1. The structural design should be simple, reliable, and easy to disassemble and assemble.
2. In order to facilitate the disassembly, replacement and cleaning of parts, the design of the actuator should try to adopt standardized, universal and systematic parts.
3. The inner and outer wall surfaces of the equipment should be smooth and flat, without dead corners, easy to clean and sterilize. The surface of the parts should be chrome-plated to resist corrosion and prevent rust. Avoid using paint on the outside of the equipment to prevent peeling.
4. Equipment for preparing purified water should use low-carbon stainless steel or other materials that have been verified not to pollute the water quality. Equipment for preparing purified water should be cleaned regularly and the cleaning effect should be verified.
5. The materials that come into contact with water for injection must be high-quality low-carbon stainless steel or other materials that have been verified not to pollute the water quality. Materials. Equipment for preparing water for injection should be cleaned regularly and the cleaning effect should be verified.
6. The storage period of purified water should not be longer than 24 hours. Its storage tank should be made of stainless steel or other materials that have been verified to be non-toxic, corrosion-resistant, and non-leaching polluting ions. A hydrophobic sterilizing filter that does not shed fibers should be installed to protect its vent. The inner wall of the storage tank should be smooth, and there should be no dead corners or sand holes in the pipes and welds. Sensors that display parameters such as liquid level, temperature and pressure that will not cause stagnant water pollution should be used. The storage should be cleaned, disinfected and sterilized regularly, and the cleaning and sterilization effects should be verified.
7. Transportation of pharmaceutical water
(1) Purified water and pharmaceutical water should be transported by stainless steel pumps that are easy to disassemble, clean and disinfect. In cases where purified water and water for injection are required to be transported by compressed air or nitrogen, the compressed air and nitrogen must be purified.
(2) Purified water should be transported by circulating pipelines. The pipeline design should be simple and blind pipes and Dead corners. Pipes should be made of stainless steel or other pipes that have been verified to be non-toxic, corrosion-resistant, and non-leaching polluting ions. Valves should be sanitary valves without dead corners, and the flow direction of purified water should be indicated.
(3) Pipes and pumps for conveying purified water and water for injection should be cleaned, disinfected and sterilized regularly, and can only be put into use after verification.
8. The design of pressure vessels must be undertaken by licensed units and qualified personnel, and must be handled in accordance with the relevant provisions of the National Standard of the People's Republic of China "Steel Pressure Vessels" (GB150-80) and the "Regulations on Safety Technical Supervision of Pressure Vessels".
