超声波清洗机工作频率

Working frequency of ultrasonic cleaning machine

当工作频率非常低（在人类听觉范围内）时，就会出现噪音。当频率低于20kHz时，工作噪声不仅变大，而且可能超过职业安全卫生法或其他法规规定的安全噪声限值。在需要高功率去除污垢而不担心损坏工件表面的应用中，通常选择从20kHz到30kHz的较低清洁频率。此频率范围内的清洁频率通常用于清洁大型、重型零件或具有高密度材料的工件。20KHz磁性换能器和25KHz压电换能器。

Noise occurs when the operating frequency is very low (within the range of human hearing). When the frequency is lower than 20kHz, the working noise not only becomes larger, but also may exceed the safety noise limit specified by the occupational safety and health law or other regulations. In applications that require high power to remove dirt without fear of damaging the workpiece surface, a lower cleaning frequency from 20kHz to 30kHz is usually selected. The cleaning frequency within this frequency range is usually used to clean large, heavy parts or workpieces with high-density materials. 20kHz magnetic transducer and 25kHz piezoelectric transducer.

高频通常用于清洁更小、更精细的部件，或去除微小颗粒。高频也用于不允许损坏工件表面的应用中。使用高频可以通过多种方式提高清洁性能。随着频率的增加，空化气泡的数量线性增加，产生更多更密集的冲击波，可以穿透更小的间隙。如果功率不变，空化气泡变小，其释放的能量也相应减少，有效减少了对工件表面的损伤。高频的另一个优点是它减少了粘性边界层（波努利效应），使超声波能够检测到极细的颗粒。这种情况类似于在水位下降时看到小溪底部的小鹅卵石。

High frequency is usually used to clean smaller and finer parts or remove small particles. High frequency is also used in applications where damage to the workpiece surface is not allowed. Using high frequency can improve cleaning performance in many ways. With the increase of frequency, the number of cavitation bubbles increases linearly, producing more and more dense shock waves, which can penetrate smaller gaps. If the power is constant, the cavitation bubble becomes smaller, and the energy released by it is reduced accordingly, which effectively reduces the damage to the workpiece surface. Another advantage of high frequency is that it reduces the viscous boundary layer (Bernoulli effect), enabling ultrasound to detect very fine particles. This is similar to seeing the pebbles at the bottom of the stream when the water level drops.

超声波清洗机清洗液

超声波清洗机生产厂家提醒您，不同的清洗液，清洗系统水基系统要加以区分：通常由一个开口槽组成，工件浸没在其中。复杂的系统由多个水箱组成，并配有循环过滤系统、淋浴水箱、干燥箱等配件。溶剂系统多为超声波汽相脱脂清洗机，常配备连续废液回收装置。

The manufacturer of ultrasonic cleaning machine reminds you that the water-based system of cleaning system should be distinguished for different cleaning solutions: it is usually composed of an open groove in which the workpiece is immersed. The complex system consists of multiple water tanks, and is equipped with circulating filtration system, shower water tank, drying oven and other accessories. Solvent systems are mostly ultrasonic vapor degreasing cleaning machines, often equipped with continuous waste liquid recovery devices.

超声波汽相去除油脂是由溶剂蒸发罐和超声波浸渍罐组成的一体化多罐系统完成的。油、油脂、蜡和其他溶剂可溶性污垢通过结合使用热溶剂蒸汽和超声波搅拌来去除。经过一系列清洗工序后卸出的工件是热的、干净的、干燥的。

Ultrasonic vapor phase grease removal is completed by an integrated multi tank system composed of solvent evaporation tank and ultrasonic impregnation tank. Oil, grease, wax and other solvent soluble dirt are removed by a combination of hot solvent steam and ultrasonic stirring. The workpiece unloaded after a series of cleaning procedures is hot, clean and dry.

此外廉价的清洗溶剂的使用成本并不一定低。使用中必须考虑到溶剂的清洗效率、安全性、一定量的溶剂可清洗多少工件利用率高等因素。当然，所选择的清洗溶剂必须达到清洗效果，并应与所清洗的工件材料相容。更多相关内容就来关注我们网站www.jnthcsb.com吧！

In addition, the cost of using cheap cleaning solvents is not necessarily low. The cleaning efficiency and safety of the solvent, the number of workpieces that can be cleaned with a certain amount of solvent, and the high utilization rate must be considered in the use. Of course, the selected cleaning solvent must achieve the cleaning effect and be compatible with the workpiece material to be cleaned. Let's pay more attention to our website!
