In the pharmaceutical industry, in order to improve the quality of drugs, whether it is the production of large infusions, injections, powders, freeze-dried preparations or oral liquid preparations, nitrogen filling processes are required. At the same time, economical options for nitrogen use and compliance with GMP requirements have always been the focus of pharmaceutical production. In the past, most of the nitrogen used in pharmaceuticals came from industrial nitrogen in cylinders, or from standard forms of liquid vaporization. With the modernization of my country's pharmaceutical industry and the development of pharmaceutical machinery, on the basis of the introduction of nitrogen technology, my country's pressure swing nitrogen suction machine has opened up a new field of pharmaceutical nitrogen. Correct and safe use of pressure swing nitrogen suction machine should pay attention to the following points: 1. The nitrogen production system must be transported in sections, and the equipment should be kept stable during transportation. Collision is strictly prohibited. 2. Before starting the machine, the entire nitrogen production system should be carefully checked to ensure that there are no tools, parts or other objects in the air compressor. 3. Before the operation of the nitrogen generator, the opening of the hose must be fixed to prevent the hose from hurting people. 4. When starting the nitrogen generator, the exhaust valve should be in an empty state to avoid overpressure of the air compressor. 5. When removing any pressure components, ensure that the entire system is in a pressure-free state. 6. Regularly check the reliability of safety devices (such as safety valves). 7. The maintenance of the nitrogen generator must be carried out under the condition of shutdown and power failure.
