EO Accelerator (Threaded)

The Rebco EO Accelerator is a large coil spring assembly placed between the rope socket and the stem in the tool string. Its purpose is to store energy as line tension is applied at the surface and release it simultaneously when the hydraulic or spring jar fires, significantly increasing the speed and impact intensity of the upstroke blow. The accelerator is most important at shallow depths, where the wireline has very little elastic stretch of its own to help activate the jar. At shallow depths, without an accelerator, the operator may need to apply dangerously high line tensions to activate the jar, risking pulling the wire from the rope socket or breaking the wireline. The accelerator's spring compresses over a distance greater than the jar mandrel travel required to fire, ensuring the jar activates reliably under a controlled line tension. Additionally, the accelerator helps maintain a constant pull on the wireline as the jar opens, preventing premature loss of tension that would reduce impact force. The operator determines the optimal position in the tool string to achieve the best effect. Available in standard threaded connections, 1¼"–2½" OD.

ED Accelerator (RQLD)

The Rebco ED Accelerator is the RQLD quick-lock version of the Rebco EO, delivering the same spring energy storage and impact intensification as the Rebco EO, with Rebco's double-shoulder Quick Lock System connection for faster field assembly. Available in RQLD connections, 1¼"–2½" OD.
