2. Principle of ultrasonic cleaning
Ultrasonic cleaning machine generates ultrasonic frequency electricity, which is converted by energy converter into high-frequency mechanical oscillation that is transferred to cleaning fluid. Ultrasound wave is beamed forwards unevenly in the cleaning fluid to make the fluid vibrate and generate tens of thousand of micro bubbles, which form and grow in the negative pressure area where the ultrasound wave travels longitudinally and close (crush out) in positive pressure area. Formation, growth and quick closure of the micro bubbles is called cavitation. In cavitation, closure of bubbles will generate instantaneous high pressure higher than 1,000 times of atmospheric pressure, and the continuous high pressure force hits surface of the work piece like numerous small blasts to peel off dirty on the surface and in clearance of object, and this is how the ultrasonic cleaning machine operates.

6. Installation and Preparation
1. Place the machine horizontally at a well-ventilated and dry location.
2. Select appropriate detergent, cleaning water or other solution based on properties of work piece to be cleaned.
3. Properly and firmly connect the plug to a three-pin power socket which is grounded reliably to ensure safety.
7. Operation Instructions
Figure 1
Operation Instructions:
1. Load cleaning fluid into the tank and connect the power supply (which shall be grounded reliably).
2. Adjust the ultrasonic working time: twist the knob to set the time, adjust the ultrasonic working time range: 1-60minutes, at this time the ultrasonic working indicator light is on, the ultrasonic working;When the ultrasonic working time is up, the working indicator light is off and the ultrasonic stops working.
3. Adjust the heating temperature: twist the knob to set the heating temperature, the range of heating temperature is 30-80 degree. When the actual water temperature is lower than the set temperature, the heating indicator lights up and starts to work. When the actual water temperature is higher than the set temperature, the heating indicator lights out and the heating stops.
8. Factors Influencing Performance
1. Ultrasonic power density:Higher power density results in better cleaning performance and higher cleaning speed. Higher power density is appropriate for cleaning of work piece with stubborn dirt, and lower power density is suitable for any precision work piece (generally ultrasonic power density ranges between 0.01-0.02w/ml).
2. Ultrasonic Frequency: Lower frequency results in better cavitation performance. Higher frequency contributes to better refraction/ reflection performance. Lower frequency should be applied for cleaning of simple surface while higher frequency for cleaning of complex surface with deep or inaccessible hole. (80KHz, 120KHz)
3. Cleaning temperature: Ultrasound wave will present the best cavitation performance at a temperature range between 40~50°C.Higher cleaning temperature facilitates breakdown of dirt, while a temperature above 70°C~80°C may impair effect of ultrasound wave and deteriorate cleaning performance.
4. Cleaning duration:Longer cleaning duration presents better cleaning performance (except for special material).
5. Other influential factors include type and properties of cleaning fluid and the dirt to be removed.
9. Maintenance
This machine shall be used, maintained by dedicated personnel and a full check on the equipment shall be performed regularly.
1. Check the power supply and line connections for any looseness, overheating, damp absorption or poor contact.
2. Inspect sealing of the bottom board of cleaning tank for any leakage.Check the joint between drain pipe and cleaning tank for leakage.
3. For looseness of ultrasound wave converter or burnout of power tube, contact the manufacturer immediately.
4. The ultrasound wave equipment shall be operated and stored at well-ventilated, dry and clean place to facilitate good performance and long service life.
10. Malfunctions and Solutions
malfunctions | solutions |
Failure of Ultrasonic Wave | (1) Check whether the power cable has been connected properly (by inspecting operation of power indicator lamp). (2) Check whether PCB has been connected properly to the power socket. (3) Check whether the fuse tube is broken |
Weak ultrasonic wave | (1) Check whether the power voltage is normal. (2) Inspect whether the energy converter get loose or there is any shock absorption material or work piece under the tank. (3) Check whether cleaning fluid temperature is normal (recommended operating temperature is higher than 30 degree) or there are many air bubbles in the fluid or on the tank wall (repeated power-on/off will reduce the bubbles). (4) Check whether the solvent is added excessively. |
No heating | (1) Check whether target temperature is too lower (lower than current actual temperature). (2) Check whether the heater cable is disconnected or gets loose. (3) Check whether heater is broken (due to shortage of cleaning fluid) |
Electric leakage | (1) Check whether the machine has absorbed damp or corroded. (2) Check whether cable tray to each component is damaged, loosened or broken. (3) Check whether the earthing wire is in good condition. |

11. Application Safety
Safety Considerations
1. Warns: This product contain dangerous voltage, so do not start it at a high-temperature or humid location to avoid electric shock.
2. Do not impose great impact to this machine, and handle it with care to prevent impairment to performance or life span of it.
3. Locate this machine properly to avoid any accident resulted from children's access to it.
4. Perform any maintenance operation only after the power supply is disconnected to avoid any safety accident.
5. The machine contain high voltage during operation, so do not dismantle its enclosure to avoid any hazard.
6. For any damage to the power cable, contact your service center or your dealer for replacement.
7. Clean the enclosure with soft dry cloth after disconnecting the power cable.
8. Protect the machine from splash of rain or water to avoid electric shock or fire, and keep it away from any location with high temperature or humidity.
9. For reason of personal safety, do not dismantle the enclosure for repair or change on your own.
Safety Considerations
1. During normal operation of ultrasonic generator, a consistent sound is resulted from the harmonic oscillation of the tank body impacted by ultrasound wave, and no agitation but ripple is caused on the surface of cleaning fluid by explosion of cavity. In case of discontinuous oscillation, increase or reduce the cleaning fluid by a small quantity to eliminate such oscillation to facilitate cleaning of work piece.
2. While ensuring adequate cleaning of work piece, keep the generator operating intermittently, as long-term consecutive operation may result in high temperature insides and accelerate aging of electronic components in it.
3. Absolutely do not use any inflammable detergent.
4. Start heating or ultrasonic wave generator only when the cleaning tank contains fluid, or otherwise the machine may be burnt out or even result in fire.
5. Prevent splash of cleaning fluid or water into the machine or energy converter, which may cause electric leakage or short circuiting, and thereby damage to the converter.
6. Any foreign matter falling into the tank shall be taken out immediately.
7. Before changing or discharging the cleaning fluid, make sure the fluid is at normal temperature and the ultrasonic wave generator is shut down and the power supply is disconnected.
8. Remove any dirt in the tank after operation.
9. Keep the external surface of the machine clean.
