Filled with high-purity helium.
Professional practitioners are required to fill high-purity helium while strictly abiding by the high-purity gas filling process regulations and safety operation procedures.
1. High-purity gas filling operators must wear protective equipment that meets the requirements when working. Before operation, check whether the filling equipment, pipes, valves, instruments, instruments and work card instruments are complete, complete, safe, sensitive and reliable.
2. Because all kinds of gas cylinders contain different working mediums and withstand pressure in different environments, their safety conditions will change, and even adverse changes will occur. In order to ensure safety, the various cylinders in the service must be subject to regular technical inspections and evaluations in strict accordance with the specified time and content. The high-purity helium inflator must be inspected before each filling.
3. Strengthen the level of equipment maintenance, and the equipment cannot be positioned as "usable" level. Due to the quality and maintenance of the compressor, the compressed air quality produced by this unit is not up to standard for a long time. However, it always meets the barometric standard, ignoring the qualified temperament. The oil-water separator and dryer have not been maintained or replaced for a long time, resulting in a decrease in the ability to remove water and oil, and the corrosion of gas cylinders has increased, burying the hidden danger of future accidents.
4. Strengthen personnel training, organize technical backbones, especially veteran comrades with certain practical experience, summarize lessons and lessons, continuously accumulate good working methods, implement equipment operating procedures and safety systems, and avoid serious accidents caused by equipment damage or work loss due to weak personnel skills.
5. When operating the valve, the operator must stand on the side of the valve and proceed slowly, opening or closing it at one time, but not too tightly, so as not to produce too much frictional heat or static electricity, resulting in the combustion of combustible gas or gas cylinders. Excessive force can also damage the threads of the valve body.
6. Starting from the inflation of high-purity helium, the change of pressure should be observed at any time. When the pressure rises to 1 3 of the inflation pressure, the operator should test the temperature of the bottle and deal with the leak. If any abnormality is found, it should be dealt with in time to make the cylinder inflate normally until the inflation is completed. If some cylinders are found to be unfilled (the walls of the cylinders are not heated by touching the cylinder with your hands) or leaks during the inspection, they should be dealt with in time. If there is no air intake, check that the cylinder valve is open;If there is a leak, the leak should be treated, but when the pressure exceeds 10MPa or it is inconvenient to handle, the inflation valve and the cylinder valve should be closed after the cylinder is inflated, and then check whether the catheter is normal. In addition to touching with your hands.
