Pay attention to safety when manufacturing air separation equipment!

1. Before starting, the temperature of liquid oxygen pump should be turned on for 10 minutes, and then the device should be cooled to room temperature;

2. After steering, make sure there is no fault. Start the water pump and pay attention to the stable inlet pressure of nitrogen generator pump. If the pressure swing adsorption nitrogen production occurs shaking or the outlet pressure does not rise, cavitation may occur. The exhaust valve on the pump must be opened to continue cooling the LOX pump. The pressure of sealing gas is higher than that before sealing 01005? 0101 MPa;

3. In the seal gas pipeline, first adjust the nitrogen generator to the corresponding pressure, and then open the inlet and outlet valves of the pump to cool the liquid oxygen into the pump. The seal gas pressure must be higher than the inlet pressure

0105 MPa。
