超聲波清洗機(jī)以其良好的清洗性能,現(xiàn)在被很多客戶認(rèn)可,使用。目前應(yīng)用于很多行業(yè),幫助客戶解決清洗難題。
With its good cleaning performance, ultrasonic cleaning machine is now recognized and used by many customers. At present, it is used in many industries to help customers solve cleaning problems.
但目前也有很多客戶對(duì)超聲波清洗機(jī)接觸還是比較少,會(huì)產(chǎn)生一定的誤區(qū):超聲波的頻率跟功率是不是越大,清洗效果越好?其實(shí)不是這樣的。今天來(lái)講解下有關(guān)超聲波清洗機(jī)的頻率跟功率問(wèn)題。
However, at present, many customers still have little contact with the ultrasonic cleaning machine, which will lead to some misunderstandings: is the greater the ultrasonic frequency and power, the better the cleaning effect? Not really. Today, let's talk about the frequency and power of ultrasonic cleaning machine.
超聲波頻率的選擇:
Selection of ultrasonic frequency:
低頻率:超聲波空化閥值與頻率有密切關(guān)系。頻率越高,空化閥值越高,頻率低,空化閥值越低,越容易產(chǎn)生空化,有利于清洗作用,但易損傷腐蝕工件表面,因此對(duì)工件表面要求較高的工件不適合選擇較低的頻率,低頻超聲波清洗一般適用于大型工件表面或者污物與工件表面粘合度高的情況下使用。而頻率越低,空化越強(qiáng)烈,產(chǎn)生的噪音也相應(yīng)偏大。
Low frequency: ultrasonic cavitation threshold is closely related to frequency. The higher the frequency, the higher the cavitation threshold, and the lower the frequency. The lower the cavitation threshold, the easier it is to produce cavitation, which is conducive to cleaning, but it is easy to damage and corrode the workpiece surface. Therefore, the workpiece with higher requirements on the workpiece surface is not suitable to choose a lower frequency. Low frequency ultrasonic cleaning is generally suitable for large workpiece surface or when the adhesion between dirt and workpiece surface is high. The lower the frequency, the stronger the cavitation, and the higher the noise.
高頻率:高頻率的超聲波穿透力較強(qiáng),宜清洗工件表面光潔度要求較高或表面復(fù)雜、盲孔,細(xì)縫較多的工件。高頻超聲波的噪音也偏小,適合于清洗一些精 密工件,比如半導(dǎo)體,飛機(jī)精 密工件等。
High frequency: high frequency ultrasonic has strong penetration, and it is suitable to clean workpieces with high surface finish requirements or workpieces with complex surface, blind holes and many fine cracks. The noise of high-frequency ultrasonic is also low, which is suitable for cleaning some precision workpieces, such as semiconductors, aircraft precision workpieces, etc.
經(jīng)濟(jì)性:從超聲波清洗效果及經(jīng)濟(jì)性來(lái)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(lái)確定。
Economy: considering the effect and economy of ultrasonic cleaning, the frequency is generally 20 ~ 130KHz, and the specific frequency should be determined by corresponding experiments.
超聲波功率的選擇:
Selection of ultrasonic power:
超聲波功率太大,液體中空化強(qiáng)度就會(huì)大大增加,容易使工件表面受到空化腐蝕,給工件造成不必要的損失跟消耗,同時(shí)清洗槽底部振動(dòng)板也會(huì)受到空化腐蝕影響,使清洗槽的壽命縮短。
If the ultrasonic power is too large, the cavitation intensity in the liquid will be greatly increased, which is easy to cause cavitation corrosion on the surface of the workpiece, causing unnecessary loss and consumption to the workpiece. At the same time, the vibrating plate at the bottom of the cleaning tank will also be affected by cavitation corrosion, shortening the service life of the cleaning tank.
但超聲波清洗功率選擇小了,花費(fèi)很長(zhǎng)時(shí)間也沒(méi)有清洗污垢,也是不可取的。
However, the choice of ultrasonic cleaning power is small, and it takes a long time to clean the dirt, which is also undesirable.
常規(guī)的超聲波清洗在工業(yè)當(dāng)中,標(biāo)準(zhǔn)型超聲波清洗機(jī)從100W至1500W不等,工件有多大,在考慮清洗節(jié)拍的前提下,由超聲波清洗槽體的大小決定超聲波的功率。
Conventional ultrasonic cleaning in the industry, the standard ultrasonic cleaning machine ranges from 100W to 1500W. The size of the workpiece depends on the size of the ultrasonic cleaning tank on the premise of considering the cleaning beat.
以上。超聲波清洗機(jī)功率過(guò)大,清洗力度過(guò)強(qiáng),對(duì)工件表面的損害性會(huì)越強(qiáng),對(duì)于表面較脆弱的物體,需要謹(jǐn)慎考慮功率的大小。功率越大,價(jià)格自然也越高,因此不要盲目追求大功率,應(yīng)從經(jīng)濟(jì)實(shí)用的角度來(lái)考慮。
above. If the power of ultrasonic cleaning machine is too large and the cleaning force is too strong, the damage to the workpiece surface will be stronger. For objects with fragile surface, the power needs to be carefully considered. The higher the power, the higher the price. Therefore, do not blindly pursue high power, and consider it from the perspective of economy and practicality.
