Cryogenic liquid pumps are machines used to transport cryogenic liquids and increase their pressure. According to the principle of action, cryopumps can be divided into two categories: vane type and reciprocating type. The vane type includes centrifugal, mixed flow and axial flow. The reciprocating type has a plunger type and a piston type.
Centrifugal pumps are the most commonly used type of vane type. Centrifugal has single-stage and multi-stage points. The plunger pump is the most commonly used one in the reciprocating type, and it is divided into single-row and multi-row.
Centrifugal cryopumps are mostly used for low and medium pressure transportation. Column cryopumps are used in systems with high pressure and low flow.
Cryogenic liquid pumps should pay attention to the following issues in the structural design:
(1) In order to ensure uniform cold shrinkage of parts at low temperature, the structure should be symmetrical;
(2) The inlet and outlet pipelines of the pump must be provided with compensation for cold shrinkage, such as compensation for metal bellows;
(3) The connecting parts between the normal temperature area and the low temperature area should be made of materials with low thermal conductivity to reduce heat conduction loss.
