Developing a High Efficiency, Ultra-Low Cost Zero-Carbon Pump

世界上大约10%的电力消耗在泵送流体上。水分配占这一电力需求的大部分。目前，我们依赖于电动和燃油驱动的泵，这些泵的资金和运营成本对环境和经济都不利。液压柱塞泵（HRPs）可以作为世界上效率最高的发动机之一（60-70%），并提供一种零碳的抽水方法来帮助解决这个问题。液压柱塞泵通过循环启动和停止流动来集中流水的力量，产生压力波。这些压力波被捕获在一个压力室中，它们的能量被用来将一部分水泵上坡。这意味着水泵不需要电力或燃料来运行，使它们成为最环保的水管理形式之一。用于驱动系统的压力波的力量意味着泵必须由非常耐用的材料组成。传统上使用的是碳钢或铸铁，但这使得泵的制造成本很高（带有4英寸进气管的HRP的RRP为6000英镑），生产速度慢，运输困难。塑料HRPs已经被制造出来，但只适用于较小的泵尺寸（< 2”）。该项目的目标是利用新的制造技术和复合材料创造一种高效、超低成本的HRP。复合HRP设计为易于伸缩（从2英寸到12英寸），当与HydroHammer的HARP系统（HRP的物联网控制器）结合使用时，将使其能够在水管理中部署，最大限度地提高其脱碳效果。首个复合HRP已成功研制并进行了现场试验。该项目将建立和发展复合材料设计的效率，最终目标是展示一种可制造的4英寸HRP，效率为70%，成本低于1000英镑。这一创新将使hrp的大规模部署成为可能，以加强水电、农业和家庭用水的供应并使其脱碳。

Around 10% of the world's generated electricity is consumed in pumping fluids. Water distribution accounts for the majority of this power requirement. Currently, we rely on electric and fuel-driven pumps whose capital and operating costs are environmentally and financially detrimental. Hydraulic Ram Pumps (HRPs) can act as some of the most efficient engines in the world (60-70%), and offer a zero-carbon method for pumping water to help solve this problem.Hydraulic Ram Pumps concentrate the power of running water by cyclically starting and stopping the flow, generating pressure waves. These pressure waves are captured in a pressure chamber and their energy is used to pump a portion of the water uphill. This means that the pumps require no electricity or fuel to operate, making them one of the greenest forms of water management. The force of the pressure waves used to power the system means the pump has to be composed of very durable material. Carbon steel or cast iron is traditionally used, but this makes the pump expensive to manufacture (the RRP of an HRP with a 4" intake pipe \> £6000), slow to produce and difficult to transport. Plastic HRPs have been created but only for the smaller pump sizes (< 2"). The goal of this project is to create a high-efficiency, ultra-low-cost HRP using new manufacturing techniques and composite materials.The Composite HRP is designed to be easily scaled (from 2" to 12") which, when combined with HydroHammer's HARP system (an IoT controller for HRPs), will enable its deployment across water management, maximising its decarbonising impact. The first Composite HRP has been successfully created and field trialled. This project will establish and develop the efficiency of the composite design with the ultimate goal of demonstrating a manufacturable 4" HRP with 70% efficiency for under £1000\.This innovation will enable the mass deployment of HRPs to enhance and decarbonise hydroelectric, agricultural, and domestic water supply.
