Device for increasing the pressure of materials which can be conveyed in pipelines, method for operating this device, and control construction for carrying out the method

摘要

The invention relates to a device which is based on volume displacement and is used for increasing the pressure of materials which can be conveyed in pipelines, a method for operating this device, and a control construction for carrying out this method. This system comprises at least three tube sections which are arranged in series, represent delivery chambers with elastic walls, and are compressed from the outside by means of a pressurised medium, offset in time relative to one another, and are thereafter released again for expansion. <IMAGE>
