Construction requirements for air conditioning systems in clean workshops?
All air ducts, accessories and equipment in the clean workshop must be wiped clean before installation to ensure that the air ducts, accessories and equipment are clean and intact; Check for air leakage, the high-efficiency filter has been decorated in the clean workshop, the system has undergone trial operation, and the room has been thoroughly cleaned before installation; the equipment connected to the enclosure structure can be installed at the same time as the enclosure structure, but the sealing work must be done well; The inner surface of the pipe should be flat and smooth, there should be no horizontal joints, and vertical joints should be minimized. Cold-rolled steel plates and galvanized sheet air pipes with poor refrigeration should be painted with high-quality primer and topcoat after decontamination and rust removal. Two; after the air duct parts are made, they should be cleaned with non-corrosive lotion, wiped with a fabric that is not easy to lint, and then sealed for installation. The air duct should be installed immediately after unsealing; the port should be re-sealed during installation, and the system should be installed. The gasket should be made of materials that do not produce dust and have good elasticity, with a thickness of 4mm-6mm; the inner side of the gasket should be flush with the inner wall of the air duct after the flange is pressed; the equipment should be unpacked in a clean room, and should be Wipe the inner and outer surfaces clean, and install it immediately. After installation, the supply, return, exhaust and equipment operation are sealed immediately, and only opened when it is put into operation.
Sealing measures must be implemented in all installation links. The gaps and holes at the flanging of the metal air duct should be coated with sealant or adhesive tape, and the distance between flange screw holes and rivet holes should not be greater than 100mm ; The gasket should minimize the number of joints, the joints should be stepped or grooved, and coated with sealant, and all the screws of the flange should be pressed evenly; the sealing between the high-efficiency filter and the frame can be made of gaskets, self-adhesive Or liquid tank sealing, when using gasket sealing, its thickness should not exceed 8mm, and the compression rate is 25%-30% to ensure the sealing effect; the seam between the purification equipment and the maintenance structure and the bottom surface or bottom edge close to the ground The safety cabinet should be sealed along the ground edge to maintain positive indoor pressure and prevent mold growth at the bottom of the safety cabinet. In order to ensure that the air conditioner is airtight and does not leak air. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean workshops and clean rooms.
Meticulous work is an important part of the entire production and installation process. The transportation and storage of high-efficiency filters and other purification equipment should be placed in the direction of the factory signs; Handle with care to prevent violent vibration and collision; the equipment must be carefully inspected before installation, including appearance, size and assembly quality, etc. The high-efficiency filter of the high-level system also needs to be leaked on site. For the same air outlet, install multiple The resistance of the filter should be adjusted, and the difference between the resistance of each filter and the average resistance of each filter should not be less than 5%; the ground on which the equipment is installed should be flat and level, and a vibration isolation layer should be placed between the purification equipment with a fan and the ground. , For the construction and installation of the system, you should always pay attention to whether there is leakage and pollution; record the problems and measures taken during the construction and installation process, and establish a construction and installation file.
