The reasons why the rated power and pressure of the low-temperature liquid pump cannot be reached are as follows:

1. Cavitation or binding of the pump;

2. Impeller or volute blockage;

3. The heating before starting the pump is not qualified, and there is moisture inside the pump;

4. Damaged sealing ring and impeller;

5. The pressure after discharging the system is higher than the rated value.

Solution:

1. Improve inlet conditions, clean inlet filters, and ensure complete exhaust;

2. Clean up the blocked parts;

3. Remove moisture from dry and heated gas;

4. Replace the damaged parts;

5. Check the characteristic curves of the pump and discharge system, and improve the system pipelines.

In the main column of the air separation column, the distribution of argon varies with the position of the liquid air inlet. With the increase of liquid air inlet position, the maximum concentration of argon enrichment zone in the stripping section also increases, and the nitrogen content in the distillate can be reduced. However, the argon content in the downstream also increases. In order to ensure the purity of oxygen, more trays are needed under the extraction port of argon fraction. Therefore, in the case of producing argon, the position of liquid air supply E1 should be appropriately increased compared with the case of not producing argon. Some unit is equipped with two liquid air inlet positions to meet the conditions of argon production and non argon production respectively. In the production of argon, in order to improve the extraction rate of argon, the content of argon in oxygen and nitrogen must be reduced. When the content of argon in exhaust nitrogen is more than 0.3%
