Wireline Spring Jar Wireline Tool String
I. introduction (B)
A wireline spring jar is designed to provide upward jarring during heavy duty fishing operation. It can
guarantee the faultless operation with least maintenance.
Ⅱ.Structure characteristics (C)
The wireline spring jar consists of fishing neck, sleeve, jar stem, pup joint, locking piece, slip, spring,
extension rod, spacer, connecting sleeve, pressing sleeve, adjusting screw, lower sub, disc spring, etc..
When the jar is closed, the slip on the jar stem will stretch and clamp on the extension rod under the
function of spring. When lifting, the jar stem will drive the slip to pull the extension rod and squeeze the
disc spring to reserve energy. When the jar stem runs for some stroke, the slip will be squeezed by the
pup joint and disconnect with the extension rod. Then the energy of disc spring will release immediately
to finish the jarring effect.
