 MJ™ SPANG LINK JARS OR MECHANICAL JARS

 PARVEEN Spang Link or Mechanical Jars are used in wireline fishing operations with stems. The weight of stems and jars can be used by operator for jarring by pulling and then releasing wireline. These Jars are available in various sizes and strokes. Force =Mass x Acceleration. Stem weight is fixed but speed can be varied. In jar down action, speed is limited due to limited travel and gravity. Jar of action is more effective as speed can be increased by increasing the spooling speed of wireline unit and using long jars.
