1. The ultrasonic transducer is damp. Generally, it can be judged by checking the plug connected to the transducer with a megger, and checking the insulation resistance value between the positive and negative poles of the transducer. The method is to put the whole transducer into an oven and set it to about 100℃, and dry it for three hours or use a hair dryer to remove moisture until the resistance value is 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 use of other vibrators.
3. Perforated stainless steel vibrating surface. Generally, ultrasonic transducers may experience perforation on the vibrating surface after 10 years of full-load use. This is caused by long-term high-frequency vibration fatigue of the stainless steel plate on the vibrating surface. Perforations on the vibrating surface indicate that the service life of the transducer has been reached. Maintenance Generally, it can only be replaced.
