超聲功率和超聲頻率是影響超聲波清洗機(jī)清洗效果的兩個重要參數(shù),超聲波功率是指超聲波在單位時間內(nèi)所做的功,其單位為W,超聲清洗機(jī)功率取決于超聲波清洗槽上面黏粘的超聲波能量轉(zhuǎn)換器的功率和超聲波功率發(fā)生器的調(diào)功裝置,一般超聲波能量轉(zhuǎn)換器振子的數(shù)目和單個換能器的功率(一般常見的單個超聲波換能器功率為40W-100W之間)相乘即為超聲波清洗機(jī)設(shè)備的大超聲功率。
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.
超聲波功率對超聲波清洗機(jī)清洗效果的影響主要體現(xiàn)在超聲功率密度對清洗效果的影響,功率密度是單位面積上的超聲功率(功率密度=發(fā)射功率(W)/發(fā)射面積(cm2)通常≥0.3W/cm2),一般超聲清洗設(shè)備能量轉(zhuǎn)換器粘結(jié)在清洗槽底部,計(jì)算面積主要是底部面積,有時候要適當(dāng)考慮超聲波清洗槽高度對功率密度的影響,比較深得清洗槽要考慮多面超聲,計(jì)算面積就要加大。
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.
超聲功率密度一般不小于0.3W/cm2,不同的清洗工藝對功率要求不一樣,一般實(shí)驗(yàn)室用超聲波清洗器功率密度較小在0.3W/cm2左右,工業(yè)用超聲波清洗機(jī)功率密度因清工件類型、洗潔度要求不同而差別較大,一般功率密度不小于0.5W/cm2.超聲波清洗并非功率密度越大效果越好,功率密度越大對工件的超聲波的空化腐蝕也就越大,因此在選擇功率密度時要參考實(shí)踐經(jīng)驗(yàn)和技術(shù)人員意見.
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
