潛水射流曝氣機選型
建議從五個方面加以考慮，既液體輸送量、揚程、液體性質(zhì)、管路布置以及操作運轉(zhuǎn)條件等。
1、流量是選射流曝氣機的重要性能數(shù)據(jù)之一，它直接關系到整個裝置的的生產(chǎn)能力和輸送能力。如設計工藝能算出離心曝氣機正常、較小、較大三種流量。選擇離心曝氣機時，以理想流量為依據(jù)，兼顧正常流量，在沒有理想流量時，通常可取正常流量的1.1倍作為理想流量。    
2、揚程是選射流曝氣機的又一重要性能數(shù)據(jù)，一般要用放大5%—10%余量后揚程來選型。   
3、液體性質(zhì)，包括液體介質(zhì)名稱，物理性質(zhì)，化學性質(zhì)和其它性質(zhì)，物理性質(zhì)有溫度c、密度d、粘度u，介質(zhì)中固體顆粒直徑和氣體的含量等，這涉及到系統(tǒng)的揚程，有效氣蝕余量計算和合適泵的類型：化學性質(zhì)，主要指液體介質(zhì)的化學腐蝕性和毒性，是選用泵材料和選用那一種軸封型式的重要依據(jù)。    
4、管路布置條件指的是送液高度送液距離送液走向，吸如側(cè)較低液面，排出側(cè)較高液面等一些數(shù)據(jù)和管道規(guī)格及其長度、材料、管件規(guī)格、數(shù)量等，以便進行系梳揚程計算和汽蝕余量的校核。   
 5、操作條件的內(nèi)容很多，如液體的操作T飽和蒸汽力P、吸入側(cè)壓力PS（*）、排出側(cè)容器壓力PZ、海拔高度、環(huán)境溫度操作是間隙的還是連續(xù)的、泵的位置是固定的還是可移的。 

Submersible jet aerator

Submersible aerator

Submersible centrifugal aerator

The deepwater self-priming self-coupled submersible jet aerator is a type of wastewater device that aerates the aeration tank and is a type of aeration device for the biological wastewater treatment system of the wastewater activated sludge process. The mud and water mixture is pumped into the nozzle of the incident aerator by a water pump, and is sprayed at a high speed. In the jet aerator, the oxygen transfer process is realized by directly inhaling compressed air (or air) around the nozzle of the jet aerator. Mixing with the muddy water mixture and vigorously stirring in the manifold, the bubbles are pulverized into a mist, and then in the diffusion tube, the tip becomes a pressure head, the fine bubbles are further compressed, and the oxygen is quickly transferred to the mixture, thereby strengthening Oxygen transfer process, oxygen transfer efficiency can be increased to 30-35% or more

main feature:

● Self-repositioning, easy to install, free to arrange without interrupting the process operation

●The design is compact, and the self-priming function does not require an external air source;

●The host diving operation reduces the floor space and the noise is small;

● It can be used directly in oxidation ponds to save infrastructure costs;

● Independently moving aeration device, which has a stirring function when aeration;

●The chassis can be specially designed according to user requirements.

The main advantage:

●Underwater motor with submersible motor sealing technology;

●The impeller and the motor are directly connected, the structure is simple, the efficiency is high, and the service life is long;

●It can be added with a mesh inlet to prevent foreign matter from entering the body and causing unnecessary damage;

● The intake air amount can be adjusted through the intake valve;

● In addition to the motor, other parts are available in stainless steel, carbon steel and cast iron.

main application:

The submersible jet aerator is used in the aeration tank, aerated grit chamber, pre-aeration tank, aerobic nitrification tank aeration and oxygenation mixing and aquaculture pond oxygenation in various sewage treatment projects.

Submersible jet aerator selection

It is recommended to consider five aspects, such as liquid delivery volume, head, liquid properties, piping layout, and operating conditions.

1. Flow rate is one of the important performance data of the selected jet aerator, which is directly related to the production capacity and conveying capacity of the entire device. For example, the design process can calculate the normal, small and large flow rates of the centrifugal aerator. When a centrifugal aerator is selected, the normal flow rate is based on the ideal flow rate. When there is no ideal flow rate, 1.1 times the normal flow rate can be taken as the ideal flow rate.

2. The lift is another important performance data of the jet aerator. Generally, it should be selected by amplifying the lift by 5%-10%.

3, liquid properties, including liquid media name, physical properties, chemical properties and other properties, physical properties are temperature c, density d, viscosity u, solid particle diameter and gas content in the medium, etc., which involves the lift of the system, effective Calculation of cavitation allowance and type of suitable pump: chemical properties, mainly refers to the chemical corrosiveness and toxicity of the liquid medium, which is an important basis for selecting the pump material and selecting the type of shaft seal.

4. Pipeline layout conditions refer to the liquid feeding height, the liquid feeding distance, the lower liquid level, the higher liquid level on the discharge side, and other data and pipe specifications and their length, materials, pipe fittings specifications, quantity, etc. In order to carry out the calculation of the combing process and the checking of the NPSH.

 5. There are many operating conditions, such as liquid operation T saturated steam force P, suction side pressure PS (absolute), discharge side container pressure PZ, altitude, ambient temperature operation is gap or continuous, pump position is fixed Still removable.
