III. Structure Characteristics

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.
