Duan Environmental Protection QXB type centrifugal submersible aerator, easy installation, long service life, used for sewage oxygenation and circulation.

The aerator of the centrifugal submersible aerator is designed with a compact structure, eliminating the need for an external air source with its self-priming function. The main unit operates submerged to reduce area and noise. It is installed and used with a silencer equipped with an intake pipe, voltage 380V, and comes with an on-site stainless steel control cabinet for installation and use.

The submersible aerator can be used directly in oxidation ponds, saving infrastructure costs. Additionally, the chassis of this product can be designed according to user requirements.

The submersible aerator is an oxygenation device developed based on the introduction of submersible motor sealing technology and its own development of submersible aerators. This machine has multiple functions in one unit (high-speed aeration and low-speed mixing), which can serve as an aeration and mixing device in various sewage treatment processes, especially in deep pools (with depths up to 20m).

QXB Type Submersible Centrifugal Aerator Product Use:  

Use of Centrifugal Aerator QXB type centrifugal submersible aerator is used in sewage treatment plant aeration tanks and aeration grit chambers for oxygenating and mixing sewage mixtures, as well as for biochemical treatment of sewage or oxygenation in aquaculture ponds.

Selection of Submersible Centrifugal Aerator:

It is recommended to consider factors such as liquid delivery volume, head, liquid properties, pipeline layout, and operating conditions.

1. Flow rate is one of the important performance data for selecting a centrifugal aerator, directly related to the production and delivery capacity of the entire system. If the design process can calculate the normal, minimum, and maximum flow rates of the centrifugal aerator. When selecting a centrifugal aerator, base the selection on the maximum flow rate, while also considering the normal flow rate. In the absence of a maximum flow rate, usually 1.1 times the normal flow rate can be taken as the maximum flow rate.    

2. Head is another important performance data for selecting a centrifugal aerator, generally selected with a margin of 5%—10% added to the head.   

3. Liquid properties, including the name of the liquid medium, physical properties, chemical properties, and other characteristics. Physical properties include temperature c, density d, viscosity u, diameter of solid particles in the medium, and gas content, etc., which relate to the system's head, calculation of effective NPSH, and selection of the appropriate pump type. Chemical properties mainly refer to the chemical corrosiveness and toxicity of the liquid medium, which are important bases for selecting pump materials and the type of shaft seal.    

4. Pipeline layout conditions refer to data such as liquid delivery height, delivery distance, delivery direction, the lowest liquid level on the suction side, discharge side liquid level, as well as pipeline specifications, length, material, pipe fitting specifications, quantity, etc., to facilitate calculation of system head and verification of NPSH.   

5. Operating conditions include many aspects, such as the operating T of the liquid, saturated vapor pressure P, suction side pressure PS, discharge side container pressure PZ, altitude, ambient temperature, whether operation is intermittent or continuous, and whether the pump position is fixed or movable.
