METHOD AND DEVICE FOR CONTROLLING THE PRESSURE AND / OR FLOW RATE OF FLUID

摘要

The invention relates to a method for controlling the pressure and / or the flow rate of a fluid. For this method, flow energy is withdrawn from a fluid flowing through a pipeline (15). This energy is converted at least partially into electrical energy and used for the electrical control (65) of the flow rate and / or the pressure of a fluid. The device for controlling the flow rate and / or pressure of a fluid in a pipeline (20) has at least one electric generator (35), which is developed for the withdrawal of flow energy from a flowing fluid and for converting this energy at least partially into electrical energy. The device has means (65) for controlling the flow rate and / or pressure of a fluid in a pipeline (20) with an electric driving mechanism supplied by the generator (35).
