浅析超声波清洗机功率和功率密度

作者:超声波清洗机生产厂家 来源:http://www.jnthcsb.com 时间:2021-01-12 11:26:20

超声功率和超声频率是影响超声波清洗机清洗效果的两个重要参数,超声波功率是指超声波在单位时间内所做的功,其单位为W,超声清洗机功率取决于超声波清洗槽上面黏粘的超声波能量转换器的功率和超声波功率发生器的调功装置,一般超声波能量转换器振子的数目和单个换能器的功率(一般常见的单个超声波换能器功率为40W-100W之间)相乘即为超声波清洗机设备的最大超声功率。

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.

超声波功率对超声波清洗机清洗效果的影响主要体现在超声功率密度对清洗效果的影响,功率密度是单位面积上的超声功率(功率密度=发射功率(W)/发射面积(cm2)通常≥0.3W/cm2),一般超声清洗设备能量转换器粘结在清洗槽底部,计算面积主要是底部面积,有时候要适当考虑超声波清洗槽高度对功率密度的影响,比较深得清洗槽要考虑多面超声,计算面积就要加大。

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.

超声功率密度一般不小于0.3W/cm2,不同的清洗工艺对功率要求不一样,一般实验室用超声波清洗器功率密度较小在0.3W/cm2左右,工业用超声波清洗机功率密度因清工件类型、洗洁度要求不同而差别较大,一般功率密度不小于0.5W/cm2.超声波清洗并非功率密度越大效果越好,功率密度越大对工件的超声波的空化腐蚀也就越大,因此在选择功率密度时要参考实践经验和专业技术人员意见.

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
