摘要： A rapping hammer system adapted for periodically rapping and cleaning tubes (11) of a heat exchanger unit (10) to remove undesired deposits from outside the tubes. A plurality of rapping hammers (14) are each pivotably attached to a radial arm (18) extending outwardly from and spaced apart along a rotatable shaft (20). A spring device (22) is attached to each radial arm (18) and arranged to contact the rapping hammer with sufficient force so as to substantially restrain repeated striking movements of the rapping hammer against an impact stem (13) of the heat exchange unit following an initial impact of the hammer (14). A method is also disclosed for operating the rapping hammer system for periodically rapping and cleaning the outside surface of heat exchanger tubes such as boiler tubes of accumulated ash and soot deposits.
摘要翻译：该系统适于周期性地敲击和清洁热交换器单元的管道以从管外部去除不需要的沉积物。一些敲击锤各自可旋转地连接到沿着可旋转轴向外延伸并且沿着可旋转轴间隔开的径向臂。弹簧装置连接到每个径向臂上并布置成以足够的力接触敲击锤，以便在敲击锤的初始冲击之后抑制敲击锤重复撞击热交换单元的撞击杆的冲击运动。还公开了一种用于操作敲击锤系统的方法，用于周期性地敲击和清洁热交换器管的外表面，例如堆积的灰分和烟灰沉积物的锅炉管。
