泵优化降低运营成本

泵优化降低运营成本

泵在整个采矿业务中执行无数任务。通过通过交流驱动器投资性能优化，您可以实现更有效的抽水，更好的设备保护并降低许多不同领域的运营成本。

优化脱水泵滑冰

出于环境和降低成本的原因，许多矿场更喜欢使用电动泵防而不是传统的柴油发动机驱动的泵。当有靠近脱水泵滑动位置的电源时，这是可能的。

电动泵防滑而不是柴油发动机，通常使用交流电动机和驱动器来设置脱水泵的流速。通常，电动驱动的SKID的初始成本高于柴油机驱动的替代方案，但运营成本明显低。较高的初始投资通常会在几个月内很快回收。由于不需要每百小时一次换柴油发动机的油，也无需支付加油卡车和劳动力，因此这可以节省更多的维护和运营成本。

为了用潜水泵脱水，Danfoss AC驱动器执行这些重要任务，并提供这些优势以优化脱水泵的性能：

  • 与直线（DOL）操作相比，可能的泵直径较小
  • 控制水位泵的水位，以消除阀
  • 通过无线电或卫星将数据传输到主站
  • 通过卫星更改软件
  • 干式泵保护
  • 消除泵的成本，因为与阀相比，控制范围更宽，驱动器更宽
  • 当达到所需的水位时，具有PID水平控制和睡眠模式的独立操作。当水平再次上升时，泵不需要外部信号即可重新启动

Danfoss AC驱动器还提供了与所有典型电动机技术的兼容性，例如感应电动机（IM），同步不情愿电动机（Synrm）和永久性磁力（PM）电动机。这种灵活性使您能够通过喜欢的电动机品牌和技术来优化系统。

解决脱水泵防滑挑战

在电动泵上驱动器的共同挑战包括

  • 有限的空间可用。驱动器的尺寸通常会影响泵的大小和成本，以及井的钻井和创造成本
  • 安装了泵的刺激性，尘土飞扬且经常是热的环境

Danfoss驱动器轻松应对这些挑战，并广泛用于许多矿场的脱水泵防滑。它们的紧凑型围墙通常使泵防滑制造商能够最大程度地减少滑雪的尺寸和成本。它们稳健，高的环境温度设计可确保可靠的，长寿的运行时间，即使安装在露水泵上，在露天的脱水泵上，在一个炎热的潮湿的矿场上，带有矿业卡车每隔几分钟就可以踢灰尘。

由于IP66外壳可用于广泛的功率范围，因此很容易将这些驱动器安装在泵上，并具有简单的天气屏蔽层以提供阴影。该解决方案坚固，可靠，仅需要最低维护水平。

80 kW节省的功率归功于南非科洛梅拉矿的变电站热量减少

VLT®驱动器安装在矿山脱水系统上，该系统将水分配给工厂运营以及当地的城镇供水。
