Ultrasonic cleaning machine to use units of enterprises and how to choose a suitable ultrasonic cleaning machine, which is a complex problem, in order to better meet the needs of production and resource use of optimization, the author thinks that should from the following perspectives consider how to choose the ultrasonic cleaning equipment:
1, cleaning process, cleaning workpiece material, structure, physical and chemical properties, cleaning the workpiece weight, size, which determines the use what kind of cleaning process, selection of ultrasonic cleaning and other cleaning methods. The precondition of ultrasonic cleaning is based on the liquid, and is usually a good conductor solution for water based cleaning solution or other ultrasonic wave.. Choose the production type ultrasonic equipment can choose to do experiments look how to wash the effect. Ultrasonic cleaning and conventional cleaning methods. Such as the advantages and disadvantages of high-pressure cleaning, steam cleaning, or the effective combination of different cleaning methods to achieve the best results. In addition to ultrasonic cleaning, but also consider supporting system, such as rinsing, circulation filtration and drying, etc.
2, the ultrasonic cleaning equipment itself related parameters: the main ultrasonic power, ultrasonic frequency, cleaning the grid and other washing machine accessories, etc.
(1) ultrasonic power: ultrasonic power on the cleaning effects depending on ultrasound power density, the per unit area of the ultrasonic power, generally in a certain range, power density more ultrasonic effect stronger, but is not a power density, the bigger the better, over the general assembly formation strong standing waves, resulting in waste, will aggravate the cavitation corrosion of the workpiece, especially noble crossing the degree of precision parts and components, more to be careful in choosing reasonable power density. Generally laboratory with ultrasonic per liter 8-10W. Also a problem is the power distribution structure, reasonable distribution can reduce the influence of standing wave, to improve the cleaning effect, general height is not too high cleaning machine the bottom ultrasound, deep the bottom and sides of ultrasonic on three sides, on both sides of the ultrasonic and multiple ultrasonic, the specific choice of the need for cleaning process.
(2) ultrasonic frequency, ultrasonic frequency 20KHz to 120 kHz, ultrasonic equipment commonly used frequency is 20kHz, 28KHZ and 40KHz and low and intermediate frequency amplitude larger, noise larger, cavitation corrosion is strong, strong decontamination ability, suitable for dirt heavier industrial parts cleaning; high frequency for the cleaning chamber and precision parts cleaning.
(3) the configuration of the cleaning accessories: temperature control, space truss, etc.. Reasonable selection of washing basket can reduce the ultrasonic attenuation and improve the cleaning effect; ultrasonic cleaning in a certain temperature range can achieve the best cleaning effect, base aqueous ultrasonic cleaning machine for the best cleaning temperature between 30 to 60 DEG C, in addition to considering the, and some require high temperatures in order to clean the workpiece can be the first hot soak in ultrasonic cleaning.
(4) the material of the ultrasonic cleaning trough, the material of the cleaning trough is the important factor that affects the ultrasonic cost, and the ultrasonic cleaning equipment of the same parameters is different from different material.
(5) the performance of ultrasonic transducers and other core components
(6) the bonding process of the ultrasonic manufacturer equipment
(7) the ultrasonic cleaning equipment circuit and control mode
