摘要
ＣＳＪ型超级震击器采用机械和液压组合设计，通过锥体活塞在液压腔内的往复运动实现向上震击的功能。在阐述震击器的结构设计和工作原理之后，着重介绍了震击器的规格系列、参数、操作规程、维修保养和地面试验等使用说明。这种震击器与ＹＪＱ型震击加速器一同使用，可获得更显著的效果。
Model CSJ super fishing jar adopts mechanical and hydraulic combined design and carries out upward jarring by the reciprocting motion of the conical piston in the hydraulic cylinder.After an introduction to the design features of the jar,the specifications,parameters,operating rules,maintenance and surface test of the jar are listed and expounded.By using this jar together with Model YJQ jar accelerator,more remarkable effect can be obtained.
