Qingdao white iron sheet air ductThe installation method:

1. Manufacturing method and drawings of support and hanger manufacturing device

According to the specifications, different specifications of Qingdao white iron wind pipe using different sizes of hangers. The length of the boom shall be cut according to the ratio of Qingdao white iron sheet duct to the height of the device and the height of the floor beam or steel frame. The boom hanging code is processed by angle steel. The thread at the end of the boom conforms to the height adjustment requirements of the air duct. The top of the boom is welded and fixed by angle steel code. The boom is brushed with antirust paint and finish paint twice. After the boom is manufactured, it can be installed in the direction of the air duct, and the spacing meets the planning and specification requirements.

2. Lifting of Qingdao white iron sheet wind pipe

The installation of Qingdao white iron sheet wind pipeline shall meet the requirements of planning drawings and national specifications. Clean the assembly parts before installing the air duct. Then, according to the distribution of each system on the drawing and the number of ducts manufactured, place and assemble the iron ducts. Check the air duct alignment and axis direction before hoisting.

Manual hoists for lifting operations can be used with lifting teams. During the lifting process, pay attention to the balanced lifting of the tin tube to prevent the side from sliding or tipping over. The air duct is fixed on the support hanger with an angle steel cross arm. When installing Qingdao white iron sheet wind pipeline, the main pipe should be as close to the beam bottom as possible, and the branch pipe should be as high as possible. Interspersed operations, cooperate with hydropower construction, and pay attention to safety together. After the installation is completed, check whether the height of the air duct device meets the planning requirements, whether the levelness and verticality of the air duct meet the specification requirements, whether the bracket is inclined, and whether the bracket spacing meets the requirements.

　　Qingdao white iron sheet air ductHow to make the road?

1. Marking should be carried out according to the different sizes, shapes and specifications of the air duct, and the air duct with the same section should be completely carried out to prevent marking errors and feeding errors.

2. The plate cutting is carried out separately according to the different marking stages, and the cutting needs to be re-checked to avoid errors. Cut into a straight line with mechanical scissors and hand scissors.

3. During shearing, it is strictly forbidden to reach into the gap of the mechanical pressure plate. The tool holder shall not place tools and other articles. When adjusting the plate, the feet shall not be placed on the pedal. Use fixed vibration to shear the hand to stabilize the steel plate. The hand shall not be less than 5cm from the knife edge, and the force shall be uniform and appropriate.

4. After the material plate is rolled, it is necessary to use a chamfering machine or scissors for chamfering.

5. Qingdao white iron sheet air duct is made of metal thin steel plate, which is connected by different methods such as bite, rivet and welding.

6. The bite width and retention force are determined according to the thickness of the steel plate.

7. When welding, the weld seam should be uniform, and there should be no cracks and slag inclusions. When rivets are connected, the center of the rivet is perpendicular to the plate surface, and the rivet head compresses the material to make the plate seams arranged neatly and evenly. Riveting between the plate and the plate, the middle generally does not need padding, according to the design requirements.

8. When biting the plate, the distance between the finger and the roller shell is not less than 50mm, and the hand must not be placed on the track of the plate biting machine to stabilize the plate.

9. After the bite of the plate, the folding line is drawn on the folding machine, placed at the center line of the lower die, and operated so that the center line of the mechanical blade coincides with the center line of the lower die and is folded into the required angle.

10. Folding should be with the folding machine to maintain a certain distance, so as not to be turned over the steel plate or accessories.

11. When making a round air duct, the two ends of the bite should be shot into an arc and placed on the winding machine. AccordingQingdao white iron sheet air ductDiameter specifications are properly adjusted. The distance between the upper and lower rollers is large, and the hand cannot directly push the steel plate during operation.

12. Use a plywood machine or manual plywood after folding or rolling round. Use even force during operation, not too heavy. Single, double bite, no bursting and half bite phenomenon.
