The ultrasonic transducer is damp. In general, Megabyte meter is used to check the plug connected with the transducer. The insulation resistance value between the positive and negative terminals of the transducer can be determined.
Ultrasonic cleaner transducer often appear problems
1) The ultrasonic transducer is damp. In general, Megabyte meter is used to check the plug connected with the transducer. The insulation resistance value between the positive and negative terminals of the transducer can be determined. General requirements of insulation resistance greater than 30 megohm. If this insulation resistance is not achieved, it is likely that the transducer will become damp. The maintenance method is to put the transducer as a whole (excluding the plastic shell) into the oven and set it at about 100℃, dry it for three hours or use the hair dryer to remove the moisture until the resistance is normal.
2) The transducer vibrator burns and the ceramic material breaks. Maintenance can be combined with the naked eye and megohm meter inspection. Generally, as an emergency treatment measure, the individual damaged transducer can be disconnected, which will not affect the normal use of other transducers.
3) The transducer is degummed. We know that most manufacturers use a sticky way to fix the transducer, but the long-term use of the ultrasonic cleaning machine due to vibration will appear degumming phenomenon. Some manufacturers also use the method of cementing and screw fastening, generally there will be no degumming, because of the action of the screw, the oscillator will not fall from the vibration surface after degumming, the general judgment method is to use the hand to shake the tail of the oscillator, carefully observe the glue on the vibration surface to make a judgment.
Generally, the output power of the ultrasonic power supply is normal after the oscillator is degumed. However, due to the poor connection between the oscillator and the vibration surface, the vibration effect of the vibration surface is not good. After a long time, due to the energy cannot be released, it is likely to burn out the oscillator. It is troublesome for the user to repair the vibrator. In general, it can only be returned to the manufacturer for maintenance. The most effective way to avoid degumming is to pay attention not to hit the vibration surface in normal use.
4) Vibration surface perforation. In general, the vibration surface may be perforated after the ultrasonic transducer is used at full load for several years, which is due to the long length of the stainless steel plate on the vibration surface
Due to fatigue caused by high frequency vibration, the vibration surface perforation indicates that the service life of the transducer has arrived, and the maintenance can only be replaced generally.
Ultrasonic cleaner generator often appear problems
1) Turn on the power switch of the ultrasonic cleaner, and the indicator light is not on. In this case, the maintenance must check whether the power switch is in good condition and whether the leakage switch is closed. If the switch is in good condition, then check whether the fuse is overloaded and fuse is broken.
2) When the power switch is turned on, the indicator light is on, but there is no ultrasonic output. This kind of circumstance is more complex, when maintenance, check the connection plug of transducer and ultrasonic power board whether to have loosen first, check whether fuse is blown next. If everything is normal, it may be the internal fault of the ultrasonic power generator. Use the multimeter to make the open power line and the fire line. After the generator fault is eliminated, check whether the ultrasonic transducer is burnt out and whether it needs to be replaced.
3) The dc fuse of the ultrasonic cleaner is blown. It may be the burn out of the rectifier bridge stack or the power tube, or the aging of the transducer and the instability of the current, which may cause the failure of the power generator. Take care when repairing.
4) After turning on the power switch of the ultrasonic cleaner, the machine has ultrasonic output, but the cleaning effect is not as good as before. This situation is mostly caused by improper use, for example, the cleaning liquid level in the cleaning tank is improper, too high or too low; Ultrasonic frequency coordination is not adjusted; The liquid temperature in the cleaning tank is too high or too low; Improper use of cleaning liquid or insufficient dosage. Of course, it is not ruled out that most of the ultrasonic energy cannot be transferred to the cleaning fluid after the transducer is degummed-this situation should be sent back to the manufacturer in time for maintenance, so as not to burn out the oscillator.
Of course, the above is just some basic maintenance ideas of ultrasonic cleaning machine, in the actual maintenance operation also need to be rich in professional knowledge and practical experience, ultrasonic cleaning machine now the general service life can be used basically five to eight years above.
