Air quantity unit
Adjustable air flow control for pneumatic conveying
Applications
This automatic control unit enables in particular the safe operation of slow motion conveying by providing pre-calculated air quantities at any time and under any operating conditions. The small window for careful and reliable transport of solids is secured by a combination of off-the-shelf regulators and air quantity measuring instruments with a micro processor unit.
Advantages
- Easy set point setting for required air flow
- Programmable conveying modes for different conveying lines
- Programmable conveying parameters for different product characteristics
- Compensation of air leakage of rotary feeder depending on conveying pressure
- Individual adjustments depending on conveying pressure, conveying line, rotary feeder size
- Integrated process for gentle purging with higher air velocities
- Fluctuations of mass flow up to 1:10 automatically regulated (depending on conveying length)
- Even suited for low mass flow in large pipes
- Efficiency of 95 % in comparison to 85 % with sonic chokes
- Noise-optimised
- Automatic pressure control for safe relief of high pressure and pressure peaks
- Interface to main controls with Profibus DP, digital in-/output or as stand alone unit
