The self-pressurized liquid nitrogen tank appears as a conventional liquid nitrogen tank filling container. It has its own booster system. The pressure in the tank is its working power. Filling, but what if the pressure of the self-pressurized liquid nitrogen tank keeps going up?

1. Check the booster valve to see if the booster valve is open

If it is not fully opened, just open the valve directly;

If the booster valve is open and frost is seen on the pressure building evaporator touching the bottom of the tank, the valve should be closed immediately, possibly a leak from the container.

2. Use the leak detection method to check the connection. If there is frost, it means the container is leaking, and immediately report to the superior or contact the manufacturer.

2: slightly open the booster valve

3. The pressure regulator is not high enough, just adjust and increase the pressure.

The above are the three reasons why the pressure of the self-pressurized liquid nitrogen tank cannot go up and the solutions. After that, everyone should know what to do!
