ACCELERATOR

The LiMAR® Accelerator Sub is designed to enhance upward jarring impact when used in conjunction with the compatible LiMAR® Adjustable Spring or Hydraulic Jar.

The Accelerator Sub incorporates a sliding inner mandrel and belleville spring stack which is housed within a ported housing.

The LiMAR® Accelerator is configured above the Spring / Hydraulic Jar and Stem within a wireline toolstring. An upward pull compresses the spring stack and the energy stored is released as the Spring or Hydraulic Jar reaches the tripping point. At this point the toolstring accelerates rapidly until the top of the jar stroke is reached, creating significant upward impact.
