Checking whether the cooling water circulation of the air separation equipment is fully connected is an important step to ensure the normal operation of the equipment.
Observe the operation status of the cooling water system, check that the water level in the water tank is normal, and there are no leaks or abnormal drops. Observe the flow of water and observe the flow of cooling water through transparent pipes or observation windows. Check the connection of the pipeline, inspect all interfaces of the cooling water pipeline one by one, and ensure that there are no leaks or looseness at the interfaces; Check that the installation bracket of the pipeline support is stable and not loose. Check the valve status and ensure that all valves in the cooling water system (such as globe valves, regulating valves, check valves, etc.) are in the correct working condition. Detect the flow rate and pressure of cooling water, install flow meters and pressure gauges, and compare the design parameters. Check the water quality of the cooling water and regularly test the water quality: Take samples regularly to test the water quality of the cooling water, including indicators such as pH value, turbidity, hardness, chloride ion content, etc. Clean and replace the cooling water, promptly clean the cooling system and replace it with new cooling water based on the water quality test results. Replacing with new cooling water can prevent water quality deterioration from causing damage to the system.
Comprehensive inspection and debugging, comprehensive inspection, on the basis of completing the above inspections, conduct a comprehensive inspection of the cooling water system. Ensure that the cooling water system can operate normally.
