The maintenance of ultrasonic cleaning machines should start from three aspects: daily operation, regular inspection, and fault prevention. The specific methods are as follows:
1、 Daily operation standards
1. Cleaning solution management
Choose neutral or weakly alkaline cleaning agents to avoid corrosion of equipment by strong acid and alkali liquids.
Thoroughly drain any residual liquid after each use to prevent sedimentation from clogging the transducer or pipeline. It is recommended to replace the cleaning solution once a week.
The liquid level should cover the cleaned item and not exceed the maximum capacity. It is strictly prohibited to start without liquid.
2. Equipment cleaning
After use, wipe the groove and body with a soft cloth in a timely manner, keep it ventilated and dry, and prevent the circuit from getting damp or the metal parts from rusting.
Regularly clean the dirt at the bottom of the tank to avoid impurities affecting the transmission of ultrasonic waves.
2、 Key points for regular maintenance
1. Electrical inspection
Use a megohmmeter to test the insulation resistance of the transducer every month (>30 megohms required), and if it is found to be damp, it needs to be dried.
Check the power cord, plug, and grounding device to avoid aging or poor contact.
2. Component maintenance
Check the fit between the transducer and the slot body. If there is detachment or perforation on the vibrating surface, it needs to be returned to the factory for repair.
Industrial equipment should avoid overload operation and control the single cleaning time (3-10 minutes) and temperature (≤ 60 ℃).
3、 Common fault prevention
1. Poor cleaning effect: Adjust the frequency (high frequency for precision parts, low frequency for heavy workpieces) and disperse the workpieces.
2. No ultrasonic output: Check the connection of the transducer, fuse, and control board status.
3. Abnormal noise: Ensure that the equipment is placed horizontally and replace worn shock absorbers.
4. Seasonal maintenance suggestion: Increase dehumidification during the rainy season and preheat the cleaning solution to above 20 ℃ before starting in winter.
