Abstract
An apparatus (10) for the vibration control of a rising pipe (3) of a vertical pump is presented which riser pump is excited to vibrations in operation and which has a longitudinal direction. The apparatus (10) is outwardly positionable at the rising pipe and includes a vibration element (7.1, 7.2), one or more spring elements (8.1-8.4) and a guide, wherein the vibration element has an opening to surround the rising pipe (3) and is movably and elastically held by the spring element or elements (8.1-8.4), and wherein the vibration element (7.1, 7.2) is guided by guide such that the movements of the vibration element in operation are restricted to movements in a plane perpendicular to the longitudinal direction of the rising pipe.
Claims14
An apparatus for the vibration control of a rising pipe (3) of a vertical pump which rising pipe is excited to vibrations in operation and which has a longitudinal direction, characterised in that the apparatus (10) can be positioned outwardly at the rising pipe;
- in that the apparatus includes a vibration element (7, 7.1, 7.2), one or more spring elements (8, 8.1-8.4) and a guide (9);
- in that the vibration element has an opening to surround the rising pipe and is held movably and elastically by the spring element or elements;
- and in that the vibration element (7, 7.1, 7.2) is guided by the guide (9) such that the movements of the vibration element in operation are restricted to movements in a plane perpendicular to the longitudinal direction of the rising pipe.
A method for the vibration control of a rising pipe (3) of a vertical pump which rising pipe is excited to vibrations in operation and which has a longitudinal direction, characterised in that a vibration element (7, 7.1, 7.2) is provided for the vibration control which surrounds the rising pipe (3) and which is movably and elastically held with respect thereto by one or more spring elements (8, 8.1-8.4);
- in that the vibration element (7, 7.1, 7.2) is guided by a guide (9) which restricts the movements of the vibration element to movements in a plane perpendicular to the longitudinal direction of the rising pipe;
- and in that the vibration element (7, 7.1, 7.2) and the spring element or elements (8, 8.1-8.4) and the guide (9) are outwardly arranged at the rising pipe (3).
