The stainless steel liquid nitrogen tank is also a self-pressurizing liquid nitrogen tank. The tank itself has a pressurizing system and is adjusted through a pressurizing valve. When the booster valve opens, the pressure increases, and when it closes, the pressure decreases. During use, what is the reason why the booster valve is opened but unable to boost pressure?
The reasons why the pressure does not rise after the booster valve of the self-pressurized liquid nitrogen tank is opened are as follows:
1. The booster valve is damaged
When the vent valve and the inlet and outlet valve are closed, and the pipeline is unobstructed but does not pressurize, it means that there is a problem with the booster valve itself and the booster valve needs to be replaced. You can contact the manufacturer for replacement.
2. Pipe blockage
The main reason for pipeline blockage is that external air and moisture enter and are not discharged in time. Under the influence of low temperature in the tank, they condense into ice and block the pipeline.
The correct way to clear the pipe is to use hot nitrogen or hot air to blow away the ice and clear the pipe. After unblocking, it is recommended to transport liquid nitrogen to test whether it is unblocked. Do not use tapping to unblock.
3. Insufficient pressure
Check whether the pressure in the liquid nitrogen tank is sufficient. If the pressure in the liquid nitrogen tank is too low, the pressure cannot be increased even if the pressure increase valve is opened.
4. Container leakage
The container leaks and the vacuum is destroyed, which will also result in the inability to pressurize.
It is easy to judge whether the container is leaking. You can observe the frosting phenomenon on the tank body. The location of a large area of frost is the leakage location.
At this time, the jar can no longer be used normally. You can contact the manufacturer for after-sales treatment.
In short, there are many reasons why the pressure does not rise after the booster valve of the self-pressurizing liquid nitrogen tank is opened. Check them one by one to find out and solve the problems.
