Explosion prevention measures of liquid oxygen pump
Before starting the liquid oxygen pump for cooling, the blow valve should be open and connected to the nitrogen blow labyrinth at room temperature for 10? 20 minutes. On the one hand, the oxygen driver will leave and make the seal return to the normal temperature difference.
Turn around, make sure there is no fault, start the water pump, and pay attention to the stability of the inlet pressure of the pump. If the pressure fluctuates or the outlet pressure does not rise, cavitation may occur. It is necessary to open the exhaust valve body on the pump, continue to cool the liquid oxygen pump, and keep the pressure stable, so as to control the pressure of the sealing gas higher than that before the sealing pressure of 01005 × 0101 MPa.
