Product Description

Product Description

Blowers are the heart of the aeration system in a wastewater treatment plant. Their primary function is to supply a large volume of air to the aeration tanks. This air provides essential oxygen for the aerobic bacteria that break down and consume organic pollutants in the wastewater.

The two most common types are Positive Displacement Blowers (like Roots blowers) and Centrifugal Blowers. Positive displacement blowers are often preferred for smaller plants or applications requiring constant airflow against varying pressure. Centrifugal blowers are more energy-efficient for larger plants with higher capacity demands.

Key selection factors include airflow rate, pressure, energy efficiency, and reliability. Efficient blower operation is critical, as aeration typically accounts for 50-70% of a plant's total energy consumption. By ensuring optimal oxygen transfer, blowers directly impact treatment effectiveness and operational costs.

Specification

Applications

1.Aeration of swage

2.Clean up the bottle's dead angle by gas

3.Use gas spraying fire-resistant material on the wall

4.Increasing oxygen in water

5.Use for combustion, increasing oxygen to promote combustion

6.Increasing oxygen to promote the fermentation

7.Use washing fluid washing car base on siphon principle

8.The mechanical arm carrys the paper after it has been rised by the wind

9.Use gas blowing sand to flush pipes

10.Stir gas liquid,nake its uniformity

11.Do body massage, promote the blood circulation

Features

1.Helical synchronous gear: smooth operation and low noise.
2.All bearings are the Japanese NSK bearing.
3.The oil seal is used CR seal imported from USA.

4.Cooling way is air-cooling and water-cooling.

5.The impeller uses the impeller & shaft integrated structure , high aceuraey.

6.Compaet structure, the same inlet and outlet impeller structure, flexible installation.

7.There are various installation ways. The air blower can be installed into horizontal airinlet and vertical air inlet using the same bottom base frame.
8.It can also change the position of the drive shaft, right shaft or left shaft drive, uppershaft or lower shaft drive.

Working Principle

SL Double oil tank three -lobe Roots blower is a positive displacement blower

There are two impellers on the two parallel shafts. There are some tiny gap between impeller to bodycasing, impeller to impeller
The impellers rotate in opposite direction, a certain air will be absorbed at inlet port and transferred to blower's outlet port

Each impeller always keeps the correct phase by the synchronous gears, not touching each other. So they can rotate at high speed without any lubrication inside, And it is simple structure, running smoothly, performance stabilization.
