Overview

NCW submerged Roots blower is a high-performance, low-noise fan designed and produced independently by Shanghai Enze Machinery Equipment Company, which is suitable for current environmental protection requirements. $r $n1. Lower energy consumption: Submerged blowers reduce the heat dissipation holes of the bearing seat due to sinking into the water, which in turn reduces pressure loss and improves overall efficiency. $r $n2. Tranquility: During operation, the blower's sound is refracted into the water at the interface between air and water, rather than entering the air. At the same time, the water and the groove wall also refract back to achieve the effect of sound suppression. $r $n3. No need to create a machine room: Submerged blowers are not required as they are placed in water

Product Details

NCWEnergy saving and consumption reducing, low noise, simple and practical maintenance!

1.*A fully enclosed straight structure that seals off noise, and a submerged blower that sinks to the bottom of the water. After the noise is absorbed through water barriers, it can be reduced;

2.Less faults: adopting direct power transmission, no need for pulleys, reducing fault factors, automatically stopping operation due to overload and overheating, and automatically resetting;

3.Easy installation: The main body does not require a fixed base, the piping is short, and the installation space is small;

4.Bearings and gears are not easily damaged: The transmission gear is oil bath type, and the upper bearing is lubricated with high-temperature butter, making the bearing less prone to damage after being cooled by water;

5.No need to build a fan room: installed underwater, no need to build a fan room;

6.Uniform aeration:Connect pipelines or aerator plates with openings for aeration;

Working Principle:

NCWThe Enze brand submerged blower is modified from the Roots blower and is a Roots blower specially developed for sewage treatment that can sink to the bottom of the water.fanFor a direct structure, the rotor is a closed non-contact type, and the double axis parallel three blade impeller has a small amplitude and a long bearing life, without the need for a pulley to drive the operation. The submerged blower is installed at the bottom of the water and connected to the pipeline for aeration. The sewage treatment is carried out through aeration reoxygenation method.

Installation method:

Before installing the submerged blower, first conduct an air tightness test on the extension pipe of the submerged blower

After completing the testing, proceed with the following steps for installation:

1Connect the power supply to confirm the forward and reverse rotation of the machine

2Install two inlet and outlet extension pipes, equipped with sealing gaskets

3Conduct an air tightness test on the connection between the extension pipe flange and the muffler flange of the submerged fan

4Use stainless steel chains to lift the submersible motor hoist ring and transport the machine to the fan installation site

5Fixed submersible blower base and extension pipe

6Install inlet muffler and elbow

7Install check valve and three-way valve

8Install the elastic joint and fan main pipe
