(1) The ultrasonic transducer is damp. Generally, the megohmmeter is used to check the plug connected to the transducer, and the insulation resistance between the positive and negative poles of the transducer can be checked. Insulation resistance is generally required to be greater than 30 megohms. If this insulation resistance value is not reached, it is likely that the transducer is wet. The maintenance method is to put the whole transducer (excluding the sprayed plastic case) into the oven setting to about 100 °C, dry for three hours or use a hair dryer to remove moisture until the resistance is normal. The transducer vibrator is fired and the ceramic material is broken. The inspection can be combined with the naked eye and the megohmmeter during maintenance. Generally, as an emergency treatment measure, individual damaged transducers can be disconnected without affecting the normal use of other transducers. (2) The transducer is degummed. We know that most manufacturers use adhesive to fix the transducer, but the ultrasonic cleaner will degumming due to vibration after long-term use. There are also manufacturers that use the method of fastening with screws and screws. Under normal circumstances, there will be no degumming. Due to the action of the screws, the vibrator will not fall off the vibrating surface after degumming. The general judgment method is to gently shake the tail of the vibrator by hand and observe the vibration carefully. The judgment of the glue condition of the face. (1) The ultrasonic cleaner turns on the power switch, and the indicator light does not light. In this case, you must check whether the power switch is intact and the leakage switch is closed. If the switch is intact and then check if the fuse is overloaded and blown, it can basically be solved. (4) After the ultrasonic cleaning machine turns on the power switch, 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; the ultrasonic frequency coordination is not adjusted well; the liquid temperature in the cleaning tank is too high or too low; the cleaning liquid is improperly used or used. not enough. Of course, it is not excluded that most of the ultrasonic energy cannot be transmitted to the cleaning liquid after the degumming of the transducer. This situation should be sent back to the manufacturer for repair in time to avoid burning the vibrator.

(3) After the detonation of the general vibrator, the output power of the ultrasonic power supply is normal, but since the vibrator is not well connected to the vibrating surface, the vibrating surface has a bad vibration effect, and the energy may not be released after a long time, and the vibrator may be burned out. The degumming of the vibrator is troublesome for the user to repair, and the general situation can only be sent back to the manufacturer for maintenance. The most effective way to avoid degumming of the vibrator is to pay attention to not hit the vibrating surface during normal use.
(4) Perforation of the vibrating surface. Generally, the ultrasonic transducer may be perforated on the vibrating surface after being used for a full load for several years. This is due to the high-frequency vibration fatigue of the stainless steel plate on the vibrating surface for a long time. The perforation of the vibrating surface indicates that the service life of the transducer has arrived. Maintenance can only be replaced.
Common problems with ultrasonic cleaner generators are:
(2) After the ultrasonic cleaner turns on the power switch, the indicator light is on, but there is no ultrasonic output. This situation is more complicated. When repairing, first check if the connection plug of the transducer and the ultrasonic power board is loose, and then check if the fuse is blown. If everything is normal, it may be an internal fault of the ultrasonic power generator. Use a multimeter to open the power line and the fire line is open. Check if the ultrasonic transducer is burnt out after the generator failure is removed and it needs to be replaced.
(3) The DC fuse of the ultrasonic cleaner is blown. It may be that the rectifier bridge or power tube is burnt, or the transducer is aging and the current is unstable, which may cause the power generator to malfunction. Pay more attention when repairing.
