Common faults of air separation unit system
Air separation unit maintenance procedures need to determine the maintenance cycle and content, maintenance quality standards, commissioning and acceptance maintenance and troubleshooting. Before the maintenance, the staff should prepare the air separation unit maintenance procedures according to the regulations, so as to avoid missing items and causing unnecessary economic losses. The staff should be familiar with the common faults of air separation unit system and deal with the emergency situation in time.

DEAR air separation has cooperated with customers in metallurgical industry domestic and abroad in many projects, and has rich project experience. DEAR has continuously invested in the research and development of large-scale air separation plant. In view of metallurgical industry, DEAR combined with the characteristic of this industry, develops high-efficiency energy-saving air separation plant, to meet the needs of large and medium customers. DEAR air separation uses the rapid development of internet technology to establish a remote monitoring system to collect real-time operation data of each air separation plant, and provides the best suggestions for users by using big data analysis.
Large air separation plant KDON-16000/35000 solution for metallurgical industry
Metallurgical industry is an industry to develop metal mineral resources and produce various kinds of raw materials for metal products. With the progress of science and technology, the metallurgical industry has new requirements for the process, process, management and application research and development of air separation plant. The air separation plant also has the following development trends: first, large-scale and cluster; second, the core technology is gradually localization; third, refinement, which needs to develop high-efficiency energy-saving technology for different application fields; fourth, highly automated and intelligent, reduce manual operation as far as possible, and gradually establish a remote monitoring system by using the rapid development of internet technology to collect in real time according to the operation data of air separation plant, using big data analysis to provide the best suggestions for users, etc. KDON (Ar) - 16000 / 35000, a large scale air separat

1.Before filling alumina and molecular sieve adsorbent into the adsorber, personnel should be arranged to enter the adsorber to check whether the screen screen is damaged. If there is any damage, it must be repaired before filling. 2.The quantity of adsorbent should be counted during loading and unloading, and the packing barrel and bag of adsorbent should be prevented from being damaged, and the adsorbent should be prevented from getting damp due to poor sealing. 3.The molecular sieve in the container should be filled in dry weather without rain. Personnel entering the container shall wear oil-free work clothes and caps and clean soft soled shoes.

The main causes are as follows: 1. The structure is unreasonable, the welding seam is concentrated and the welding joint stress is too large. 2. When welding, the molten pool is too large and overheated, and the alloy is burnt too much. 3. The arc crater is not filled due to too fast arc closing and too early wire drawing. 4. Material problems, for example, when Mg content is less than 3%, and impurities such as Fe and s exceed the standard, it is easy to cause cracks. When the melting temperature of welding wire is too high, liquefaction cracks in heat affected zone are easy to occur. Preventive measures include: 1. During the design, attention should be paid to the reasonable arrangement of welding seams, avoiding the stress concentration as far as possible, and selecting the welding sequence reasonably. 2. Reduce welding current or increase welding speed properly. 3. The arc stopping operation technology should be correct, and the arc pit should be filled by adding the ou
