Clean room purification equipment supply and installation

The floor of the clean room installation equipment should be flat and the environment should be clean. Before installing the equipment, the dust and oil on the inner and outer surfaces should be wiped off. The installation can only be carried out after passing the inspection. The vibration isolation layer should be padded; the equipment with interlocking device should be restored to normal interlocking after installation and debugging. The biological safety cabinet should be inspected after each installation and movement. When the design is not specified, all joints must be sealed. After the cabinet seams are sealed, the operation port negative pressure test, the operation area and the operation port airflow should be carried out. Speed u200bu200btest, pressure leakage test, leakage test of high efficiency air filter, water leakage test of washing basin and grounding line resistance test of grounding device; the installation of biological safety exhaust filter device must strictly follow the design regulations; The rotating shaft of the pressure valve, the valve body and the movable valve plate should be horizontal, and the allowable deviation is ±2mm. The installation position of the residual pressure valve should be on the leeward side of the indoor air flow, and should not be within the height range of the working surface; the installation of the transfer window should be firm , straight, and the connection with the wall should be sealed.

In the installation of the clean laminar flow hood, an independent boom should be installed, and there should be fixed measures to prevent shaking; the allowable deviation of the horizontality of the laminar flow hood installation is 1‰, and the allowable deviation of the height is ±1mm; when installed on the ceiling, There should be sealing and vibration isolation measures between its surrounding and the top plate. The fan filter unit should be visually inspected at the site of the clean room, and there should be no deformation, corrosion, paint film peeling, damage to the splicing plate, etc., and a temporary medium-efficiency filter must be installed at the air inlet when the system is in trial operation. Protection; the high-efficiency filter of the fan filter unit should be checked for leaks according to the detailed filter installation regulations before installation, and the installation must be carried out after passing the test, and the direction must be correct; the installed FFU fan filter unit or unit should be kept flat as a whole and connected to the ceiling Good, easy to maintain, the connection between the fan box and the filter, the filter unit and the ceiling frame should have reliable sealing measures. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean rooms and clean rooms. It has qualifications in decoration, electromechanical installation, and purification industries, and has many successful cases.

The installation of the clean room siding is carried out according to the requirements of laying the ground line of defense. The corners should be connected vertically to prevent the siding from being inclined and twisted due to accumulated errors. First replace the bottom manger, and connect the sealing strip to the bottom manger. The lines are well connected, and the seams between the manger and the wall panels are staggered. The installation sequence of the wall panels starts from the corners. Sealing strips should be used at the grooves on both sides. When installed to a certain length, a section of the top manger should be pre-deducted to ensure that the wall panels are in good condition. Overall strength; the seal of the siding should be located at the opening or corner. After the clean room siding is installed, the corner and the top manger should be pre-installed and made parallel and vertical, and the joints and the joints of the wall should be staggered. ; After assembly, the splicing joints between the wall panels and between the wall panels and the top panel should be flat and tight, the allowable deviation of the verticality of the wall panels is 2‰, and the allowable deviation of the geometric dimensions and design requirements of each single room after assembly is 2‰; The structure of the ceiling is also determined according to the air flow form. For the ceiling of the vertical parallel airflow clean room, a high-efficiency filter needs to be installed, and the ceiling of the horizontal parallel airflow clean clean room modular does not need to install a high-efficiency filter, but a sealed structure is used. The ceiling should be provided with a local air supply port; the inner side of the ceiling frame should be affixed with sealing strips, and the ceiling blocks should be embedded in the frame and fixed. The ceiling with high-efficiency filters should be cleaned indoors and in the ventilation system to meet the standard requirements. After the load, it can be carried out; the ceiling should be kept straight after bearing the load, and all the beading should be close to each other.
