饮用水生产

饮用水生产

无论是地表水还是地下水用于水生产，Danfoss AC驱动器都可以帮助优化过程并降低能源和维护成本。一个典型的应用是对深井泵的控制，其中集成的高级最小速度监视器可确保足够的润滑以保护泵。节省能源是通过根据水位高度选择井来实现的。VLT®AquaDrive还广泛用于海水淡化行业，用于控制入口和高压泵以及与能量回收有关的增强泵。

饮用水分配

饮用水分配

在供水中，饮用水分配通常是最大的能源消费者。同时，25–50％的泄漏并不罕见。通过将水分布分为压力区，通常可以将平均压力降低30–40％。VLT®Aqua驱动器非常广泛地用于增加泵站以调节每个压力区域的压力。集成应用软件功能，例如睡眠模式，干式运行检测，自动能量优化（AEO），级联控制，自动流量补偿和坡道功能有助于简化安装并使其更可靠，降低水锤的风险，控制压力，控制压力和减少能耗。

灌溉

灌溉

随着世界上某些地区的水资源变得稀缺，高效和可持续的灌溉变得越来越重要。这一切都是为了提供足够的水以获得最大的作物产量，而无需使用更多的水和能量。Danfoss AC驱动压力或流速适应实际需求。集成的应用程序软件功能既有助于通过限制压力提高并削减能源消耗来保护管道系统。

减少能源消耗的最终解决方案和一个非常快速的趋势是使用太阳能泵。Danfoss Drives为此目的开发了一个专用的逆变器系列。Vacon®产品范围包括针对此环境和高级软件设计的专门设计的封装，这意味着即使云部分阻止阳光到达光伏面板，也可以操作。

废水管系统

废水管系统

废水管系统的能源优化和SCADA控制也是一个快速移动的趋势。通过使用VLT®AquaDrive的集成贬值功能，可以将泵效率提高15–30％，并大大降低维护成本。deraging功能可防止泵的效率通过增加时钟和扩展泵维护间隔而降低。将交流驱动器与SCADA系统一起使用还提供了可能与雨水溢出有关的管道系统中最大利用量的容量。

减少泄漏和能源消耗齐头并进

减少泄漏和能源消耗齐头并进

水分配系统中使用的能量通常代表整个供水系统总能源消耗的60-80％。通过使用压力区和增加泵站的压力调整压力，您可以实现25–40％的能源节省。同时，您可以将漏水泄漏减少30–40％。

调节网络中的压力也可以提供以下好处：

  • 新管道断裂的量减少了40–55％
  • 降低维护成本以及昂贵的管道和道路维修
  • 细菌的风险有限和自来水污染（浸润）
  • 网络的延长服务寿命
  • 推迟对工厂升级的投资
  • 降低水锤的风险

NETHERLANDS: In 2019, the Zuiderzeeland District Water Board invested in new AC drives for three centrifugal pumps at the Buma pumping station in the town of Rutten. Danfoss partner ENGIE Electroproject was awarded the order to replace the drives and associated tasks. Since then, the Danfoss VACON® AC drives have prevented the Noordoostpolder municipality from flooding.

SOUTH AFRICA: In recent years, South African energy security has been constrained and while macroeconomic steps are in progress to correct this, the continuing unreliability of the country’s electricity supply, together with escalating costs, can affect farming in several ways. This includes operations planning, spoiling of produce, and erratic irrigation schedules. The Development Bank of Southern Africa recognizes South Africa as being a water-scarce country, so energy efficiency in assisting with irrigation is critically important.
