Installation of air conditioning and refrigeration system in clean pharmaceutical cleanroom
The specifications, models, performance and technical parameters of various pipe fittings and valves of the refrigeration system must meet the design requirements. The inner and outer surfaces of the seamless steel pipe should be free of obvious corrosion, cracks, peeling and uneven defects; It should be smooth and free of defects such as scarring, spalling, cracks or air bubbles; the material, specification and bearing rate of the equipment's anchor bolts and flat and inclined pad irons and unit area should meet the design and equipment installation requirements; during the installation of refrigeration equipment, except for In addition to preparing various standard fasteners and gaskets, materials such as lubricating oil, refrigerant and cleaning agent should also be prepared; the cleaning of parts and components is an important process in equipment installation. In order to ensure the quality of the installation project, the cleaning should be selected correctly agent.
In the installation of the piston refrigeration unit, the vertical and horizontal center lines of the equipment foundation should be ejected according to the positioning axis of the building according to the construction drawings, and the equipment should be hoisted to the equipment foundation with a forklift and a herringbone mast. The direction of the mouth should meet the design requirements, and the levelness of the equipment should be adjusted to the level close to the requirements; the equipment should be initially leveled with flat or inclined horns, and the placement position and quantity of the horns should meet the equipment installation requirements; The plumb line method is used to measure the machined surface of the cylinder, the base or the machined surface parallel to the base, and the equipment is precisely leveled so that the allowable deviation of the vertical and horizontal horizontality of the fuselage is 1/1000, and it should meet the requirements of the equipment technical documents; For the refrigeration compressor installed as a whole, usually only the outer surface is cleaned, and the internal parts are not disassembled and cleaned. However, if it exceeds the ex-factory shelf life of the equipment or has obvious defects, it should be cleaned; when the equipment is disassembled and cleaned, the original quality of the equipment should be measured. Assemble data and keep records and archives. Unqualified parts should be replaced. The gaps that do not meet the requirements of equipment technical documents should be adjusted and recorded. After cleaning the oil pipe, use compressed air to test it to verify its cleanliness. and unblocked, and use plastic cloth to tie and seal the end of the pipe, and let the dirt enter; during the disassembly and cleaning process of the installed equipment, do not use too much force, use soft material when hammering, and the sealing part does not need to be disassembled; dismantling the equipment The rear cotter pin must be replaced. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean workshops and clean projects.
The unpacking of the centrifugal compressor unit should be carried out from top to bottom. When unpacking, care should be taken to protect the instrument, pipeline and electrical equipment of the unit from damage. After unpacking, check the number of accessories and whether the unit is inflated or not. Leakage and other phenomena; after unpacking, drag it to the installation site together with the original box bottom plate, and the hoisting wire rope should be outside the simplified support of the evaporator and condenser, and do not make the wire rope stress on the instrument panel and pipeline; after the unit is hoisted in place, The center of the equipment should be coincident with the axis of the foundation. For two or more units in parallel, they should be on the same datum elevation line, and the allowable deviation is ±10mm; The level should not exceed 1‰, the compressor should be aligned and leveled on the main shaft, the compressor should be aligned and leveled on the middle part of the casing, the horizontal level should not exceed 1‰, and the vertical level should not exceed 1‰; Before the unit is connected to the intake pipe of the compressor, the guide vane and the actuator, the blade opening and the indicated position should be observed from the suction port, adjusted and positioned according to the requirements of the equipment technical documents, and then connected to the electric actuator; the flange connection of the unit, High oil-resistant asbestos rubber gaskets should be used; semi-hermetic centrifugal compressors have been balanced and adjusted to a good state before leaving the factory
, usually do not disassemble and clean after on-site installation, but the oil tank and oil circuit should be cleaned to ensure that the oil circuit is in a smooth state.
