There should be sealing measures between them; the pipes should be arranged neatly, and the installation of valves, pipe racks and pipe supports should be reduced. When the temperature is determined, the temperature of the outer wall of the cold insulation pipeline shall not be lower than the dew point temperature of the environment; the surface of the insulation protection layer of the pipeline shall be flat and smooth, and no particulate matter shall fall off; all kinds of pipelines in the clean pharmaceutical cleanroom shall be provided with the name and flow direction of the conveying material. logo.
The machinery used for the packaging of finished products should be reliable in performance, easy to operate, and should not cause errors. When unqualified, foreign matter mixed or performance failure occurs, it should have functions such as alarm, correction, rejection, adjustment, etc. The instruments and meters on the equipment should be The measurement should be accurate, the accuracy should meet the requirements, and the adjustment control should be stable; the surface of the insulation layer of the equipment should be smooth and clean, and no foreign matter should fall off. The insulation layer installed in the clean room should be protected by a shell made of stainless steel or other non-polluting clean room materials. And it can withstand daily cleaning and disinfection, and must not react chemically with disinfectants; when the equipment is installed in clean workshops with different cleanliness levels, sealing and partitioning measures should be adopted; all kinds of equipment in the clean pharmaceutical cleanroom should use low-noise products. , for equipment whose noise exceeds the allowable value of the medical clean room, special noise reduction facilities should be set up; the conveyor belt used in the air cleanliness class A and B clean room shall not pass through the lower level area, unless the conveyor belt itself can be continuously sterilized; pharmaceutical equipment and other Active vibration isolation measures should be taken when equipment or pipelines with strong vibration are connected, and passive vibration isolation measures should be taken in areas where precision equipment and instruments are installed according to the impact of various vibration sources.
