Maintenance and troubleshooting methods for jet aerators

Submersible jet aerator

QSB jet aerator

1. Cleaning

To prevent impurities from accumulating inside the submersible aerator at different times, clean water can be pumped from the submersible aerator to clean it. If the submersible aerator is not used for a long time, it should be placed in a dry place and pay attention to antifreeze.

2. Oil injection and oil change

Nanjing Du'anThe oil chamber of the submersible aerator has been injected with an appropriate amount of lubricating oil before leaving the factory. This oil should be replaced annually. The oil change should be carried out according to the following method: place the submersible aerator with the oil chamber plug facing downwards, loosen the plug, release the lubricating oil, then clean the oil chamber with washing oil, inject an appropriate amount of lubricating oil, and replace it with a new oneO-ring, tighten the screw plug. If water is found in the oil, flush the oil chamber according to regulations, refill it with oil, and tighten the screw plug with O-ring. Three weeks later, it must be rechecked. If the oil turns into an emulsion again, the mechanical seals should be inspected. If necessary, it should be replaced (please contact our maintenance department).

pourThe oil is transformer oil.

3. Operational malfunction

In case of a malfunction during operation, if the cause cannot be determined and the troubleshooting methods provided later still cannot solve the problem, temporary methods should not be used, and unauthorized repairs and dismantling should not be carried out. Contact our Nanjing Du'an Water Treatment After sales Service Department immediately.

Troubleshooting method for jet type submersible aerator

Fault phenomenon	cause analysis	Nanjing Du'an Water TreatmentTroubleshooting
power equipment overload	1. The inlet pool does not meet the requirements 2. The blades of the submersible aerator are surrounded by debris 3. The blades and guide vanes of a submersible aerator Friction arises 4. The speed of the submersible aerator exceeds the specified value	1. Improve water inlet conditions 2. Remove debris and clean with water 00001. Check the wear of the blades and readjust the installation dress 4. Adjust the prime mover to meet the rated speed
Decreased aeration rate Less or no exposure gas	1. The diving depth of the submersible aerator is too deep 2. Wear of the outer circle of the impeller blades or blade parts Split damage 3. The diving aerator is turning the wrong direction 4. The impeller is loose 5. The submersible aerator is blocked by impurities	1. Improve the submersible aerator 2. Replace the impeller 3. Correct the rotation direction 4. Tighten the screws 5. Remove debris and use water to clean up
Running with impurities Sound or vibration	1. The foundation of the submersible aerator device is not strong enough Loose screws or nuts 2. Friction occurs between the impeller and guide vanes 3. Loose impeller screws or damaged blade parts 4. Unstable water inflow state 5. The submersible aerator is blocked by impurities	1. Strengthen the foundation and tighten the screws 2. Check the center and gap 3. Tighten the screw or replace the impeller 4. Adjust the water inlet status 5. Remove debris and clean with water
Diving aeration The machine cannot be started Move or fuse circuit breaker	1. Winding, connector or cable open circuit 2. Submersible aerator blockage 3. Leakage or water leakage 4. Short circuit	1. Check with an ohmmeter 2. Cut off the power and remove debris 3. Check the insulation, if it is below the specified value, it must be Perform drying 4. Use after inspection and maintenance
Diving aeration After the machine is started, Circuit breaker passed Carrier disconnected	1. Low voltage 2. High voltage 3. Incorrect motor wiring or confusion of connectors 4. Control cabinet electrical malfunction	1. Not currently in use or due to excessively long wiring Induced voltage drop 2. Install a transformer and adjust the voltage to the specified value 3. Adjust wiring and connectors 4. Check and replace electrical components

Any adjustment of the equipment must be approved by our company!
