摘要
通过对沙浆泵接力输送和水泵与储料罐组合输送两种深海采矿输送方法进行分析,可知采用沙浆泵对矿石流体进行接力输送的方法,沙浆泵容易磨损破坏,安装维护困难;而水泵与储料罐组合的输送方法在理论上具有扬程高,输送量大,能长期可靠地工作,当应用于深海硬管采矿系统时,输送设备的主水泵和主要动力设备安装于采矿船上,相对于深海工作,在技术上易于实现,工作可靠,操作和维修方便。并对四种输送系统参数进行分析,水泵与储料罐组合的输送方法在理论上可行,采用现有技术容易实现,是一种具有应用前景的深海采矿输送方法。
Theoretically speaking, the pump-vessel combined ores lifting method has such advantages as high head, large ores lifting capacity and long-term working reliability. When applied to the deep-sea rigid pipe mining system, the main pump and power equipment installed on the mining ship are more convenient to operate and maintain. According to Bernoulli' s equation and two phases hydrodynamics theory, the ores lifting equipment parameters have been calculated and analyzed. It is known that the pump-head of 1 000 m sea mining system is 124 - 172 m and that of 5 000 m sea mining system is 652 - 760 m, and it is known that the pump-vessel combined lifting method is feasible in both theory and practice. Therefore it is an ideal ores lifting method for the deep sea rigid pipe mining system.
