Frequently Asked Questions (FAQ)
What is the difference between Low Speed Mixers and Submersible Mixers?
Low Speed Mixers typically operate at lower speeds (around 420 r/min) with larger propeller diameters (up to 800mm) to generate higher thrust for large volume circulation. Submersible Mixers (QJB series) run at higher speeds (up to 980 r/min) with smaller propeller diameters (220mm to 400mm) for localized, intense mixing.
How does the mixing range speed of 0.1m/s affect system performance?
The mixing range speed diagram shows the flow velocity boundary of 0.1m/s in clear water. This value represents the effective limit of the mixer's hydraulic flow, helping to design proper spacing and avoid dead zones in the treatment tank.
What parameters should I consider when selecting a mixer model?
Key selection parameters include the motor power (kW), rated current (A), propeller diameter (mm), required thrust (N), and rotation speed (r/min). These parameters must match your tank size, liquid density, and process requirements.
How does propeller diameter impact the thrust of Low Speed Mixers?
Larger propeller diameters generate significantly more thrust. For instance, the JUNTAIMIXER3/4 with a 400mm diameter propeller produces 1400N of thrust, while the JUNTAIMIXER15/4 with an 800mm diameter propeller produces up to 3500N of thrust.
What are the typical electrical requirements for these mixers?
The rated current varies depending on the motor power. For Submersible Mixers, it ranges from 3.2A (0.85kw) to 10.3A (4kw). For Low Speed Mixers, the rated current ranges from 6.6A (3kw) up to 33A (15kw).
