Liquid nitrogen and liquid oxygen charging pump location
Thread Content
Is the liquid nitrogen and liquid oxygen charging pump placed inside the tank, or is it a separate foundation outside the tank?
Just put it outside the pot. Pay attention to cold preservation measures.
When placed outside the tank, the vehicle charging pump itself does not need to be kept cold, as long as the pump inlet and outlet pipes are kept cold.
It is better to place it outside the tank. If the centrifugal pump is required to have protective facilities according to standards, it is inappropriate to put it inside the tank from the perspective of safe operation.
Reply 4# tjian I have seen an air separation layout diagram. It seems that the pump is placed in the tank. I don’t know why.
Reply 5# jinjinaaaaaaaa Does placing it in the tank mean placing it inside the storage tank or placing it under the storage tank? Ours is placed under the storage tank, which is very inconvenient to operate, and the surrounding oxygen concentration is too high during the pre-cooling pump, which is not safe. Although there is no clear requirement not to place it under the storage tank, some units do design and install it. However, according to the actual situation of the unit, I think it is better to put it outside the storage tank!
