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
