1. First check the working surface of the ultrasonic cleaning transducer to make sure that the working surface has not broken down. If the transducer has been removed from the main body of the machine, gently shake the whole of the transducer to see if there is any abnormal sound inside, if it has already penetrated.The ultrasonic transducer vibration cleaning must be repaired with professional techniques.
2. Checking the insulation resistance between the positive and negative poles of the transducer with a megger (the negative pole of the transducer is always connected to the outer casing of the transducer. This is determined by the manufacturing process of the piezoelectric transducer for ultrasonic bonding. The most effective method for wiring, generally requires more than 30 megohms to be normal. For a transducer with a resistance is less than this number, it can still work for a certain period of time under certain conditions, but it is easy to cause generator failure, if there is no megohm on hand. The table can be used with the maximum resistance of the multimeter, but the accuracy of piezoelectric cleaning transducer is a discount.
3. By using the capacitance of meter to test the static capacitance of the transducer, compared with the average value of the same transducer capacitance value, piezo ring piezoelectric transducer can be very sensitive to the problem, the transducer with large capacitance value may enter the water,which become smaller, a malfunction of internal transducer head damage or debonding may occur.
