How does ultrasonic cleaning machine work? What can ultrasonic cleaners wash?

Ultrasonic cleaner is used to remove contaminants of the instrument, through the transducer will power ultrasonic frequency source of sound energy and converted into mechanical vibration to clean items, widely used in industry, national defense, biomedicine and other aspects.

Ultrasonic cleaning machine working principle

The working principle of ultrasonic cleaning is that when working in the ultrasonic cleaning machine, the liquid emits a large enough ultrasonic energy, the ultrasonic frequency vibration is added to the cleaning liquid, and the internal liquid will be used and compressed, when the liquid is used, will produce bubbles, and when the liquid is compressed, the bubbles will be compressed, it will be crushed and broken, which will occur ” ultrasonic cavitation effect”, in fact, the principle of ultrasonic cleaning is through the cavitation effect to achieve the effect of oil removal and decontamination.

Ultrasonic cleaning machine, sometimes called ultrasonic cleaning instrument or ultrasonic cleaning machine, including the following basic components:

Ultrasonic cleaning tank: ultrasonic cleaning tank is equipped with liquid and the items to be cleaned.

Ultrasonic generator: ultrasonic generator, also known as ultrasonic drive power, electronic box, ultrasonic controller, is an important part of the high-power ultrasonic system. Ultrasonic generator role is to convert the utility power to match the ultrasonic transducer high-frequency alternating current signal, drive the ultrasonic transducer work.

Ultrasonic transducer: the function of the ultrasonic transducer is to convert the input electrical power into mechanical power (i.e., ultrasound) and then pass out, and its own consumption of a small part of the power.

Ultrasonic transducer is an energy conversion device that converts high frequency electrical energy into mechanical energy. It is mainly used in ultrasonic cutting equipment, ultrasonic atomization spraying equipment, ultrasonic metal melt processing equipment, ultrasonic welding equipment, ultrasonic liquid processing acoustic chemical equipment and ultrasonic metal fatigue experimental equipment, the frequency of the transducer is usually between 20KHz and 120KHz.

Ultrasonic generator, usually called ultrasonic electric box, ultrasonic generator source, ultrasonic power supply. Its role is to convert our mains electricity (220V or 380V, 50 or 60Hz) into a high frequency AC signal that matches the ultrasonic transducer. From the form of amplification circuit, you can use a linear amplifier circuit and switching power supply circuit, high-power ultrasonic power supply from the conversion efficiency considerations are generally used in the form of switching power supply circuit. Linear power supply also has its unique range of applications, it has the advantage of not strictly required circuit matching, allowing continuous and rapid changes in operating frequency.

What can be cleaned by ultrasonic cleaning?

Ultrasonic cleaning is suitable for cleaning a variety of materials, including metals, glass, rubber, ceramics and some hard plastics. Ultrasonic cleaning is particularly useful for removing tightly adhered contaminants from complex items with blind holes, cracks and grooves. Contaminants removed by ultrasonic cleaning include dust, dirt, oil, grease, pigments, flux, fingerprints and polish.

Currently the more common ultrasonic cleaning fluid is generally water-based cleaning agent. Water-based cleaning agents are generally composed of a variety of surfactants, degreasing agents, can be diluted with water to reduce cleaning costs. The use of solvent-based cleaning agents should be avoided. This will produce instability for solvent-based cleaning agents. Acid cleaning solution, bleach should also be avoided in general, long-term use will cause damage to the surface of the stainless steel tank and cleaning target equipment, but when they are used in the cleaning process, such as with a large mouth beaker as an indirect cleaning container can be used.

Ultrasonic cleaning systems are used in many industries, including medical devices, automotive, dental, electronics, and jewelry. Ideal items for ultrasonic cleaning include medical and surgical instruments, vaporizers, firearms, window blinds, industrial machine parts and electronic equipment.

The time required for ultrasonic cleaning depends on the material and dirt, but a typical cleaning time is 3 to 6 minutes. Some delicate items such as electronics may require longer cleaning times. Higher temperatures help remove dirt faster, so most industrial parts cleaners use high temperatures of 50 to 65°C.

It should be noted that ultrasonic cleaning itself does not sterilize the item. However, appropriate cleaning additives can be selected according to the nature of the dirt. If the cleaning process to add disinfection-related liquids or in accordance with the availability of ultraviolet disinfection, then sterilization can be carried out.

Ultrasonic cleaning machine use steps.

1、the items to be cleaned into the cleaning basket of the cleaning machine, and then the cleaning basket into the cleaning tank. Please do not put the items directly into the cleaning tank, so as not to damage the equipment and affect the cleaning effect.

2、According to different products or cleaning effect, pour in cleaning solution, water or aqueous solution in proportion, the minimum water level should not be lower than the minimum water level marked in the product manual, and the maximum water level should not exceed the maximum water level marked in the product manual.

3、connect 220V/50Hz power three-prong socket, turn on the power.

4、open the ultrasonic cleaning machine switch button, green switch on the normal operation.

5、open the ultrasonic cleaning machine temperature control, according to the item cleaning requirements to adjust the temperature.

6、the temperature indicator goes off, the heater reaches the required requirements, the heater stops working, if lower than the set temperature, the heater will continue to automatically heat.

7、When the heating temperature reaches the product cleaning requirements, the cleaning timer can be turned on, and the working time of the timer can be set according to the product cleaning requirements.

8、The cleaning time of general items is 10 minutes to 20 minutes. For cleaning difficult workpieces, the cleaning time can be extended appropriately to ensure the cleaning effect.

9、The timer position can be adjusted arbitrarily within 1-20min, also can be adjusted in the normally open position. The general cleaning time is 10-20min. for the cleaning of particularly difficult parts, the cleaning time can be extended appropriately.

10、After cleaning, the cleaning tank remove the cleaning basket, rinse with warm water or in another solvent-free warm water cleaning tank.

11、Items should be dried, stored and assembled after cleaning.
