Method for pumping and suction of fluid and pressure increasing, pressure reducing, heating and cooling of gas in e.g. biogas plant, involves fastening disks on axis at different distances, and calculating different conditions of medium

摘要

The method involves fastening disks on a central axis at different distances, and calculating different conditions of medium (3) e.g. liquid, saturated steam or gaseous medium, where projection elements are arranged on an outer side of the disks. The distance between the disks is changed based on condition of the medium during the process. Force transmission to a motor and/or generator is carried out over coupling elements i.e. magnetic couplings. Flow velocity of the medium is increased by an air gap between the disks and a casing by using Bernoulli effect.
