Basic principle of ultrasonic cleaning machine
Ultrasonic cleaning machine is based on the basic principle of ultrasonic cavitation. When the bubble formed by ultrasonic waves suddenly bursts, it will also produce a pressure above 1000 atmospheric pressure. This continuous strong micro-explosion and shock wave will replace labor, so that the stains on the surface of the cleaned object will be destroyed and peeled off immediately.
Before standardizing the use of ultrasonic cleaning machine, the operator must understand the value of the equipment. In general, there are three kinds of ultrasonic waves, namely infrasound, sound wave and ultrasonic wave. The frequency of infrasound wave is below 20Hz, the frequency of sound wave is between 20 Hz and 20k Hz, and the frequency of ultrasonic wave is above 20 kHz.
Infrasound waves and ultrasonic waves are generally inaudible to human ears. Ultrasonic wave has high frequency, short wave length, good directivity and strong penetration, which is the main reason for designing and manufacturing ultrasonic cleaning machine.
Ultrasonic cleaning machine is mainly composed of ultrasonic cleaning tank and ultrasonic generator. The ultrasonic cleaning tank is firm, elastic and corrosion-resistant, and the bottom is equipped with an ultrasonic transducer vibrator. Ultrasonic waves can be transmitted to the transducer through the cable connection line, and the transducer and the vibrating plate generate high-frequency vibration, so that the organic solvent in the tank can be cleaned by ultrasonic waves.
operating procedure
When using this equipment, the operator must strictly implement the following standards for phased operation.
First, connect the cable between the tank and the generator;
Secondly, pour the cleaning liquid into the tank. It should be noted that when the object to be cleaned is put in, the amount of cleaning solution poured in is about three quarters of the whole. Then put the object to be cleaned into the tank, and then plug in the power plug;
Finally, set the cleaning time before starting the machine.
When using the equipment, there are several problems to pay attention to:
First, the power supply of ultrasonic bottle washer and electric heater must have a good grounding device;
Secondly, the ultrasonic bottle washer is forbidden to start without cleaning liquid, in other words, the ultrasonic switch cannot be turned off without adding a certain amount of cleaning liquid into the cleaning cylinder;
Three, cleaning equipment with heating equipment, it is forbidden to open the heating switch when there is no liquid;
Fourthly, it is not allowed to hit the bottom of the cleaning cylinder with heavy objects to prevent the transducer chip from being damaged.
The main reason for unsatisfactory cleaning
A, ultrasonic bottle washing machine tank cleaning liquid level is not good, also can cause the cleaning is not ideal. It is necessary to adjust the level of cleaning machine to change the cleaning effect.
Secondly, if the ultrasonic frequency coordination is not adjusted well, it is easy to see that the cleaning of the ultrasonic cleaning machine is not satisfactory and must be adjusted again.
Thirdly, if the temperature of the liquid in the tank is too high, it will also cause unsatisfactory cleaning, so it is necessary to control the temperature of the cleaning liquid.
Fourthly, improper use of cleaning solution is also a reason why ultrasonic cleaning machine is not ideal, so you must choose the cleaning solution that suits you.
In fact, the high-speed oscillation of ultrasonic wave can clean and sterilize the surface of the object to be cleaned, and the cavitation effect is obvious. The cleaning efficiency is much higher than that of manual cleaning, and there is no cleaning blind area and damage. But these effects are based on the correct operation process and reasonable and effective production environment. Therefore, in order to achieve better cleaning effect, the operator must pay attention to some operational matters.
Daily maintenance and maintenance
1. Keeping the equipment workplace ventilated, dry and clean is conducive to the long-term efficient operation of the equipment and the optimization of working conditions;
2. When the cleaning liquid is too dirty, it should be properly handled, and the stains in the tank body and the liquid storage tank should be cleaned on time to keep the inside and outside of the cleaning tank clean, which is helpful to improve the durability of the cleaning tank;
3. The electrical control box and equipment vents should be far away from water vapor, corrosive substances and dust, and the attached dust should be cleaned up with compressed air in time;
4. Test the insulation performance of the equipment on time, regularly check the aging electrical components, and check the grounding wire to ensure that the equipment is well grounded. This project needs an electrician with professional experience to carry out;
5. Test the power supply on time to ensure that it meets the power supply voltage requirements of the equipment and avoid working for a long time under the unstable power supply that is too high or too low;
6. For the equipment with filtering device, replace the filter element in time;
7. With the transmission mechanism, the lubricant such as butter and engine oil should be filled on time as required, and the gear oil of the reducer should be replaced in time to ensure that the moving parts work under good lubrication conditions.
Maintenance points of ultrasonic cleaning machine
1. In the cleaning process, people should pay attention to many places, especially it is forbidden to spill conductive liquid (such as water) from the air inlet at the top of the ultrasonic control cabinet, otherwise it will seriously affect the circuit system of the cleaning machine;
2. Always keep the machine clean when it is placed, and turn off the power when it cannot be used;
3. The cleaning machine equipment is not an anti-collision product, so it must avoid collision or violent vibration to the machine when using it;
4. The machine is not good for electronic components and circuits at high temperature, so be sure to stay away from heat sources;
5. Stay away from this heat source to prevent the machine from being placed in a humid environment;
6. The continuous running time of the machine cannot exceed 4 hours. If the continuous operation time is too long:
7. After the cleaning machine runs for a long time, turn the power knob to zero before stopping, and turn off the fan after working for 3 ~ 6 minutes to ensure the heat dissipation inside the power supply;
8. The cleaning solution should be precipitated, filtered or replaced in time to ensure the cleaning effect.
In order to make the system cleaning machine run normally for a long time, in addition to avoiding irregular operation, it is also necessary to check and maintain the cleaning machine regularly and do the following work well:
① Regularly clean the contaminated cleaning solution in the oil storage tank.
(2) Let the oil pump run on time for at least 10 minute each time.
(3) After the cleaning machine is used, cover it with a cover to prevent pollution and moisture.
The above are the main points about the daily operation, maintenance and maintenance of the ultrasonic cleaning machine. To sum up, it is no different from other equipment maintenance, but there are many problems that cannot be ignored when using it, which need special attention. Only by using the ultrasonic cleaning machine well can we ensure the normal work of the ultrasonic cleaning machine.
