PCB’s sensors are the ideal solution for monitoring cryogenic pumps as they can operate in extreme low temperatures.
Cryogenics is generally defined as temperatures below -180 °C. Several common industrial gases and fuels such as argon, helium, hydrogen, nitrogen, oxygen, natural gas and propane gas have a boiling point low enough to classify them as cryogens. These cryogenic gases and fuels are transported and used in their liquid state for a variety of industrial applications.
Cryogenic centrifugal and reciprocating pumps are required to effectively transfer the liquid gas between tanks.
These applications include:
- Liquefied natural gas (LNG) processing
- Industrial gas processing (argon, helium, hydrogen, nitrogen and oxygen)
- Pharmaceutical production (statin drugs, biotech products such asvaccines)
- Frozen food production/storage
Regardless of whether the cryogenic pump is submerged or mounted in an exterior suction vessel, these pumps can suffer the same types of faults as their noncryogenic equivalents. These can include:
- Acoustical resonances
- Cavitation
- Impeller eccentricity and imbalance
- Impeller/diffuser clearance
- Oil whirl
- Recirculation
- Structural resonances
- Wear ring clearance
PCB’s range of cryogenic sensors can help you monitor, uncover and correct these conditions before they become a serious problem.
