辽宁54型液动冲击器自78年4月开始研制，79年投入生产试验以来，先后在三个矿区，八个钻孔中使用，钻进791个回次，进尺1020,67米。使用结果表明，54型冲击器工作基本稳定，适应性较广，可在10—15公斤/平方厘米泵压下连续工作，冲击功1—3公斤·米，冲击频率800—2200次/分，适用于合金冲击回转钻进，以及小口径金刚石回转冲击钻进。在七级花岗闪长岩中采用金刚石回转冲击钻进，台月效率比金刚石回转钻进提高148％。现将其基本情况介绍如下：
Since its commencement in April 78, Liaoning Type 54 hydraulic impactor has been in production since 79 and has been used in three mining areas and eight drilling holes for a total of 791 rounds and 1020 and 67 meters of footage. The results show that the 54 type impactor works basically stable with wide adaptability and can work continuously under the pump pressure of 10-15 kg / cm 2 with an impact energy of 1-3 kg · m and an impact frequency of 800-2200 times / Suitable for alloy impact rotary drilling, and small diameter diamond rotary impact drilling. In seven grade granodiorite using diamond rotary impact drilling, Taiwan and the moon efficiency than the diamond rotary drilling increased 148%. Now the basic situation is as follows:
