Precautions for increasing and decreasing the expansion machine capacity
Thread Content
Question! In the process of feeding pressurized and expanded air into the upper tower, what considerations should be taken when increasing or decreasing the amount of expansion? Thank you!
Pay attention to controlling the opening degree of the backflow valve in order to maintain a relatively stable change in the speed of the expander
1. Coordinate well with the compression team to ensure the appropriate pressure is output by the air compressor. 2. Pay attention to the operation of the expander. It includes some parameters: such as oil pressure, seal gas pressure, etc.
Same opinion as above: be sure to pay attention to the booster pump and air compressor.
Pay attention to the air compressor exhaust pressure and bearing oil pressure. At the same time, attention should also be paid to the gas flow rate and exhaust temperature of the expander.
When adjusting the expansion amount, special attention must be paid to the argon column; changes in the expansion amount directly affect the reflux ratio in the upper column, which in turn causes fluctuations in the argon-rich zone. Therefore, it is essential to closely monitor any changes in the argon column.
