①表現(xiàn)：矩形通風管道兩相對平面、兩端面不平行；折角不平直；對角線不相等；咬口不嚴。

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影響：會使通風管道連接受力不均勻，安裝后的通風管道不平直，法蘭盤墊片不嚴密，系統(tǒng)漏風，造成空調(diào)負荷損失，并且縮短使用壽命。

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：板下料放樣不準確；通風管道兩兩平行，相對面的板料長度和寬度不相等。

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：展開下料時，應(yīng)對板料嚴格角方，對每片板料的長度、寬度以及檢驗對角線，使它們的偏差控制在允許范圍內(nèi)；下料后的板料，應(yīng)將通風管道相對面的兩片板料重合檢驗尺寸準確性。

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.
