Ultrasonic cleaner repair

　　1。 There is no ultrasonic, no output, turn on the ultrasonic generator, and the cooling fan turns.

The problems are: check whether the power tube of the generator is burned, if the power tube is burned, you can observe whether the fuse of the power board of the generator is blown or burst. If it is burned, the power tube and insurance are replaced. Resistance. Ultrasonic cleaner repair

　　2。 There is no ultrasonic generator, cooling fan, working indication, etc.

The problems are: see if there is a frequency output on the generator drive board, or disconnect the oscillator output line with a multimeter to measure the output end of the generator (output spray cleaning machine transformer power inlet ends) to take the voltage gear AC750V, adjust the external potentiometer to the maximum to see if there is a voltage of 180~240V, if there is a voltage of 180~240V, choose to see if the oscillator is short-circuited, the multimeter conduction file. Measure whether it is on, such as the conduction selection, check whether the oscillator wire is broken and whether the two wires are connected together or the oscillator is short-circuited.

　　3。 The ultrasonic generator can't be turned on empty, and it trips as soon as it is opened. Ultrasonic cleaner repair

The problems are: see if there is a short circuit in the

power line of the generator, see if there is a problem with the rectifier bridge of the generator (take the diode file of the multimeter) and measure whether there is a short circuit in the four pins, if there is a short circuit, choose to rectify

If there is a problem with the bridge, you can replace one.

　　4。 The ultrasonic generator is working normally, and the power cannot be adjusted.

The problems are: to see if there is a problem with the thyristor, the

multimeter conduction file to measure whether there is a short circuit in the three pins of the thyristor, the most important thing is to see whether the thickest two pins of the thyristor are on, if it is reversed, it can be replaced.

　　5。 No ultrasound, no output.

There are problems. If the generator indicates the amount of light, the fan also rotates, and there is a frequency display. If not, check whether the thyristor is normal, and see if the generator driver board 7812 has a 12V regulated output. If so, or see if there is a problem with the 772 in the SCR control part of the launchpad. If so, replace.

　　6。 There is ultrasound, the sound of ultrasound is very abnormal, and the ultrasound strength is not good.

(1) USE THE FREQUENCY TABLE TO CHECK WHETHER THE OUTPUT FREQUENCY IS WITHIN THE WORKING FREQUENCY RANGE OF THE TRANSDUCER (THE FREQUENCY OF 28KHZ TRANSDUCER SHOULD BE 27KHZ-31KHZ, AND 40KHZ TRANSDUCER IS 38KHZ-42KHZ). If the difference is too large, the normal operating frequency can be restored by adjusting the frequency potentiometer. Ultrasonic cleaner repair.
