根据茂名石油工业公司炼油厂同类装置的开工经验,若按原设计施工方案进行空冷器的安装,则会引起主管架共振和噪声的严重超标.为此,在南京炼油厂加氢裂化空冷安装时,采取了三项有效的减振降噪声的措施.这三项措施是:主管架与风机架连接处采用柔性连接;连接处进行机械加工,以增加接触面积;框架进行收缩整形.经加氢裂化装 According to Maoming Oil Refinery Plant start-up experience of similar devices, according to the original design and construction program for the installation of air-cooled, it will cause the main rack resonance and noise seriously exceeded.To this end, Nanjing refinery hydrocracking air-cooled installation , Three effective measures have been taken to reduce noise and reduce noise: flexible connection at the connection between the main frame and the wind frame, mechanical processing at the connection to increase the contact area, and the frame to shrink and shape.
