①表现：矩形通风管道两相对平面、两端面不平行；折角不平直；对角线不相等；咬口不严。

① Performance: two relative planes and two end planes of rectangular ventilation duct are not parallel; The angle is not straight; The diagonals are not equal; The bite is not tight.

②影响：会使通风管道连接受力不均匀，安装后的通风管道不平直，法兰盘垫片不严密，系统漏风，造成空调负荷损失，并且缩短使用寿命。

② Influence: it will make the ventilation pipe connection stress uneven, after the installation of the ventilation pipe is not straight, flange gasket is not tight, system air leakage, resulting in air conditioning load loss, and shorten the service life.

③原因：板下料放样不准确；通风管道两两平行，相对面的板料长度和宽度不相等。

③ Causes: inaccurate setting out of plate cutting; The ventilation pipes are parallel, and the sheet length and width of the opposite side are not equal.

④措施：展开下料时，应对板料严格角方，对每片板料的长度、宽度以及检验对角线，使它们的偏差控制在允许范围内；下料后的板料，应将通风管道相对面的两片板料重合检验尺寸准确性。

④ Measures: when unfolding and blanking, the angle of sheet metal should be strictly square, and the length, width and diagonal of each sheet metal should be inspected to control their deviation within the allowable range; After blanking, two pieces of sheet metal on the opposite side of the ventilation pipe shall be overlapped to check the dimensional accuracy.
