SH—54型液动冲击器,于1983年12月份,由地矿部探矿工程装备工业公司组织通过鉴定后,我局1984年有6台钻机推广应用。在推广使用中,遇到泵压过高的问题,即泵压在40公斤/厘米~2以上,不能正常钻进。这就给推广使用冲击器带来一定的困难。经分析研究后,改进使用技术方法,泵压便大幅度地降了下来,从而使该冲击器得以顺利地推广。
SH-54-type hydraulic impactor, in December 1983 by the Ministry of Geology and Mineral Resources Exploration and Production Equipment Industry Corporation passed the appraisal, the Bureau in 1984, six rigs to promote the use of. In the promotion of use, encountered pumping too high pressure, that is, pump pressure at 40 kg / cm ~ 2 above, can not be normal drilling. This will promote the use of impactor to bring some difficulties. After the analysis and study, to improve the use of technical methods, pumping pressure dropped significantly, so that the impact of the impact of the device can be successfully promoted.
