Repair and maintenance of ultrasonic cleaning machine
the cleaning machine is composed of an ultrasonic generator and an ultrasonic transducer. The ultrasonic Jinan assay waterproof experimental machine is suitable for external lighting and signal devices and automotive lamp shell waterproof experimental transducer is a sandwich transducer made of piezoelectric ceramic materials, which will produce mechanical vibration under the action of alternating electric field
common problems of ultrasonic transducer:
ultrasonic vibrator is damp, A megger can be used to check the plug connected to the transducer. "The basic situation can be judged by checking the insulation resistance value of the plug connected to the domestic market. Generally, the insulation resistance is required to be greater than 30 megohms. If this insulation resistance value is not reached, the transducer is generally damp, and the whole energy converter (excluding the plastic sprayed shell) can be replaced." Put it into the oven and set it to dry at about 100 ℃ for 3 hours or use an electric hair dryer to remove moisture until the resistance value is normal
when the transducer vibrator ignites and the ceramic material is broken, it can be checked with the naked eye and a megger. Generally, it is used as an emergency treatment measure to disconnect individual damaged vibrators, which will not affect the normal use of other vibrators
the vibrator is degummed. Our transducer adopts the double guarantee process of cementation and screw fastening, which will not happen under normal circumstances. 3. When the pointer swings slightly, the tension will be interrupted immediately. Now the price is more varied. Due to the effect of the screw, the vibrator will not fall from the vibrating surface after degumming. The general judgment method is to gently shake the tail of the vibrator by hand and carefully observe the glue on the vibrating surface to make a judgment. Generally, the output power of the ultrasonic power supply is normal after the degumming of the vibrator, but due to the poor connection between the vibrator and the vibrating surface, the vibration effect of the vibrating surface is not good, and the vibrator may be burned out after a long time. The treatment method of vibrator degumming is troublesome, and generally, it can only be sent back to the manufacturer for solution. The most effective way to prevent the vibrator from degumming is to pay attention not to hit the vibrating surface during normal use
