Ultrasonic cleaning machine transducer common failures

Ultrasonic cleaning machine transducer is made of piezoelectric ceramic material core type transducer, as ultrasonic cleaning machine “two tools” one, the transducer is extremely important. In the specific actual operation, the transducer will produce a variety of failures, the crown Boshi next on its prone to failure of a summary.

1、Ultrasonic transducer moisture

Generally use megohm meter to check and the plug connected to the transducer, check the insulation resistance value between the positive and negative poles of the transducer can be judged. General requirements of insulation resistance greater than 30 megohms or more. If the insulation resistance value is not reached, it is likely that the transducer moisture.

Maintenance method is to put the transducer as a whole (excluding the sprayed shell) into the oven set at about 100 ℃, drying for three hours or use the hair dryer to damp to normal resistance value.

2、transducer oscillator fire, ceramic materials broken

Transducer oscillator fire, ceramic material cracking. Maintenance can be combined with the naked eye and megohmmeter check. Generally as a measure of emergency treatment, you can disconnect the individual damaged transducer, will not affect the normal use of other transducers.

3、transducer deglue

We know that most manufacturers use the glued way to fix the transducer, but the long-term use of ultrasonic cleaning machine due to vibration will appear deglued phenomenon. There are also manufacturers use gluing and screw fastening way, in general, there will be no degluing, due to the role of the screw, the vibrator will not fall from the vibration surface after degluing, the general method of judgment is to lightly shake the tail of the vibrator by hand, carefully observe the vibration surface of the glue situation to make a judgment.

Generally the vibrator degumming after the ultrasonic power output power is normal, but due to the vibrator and vibration surface is not well connected, the vibration surface vibration effect is not good, after a long time because the energy can not be released, it is likely to burn the vibrator.

Vibrator degumming is more troublesome for the user to repair, in general, can only be sent back to the manufacturer for maintenance treatment. Avoid the effective way to avoid the vibrator degumming is usually used to pay attention to not hit the vibration surface.

4、Vibration surface perforation

General ultrasonic transducer full load after several years of use may appear vibration surface perforation, which is due to the vibration surface of the stainless steel plate for a long time high-frequency vibration fatigue, vibration surface perforation indicates that the service life of the transducer has arrived, the maintenance can only be replaced.
