Cryogenic liquid pumps have a wide range of applications

Date:2022-09-22
A cryogenic liquid pump is a mechanical device used to introduce liquid into a system. It works by introducing a cryogenic fluid into an accumulator. This accumulator can be a pressure vessel, or it can consist of fluid conduits and manifolds. The accumulator is filled with liquid, which is then introduced into the pump when pressure is reduced.
A cryogenic liquid pump produces a radial force on the liquid being pumped. This force is influenced by the asymmetry of the surrounding flow field. The radial force is proportional to the degree of rotation of the impeller, which is measured in degrees. 
Cryogenic liquid pumps have a wide range of applications. These include transportation of liquid hydrogen and liquid natural gas, cooling systems in spacecraft, and injection of cryogenic fuel in aerospace propulsion systems. The basic principles of cryogenic liquid pumps are largely the same as those of conventional vacuum pumps, although there are some differences.
The main components of a cryogenic liquid pump are the impeller and the motor. These two components work together in a vertical system that is immersed in cryogenic liquid. The impeller-rotor is connected to the SMB via an axial-flux disk motor. The impeller rotates frictionlessly, thereby minimizing the likelihood of mechanical resonance.

The pump is mainly composed of a motor, electric control cabinet, pulley, transmission case, and cold end, which are assembled on the common base.
The pump adopts materials with good wear resistance as the piston ring and guide ring, so its working life is prolonged. The seal is composed of sealing material with excellent sealing performance, which ensures that the pump can operate reliably and without failure for a long time under normal working conditions.
The pump has a novel structure, excellent material, exquisite processing, stable performance, easy operation, convenient maintenance, and long service life;
