Solar Steam Vacuum Pump

想象力工厂将现代太阳能技术与蒸汽时代的一个简单的传统水泵结合在一起。太阳能灌溉将由冷凝式蒸汽泵和太阳能蒸汽发生器相结合提供。蒸汽真空泵坚固耐用，无活塞，运动部件很少。这些泵可以追溯到最早的蒸汽时代，并在20世纪被广泛用于抽矿、船底和便携式挖掘工作，它们非常适合抽出脏水。蒸汽被用来直接对抽出的水施加压力，以提供正的排量；冷凝的蒸汽产生真空，将水吸进泵中。真空能把水吸到约30英尺的高度。撒哈拉以南非洲地区拥有丰富的太阳能。这将被用来从湿管锅炉中产生低压安全蒸汽。复合抛物面太阳能热集中器将把热量集中到低成本的太阳能真空管上。这将提供热量来产生蒸汽。复合抛物面太阳能热集中器和太阳能真空管是众所周知的、可靠的固态设备；两者都重量轻、携带方便。该项目的目标是将这两项成熟的机械技术结合在一起，以制造一种现代太阳能蒸汽真空泵设计；适合于发展中国家的本地化低成本生产。想象力工厂能够利用激励-通过流动-自由-慈善的人才，他们擅长在发展中国家建立培训、当地制造和生产工厂。我们还将从乐施会的国际公认的水计划中获得建议。想象力工厂有许多创造性的方法来满足这种泵激进的成本目标。回收和再利用的灭火器和其他使用过的压力容器被用作泵的核心部件。设计意图将从一开始就对成本敏感，泵将以套件的形式提供，适合于发展中国家的简单生产和维修。想象力工厂团队包括成功打破并保持蒸汽动力汽车陆地速度纪录的英国蒸汽汽车挑战赛的成员。蒸汽和工程经验是根深蒂固的。

The Imagination Factory is bringing together modern solar technology with a simple legacy pump from the steam era. Solar powered irrigation will be provided by a combination of a condensing steam pump and a solar steam generator. Steam vacuum pumps are robust, piston-less and have very few moving parts. These pumps date from the earliest days of steam and were widely used into the 20th century for pumping mines, ship bilges and for portable excavation work, they are well suited to pumping dirty water. Steam is used to apply direct pressure on the pumped water to provide positive displacement; condensing steam creates a vacuum to draw water into the pump. A vacuum is able to draw water to a height of ~30ft . Sub-Saharan Africa receives an abundance of solar energy. This will be used to create low pressure safe steam from a wet tube boiler. A compound parabolic solar thermal concentrator will concentrate heat onto a low cost solar vacuum tube. This will provide the heat to create the steam. Compound Parabolic solar thermal concentrators and solar vacuum tubes are well understood, reliable, solid state devices; both are light weight and portable. The ambition for this project is to combine these two well established pieces of mechanical technology in order to manufacture a modern solar steam vacuum pump design; appropriate to localised low cost production in the developing world. The Imagination Factory is able to draw on the talents of Motivation - Freedom through Mobility - charity who are skilled in setting up training, local manufacturing and production plant in the developing world. We will also receive advice from Oxfam's internationally recognised water program. The Imagination Factory has a number of creative approaches to meet the aggressive cost target for this pump. Recycled and repurposed fire extinguishers and other used pressure vessels are intended as the core pump components. The design intent will be cost sensitive from the outset, the pump will be available in kit form appropriate for simple production and servicing and maintenance in the developing world The Imagination Factory team includes members of the successful British Steam Car Challenge that broke and still holds the land speed record for a steam powered car. Steam and engineering experience are embedded.
