Transducer problem of ultrasonic plastic welding machine
Frequently Asked Questions of Ultrasonic Transducers:
If the ultrasonic vibrator is damp, you can use a megohmmeter to check the plug connected to the transducer. Pin 2 is the positive pole of the ultrasonic transducer, and pin 3 is the negative pole of the transducer.
The housing of the transducer is connected. Check the insulation resistance between the 2 and 3 pins to determine the basic situation. Generally, the insulation resistance is required to be greater than 30 megohms. If the insulation resistance value is not reached, the transducer is usually damp. You can put the transducer as a whole (excluding the plastic-sprayed shell) into an oven and set it to about 100 ℃ for 3 hours or use a hair dryer to remove moisture to the resistance value. So far.
The transducer vibrator is ignited 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 use of other vibrators.
Vibrator degumming, our transducer adopts double guarantee process of cementing and screw fastening. Under normal circumstances, this will not happen. Due to the action of screws, the vibrator will not fall from the vibrating surface after degumming. The general judgment method It 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 vibrator is degummed. However, 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 burnt out after a long time. The processing method of vibrator degumming is more troublesome, and in general, it can only be sent back to the manufacturer for solution. The most effective way to prevent the vibrator from degumming is to not hit the vibrating surface during normal use.
Perforation on the vibrating surface. Generally, the perforation of the vibrating surface may occur after the full load of the transducer for a year. This is due to the 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 been When it arrives, it can only be replaced.
The panel control and display part includes the power switch on the generator panel, the power adjustment potentiometer, and the power output indicator to complete the power switch, power adjustment, output power status display and other functions of the cleaning machine.
