Jet Submerged Aerator Models and Product Features
The aeration machine is composed of a submersible pump and a jet pump, allowing water stirring and aeration to occur simultaneously. This design not only achieves a high oxygen absorption rate but also boasts the advantage of wheel blockage-free operation.
Robust unidirectional fluid flow generates an effective convection cycle, with minimal motor load variation with water level, and easy installation.

Jiangsu Du'an Environmental Protection QSB3.0 Jet Submerged Aeration Model Cautionary Notes
1、 Do not lift cables directly or use cables to lift other heavy objects during equipment hoisting. When transporting or suspending submersible aeration units, use a chain with a hook to attach to the lugs or吊环 on the top cover.
2、 Cable ends must not be immersed in water.
3、 All equipment enclosures should be reliably grounded to prevent electric shock accidents.
4、 Due to the working principle, the immersion depth should not exceed the specified limit.
5The submersible aeration pump should not be placed at the wastewater intake. When the base is placed on muddy ground or floating sand, the submersible aeration pump may sink due to vibration. In such cases, it is recommended to suspend the aeration pump or place it on a larger base plate.
6When temperatures drop to0Below 0°C, if the潜水曝气机continues to operate normally, it may be used as usual; otherwise, it should be lifted.
Store in a well-ventilated, dry area and prevent freezing.
Submersible Jet Aerator Maintenance and Inspection
Fault Phenomenon | Original Content | Clearing Method |
Power equipment overloading | The incoming water pool does not meet the requirements. Leaf blades of the 2-submerged aeration machine are wrapped with debris. 3 Submersible Aerator Blades Rubbing Against Guide Vanes The speed of the 4-submersible aeration pump exceeds the specified value. | Enhanced Water Inflow Conditions Clear away debris; wash with water. Inspect blade wear and realign installation. Adjusted the original motor to meet the rated speed. |
Reduced aeration or no aeration | The submerged depth of the water aeration machine is too deep. 2 Blade outer circumference wear, or partial blade damage Divers' aeration转向 was incorrect The four-blade impeller has come loose. 5 Submersible Aerator Has Impurity Clogging | Enhance Diving Aeration Machines 2 Replaced Impeller 3 Reverse Rotation Direction 4 Fasteners Clear away debris, use water to clean |
Operational noise or vibration
| The foundation of the submersible aeration pump is not sufficiently solid or the nuts are loose. 2 Blade and guide vanes experiencing friction Loose three-blade impeller screws or partial blade damage 4 Inlet Water Condition Unstable 5潜水 aeration pump has impurities clogging | Strengthen foundations, tighten bolts 2. Inspect the gap between the impeller and guide vanes Tighten screws or replace impellers 4 Adjust Water Inflow Status Clear away debris, wash with water. |
Diving aeration pumps fail to start or fuses blow | 1 Winding, joint, or cable interruption 2 Submersible Aeration Pumps Clog 3 Leaking or Short Circuit No Chinese content provided. | Check with an ohmmeter Turn off power and clear debris Insulation checks failed; readings were below the required level. Drying is mandatory. Post-inspection and maintenance use |
The circuit breaker and overload protector of the submersible aeration pump tripped after startup. | Low Voltage 2 High Voltage Incorrect motor wiring or mixed terminals Electrical Fault in Control Cabinet | 1. Do not use temporarily or add emphasis to the power line if voltage drop is caused by excessive length. Install transformers and adjust the voltage to the specified level. Revised Wiring and Connectors Inspect and replace electrical components |
Equipped with stainless steel field control cabinets for installation and use.
