Maintenance and Repair of Ultrasonic Cleaning Equipment
The ultrasonic cleaning machine is mainly composed of an ultrasonic generator and an ultrasonic transducer. The ultrasonic transducer is a sandwich-type transducer made of lead zirconate titanate piezoelectric ceramic material. The piezoelectric ceramic material has a dimensional change under the action of an electric field. The phenomenon that the transducer will produce mechanical vibration under the action of the alternating electric field.
Ultrasonic transducer FAQ:
1. When the ultrasonic vibrator is damp, you can use a megohmmeter to check the plug connected to the transducer, of which 2 feet are the positive pole of the ultrasonic transducer, and 3 feet are the negative pole of the transducer and are connected to the outer shell of the transducer. Check, the insulation resistance value between 23 feet can judge the basic situation, generally requires the insulation resistance to be greater than 30 megohms. If the insulation resistance value cannot be reached, generally the transducer is damp. You can put the whole transducer (excluding the plastic-sprayed shell) into the oven and set it to dry at about 100℃ for 3 hours or use a hair dryer to remove moisture to the resistance value. until normal.
2. The transducer vibrator ignites and the ceramic material is broken. It can be checked with the naked eye and a megohmmeter. Generally, as an emergency measure, individual damaged vibrators can be disconnected without affecting the normal operation of other vibrators. use.
3. The vibrator is degummed. Our transducer adopts the double guarantee process of gluing and screw tightening. This situation does not occur under normal circumstances. Due to the action of the screw, the vibrator will not fall from the vibration surface after degumming. The general judgment method is to gently shake the tail of the vibrator by hand, and carefully observe the glue condition of the vibrating surface to make a judgment. Generally, after the vibrator is degummed, the output power of the ultrasonic power supply is normal, 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 burn out after a long time. The treatment method of degumming of the vibrator is more troublesome, and in general, it can only be sent back to the manufacturer to solve. The most effective way to avoid degumming of the vibrator is to be careful not to hit the vibrating surface during normal use.
