Repair and maintenance of ultrasonic cleaning machine

   Repair and maintenance of ultrasonic cleaning machine

Ultrasonic cleaning machine is mainly composed of ultrasonic generator and ultrasonic transducer, ultrasonic cleaning machine is made of lead zirconate titanate piezoelectric ceramic material sandwich type transducer, piezoelectric ceramic material has the phenomenon of size change under the action of electric field, the transducer will produce mechanical vibration under the action of alternating electric field.

Ultrasonic transducer common problems.

1, ultrasonic vibrator moisture, you can use megohmmeter to check the plug connected to the transducer, where 2 feet for the positive pole of the ultrasonic transducer, 3 feet is the negative pole of the transducer and connected to the shell of the transducer. Check, 23 feet between the insulation resistance value can determine the basic situation, the general requirements of insulation resistance greater than 30 megohms or more. If you can not reach this insulation resistance value, generally the transducer moisture, you can put the transducer as a whole (excluding the sprayed shell) into the oven set at about 100 ℃ drying 3 hours or use the hair dryer to moisture to normal resistance value.

2, transducer vibrator fire, ceramic material shattered, you can use the naked eye and megohmmeter combination check, generally as a measure of emergency treatment, you can disconnect the individual damaged vibrator, will not affect the normal use of other vibrators.

3, the vibrator debonding, our transducer is the use of gluing, screw fastening double assurance process, in general, this situation will not occur, due to the role of the screw, the vibrator debonding will not fall from the vibration surface, the general method of judgment is to use the hand to lightly shake the tail of the vibrator, carefully observe the vibration surface of the glue situation to make a judgment. Generally, after the shock is deglued ultrasonic power output power is normal, but because the shock and vibration surface is not well connected, the vibration surface vibration effect is not good, after a long time may burn the shock. The treatment of the shock off the glue is relatively troublesome, the general situation can only be sent back to Dongguan ultrasonic cleaning equipment manufacturers to solve. To avoid the most effective way to avoid the shock son degumming is the usual use of attention not to hit the vibration surface.
