common problems of Ultrasonic cleaning equipment transducer

1. The piezoelectric cleaning transducer is damp. Generally, the megohmmeter is used to check the plug connected to the transducer, and the insulation resistance between the positive and negative poles of the transducer can be checked. Insulation resistance is generally required to be greater than 30 megohms. If this insulation resistance value is not reached, it is likely that the transducer is damp. The maintenance method is to put the whole transducer (excluding the sprayed plastic case) into the oven setting to about 100 degrees, dry for three hours or use a hair dryer to remove the tide until the resistance is normal. The transducer vibrator is ignited and the ceramic material is broken. The inspection can be combined with the naked eye and the megohmmeter during maintenance. Generally, as an emergency treatment measure, individual damaged transducers can be disconnected without affecting the normal use of other transducers.

2. The transducer is degummed. We know that most manufacturers use adhesive to fix the transducer. However, after long-term use of the ultrasonic cleaning device and due to the action of the screw, the vibrator will not fall off the vibrating surface after degumming. The general method of judging is to gently shake the vibrator by hand. At the tail, carefully observe the glue on the vibrating surface to make a judgment.

3. After the detonation of the general vibrator, the output power of the piezoelectric ultrasonic cleaning transducer supply is normal. However, since the vibrator and the vibrator surface are not well connected, the vibration surface vibration effect is not good. After a long time, the energy cannot be released, and the vibrator may be burned out. The vibrator degumming is more troublesome for the user to repair, and the general situation can only be sent back to the manufacturer for maintenance. The most effective way to avoid degumming of the vibrator is to pay attention to not hit the vibrating surface during normal use.

Perforation of the vibrating surface. Generally, the industrial ultra bath transducer may be perforated on the vibrating surface after being used for a full load for several years. This is due to the high-frequency vibration fatigue of the vibrating surface of the stainless steel plate for a long time. The perforation of the vibrating surface indicates that the service life of the transducer has arrived. Repairers can only be replaced.
