3.3.2 风机安装定位不合理，导致风机无操作、检修空间。
风机安装无检修空间
四 片式消声器安装
4.1工艺流程
4.2操作要点 4.2.1片式消声器安装每个纵向段的消声片应相互平行，其组件 竖直方向接口必须对齐，垂直度允许偏差为1/1000；消声器前端外缘 应处于与气流方向垂直的同一平面内且与中间连接牢固。
片式消声器安装
4.2.2片式消声器的消声片的顶部、底部及消声片临近侧壁方向 应与结构壁面结合牢固，在额定风量下不得出现松动或振颤现象，如与结构墙面的缝隙大于30㎝以上时必须采取封堵措施。
片式消声器安装
4.3注意事项
4.3.1片式消声器进场未进行覆盖保护，导致消声片污染、受潮、 锈蚀、变形，影响消声器消声效果，无法安装，存在安全隐患。
