Select ultrasonic oscillator/The transducer's10 A technique

1. Confirm the cleaning application and installation location

Ultrasonic oscillators and transducers are used for various applications such as cleaning, peeling, dispersing, and degassing. Also, please check the installation location and purpose, such as considering whether it is a good idea to introduce it into a production factory with mist dancing, or whether the integrated laboratory is suitable. Please feel free to inquire about what type of ultrasonic transducer we should use.

2. Check the cleaning solution

Check which cleaning solution to use, such as water-based, petroleum based, solvent based, or alcohol based. Especially when using flammable solvents or acids, please consult the cleaning solution manufacturer in advance.

3. Select the ultrasonic frequency to be used

It is important to determine the appropriate frequency based on the product to be cleaned and the dirt.

-Low frequency（28kHzThe40kHzEtc.): Strong cleaning power, commonly used to remove oil stains and polishing dust. However, due to the long wavelength, it is prone to uneven cleaning, so it is often used in combination with oscillators as a device. Product damage is also likely to occur, so caution must be taken when using products made of aluminum, brass, gold, etc.

-High frequency（100kHzAbove): Commonly used for particle cleaning of hard drives. In the case of particle cleaning, using an appropriate frequency based on particle size can effectively clean.

4. Determine basket shape based on product size

It is very important to determine the shape of the basket during cleaning. In order to determine the shape of the basket, it is necessary to inform us of the required production volume and conduct washing experiments in advance to confirm the following points.

Determine how many products you need to wash per day and how many can be washed at once.

Check the maximum product dimensions (length, width, height). When cleaning various products, it is necessary to check the maximum product size.

Consider conducting a washing experiment to confirm the necessary washing time.

(1)Check if the products can come into contact with each other.

(2)Clean and inspect the finished product according to the actual installation layout.

(3)The product may move due to ultrasonic vibration.

In some cases, special fixtures may be installed to prevent product movement.

According to the results of the washing experiment, how many items should be washed simultaneously? And choose ultrasonic cleaning equipment. If necessary, multiple slots can be added to the ultrasonic cleaning equipment.

After confirmation, determine the appropriate basket shape based on the washing time and size, with a slight margin.

Please consult our staff for specific suggestions.

5. Choose the size of the ultrasonic transducer

according to 4 Determine the appropriate size of the ultrasonic transducer based on the selected basket size. There are various situations depending on the characteristics of the product to be cleaned, but basically we recommend using a size larger than each basket30mmThe ultrasonic transducer.

Example: If the size of the basket is approximately 250mm x 400mmWe suggest using approximately280mm x 430mmThe ultrasonic transducer.

6. Select ultrasonic output

check5The size of the selected ultrasonic transducer. When using about28kHzor40kHzWe recommend adjusting the output density of ultrasonic waves according to the required cleaning power when the frequency is low（WSet the density to approximately0.7to1W/cm²。

Example: Translate the above example into English280 x 430 mmIf the ultrasonic transducer is converted to centimeters, it is28 cm x 43 cmThe area is1204 cm². Suitable in this exampleWThe density is0.7～1Wapproximately843W～1204WTherefore, it is generally chosen900～1200WUltrasonic oscillator and ultrasonic transducer. We can handle a wide range, from an ultrasonic transducer50Wto72 An ultrasonic transducer3600W(It can also exceed this range).

7. Also pay attention to the degree of attenuation and the depth of the water tank

If the product is deeply immersed in the liquid, if the amount of product cleaned at once is large, or if the product is thick, the ultrasonic waves will attenuate, which can easily cause uneven side cleaning. If you want to effectively clean the side, you can install ultrasonic transducers on both sides or around.

8. Select necessary functions

Ultrasonic oscillators have the function of adjusting output intensity, modulating oscillation frequency up and down to reduce scanning unevenness during cleaning, and automatically tracking appropriate frequency based on changes in liquid surface and temperature. With tracking function and constant amplitude function that always maintains a constant output, you can choose the most suitable ultrasonic oscillator according to your budget and purpose.

9. Deciding how to fix the ultrasonic transducer

Ultrasonic transducers can be selected according to the application, such as immersion type with waterproof cables, flange type that allows cleaning tanks to have a relatively flat structure, and type that is directly connected to the tank like a desktop. In addition, if it is a plug-in type, it needs to be fixed in the water tank, so please check the position of the fasteners.

10. Check cable length

The required cables include power lines from the ultrasonic oscillator to the primary side power supply and coaxial cables from the ultrasonic oscillator to the ultrasonic transducer. In addition, if it is an immersion type, please check the necessary length of the waterproof cable.
