Cryogenic liquid pump

According to different working principles, cryopumps are mainly divided into two types: reciprocating and centrifugal.

In cryogenic air separation, it is mainly used to transport liquid products, such as liquid oxygen pump, liquid nitrogen pump and liquid argon pump and other product pumps. Process pumps are also set up in the air separation process, for example: liquid oxygen circulation pump in the main cooling explosion-proof system; when the upper and lower towers are separated, the liquid oxygen at the bottom of the upper tower is sent to the main condensing evaporator at the top of the lower tower; The crude argon column is divided into crude argon column I and crude argon column II, and a liquid argon pump is arranged between the two columns.

With the development of air separation technology, cryogenic liquids have been widely used and developed.

Using in air separation plant

1- For liquid circulation

2- Extract the liquid from the storage tank and press it into the vaporizer, and send it to the user after vaporization
