Three Normal Failure Analysis for Ultrasonic Transducer
With the use of ultrasonic transducer extended, the transducer will be more or less some fault problems, the following technicians to explain to you some of the more common ultrasonic transducer failures and solutions:
1, ultrasonic vibrator damp. Megger can be used to check the transducer connected to the plug, check the insulation resistance can determine the basic situation, the general requirements of insulation resistance greater than 5 megohms. If this insulation resistance value is not reached, it is generally the transducer damp, you can put the whole transducer (excluding the plastic shell) into the oven set at about 100 ℃ drying 3 hours or use the hair dryer to the resistance Normal so far.
2, ultrasonic transducer vibrator ignition, ceramic material fragmentation can be combined with the naked eye and the megger to check, generally as a measure of emergency response, you can break the individual damaged oscillator, will not affect the normal use of other oscillator .
3, ultrasonic transducer oscillator degumming. General transducer is the use of cementation, screw fastening double guarantee process, in general, this will not happen, because of the role of screws, vibrator after degumming will not fall from the vibration surface, the general method of judging is to hand shake Oscillator tail, carefully observe the vibration surface of the glue to make judgments. Generally, the power of the ultrasonic power output after the general vibrator degumming is normal, but the vibration effect of the vibrating surface is not good due to the poor connection between the vibrator and the vibrating surface, and the vibrator may be burned after a long time. Dipper degumming treatment is more troublesome, the general situation can only be sent back to the manufacturer to solve. The most effective way to avoid vibrator degumming is not to hit the vibrating surface during normal use.
The above is the ultrasonic transducer several common faults and solutions, we can use the specific view ultrasonic transducer has the above problems!
