1. Failure of dye circulation system
Circulation pump failure
Performance: circulation pump does not work, loud noise, insufficient flow, etc.
Cause: It may be motor damage, impeller blockage, seal damage, etc.
Solution: Check whether the motor is running normally, clean the impeller blockage, and replace the seal.
Pipeline blockage
Performance: poor dye flow and abnormal pressure.
Cause: accumulation of dye or impurities in the pipeline, bending or deformation of the pipeline, etc.
Solution: flush the pipeline with a cleaning agent to remove the blockage; check whether the pipeline is bent or deformed, and repair or replace it.
Valve failure
Performance: valve cannot be opened or closed, poor sealing, etc.
Cause: valve damage, valve core stuck, seal aging, etc.
Solution: replace valve, clean valve core, replace seal.
2. Temperature control system failure
Heating element failure
Performance: unable to heat, uneven heating, too high or too low temperature, etc.
Cause: heating element damage, thermostat failure, sensor failure, etc.
Solution: Replace the heating element, check the thermostat and sensor, and repair or replace them.
Temperature sensor failure
Performance: inaccurate temperature display, large temperature fluctuations, etc.
Cause: sensor damage, poor contact, interference, etc.
Solution: Replace the sensor, check the connection line, and eliminate the interference source.
3. Electrical system failure
Motor failure
Performance: motor does not work, loud noise, severe heating, etc.
Cause: motor damage, power failure, overload protection, etc.
Solution: Check the motor and power supply, troubleshoot; check the overload protection device, and adjust the load.
Control system failure
Performance: no display on the control panel, button failure, program error, etc.
Cause: controller damage, software failure, power supply interference, etc.
Solution: replace the controller, reinstall the software, and eliminate the interference source.
4. Mechanical structure failure
Seal damage
Performance: dye leakage, pressure drop, etc.
Cause: seal aging, improper installation, damage by external force, etc.
Solution: replace the seal, install the seal correctly, and avoid external damage.
Agitator failure
Performance: uneven stirring, loud noise, bending of stirring shaft, etc.
Cause: damaged agitator, deformed agitator shaft, transmission failure, etc.
Solution: replace agitator, repair agitator shaft, check transmission.
5. Other failures
Dyeing tank corrosion
Performance: corrosion and rust on the inner wall of the dyeing tank, etc.
Cause: chemical properties of dyeing liquid, long-term use, incomplete cleaning, etc.
Solution: choose corrosion-resistant dyeing tank materials, clean the dyeing tank regularly, add corrosion inhibitors.
Uneven color
Performance: uneven color and color difference of dyed samples, etc.
Cause: poor circulation of dyeing liquid, uneven temperature, uneven distribution of dyes, etc.
Solution: check the dyeing liquid circulation system, adjust the temperature, and optimize the dyeing process.
