Now that the severe winter has arrived, many machines expand and contract due to the cold weather, which leads to numerous malfunctions. Generally speaking, machines are more prone to failure in winter. If we want to accurately and quickly identify ultrasonic cleaning machines, it can effectively reduce the risk of enterprise losses and also allow us to learn a skill. The following common faults usually occur! When the power switch of the ultrasonic cleaner is turned on, the indicator light does not light up and there is no ultrasonic output. Reason: A. The power switch is damaged and there is no power input. B. The ACFU fuse has blown. After turning on the power switch of the ultrasonic cleaner, the indicator light is on, but there is no ultrasonic output. Reason: A. The connection plug between the transducer and the ultrasonic power board is loose; B. The DCFU fuse blew. C. Fault of the ultrasonic power generator; D. Transducer failure. 3. The DC fuse DCFU of the ultrasonic cleaner has blown. Cause: A. The rectifier bridge stack or power transistor was burned out; B. Transducer failure. We should always be aware of where the machine malfunctions. Regarding these issues, we have common sense about maintenance to teach everyone! 1. The cleaning machine is composed of an ultrasonic generator and an ultrasonic transducer. The ultrasonic transducer is a sandwich type transducer made of piezoelectric ceramic material. 2. If the transducer oscillator sparks and the ceramic material breaks, it can be inspected by combining the naked eye and a megohmmeter. Generally, as an emergency measure, individual damaged oscillators can be disconnected without affecting the normal use of other oscillators.
