Valve exploiting the principle of a side channel turbine

Popis výsledku v původním jazyce

The presented article deals with a side channel turbine, which can be used as a suitable substitute for a pressure reducing valve. Reducing valves are a source of hydraulic losses. The aim is to replace them by a side channel turbine. With that in mind, hydraulic losses can be replaced by a production of electrical energy at comparable characteristics of the valve and the turbine. The basis for the design is the loss characteristics of the valve. Thereby creating a kind of turbine valve with speed-controlled flow in dependence of runner revolution. The side channel turbine falls into the category of reaction turbines. They are intended for small discharges and medium heads. The working area is within the specific speed ns = 2 - 30 min-1. The turbine can only process a part of the head. The main disadvantage is low efficiency, which is usually within the range of 20 to 50%. These machines find their use due to the fact that reaching specific speed ns < 35 min-1 with Francis’ turbines at high efficiency
