The troubleshooting method of sewage mixer mainly includes the following aspects:

　　First, the elimination method for specific fault phenomena

　　Vibrate or sway

　　Reasons: Inundation depth is not enough, pool capacity is small, resulting in too strong mixing, guide rod support installation foundation is loose, multiple devices interfere with each other, impeller damage, etc.

　　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.

　　Excessive load current

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

　　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.

　　Abnormal noise

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

　　Elimination method:

　　Adjust the clearance between impeller and fairing to eliminate interference.

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

　　Stator overtemperature alarm

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

　　Elimination method:

　　Check the load current to eliminate factors that cause excessive current.

　　Replace the damaged electronic overtemperature alarm device.

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

　　Oil chamber leak 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.

　　Second, general troubleshooting methods

　　Check 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 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.

　　Replace 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.

　　Follow the operating rules

　　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.

　　Third, preventive measures

　　Reasonable selection: According to the nature of the treated sewage, the size of the tank, mixing needs and other factors, choose the appropriate sewage mixer model and power.

　　Correct installation: Install in strict accordance with the equipment instructions to ensure that the installation position, depth and Angle of the mixer meet the design requirements.

　　Professional training: Provides professional training to operators to improve their operation skills and troubleshooting capabilities.

　　By taking the above elimination methods and preventive measures, the fault problem of the sewage mixer can be effectively solved to ensure the normal operation of the equipment and extend the service life.
