多槽手動超聲波清洗機(jī)與頻率有密切關(guān)系。頻率越高，清洗效果越高。頻率低，清洗效果越低，越容易產(chǎn)生空化。在低頻情況下，液體受到壓縮與稀疏作用的時(shí)間間隔更長。使氣泡能生長到更大尺寸，增強(qiáng)空化強(qiáng)度，有利于清洗作用。所以低頻超聲波清洗一般在大型部件表面或者污物與工件表面粘合度高的情況下使用。但易損傷腐蝕工件表面。所以對工件表面要求較高的零件不適合選擇較低的頻率。而且頻率低，產(chǎn)生的噪音也相應(yīng)偏大。高頻率的超聲波穿透力較強(qiáng)，宜清洗清洗表面光潔度要求較高或表面復(fù)雜、盲孔較多的部件。

The multi slot manual ultrasonic cleaning machine is closely related to frequency. The higher the frequency, the higher the cleaning effect. The lower the frequency, the lower the cleaning effect, and the easier it is to produce cavitation. At low frequencies, the time interval between compression and sparsity of liquids is longer. Enable bubbles to grow to larger sizes, enhance cavitation intensity, and facilitate cleaning. So low-frequency ultrasonic cleaning is generally used on the surface of large components or when the adhesion between dirt and the workpiece surface is high. But it is easy to damage and corrode the surface of the workpiece. So parts with high surface requirements for workpieces are not suitable for choosing lower frequencies. Moreover, the frequency is low and the generated noise is correspondingly high. High frequency ultrasonic waves have strong penetration power and are suitable for cleaning parts with high surface smoothness requirements or complex surfaces with many blind holes.

另一方面高頻超聲波的噪音也偏小，適合于清洗一些精密零件，如一些電子零件、小型軸承加工、磁性材料等。而對于一些特殊工件如集成電路芯片、硅片鍍膜的清清則選則更高頻率的超聲波來進(jìn)行清洗為宜。而對于一些大的工件如汽車發(fā)動機(jī)、閥門等大型工件應(yīng)選擇低頻的超聲波進(jìn)行清洗。另一方面超聲波清洗效果及經(jīng)濟(jì)性來考慮，一般選取頻率在20~130KHz。具體選擇頻率應(yīng)做相應(yīng)的實(shí)驗(yàn)來確定。

On the other hand, the noise of high-frequency ultrasound is also relatively low, making it suitable for cleaning some precision parts, such as electronic components, small bearing processing, magnetic materials, etc. For some special workpieces such as integrated circuit chips and silicon wafer coatings, it is advisable to use higher frequency ultrasonic waves for cleaning. For some large workpieces such as car engines, valves, etc., low-frequency ultrasonic waves should be selected for cleaning. On the other hand, considering the effectiveness and economy of ultrasonic cleaning, the frequency is generally selected between 20-130KHz. The specific frequency selection should be determined through corresponding experiments.

1. 清洗的工件：應(yīng)該清楚的了解需要清洗的產(chǎn)品材質(zhì)構(gòu)成、形狀結(jié)構(gòu)、尺寸大小、清洗量、 清洗潔凈度要求、清洗完成后工序是什么等。

1. Workpiece to be cleaned: It is necessary to have a clear understanding of the material composition, shape and structure, size, cleaning amount, cleaning cleanliness requirements, and the process after cleaning of the product to be cleaned.

2. 需清洗的污物：要清楚清洗工件的油污形狀，比如：沖壓拉升油脂、拋光臘、積炭、灰塵、指紋等。

2. Dirt to be cleaned: It is necessary to clearly clean the shape of the oil stains on the workpiece, such as stamping and pulling grease, polishing wax, carbon deposits, dust, fingerprints, etc.

3. 清洗工藝：根據(jù)工件的特質(zhì)及污質(zhì)情況選擇合理的超聲波清洗設(shè)備工藝，您可以咨詢相關(guān)人員為您提供這方面的建議，或者請廠家為您提供工藝實(shí)驗(yàn)來完善清洗工藝，清洗工藝的選擇是設(shè)備制造前的重要部分，一定要選擇正確的工藝，否則影響將來長期的清洗效果。

3. Cleaning process: Choose a reasonable ultrasonic cleaning equipment process based on the characteristics and pollution of the workpiece. You can consult relevant personnel for advice in this regard, or ask the manufacturer to provide process experiments to improve the cleaning process. The selection of cleaning process is an important part before equipment manufacturing, and it is necessary to choose the correct process, otherwise it will affect the long-term cleaning effect in the future.

功率的強(qiáng)弱大小對工件的清洗效果好環(huán)及清洗時(shí)間是一個(gè)直接決定因素。功率強(qiáng)弱大小是根擾工件結(jié)構(gòu)及工件在槽內(nèi)擺放方式來選擇超聲波的輻射分布方式等。來計(jì)算發(fā)射面所需要超聲波功率的大小。超聲波功率大小計(jì)算采用國際通的標(biāo)準(zhǔn)方式來計(jì)算。 一通常來說超聲波清洗機(jī)的清洗頻率選擇為28KHZ和40KHZ比較多，對工件表面要求極微小的顆粒及表面不允許損傷的才選用較高的頻率。

The strength of power is a direct determining factor for the cleaning effect and cleaning time of workpieces. The strength of power is determined by the structure of the workpiece and the placement of the workpiece in the groove to choose the radiation distribution of ultrasonic waves. To calculate the required ultrasonic power for the emitting surface. The calculation of ultrasonic power is carried out using the internationally recognized standard method. Generally speaking, the cleaning frequency of ultrasonic cleaning machines is selected between 28KHZ and 40KHZ, which are more common. Only those that require extremely small particles on the surface of the workpiece and do not allow damage to the surface should choose higher frequencies.
