震击加速器是为上击器增加震击动能而设计的井下打捞震击工具。因此它必须和CSJ型超级震击器或YSJ型液压上击器联合使用。它的主要作用是当上击器在自由冲程时，对上击器的上部起加速作用，从而增加了上击器向上的震击力量。震击加速器实质是一个液压式的液体弹簧，由于它的特有作用，不仅可以增大向上的震击力量，而且能使震击直接打在落鱼上，还能减少损坏钻具和打捞工具。
The ZJS type jar intensifier is a down hole fishing jar designed to increase jarring energy to up jar .Therefore ,it must be run in conjunction with CSJ type super jar or YSJ type hydraulic up jar .Its function mainly is to supply acceleration to the upper end of the jar during the free jarring stroke .With a special function ,the intensifier is essentially a fluid spring which not only can accelerate the up jarring action but also make the jarring action directly to strike on the fish and reduce damages to the drill tool and fishing tool .
