The ultrasonic cleaning equipment mainly consists of an ultrasonic generator and an ultrasonic transducer. The ultrasonic transducer is a core-type transducer made of lead zirconate titanate piezoelectric ceramic material. Piezoelectric ceramic material has the phenomenon of dimensional change under the action of an electric field. Under the action of an alternating electric field, the transducer will generate mechanical vibration.
If the ultrasonic transducer gets damp, a megohmmeter can be used to check the plug connected to the transducer. Pin 2 is the positive pole of the ultrasonic transducer, and pin 3 is the negative pole of the transducer and is connected to the transducer's housing. Check the insulation resistance value between pins 23 to determine the basic situation. Generally, the insulation resistance should be greater than 30 megohms. If the insulation resistance value cannot be reached, it is generally because the transducer is damp. You can put the entire transducer into an oven set at around 100℃ for drying for 3 hours or use a hair dryer to remove the moisture until the resistance value returns to normal. If the transducer oscillator sparks and the ceramic material breaks, it can be inspected by combining the naked eye and a megohmmeter. Ultrasonic cleaning equipment is generally used as an emergency measure, which can disconnect individual damaged oscillators without affecting the normal use of other oscillators. The vibrator has come off the adhesive. Our transducer adopts a dual guarantee process of bonding and screw fastening. Under normal circumstances, this situation will not occur. Due to the effect of the screws, the vibrator will not fall off the vibrating surface after delamination. The general method of judgment is to gently shake the tail of the vibrator with your hand and carefully observe the adhesive condition on the vibrating surface to make a judgment. Generally, after the vibrator experiences delamination, the output power of the ultrasonic power supply remains normal. However, due to poor connection between the vibrator and the vibration surface, the vibration effect of the vibration surface is not good. Over time, the vibrator may be burned out. The treatment method for the delamination of the oscillator is rather troublesome. Generally, it can only be sent back to the manufacturer for resolution. An effective way to prevent the vibrator from delaminating is to be careful not to strike the vibrating surface during normal use. Perforation of the vibration surface may occur in ultrasonic cleaning machines after the transducers have been in full-load operation for several years.
