Troubleshooting and maintenance of ultrasonic cleaning machine

Troubleshooting and maintenance of ultrasonic cleaning machine

One, to judge the failure of ultrasonic cleaning machine

1 ultrasonic cleaning machine to turn on the power switch, the indicator light is not bright, no ultrasonic output. Reason: A. power switch is damaged, there is no power input; B. fuse ACFU fuse.

2 ultrasonic cleaning machine after the power switch is turned on, the indicator light is bright, but there is no ultrasonic output. Reason: A. transducer and ultrasonic power board connection plug loose; B. fuse DCFU fuse; C. ultrasonic power generator fault; D. transducer fault.

3 ultrasonic cleaning machine DC fuse DCFU fuse. Reason: A. rectifier or power tube burning; B. transducer fault.

4 ultrasonic cleaning machine after the power switch is turned on, the machine has ultrasonic output, but the cleaning effect is not ideal. Reason: A. cleaning tank cleaning liquid level is improper; B. ultrasonic frequency coordination is not good; C. cleaning tank liquid temperature is too high or too low; D. cleaning fluid selection is improper; E. ultrasonic generator aging.

Two, ultrasonic cleaning machine maintenance problems

Cleaning system is composed of an ultrasonic generator and an ultrasonic transducer, the ultrasonic transducer is by the pressure of dielectric ceramics manufacturing sandwich type transducer, pressure of piezoelectric materials under the action of alternating electric field will produce mechanical vibration.

Ultrasonic transducer common problems

1 ultrasonic vibrator affected with damp, can be used to check the connection with the transducer of the plug, check the insulation resistance value can determine the basic situation, the general requirements of the insulation resistance is greater than 5 mb. If not up to the value of insulation resistance, damp transducer, the transducer as a whole (not including the shell spray) put into the oven set drying about 100 DEG C for 3 hours or use a hair dryer to normal tide to resistance.

2 transducer ignition, fracture of the ceramic materials can be with the naked eye and megohm table combined examination, generally as emergency treatment measures can disconnect the damage to the individual oscillator, does not affect to the normal use of the other oscillator.

3 oscillator, our transducer is the use of cement, screw fastening double assurance process, in general, this situation will not occur.

4 stainless steel vibrating surface perforation, the general use of the full load of the transducer for 10 years may be the case of vibration surface perforation.
