The Liquid Ejector system is different from the traditional steam ejector system because its motive fluid is a liquid rather than the traditional steam.
What to expect
The Liquid Ejectors are Venturi jet devices. The motive liquid is flowed through the nozzle and into the mixing chamber. As the cross-sectional area of the mixing chamber is reduced, the velocity of the liquid is increased.
IN OTHER WORDS, POTENTIAL ENERGY IS CONVERTED INTO KINETIC ENERGY, OR STATIC PRESSURE IS TRANSFORMED INTO DYNAMIC PRESSURE. AS THE LIQUID ACCELERATES, THE STATIC PRESSURE DECLINES.
This generates a vacuum, which diffuses the gas into the mixing chamber. As the gas/liquid mixture enters the diffuser, the static pressure begins to recover. The gas is now compressed as it approaches the discharge. Thus, the Liquid Ejector acts as an evacuator as well as a compressor.
Using a liquid as a motive fluid has several benefits:
user-friendly operation and easy maintenance
a liquid motive medium is used to suck off another liquid and to convey it to a higher pressure
- high turbulence ensures a homogeneous intermixture of both flows
