Bladeless fluid machines, basic information

Bladeless fluid machines (BFM) are principally new rotocure.

They operate inall common viscose liquid mediums

(fluid and gas) benefiting from until now unknown effect of boundary layers. They arealso known as „Bladelees turbines“ or „Turbines SETUR“.BFM are refered to as the invention of Czechoslovak authors, being wholly unique, far-reaching technical, economic and scientific impact.BFM are characterized by : - extremely simple construction (consisting of rotary components), therefore resulting in low prices and high

reliability (virtually there is nothing to be damaged)- high efficiency even when changes to input media parameters are involved, wihtout the neccessity to regulateor change the geometry of the machine.

- ability to deal with minimum compressive strenght and very low flows,- ability works like pump or supercharger - compressors 

There are two type of BMF: - BFM with rocking axis (rotary rolls on the inner surface of a stator)- BFM with fixed axis (rotary is placed in double bearings, with no connection to stator)

BFMs are protected by patents in 20 advanced world countries. There are, for example, 3 European patents. A development which bringsgraet knowledge and a wide range of applications along with the possibility of further patent protection is being carried out.

 A mathematical model for BFMs with fixed axis has been created and basic physical formulas for gas medium have been described. At present, two products are being developed: small water power station DVE (see other side) and car-brushes.Different types of brush devices (cleaning glass and dishes, animal purgation), sprinklers, humidifiers and flow limiters derive benefit from thefollowing unique characteristics of BFMs with rocking axis. That is precessional movement of the axis resulting from rolling of the rotary onthe inner surface of the stator. This motion can be expressed as a mechanical power, where micro-oscillations increase the cleaning effect of brushes, enabling application of sprinklers, humidifiers, air aerators, cleaning nozzles, homogenizers, stirrers, etc. They are also used inaquatic and pool vaccum cleaners with rotating power brushes, turbo brush attachments to vaccum cleaners, as a back-up power supplyoperated by water supply system and other applications.

Other applications in preparing include: - Water powered tooth-brush using waterflow from tap, combined with water jet.- Steam and gas turbine. Driving turbine for turbo blower.- Semi-closed cycle gas-liquid low pressure turbines ( e.g . Rankin, Kalina). Will enable more effective production seat power control energy

from combustion biomass, outlet warm from steam power station, energy thermal gradient in different depths consumes and oceans. 

- Sprinklers with nozzle extensions ( underground)- Flow power station for sea water flow ( riverine flows). 

For the products mentioned above, we search partners who have interest in manufacturing and sale, development cooperation and funding of the projects – mainly patent protection and research. Thanks to internationally valid patents, these investments will be protected over the longterm, unique engineering design being quite incommutable.

Small hydroelectric power stations with bladeless turbine SETURPatent protection: EP 1015760 B1, US Patent 6, 139.267. RU No 2185525

Small hydroelectric power stations with bladelees turbine SETUR is characterized by the following features:- They are simple, reliable and mainly cheap, due to their unigue patent protected construction.- They are effectively using low flow (4,0-500 l/s) and small to middle falls (0,6,-25m). - Turbines have good efficiency up to 75% for rotary Ǿ 120 mm! They don’t need regulation.- They work reliably in a range of 50 to 120% nominal flow.- Self regulation characteristics. After unloading the turbine flow decreases to 50% and rotation speed increases to max. 150% nominal.- They are not affected by the changes in the fall or changes in the water levels. Damage of blades is not possible.- They are suitable for places without electrical network, which can be replaced by them using electric chopper and accumulator - Simple installation. It is not necessary to build-up big dikes.They can work on every streamlet or small river. Water supply can be provided

as movable by inflexion hose. DVE 120 and DVE 160 are portable.- They are variable. The same turbine can be used for the fall of 5 m or 20 m. This will change only generator delivery and transmission.They can be equiped by the equable, asynchronous or synchronic generator.They can also directly drive pump for irrigation, mills etc.

- They are environmentally friendly. They can use only part flow and increase the flow by the original watercourse.Due to small openings in suction basket ( cca 10 as far as 30 mm) there is no danger of sucking the aquatic animals.
