Operation of filter for liquids, especially liquid fuels, lubricants, cooling lubricants and washing liquids, comprises filter phase and reversible flow phase

摘要

The operation of a filter (10) for liquids comprises a filter phase and a reversible flow phase. Before, during and/or after the reversible flow phase the filter device is cleaned using at least one cleaning process deviating from a first reversible flow process, especially in the cleaning medium or in the flow characteristics of the reversible flow medium. An independent claim is also included for a system for carrying out the above process. Preferred Features: The duration, intensity and/or flow characteristics of the cleaning or reversible flow medium in the cleaning phase and of the reversible flow medium in the reversible flow phase are adjusted using a preferably programmable control unit or are self-adjusting.
