Ultrasonic power and ultrasonic frequency are two important parameters that affect the cleaning effect of ultrasonic cleaning machine. Ultrasonic power refers to the work done by ultrasonic in unit time, and its unit is w. the power of ultrasonic cleaning machine depends on the power of ultrasonic energy converter stuck on the ultrasonic cleaning tank and the power regulating device of ultrasonic power generator. Generally speaking, the power of ultrasonic energy converter vibrator The number and the power of a single transducer (generally, the power of a single ultrasonic transducer is between 40w-100w) are multiplied to be the maximum ultrasonic power of the ultrasonic cleaning machine.
The influence of ultrasonic power on the cleaning effect of ultrasonic cleaning machine is mainly reflected in the influence of ultrasonic power density on the cleaning effect. The power density is the ultrasonic power per unit area (power density = transmitting power (W) / transmitting area (cm2) is usually ≥ 0.3w/cm2). Generally, the energy converter of ultrasonic cleaning equipment is bonded at the bottom of the cleaning tank, and the calculated area is mainly the bottom area, sometimes it needs to be adjusted The influence of the height of the ultrasonic cleaning tank on the power density should be properly considered, and the calculation area of the cleaning tank should be increased.
Ultrasonic power density is generally not less than 0.3w/cm2. Different cleaning processes have different power requirements. Generally, the power density of Ultrasonic Cleaners Used in laboratories is relatively low, about 0.3w/cm2. The power density of industrial ultrasonic cleaners varies greatly due to different types of cleaning workpieces and cleaning requirements. Generally, the power density is not less than 0.5w/cm2 Good, the higher the power density is, the greater the cavitation corrosion of ultrasonic wave will be. Therefore, the practical experience and the opinions of professional technicians should be referred when selecting the power density
