Product Description
Introduction of submerged jet aerator Deep water self-priming submersible jet aerator is characterized by stirring and aeration of water at the same time, with fine and dense bubbles. It can not only obtain high oxygen transfer rate, but also has the advantage that the impeller is not blocked. The strong unidirectional liquid flow leads to effective convective circulation, and the motor load changes less with the water level, so it is suitable for pools with large water level changes. The aeration depth of diving can reach 10m without compressed air. Low cost, easy installation and maintenance.
It main scope of application is as follows:
1. Deep water aeration;
2. Aeration and mixing of biochemical tank;
3. Sludge aeration and mixing;
4. High concentration organic wastewater treatment process.
1, Product overview
QSB submersible jet aerator is used in aeration tank and aerated grit chamber of sewage treatment plant. The mixed liquid of sewage and sludge is oxygenated and mixed, and the sewage is biochemical treated or cultured to increase oxygen.
2, How it works
Through the submersible pump, the static water flows through the nozzle to form high-speed water flow, and negative pressure air is formed around the nozzle. After mixing with the water flow through the mixing chamber, the water air mixed flow is generated in the trumpet shaped diffusion management, and the high-speed jet is formed. The water flow with many bubbles is vortex stirred in a large area and depth of water area to complete aeration. The shaft power does not change with the depth of submergence, and the air intake can be adjusted. Therefore, the submerged jet aerator can be used in the pool with large water level change.

QSB-Submerged jet aerator
0.75-Motor power
4, Product features
The aerator is composed of submersible motor and jet pump, so that water agitation and oxygenation can be carried out simultaneously. It has the advantages of high oxygen absorption rate and non clogging impeller Strong unidirectional liquid flow forms effective convection circulation. And the motor load has little influence with the change of water, so it is easy to install.

installation diagram:
7.Main materialThe special pump base and pump shell are cast with HT250 cast iron, which has certain corrosion resistance and can withstand the impact of a certain load.
The motor shaft of the special aeration pump is made of 2cr133214 corrosion-resistant material, and the measures to eliminate stress concentration are taken in the structural design.
The mechanical seal of the special aeration pump can be made of silicon carbide / silicon carbide, tungsten carbide / tungsten carbide and silicon carbide / tungsten carbide according to the pumping medium,
The design service life of mechanical seal is more than 12000 hours.
The bearings of the special aeration pump are imported NSK Bearings, and their cumulative design service life can be guaranteed to be more than 40000 hours.
The static seal of submersible jet aerator adopts butyl qing-700 ring.
All fasteners of submersible jet aerator are made of stainless steel.
The intake pipe of submersible jet aerator is made of galvanized material.
The nozzle is made of cast iron.
8.quality assuranceAfter each submersible jet aerator is assembled, the performance test shall be carried out to ensure that the overall performance of the unit meets relevant standards, the first trouble free operation time shall not be less than 8000 hours, and the design service life of the unit shall not be less than 15 years.
The advantages of jet aerator for air flotation process of mining equipment are as follows:1. It has the advantages of simple installation and low cost. It can be adjusted at any time after installation (mobile installation system can be installed with water). It is suitable for all kinds of small-scale stage aeration needs.
2. Convenient maintenance, self coupling fixed installation, and the main pump can be replaced and repaired at any time without affecting the production process.
3. The failure rate is low. The main pump is a special non clogging sewage pump. The product is mature and the failure rate is very low.
4. Structural advantages: the diving depth can reach 10m, and the motor load changes little with the water level. It is suitable for pools with large water level changes.
5. Aeration has the function of stirring and is suitable for the treatment of high concentration organic wastewater.
6. Diving aeration, uniform aeration, suitable for aeration in a pool with a certain depth.
Difference between centrifugal aerator and jet submersible aerator:First of all, both are submersible aerators, and the air inlet principle is basically the same. Compared with jet aerator, centrifugal aerator has more water outlets, which is better than jet aerator in coverage area and aeration effect. Generally, jet aerator has only one water outlet. The direction of push flow is relatively strong, and the effect of push flow mixing will be better. It is often used in fish, shrimp and crab ponds as aquaculture oxygenation equipment. Centrifugal aerator also has similar extension equipment, which can be connected with external air inlet equipment to increase air intake.
