Apparatus and method for the vibration control of a rising pipe of a vertical pump

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.

1 . 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.
