Submersible Roots Blower
Submersible Roots Blower
Description
Submersible-type Roots Blower
Feature
  1. Compact
  2. Much quieter when submerged, without the need for added soundproofing.
  3. Strict management of quality standards. For convenience, the motor and blower’s body are connected as one to avoid conveyor installation.
  4. Both motor and the blower are entirely sealed with an o-ring to ensure waterproofing and a special outer case can easily be removed in case of over heating.
  5. Technical customization (size, pressure, design, pump accessories.
  6. Assembled using state-of-the-art CNC machinery enabling precise measurements and grinding needed for more efficient pumping.
  7. Fewer vibrations transmitted through the lobe, for longer-lasting shafts, gears and bearings.
  8. Three-lobe design controls any backflow pressure towards rotor.
  9. Oil and dust-free outlet.
  10. Lubricated with high grade oil, proven to be a much better alternative to grease.
  11. Significant improvement in air performance ratios: wider air, pressure and vacuum range, more stable flow, fewer pressure variations.
  12. Lower energy consumption.
  13. All our products can be used for OEM.

Application
  1. Waste water treatment plants.
  2. Electroplating tanks.
  3. Activated sludge systems.

Suitable Place

Draining Tank, Defoaming Tank and Blowing Tank
  • Advantages :
    For more convenient monitoring, install in shallow waters.
    The oil can be changed while the system rests in the tank, as the water has been emptied.

  • Cautions :
    The volume of water should be kept above the minimum threshold.
    The temperature of water should be kept below 32oC
Aeration Tank
  • Advantages :
    Shorter pipes and easier installation.

  • Cautions :
    Do not install the blower in a place where air or water circulation might be interrupted. Make sure to leave enough of a gap between diffuser and pump so as to prevent direct flow of bubbles to the motor/pump.
Key Point of Installation :

  • To install the blower, use a cable or chain to drop it to the bottom of the tank. Place it on the base (there is no need to use fixing bolts).
  • Use a fixing skeleton to prevent the inlet and outlet pipeline from loosening.
  • A hanger and a hanger hole are necessary for convenient installation and management.
  • When you need to use the blower, insert the hanger in the hanger hole. Pull the hanger out of the designated hole when the blower is not in use.
  • When the blower begins to operate, open the safety valve to the full before adjusting the required pressure.
Caution in installation

Caution in installation

For monitoring, adjustments or repairs, place the blower in a convenient location. To prevent adverse flow in case the blower stops, add a check valve. If possible, install the check valve at a position higher than the water level in the aeration tank. If placed in a tank containing lots of sludge, place a tertiary airflow pipe (from outlet) on the side of the machine, with the tip facing away from it, so as to prevent unwanted build-up of dirt on the apparatus by creating a constant circulating flow of water around it. Machines that are not regularly cleaned will over-heat, resulting in possible breakdown.

Cautions in Inlet and Outlet

The inlet muffler should be erected and installed outside the tank, ensuring that it takes in air with little or no humidity (as shown in drawing [1])

The inlet muffler should be installed at least 1 meter above the ground in an open area enabling easy cleaning if dust accumulates.
As shown in drawing [2], damp air from the tank into the muffler will result in the building up of rusty lobes and cause a breakdown.

Any spare blower should be stored in a dry place to avoid humidity build-up. If stored in a damp place, run it two-three times per week to clear humidity and avoid rusting.
