来源:http://www.jntfgd.com 日期:2021-11-08 发布人:jntfgd

1、按照重庆共板法兰风管的线找出吊杆敷设位置,单吊杆在风管的线上,双吊杆可以按托盘的螺孔间距或风管的线对称安装。
1. Find out the suspender laying position according to the center line of Chongqing common plate flange air duct. The single suspender is on the center line of the air duct, and the double suspenders can be installed symmetrically according to the screw hole spacing of the tray or the center line of the air duct.
2、吊杆根据吊件形式,可以焊在吊件上,也可挂在吊件上,焊接后应涂防锈漆。
2. The suspender can be welded on the suspender or hung on the suspender according to the form of the suspender. After welding, it shall be coated with antirust paint.
当风管较长需要安装一排支架时,可先把两端安好,然后以两端的支架为基准,用拉线法找出中间支架的标高进行安装。
When the air duct is long and a row of supports need to be installed, the two ends can be installed first, and then the elevation of the middle support can be found out by the pull wire method based on the supports at both ends.
3、立管管卡安装时,应先把上面的一个管件固定好,再用线锤在处吊线,下面的管卡即可按线进行固定。
3. When installing the riser pipe clamp, first fix the upper pipe fitting, then hang the line at the center with a wire hammer, and the lower pipe clamp can be fixed according to the line.

4、风管支吊架间距如无设计要求时,对不保温风管应符合下表的要求。对于保温风管的支、吊架间距无设计要求时,按下表间距要求值乘以0.85。重庆螺旋风管加工的成品的支、吊架间距可以适当增加。
4. If there are no design requirements for the spacing of air duct supports and hangers, the uninsulated air duct shall meet the requirements in the following table. If there are no design requirements for the spacing between supports and hangers of insulated air duct, multiply the spacing requirements in the following table by 0.85. The spacing between supports and hangers of finished products processed by Chongqing spiral air duct can be appropriately increased.
、支吊架不得安装在风口、阀门检查孔处,以免妨碍操作。吊架不得直接吊在法兰上。
Supports and hangers shall not be installed at the air outlet and valve inspection hole to avoid hindering the operation. The hanger shall not be directly hung on the flange.
2、保温风管不能直接与支吊架接触,应垫上坚固的隔热材料,其厚度与保温风管厚度相同,防止产生“冷桥”。
2. The thermal insulation air duct shall not be in direct contact with the supports and hangers, and shall be padded with solid thermal insulation materials with the same thickness as the thermal insulation air duct to prevent "cold bridge".
3、聚氯吞烯风管也与钢板风管一样采用支、吊托架,但一般以吊架为主,支架间距按下表的要求制作安装,
3. Like steel plate air duct, polychlorotiene air duct also adopts support and hanging bracket, but generally it is mainly hanger, and the spacing of support is manufactured and installed according to the requirements in the table below,
法兰连接:
Flange connection:
为保证法兰接口严密性,法兰之间应有垫料。在无特殊要求的情况下,法兰垫料按下表选用。
In order to ensure the tightness of flange interface, there shall be padding between flanges. In case of no special requirements, flange gasket shall be selected according to the following table.

抱箍式连接:主要用于钢板圆风管和螺旋风管连接,先把每一管段的两端轧出鼓筋,并使其一端缩为小口。安装时按气流方向把小口插入大口,外面用钢制抱箍将两端的鼓箍抱紧连接,后用螺栓穿在耳环中间固定拧紧。
Hoop type connection: it is mainly used for the connection of steel plate round air duct and spiral air duct. Firstly, roll out the bulge reinforcement at both ends of each pipe section and shrink one end into a small mouth. During installation, insert the small opening into the large opening according to the air flow direction, tightly connect the drum hoops at both ends with steel hoops, and then screw them through the middle of the earrings with bolts.
插接式连接:主要用于矩形或圆形风管连接。先制作连接管,然后插入两侧风管,再用拉铆钉将其紧密固定。
Plug in connection: mainly used for rectangular or circular air duct connection. First make the connecting pipe, then insert the air ducts on both sides, and then fix it tightly with pull rivets.
插条式连接:主要用于重庆矩形风管加工成品的连接。将不同形式的插条插入风管两端,然后压实。
Plug in connection: it is mainly used for the connection of finished rectangular air duct in Chongqing. Insert different forms of inserts into both ends of the duct and compact.
软管式连接:主要用于风管与部件(如散热器、静压箱侧送风口等)的相连。安装时软管两端套在连接的管外,然后用特别软的卡箍把软管箍紧。
Hose connection: it is mainly used for the connection between air duct and components (such as radiator, plenum side air supply outlet, etc.). During installation, both ends of the hose shall be sleeved outside the connected pipe, and then the hose shall be clamped tightly with a particularly soft clamp.
