Amarinth - a new rapid prototyping production technique for centrifugal pumps culminating in the production of a bespoke pump for the sulphur production industry

立式和卧式离心泵在整个工业中使用，用户经常被迫从供应商提供的标准系列泵中选择最适合特定应用的泵。多达50%的泵没有在其最佳效率点运行，25%的能源效率低下是很常见的。在理想的情况下，泵的叶轮和外壳将根据每种特定的泵应用进行设计和制造。石油化学工业中的液体硫磺泵送是一个特别苛刻的环境，需要高可靠性和健壮性。人们现在要求提高能效。该项目有两个主要目标，首先是开发设计和生产流程，使最先进和最高效的定制离心泵能够在更短的交货期内设计和生产，并降低最终用户的成本。二是将该技术应用于硫磺生产市场，研制出高效、高可维护性、高可靠性的离心泵样机。然后，Amarinth将在他们的许多其他泵应用中使用设计和快速工具技术，并将其作为区别于竞争对手的关键优势，并进一步提升其在短交货期内提供高可靠性泵的品牌形象。主要受益集中在这两个项目领域。能够制造设计为以最佳效率点运行的泵可以为最终用户节省10%-25%的能源，当泵生命周期成本的95%是能源成本时，这代表着巨大的节省。更少的能源消耗意味着二氧化碳的节省。硫磺泵的成功开发将确保工厂更高效、更可靠地运行。如果工厂发生紧急关闭，硫磺固化，泵的设计允许快速恢复和维修，这具有经济、健康和安全优势。在市场渗透率为25%的情况下，英国泵队每年可节省875GWH的能源。Amarinth的目标是5%。

Vertical and horizontal centrifugal pumps are used throughout industry and users are oftenforced to select a best fit pump for a given application from a standard range of pumps fromsuppliers. As many as 50% of pumps do not then run at their Best Efficiency Point and energyinefficiencies of 25% are common. In an ideal world the impellor and casing of a pump wouldbe designed and manufactured to each specific pump application. The pumping of liquidsulphur in the petro-chemical industry is a particularly aggressive environment requiring highreliability and robustness. Energy efficiency is now being demanded. Project has two keyobjectives, firstly the development of a design and production process to enable the mostadvanced and efficient bespoke centrifugal pumps to be designed & produced in shorter leadtimes and at less cost to end users. Secondly this technology will be applied to create aprototype centrifugal pump for application into the sulphur production market with highefficiency, high maintainability and high reliability. Amarinth will then use the design andrapid tooling techniques in many of their other pump applications and use it as a keydifferentiator from their competition and further their brand image of delivering highlyreliable pumps in short leadtimes. Main benefits are focused on the two project areas. Beingable to manufacture pumps designed to operate at their Best Efficiency Point can offer endusers10 – 25% energy savings and when 95% of pump life cycle costs are energy costs, thisrepresents a huge saving. Less energy usage means CO2 savings. Successful development ofthe sulphur pump will ensure plant runs more efficiently and reliably. If the plant experiencesan emergency shutdown & the sulphur solidifies, the pump design allows rapid reinstatement& repair which has economic and health and safety advantages. UK pump fleet energysavings of 875GWH/year could be expected with 25% market penetration. Amarinth has atarget of 5%.
