or downward, the spring stack instantly releases its stored energy, providing additional acceleration and increasing the jar's impact force.

Product Features

Enhanced Jarring Effect: Instantly releases a high load to increase the jar's impact intensity and free a stuck tool.

Simple Structure, Easy Maintenance: Optimized design reduces downhole failures and extends service life.

Full-Bore Design: Allows for downhole reverse circulation, improving operational flexibility.

High Tensile Strength: Can withstand large tension and loads, adapting to complex well conditions.
