Ultrasonic cleaning machine cleaning efficiency, is very good with the equipment, but as a high-tech appliances, it is once a failure, maintenance is also very troublesome, then what are the common failures of ultrasonic cleaning machine? Ultrasonic cleaner bad how to repair? Ultrasonic cleaning machine faults and solutions are:
1, transducer damage
Reason for failure: ultrasonic cleaning machine for a long time in the use of the state of boot, the temperature gradually rises, resulting in colloid melting transducer off or transducer ceramic part of the fracture.
Maintenance method: using a shaking table to measure the insulation strength of the transducer, insulation strength in the 200MΩ below has been unable to use, replace the new transducer can be.
2, power tube damage
Reason for failure: ultrasonic cleaner for a long time uninterrupted use, cleaning liquid is too little will lead to short-circuit power tube.
Maintenance method: power tube connected to the motherboard, using a multimeter to measure the resistance of the power tube on both sides of the pins, under normal circumstances should be about 22Ω, otherwise you need to replace the power tube.
3, power on the power supply does not respond, does not show
Reason: ground wire mixed with the fire wire or zero line lead to damage to the power supply seat insurance, or ultrasonic cleaner components aging caused by a short circuit.
Maintenance method: take out the insurance to see if there is a break, and use a multimeter through the broken file to measure whether the disconnection, if the damage is to replace the new insurance.
4, voltage regulator or bridge damage
Reason for failure: power tube resistance is small or short-circuit switching will cause voltage regulator and diode rectifier circuit damage.
Maintenance method: using a multimeter diode file measurement, forward resistance value of about 70Ω, reverse ∞. If the value deviation is too large or forward resistance is also ∞, replace the new voltage regulator.
5, inductance, isolation transformer damage
Reason for failure: ultrasonic cleaner for a long time leading to inductance, transformer and other heat dissipation components due to high temperature and melting, burned.
Maintenance method: generally these two devices are damaged are burned, can be seen directly burned traces, can not be repaired, can only replace the new device.
6, no ultrasonic output
Reason for the failure: may be the transducer and ultrasonic power board connected to the plug loose, blown fuse, ultrasonic power generator failure, transducer failure.
Maintenance method: step by step to identify the cause of the problem, and then repair or replacement.
7, the cleaning effect is not ideal
Reasons for failure: improper level of cleaning fluid in the cleaning tank, ultrasonic frequency coordination is not adjusted, the cleaning tank liquid temperature is too high, improper selection of cleaning fluid.
Maintenance method: If the frequency is not adjusted, adjust the frequency can be; the other is the problem of cleaning fluid, according to the cause of the problem to adjust.
Anything has its use of life, ultrasonic cleaner if not used properly is prone to failure, even if the maintenance of its service life will be greatly reduced, so we have to pay attention to the maintenance of ultrasonic cleaner.
Two, how to maintain the maintenance of ultrasonic cleaning machine
To use the ultrasonic cleaning machine in the process of less or no failure, we must pay attention to the usual maintenance and maintenance work:
1, routine maintenance
Keep the equipment workplace ventilation, dry, clean, away from water vapor, corrosive gases, dust, and regularly clean up the dust attached to the compressed air. Attached to the dust, ultrasonic cleaning machine to provide good working environment conditions; cleaning fluid and internal dirty should be dealt with in a timely manner, regularly clean up the cleaning tank, storage tank dirt, to keep the cleaning tank and the appearance of the clean.
2, regular maintenance
Regular testing of the insulation of the equipment, easy to age the electrical components for regular inspection, check the grounding line before use every day to ensure that the equipment is well grounded and then work, regular testing of the power supply to see if the equipment meets the requirements of the power supply voltage and so on.
