Working principle of carbon dioxide cryogenic pump
The carbon dioxide cryogenic pump is usually a rotor-type positive displacement pump.
The carbon dioxide cryogenic pump is usually a rotor-type positive displacement pump. The spiral grooves on the active rotor and the driven rotor mesh with each other, and they cooperate with the inner surface of the three holes of the bushing to form several levels of dynamic sealing chambers between the inlet and outlet of the pump. These chambers continuously move the liquid axially from the pump inlet to the pump outlet, and gradually increase the pressure of the transported liquid, thereby forming a continuous, stable, axially moving pressure liquid.
In order to reduce heat transfer, the pump body is usually equipped with an insulation device to ensure that the low-temperature liquid carbon dioxide will not be vaporized due to the input of external heat during the transportation process, ensuring the transportation efficiency and safety.
