The troubleshooting method of sewage mixer involves many aspects, the following are some common faults and their troubleshooting methods:

First, vibration or sway

Cause of failure:

Inundation is not deep enough, forming whirlpools, sucking in air.

The pool capacity is small and the mixing is too violent, resulting in unbalanced impeller.

The guide rod support foundation is loose.

Multiple devices interfere with each other.

The impeller is damaged.

Elimination method:

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.

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

Replace the damaged impeller.

Second, the load current is too large

Cause of failure:

The liquid has a strong viscosity or concentration.

Wrong rotation direction.

The impeller is blocked.

The guide hood interferes with the impeller.

Elimination method:

Choose more powerful equipment to adapt to high viscosity or high concentration of liquids.

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

Remove the debris on the impeller and keep the impeller clean.

Adjust the clearance between impeller and fairing to avoid interference.

Third, abnormal noise

Cause of failure:

The guide hood interferes with the impeller.

The bearing is damaged.

Elimination method:

Adjust the clearance between impeller and fairing to eliminate interference.

Replace the damaged bearing and ensure that the bearing is working properly.

Fourth, stator overtemperature alarm

Cause of failure:

The load current is too large.

Electronic overtemperature alarm is damaged.

The motor is damaged.

Elimination method:

Check the load current to eliminate factors that cause excessive current (such as high liquid viscosity, wrong rotation direction, etc.).

Replace the damaged electronic overtemperature alarm device.

Check the motor performance. If the motor is seriously damaged, replace the motor.

Fifth, oil chamber leakage alarm

Elimination method:

Stop the machine immediately, change the oil, and observe if the leakage continues.

If the problem persists after the oil change, check whether the mechanical seal is damaged and replace the mechanical seal if necessary.

Sixth, other general troubleshooting methods

Check the power supply:

Ensure that the power supply voltage is stable and the plug is not loose or corroded.

Check if the fuse is burned out and replace it if necessary.

Check the electrical system:

Check whether the electrical wiring and wiring are normal, and check whether the electrical components are operating normally.

If electrical system failure is found, repair or replace damaged parts in time.

Regular maintenance:

Regular maintenance of the mixer, including blade cleaning, check bearing lubrication, etc.

Keep equipment clean and dry to prevent corrosion and clogging.

Replacement of damaged parts:

If the key parts of the mixer (such as motors, bearings, seals, etc.) are found to be seriously damaged, they should be replaced in time to ensure the normal operation of the equipment.

Compliance with operating procedures:

Operators should be familiar with the use of the equipment and operating procedures, according to the requirements of the correct operation of the equipment.

Avoid device faults caused by misoperation and overload.

Through the above method, the common faults of the sewage mixer can be effectively eliminated, to ensure the normal operation of the equipment and extend the service life. At the same time, regular maintenance and maintenance is also an important measure to prevent failure.
