An eductor is a specialized liquid tank mixing nozzles that uses a jet-driven mechanism to mix two fluids efficiently. It helps maintain a precise chemical or liquid ratio in storage tanks without requiring mechanical moving parts. In this article, we’ll explain how liquid tank mixing eductors work, their advantages, and how they compare to other fluid mixing methods.
How Liquid Jet Mixer Nozzles Work
A liquid tank mixing eductor operates using the principle of fluid dynamics, similar to how a jet orifice functions in an atomizer. However, instead of mixing air and fuel (as in an engine injector), an eductor jet mixer nozzle for tanks efficiently blends liquid from a lower level with liquid at a higher level, ensuring uniform distribution and maintaining a consistent chemical ratio.
Step-by-Step Process
- Primary Fluid Injection: A pressurized fluid is introduced through the nozzle.
- Suction Effect: The high-velocity jet creates a vacuum that pulls in surrounding liquid from the tank.
- Mixing Zone: The two liquids blend together as they pass through the mixing chamber.
- Homogeneous Output: The mixed fluid exits the eductor, ensuring even distribution throughout the tank.
Benefits of Eductors
- No Moving Parts – Reduces maintenance costs and extends lifespan.
- Energy Efficient – Uses existing fluid pressure instead of mechanical agitation.
- Uniform Mixing – Prevents chemical stratification in storage tanks.
Eductors vs Other Mixing Methods
Eductors are commonly compared to mechanical agitators and compressed gas jets for fluid mixing.
| Mixing Method | Advantages | Disadvantages |
| Eductor | Energy-efficient, no moving parts, low maintenance | Requires pressurized liquid source |
| Mechanical Agitator | High-intensity mixing, effective for thick fluids | High energy consumption, requires regular maintenance |
| Compressed Gas Jet | Works well for aeration, chemical processes | Can cause foaming, may require additional equipment |
