Dear all,
For a project oriented at low-income, isolated mountain dwellers in northern patagonia, I have been looking at ready-made, low cost peltric sets, or the possibility to import or have built Induction Motor Controllers. Typical parameters are 1-5 l/s and 30 to 100 m head. The equipment has to be low cost, low maintainance and robust, and involves a significant component of technology transfer to the rural dwellers who must be able to maintain their equipment. I have recently come upon the following chinese sets, who feature a permanent magnet alternator, a controller and a dump load (integrated in the base). http://www.maqchin.com/maqchin/pages/maquinaria_china_ltda_productos_centrales_hidroelectricas.htm models of interest are XJL 13-2 x 4.5 (750 W) and XJL 1 x 3.0 (3000 W) In the model I could examine, the rotor was a relatively crudely built (unpolished) turgo. The nozzle is huge and it is geared towards lower heights and bigger flows. I am trying to get the parameters of the rotational speed etc. * does someone have more data and a practical experience with those sets? lessons learned? * any experiences into adapting this equipment to higher heads/lower flows? Thank you, and best regards Max Klohn Puerto Varas, Chile ------------------------ Yahoo! Groups Sponsor --------------------~--> Make a clean sweep of pop-up ads. Yahoo! Companion Toolbar.
