<p>Improvements in the regulation of fluid conditioning stations which comprise a plurality of pumping devices (2,3,4), at least one fluid storage reservoir (5,6), at least one pressure transducer and regulating means, the conditioning station providing a fluid at a certain pressure and flow for consumption, the pumping devices (2,3,4) starting and stopping such that the pressure in the fluid storage reservoir or reservoirs (5,6) is maintained between two limit values of pressure (the start pressure and the stop pressure), the improvements being characterized in that only one pumping device is started when the pressure in the storage reservoirs (5,6) reaches or exceeds the value of the start pressure and/or when the flow provided by the pumping devices (2,3,4) in operation is less than the consumption flow; and only one pumping device is stopped when the pressure in the storage reservoirs (5,6) reaches the value of the stop pressure and/or when the flow provided by the pumping devices (2,3,4) in operation is greater than the consumption flow. Operation is optimized. <IMAGE></p> |
