Core Symptom: Power indicator light is off, no ultrasonic output.
Possible Causes and Solutions:
Power Issue: Check if the power supply is connected and if the switch is damaged.
Blown Fuse: Check and replace the AC (ACFU) or DC (DCFU) fuse.
Internal Connection or Hardware Failure: Check if the connection plug between the transducer and the power board is loose. If the connection is normal, the issue is likely a fault in the ultrasonic generator, transducer, or power tube, which usually requires professional inspection.
Core Symptom: Equipment runs normally, but cleaning/stain removal effect is unsatisfactory.
Possible Causes and Solutions:
Improper Process Parameters: Incorrect cleaning fluid selection, unsuitable temperature, insufficient cleaning time, or non-optimal ultrasonic frequency/power settings will all affect results. Parameters need to be optimized based on your product and the previously discussed type of soil/contaminant.
Operational Issues:
Improper Liquid Level: Liquid level that is too high or too low will weaken the cavitation effect.
Improper Workpiece Placement: Workpieces stacked too tightly or placed directly on the tank bottom will shield the ultrasonic waves. Use a cleaning basket and maintain reasonable spacing.
Cleaning Fluid Degradation: Cleaning fluid aging and contamination severely reduce cleaning ability. It must be regularly replaced or filtered.
Equipment Performance Degradation: After long-term use, the transducer may age or be damaged, leading to insufficient output power.
Core Symptom: Equipment overheating, abnormally increased noise, component damage.
Possible Causes and Solutions:
Overheating: Continuous operation for too long, or cooling/heat dissipation system failure.
Excessive Noise: Component aging, loose mounting, or potentially indicating an internal fault.
Serious Operational Taboos: Strictly prohibit starting the ultrasonic function when the cleaning tank is empty or the liquid level is severely insufficient, as this will instantly damage the transducer. Also, avoid striking the tank bottom with hard objects.
Core Symptom: Heating system is not working or temperature control is inaccurate.
Possible Causes and Solutions: May be due to poor heater power connection, the heater itself being damaged, the temperature control probe being loose, or the temperature controller malfunctioning.
To avoid many problems, please pay attention to the following points in daily operation:
Standardized Operation: Always ensure the tank has sufficient liquid level before starting; place workpieces correctly.
Maintain Cleanliness: Regularly clean the cleaning tank and replace old cleaning fluid.
Stable Environment: Ensure stable power supply for the equipment and place it in a ventilated, dry, and clean location.
For the precision cleaning applications you are concerned with (such as semiconductors, optical devices), special attention is required:
Higher frequency equipment (such as 68kHz and above), while less likely to damage workpieces, is more sensitive to process parameters (such as temperature, cleaning agent purity) and contaminants.
When cleaning performance is poor, you should prioritize suspecting whether the cleaning fluid is contaminated or ineffective, and whether the rinsing water quality and drying process (such as vacuum drying) are up to standard. These are often the critical factors affecting final cleanliness.
