What is a Venturi Injector
How Venturi Injectors Work and Venturi Injectors Structure
1. How Venturi Injectors Work
A fluid under a certain pressure flows through the nozzle, Converting fluid static pressure energy into kinetic energy, Create a certain negative pressure, Simultaneously transferring kinetic energy to the second fluid, Achieve the purpose of suctioning
the second fluid.
Two fluids mix within the jet mixer, The mixture is discharged after passing through the expansion pipe. The diffuser reduces the flow velocity of the mixed fluid while increasing static pressure to minimize losses.
Achieve the requirements for fluid transport and mass transfer throughout this process.
2. Venturi Injectors Structure
The typical structure of Venturi Injector consists of : nozzle, inlet chamber, throat, and diffuser.
The structural proportions vary significantly depending on different applications.
Venturi Injectors emphasizing mass transfer.
1. Large specific surface area between mass transfer fluids (small bubbles)/
2. Jet turbulence has a strong diffusion effect.
Venturi Injectors with emphasis on conveying.
1. The driving fluid is in full contact with the entrained fluid.
2. Minimal momentum loss.
