Clean room ventilation and air conditioning system installation
The production of clean room air ducts should have approved drawings, reviewed large-scale drawings, system drawings, and a written technical quality and safety disclosure report by the constructor; Different methods such as rivet connection; when connecting rivets, the center line of the rivets must be perpendicular to the board surface, the rivet head should press the board tightly, so that the board seams are tightly closed and the rivets are arranged neatly and evenly; Take it into an arc shape and place it on the rolling machine to roll a circle, adjust the distance between the upper and lower rolls according to the diameter of the air duct, and do not directly push the steel plate by hand during operation; the steel plate after folding or rolling is seamed with a seaming machine or by hand. , The force is uniform during production, it is not easy to be too heavy, the single and double mouths are indeed engaged, and there is no bursting and half-biting phenomenon; the interface that cannot be connected to the air duct should be machined, the size should be correct, the shape should be regular, and the interface should be tight. The four corners of the flangeless rectangular air duct interface should be fixed. The flangeless connection of the air duct can be socketed and inserted into the air duct. When the riveted flange waistband is punched, the face of the personnel outside the duct should avoid punching; If the side length of the pipe is greater than or equal to 630mm and the side length of the thermal insulation duct is greater than or equal to 800mm, reinforcement measures should be taken when the length of the pipe section is more than 1200mm. Method reinforcement; when the length of the pipe section of the medium and high pressure air duct is greater than 1200mm, it should be reinforced in the form of a reinforcement frame; the single bite seam of the high pressure air duct should have reinforcement measures; when the thickness of the plate of the air duct is greater than or equal to 2mm, the scope of the reinforcement measures can be appropriately relaxed.
Check the technical quality before riveting the air duct and the flange. After passing the test, put the flange on the air duct, leave about 10mm flanging at the end of the pipe, and the folding line of the pipe should be perpendicular to the plane of the flange, and then use Hydraulic rivet pliers or manual clamping pliers use rivets to fasten the air duct and the flange, and leave the surrounding flanging; the flanging should be flat and should not cover the screw holes, the four corners should be leveled, and there should be no gaps to avoid air leakage ; The connection between the air duct and the small parts and the branches of the three-way and four-way should be tight, and the gap should be blocked by soldering or sealant to avoid air leakage; the appearance quality of the air duct should be straight and straight, the arc should be uniform, and the two ends should be parallel. , no warping angle, the surface unevenness is not more than 6mm, the air duct and the flange are firmly connected, the flanging is flat, the width is not more than 6mm, and it is close to the flange; the flange hole distance of the air duct should meet the design requirements and construction specifications, and the welding It should be firm, and there are no screw holes at the welding seam, and the screw holes are interchangeable; the surface of the galvanized steel sheet should be kept smooth and clean, and it should be placed on a spacious and dry moisture-proof pad frame and stacked neatly; the finished air duct should be stacked on a flat, No stagnant water, spacious site, not mixed with other materials and equipment, should be numbered according to the system when stacking, neat, reasonable and easy to ship. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, renovation and other supporting services for clean rooms and clean rooms.
The form, specification, position, spacing and fixation of the support, suspension and bracket must meet the design requirements and construction specifications. It is strictly prohibited to set it at the air outlet, valve and inspection door. The stainless steel and aluminum plate air ducts must be made of carbon steel. Carry out anti-corrosion insulation and isolation treatment; when the inclined flap valve is installed vertically, the valve plate must be pulled upward; when installed horizontally, the valve plate should be inserted in the direction of the airflow, and the valve plate should not be pulled downward; the air cap must be installed firmly, and the air duct and roof Water leakage is strictly prohibited at the junction; the air duct connection must be tight and leak-proof, the flange gasket and the joint method must meet the design requirements and construction specifications; the material used for the flexible short pipe of the cleaning system must be dust-free, airtight, smooth inner wall, flexible short The connection between the duct and the air duct and equipment must be tight and leak-proof; the inner wall of the air duct and static pressure box of the clean system must be clean after installation, free of dust, oil, rust and debris; the flange connection of the air duct is parallel, tight, and bolted. Tighten, the exposed length of the bolts is appropriate and consistent, and the flange nuts of the same pipe section are on the same side; the flexible short pipe is properly tight, and the length meets the design requirements and construction specifications, and there is no cracking and distortion.
