What are the common problems of ultrasonic cleaning machine generator?

(1) turn on the power switch of the ultrasonic cleaning machine, and the indicator light is not on. In this case, it is necessary to check whether the power switch is intact and whether the leakage switch is closed during maintenance. If the switch is intact, check whether the fuse is overloaded and blown, which can be basically solved.

(2) after the power switch of the ultrasonic cleaning machine is turned on, the indicator light is on, but there is no ultrasonic output. This situation is complicated. During maintenance, first check whether the connecting plug between the transducer and the ultrasonic power board is loose, and then check whether 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 check whether the live line is connected. After troubleshooting the generator, check whether the ultrasonic transducer is burnt out and whether it needs to be replaced.

(3) the DC fuse of ultrasonic cleaning machine is blown. The rectifier bridge stack or power tube may be burned, or the transducer may be aged and the current may be unstable, which may cause the failure of the power generator. Pay more attention during maintenance.
