The troubleshooting method of sewage mixer involves many aspects, mainly including mechanical failure, electrical failure and failure caused by operational and environmental factors. Here are some common troubleshooting methods:

First, mechanical troubleshooting methods

Vibrate or sway

Causes: inundation depth is not enough, pool capacity is small, impeller imbalance, guide rod support installation foundation is loose, multiple devices interfere with each other, impeller damage, etc.

The solution:

Increase the submerge depth and make sure the blender is fully submerged.

Choose equipment suitable for the pool volume to avoid mixing too violently.

Reinforce the guide rod to support the installation foundation to ensure stability.

Increase device spacing or set up anti-interference board to reduce mutual interference between devices.

Inspect and replace the damaged impeller.

Excessive load current

Reasons: strong viscosity or high concentration of liquid, wrong direction of rotation, impeller obstruction, guide hood and impeller interference.

The solution:

Choose high-power equipment to adapt to high viscosity or high concentration of liquids.

Check and adjust the rotation direction to make sure it is correct.

Remove the debris on the impeller and keep it smooth.

Adjust the clearance between impeller and fairing to avoid interference.

Abnormal noise

Reasons: the guide hood and impeller interference, bearing damage, etc.

The solution:

Adjust the clearance between impeller and fairing to ensure no interference.

Inspect and replace damaged bearings.

Bearing failure

Reasons: long running, insufficient lubrication, foreign body intrusion and so on.

The solution:

Clean bearings regularly and replace lubricating oil to maintain good lubrication.

Check whether the bearing is worn or damaged, and replace it in time.

Second, electrical troubleshooting methods

Motor does not respond or does not start

Cause: power line failure, motor damp or water, fuse blown, etc.

The solution:

Check whether the power cable is in good contact, and reconnect or replace the damaged cable.

Ensure that the motor is dry without moisture, and dry it if necessary.

Check and replace blown fuses.

Stator overtemperature alarm

Cause: the load current is too large, the electronic overtemperature alarm device is damaged, the motor is damaged, etc.

The solution:

Check the load situation and reduce the load appropriately, or choose more powerful equipment.

Replace the damaged electronic overtemperature alarm device.

Check motor performance and repair or replace it if necessary.

Third, troubleshooting methods caused by operational and environmental factors

Poor mixing effect

Reasons: the mixing speed is set improperly, there are dead corners in the mixing tank, etc.

The solution:

Adjust the mixing speed to the appropriate range to ensure the mixing effect.

Optimize the mixing tank design, eliminate the dead Angle, improve the mixing efficiency.

Equipment clogging

Reason: The stirring medium contains a large number of solid particles or fiber materials.

The solution:

Clean the blender and its surrounding area regularly to prevent debris buildup.

Optimize blender design to reduce clogging risk.

Fourth, comprehensive troubleshooting suggestions

Regular inspection and maintenance: Regular inspection and maintenance of the sewage mixer, including the mechanical part, the electrical part and the operating environment. Discover and handle potential faults in a timely manner.

Train operators: Train operators on equipment operation and maintenance to improve operation skills and emergency handling capabilities.

Establish fault recording and analysis system: record and analyze every fault, summarize experience and lessons, and constantly improve troubleshooting methods and preventive measures.

Through the above methods,

Nanjing LanJiang Water Treatment Equipment Co.,Ltd manufactures equipment for wastewater treatment. We were established in 2001. Since then, we designed and produced submersible mixers, top entry mixers, aerators and other wastewater treatment equipment.
