Product Introduction:
The QSP submersible jet underwater aerator is mainly composed of a submersible electric pump, a Venturi tube, a diffuser tube, an intake pipe, and a muffler. The installation forms of QSB jet type underwater aerator are divided into two types: mobile and self coupling. The mobile installation method is to install the underwater aerator at the bottom of the pool, relying on self weight positioning, and has the characteristics of adjustable installation position, flexibility, and low cost. Self coupling installation is to fix the aeration device and a dedicated base at the bottom of the water tank, install supporting blocks on the top of the tank, and connect the two with guide rails. After the submersible pump is connected to a specific bracket, it slides down along the guide rail to the outlet position of the base. Through the self weight of the pump, it automatically couples and seals. Self coupling installation allows for the lifting and installation of electric pumps without the need for installation or maintenance personnel to enter the water tank.
Scope of application:
Suitable for deep water aeration, aeration and agitation in biochemical tanks, sludge aeration and agitation, and high concentration organic wastewater treatment processes. The QSB jet type underwater aerator can operate continuously under the following conditions: 1. The high medium temperature does not exceed 40 ℃; 2. The pH value of the medium is between 5 and 9; 3. The medium density shall not exceed 1150kg/m3.
The water flow generated by the submersible pump passes through the nozzle to form a high-speed water flow, which creates negative pressure around the nozzle. The air is sucked in by the intake pipe and mixed with the water flow through the mixing chamber. A water gas mixture flow is generated in the trumpet shaped diffusion pipe, which is sprayed out at high speed. The water flow carrying many bubbles vortices and stirs in a large area and depth of water, completing aeration. The shaft power does not change with the depth of the submersible, and the intake air volume can be adjusted. Therefore, jet aerators can be applied in pools with significant changes in water level.
Product features:
The QSP submersible jet type underwater aerator consists of a submersible electric pump and a spray port, which enables simultaneous agitation and oxygenation of the water body. The bubbles are fine, which can achieve a high oxygen transfer rate and has the advantages of unobstructed impeller. Strong unidirectional liquid flow creates effective convective circulation, and the motor load changes very little with the water level. It is easy to install, low-cost, and easy to maintain.

Centrifugal underwater aerator
Product Introduction: The motor directly drives the impeller to rotate at high speed, forming a negative pressure zone around the high-speed rotating impeller, thereby generating self suction force. A large amount of fresh air is sucked into the guide groove through the suction pipe and fully mixed with the sewage in the groove, producing a large number of ultra-fine bubbles, which cause high oxygen movement and thus obtain oxygen dissolution rate.
The structure of the QXB centrifugal underwater aerator is a direct coupled, self-priming aerator. The centrifugal force generated by the rotating impeller forms negative pressure at the inlet of the impeller to suck in air and water. The kinetic energy of the impeller is used to mix a certain proportion of air and water in the mixing chamber. Under strong centrifugal force, the two-phase flow of air and water is rectified along the tangential direction of the impeller through the flow channel, and then diffuses in the circumferential direction. The fine tiny bubbles are fully fused with water, thus achieving the effect of oxygenation aeration.
Scope of application:
QXB centrifugal underwater aerator is suitable for aeration tanks, aeration sedimentation tanks, pre aeration tanks, aerobic nitrification tanks, aeration and oxygenation mixing in various sewage biochemical treatment processes, as well as oxygenation in aquaculture ponds.
Product features:
1. Self weight positioning, easy installation, and can be freely arranged without interrupting process operation;
2. Compact design structure, utilizing self-priming function without the need for external air source;
3. The diving operation of the host reduces the footprint and produces low noise;
4. It can be directly used in the oxidation pond, saving infrastructure costs;
5. An independently movable aeration device can also be used as a mixer (note: when the air inlet is closed);
6. The chassis can be specially designed according to user requirements.
