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

垂直和水平离心泵在整个工业中使用，用户经常被迫从供应商的标准泵系列中选择最适合给定应用的泵。多达50%的泵没有在最佳效率点运行，25%的能源效率是常见的。在理想的情况下，泵的叶轮和壳体将根据每个特定的泵的应用进行设计和制造。石油化工行业的液体硫泵是一个特别苛刻的环境，需要高可靠性和鲁棒性。现在人们要求提高能源效率。项目有两个关键目标，首先，开发设计和生产流程，使最先进、最高效的定制离心泵能够在更短的交货时间内以更低的成本设计和生产给最终用户。其次，将该技术应用于制造一种高效率、高可维护性和高可靠性的用于制硫市场的离心泵样机。然后，Amarinth将在许多其他泵应用中使用设计和快速模具技术，并将其作为与竞争对手的关键区别，并进一步提升其在短时间内提供高可靠性泵的品牌形象。主要的好处集中在两个项目领域。能够制造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95%的泵生命周期成本是能源成本时，这代表着巨大的节省。更少的能源使用意味着二氧化碳的减少。硫泵的成功开发将确保工厂更高效、可靠地运行。如果工厂经历紧急停机和硫固化，泵的设计可以快速恢复和修复，具有经济、健康和安全优势。在25%的市场渗透率下，英国泵组每年可节省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%.
