Beijing Yifengda Machinery Co., Ltd.

Beijing Yifengda Machinery Co., Ltd. interprets the relevant knowledge and details of the five-line manufacturers of wsvMS Lianyungang duct production for you. 1. Process requirements 1. Before dismantling the air duct, the drawings should be taken from the construction site to stop checking, and check whether the dismantling can be stopped according to the envisaged elevation and position; The air duct connected to the entrance and exit of the air duct has separate support, and it is not allowed to add the stack weight of the duct to the components of the air duct; when installing and removing the air duct, you should pay attention to the degree of the air duct and take the foundation of the air duct The connection of the air duct taken out of the separation surface should be adjusted so that it matches naturally, and no forced connection is allowed. 2. Use infrared positioning and pay-off to ensure the spacing and curve of the air pipe, and find the installation position of the boom according to the center line of the air pipe, and stop the installation of the hanger; 3. After the dimensions and angles of the various departments of the air duct system are confirmed to be correct, the starting group is installed and disassembled. The joint policy of the air duct should be flat and not twisted, and the nuts of the connecting flange should be on the same side; 4. The gasket between the air duct and the flange of the air duct adopts a heat-resistant rubber plate with a thickness of 3 mm or more. The gasket should not protrude into the pipe and should not protrude from the flange. The gasket should not contain Lianyun and other harmful Ingredients, and should be resistant to oil, moisture, acid and alkali corrosion; 5. When installing the air duct, it is necessary to connect the center line of the air duct, and use a ruler to measure the degree after installing a section of air duct. vice. In recent years, the floor heating market has developed rapidly. The main heating methods are: radiator heating, floor heating, and electric film heating. 6. When the air pipe is passing through the fire-proof and explosion-proof wall or floor slab that needs to be blocked, a pre-buried pipe or protective sleeve should be installed, and the thickness of the steel plate is 2mm. Between the air duct and the protective sleeve, it should be sealed with flexible materials that are non-combustible and harmless to the human body; 7. For the installation and disassembly of various types of air duct components and operating mechanisms, first check whether the shape of the valve and the operating mechanism are intact, check the sensitivity of the operation, and confirm that all aspects of the valve are stopped. There should be at least 350mm of clear space on the side of the valve operating mechanism for operation and maintenance; the fire valves on both sides of the partition wall of the fire protection partition should not be more than 200mm outside the partition wall; Insulation function Galvanized thin steel plate duct: great thermal conductivity (WmK), no insulation function, additional insulation layer and protective layer are required. Insulation thickness in the duct processing area is not easy to guarantee or no insulation, cold bridge phenomenon will occur, the uniformity of coverage of the insulation layer of the duct wall surface is sometimes difficult to guarantee due to insufficient clearance. Inorganic glass fiber reinforced plastic air duct: large thermal conductivity (.WmK), no insulation function, additional insulation layer and protective layer are required, and the insulation layer has the same characteristics as galvanized thin steel duct. Composite fiberglass duct: small thermal conductivity (.WmK at uniform temperature, .WmK at time), especially the appearance of composite aluminum foil cloth with high heat reflection ability. Because the air duct wall is the insulation layer, the pipe adopts the tenon joint, the T-shaped inner frame butt joint and the iron skin plug (or outer flange connection), so that the entire air duct is insulated evenly, no cold bridge phenomenon occurs, and it has excellent Thermal insulation function. 8. The collection and hanger of the fire smoke exhaust duct must be set separately, and the collection, hanger, pipe muffler, muffler elbow and fire valve must be set separately; 9. After the installation of the air duct is completed, the tightness inspection should be stopped according to the system pressure level. Composite fiberglass duct: small thermal conductivity (.WmK at average temperature, .WmK at time), especially the surface composite aluminum foil cloth has a high heat reflection ability. 2. Key points of volume control 1. It is strictly forbidden to pass pure objects or other pipelines in the air pipe, and do cleaning and sheltering work; 2. The lower edge of the hanger and the outer edge of the contact net charged body (including load-bearing cables, lower feeders, etc.) must be connected at a quiet distance greater than 230mm, and should be strictly implemented in accordance with the limits; 3. The connecting bolts should be galvanized bolts, and must be equipped with corresponding flat washers, spring washers and nuts; 4. The working temperature of the air duct flange gasket is not less than 70; the working temperature of the exhaust duct flange gasket is not less than 250; 5. The water lianyun for the installation of the air duct should not be more than 3mm per meter, and the total deviation should not be more than 20mm; the vertical deviation of the vertical curvature of the vertical curve should not exceed 2mm per meter, and the total deviation should not be more than 20mm; 6. The air duct is passing through the wall or floor slab. No interface should be set. When the air duct is installed along the wall or floor slab, the distance between the wall and floor slab should be greater than 150mm; 7. The electric execution mechanism of the air valve must be reliably fixed, and it is strictly prohibited to be placed on the air pipe at will; 8. The manual sealed valve is installed and removed. The purpose of the arrow marked on the valve must be consistent with the purpose of the shock wave mark. If gas branch pipes are installed in the interior of commercial users, they shall be buried in the floor of the floor or sealed in the pipe trench filled with dry sand. 9. The configuration of the site air duct interface must not reduce its effective cross-section; 10. Non-combustible insulation pads should be installed on the cut to length line machine air-conditioning duct retractor hanger to avoid the occurrence of cold bridges. The insulation pad should be anchored on the crossarm when the retractor hanger is made 11. For the detection of the system's air duct, it is advisable to adopt the method of segmented detection and summary analysis. On the basis of strict installation and quantity management, the detection of system air ducts is mainly based on main pipes and main pipes. When the leak detection method is adopted to check the tightness of the system, the air duct of the low-pressure system shall pass every 10m, the light leakage point shall not be greater than 2, and the average joint of 100m shall not exceed 16; The light leakage point is not more than 1 and the 100m joint is not more than 8 evenly. The duct air nozzle depends on how many air nozzles are opened in the manufacturers workshop. Generally, it is better. If you want to open more, it is also possible. However, the air nozzle should be smaller. For example, such a specification may be opened. I will open more. After that, the wind is smaller, but Fang said that it can be turned off without use, which is also ok, but it is generally opened as little as possible when it is not necessary. 3. Waste product asylum measures 1. The air duct should be handled and disassembled gently, and should not be dragged in the air, and it should be prevented from bumping and tripping; the zinc plating of the flange should not be damaged. 2. In the process of lifting and dismantling the air duct, the unconnected ends of both ends must be sealed with plastic film. Before the air duct of the air duct is removed, the plastic film should also be used. 3. Regarding press brake manufacturers the air duct of the house through the mechanical tools, the plastic wall must be sheltered within 500mm from the wall to prevent the air duct from being polluted by the ash material of the civil construction unit; 4. It is strictly forbidden to pile pure objects on the installed air pipe or the station is under construction. Moreover, all home appliance solutions have begun to arouse, and after-sales integration has now become a trend. The connection method of the air pipe is flange type, which accepts angle steel flanges, also accepts integral flanges, and whether it can contain air pipe parts (elbows, reducers, tees). For example, use angle steel flange to add% according to the air duct expansion area (the rest of the steel plate can be spliced). Commonly used specifications on the market are meters.
