　　1、济南排烟罩支风管制作时，按设计尺寸，在主风管上切割支风管的边接口，与支风口上下板连接的开口尺寸为支风管内壁尺寸加大6mm。与支风管左右板连接处的开口尺寸为支风管外壁尺寸，并在顺风方向设置45°导流角，导流角的长度不得小于支风管宽度的1/2。

　　1. When making the air duct, according to the design size, the side interface of the air duct is cut on the main air pipe, and the opening dimension connected with the upper and lower plates of the air support is a supporting air pipe, and the inner wall dimension is increased by 6mm. The opening dimension at the connection of the left and the right plates of the branch pipe is the outer wall dimension of the branch duct, and the 45 DEG diversion angle is arranged in the downwind direction, and the length of the diversion angle shall not be less than 1/2 of the width of the draft pipe.

　　2、制作矩形弯管时，济南通风管道工程一般采用由若干块小板拼成折线的方法制成内外同心弧型弯管，与直风管接连口制成错位连接形式。

　　2, make the rectangular pipe, commonly used by some methods into small plates made of concentric arc and line pipe and straight duct mouth made successive dislocation connection form.

　　3、制作三通(蝴蝶三通)时，根据图纸尺寸，划出两平面板尺寸线，并切割下料。

　　3,. When making the three pass (Butterfly three pass), draw the two flat panel size according to the drawing size, and cut the material.

　　5、矩形风管的变径管，有单面偏心和双面偏心两种，制作变径管单面变径的夹角宜小于30°，双面变径的夹角宜小于60°。

　　5, the rectangular air duct's reducing tube has two sides, one side eccentric and 60 sided eccentric, and the angle of the reducing diameter of the one-way reducing pipe is less than 30 degrees, and the angle between the two sides of the reducing pipe is less than 10 degrees.

　　6、变经风管制作与直风管制作方法相同，其中一面或三面风管管板是斜面。变径风管的长度不得小于大头长边减去小头长边之差。

　　6. The manufacture of the warp air duct is the same as that of the direct air duct. One or three sides of the air duct plate are inclined. The length of the variable air pipe shall not be smaller than the long side of the big head and the difference between the long side and the small end.
